THE STRANGE DISAPPEARANCE OF THE BEES is a frightening documentary about how mass deaths of bees have recently swept all over the world. Increasingly each spring, beekeepers open their hives to find entire colonies wiped out. And beekeepers aren't the only ones who are worried. Bees pollinate at least a third of the world's crops. If the dramatic decline in worldwide bee populations continues, essential food crops could disappear, along with entire ecosystems.
Bringing together the latest scientific research, THE STRANGE DISAPPEARANCE OF THE BEES looks at the dramatic colony collapses in beehives around the world. There is no one smoking gun responsible for killing bees. Instead, a constellation of factors is stressing bees more than ever before: from parasitic mites that infect them with deadly viruses, to novel pesticides incorporated into the very cells of plants, and industrial operations that truck millions of bees all over the country.
California's Imperial Valley provides an almost perfect storm of these factors, with 36 billion bees providing essential pollination for nearly a million acres of almond trees. When the trees are in bloom, the Valley looks like a lush paradise. But it's a pesticide-intensive environment in which bees are under such strain they need to be artificially fed-and even then, many perish.
But bees don't have to live under these conditions, and beekeepers don't need to adopt them in order to succeed. In Scotland, Willie Robson has become one of the country's most productive beekeepers, using natural methods to breed and raise his insects. Rather than breeding bees for docility, he encourages natural selection that boosts bees' immunity.
Featuring stunning photography, THE STRANGE DISAPPEARANCE OF THE BEES takes us right into beehives and onto plants along with the pollinators. It also surveys the science through conversations with top researchers such as entomologist May Berenbaum of the University of Illinois at Urbana-Champaign, and biologist Paul Ehrlich of Stanford's Center for Conservation Biology.
There may be no easy answers as to why bee colonies are collapsing, but this documentary makes a convincing case that the current industrial agricultural model may to blame-killing off the very pollinators that it requires in order to survive. As Ehrlich puts it, bees have the task of keeping the world alive. If they go in sufficient numbers, we may well follow.
'Highly Recommended. THE STRANGE DISAPPEARANCE OF THE BEES is perhaps the most disturbing documentary to date about the rapidly declining populations of both commercial and wild honeybees. ...a sound, methodical and scientific indictment of the industrial, modern agriculture complex and its profound impact on the health of the environment. ...The reviewer highly recommends this title for academic, public, and school library collections.' -Educational Media Reviews Online
** 'Highly Recommended. Colony Collapse Disorder (CCD) is the focus of this program. The overall tone of the video is serious but the seriousness is warranted because CCD is not caused by a single pathogen but instead is brought about by the synergy of several factors. ...Excellent footage of varroa mites illustrates a honey bee parasite that can transfer viruses to bees. ...thorough introduction to the complexities of CCD and the potential ramifications of continued decline of domestic honey bee populations.' -Janet R. Mihuc, Paul Smith's College, Paul Smith's NY, Science Books and Films
'This is an outstanding addition to recent films looking into the phenomenon of disappearing honeybees. ...filmmaker Daniels widens the scope to include wild bee populations in precipitous decline, including species extinction. Commercial beekeepers, forced to supplement the diets of the bees they deploy in monocultural agriculture (pollinating a specific food crop), realize they are working their bees to death. Still, wild bees adapted to a more diverse and nutritious pollen diet are dying, too. ...Most sobering: scientific experts envisioning a world without bees or, alternatively, an agriculture pollinated by genetically engineered bees. VERDICT This documentary is very highly recommended for all audiences.' -Library Journal

00:00:00.000 --> 00:00:04.999
Bees are everywhere,
00:00:05.000 --> 00:00:09.999
all but unnoticed as they say
fly from flower to flower.
00:00:10.000 --> 00:00:14.999
They have existed much longer than men.
But over the last 8,000 years
00:00:15.000 --> 00:00:19.999
man and bee have become partners.
00:00:20.000 --> 00:00:24.999
In 2006, reports came out of America that millions
of bees had disappeared from their hives.
00:00:25.000 --> 00:00:29.999
It sounds like a science fiction,
horror film, but it’s not.
00:00:30.000 --> 00:00:34.999
Since the mid 1900s, beekeepers
have been extraordinary losses.
00:00:35.000 --> 00:00:39.999
Everywhere in the industrialized world,
00:00:40.000 --> 00:00:44.999
bees are dying and beekeepers
don’t know what to do.
00:00:45.000 --> 00:00:49.999
[music]
00:00:50.000 --> 00:00:54.999
Scientists from many disciplines
00:00:55.000 --> 00:00:59.999
have mobilized to confront
this global problem.
00:01:00.000 --> 00:01:04.999
In the last four years, what have they
learned? Can science provide an explanation,
00:01:05.000 --> 00:01:09.999
a cure, or a solution?
00:01:10.000 --> 00:01:14.999
Is it too late to save this tiny creature
and from extinction? Why should we care?
00:01:15.000 --> 00:01:23.000
[music]
00:01:45.000 --> 00:01:49.999
[sil.]
00:01:50.000 --> 00:01:54.999
Each year, beekeepers everywhere
performed the same spring ritual.
00:01:55.000 --> 00:01:59.999
And on sunny day, they open their hives to see
how their bees survive the rigors of winter.
00:02:00.000 --> 00:02:04.999
Over the last four years this
ritual has become a nightmare.
00:02:05.000 --> 00:02:09.999
In Europe, in America’s, beekeepers
find losses of 30 to 80%
00:02:10.000 --> 00:02:14.999
and no one knows why.
00:02:15.000 --> 00:02:19.999
It’s more than just my income.
00:02:20.000 --> 00:02:24.999
It’s… These are my girls, my bees, so I hate to
see, you know, I feel like I led them down some
00:02:25.000 --> 00:02:29.999
because you know, obviously we didn’t
do things right here possibly.
00:02:30.000 --> 00:02:34.999
We could have done more for them to save
them. So it’s uh… Yeah, it’s sad for sure.
00:02:35.000 --> 00:02:39.999
Like thousands of other beekeepers,
00:02:40.000 --> 00:02:44.999
Ben Hogan will have no
honey harvest the summer.
00:02:45.000 --> 00:02:49.999
But it’s not the loss of honey that
has scientists like Bernard Vaissiere
00:02:50.000 --> 00:02:54.999
at the French National Institute for Agricultural
Research devoting countless hours to studying bees.
00:02:55.000 --> 00:02:59.999
Bees are fundamental to
the human food chain.
00:03:00.000 --> 00:03:04.999
Most of our food crops are pollinated by bees and that
includes almost every fruit, vegetable, oil, and not.
00:03:05.000 --> 00:03:10.000
[music]
00:03:40.000 --> 00:03:44.999
[music]
00:03:45.000 --> 00:03:49.999
Seeking nectar at the heart of the flower,
00:03:50.000 --> 00:03:54.999
bees inadvertently transfer pollen to the female
organ of the plant. The elaborate beauty of flowers
00:03:55.000 --> 00:03:59.999
is not evolved simply for our pleasure,
it serves to attract pollinators
00:04:00.000 --> 00:04:04.999
and signals a food source for bees.
00:04:05.000 --> 00:04:09.999
With fewer bees, crops
become less productive
00:04:10.000 --> 00:04:14.999
or toothless fruitful. And
scientists are asking
00:04:15.000 --> 00:04:19.999
what’s the fewest bees we can get away with
and still have a workable agriculture?
00:04:20.000 --> 00:04:24.999
It’s a question no one would have
thought to ask just a few years ago.
00:04:25.000 --> 00:04:29.999
But there is a global crisis in the making,
the agricultural demand for pollinators
00:04:30.000 --> 00:04:34.999
is growing much more
quickly than the supply.
00:04:35.000 --> 00:04:39.999
In 2006, the danger became clear,
melodies swept through American apiaries,
00:04:40.000 --> 00:04:44.999
bees simply started disappearing
leaving empty hives.
00:04:45.000 --> 00:04:49.999
Scientists named the phenomenon
Colony Collapse Disorder, CCD.
00:04:50.000 --> 00:04:54.999
Alarmed by the sudden threat to the
national agricultural economy,
00:04:55.000 --> 00:04:59.999
the US Congress called on
beekeepers and scientists
00:05:00.000 --> 00:05:04.999
to explain the deadly melody. For a moment
anyway, the bees had a voice in Congress.
00:05:05.000 --> 00:05:09.999
May Berenbaum spoke for the
CCD Scientific Task Force.
00:05:10.000 --> 00:05:14.999
Even before CCD we estimated
00:05:15.000 --> 00:05:19.999
if honeybee numbers continue to decline at
the rates documented from 1989 to 1996,
00:05:20.000 --> 00:05:24.999
managed honeybees in United States
will cease to exist by 2035.
00:05:25.000 --> 00:05:29.999
Colony Collapse Disorder is an unusual phenomenon
characterized by the sudden massive disappearance
00:05:30.000 --> 00:05:34.999
of the majority of workers
in honeybee colony,
00:05:35.000 --> 00:05:39.999
leaving behind viable brood or larvae,
00:05:40.000 --> 00:05:44.999
small contingent of nurse bees and a
healthy Queen and abundant food supplies.
00:05:45.000 --> 00:05:49.999
Colony Collapse Disorder progressed
inexorably from state to state.
00:05:50.000 --> 00:05:54.999
Everywhere the same
scenario, abandoned brood,
00:05:55.000 --> 00:05:59.999
abandoned honey, no
corpses around the hives.
00:06:00.000 --> 00:06:04.999
Urgency mounted as a total
of 35 states were affected.
00:06:05.000 --> 00:06:09.999
Scientists suspected a new pathogen, perhaps
a newly introduced or mutated virus.
00:06:10.000 --> 00:06:14.999
One of the early discoveries
was a new virus
00:06:15.000 --> 00:06:19.999
Israeli Acute Paralysis Virus, which had
never been described before in America
00:06:20.000 --> 00:06:24.999
and that got a lot of attention. And in that initial
screening, there was a relationship that we still see
00:06:25.000 --> 00:06:29.999
between that virus and CCD.
00:06:30.000 --> 00:06:34.999
The breakthrough promise to cure a magic
bullet, but hope was short-lived.
00:06:35.000 --> 00:06:39.999
As a complete explanatory factor
Israeli Acute Paralysis Virus
00:06:40.000 --> 00:06:44.999
really fell short a few months
after that report was released,
00:06:45.000 --> 00:06:49.999
when other investigators
went into their freezers
00:06:50.000 --> 00:06:54.999
and pulled out specimens and demonstrated that
IAPV has been in the US since at least 2002,
00:06:55.000 --> 00:06:59.999
which entities the appearance
of Colony Collapse Disorder.
00:07:00.000 --> 00:07:04.999
A dead end. And scientists
have had to ask themselves,
00:07:05.000 --> 00:07:09.999
if this phenomenon might not have a single
cause, is it a convergence of several factors
00:07:10.000 --> 00:07:14.999
or is there one primary
cause that weakens bees,
00:07:15.000 --> 00:07:19.999
allowing pathogens to take a heavy toll? For now at rest
just a sudden disappearance of bees, cause unknown.
00:07:20.000 --> 00:07:24.999
Pesticides have been
invoked virus diseases,
00:07:25.000 --> 00:07:29.999
have been invoked cell telephones been invoked, UFOs
have been invoked, all sorts of sort of things.
00:07:30.000 --> 00:07:34.999
Some of them sensible, some
of them just cockamamie,
00:07:35.000 --> 00:07:39.999
but nonetheless we really don’t
know what uh… what initiates it.
00:07:40.000 --> 00:07:44.999
The mystery only deepened as reports came
in of Colony Collapse around the world.
00:07:45.000 --> 00:07:49.999
Massive bee deaths in South America,
00:07:50.000 --> 00:07:54.999
in Taiwan, in China, in India.
00:07:55.000 --> 00:07:59.999
Five million bees reported disappeared
in just 48 hours in Croatian
00:08:00.000 --> 00:08:04.999
and all over the rest of Europe,
millions of unexplained deaths.
00:08:05.000 --> 00:08:09.999
But is it a single illness
without a recognized cause,
00:08:10.000 --> 00:08:14.999
it’s impossible to say.
00:08:15.000 --> 00:08:19.999
Summer in Provence is a sun drenched
paradise for bees and beekeepers,
00:08:20.000 --> 00:08:24.999
but there’s trouble in paradise.
00:08:25.000 --> 00:08:29.999
Even here, bee populations have
been steadily and quietly declining
00:08:30.000 --> 00:08:34.999
for more than 60 years.
00:08:35.000 --> 00:08:39.999
Everywhere in the world,
00:08:40.000 --> 00:08:44.999
declines in bee populations, have followed
the development of industrial agriculture.
00:08:45.000 --> 00:08:49.999
The post-world war demanded
food for a hungry population.
00:08:50.000 --> 00:08:54.999
And in the name of
efficiency and productivity,
00:08:55.000 --> 00:08:59.999
chemicals and machines would
turn to a war against nature.
00:09:00.000 --> 00:09:04.999
Government policies transformed the landscape
to serve the needs of modern agriculture.
00:09:05.000 --> 00:09:09.999
Pedro’s were plowed under,
field enlarged and leveled,
00:09:10.000 --> 00:09:14.999
technicians replace farmers as agricultural
specialists and beekeepers faced a new challenge
00:09:15.000 --> 00:09:20.000
as every insect was chased
from every flowering crop.
00:10:05.000 --> 00:10:09.999
In the night, when the
bees are in their hives,
00:10:10.000 --> 00:10:14.999
Jean and Rémi Brun move their colonies.
Sixteen hours of grueling work,
00:10:15.000 --> 00:10:19.999
two million bees moved over 200
kilometers from (inaudible)
00:10:20.000 --> 00:10:24.999
to the lavender fields of Provence.
Despite heavy stress on the bees,
00:10:25.000 --> 00:10:29.999
they have to do it twice a year now, both
to protect their babies from insecticides
00:10:30.000 --> 00:10:34.999
and to bring them to fresh flowers.
00:10:35.000 --> 00:10:39.999
But there is yet another threat
for the bees to deal with.
00:10:40.000 --> 00:10:45.000
In the 1980s, a new pest arrived in France
destroying bee colonies and beekeepers.
00:11:10.000 --> 00:11:14.999
Varroa seen among bee colonies in Asia.
00:11:15.000 --> 00:11:19.999
Over the last 30 years, a worldwide market
in Queens and especially bread Bees
00:11:20.000 --> 00:11:24.999
has spread Varroa into nearly every honeybee
colony in Europe, Africa, and the Americas.
00:11:25.000 --> 00:11:29.999
Varroa is parasitic blood-sucking might.
00:11:30.000 --> 00:11:34.999
It’s very small, it’s only about
two millimeters in diameter
00:11:35.000 --> 00:11:39.999
and it fixes onto the bee’s body like a crab
louse and it bites the bee and sucks its blood.
00:11:40.000 --> 00:11:44.999
And in the process of doing that, it…
it infects the bee with any virus
00:11:45.000 --> 00:11:49.999
that it has to be carrying. So the overall
effect on a bee colonies, it weakens the bees
00:11:50.000 --> 00:11:54.999
and they tend to get viruses
and in particular the queen,
00:11:55.000 --> 00:11:59.999
who lives a lot longer than the other
bees, she tends to be badly affected.
00:12:00.000 --> 00:12:04.999
Fighting Varroa is trying to kill a bug
on a bug. It’s hard to find a chemical
00:12:05.000 --> 00:12:09.999
to kill the mind and not harm the bee.
00:12:10.000 --> 00:12:14.999
Overtime, the chemicals lodge in the wax
defusing a constant low dosage of pesticide
00:12:15.000 --> 00:12:19.999
and then a cruel and vicious circle that
might become resistant and the bees weaken,
00:12:20.000 --> 00:12:24.999
do without chemicals, the colony dies.
00:12:25.000 --> 00:12:29.999
And so the introduction of Varroa
mite into the country and the 1980s
00:12:30.000 --> 00:12:34.999
had a real effect on the ability of viruses
to get transmitted from colony to colony.
00:12:35.000 --> 00:12:39.999
And so that’s probably what’s killing most of
the colonies. We’re usually blamed Varroa,
00:12:40.000 --> 00:12:45.000
but it’s probably the viruses that
the Varroa mite are… are mediating.
00:13:20.000 --> 00:13:24.999
Bees with this remarkable
trait of resistance,
00:13:25.000 --> 00:13:29.999
managed to control the population of
Varroa mite by killing infected poopy
00:13:30.000 --> 00:13:34.999
and ejecting them from the colony. It’s
a real form of social cooperation.
00:13:35.000 --> 00:13:39.999
But how do these resistant honeybees differ
from those millions dying from Varroa?
00:13:40.000 --> 00:13:44.999
[sil.]
00:13:45.000 --> 00:13:49.999
Dr. Le Conte send samples to Gene Robinson,
00:13:50.000 --> 00:13:54.999
leader of the team that sequenced
the honeybee genome in 2006.
00:13:55.000 --> 00:13:59.999
My colleague Yves Le Conte in France has identified
some honeybees, some strains of honeybees
00:14:00.000 --> 00:14:04.999
that are more resistant to
Varroa than other strains.
00:14:05.000 --> 00:14:09.999
He sent samples of those
strains to my laboratory
00:14:10.000 --> 00:14:14.999
and we analyzed their gene activity
using the microarray technique
00:14:15.000 --> 00:14:19.999
to see if we might get some clues
about the basis for the resistance.
00:14:20.000 --> 00:14:24.999
And we were very pleasantly surprised
to see that the main differences
00:14:25.000 --> 00:14:29.999
between the strains that are more resistant to
Varroa compared to those that are more susceptible.
00:14:30.000 --> 00:14:34.999
The main differences had to do with activity
and genes associated with behavior.
00:14:35.000 --> 00:14:39.999
Varroa resistance is a collective
00:14:40.000 --> 00:14:44.999
rather than individual form of immunity,
it’s called hygienic behavior.
00:14:45.000 --> 00:14:49.999
Compared to other insects that have been
sequenced, honeybees have fewer genes for immunity
00:14:50.000 --> 00:14:54.999
and detoxification. The
individual is by nature weak
00:14:55.000 --> 00:14:59.999
in the face of pathogens and poisons.
00:15:00.000 --> 00:15:04.999
But incredibly strong genetic
disposition for social cooperation
00:15:05.000 --> 00:15:09.999
can compensate in part for this
weakness in individual honeybees genes.
00:15:10.000 --> 00:15:14.999
The gene suggests that the resistant
strains may be more sensitive
00:15:15.000 --> 00:15:19.999
to some odors associated
with the presence of Varroa.
00:15:20.000 --> 00:15:24.999
That kind of information can lead to
improvements in breeding strategies,
00:15:25.000 --> 00:15:29.999
to be able to breed more
resistant honeybees.
00:15:30.000 --> 00:15:34.999
But is it really quite
so easy as it sounds?
00:15:35.000 --> 00:15:39.999
Artificial insemination is more suited to
the laboratory than they are appearing.
00:15:40.000 --> 00:15:44.999
The Tibor Szabo, senior and junior are commercial
Queen breeders and with bees dying everywhere,
00:15:45.000 --> 00:15:49.999
business is good.
00:15:50.000 --> 00:15:54.999
The scientists all over the world they are talking about,
you know, we… we want to breed bees, resist on to demise
00:15:55.000 --> 00:15:59.999
or some of them they are tolerant
to demise. But how can we get that?
00:16:00.000 --> 00:16:04.999
Breeding a bee that’s resistant to Varroa mite is
like breeding sheep that are resistant to wolves.
00:16:05.000 --> 00:16:09.999
Yeah. It maybe possible but it’s
extremely and we are not sure how.
00:16:10.000 --> 00:16:14.999
The bees have an incredible reproductive
potential. And as long as we can maximize it,
00:16:15.000 --> 00:16:19.999
we can stay ahead of a lot of its
problems, but it’s a constant effort.
00:16:20.000 --> 00:16:28.000
[music]
00:16:30.000 --> 00:16:34.999
The life of the colony
depends on the Queen.
00:16:35.000 --> 00:16:39.999
There’s only one. She’s the
mother of every bee in the hive.
00:16:40.000 --> 00:16:44.999
Workers feed and groom her day and night and
encourage her to lay up to 2,000 eggs up day.
00:16:45.000 --> 00:16:49.999
She gives off a chemical signal, a pheromone,
that calms and coordinates the workers.
00:16:50.000 --> 00:16:54.999
Should have pheromone weaken
or should she stop laying,
00:16:55.000 --> 00:16:59.999
the workers will raise a new queen.
A queen less colony is doomed.
00:17:00.000 --> 00:17:04.999
The art of the breeder is
to trick the worker bees
00:17:05.000 --> 00:17:09.999
into thinking they need a new queen.
00:17:10.000 --> 00:17:14.999
There’s line in each cage, we do that
because if they can access each other,
00:17:15.000 --> 00:17:19.999
they’d fight. The queens are
worth between $20 and $30 each
00:17:20.000 --> 00:17:24.999
depending on the amount
that the customer buys.
00:17:25.000 --> 00:17:29.999
If they buy over 100 queens, here they are $20 each,
so this box will be worth $2080 to the beekeeper.
00:17:30.000 --> 00:17:34.999
You could make 104 hives with this one box.
00:17:35.000 --> 00:17:39.999
[sil.]
00:17:40.000 --> 00:17:44.999
The market determines the character of honeybees.
Beekeepers favorite bees that are gentle and productive
00:17:45.000 --> 00:17:49.999
and that’s what breeders try to deliver.
In North America, just a few 100 breeders
00:17:50.000 --> 00:17:54.999
supply the hundreds of thousands of Queens
bought and sold on the continent each year.
00:17:55.000 --> 00:17:59.999
The result is an increase in
the uniform bee population,
00:18:00.000 --> 00:18:04.999
made worse by the fact that honeybees
are not native to North America,
00:18:05.000 --> 00:18:09.999
they were imported by colonists in the 17th
century. All the bees share a limited gene pool.
00:18:10.000 --> 00:18:14.999
[music]
00:18:15.000 --> 00:18:19.999
Anytime you have a lack of diversity, the population is more
likely to be susceptible to diseases or to… to problems.
00:18:20.000 --> 00:18:24.999
And so we do think that… that is
potentially one of the things
00:18:25.000 --> 00:18:29.999
that could be contributing. We don’t think it’s
the cause of CCD or a decline of honeybees.
00:18:30.000 --> 00:18:34.999
But as far as honey bees go, it
could be one of the weaknesses in…
00:18:35.000 --> 00:18:39.999
in our population of honeybees.
If bees around the world are weak
00:18:40.000 --> 00:18:44.999
in the phase of disease,
it’s largely due to man.
00:18:45.000 --> 00:18:49.999
Trying to breed the perfect bee
can eliminate trades bees need
00:18:50.000 --> 00:18:54.999
in order to adapt to a
changing environment.
00:18:55.000 --> 00:18:59.999
Long before man appeared, bees were
adapting to local conditions on their own,
00:19:00.000 --> 00:19:04.999
tuning themselves to their regions.
Tough black bees from northern latitude
00:19:05.000 --> 00:19:09.999
learn to store more honey in a shorter time
00:19:10.000 --> 00:19:14.999
to survive a long winter.
00:19:15.000 --> 00:19:19.999
The aggressive native Black Bee has learned
to live in this harsh Scottish climate
00:19:20.000 --> 00:19:24.999
through thousands of
generations of adaptation
00:19:25.000 --> 00:19:29.999
and Willie Robson has adapted
his beekeeping to their needs.
00:19:30.000 --> 00:19:34.999
Our father taught beekeeping in the 50s.
And I remember my father saying, well,
00:19:35.000 --> 00:19:39.999
we’ll start away with those that die good
returns. And from then on we’ve worked on…
00:19:40.000 --> 00:19:44.999
on that principle. That if they
didn’t manage to survive the winter
00:19:45.000 --> 00:19:49.999
than that was a good… that was a good way to
be. And our aim which is what we’ve achieved
00:19:50.000 --> 00:19:54.999
is to have total natural resistance
to all unknown diseases of bees.
00:19:55.000 --> 00:19:59.999
As Varroa progresses we’ll have to hope that they
will start to become resistant to that as well
00:20:00.000 --> 00:20:04.999
and that probably will
occur not in my lifetime
00:20:05.000 --> 00:20:09.999
but within the next 50 years. The bees are
well able to adapt to these sort of things.
00:20:10.000 --> 00:20:14.999
Using traditional methods,
00:20:15.000 --> 00:20:19.999
Willie Robson has become one of the largest honey
producers in Scotland. The foundation of this philosophy
00:20:20.000 --> 00:20:24.999
is a simple trust in nature.
00:20:25.000 --> 00:20:29.999
I think as soon as you start
breeding them pure for docility,
00:20:30.000 --> 00:20:34.999
and honey production, uh… you breed out
00:20:35.000 --> 00:20:39.999
a whole lot of other necessary qualities
00:20:40.000 --> 00:20:44.999
and that brings in itself trouble. Once you
breed out that the disease resistant element,
00:20:45.000 --> 00:20:49.999
uh… you never recover, that
never… never recovered,
00:20:50.000 --> 00:20:54.999
then… then you’re required to put in
chemicals to control the disease.
00:20:55.000 --> 00:20:59.999
There’s only a very fine line that you
can take when meddling when nature
00:21:00.000 --> 00:21:04.999
before you get into trouble, you k now.
And the trouble cost you ten times
00:21:05.000 --> 00:21:09.999
as much as you would think, you know.
Trouble gets in…
00:21:10.000 --> 00:21:14.999
Trouble with anything, any living thing
is…is a real headache, you know.
00:21:15.000 --> 00:21:19.999
In an ideal world, Willie
Robson would be a model,
00:21:20.000 --> 00:21:24.999
but it’s too late. If beekeepers everywhere
00:21:25.000 --> 00:21:29.999
adopted total natural resistance,
most of their bees would die.
00:21:30.000 --> 00:21:35.000
Without this large scale force of pollinators,
the entire agricultural economy would collapse.
00:22:15.000 --> 00:22:19.999
Agriculture developed over centuries
00:22:20.000 --> 00:22:24.999
in an environment with a diversity of pollinators.
The domestic honeybees just one of many bees
00:22:25.000 --> 00:22:29.999
that visit crops.
00:22:30.000 --> 00:22:34.999
There are at least 19,000 species of wild bees
on the planet, but they’re disappearing too.
00:22:35.000 --> 00:22:39.999
[music]
00:22:40.000 --> 00:22:44.999
All right, this is a small one. So we got
over 30 species of bees in my backyard
00:22:45.000 --> 00:22:49.999
and that’s without me spending
much time looking for them.
00:22:50.000 --> 00:22:54.999
Is a little sweat bee.
Declines in wild bees
00:22:55.000 --> 00:22:59.999
have been documented since 1992, but
no one knows the original populations.
00:23:00.000 --> 00:23:04.999
Different species of bumblebees that used to be
fairly common have just gone through the flow.
00:23:05.000 --> 00:23:09.999
Some of them we can still find in out of the way
places, you know, high mountains in Colorado
00:23:10.000 --> 00:23:14.999
or in… in Northern BC, uh… but
we can’t find them in places
00:23:15.000 --> 00:23:19.999
where sometimes they made up 30% of the bees you’d
find somewhere, now they’re completely gone.
00:23:20.000 --> 00:23:24.999
Lawrence Packer, runs a largest
wild BEE Lab in the world.
00:23:25.000 --> 00:23:29.999
Wild bees are responsible for the pollinating
most of the wild flowers out there.
00:23:30.000 --> 00:23:34.999
And so imagine what would happen if all of a
sudden the reproduction of wild flowers stopped
00:23:35.000 --> 00:23:39.999
. There’d be no fruit and
berries to feed the birds.
00:23:40.000 --> 00:23:44.999
There’d be no nuts and berries to feed the
bears. The squirrels would be in trouble.
00:23:45.000 --> 00:23:49.999
The whole terrestrial ecosystem as
we know it would be very different
00:23:50.000 --> 00:23:54.999
if all of a sudden all of the bees disappear.
Some wild bees are very specialized pollinators.
00:23:55.000 --> 00:23:59.999
They might seek food from
a single flowering plant.
00:24:00.000 --> 00:24:04.999
And if the bee disappears,
so does the flower.
00:24:05.000 --> 00:24:10.000
You see a tulip there?
00:24:45.000 --> 00:24:49.999
[music]
00:24:50.000 --> 00:24:54.999
Wild bees don’t have Varroa. They don’t
have viruses in common with honeybees.
00:24:55.000 --> 00:24:59.999
But something is killing both populations.
00:25:00.000 --> 00:25:04.999
And the impact of loss pollinators
goes far beyond the human diet.
00:25:05.000 --> 00:25:09.999
For Paul Ehrlich,
00:25:10.000 --> 00:25:14.999
a founder of the science of co-evolution, bees
have the task of keeping the world alive.
00:25:15.000 --> 00:25:19.999
It’s very scary
00:25:20.000 --> 00:25:24.999
to see bees and other pollinators not doing well because
they are, what are sometimes called mobile links,
00:25:25.000 --> 00:25:29.999
they move around and connect things in nature. When the
things that connect things in nature aren’t doing well,
00:25:30.000 --> 00:25:34.999
that’s not a great sign. One of the most
important aspects of how evolution works,
00:25:35.000 --> 00:25:39.999
of how we get the organisms that populate
our planet, that support our lives
00:25:40.000 --> 00:25:44.999
and that of course evolution created us,
00:25:45.000 --> 00:25:49.999
is not just evolution operating under the,
pressure is created by the physical environment
00:25:50.000 --> 00:25:54.999
that is by cold or winds or something, but of
course other organisms create selection pressures.
00:25:55.000 --> 00:25:59.999
So that for example, uh… plants and
bees have evolved together over…
00:26:00.000 --> 00:26:04.999
overtime, so that the bees get
their nourishment from the plants
00:26:05.000 --> 00:26:09.999
and the plants get their sex from the bees.
00:26:10.000 --> 00:26:14.999
These kinds of co-evolutionary complexes are among the
most important aspects of the whole process of evolution.
00:26:15.000 --> 00:26:19.999
[sil.]
00:26:20.000 --> 00:26:24.999
It’s not just bees and flowers that
evolve together. Co-evolution is a web
00:26:25.000 --> 00:26:29.999
includes one creature that
has a critical impact
00:26:30.000 --> 00:26:34.999
on every living thing, man. For
the first time in history,
00:26:35.000 --> 00:26:39.999
the scale of the activities of the human
system finally are impinging in a big way
00:26:40.000 --> 00:26:44.999
on the natural system and that’s why
for the first time in human history
00:26:45.000 --> 00:26:49.999
we have the threat of a collapse
of a global civilization,
00:26:50.000 --> 00:26:54.999
or else we may go down the drain
in part because of the bees.
00:26:55.000 --> 00:27:03.000
[music]
00:27:05.000 --> 00:27:09.999
There is a place where all
the elements of collapse
00:27:10.000 --> 00:27:14.999
have been carefully prepared.
00:27:15.000 --> 00:27:19.999
A place engineered beyond nature, where
monoculture has replaced biodiversity.
00:27:20.000 --> 00:27:24.999
It’s an ecology totally
dependent on the whim of men.
00:27:25.000 --> 00:27:33.000
[music]
00:27:35.000 --> 00:27:39.999
It’s called the Central
Valley of California.
00:27:40.000 --> 00:27:44.999
At the end of February when
every flower of 700,000 acres
00:27:45.000 --> 00:27:49.999
of blooming almond trees needs pollination.
00:27:50.000 --> 00:27:54.999
Over 36 billion bees are needed.
00:27:55.000 --> 00:27:59.999
It’s the world’s largest
seasonal animal migration.
00:28:00.000 --> 00:28:04.999
Without bees, wind pollination produces
about 40 pounds of nuts per acre.
00:28:05.000 --> 00:28:09.999
With bee pollination, they produce
3,000 pounds per acre, 60 times more.
00:28:10.000 --> 00:28:14.999
80% of the world’s almonds grow here.
00:28:15.000 --> 00:28:19.999
If you look at almonds in California,
00:28:20.000 --> 00:28:24.999
that’s the biggest story there is.
00:28:25.000 --> 00:28:29.999
Umm… Right now half of the colonies in the country
get moved to California for the almond pollination.
00:28:30.000 --> 00:28:34.999
By 2012, we expected 86%
of present day number,
00:28:35.000 --> 00:28:39.999
colonies to move into California for pollination. Now
if the number of cars decreases at the present rate,
00:28:40.000 --> 00:28:44.999
then every colony in the country conceivably
would need to be in California for pollination.
00:28:45.000 --> 00:28:49.999
You know, almonds makes more money for the
California economy than grapes and wine do.
00:28:50.000 --> 00:28:54.999
And so there is that need,
that real need for those bees.
00:28:55.000 --> 00:28:59.999
How do almond grow, where
they get the bees they need?
00:29:00.000 --> 00:29:04.999
They place a call to a cramped and
cluttered office on a side street
00:29:05.000 --> 00:29:09.999
in Bakersfield, California, where Joe Traynor
has spent 40 years putting beekeepers
00:29:10.000 --> 00:29:14.999
and Orchard owners together.
Joe Traynor is a bee broker.
00:29:15.000 --> 00:29:19.999
Oh, yeah, Frank… here Joe.
When I started in 1960s,
00:29:20.000 --> 00:29:24.999
there was enough bees in California to take care of
the entire, which was about 100,000 at that time
00:29:25.000 --> 00:29:29.999
and the rental fees for bees at
that time was about $3 a colony.
00:29:30.000 --> 00:29:34.999
But since the acreage expanded,
650,000 bearing acres now.
00:29:35.000 --> 00:29:39.999
There’s not enough bees in California to handle
that, so we get bees from all over United States
00:29:40.000 --> 00:29:44.999
and it’s the transportation cost of
bringing those bees out to California,
00:29:45.000 --> 00:29:49.999
it’s driven the price up, it’s…it’s
anywhere $138 to $200 rental fee now.
00:29:50.000 --> 00:29:54.999
Joe Traynor promises beekeepers
00:29:55.000 --> 00:29:59.999
a good price for the rental of their hives and promises
growers strong hives for efficient pollination.
00:30:00.000 --> 00:30:04.999
[sil.]
00:30:05.000 --> 00:30:09.999
My job is to put the bee in prosperities
path. My job is to identify
00:30:10.000 --> 00:30:14.999
where she will do best. So I have to kind of think like
bee. I have to think about the resources available and…
00:30:15.000 --> 00:30:19.999
and… In pollination work
it’s… it’s a contract.
00:30:20.000 --> 00:30:24.999
So I’m guided by revenue,
enhancing the revenue.
00:30:25.000 --> 00:30:29.999
Like you can hear it.
00:30:30.000 --> 00:30:34.999
Can you hear it? For John Miller,
00:30:35.000 --> 00:30:39.999
the sound of bees is the sound money. And
we’re looking for flight, we’re looking for…
00:30:40.000 --> 00:30:44.999
I want to see what the dancing
ladies are doing here.
00:30:45.000 --> 00:30:49.999
Here, look at this bosom right here.
See this guy,
00:30:50.000 --> 00:30:54.999
he just opened and the pollen grains
are on the right on the, right on the,
00:30:55.000 --> 00:30:59.999
into the flowering parts. This guy is
yesterday’s blossom and it’s all set.
00:31:00.000 --> 00:31:04.999
See the difference between this and this.
The pollen’s been forged and gathered and…
00:31:05.000 --> 00:31:09.999
and stirred up by the honeybee as she
rummaging around on the blossom.
00:31:10.000 --> 00:31:14.999
John Miller is one of a handful of industrial
beekeepers who keep their bees in perpetual motion,
00:31:15.000 --> 00:31:19.999
traveling thousands of
miles to pollinate crops
00:31:20.000 --> 00:31:24.999
all over the country. Some years we do
better in the pollination business,
00:31:25.000 --> 00:31:29.999
we’ll make an income off the almonds.
00:31:30.000 --> 00:31:34.999
Some of the bees then go to Washington State
for the apples. So we have opportunity
00:31:35.000 --> 00:31:39.999
to get two earnings centers but the apples
don’t pay nearly as good as the almonds.
00:31:40.000 --> 00:31:44.999
Then we go to the honey production in North Korea(ph).
Well, some years it’s dry and some years as wet,
00:31:45.000 --> 00:31:49.999
and some years it’s warm and some years it’s not
so warm, it’s farming. And you roll the dice.
00:31:50.000 --> 00:31:54.999
Every year you got to be comfortable
with a lot of risk, its farming.
00:31:55.000 --> 00:31:59.999
You know, some years are good
and some years are terrible.
00:32:00.000 --> 00:32:04.999
But even a good year can be terrible for the
bees. There’s stresses of moving, reorientation,
00:32:05.000 --> 00:32:09.999
sudden changes in diet and climate,
infestations, medications,
00:32:10.000 --> 00:32:14.999
the bees have no chance to adapt. We
have to push these hives and we know it.
00:32:15.000 --> 00:32:19.999
You know, it’s the middle of winter out here and we’re trying
to get those hives to where they’re just busting with bees
00:32:20.000 --> 00:32:24.999
because they then have the
strength and numbers,
00:32:25.000 --> 00:32:29.999
the capability to launch a big flight
into a big concentration of flowers
00:32:30.000 --> 00:32:34.999
because these trees all
bloom at the same time.
00:32:35.000 --> 00:32:39.999
Bingo, baby.
00:32:40.000 --> 00:32:44.999
A migrant beekeeper
00:32:45.000 --> 00:32:49.999
can make 75% of his income in just
three weeks of almond pollination.
00:32:50.000 --> 00:32:54.999
But to do so, means pushing
his bees without limit.
00:32:55.000 --> 00:32:59.999
As we’re maintaining the hives, when we find a hive
that’s substandard or the queen is failing or missing.
00:33:00.000 --> 00:33:04.999
We find the old queen, we kill her
00:33:05.000 --> 00:33:09.999
and add brood or eggs from another hive, add a
new way to do that hive, so we don’t lose it.
00:33:10.000 --> 00:33:14.999
With over 600 million bees,
00:33:15.000 --> 00:33:19.999
Ron Spears is one of the largest
beekeepers in the world.
00:33:20.000 --> 00:33:24.999
Maybe 7 to 10 years ago you could pretty much get two seasons
out of them. With the miticides that were putting in the hives,
00:33:25.000 --> 00:33:29.999
the constant movement of the
hives and the long season
00:33:30.000 --> 00:33:34.999
that the queen continues to laid, you know,
up to 10 or even 11 months in some cases.
00:33:35.000 --> 00:33:39.999
The queens just get wore out. Umm… They… It’s… it’s
stock just like horses or cattle or anything else and…
00:33:40.000 --> 00:33:44.999
and they lose their ability to lay umm… you
know, the 1500-2000 eggs that they need…
00:33:45.000 --> 00:33:49.999
need to lay every day to sustain
a strong colony of bees.
00:33:50.000 --> 00:33:54.999
She’s up against the screen facing them.
00:33:55.000 --> 00:33:59.999
She cannot survive without
worker bees around her.
00:34:00.000 --> 00:34:04.999
Ron Spears buys queens from Hawaii,
00:34:05.000 --> 00:34:09.999
seven to eight thousand per year.
00:34:10.000 --> 00:34:14.999
With industrial pollination,
00:34:15.000 --> 00:34:19.999
the honeybees intimate relationship with
place and season is irrevocably broken.
00:34:20.000 --> 00:34:24.999
The vast monocultures say pollinate our
femoral and artificial landscapes.
00:34:25.000 --> 00:34:33.000
[sil.]
00:34:35.000 --> 00:34:39.999
Even in the midst of plenty,
bees can die of starvation.
00:34:40.000 --> 00:34:44.999
In a natural environment,
00:34:45.000 --> 00:34:49.999
many plants flower at the same time
providing a rich variety of pollens
00:34:50.000 --> 00:34:54.999
with many nutrients.
00:34:55.000 --> 00:34:59.999
But here, bees have little choice.
00:35:00.000 --> 00:35:04.999
There’s but a single pollen.
00:35:05.000 --> 00:35:09.999
Monoculture of the scale
00:35:10.000 --> 00:35:14.999
is frequent these days in American farming.
00:35:15.000 --> 00:35:19.999
Is possible, it’s a problem, especially if
there’s micronutrients that are at low levels
00:35:20.000 --> 00:35:24.999
or absent from that
particular diet of bees,
00:35:25.000 --> 00:35:29.999
pollen of the bee. There can be deficiency
00:35:30.000 --> 00:35:34.999
and so that requires a whole new management
scheme of feeding good quality protein fat,
00:35:35.000 --> 00:35:39.999
vitamins, minerals. That’s a whole
new way of managing colonies,
00:35:40.000 --> 00:35:44.999
were becoming more and
more like a pig farmer,
00:35:45.000 --> 00:35:49.999
a chicken farmer, in that we’re
supplying the diet to the animals,
00:35:50.000 --> 00:35:54.999
we’re not, we’re just turning these
animals loose into the wild and…
00:35:55.000 --> 00:35:59.999
and expecting them to pick up adequate
nutrition, we’re now having to think more like
00:36:00.000 --> 00:36:04.999
a normal livestock person. His is a
high that’s already been treated
00:36:05.000 --> 00:36:09.999
and this is a nutritional patty, this is a bag of
menthol and this is highland, which is an antibiotic.
00:36:10.000 --> 00:36:14.999
Would pretends to be science
at the service of the bee,
00:36:15.000 --> 00:36:19.999
is really science at the service of
a system that works bees to death.
00:36:20.000 --> 00:36:24.999
If the bees have to be fed and medicated, it’s
because they’ve been brought into an environment
00:36:25.000 --> 00:36:29.999
they can never adapt to, they’ve been
tricked, their instincts used against them.
00:36:30.000 --> 00:36:34.999
You have to feed them to stimulate
them, to get them to strength.
00:36:35.000 --> 00:36:39.999
If you don’t stimulate and prior to the bloom coming on,
then they aren’t strong enough by the bloom does come on,
00:36:40.000 --> 00:36:44.999
they get strong towards the end of the bloom
but not at the beginning of the bloom.
00:36:45.000 --> 00:36:49.999
They are just totally
different type of beekeeping
00:36:50.000 --> 00:36:54.999
and I don’t hold it against them, and
that is the nature of the business
00:36:55.000 --> 00:36:59.999
and every step that that’s taken
along that line, invites trouble.
00:37:00.000 --> 00:37:04.999
I wouldn’t like to be involved.
It’s not beekeeping
00:37:05.000 --> 00:37:09.999
and it’s just a minefield,
you know, sad really, uh…
00:37:10.000 --> 00:37:14.999
All the squelches of the
bee are assembled here.
00:37:15.000 --> 00:37:19.999
Parasites and viruses are bound. The
rhythm of the seasons has been broken.
00:37:20.000 --> 00:37:24.999
The earth is saturated with pesticides
and fungicides and chemical fertilizers.
00:37:25.000 --> 00:37:29.999
It’s a hell for bees.
00:37:30.000 --> 00:37:34.999
It was among large migrant beekeepers that
Colony Collapse Disorder first appeared,
00:37:35.000 --> 00:37:39.999
aggressive management in a terribly degraded
environment are among the interacting factors
00:37:40.000 --> 00:37:44.999
many scientists point to is likely causes.
00:37:45.000 --> 00:37:49.999
Beekeepers know that colonies
can simply lose morale and die.
00:37:50.000 --> 00:37:54.999
[music]
00:37:55.000 --> 00:37:59.999
I can’t do without the almonds financially,
00:38:00.000 --> 00:38:04.999
but I think this place is, it’s toxic.
00:38:05.000 --> 00:38:09.999
It’s just amazing that they can take
those extremes and still be alive.
00:38:10.000 --> 00:38:14.999
The Central Valley of California
00:38:15.000 --> 00:38:19.999
is a landscape so extreme, as to
almost seeing another planet.
00:38:20.000 --> 00:38:24.999
But bees live in nightmare in
much more familiar landscapes,
00:38:25.000 --> 00:38:29.999
like the gently rolling
hills of Southwest Germany.
00:38:30.000 --> 00:38:34.999
In May 2008, in Bade-Wurttemberg,
00:38:35.000 --> 00:38:39.999
machines planting corn seeds raised a cloud of dust
from the dry earth. The dust carried pesticide
00:38:40.000 --> 00:38:44.999
scraped off the treated seeds.
It’s settled on apple blossoms
00:38:45.000 --> 00:38:49.999
and flowering canola fields
over an area of 125 miles.
00:38:50.000 --> 00:38:54.999
Eleven thousand five hundred
honeybee colonies destroyed,
00:38:55.000 --> 00:39:00.000
330 million bees.
00:39:30.000 --> 00:39:34.999
Christoph Koch is one of
700 beekeepers affected.
00:39:35.000 --> 00:39:39.999
He lost 70% of his bees.
00:39:40.000 --> 00:39:44.999
The culprit was Poncho pro, a pesticide
based on the activation Clothianidin.
00:39:45.000 --> 00:39:49.999
It earns €237 million per year for
the German chemical giant Bayer.
00:39:50.000 --> 00:39:54.999
Poncho pro is painted on the seeds of corn
00:39:55.000 --> 00:39:59.999
rather than spray it on the growing plant.
The treatment was recommended
00:40:00.000 --> 00:40:05.000
by the regional minister of
agriculture, Peter Hauk.
00:40:45.000 --> 00:40:49.999
Everything seemed very clear, a simple accident.
But in the analysis by the National Laboratory,
00:40:50.000 --> 00:40:54.999
be showed doses of Clothianidin well
below the official lethal level.
00:40:55.000 --> 00:41:03.000
Clothianidin residue
00:41:10.000 --> 00:41:14.999
was found in wax and pollen. And
the German Food Safety Authority
00:41:15.000 --> 00:41:19.999
took the extraordinary precautionary step of
suspending permission for (inaudible) treatment
00:41:20.000 --> 00:41:24.999
and corn and canola. They
are compensated beekeepers,
00:41:25.000 --> 00:41:29.999
€2 million for their losses
without admitting fault.
00:41:30.000 --> 00:41:34.999
Nothing more was covered about the
unexpected findings in the Toxicology Lab.
00:41:35.000 --> 00:41:39.999
But on the other side of the border,
French beekeepers are certain
00:41:40.000 --> 00:41:45.000
that this new family of pesticides to
kill bees and not just by accident.
00:42:05.000 --> 00:42:09.999
Starting in 1994, French beekeepers found
their babies dying in disappearing
00:42:10.000 --> 00:42:14.999
around the sunflower bloom.
Honey harvest dropped by 60%.
00:42:15.000 --> 00:42:19.999
Something had changed.
00:42:20.000 --> 00:42:24.999
That same year, Bayer introduced a new system
of pesticide for sunflowers and corn, Gaucho,
00:42:25.000 --> 00:42:29.999
it would become its best selling pesticide
ever with €556 million per year.
00:42:30.000 --> 00:42:34.999
Beekeepers fought to
have the product banned,
00:42:35.000 --> 00:42:39.999
the battle raged for years.
00:42:40.000 --> 00:42:44.999
[music]
00:42:45.000 --> 00:42:49.999
Gaucho was a neonicotinoid systemic
pesticide like Poncho Pro.
00:42:50.000 --> 00:42:54.999
A small dose is painted on the seeds and spread
through the body of the plant as it grows.
00:42:55.000 --> 00:42:59.999
Bayer claimed that the product
had no effect on bees,
00:43:00.000 --> 00:43:04.999
the active agent metoclopramide
didn’t contaminate pollen or nectar.
00:43:05.000 --> 00:43:09.999
[music]
00:43:10.000 --> 00:43:14.999
But French researchers found toxic
residue in sunflower nectar and pollen.
00:43:15.000 --> 00:43:19.999
And in lab studies, doses as small as three
parts per billion affected the bees.
00:43:20.000 --> 00:43:24.999
Faced with contradictions,
00:43:25.000 --> 00:43:30.000
the Ministry of Agriculture suspended
Gaucho on the principle of precaution.
00:44:10.000 --> 00:44:14.999
But pollen and nectar are
not the only plant products
00:44:15.000 --> 00:44:19.999
contaminated by treatment
with neonicotinoids.
00:44:20.000 --> 00:44:24.999
In 2009, Italian researchers found
that corn grown from treated seeds,
00:44:25.000 --> 00:44:29.999
exudes a lethal dose of
pesticide in quotation water,
00:44:30.000 --> 00:44:34.999
a sort of sap. The drops can be
up to thousand times more toxic
00:44:35.000 --> 00:44:39.999
than the dosage found in nectar. Bees to
drink the water die in a few minutes.
00:44:40.000 --> 00:44:44.999
[sil.]
00:44:45.000 --> 00:44:49.999
Bayer counters that there is no proof that bees
come in contact with quotation water in the wild.
00:44:50.000 --> 00:44:54.999
And they claim, the laboratory
experiments no matter how spectacular,
00:44:55.000 --> 00:44:59.999
cannot reproduce what happens in the field.
00:45:00.000 --> 00:45:04.999
Fringe toxicologists look bell zones,
00:45:05.000 --> 00:45:09.999
was on the scientific committee
that studied the effects of Gaucho,
00:45:10.000 --> 00:45:14.999
he’s been testing the latest generation
of pesticides for over 15 years.
00:45:15.000 --> 00:45:19.999
He’s made the disturbing discovery
00:45:20.000 --> 00:45:24.999
that neonicotinoids induce different
effects at different dosages,
00:45:25.000 --> 00:45:29.999
even extremely low repeated exposure
can have strong unexpected effects.
00:45:30.000 --> 00:45:35.000
With these insecticides,
there is no safe dose.
00:46:30.000 --> 00:46:34.999
Sub lethal intoxication causes
nervous disorders, loss of memory,
00:46:35.000 --> 00:46:39.999
or temporary paralysis.
Catastrophic for honeybees
00:46:40.000 --> 00:46:44.999
and wild bees are alike. Is sub lethal insecticide
poisoning the root cause of disappearing bees?
00:46:45.000 --> 00:46:49.999
Maryann Frazier’s long
series of field studies
00:46:50.000 --> 00:46:54.999
showed that bees are continuously
exposed to many agricultural chemicals
00:46:55.000 --> 00:46:59.999
and it’s not just adult
bees that are affected.
00:47:00.000 --> 00:47:04.999
So the struggle in the beginning was,
are these things out there to monitor?
00:47:05.000 --> 00:47:09.999
Are the bee, are the pesticides they are now, they are getting into the
hive, into the bees, food into the wax where the bees are developing,
00:47:10.000 --> 00:47:14.999
that was our original question, that question
has been answered. Yes, they are there,
00:47:15.000 --> 00:47:19.999
they are getting into the hive. In some pollen
samples we found as many as 31 different pesticides,
00:47:20.000 --> 00:47:24.999
on average we find six
pesticides per pollen sample.
00:47:25.000 --> 00:47:29.999
It turns out honeybees are quite good monitors of the environment.
They pretty much pick up everything that’s out there.
00:47:30.000 --> 00:47:34.999
And while we think we put these things out there
and they go away, obviously that’s not the case.
00:47:35.000 --> 00:47:39.999
The honeybee genome revealed that
00:47:40.000 --> 00:47:44.999
just as bees are weak in immunity genes,
they are weak and detoxification genes.
00:47:45.000 --> 00:47:49.999
They have few defenses against pesticides.
00:47:50.000 --> 00:47:54.999
The interactions of different
chemicals found in the environment
00:47:55.000 --> 00:47:59.999
are a danger of unknown dimension for
bees everywhere, both wild and domestic.
00:48:00.000 --> 00:48:04.999
We have the evidence that these pesticides,
the beginning evidence that show that
00:48:05.000 --> 00:48:09.999
these pesticides in combination
have a synergistic toxic effect.
00:48:10.000 --> 00:48:14.999
So two or three pesticides they have
together in a pollen diet for the bees
00:48:15.000 --> 00:48:19.999
have an additive… There’s an
additive effect of those pesticides.
00:48:20.000 --> 00:48:24.999
But we’re finding that these things, particularly
some fungicides and pesticides can synergize.
00:48:25.000 --> 00:48:29.999
Meaning that they can be much… much
more toxic when they’re added together
00:48:30.000 --> 00:48:34.999
than either of these two things
are on their own or additively.
00:48:35.000 --> 00:48:39.999
In the fall of 2009, at Apimondia,
the World Bee Congress.
00:48:40.000 --> 00:48:44.999
The role of pesticides remained
controversial. But in the corridors,
00:48:45.000 --> 00:48:49.999
news was circulating about a breakthrough
study demonstrating a new type of synergy.
00:48:50.000 --> 00:48:54.999
The author was Jeff Pettis of the United
States Department of Agriculture,
00:48:55.000 --> 00:48:59.999
his co-author Dennis van Engelsdorp.
00:49:00.000 --> 00:49:04.999
We exposed whole colonies to very low levels of neonicotinoids
in this case and then challenged bees from those colonies
00:49:05.000 --> 00:49:09.999
with no eczema, a pathogen, the gut
pathogen and we saw an increase.
00:49:10.000 --> 00:49:14.999
Even if we fed the pesticide at very low levels,
we saw an increase in those eczema levels
00:49:15.000 --> 00:49:19.999
in direct response to the low level feeding
of neonicotinoids as compared to the…
00:49:20.000 --> 00:49:24.999
once they were fed normal protein.
You measure that effect at levels
00:49:25.000 --> 00:49:29.999
that you could not detect the pesticides. And so that brings up
the question if… if it’s having an effect at that low doses,
00:49:30.000 --> 00:49:34.999
we wouldn’t have discovered in our study
because it was below the limit of detection.
00:49:35.000 --> 00:49:39.999
The only reason we knew the bees had
exposure was because we expose them,
00:49:40.000 --> 00:49:44.999
otherwise we wouldn’t never have known they were exposed.
The take-on messages that interactions may be the key.
00:49:45.000 --> 00:49:49.999
So in this case we’re… we’re
manipulating one pesticide
00:49:50.000 --> 00:49:54.999
in one pathogen and we clearly
see the interactions.
00:49:55.000 --> 00:49:59.999
The conclusions of Pettis and Van Engelsdorp were confirmed
in a lab study by French researchers by Yves le Conte
00:50:00.000 --> 00:50:04.999
and Luc Belzunces, published
in December 2009.
00:50:05.000 --> 00:50:09.999
Even at undetectable levels,
neonicotinoid pesticides,
00:50:10.000 --> 00:50:14.999
we can be immunity.
00:50:15.000 --> 00:50:19.999
If this is the final answer
to worldwide bee deaths,
00:50:20.000 --> 00:50:24.999
than the elimination or reduction of
neonicotinoids might save the bees.
00:50:25.000 --> 00:50:29.999
[music]
00:50:30.000 --> 00:50:34.999
Or is it too late? How can pesticides
had poison at undetectable levels
00:50:35.000 --> 00:50:39.999
be quantified or controlled? How can
their elimination be confirmed?
00:50:40.000 --> 00:50:44.999
Industrial agriculture
requires billions of bees
00:50:45.000 --> 00:50:49.999
but bees can’t live in the environments
that industrial agriculture produces.
00:50:50.000 --> 00:50:54.999
What choices there and who
will make the choice?
00:50:55.000 --> 00:50:59.999
For the moment the answer is simple,
00:51:00.000 --> 00:51:04.999
disposable bees. But science and industry
are already working on the future
00:51:05.000 --> 00:51:09.999
looking ahead to a world without bees.
00:51:10.000 --> 00:51:14.999
It’s possible to identify forms of genes
00:51:15.000 --> 00:51:19.999
that would confers uh…specific
sorts of advantages and then
00:51:20.000 --> 00:51:24.999
umm… use genetic engineering
to put those forms of genes
00:51:25.000 --> 00:51:29.999
umm… into bees. Now of course this
is a very young science, number one.
00:51:30.000 --> 00:51:34.999
And number two, uh… we have to be
very careful with this approach
00:51:35.000 --> 00:51:39.999
because we know that any
gene has multiple functions.
00:51:40.000 --> 00:51:44.999
There is no gene that just does one thing.
00:51:45.000 --> 00:51:49.999
The tools are there to produce bees that will be
more productive in our agricultural situations
00:51:50.000 --> 00:51:54.999
but we need to proceed very carefully.
00:51:55.000 --> 00:51:59.999
[sil.]
00:52:00.000 --> 00:52:04.999
There are possibilities for
technological solutions
00:52:05.000 --> 00:52:09.999
for some mechanical means of
providing pollination services.
00:52:10.000 --> 00:52:14.999
There may be umm… even robotic bees design
if you go far enough in the future.
00:52:15.000 --> 00:52:19.999
So I think we have not really exploited the technological
possibilities. We really have neglected pollination services
00:52:20.000 --> 00:52:24.999
and I think both biologically and technology,
many… many options are open to us
00:52:25.000 --> 00:52:29.999
and they just require development.
00:52:30.000 --> 00:52:38.000
[music]
00:53:00.000 --> 00:53:04.999
One of the biggest problems
we face in the world
00:53:05.000 --> 00:53:09.999
is that in my view and that of a lot of other scientists, we’ve
gone down some wrong roads in our agricultural technology,
00:53:10.000 --> 00:53:14.999
particularly in over intensification
00:53:15.000 --> 00:53:19.999
and spreading very uniform, genetically
uniform crops over too much of the planet
00:53:20.000 --> 00:53:24.999
and not looking at the genetic diversity of crops and
over-using artificial fertilizers and pesticides
00:53:25.000 --> 00:53:29.999
in ways that have just
made our problems worse.
00:53:30.000 --> 00:53:34.999
The biggest ecological damage done by
humanity overall is through agriculture.
00:53:35.000 --> 00:53:39.999
Miners once carried occasion Canary
00:53:40.000 --> 00:53:44.999
when they descended into the earth. The
death of the bird warned the miners
00:53:45.000 --> 00:53:49.999
that the atmosphere was dangerous.
00:53:50.000 --> 00:53:54.999
Bees are much more sensitive to environmental poisons
and humans they to act is environmental sentinels.
00:53:55.000 --> 00:53:59.999
[music]
00:54:00.000 --> 00:54:04.999
In the mines, when the canary died
00:54:05.000 --> 00:54:09.999
the miners evacuated. Today,
beekeepers and their bees
00:54:10.000 --> 00:54:14.999
are fleeing into cities to
escape famine and disease.
00:54:15.000 --> 00:54:20.000
[music]
00:54:45.000 --> 00:54:49.999
[sil.]
00:54:50.000 --> 00:54:54.999
On (inaudible) La Grave, “As bees
flee hame wi’ lades o’ treasure,
00:54:55.000 --> 00:54:59.999
The minutes wing’d their way wi’ pleasure.”
These were words of Robert Burns.
00:55:00.000 --> 00:55:04.999
”As bees flee hame wi’ lades o’ treasure,
00:55:05.000 --> 00:55:09.999
The minutes wing’d their way wi’
pleasure.” That was a reference to
00:55:10.000 --> 00:55:14.999
uh… bees being used for, as a therapeutic
00:55:15.000 --> 00:55:19.999
uh… medicine for old people and people who are
recuperating and they sat and watched the bees
00:55:20.000 --> 00:55:24.999
and the bees worked all day and that
people are happy to sit and watching them
00:55:25.000 --> 00:55:29.999
and the bees sting them because of a cottage hives, they were in
the gardens, you know, so they were used to people, you know.
00:55:30.000 --> 00:55:34.999
I mean, the country and
most beautiful countryside,
00:55:35.000 --> 00:55:39.999
not only am I looking after bees but I’m
interacting with people in the countryside.
00:55:40.000 --> 00:55:44.999
So it’s… it’s all about community
really and the countryside community
00:55:45.000 --> 00:55:49.999
and meeting people like shepherds and
farmers and landowners and that…
00:55:50.000 --> 00:55:54.999
As I see, we apply for, I’m the beekeeper
00:55:55.000 --> 00:55:59.999
and they have all their jobs has too. And it
would be a great pity if all those things
00:56:00.000 --> 00:56:04.999
eventually collapsed and went away.
00:56:05.000 --> 00:56:13.000
[sil.]
00:56:20.000 --> 00:56:24.999
There’s the queen look, isn’t that wonderful?
They fight, doesn’t like the exposure you know.
00:56:25.000 --> 00:56:29.999
Public arena.
00:56:30.000 --> 00:56:38.000
[sil.]
00:56:45.000 --> 00:56:53.000
