Pesticide and Environmental Update
Bees: Victims
of Big Agriculture?
Over the past 30 years, honeybee populations
have plummeted 50%. Many factors are contributing to the decline- including
systemic pesticides, varroa mites and Nosema Disease- but the greatest
threat to the bee’s survival may be the industrial agriculture model that
promotes pesticides and monocropping.
When we read about “colony collapse
disorder,” we’re hearing about the problems confronting commercial
bee-brokers. Natural pollination by wild, resident honeybees and other
beneficial insects was the norm only 30 years ago. But natural pollination
is no longer possible where traditional habitats have been replaced by
weedless, laser-leveled acres planted to a single crop. In California’s
Central Valley, vast industrial spreads- artificially maintained by
synthetic nitrogen inputs, herbicides and insecticides—are no longer
hospitable to native bees, wasps, butterflies or other wildlife.
In May, following the mass deaths of bees and
other insects, Germany’s Office for Consumer Protection and Food Safety (BVL)
suspended use of eight pesticides after it was found that the bees were
killed by clothianidin, the active ingredient in Bayer’s Eldado and Poncho
pesticides. BVL also suspended use of four of Bayer’s imidacloprid-based
pesticides: Antarc, Chinook, Faibel and Gaucho. Products containing
neonicotinoids like imidacloprid and clothianidin account for much of Bayer’s
annual agrochemical profits. France’s Comité Scientifique et Technique
has declared the chemical a “significant risk” to bees.
As wild pollinators were increasingly forced
off the land, Big Ag turned to “domesticated” bees. When up to 90% of
U.S. commercial bee colonies went into a tailspin last winter, desperate
growers paid premium prices to air-freight one billion “guest worker”
bees from Australia to pollinate U.S. fields and orchards.
Commercial honeybees are the insect world’s
equivalent of migrant labor. Trucked thousands of miles from one field to
another, these bees are forbidden to forage on their own. They are only
released to service a particular crop—apples, peaches, oranges, melons—and
when they do, they are inevitably exposed to a range of chemical residues.
The U.S. Department of Agriculture has identified 58 pesticides that are “highly
toxic” to bees, including aldicarb, diazinon and malathion.
It might be more accurate to call commercial
colonies “prison colonies.” Trucked from state to state, these captive
bees are force-fed a diet of high fructose corn syrup and soy protein—a
poor substitute for pollen. This cheap, high-fiber, low-protein, junk-food
bee feed is derived from genetically modified corn that has been engineered
to contain Bt—a bacterial insecticide.
And now more of the honeybees’ native “homeland”
in the prairies of the Midwest—historic vistas of pollen-rich asters and
goldenrods—are set to be plowed under and monocropped to make corn ethanol
to fuel America’s automobiles.
There is an alternative. “This country has
4,500 species of native insects that are potential pollinators,” Gina
Covina writes in Terrain magazine. “On the East Coast, where farms are
much smaller, more diverse, and broken up by uncultivated land, native
insects account for up to 90% of crop pollination.” In Costa Rica, studies
have shown coffee yields increase 20% when crops are grown within a
kilometer of a forest. In Canada, canola yields increased on farms that
preserved 30% of the land as natural habitat.
“Fortunately,” Covina notes, “insects
are quick to recolonize formerly dead areas—hedgerows, windbreaks,
wetlands, woodlots.” But the survival of Earth’s bees will require a
fundamental transition from the industrial agriculture model to the
biodiverse ecological model.
