Where Have All the Honey Bees Gone?

Thursday, April 18th, 2013

Despite many years of observing and commenting on the human condition, I continue to be amazed (though no longer surprised) at the ignorance and arrogance (fellow travelers) we humans often display with regard to our own well-being. And no, I’m not talking about the Tea Party and its hostages in the Republican Party. At least not exclusively them.

Rather, I’m talking about the people who, in the name of commerce, science, progress, even good health, look upon nature as something to be improved upon, to be conquered, to be shown, in effect, who’s boss. The folks at Monsanto, who feel compelled to alter the genetic makeup of so much of the food we eat, are a prime example of this attitude. Growing more and hardier crops in smaller spaces means more profits, even though no one can say for certain that the science behind the profits will eventually prove to be safe for humans. Their arrogance bought the ignorance of a feckless Congress, which protected the company from revealing its GMOs on food labels.

But, I have another example of humans recklessly meddling with nature in mind here. We’re talking about honey bees, which are dying at a rate that cannot be good for the planet or those who live on it.

In fact, honey bees have been disappearing at an alarming rate for more than a decade. Some say a million colonies a year. Gone. No trace. It’s the kind of things most people don’t notice. After all, we‘re just talking about bees here, right? But those who grow fruits and vegetables depend on the bees for cross-pollination, the process that allows fertilization and productions of seeds. These food producers have been well aware of the growing bees crisis.

Last year, scientists said they believe they finally figured out the culprit — a group of pesticides known as neonicotinoids. Produced mainly by the chemical giant, Bayer, these pesticides are present in commonly used home gardening products and are regularly sprayed on millions of acres of corn, soy, wheat and cotton seeds in the United States alone.

Scientific reports say the insecticides act as a nerve poison, infecting the pollen and nectar of plants, disorienting the bees and making it impossible for them to find their way back to their hives. In addition, scientists believe aggressive land development and the destruction of natural bee habitats has added to the disappearance. Plus, some of those genetically modified organism crops have had toxic insecticides introduced into their genetic structure, in the name of making them hardier. But scientists think the toxins may also be poisoning the bees.

Here’s where the ignorance and arrogance come in. Do we want to depend on chemical giants like Monsanto and Bayer to guarantee a healthful supply of fruits and vegetables, or would we rather depend on the stewards nature provided — the honey bees? My money’s on the bees, but commercial beekeepers can’t compete with the money the chemical companies spend on gaining protection from state and federal government agencies. Still, the beekeepers last month sued the Environmental Protection Agency, asking it to remove its approval of two widely used neonicotinoids. (Germany and France have done so.) Bayer continues to insist they are safe. The EPA’s lukewarm response was to send a team to California, where millions of commercial hives are needed yearly, to talk about the problem.

Talk is cheap. The EPA, which relies on the chemical companies’ testing to determine the safety of their own products, needs to launch a full scale review of these pesticides, as well as the toxins spliced into crops, to determine if they are, in fact, killing off millions of bees and jeopardizing the bountiful food supply nature has provided without any help from humans. We would do well to listen to the warnings of the honey bees and the people who know how to work with and nurture them, rather than the profit-driven assurances of giant purveyors of better farming through chemicals.

If you care about the food you eat, write the EPA to take meaningful action, via their web site: epa.gov. Or, sign a petition at change.org: http://www.change.org/petitions/epa-save-our-bees-and-the-food-we-eat-ban-bayer-s-chemicals-now. Help the bees find their way home.

Don’t Attack Your Lawn with Pesticides

Wednesday, May 30th, 2012

By Shawn Dell Joyce

Who uses more pesticide, farmers or homeowners? According to a recent Virginia Tech study, homeowners commonly use up to ten times as much chemicals as farmers. According to the study, the pesticide application rates for farmers is 2.7 pounds per acre, while homeowners (and lawn care companies) slather on 3.2 to 9.8 pounds per acre.

Each year, homeowners apply an astonishing 90 million pounds of pesticides — at least — to their lawns and gardens, according to the Boston-based Toxics Action Center. In fact, homeowners represent the only growth sector of the U.S. pesticide market, as agricultural uses of these chemicals are declining. This market trend was started by the pesticide industry in an attempt to establish new markets for old products. That’s because most lawn pesticides were registered before 1972, and were never tested for many human health hazards like carcinogenicity, neurotoxicity, and environmental dangers.

Lawn chemical companies are still not required to list all the ingredients on their containers, which means risks still exist for home gardeners. Many toxins are hidden on the product label by being classified as “inert.” Inert does not mean “inactive” and in the case of benzene and xylene, can be even more toxic than the listed chemicals. Some of the listed chemicals include components of defoliants such as Agent Orange, nerve-gas type insecticides, and artificial hormones.

The blue meanies of lawn chemicals are 2,4-D, Captan, Diazinon, Dursban, Dacthal, Dicamba, and Mecocrop. These chemicals were registered without a full safety screening. A combination of several of these toxins is usually found on store shelves. 2,4-D is a hormone disruptor, Dursban concentrates in the environment, and Diazinon is an organophosphate which damages the nervous system.

Some of these chemicals have been banned for use on golf courses and sod farms due to massive water bird deaths, but are still widely used on lawns and gardens.

To be clear: Pesticides applied on lawns can be harmful to humans who inhale them, ingest them, or absorb them through skin contact. These chemicals also get tracked into our houses on our shoes and pets. An Environmental Protection Agency study found outdoor pesticide loads build up in carpets and can remain there for years, where they do not degrade from exposure to sunlight or rain.

This leaves our pets and children most vulnerable, as they most frequently play on lawns and carpets, and breathe in toxins. The Toxic Action Center report notes that “children’s internal organs are still developing and maturing and their enzymatic, metabolic, and immune systems provide less natural protection than those of an adult.” Researchers caution that children are most vulnerable in the fetal and adolescent stages when “chemical exposures can permanently alter future development.”

The EPA’s risk assessments indicate that home lawn care products account for 96 percent of the risk associated with using this chemical for women of childbearing age, and that anticipated doses are “very close to the level of concern.” EPA studies found that rats exposed to the most common lawn chemical (2,4-D) in utero showed an increased incidence of skeletal abnormalities, such as extra ribs and malformed ribcages. In rabbits, 2,4-D and its diethanolamine salt caused abortion, skeletal abnormalities, as well as developmental neurotoxicity and endocrine disruption.

Even though many lawn chemicals are legal, and widely available, that doesn’t equal “safe,” even though some lawn chemicals may advertise “safe” on the label. The EPA fined Dow Elanco for “failing to report to the agency information on adverse health effects (to humans) over the past decade involving a number of pesticides,” including Dursban.

The concern that certain widely used lawn chemicals can cause birth defects has prompted California to require that consumers are informed about these risks. California’s Office of Environmental Health Hazard Assessment announced its intention to list the herbicide 2,4-D and related compounds as developmental toxicants under California’s Safe Drinking Water and Toxic Enforcement Act. Ontario and other Canadian governments have moved to similarly ban toxic lawn chemicals.

How can you help avoid the risks?

  • Participate in the National Wildlife Federation Backyard Wildlife Habitat program. www.nwf.org/backyard/
