Autism and Disappearing Bees: A Common Denominator?

"The brain of insects is the intended target of these insecticides.  They disrupt the bees homing behavior and their ability to return to the hive, kind of like “bee autism.”   But insects are different than humans, right?   Human and insect nerve cells share the same basic biologic infrastructure.  Chemicals that interrupt electrical impulses in insect nerves will do the same to humans.  But humans are much bigger than insects and the doses to humans are  miniscule, right?
During critical first trimester development a human is no bigger than an insect so there is every reason to believe that pesticides could wreak havoc with the developing brain of a human embryo.   But human embryos aren’t out in corn fields being sprayed with insecticides, are they?  A recent study showed that every human tested had the world’s best selling pesticide, Roundup, detectable in their urine at concentrations between five and twenty times the level considered safe for drinking water.
The autism epidemic and disappearing bees are real public health emergencies created by allowing our world to be overwhelmed by environmental toxins.  Environmental protection is human protection, especially for the smallest and most vulnerable among us."

More Damning Evidence Points to Pesticide as Cause of Mass Bee Deaths | Common Dreams

- Common Dreams staff

A new study published in Naturwissenschaften - The Science of Nature by a leading bee expert provides damning evidence that a widely used pesticide, even at low levels, is responsible for the recent catastrophic decline in honey bees. Dr. Jeff Pettis of the USDA's Bee Research Laboratory in Beltsville, MD led the study.
Colony collapse disorder, as this phenomenon is known, has been getting worse since 2006.
The news has brought renewed calls for these pesticides, which only became widely used in the 1990s, to be banned as honey bees are key to human’s survival – pollinating 70 per cent of the crops which produce most of the world’s food.
The pesticide that the study (pdf) looked at was imidacloprid, one of the most widely used pesticides worldwide. It is neonicotinoid insecticide produced by Bayer CropScience.

Decline of Honey Bees Now a Global Phenomenon, says United Nations

Decline of Honey Bees Now a Global Phenomenon, says United Nations
by Michael McCarthy

The mysterious collapse of honey-bee colonies is becoming a global phenomenon, scientists working for the United Nations have revealed.

Declines in managed bee colonies, seen increasingly in Europe and the US in the past decade, are also now being observed in China and Japan and there are the first signs of African collapses from Egypt, according to the report from the United Nations Environment Program (UNEP).

The authors, who include some of the world's leading honey-bee experts, issue a stark warning about the disappearance of bees, which are increasingly important as crop pollinators around the globe. Without profound changes to the way human beings manage the planet, they say, declines in pollinators needed to feed a growing global population are likely to continue. The scientists warn that a number of factors may now be coming together to hit bee colonies around the world, ranging from declines in flowering plants and the use of damaging insecticides, to the worldwide spread of pests and air pollution. They call for farmers and landowners to be offered incentives to restore pollinator-friendly habitats, including key flowering plants near crop-producing fields and stress that more care needs to be taken in the choice, timing and application of insecticides and other chemicals. While managed hives can be moved out of harm's way, "wild populations (of pollinators) are completely vulnerable", says the report.

"The way humanity manages or mismanages its nature-based assets, including pollinators, will in part define our collective future in the 21st century," said Achim Steiner, UN Under-Secretary-General and UNEP Executive Director.

"The fact is that of the 100 crop species that provide 90 per cent of the world's food, over 70 are pollinated by bees.

"Human beings have fabricated the illusion that in the 21st century they have the technological prowess to be independent of nature.

"Bees underline the reality that we are more, not less, dependent on nature's services in a world of close to seven billion people."

Declines in bee colonies date back to the mid 1960s in Europe, but have accelerated since 1998, while in North America, losses of colonies since 2004 have left the continent with fewer managed pollinators than at any time in the past 50 years, says the report.

Now Chinese beekeepers have recently "faced several inexplicable and complex symptoms of colony losses in both species", the report says. And it has been reported elsewhere that some Chinese farmers have had to resort to pollinating fruit trees by hand because of the lack of insects.

Furthermore, a quarter of beekeepers in Japan "have recently been confronted with sudden losses of their bee colonies", while in Africa, beekeepers along the Egyptian Nile have been reporting signs of "colony collapse disorder" – although to date there are no other confirmed reports from the rest of the continent.

The report lists a number of factors which may be coming together to cause the decline and they include:

* Habitat degradation, including the loss of flowering plant species that provide food for bees;

* Some insecticides, including the so-called "systemic" insecticides which can migrate to the entire plant as it grows and be taken in by bees in nectar and pollen;

* Parasites and pests, such as the well-known Varroa mite;

* Air pollution, which may be interfering with the ability of bees to find flowering plants and thus food – scents that could travel more than 800 meters in the 1800s now reach less than 200 meters from a plant.

"The transformation of the countryside and rural areas in the past half-century or so has triggered a decline in wild-living bees and other pollinators," said one of the lead authors, Dr Peter Neumann of the Swiss Bee Research Center.

"Society is increasingly investing in 'industrial-scale' hives and managed colonies to make up the shortfall and going so far as to truck bees around to farms and fields in order to maintain our food supplies.

"A variety of factors are making these man-made colonies vulnerable to decline and collapse. We need to get smarter about how we manage these hives, but perhaps more importantly, we need to better manage the landscape beyond, in order to recover wild bee populations."

Chemicals in Our Food, and Bodies

by Nicholas D. Kristof

Your body is probably home to a chemical called bisphenol A, or BPA. It's a synthetic estrogen that United States factories now use in everything from plastics to epoxies - to the tune of six pounds per American per year [1]. That's a lot of estrogen.
More than 92 percent [2] of Americans have BPA in their urine, and scientists have linked it - though not conclusively - to everything from breast cancer to obesity, from attention deficit disorder to genital abnormalities in boys and girls alike.
Now it turns out it's in our food.
Consumer Reports magazine tested [3] an array of brand-name canned foods for a report in its December issue and found BPA in almost all of them. The magazine says that relatively high levels turned up, for example, in Progresso vegetable soup, Campbell's condensed chicken noodle soup, and Del Monte Blue Lake cut green beans.
The magazine also says it found BPA in the canned liquid version of Similac Advance infant formula (but not in the powdered version) and in canned Nestlé Juicy Juice (but not in the juice boxes). The BPA in the food probably came from an interior coating used in many cans.
Should we be alarmed?
The chemical industry doesn't think so. Steven Hentges of the American Chemistry Council [4] dismissed the testing, noting that Americans absorb quantities of BPA at levels that government regulators have found to be safe. Mr. Hentges also pointed to a new study [5] indicating that BPA exposure did not cause abnormalities in the reproductive health of rats.
But more than 200 other studies have shown links between low doses of BPA and adverse health effects, according to the Breast Cancer Fund [6], which is trying to ban the chemical from food and beverage containers.
"The vast majority of independent scientists - those not working for industry - are concerned about early-life low-dose exposures to BPA," said Janet Gray, a Vassar College professor who is science adviser to the Breast Cancer Fund.
Published journal articles [7] have found that BPA given to pregnant rats or mice can cause malformed genitals in their offspring, as well as reduced sperm count among males. For example, a European journal found that male mice exposed to BPA were less likely to make females pregnant, and the Journal of Occupational Health found that male rats administered BPA had less sperm production and lower testicular weight.
This year, the journal Environmental Health Perspectives found that pregnant mice exposed to BPA had babies with abnormalities in the cervix, uterus and vagina. Reproductive Toxicology found that even low-level exposure to BPA led to the mouse equivalent of early puberty for females. And an array of animal studies link prenatal BPA exposure to breast cancer and prostate cancer.
While most of the studies are on animals, the Journal of the American Medical Association reported last year that humans with higher levels of BPA in their blood have "an increased prevalence of cardiovascular disease, diabetes and liver-enzyme abnormalities." Another published study found that women with higher levels of BPA in their blood had more miscarriages.
Scholars have noted some increasing reports of boys born with malformed genitals, girls who begin puberty at age 6 or 8 or even earlier, breast cancer in women and men alike, and declining sperm counts among men. The Endocrine Society, an association of endocrinologists, warned this year that these kinds of abnormalities may be a consequence of the rise of endocrine-disrupting chemicals, and it specifically called on regulators to re-evaluate BPA.
Last year, Canada became the first country to conclude that BPA can be hazardous to humans, and Massachusetts issued a public health advisory in August warning against any exposure to BPA by pregnant or breast-feeding women or by children under the age of 2.
The Food and Drug Administration, which in the past has relied largely on industry studies - and has generally been asleep at the wheel - is studying the issue again [8]. Bills are also pending [9] in Congress to ban BPA from food and beverage containers.
"When you have 92 percent of the American population exposed to a chemical, this is not one where you want to be wrong," said Dr. Ted Schettler of the Science and Environmental Health Network. "Are we going to quibble over individual rodent studies, or are we going to act?"
While the evidence isn't conclusive, it justifies precautions. In my family, we're cutting down on the use of those plastic containers that contain BPA to store or microwave food, and I'm drinking water out of a metal bottle now. In my reporting around the world, I've come to terms with the threats from warlords, bandits and tarantulas. But endocrine disrupting chemicals - they give me the willies.
