Bees, Bats, Frogs….Why are they going away?

An interesting story at the Yale environment360 project, looking at the three different mass die-offs (Amphibians, Bats and Bees) which might be connected by a common thread:

Behind Mass Die-Offs,
Pesticides Lurk as Culprit

In the past dozen years, three new diseases have decimated populations of amphibians, honeybees, and — most recently — bats. Increasingly, scientists suspect that low-level exposure to pesticides could be contributing to this rash of epidemics.

Ever since Olga Owen Huckins shared the spectacle of a yard full of dead, DDT-poisoned birds with her friend Rachel Carson in 1958, scientists have been tracking the dramatic toll on wildlife of a planet awash in pesticides. Today, drips and puffs of pesticides surround us everywhere, contaminating 90 percent of the nation’s major rivers and streams, more than 80 percent of sampled fish, and one-third of the nation’s aquifers. According to the U.S. Fish and Wildlife Service, fish and birds that unsuspectingly expose themselves to this chemical soup die by the millions every year.

Reminds me of Lem’s Chain of Chance, where several man-made compounds end up having a totally unforeseen effect, when combined.

Another piece of news that validates the precautionary principle:

Are Contaminants Silencing Our Genes?

By Bette Hileman and Environmental Health News Some chemicals may leave people vulnerable to diseases like cancer and diabetes, not by mutating genes but by turning them off or on at the wrong time

Each of us starts life with a particular set of genes, 20,000 to 25,000 of them. Now scientists are amassing a growing body of evidence that pollutants and chemicals might be altering those genes—not by mutating them, but by sending subtle signals that silence them or switch them on at the wrong times.
