Food for thought: Rachel Carson on biological pest control
Silent Spring author describes US govt. method of biological pest control for eradication of houseflies, 1962:
“Scientists at the Department of Agriculture laboratory in Orlando, Florida, are now sterilizing the housefly in laboratory experiments and even in some field trials, using chemicals incorporated into suitable foods...A chemical sterilant... could be combined with a bait substance and introduced into the natural environment of the fly; insects feeding on it would become sterile and in the course of time the sterile flies would predominate and the insects would breed themselves out of existence.”
“The sterilants currently being tested fall generally into two groups, both of which are extremely interesting in their mode of action. The first are intimately related to the life processes, or metabolism of the cell; i.e. they so closely resemble a substance the cell or tissue needs that the organism ‘mistakes’ them for the true metabolite and tries to incorporate them in its normal building processes. But the fit is wrong in some detail and the process comes to a halt. Such chemicals are called anti-metabolites.”

Glyphosate acts as an estrogen, and operates via the same hormonal pathways as natural estrogen.
--Dr Mae Wan Ho, The Ecologist
“In binding to the estrogen receptor, BPA (in plastic) can disrupt the body's endocrine or hormone system, with consequences especially worrisome for fetuses, infants and young children. Earlier this year, the U.S. Food and Drug Administration banned BPA in baby bottles and sippy cups. Its use is more broadly banned elsewhere in the world (in all food packaging: France--ed.; Science Daily, Oct. 4, 2012)”
[Carson, cont.--:] “The second group consists of chemicals that act on the chromosomes (mutagens--ed.), probably affecting the gene chemicals and causing the chromosomes to break up. The chemosterilants of this group are alkylating agents, which are extremely reactive chemicals, capable of intense cell destruction, damage to chromosomes, and production of mutations.”

The insecticidal poison affects a generation once-removed from initial contact
“These important studies establish the fact that the insecticidal poison affects a generation once removed from initial contact with it. Storage of poison in the egg, in the yolk material that nourishes the developing [bird] embryo, is a virtual death warrant and explains why so many of DeWitt's birds died in the egg or a few days after hatching.” Silent Spring p116
