Endocrine Disruption

TEDX, the Endocrine Disruption Exchange, has a valuable page on pesticides and their dangers.  You can find it here: http://endocrinedisruption.org/pesticides/introduction
From TEDX: "Our particular concern about pesticides is that they have been designed to disrupt biological systems, causing death to target organisms, such as insects or plants. Some actually work by acting on the hormone systems of insects and plants.  The problem is that the biochemistry of most living things is similar enough that humans, wildlife and plants can also be adversely affected by pesticides."
