Relyea has focused his efforts, over the past nine years, on investigating the connections between the global decline in amphibians, routine pesticide use, and its potentially adverse affects on humans. Amphibians are an environmental indicator species (enter the proverbial canary); their sensitivity to pollutants can hint at what's to come for other types of animals. The pesticides that Relyea used in his study are easily transferred, by wind and water, beyond their initial locations. While the EPA has set guidelines regarding human lifetime exposure to pesticides, testing and limit-setting have neglected to account for the natural processes by which materials move throughout and between ecosystems. Or, say, crop fields. Note to the public: the canary is dead, or at least looking worse for the wear. Amphibians are dropping like bees, and it's time we paid attention and demanded a higher standard of pesticide testing and regulation before it really is too late.
