Instances of environmental pollution by manufactured contaminants are widespread across the globe. Pesticides are commonly used in agriculture to combat pests, but can also harm other, non-targeted organisms.

One study showed this kind of disruptive effect across populations of American alligators (Alligator mississipiensis) that were exposed to a pesticide (DDT) spill in Lake Apopka, Florida. Surprisingly, another study in the same region showed a rebound in the population following their exposure, suggesting possible evolved resistance to pesticide contamination.Continue reading
