Nick of Time: DDT and Raptors

Rachel Carson painted a world void of the sounds of insects and birds in her ground-breaking book Silent Spring, published in 1962. Millions were stunned to discover the deadly consequences of our increasing dependence on potent pesticides. Poisons like DDT slowly accumulated in each stage of the food chain, almost destroying some birds of prey like the Peregrine Falcon and Bald Eagle. Gerri Griswold will give a talk on the history of DDT and the amazing comeback of raptor species with the discontinuation of its use.
