"Forty years ago, Silent Spring delivered a galvanic jolt to public consciousness and, as a result, infused the environmental movement with new substance and meaning...It was Rachel Carson's achievement to synthesize this knowledge into a single image that everyone, scientists and the general public alike, could easily understand...We are still poisoning the air and water and eroding the biosphere, albeit less so than if Rachel Carson had not written. Today we understand better than ever why we must press the effort to save the environment all the way home, true to the mind and spirit of the valiant author of Silent Spring."
