This deluxe Library of America volume presents one of the landmark books of the twentieth century together with rare letters, speeches, and other writings that reveal the personal courage and passionate commitment of its author, Rachel Carson. A huge bestseller when published in September 1962, Silent Spring led not only to many of the laws and government agencies that protect our air, land, and water, but prompted a revolution in environmental consciousness. Now for the first time, in previously unpublished and newly collected letters to biochemists, ecologists, cancer specialists, ornithologists, and other experts, Carson's groundbreaking expose of the unintended consequences of pesticide use comes together piece-by-piece, like a puzzle or detective story. She makes common cause with conservationists and other allies to build public awareness, hiding her private battle with cancer for fear it might distract from her message. And in the wake of her book's astonishing impact, as she becomes the target of an organized campaign of disinformation by the chemical industry, Carson speaks out in defense of her findings while remaining a model of grace under pressure. Throughout the collection, Carson's lifelong love of nature shines through. In writings both lyrical and intensely moving, she conveys her "sense of wonder" to her young nephew, dreams of conserving old-growth forest in Maine for posterity, and recounts her adventures and epiphanies as birdwatcher and beachcomber.
