THE WORLD WITHOUT US—Alan Weisman—Journalist Weisman for years researched the question of what would happen if humans suddenly disappeared from the earth and speculates/predicts the answers to that question. He treats geologic/geographic areas as well as the influences made or caused by humankind. His suggestions are based on past geologic/history, the anthropologic evidence of past civilizations, the effect and determination of flora and fauna and its adaptability to the circumstances in which he finds is. Particularly problematical seem to be plastic bags (plastic of about all kinds, petroleum and, not surprisingly, nuclear locations. He’s obvious he cares about both the earth and the human race inhabiting it, as well as present and extinct life forms. A frightening script on one hand and hopeful on the other.
