Did you know that a quarter of all mammals, half of all insects and reptiles, and nearly three-quarters of all flowering plants are endangered? Some scientists predict that, if we do nothing, half of all species alive today will be extinct by 2100. This book looks at the many animals and plants that have become endangered through hunting, poaching, pollution, habitat loss, and climate change. It also discusses the steps conservationists are taking to protect threatened species.
Each of these books examines a potential crisis, its historical causes, scientific background, and possible outcome if no action is taken. AIDS discusses the possibility of worldwide pandemics of influenza and other infectious diseases such as SARS, malaria, and meningitis. In discussing the prevention of AIDS, the author mentions abstinence and safe sex without explanation, while the case of Ryan White, who contracted the disease from a transfusion as a child, is given thorough coverage. Fuels makes the connection between climate change and the use of polluting energy sources, and the Kyoto Protocol's plans for the reduction of globe-warming emissions are considered. Overcrowded World cites many problems such as shortages of water, food, and housing; degradation of natural environments; and poverty. Family planning is mentioned only in passing while the consequences of high birth rates are more thoroughly discussed. Endangered Species , divided into sections by habitat, discusses declining and threatened animal, plant, and insect life due to global warming, habitat extinction, and overhunting and fishing. Each volume presents several potential scenarios for the year 2025 and a sidebar asks readers what they would do to solve or alleviate the urgent situations of the time, questions that could be used to spark class discussions. Full-color photographs, charts, and maps help illustrate some of the ideas and problems.-Eva Elisabeth VonAncken, Trinity-Pawling School, Pawling, NY
