Ages 7 to 14 years. Humans are sometimes to blame for catastrophic influences on the worlds air, water, soil, and natural resources. This book probes the causes and effects of greenhouse gases, acid rain, oil spills, air pollution, and other human-caused disasters. Topics include: the human activities that are causing the destruction of the ozone layer, and the results of this damage: ways that organisations such as Greenpeace and Pollution Probe try to prevent environmental disasters; methods used to recover from environmental disasters, such as re-planting forests, re-stocking formerly contaminated lakes, and the clean-up of chemical spills; the effects of environmental disasters on our natural resources, animals, plants, and humans; ways that scientists predict environmental disasters, and potential disasters that have been avoided as a result.
