The Environmental Movement introduces readers to this significant movement, which arose in the United States in the late 1800s in response to the nation's dwindling forests and the pollution caused by a greater number of factories. The abundant photographs and vibrant text chronicles the accomplishments of conservationists such as Gifford Pinchot and John Muir, who helped the movement gain a foothold in the United States. This useful book also details how environmentalism has become a global effort, led by organizations such as Greenpeace and the World Wildlife Fund.
