An interesting and meticulously researched book for upper elementary and middle school children to learn about the life and lasting contribution of some of the world's greatest naturalists and environmentalists involved in the preservation of wild places. This book will positively influence the next generation to love our planet and work to protect it.
This book in the Earth Heroes series introduces eight historic and contemporary greats: Henry David Thoreau, whose writings formed the basis for the environmental movement; John Muir, the extraordinary naturalist; Theodore Roosevelt, who engaged the government in conservation; Aldo Leopold, instrumental in creating the world's first wilderness preserve; Richard St. Barbe Baker, who spearheaded the first major international reforestation campaign; Mardy Murie who worked to preserving huge wilderness tracts in Alaska; David Suzuki, eminent Canadian scientist and broadcaster; and Wangari Maathai, a Kenyan woman who focused on the social impact of the environment.

The "Earth Heroes" books feature the youth and careers of the world's greatest environmentalists, and the waves of influence that spread from their ideas and actions. This first in a series of three "Earth Heroes" books features such historic greats as John Muir and Aldo Leopold, as well as current luminaries such as David Suzuki and Maathai Wangari.
