Here is the inspiring account of ten men and women who dedicated their lives to protecting the nation’s natural heritage.  Who popularized birdwatching…or introduced the study of birds in North Amerca?  Who pushed a president and a nation into setting aside vast preserves of land? Who did the same for the Florida Everglades?  Who opened the world’s eyes to the dangers of pesticides?   Well known, and lesser known figures are included .  Interesting black and white photographs, sidebars, resource lists and a survey of environmental issues round out this topic.  The text is accessible to researchers, as well as leisure readers.  Twenty one activities, such as bird feeders, a compost pile, plaster casts of animals’ tracks, tests and studies of the greenhouse effect and acid rain connect students with hands-on learning.  Excellent Resources and Index in Back Matter. Lovely  publication!
