Optimistic Environmentalist [EPUB ebook] 
Progressing Toward a Greener Future

Yes, the world faces substantial environmental challenges — climate change, pollution and extinction. But the surprisingly good news is that we have solutions to these problems. In the past 50 years, a remarkable number of environmental problems have been solved, while substantial progress is ongoing on others. The Optimistic Environmentalist chronicles these remarkable success stories, from saving endangered species to creating national parks that conserve land and resources. A bright green future is not only possible, it’s within our grasp.
