Bjørn Lomborg, a former member of Greenpeace, challenges widely held beliefs that the world environmental situation is getting worse and worse in his new book, The Skeptical Environmentalist. Using statistical information from internationally recognized research institutes, Lomborg systematically examines a range of major environmental issues that feature prominently in headline news around the world, including pollution, biodiversity, fear of chemicals, and the greenhouse effect, and documents that the world has actually improved. He supports his arguments with over 2500 footnotes, allowing readers to check his sources.
