In a new book, "The Skeptical Environmentalist," Bjorn Lomborg looks at the current state of the planet and takes issue with the many sensational claims made by the environmental movement over the years. Using data from government organizations such as the US EPA and the United Nations, he points out that in most areas, environmental quality is improving. People are living longer, healthier and more prosperous lives, which is contrary to what many of these groups would like us to believe.
