Living Dangerously: The Earth, Its Resources, and the Environment [Book Review]

This is a book about Earth, the third planet from the Sun, and earth, the land surface of the world and home of humanity, in distinction from heaven and hell. I, along with the American Geophysical Union, the Geological Society of America and the authors of this book, use the capital letter to connote respect for a fragile and finite planet. The editors of American Scientist and some other publications, fewer each year, often use the lowercase letter, but all of us are talking about the geological object and the home of humankind.
