"Astrobiologist David Grinspoon, a consultant to NASA and the European Space Agency, will talk about his new book, Earth in Human Hands: Shaping Our Planet's Future. Grinspoon argues that our era is one of great potential as well as peril, and that we can overcome climate change and other threats if we learn to become "graceful planetary engineers." Bill Nye "The Science Guy" says, "If you have family and friends here on earth, read this book."
