The Gaia Theory - Prince William Conservation Alliance 1st Thursday Speaker Series February 4, 2010

Speaker: Martin Ogle, Chief Naturalist, Northern Virginia Regional Park Authority

The Gaia Theory is a scientific way to view the Earth as a single living system. It is taught as Earth System Science in many universities, but sometimes still dismissed as New Age religion by some.

Join Martin Ogle to learn about this tantalizing idea as he explains, in layman's terms, the science, history and societal implications of Gaia Theory.

How do oxygen and methane persist in stable concentrations in the atmosphere of the Earth? How have Carl Sagan, William Golding (author of "Lord of the Flies") and Vaclav Havel all contributed to the theory's development and use? How does Gaia Theory speak to global challenges ranging from climate change to energy use?

Join us on February 4 to learn more. Bring your questions and ideas!
