Dr. Art's Guide to Planet Earth book and website. We humans can dramatically change the way our planet works as a whole. Because of our technologies and large population, each of us in our daily lives can do things that together cause changes in the global climate, Earth's ozone shield, and its web of life. Is the situation hopeless? Is it all too hard to understand? No, no and no again. Dr. Art's Guide to Planet Earth provides a simple yet powerful way to understand how our planet works, and what we can do about today's global and local environmental issues.
