Our world runs on energy - without it, things come to a screeching halt, as the recent hurricanes have shown. Ever stop to wonder what our energy future is? What are our options for energy, and what are the associated economic and climatic implications? In \Energy and the Environment\" we explore these questions, which together represent one of the great challenges of our time - providing energy for high quality of life and economic growth while avoiding dangerous climate change. This course takes an optimistic view of our prospects, and we'll see how shifting to renewable energy can lead to a viable future.

Geysers and grizzlies and glaciers, oh my. The national parks may be America's best idea, saving the finest parts of the nation for everyone to enjoy forever. What better way to learn about the natural world than to tour the parks with us? We'll explore how the mountains and valleys formed and why they often come with volcanoes and earthquakes. You'll see what really killed the dinosaurs and how we can help save their modern relatives in the parks. With film clips, slide shows, and our geological interpretations of classic rock songs, isn't it time for a road trip?
