If you live on this planet you should see this documentary. This may seem a little silly and overstated, but it has become that urgent. It's easy to comprehend. It goes into enough detail to know that our planet is in trouble, without boring you or sounding like a lecture. You may not think the ocean current half way around the world has any effect on you, or the United States, but it does. This documentary explains weather patterns, the history of temperatures, earthquakes, ice ages. It explores the affect of pollution on the world, and the changes that are taking place right now. With great use of intelligence and humor, Al Gore does a great job bringing this topic to public attention. Don't think it's to late and unrealistic to change anything now. We can reverse some of the damage we have done. Watch. Learn how.
