If you are decent human being who believes in doing the right thing, then this movie will either change how you think or reinvigorate your desire to act as a steward of Planet Earth. Everyone should see this movie. It should be broadcast on network TV every year/month/week, it should be shown to every school-age child. It should be shown to every city, state, county politician and every member of congress. Every CEO of every publicly-held corporation should be required to see it (and sign-off on seeing it as part of Sarbanes-Oxley (haha)). When it comes out on DVD, I will not buy a copy just for myself but many more copies for all my extended family members.
