The National Geographic Channel has an interesting show scheduled for this weekend that might be worth checking out. The Human Footprint will air on Sunday, April 13, 2008, at 9 p.m.
"Using science and revelatory visual events, NGC delivers an extraordinary personal audit of how much of the world's resources each of us consumes, illustrating the average American's human footprint."
You can also look at the Human Footprint website for interesting facts and videos. I actually had a hard time navigating their video section, but came across many other cool videos as I hunted for the one which initially caught my eye. For instance, they have a video called "LA Sewers" which gives a tour of the largest waste water treatment plant on the west coast. Cool!
