I only knew it was Earth Day because the Science and Discovery channel have been throwing out advertisements about special Sunday showings of Earth Day programs, some of them look pretty cool, but I'll be at work soon and will miss most of them.
Also has anyone been watching Planet Earth on Discovery Channel? It is a pretty awesome miniseries so far, completely shot in HD, so it looks really nice, took 4 or 5 years to make it and you can see the work that went into it. They showed this super slow motion shot of a crocodile taking down a wildebeast by the water, pretty fucking cool.
