There's been two specials I've come across over the last few months dealing on what would happen to our little planet post humans. The first was on Discovery back in, I think January or February the other was on NatGeo the other night. After seeing them both, both which were great specials, I think I liked the NatGeo one better. It was a bit darker, talking about how our Nuclear Power plants would fail and it also talked about how relics on Luna would remain there for eternity. Anyone else catch these specials? What did you think of them if you did?
