This is quite a piece of propaganda. Evil corporations, a malevolent government, nuclear weapons, ignorant insensitive humans...it's all here.

Bruce Dern and crew blast off on a gigantic spaceship loaded with the last remaining forest of a doomed Earth. Dern, as the main character, actually murders his crew mates, but that's okay because he's saving a forest. Later in the movie, he notices that the forest is dying and he can't figure out why. After he killed everyone and faked a ship malfunction, he flew out into deep space. Gee whiz! Turns out the Sun isn't as strong in deep space. Duh! I thought this guy was a scientist.

I managed to stay with this movie until Dern is laying in bed then reaches his hand out to gently caress the "Conservation Pledge" hanging on his wall. I understand the importance of the Earth's ecosystem but this movie's "man is bad" message was more than I could watch.
