In my science book, there is a picture showing that earth would be frozen over if there were no greenhouse gasses, but everyone is saying that theres too much and global warming is occurring... I'm guessing that theres a point to which they are good... you need just the right amount of gasses to keep life on it, correct?

A couple days ago I was watching Planet Earth with my science class, and in one of the episodes (I don't know which) it showed an ant moving as if it were drunk, and then dying... then it showed a plant sprowting from the ant's body. I wrote down the title of it, but I think I spelled it wrong. The word is "Quarticepts Fungus" but its probably spelled wrong. Has anyone heard of this, and where can I find more information about it?

Thanks!
