An Avalon spouter's attempt at explaining climate change on other planets as compared to earth is very insightful. He pointed out that each planet is unique in itself as well as the earth. Where his argument falls apart is in the similarities of said planets. They all revolve around the same star, they are all experiencing climate changes. That is where their similarities end. The idea that because the earth has humans on it doesn't make a difference, since every planet is unique in itself. They all have the same thing, climate change, yet earth is the only one with humans.
