Well, the fact that it is Earth doesn't stop the air from being poisoned by horrid pollution. There are already places on modern day Earth where if you are not wearing a gas mask you can get killed by the air quality (Looking at you China). Several thousand years of evolution could also have shifted the predominant air chemicals to a much more toxic, unsurvivable supply. Notice how you see no animals in these tilesets, despite it being a forest. There are more animals on a moon around Mars than in Earth's own forests. Suggest that something is pretty toxic there.
