Just to be picky, it's not the thinness of the air, it's the shortness of the growing season. Get up high enough, even in the tropics, and you're out on the tundra. The farther North (or South) you go, the lower the elevation this occurs at. Up in Northern Canada there's a "tree line" that streches all the way across the continent!
