The urge to grow and develop, present in all forms of life, becomes perverted in the Bisy Backson's mind into a constant struggle to change everything (the Bulldozer Backson) and everyone (the Bigoted Backson) else but himself, and interfere with things he has no business interfering with, including practically every form of life on earth.
Eeyore religion says that the earth isn't worth saving, anyway, and that when it comes to an end, the Faithful will be transported instantly to heaven. No problem. We'd like to see them explain things to Saint Peter at the Gate, when he asks them what they did with the world that God entrusted to them. That might get a bit sticky.
