Express a pessimistic viewpoint regarding the future of humanity and how other living creatures might perceive our actions.
It will be perfectly appropriate when the human race, through neglect and stupidity, brings about its own extinction. The devout will mutter, "It's God's will," the atheists will insist, "There's no God to fault," and other living creatures (apes, beavers, your dog or cat) will frown at us and spit, "You idiots!"
