The belief that human beings are somehow better, or more important, than everything else in the world is a toxic and illogical way of thinking. To pursue whatever we want to have at whatever the cost isn't just stupid, it's ecologically unsound. When we go out and cut down trees to put down bigger parking lots, or overfish the seas of the world without taking into consideration the damage that might cause to the environment or the local ecology is, in its own right, self-destructive behavior. By putting our immediate needs before the needs of everyone and everything surrounding our decisions, we're cutting off our own legs. Eventually all the consequences of our actions will catch up to us and we'll not only be risking the extinction of species of animals, but also the extinction of humans. You can't fuck with one part of the food chain and not effect everyone else, after all it is a CHAIN. We are all linked together. If it's bad for one person, it's bad for everybody.
