This whole "supreme species", "top of the food chain" argument really grates on me.

It's one thing for a species to prey on other animals, deplete their numbers to where they're too tough to find, then adapt by hunting other prey, or by dieing off to numbers that the existing prey will support.

It's another thing entirely to destroy your prey species, or even non-prey species (this is the real difference between us and other animals) with secondary means like dumping sewage, pesticides, and clear-cut debris into their habitat.

Other species leave non-prey species pretty much alone, and intact. We don't. Just because we have the capability to affect pretty much every species around us doesn't mean it's right to do so.

No, I'm not suggesting that spending $Ms to protect a fly, or bankrupting 1400 farming families to protect a sucker is smart management, but decimating species out of indifference is NOT an indication of supremacy in my book.

Face it, as a species coexisting with other species, humans are arrogant buttheads.
