Since my species was created by nature, isn't everything it does natural?
The earth made the mistake of allowing such an ignorant, shortsighted, destructive species to reach the top of the food chain. I think anything that our species does to the earth and ourselves lies within the realm of nature, and is consequently, nature's fault.

Humans are going to cause global extinction because humans are morons. And, really, that is all we ever could be.
