Intelligence gives us godlike powers over all other creatures on Earth—which has not been a fun time for the creatures. If any of their body parts are possible value creators, we have major industries processing and selling those body parts. We sometimes kill them for sport. But we’re probably the least fun all the times we’re just doing our thing, for our own reasons, with no hate in our hearts or desire to hurt anyone, and there are creatures, or ecosystems, that just happen to be in our way or in the line of fire of the side effects of what we’re doing. People like to get all mad at humanity about this, but really, we’re just doing what species do—being selfish, first and foremost.
