For my money, we haven’t destroyed the Earth nearly enough.
Are you talking about the “warfare” in Iraq started by a chimp?? 
I’d like to see an example - any example - of an organism on earth that acts purely for the benefit of some other species, without regard to its own well-being. Even if you accept that humanity’s actions are purely selfish, it doesn’t follow that we’re the most selfish, unless you can demonstrate some level of selflessness in other species.

It’s good to know that the human race can depend on you.
Could you do a little drinking for me? My meds don’t allow me to drink. I can handle my end of the posting, though.
