"pro-human and pro-Earth "

No such thing- to be pro-Earth, one must consider the human population loading that would NOT change the environment. Estimates vary, from 500,000 up. IF the goal is a static environment ( which is NOT natural) than we need to get rid of at least 99 out of every 100 people.

I am sure we can depend on our resident Ubermench to decide who has to go.
