The “Fix earth first” crowd seems to think that human nature will allow them to fix earth before we ever do anything again.
War is a beautiful example. Humans have been fighting wars for thousands of years. Persians gathered up armies and walked thousands of miles to fight with people they had never encountered before. Its pretty likely that Neanderthals slaughtered others of their kind when they came into conflict.
I use to think the Fix earth first wimps use to be only libs, not any more.
