We have been incredibly successful in eradicating our competition big and little.Ah, so size matters in the success argument? It's only bigger things that eat us that we're competing with, not even smaller things that eat us?
That asteroid that wiped out the dinosaurs did us a massive favour. We wouldn't have reached this level of technology if the huge carnivores hadn't died out. It's really only the past few hundred years where we've had technology that would have given us a chance against them if we'd tried to encroach on their territory. Does that make us a success? I'm not so sure. We've "won" by a technicality alone, essentially. T-Rex and its supercarnivore contemporaries around the world were probably the most successful large vertibrates in history IMO.
Oh, certainly more efficient. Alternatively we could just nuke a few large population centres to get the numbers down. Faster again, and much less organisation required.
We could blame it on the muslims and give us an excuse to annex the Middle East in the process. Win-win!
We have done it wherever we went.
As for the nuclear option it makes more sense than your, only sensible people can breed scenario.
As for climate change what do you recommend other than mass sterilisation?
