Agree, except earth after full on nuclear war is still likely better than best possible Mars.

Especially considering timeframes needed to improve Mars, vs timeframe to get past initial post nuclear war issues, which are likely not as bad as the worst case scenarios we've been taught about.

Also, I always found it interesting that the people that are so scared of us changing/destroying the world with nuclear war, are the same ones that don't think twice about basically doing the same thing (drastic manmade change) to another planet.

Or that they think it would somehow be easier than a similar feat of geo engineering to repair earth, either post climate change or nuclear war.
