What could possibly make Earth as uninhabitable as Mars, without destroying Mars as well?
Almost nothing. I agree the Mars colonialization idea is absurd in any foreseeable timeframe. My point is mostly fantasy seems serve to numb people to the damage to Earth that's now going. If someone is worried about the future of the human, they should be working on climate change. Especially if they have enough money and influence to make themselves widely heard, as do many of the people hocking the Mars-boondoggle.
