Yes, a mission to Mars would be cool, but how about something TRULY EXTRAORDINARY! Let's scrap the Martian musings and spend the equivalent time/money/energy on saving the biosphere and making life better for all lifeforms that occasion this miraculous jewel of a planet?
We have to leave Earth because humans can't possibly fix the climate. We'll move to Mars.
Wait. There's no atmosphere on Mars.
We can make one. It'll be fine.
