No planet B

Maher's new rule on the sci-fi nerd fantasy of colonizing Mars. He rightly thinks the money for that expedition would be better spent investing in our home world. And by the way, if we took care of our home world we wouldn't need to move to Mars. It's the very notion that we can just destroy our environment and then move somewhere else that in fact contributes to that very destruction. Maher isn't anti-science, since we need that science to address the climate crisis. He is though anti the sort of science that thinks we can just destroy our planet because we have the capacity to move on.
