> How can the same people be worried about human extinction as a result of environmental collapse, also think we might be able to develop a sustainable colony on Mars.
We would control the size and direction of growth on a colony. As it stands the tradoffs we make with regard to earth's climate affect 7.5+Bn people. A colony can be planned/optimized before we get there. We don't need to terraform the entirety of mars to get a small colony. If you want to have mars rival earth, then we can start talking about the scales of comparison you're making.
