> We can't even fix the problems on our first planet. How (and why) can we even begin to think about another one? By this logic we never go. There will always be giant seemingly insurmountable problems. If we solve climate change there will just be another, and another, and another. Life is a never ending fight against entropy. There will never be a time when we have it all figured out. Secondly it’s entirely possible that the stuff we learn trying to survive off world will be applicable to making life here more sustainable. It could force us to figure out how to run industry efficiently with a very high percentage of material recycled, and how to run an economy without a lot of low entropy ecosystem to draw from. Also no fossil fuel. They don’t exist. We’d only have nuclear and solar really.
