I was talking to my kids last night about the importance of space travel. It seems inconsequential and a waste of money, but people don't realize that space travel is essential if we want to ensure our survival and the survival of other life on Earth. Right now our eggs are in one basket and one massive catastrophe and we're all screwed.
Once we get into space and can begin to tap lifeless planets for resources where--get this--there aren't even any food chains--our expansion and growth as a species can really begin. The more I think about it the more my mind is blown at the possibilities.
