During this time of Covid19, I am reminded yet again of what we should have been doing before this. I believe that the nations of the world should have made an alliance when we first started sending people into space. This alliance should have been about spreading mankind to other planets, so that no disease or calamity could wipe out the human race. Part of this alliance would be to find out ways to get resources from space. Perhaps they would do this by mining asteroids or finding a suitable planet to terraform into a planet where the human species could live. Even if we can't figure out how to terraform a planet we could still mine asteroids and build a fleet of spaceships to defend Earth from threat, be it aliens or some other threat from space.
