Asteroid mining would be cool too. It would certainly slow down the destruction of our planet.
Slow it down, maybe. But the amount of earth's resources required to launch and operate spacecraft takes a terrible toll on our environment!
Science that takes toll on our environment can be justified for the greather good, and can help restore environment to healthier levels.
Anyways, i dont believe that asteroid mining would slow down anything back here on earth, they would just multiply the greed by two..
