 We're going to be here 20, 30, 40, 100 years from now. The question is, what are we going to plan to do so that no matter where we are on the planet, we will be in charge, we will have a high quality of life, and that we can save the planet, or excuse me, we can save the habitability of the planet for human beings and life on at least the surface of the Earth. And that's what we need to be concerned with.
