There is nothing on Mars to support the murderously naive idea of a "colony." Everything would have to come from Earth at great, increasing, and continuing expense. In return for what exactly? Billions to support ONE person on Mars. How much to support a million? But that just presupposes that it can work for argument purposes, which it cannot. We are the Earth, not Mars. They would die on the way to Mars or shortly after getting there. There is no separation possible. But, most importantly, the most fundamental of human rights is the right to be born, live, and die on the Earth. You may be able, as an adult, to give up your right to live and die on the Earth, but you can never willingly give up your right to be born here and so be able to consciously make the other two decisions. We need the United Nations to declare the fundamental human right to be born, live, and die on the Earth. Your parents do not have the right to strip from you the most fundamental of human rights.
