We are to multiply and flourish on earth and in the vicinity of stars. Our inventions will solve each problem that we perceive. Throughout space, the radiant energy and ion storms that have been so hazardous to our astronauts will be used to our benefit in our machines and dwellings. Our future is not tied to the surface of planets. Nobody should be scheming to reduce the population of the earth, or to reduce our population growth anywhere.
Our advantages and opportunities are abundant. Currently understood technology is capable of capturing huge amounts of energy and materials in space. Overpopulation of the solar system will not happen anytime soon.
