The free enterprise system that we have in place now is an excuse to continue raping the environment. The whole concept of how we utilize all resources on this planet has to be reviewed and adjusted so we're working harmony with nature instead of working against it.We should first try to solve the many problems here on Earth, before we look to colonize or venture out to other planets, that may not even be able to support human existence. Fix the problems in our home Earth, before we look to venture away from the Earth.
