Sorry Humans, but the idea of populating other planets is a fantasy of ridiculous proportions. We have one beautiful and amazing planet. It is the only one we can or will ever live on. But we have no discipline or will power, and we are destroying the planet and the many species of life that we share it with. We need to use all of our brains to learn how to manage our population and live in sustainable ways on Earth. There are no shortcuts or escape routes.
