The billionaire thinks we will live in giant spaceship colonies near Earth rather than on other planets.
He reckons it would see Earth itself protected and left purely for homes and light industries, while the human population could explode.
Bezos, worth an estimated £101billion, said: “The solar system can support a trillion humans. We’d have 1,000 Mozarts and 1,000 Einsteins. Think how incredible and dynamic that civilisation will be.”
He and his team, Blue Origin, are working on a transport option to get into space.
They plan to land a robotic cargo carrier on the Moon by 2023.
Bezos liquidates £750million Amazon shares a year to fund his private rocket company.
The businessman says moving large numbers of humans to other planets would cost too much and defended his plan for spaceship communities.
He told the Yale Club in New York: “I don’t think we’ll live on planets. I think we’ll live in giant space colonies.”The primary benefit is that they’ll be close to Earth.
“People will be able to come and go. Very few people are going to want to leave this planet permanently – it’s too amazing.”
Taking a swipe at rival Elon Musk’s Space X project, he said: “My friends who want to move to Mars, I say: ‘Do me a favour, go live on top of Everest for a year first, and see if you like it. Because it’s a garden paradise compared to Mars.'”
