Jeff Bezos dismisses idea of a backup plan, says we must protect Earth
During the last year Amazon founder Jeff Bezos has begun to open up about the scale of his ambitions with the rocket company, Blue Origin, explaining that he envisions millions of people living and working in space. Additionally, Bezos has talked about moving heavy industry off of planet Earth to create a garden paradise on our home planet.

In this view Bezos' philosophy differs significantly from the other titan of the new space industry, Elon Musk of SpaceX. Both men agree that reusable spaceflight is essential to lowering the cost of access to space, but they disagree about what to do once we get there. Musk has spoken openly of providing humanity with a "backup plan," and recently revealed his ultra-ambitious plans to colonize Mars with 100 passengers at a time via his Interplanetary Transport System.

Bezos dismissed this approach on Oct. 22, during the Pathfinder Awards at the Seattle Museum of Flight. In remarks first shared by GeekWire, Bezos said Earth should be zoned as a residential area. "I don't like the Plan B idea that we want to go into space so we have a backup planet," he said, noting NASA's efforts to send probes throughout the solar system. "Believe me, this is the best planet. There is no doubt this is the one you want to protect. This is the jewel. We evolved here, we're kind of made for this planet. It's gorgeous, and we can use space to protect it."...
