For Bezos, colonising space is a more a simple necessity for continued life on Earth. The compound effect of the incremental increase in energy requirements will mean us having to cover every inch of Earth in solar cells, he said, while the solar system offers virtually unlimited energy resources.
"We can harvest resources from asteroids, from Near-Earth Objects, and harvest solar energy from a much broader surface area – and continue to do amazing things," he said. The alternative, he said, was an era of stasis and stagnation on Earth, where we are forced to control population and limit energy usage per capita.
"I don't think stasis is compatible with freedom or liberty, and I sure as hell think it's going to be a very boring world – I want my grandchildren's grandchildren to be in a world of pioneering, exploration and expansion throughout the solar system."
He also suggested that exploration and colonisation of the solar system would make it possible to support one trillion people.
"Then we would have 1,000 Einstein's and 1,000 Mozarts, how cool would that be?" he said.
"What's holding us back from making that next step is that space travel is just too darned expensive because we throw the rockets away. We need to build reusable rockets and that's what Blue Origin is dedicated to."
