Jeff Bezos thinks we need to build industrial zones in space in order to save Earth

Elon Musk wants us to build human colonies on Mars. Jeff Bezos has a slightly more measured take.

Onstage at the Code Conference on Tuesday, the Amazon founder and CEO said that we have to start bringing parts of the industrial economy to space in order "to save Earth."

"Let me assure you, this is the best planet. We need to protect it, and the way we will is by going out into space," he told Recode Editor at large Walt Mossberg. "You don't want to live in a retrograde world where we have to freeze population growth."

Bezos says tasks that require lots of energy shouldn't be handled on Earth. Instead, we should perform them in space, and that will happen within the next few hundred years.

"Energy is limited here. In at least a few hundred years ... all of our heavy industry will be moved off-planet," Bezos added. "Earth will be zoned residential and light industrial. You shouldn't be doing heavy energy on earth. We can build gigantic chip factories in space."

Solar energy, for instance, is more practical for factories in space, he said.

"We don't have to actually build them here," he said. "The Earth shades itself, [whereas] in space you can get solar power 24/7. ... The problem with other planets ... people will visit Mars, and we will settle Mars, and people should because it's cool, but for heavy industry, I would actually put it in space."

No word yet, however, on when Bezos plans to move Amazon fulfillment warehouses beyond the surly bonds of Earth.

Will you support Vox’s explanatory journalism?

Most news outlets make their money through advertising or subscriptions. But when it comes to what we’re trying to do at Vox, there are a couple reasons that we can't rely only on ads and subscriptions to keep the lights on.

First, advertising dollars go up and down with the economy. We often only know a few months out what our advertising revenue will be, which makes it hard to plan ahead.

Second, we’re not in the subscriptions business. Vox is here to help everyone understand the complex issues shaping the world — not just the people who can afford to pay for a subscription. We believe that’s an important part of building a more equal society. We can’t do that if we have a paywall.

That’s why we also turn to you, our readers, to help us keep Vox free. If you also believe that everyone deserves access to trusted high-quality information, will you make a gift to Vox today?
