Humans could end up eating each other if crops fail when we finally set up colonies in space.
Scientists have explained why humans living on other worlds is ‘inevitable’ but potentially dangerous
But first, they suggested we should try out tester colonies on Mars or our own Moon – where it would be still possible to send supplies from Earth relatively easily if unexpected problems arise. He told Metro.co.uk: ‘The systems have to be really reliable and that’s why they need to be tested before. ‘One of the first things that they would have to do is establish a really good farming system and put in a lot of stored food’, he explained.
He suggested that the economies on such locations would have to be trade-based to start with, and would be unlikely to have anything like the sort of economic activity western populations are used to under capitalism.The academic branded 3D printing a ‘game changer’ but still thinks a farming-style, ‘almost medieval’ community is most likely.
He cited the example of a Uruguyuan football team who worked together constructively after being stranded without food after a plane crash. The survivors did turn to cannibalism, but only among those who had already died.
