Scientists have warned that when humans ‘inevitably’ set up space colonies they could turn to cannibalism if crops and farming systems fail.
They said future colonists will end up eating each other if they run out of food and don’t receive regular supplies from Earth.
Experts warned that more preparation was necessary given that humans could start colonising parts of space by the end of the 21st century.
The specialists, speaking with Metro, flagged disease, food sustainability and self-sustenance among the major issues that would need to be tackled before successful colonisation.

They suggested Calliston, Jupiter’s moon or Saturn’s second largest moon Titan as possible locations for humans’ first permanent settlement in space.
Charles Cockell, a professor of astrobiology at Edinburgh University, said: ‘Even with the best technology, isolated human communities can degenerate very quickly.
‘If you put a group of people on Callisto, things start going wrong and the plant growth module breaks down, they are going to eat each other if there is no other way to survive.’
Experts said preparation is necessary given that humans could attempt to venture into living in space by the end of the century, if not as soon as in the next 30 to 40 years

For this reason Mr Cockell believes any ‘systems’ in place need to be tested before humans brave settling in the final frontier.
Dr Cameron Smith, a Portland State University anthropologist, added proper farming and food sustainability methods must be put in place.
But he was more optimistic that humans wouldn’t resort to eating each other if faced with shortages, adding that historically there are different examples of how humans have responded to surviving testing environments.
Dr Smith also said disease would be an important challenge to overcome, suggesting that populations would be able to quarantine if segmented into independent settlements.

Both academics believe humans should test out colonies closer to home – Mars or maybe even our Moon – where supplies from Earth would be more feasibly obtainable should anything go awry.
Professor Cockell believes the technology with which we could live in space already exists but must be throughly tested, and that colonies on Mars are possible in 30 or 40 years, with Callisto on the horizon only 100 years after that.
However Dr Smith thinks attempts would only be plausible by the end of the century.
