As if things weren’t going to be tough enough for future space colonists, experts now say that they’re likely going to face food troubles — and that might just turn them into cannibals.
Charles Cockell, professor of astrobiology at Edinburgh University, spoke to Metro about the challenges astronauts will face if and when humans attempt to colonize places such as Jupiter’s moon Callisto and Saturn’s moon Titan.
Specifically, Cockell stressed that if the farming and crop systems failed, the colonizers would likely face very dire consequences unless they received regular supplies from Earth. If they’re far away enough — or if Earth collapses completely — this might not be possible.
To underscore his point, he pointed to Sir John Franklin’s 1845 exploration of the Arctic that resulted in the crew cannibalising each other.
"Franklin’s crew tried to find the north-west passage on ships in the late 19th century — they were the most sophisticated pieces of technology available at that time," Cockell said. "They had tinned food, which was the new technology — and yet, they got lost, stranded and they ended up degenerating into cannibalism."
"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," he later added.
While this might seem like a fairly bleak prediction, Cockell’s message actually serves more as a warning. The crop systems would need to be tested and refined on places like the Moon and Mars before colonizers are yeeted off into the far reaches of space.
Only after adequate testing can we be certain that colonizers won’t have to do their best Donner Party impression to survive.
"If you are going to dump 20 people several hundred million kilometers away from the Earth in an instantaneously lethal environment on a moon, you better be sure that is going to work because if it doesn’t it is going to fall apart quite quickly," he said.
