Earth, unfortunately, seems to become day by day a more dangerous place, considering climate change, the conflicts among some states, the poverty in others or the corruption from most of the world. Therefore, finding another home for us humans, another planet to colonize seems to be a wise decision.
Some scientists and Elon Musk have been trying to figure out ways to get to Mars since a couple of years, but one big question is how will we feed ourselves if we get to the red planet. And let’s not forget that the scenario from “The Martian” with seeds being planted in the Martian soil is first of all Science Fiction.
It would take 100 years for a food system to be self-sufficient
According to a study done by scientists from the University of Central Florida and published in New Space, it would take 100 years for a food system to be self-sufficient for the first one million Martian residents. But still, in order to survive, people would need to bring a tremendous amount of food from Earth.
For people to permanently be living on Mars, it would be mandatory the producing of food on the red planet, but the Martian soil and actual atmospheric conditions couldn’t allow it. Therefore, according to the study, humans may need to build 14,500 kilometers of tunnel segments to host there enough food to feed one million people.
How about raising farm animals on Mars?
Raising chickens, ducks or cows to provide eggs, meat and milk for future residents of Mars, shouldn’t theoretically be a bad idea, but transporting the animals through space is the main problem. But instead, we may produce protein-based food in the lab, due to insect farming and cellular agriculture. This alternative is also proposed by the study published in New Space
We can’t rely on exoplanets in order to build a civilization there since they’re way too far away from us, so the only option remains Mars. Venus and Mercury are too hot and the other planets from our Solar System don’t have solid surface, except for Pluto which is too far from us and too cold. Other options may be moons of Saturn or Jupiter since they are very numerous, but we don’t actually know enough about them.
