Alte landwirtschaftliche Praktiken könnten dazu beitragen, Menschen auf dem Mars zu ernähren

>In order for future humans to [survive on Mars for long stretches at a time](https://www.popsci.com/how-will-we-eat-on-mars/), nutritious food is going to be essential. While learning how fake astronaut Mark Watney grew potatoes in the [sci-fi novel and film *The Martian* was entertaining and informative](https://www.popsci.com/realism-makes-martian-one-greatest-sci-fi-films-all-time/), real astronauts should have some helpful resources from planet Earth for growing food in future Mars settlements.

>To learn how to best do this, scientists on Earth must simulate the unique conditions on the Red Planet here. Mars’ atmosphere is about [100 times thinner than Earth’s ](https://www.space.com/16903-mars-atmosphere-climate-weather.html)and is mostly made up of carbon dioxide, nitrogen, and argon gasses. Entire Martian colonies in the future will need to be set up in controlled enclosures similar to greenhouses with an Earth-like atmosphere of the right mixture of oxygen, nitrogen, and carbon dioxide.
