God damn it this board is hilarious sometimes.
>>8139795>So I can move to mars without having to subscribe to vegerianism?Well tough titties Charlene, you're going to have to give up meat for the foreseeable future if you want to live on Mars.
>Well, where do you expect to get food from then?I don't know what that other anon was getting at but I'll tell you where you'll grow vegetables: in water. Hydroponically grown food is magnitudes more effective than traditional farming methods, and it's the only way you will ever be able to safely eat anything grown on Mars. Plants absorb heavy metals and this is obviously a bad deal if you have vegetables, and furthermore using Martian regolith would -suck- for growth medium. Ignoring the perchlorate problem and the associated water it would require to fix, the process in which organic nitrates are formed in Earth soil needs certain bacteria. Most of the available nitrates in manure (especially from humans) just simply isn't compatible for most plant life, it needs to be broken down into first ammonia and then into a compatible nitrate. All of this requires an exponentially increasing amount of preparation and work for every cubic inch of soil. Oh and then there's the process of irrigating this mess of complicated shit that is just... dumb. Instead taking that same water and putting it through a hydroponics system you solve two problems: water for the plants and grow medium.
Nutrients can be done in a variety of ways, but the best way would be recycling organic matter in a composting bin (this is necessary either way) and then diluting it in water and applying to the plants. ("compost tea") Beyond that if you truly, truly want some meat in your diet an aquaponics system uses a lot of water but it does offer the benefits of aquaculture to the equation. How fish would fare spawning at 37% of Earth's gravity I don't know, but I imagine it's not going to be that big of a deal.
