I was thinking I know we won't get to space in my lifetime as a whole county but for the future of our children, who will likely achieve our goals of independence from Earth, their bodies wouldn't take the stress of eating Earth food, e.i. Hamburgers and stuff to processed food from Agricultural farms up there, if we could start to develop plans to make that food available now we could alter our diet to a more course mix of fruits grains, nuts and a lil meat so our bodies can adapt to that and our DNA for that will carry over. Make it easier for them to thrive. But this is all food for thought* I'm not a scientist or anything like that. Just a concerned Asgardian.

This needs major thought, of the fact this is what needs deep though

It generally requires millennia to make genetic changes with regards to diet. For the time being, I expect our diets will remain similar to what they are now.

Yeah probably but will we have hydro farms?

Probably.

KGM

then we are good, because hydro farms are all we really need, sadly nothing that comes from animals that help us, but at least animals won't be harmed to supply us, in fact there's a company trying to extract proteins and DNA of animals so we can grow the same meats we eat just without actually killing, do you think that will be an actual thing when asgardia is done? I hope so

You are not bearing in mind preferences. I am a meat eater. I will want meat. If you want to be vegetarian, fine, but I likes my cooked muscle tissue.

Phickur I am a meat eater also, but we are suppose to be more evolved and try to be better than those who cant comprehend that we are failing because of certain acts. Do you know how those animals are treated? It's disgusting and inhuman, I'm suggesting we should talk to the company who takes the DNA and cells needed, without harming animals to grow this meat we love. Don't assume something from a suggestion. I love my burgers and steak.

Having previously lived on a farm, I am well aware of how animals are treated. Just because some documentary filmmaker decided to find some shitty places and recorded the animals' treatment there and then goes to say all animals are treated that way is manipulation, not journalism or entertainment.

Domesticated animals are kept for two reasons: company, and food. Animals, in the vast majority, are only interested in the propagation of their species. Anything that doesn't get them closer to the goal of making little animals really doesn't factor much into their thinking. Domesticated animals do not need to worry about predators, where to get their next meal, or how to find mates. Humans do all of that for them, so their propagation is assured if they just sit around and be comfortable all the time. Sure, they will die when the humans get hungry, but it is a lot longer than they'd live if they were out in the wild, where they'd be food for some other animal who would kill them with a lot more stress and violence than what we humans use.

So, no, I don't think people who eat meat are 'less evolved' than others. If anything, I believe the vegetarians are intentionally regressing their evolution back to the stage where humanity didn't eat meat, many thousands of years ago. That whole 'omnivores are less evolved than herbivores' line is vegetarians justifying their life choice and attempting to guilt others into believing they are right. Fine by me if they want to live that way. When we met, my wife was a vegetarian, and I supported her in not eating meat (more for me!) but, after over a decade of marriage, she now eats a bit of meat every now and then. While she was pregnant with our daughter, my daughter insisted on her eating a lot of meat, which sort of ended her purely vegetarian streak.

_{who said meat eaters are less evolved? No animal treatment pretty much everywhere is bad, some countries they are used to see the effectiveness of weapons and tools, I want to live in a future that is animal cruelty free, like I said people want to extract DNAand cells. Which we can choose the growth. We can grow steak, pork chops, chicken, and etc. Without harming animals. I don't mind vegans, unless they are snobby baggers acting like their perfect. Meat is very healthy for you and is needed. Documented films show animal cruelty all over, you may be thinks it's not inhuman to treat animals bad because it gonna n turned into good. I do think it is, imagine every animal that's harmed and killed inhumanly and switch the animal with a human, how would you feel then? Outraged? Probably. Think of animals as people, they may not be civil but I like hunting, and understand, but even so they are treated inhuman before killed. So why should other animals be inhumanly treated?}

Cruelty is a symptom of a disease, which most of us call evil. We are all carriers, and those who are infected with it can spread it through their actions. In order to eliminate cruelty, we need to be able to quantify-ably identify and eliminate the disease of evil.

Then animal crueltyshould be 1 of the top 5 to to stop of these desieses. Being inhuman is less evolved. We need to be the higher evolved.

Genetically modified algae would be a good idea it grows quickly an can be used as a co2 scrubber

I was thinking we could just grow crops in specialised environments. A NASA found that growing wheat in a high-light, high-CO2 environment yielded three to four times more wheat than in regular atmosphere:

As for meat, by the time we've built our first space station, lab-grown meat will be a thing, so there'll be no need to slaughter animals for protein (we might keep some around for dairy/eggs/DNA harvesting). We could potentially do the same thing with fish, if the technology has advanced enough:

Hello !

We must think about the essential elements:
     lipids
     proteins
     carbohydrates

Algae must be the best idea, and in parallel, consume CO2 products oxygen

A studies exist in pumed about that :

And Nasa think about a system in microgravity too :
