Re: Protein production  

If we can make robots then maybe we can make an artificial cow that makes milk from green waste.

hmm... my mental is having a problem with that image in my head! but i'd be willing to try tasting it

Who needs meat when we can grow Mushrooms and Spirulina ? :-)

The idea of raising animals in zero G for protein is, as some pointed out, a rather daunting task. If we were to go that route it'd likely have to be smaller animals that take up less space/use less resources. Crickets as some have mentioned or other insects would be a good choice there, beyond that my next suggestion would be a bird such as a chicken to provide an egg supply.

As for using plants and/or mushrooms. They provide problems of many of the plant based solutions for protein provoking common allergic responses to some people. So we'd need to make sure there was a decent selection to choose from eventually. That said, they are some of the better options since they could also help keep the CO2 levels down. I don't know enough about mushrooms to be able to advocate for or against them, but I do feel that they are more likely to be able to handle some of the issues of space than plants can.

Next on the suggestion of GMOs, I personally think those would be perfect, if not necessary, for space and for future colonies beyond Earth. Most GMOs given to the public are tested thoroughly to be as safe as possible, at least as much as any other food we consume if not moreso. Furthermore, they may be able to be modified to not only survive better in microgravity, but also to provide a boost to nutrition. I certainly wouldn't dismiss the need to continue studying them at the very least. The more we study and practice genetic modification, the better we'll be at it and the safer it will become as well.

Finally, it's quite the feat to make a fully self sustaining space station, but alas, on their own they'd never be able to have enough continuous resources to keep up the agricultural needs. Space stations will likely always need resupplies from planetside. They may be able to stay sustained for a while, but even when recycling waste there's a slow decline in what can be produced without fresh resources. I foresee symbiotic relationships between space stations and their planets. The planets provide the agricultural requirements while the stations provide satellite services, satellite maintenance, heavy industry work, and possibly even energy collection that can be sent down to the planet.

My response to your points number 4 and 5.

I agree on point number four, also the smell would be horrible in a rather closed system. Honestly, I feel like chickens would be less suited to space stations and more suited to livestock for colonizing other planets.

For point five, I think you and I are thinking about different allergies. It sounds like you might be referring to like plant pollen allergies which, while annoying at times, generally aren't dangerous. I'm referring to food allergies. Being allergic to nuts, soy, and the like, many of which are common non-animal sources of protein. Those are common allergies and can be fatal to those allergic.

Probably a stupid thing to bring up here, but... 

We are not in space yet, so how about we concentrate on the things we can test here already and put it to good use? 

We could create mini-home labs (we don't have enough funds to get into space so we don't want to waste it on an expensive earth based lab?). There are a lot of crazily intelligent people here with awesome degrees in science that could/should coordinate the mini-home-labs. 

They know best what is needed to test, but I can imagine there are elements such as: how to grow plants with less water, use artificial light only, fully immersed plants (aquaponics requires gravity, at least the forms that I have seen so far), balance of micro-eco-systems (raise bugs to eat, how much material you need to feed, what can you do with the waste, can you make an eco-system out of that where you can take out which number of the population and still sustain that micro eco-system?) etc... 

If any breakthrough can be made to have a sustainable, light-weight, cheap source of protein, you don't have to drop food out of space where it is needed,... we give them the fishing-rod instead of the fish?
