The USA Space scientists at NASA are planning for the distant future when they might consider human colonies on the moon or Mars and how they could be fed. Sending cows into space would be costly and in any case using cattle and chickens would be an inefficient way of using the limited space, but the controlled life-support system of the space station could easily cultivate grains, vegetables and fruits.

Some of the plants suggested were rice, wheat, quinoa, oats, potatoes, soya beans, other beans, kale, broccoli, carrots, peanuts, lettuce, onion, tomatoes, etc - in fact, all good vegan food and it sounds like an interesting varied diet that would also grow well on our hungry planet.

Four vegetarians helped with this project, including Patricia Carney of EarthSave Foundation, who asked the panel to extend the same principle to Planet Earth as they would to their own space station.

So in a few more millennia may we find that a vegan colony has been established on the star "Vega"?
