Believe it or not, but we may have our first gardens on the surface of the moon as soon as 2012. As part of Google's Lunar X Prize, Paragon Space Development Corporation and Odyssey Moon have developed pressurized greenhouses designed to grow a plant from a seed on the surface of the moon.
Obviously, figuring out how to grow plant life on the moon is the first step towards sending people to live on it and other planets. Once they figure this step out, they'll be able to produce food and oxygen, two things sorely lacking on the moon's surface. Then I'll finally be able to live there, at long last.
