Can we create a self-sustainable civilization on the moon or another planet?

So it seems like NASA is gonna be sending a colony to the moon soon. I am wondering how that will work? Where will they get food, water and oxygen? But my main question is: are there any ways to perhaps grow (or even synthesize) those things? (food/water/oxygen) Without any help from our planet what so ever. I know that for electricity and heat we could use solar energy, but not sure of the rest.
