Space exploration. Someday it will be possible. When this happens and we start going off to other planets or living in space ships… What does that mean for our planet earth? Our bodies are made up of 70% water, and I would have to say a significant part of this planets ecosystem.

So if we start leaving and taking the water we retain and other food, supplies, plants etc. what would happen to Earth? Would nothing change, or would the balance of nature be thrown off?
