So we may be able to go beyond that when thinking about this system that I'm showing you, and that is to say we need to think in terms of the water, the fresh water, which is also going to be an issue in the future, and we're working on methods now for recovering the waste water.
Misschien kunnen we zelfs verder gaan dan met dit systeem en methodes bedenken om het zoetwater - dat schaarser gaat worden - in de toekomst te gaan herwinnen.
