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.
所以，当我们考虑我给你们展示的这个系统时， 我们可能要想个更远些，也就是说， 我们需要从水，特别是淡水入手， 因为淡水将是未来一个亟待解决的问题， 我们现在就在研究开发 重新利用废水的方法。
