人们总以为淡水是取之不尽的，实际上淡水资源是很有限的。请谈谈你的看法。
It is generally believed that there is a good supply of fresh water. But to our disappointment, the fact is just the opposite.
As we can see, the world population is growing rapidly day by day. So enough fresh water is needed to feed such a big population. Whats more, with the development of industry, factories and vehicles produce poisonous gases or wastes, which consequently results in the pollution of water. Though fresh, a good amount of it can no longer be used. Only quite limited fresh water resource is available to human beings. So its high time for us human beings to take quick action to protect water resource. Stop pollution and save water, otherwise, we cannot survive on the earth.
With fresh water, the world will be prosperous.
人们普遍认为，有一个很好的食水供应。但令我们失望的是，事实恰恰相反。
我们可以看到，世界人口正在一天天地迅速增长。因此需要足够的淡水养活这么多的人口。更重要的是，随着工业的发展，工厂和车辆产生有毒气体或废物，因而造成了水污染。虽然新鲜，但好大一部分的水不能再使用。只有很有限的新鲜水资源可供人类。所以这是我们人类采取快速行动，保护水资源的时候了。停止污染和保存水，否则，我们不能在地球上生存了。
只有新鲜的水，这个世界才会繁荣。
