也许对于我们来说，水、电、食物这些资源是取之不尽的，但是，你可否想过：在地球的另一方，有人因缺水而死亡，因饥饿而失去生命。

Perhaps for us, water, electricity, food, these resources are inexhaustible, but, you may want to: on the other side of the earth, people died for lack of water, lost their lives because of hunger.

问题是我们没有取之不尽的资源。

The problem is we don't have a bottomless pit of resources.

《柯林斯英汉双解大词典》

当然不是，水不是一个取之不尽用之不竭的资源，同时他对我们的生活而言是很重要的。

Of course not, water is not a never-ending resource, and it is the most important thing for our life.
