1. 随着工业化（industrialization）的推进，地球上的淡水（fresh water）越来越少。
2. 生命没水就要消亡（disappear），因此人类要珍惜（treasure）淡水。
3. 我们如何节约用水。

Water is important in our life. As humans, we are water and oxygen based organisms, as are many organisms on earth.

Without water, we will dehydrate and die. From Joozone.com.

The earth's crust makes up less than 1% of the earth and all the oceans on the planet are in the earth's crust.

Therefore, water makes up less than 1% of the earth. "One drop of water is one drop of life." The human body is something like 70% water. We heavily reply on water to survive.

We need to take care of water. As the progress of our society is ongoing, more and more pollutants have been released to the water resources such as rivers and oceans. A drop of water is a life. As human being, we should take good care of our water; we should save water!
