. Is the Threat of a Global Water Shortage Real?

Water is the most important need to not only human being but also Earth. Nowadays, metropolises meet the shortage of water and other water problems. Many scholars debate about this issue. They are separated by two groups. One group insist on a global water shortage is happening and the other group is water shortage is unreal. I strongly agree with this statement. In my opinion, we are going to face the global water shortage soon.

The advertisements emphasize that we should spare water made by kobaco in Dec, 2009. Moreover, Kim because of global warming, it makes to face water shortage faster.

Therefore, the amount of vaporization of water is way less than the amount of rainfall. Even the glacier melted by hot weather, it mean the sea level is increasing. The reader might think that why developments bring water shortage? The reason is asphalt and cement are blocking water permeate into the ground. The outcomes are the “waterway is collapse and be blocked.” Therefore, the amount of underground water is decreasing. From now on whole world should spare water and make the substitutes for water.
