答案
Despite the fact that 75% of the earth is covered with water, only 2. 5% is fresh water that we can use.
As is shown in the second chart, of the fresh water, 69% comes from glaciers and permanent snow cover, which means it is not within the average person’ s reach. 0.3% is soil moisture, ground ice and permafrost and swamp water which cannot be used. The fresh water people can really use is renewable fresh water from lakes and river, which only account for 0. 3 % percent of the total.
Therefore, the amount of water available for use is very limited. To cope with the global water crisis, we should improve water-saving awareness and form the good habit of saving water in every possible way. In addition, since most fresh water is stored in glaciers and permanent snow cover, it can also become a very importance source of fresh water with the advancement of technology.
