The amount of water the earth can supply life on land is less than 1% of its total water.
Freshwater resources are an important part of the earth’s resources.
Although 75% of the earth’s surface is covered by sea water, it cannot be drunk or used for irrigation. The amount of water on the earth is distributed like this: the ocean accounts for 97.2%, icebergs and glaciers account for 2.15%, and groundwater accounts for 0.31%.
Lakes accounted for 0.009%, the atmosphere (water vapor) accounted for 0.001%, while rivers and streams accounted for only 0.0001%. Among them, only groundwater, lakes, rivers and streams can be used by people, animals, and plants. This is Say: The amount of water the earth can supply life on land is less than 1% of its total water. It can be seen that freshwater resources are limited and precious, and its pollution will further reduce the amount of freshwater available for animals, plants and humans, so it will directly Affect the survival of life on earth.
