The total amount of water resources on the earth is about 65.438+0.38 billion cubic kilometers, of which 97.5% is seawater. Fresh water accounts for only 2.5%, mostly polar ice and snow glaciers and groundwater, and only 0.0 1% is suitable for human consumption.

The country with the least water resources per capita is Kuwait, located in the northwest of the Persian Gulf in West Asia, with a land area of 6,543,800 square kilometers and a population of 4,654,338+0,370.

Kuwait has a small land area. As a country bordering on the Persian Gulf, there are no rivers and lakes in China, and fresh water resources are very scarce. Even with seawater desalination, its per capita disposable capacity is only 27 liters per day.

Greenland has the largest per capita water resources in the world, and the per capita disposable water is 29 million liters per day.

Greenland's glaciers also have a special product "permanent ice". The local glacier ice contains a lot of bubbles, which will burst continuously once put into water, and it is one of the excellent cold food ingredients.
