Approximately three hundred twenty-six million trillion gallons of water exist on Earth; not all water is fresh. Water from the oceans makes up 97 per cent of the planet’s water. The other one per cent is in surface water, rivers, lakes, streams and ponds. The rest is water stored underground.

There are many fresh water sources on Earth, but most of it is stored in groundwater and glaciers. These are the largest reservoirs of fresh water on Earth. However, most of this water is freshwater to be drinkable or too salty to grow crops. It is also a finite resource.

The United Nations reports that water consumption has increased twice as fast as population growth. One-third of the world’s population lives in “water-stressed” countries. These countries have an annual average of 20 per cent more water use than the available supply.

The average salinity of water on Earth varies by location, with saline lakes containing a high salt concentration. These lakes are landlocked bodies of water, such as the Caspian Sea. These lakes are only 0.008% of the total water on Earth. Saline lakes are not a globally significant water source. The only way that water can exit saline lakes is through evaporation. It’s essential to prevent water from flowing into the oceans.

The drinkable water is only fresh water & its stock is fastly down due to wastage drinkable water in the city area. Ninety-seven per cent of all Earth’s water is salt water, which is not drinkable. Glacier ice at the North- and South Poles accounts for two percent of all water on Earth. This ice could be melted to make fresh water.

Only 1% of the water in the world is fresh water. This small amount of water is used for drinking, transport, heating, cooling, industry, and other purposes.
