It is common knowledge that the world is covered with water. In fact, the continents are like big islands in vast oceans. Over 75% of the land is covered with water. There is no shortage of water on earth. The country boasts some of the largest water bodies, including oceans, lakes and rivers, which cover about two-thirds of its surface. Despite the fact that three quarters of the country is made up of water, less than 3% of the water is fresh water without salt. In addition, existing fresh water is not fully available for human consumption.
How much fresh water is there on earth?
As mentioned earlier, about 2.5% of groundwater is fresh water. Only 31% of the fresh water available on land is available. About 69% of fresh water is found in the form of ice caps and glaciers in places like the Antarctic and Greenland glaciers, which further reduces the amount of drinking water available. So, if only 31% of fresh water is available for drinking, that means 31% of 2.5% = 0.00775, which is less than 1%. Therefore, less than 1% of the earth’s water is drinkable. In some areas, the glacier often melts in the summer giving extra drinking water. However, the amount of water from melting glaciers is not enough to increase the available fresh water to over 1%.
Where is fresh water available?
Almost all available fresh water (except glaciers) is groundwater. Groundwater comes out and feeds streams and saturated swamps. It serves as a reservoir that can also be used for a variety of agricultural and industrial applications. Groundwater provides about 40% of drinking water.
Another important source of drinking water is surface water. Surface water is retained in lakes, rivers, dams and streams. Although rivers and dams are crucial for water supply, they contain only 1% fresh water. Over 0.001% of fresh water is contained in the form of atmospheric vapor, a small amount due to its important role in time. However, atmospheric water is recycled between the atmosphere and the earth’s surface several times a year, resulting in rain and snow. Rain and snow are crucial for rebuilding surface waters
How many people do not have access to safe drinking water?
Of the less than 1% of drinking water available, most third world countries do not have the resources needed to provide clean and clean drinking water to their people. According to a 2008 WHO report on drinking water and basic sanitation, some 885 million people, one-eighth of the world’s population, do not have access to clean water. Over 3.6 million people die each year from diseases caused by unclean drinking water.
What is the future of fresh drinking water?
Although surface water is an important source of drinking water, surface water depends on various variable rain patterns, making it unreliable. Protection and management of groundwater and surface water is an important task to ensure the availability of drinking water. No one can create water anymore. But by managing water sources and distribution systems, people maximize available water and use it from every drop.
