Fresh water is naturally occurring water on the Earth ‘s surface in ice sheets, ice caps, glaciers, ponds, lakes, rivers and streams, and underground as groundwater and underground streams. Fresh water is generally characterized by having low concentrations of dissolved salts and other total dissolved solids. The term specifically excludes seawater and brackish water. A human body can survive 8-14 days without water depending on the person. First of all our very existence will be in danger in the absence of fresh drinking water.
Besides we will not get the much needed source of irrigation for our fields and as a result there could be lot of scarcity of food. So we will face a situation of food crisis. Water running in rivers is tapped and big dams are constructed and hydropower is produced. Moreover river transport system is not possible in case water stop flowing in rivers. Although plenty of water is available in oceans but that is not fit to be consumed by human beings as it is salty.
At last in situation of extinction of fresh water resources, human beings will have to desalinate the sea water which is very costly affair. Lot of poor people will die as they will not be able to afford this type of water obtained through desalination plants. Moreover many types of diseases may occur due to consumption of sea water. In nutshell human beings will face a very difficult time in case they have to line without fresh water. Water is a finite resource which means that the total amount of water in the planet is only limited.
Its supply remains the same and yet human population recently grows resulting to a decrease of available amount of freshwater per person. The relatively small amount of available freshwater elaborates on how critical it is for everyone to help preserve and maintain clean, healthy lakes and streams, our sources of water. Water is mostly now being wasted because it is under-priced. We do not realize the significance of it. Also, the uneven distribution of water resources has led to the stage of scarcity in a number of regions.
Freshwater provides water for drinking, sanitation, agriculture, transport, electricity generation and recreation. It also creates habitats for a diverse range of animals and plants. There is no way we can live without freshwater supply. Our freshwater resources could eventually deplete if not protected now some way. Truth is we cannot live or function on a daily basis without the use of freshwater supply. It circulates and goes through our bodies, replenishing nutrients and carrying away waste materials. Now think of the scenario where human beings have to live without water.
