debate on life of human beings without fresh water
[ negative side (life is impossible without fresh water) ]
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.
