Water is a prime need for human-being. From the basic level of drinking a glass of water regularly to watering a field, water is a massive part of our expenditures. There is only 0.3% fresh water available for the use of humans and other livings. Other 99% of water is unusable for humans.
There are several hotspots of water-sharing where the water of some rivers is shared with potential conflict to fulfill the regular water needs-
1- The Ganges-Brahmaputra Water- this water is used between Bangladesh and India.
2- The Nile water- this water is shared among 11 countries including Sudan, Egypt, Rwanda, Kongo, Kenya etc.
3- The Indus water- this water is shared between India and Pakistan.
4- The Tigris-Euphrates water- this water is shared among Turkey, Syria, Iraq, Iran, and Kuwait.
5- The Colorado River water- this water is shared between the United States and Mexico.
This is just a single picture where the scarcity of water is opening its mouth to swallow thirsty humans. The lack of water can cause water-wars among countries which can be a great problem in this nuclear-age. Saving the water is a big necessity for succeeding generations.
