Water the elixir of life

Life on earth depends upon water. Without it no life form can exist. Water is the elixir of life. Around 71% of earth’s surface is covered with water. Out of the total water available to us on the earth, nearly 97.5 percent is saline water. Remaining 2.5 percent is freshwater. More than 70% of this freshwater is located in polar ice caps & as soil moisture, making it directly inaccessible for human use. It means that amount of freshwater in the globe which is only 0.003% is available to sustain human & animal life activities & all ecosystems. This small amount of water found in lakes, rivers, reservoirs,, shallow ground water sources gets continuously renewed through nature’s water cycle. Use of water has been growing at a fast pace and it is continuously to shoot at an alarming speed in many regions of the world. Whereas most of freshwater flowing in the river basins is decreasing and in near future no water would be available for human use. Growing population and speedy urbanization is putting pressure on freshwater resources and distribution of usable freshwater. It is our responsibility to address the problem of increasing pollution of water resources. Adoption of appropriate agriculture practices & cautious use of water resources with understanding of nature’s water cycle will help to maintain the water balance. The global warming also affects our water resources and water demands. To gain full benefits of clean water and sanitation we need to emphasize upon the people, the link between diseases and unsafe hygiene practices. This video attempts to convey the water scenario of the region, understanding the water cycle, human responsibility to maintain the freshwater resources and simple tips about cleanliness to lead a better and healthier life.
