Drinking water is less than 1% of the total water available on Earth. The available drinking water is converting into greywater and it is being polluted by human activities day by day on earth. The sources of available drinking water are glaciers, rivers, ice caps, groundwater, and water in ponds, lakes, etc. The population on the earth is growing day by day. The result of the growing population and increase in pollution is that the temperature due to global warming is increasing day by day. Due to the rise in environmental temperature, the glaciers are melting and the sources of fresh water in mountains are decreasing. The available drinking water is also decreasing day by day. We are using groundwater for our day-to-day activities i. e. for drinking purposes, sanitation purposes, Industrial use, and irrigation purpose. Due to all of these activities, the groundwater is also decreasing day by day.
The waste of factories and the waste of cities is now polluting river water, groundwater, lakes, and ponds water. Due to that, the drinking water is decreasing and it is an alarm for all of us that we must work to save water on our beautiful planet Earth. All of us must stop water pollution activities immediately and must save water in our day-to-day activities. We also must harvest rainwater as much as possible. The rainwater recharges our freshwater resources. We may harvest rainwater through Big Dams, Ponds, Lakes, wells, and underground storage tanks. Rain Water may recharge our groundwater to a large extent and may provide water to us throughout the year. The construction of Big Dams may solve our problems of floods and may provide water for irrigation throughout the year.
India is having rain-affected areas and we also face losses due to floods in most parts of the country. We also face drought in some parts of the country. The problem of floods and Drought may be solved by the construction of Big Dams in most parts of the country. Our Govt must make it mandatory that every House must have a rainwater harvesting tank at the bottom of the Houses. The water from the storage tank may be used for watering plants, washing floors, and toilets, and washing clothes. These practices may save water for our future. Our save water awareness activities may also save water for our future. We must save water in our daily activities like brushing, bathing, clothing, and washing utensils. We must save water by using Dry toilets and low-capacity systems. We may do one more activity in our homes if we connect all of our wastewater outlets to a storage tank then it may not go to waste but may be used to recharge the groundwater. We all must save water to save the future otherwise life on the earth may be in danger.
