Water scarcity is indeed the outcome of large and growing population. Increase in population puts strain on resources including water. People living in an area require water for their various activities, and more the number of people more the consumption.Furthermore, wastage and indiscriminate use of water has worsened the condition.
There is no substitute of potable water. Increasing population depletes ground water and other water sources. Increase in population also augments speedier economic development, straining the water resources further. Areas with high density of population therefore witnesses intense waters scarcity. At time, such scarcity drives people to marginal areas, in turn draining water resources in such areas as well.
