Solution
Water availability per person in India is declining.
This statement is true. Though water is present in abundance, fresh water is a scarce resource. Water availability is a serious problem in many regions of the world. Due to the wastage of water, deforestation, and the pollution and depletion of fresh water reserves (such as rivers and ground water), the availability of water is fast declining.
