Explain how humans react and adapt to the limited availability of water.

One of the easiest things people can do when water is scarce is limit its use. Lawns get watered less often, or only at specific times of day. Vehicles are washed less often or not at all. In addition, when water is scarce, wastewater is reused more often if it does not contain sewage. blackwater nowadays is so much used that it contains catominations and pathogens.availiability of water can also be determined by its scarcity and lawn texture

Explanation:

In the scarcity of water, the humans should learn to conserve the available water. They should find ways to preserve the rainwater which can be used for bathing, washing and sanitation. They should find ways to build long line drainage system so as to obtain water from near and far water bodies.
