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.

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
