More than 70 percent of Earth's surface is covered with water but there is still shortage of drinking water because that 70 percent is sea water which has salt and other impurities in it. Thats a resource which needs to be purified before consuming......

Answer 2

Answer:

1. Pollution

Pollution is a major cause of water shortage. Water is polluted when industrial wastes are deposited into water bodies thus making it unfit for human consumption. Oil spillage and fecal matter also makes the water contaminated. It cannot be used for drinking. This makes it scarce.

2. Overuse of Water

When water is overused, shortage occurs. Some people use too much water especially for irrigation purposes. It therefore becomes inadequate for other equally important uses.

3. Water Wastage

Wastage of water is also a major cause of water shortage. Some people leave their taps running even when they are not fetching water. All this is lost to the ground. The resultant problem is lack of enough water.

drought

4. Drought

When drought strikes an area, there is usually no rain for a long period of time. This makes rivers to dry. Other water sources such as streams, ponds, e.t.c also dry up. People therefore do not have enough water for domestic and industrial use.

conflict5. Conflict

Conflict contributes to water shortages in areas. When people are fighting over control of water sources like rivers, some will not have access to it.

6. Distance

In some areas especially arid regions, people stay far away from oasis and other sources of water like boreholes. Traveling there takes a lot of time. It is also a burden to carry water from such distant places to homes. This discourages them from going to fetch water. The result is water shortage.

7. Restriction by Governments

Some governments especially those that govern by dictatorship may restrict citizens from accessing certain water sources.

deforestation

8. Destruction of Water Catchment Areas

Water catchment areas such as forests are continually being destroyed through deforestation to pave way for human settlement. This problem has been brought about by rapid population increase. As a result, there is not enough rain thus causing water shortage.
