Question 7
|
(a)List four sources of water.
(b)Describe any four ways in which water is useful as an environmental resource.
(c)Highlight any three major problems resulting from water pollution.
|
This was a very popular question among the candidates and most of the candidates that answered the question performed very well. However, a few of the candidates who answered the question misinterpreted the (c) aspect of the question to “mean major problems resulting from pollution”. The major problems resulting from water pollution include:
- water borne diseases e.g. cholera;
- extinction of aquatic plant and animal species;
- shortage of clean water for domestic use;
- shortage of water for industrial use;
- ecological imbalance;
- rapid growth of water weeds;
- polluted water cannot be used for agricultural purposes;
- migration of people and animals.
