Water Resource Challenges – Essay Example

Appendix E Water Resource Challenges Review Ch. 10 and 11 of your text, then complete the following: Provide at least three freshwater and three ocean water resource challenges by filling in the following table. Then, respond to the question that follows:
Freshwater Resource Challenge
Description
Pollution of Lakes and Reservoirs
The loading of organic wastes from industrial, domestic and agricultural activities into the lakes and other water reservoirs has resulted in degradation of water quality.
Water shortage
Increasing urbanization and rise in population has resulted in water shortage across the world.
Inadequate water sanitation
Many people across the globe lack access to clean and safe drinking water that has caused several health hazards and death.
Ocean Water Resource Challenge
Description
Oil spills
Oil from spills and those from industrial wastes entering the rivers and drains are damaging the ocean marine environment to a large extent.
Sewage disposal
Untreated sewage water from many parts of the world entering the ocean is reducing the water quality of the oceans.
Dumping of toxic chemicals
Dumping of toxic chemicals and radioactive wastes in oceans has threatened the lives of the organisms living in the oceans which also indirectly affect the human population when such organisms are consumed.
In 200 to 300 words, respond to the following: Choose one fresh or ocean water resource challenge and describe in detail why the issue has become a problem and how human activities have contributed to the problem.
Oceans occupy a large portion of the earth’s surface and support a wide variety of life forms. However man-related activities such as oil spills, sewage disposal and dumping of toxic chemicals are now threatening the existence of these life forms. The most important of these are the toxic chemicals as dumping of chemical and radioactive waste can cause permanent damage to the ecosystem as the half-life of such chemicals is long and when they enter the food chain they can cause serious health problems to both the marine organisms and mankind. The low rate of breakdown of these chemicals increases their concentration within the body of the organisms that consume them and these chemicals pass through the food chain when the small organisms are consumed by larger organisms. Consequently animals higher up in the food chain can have higher concentration of these chemicals and finally people get contaminated by consuming such organisms. The medical fraternity has identified several health issues such as cancer and fertility and immunological problems that can be caused by consumption of such contaminated foods. Thus apart from endangering the lives of the marine organism’s drainage of toxic chemicals into the oceans can have a reverse effect on the health of humans. Thus humans alone can put an end to this problem by avoiding disposal of harmful chemicals into the ocean water.
