In the previous article, it was mentioned that water pollution can results in human, wildlife and marine life deaths. The effects can be mild or heavy depending on the type of substance that pollutes the water as well as on the concentration of the chemicals discharged in the body of water. For example, a body of water polluted with refuses or garbages may not be as catastrophic as a pollution caused by harmful chemicals. Below are some of the effects of water pollution.

Death of marine life

The aquatic animals are the major sufferers of water pollution. The water bodies in which these chemicals and refuses are discharged into are the habitats of these animals. It is not uncommon to see dead bodies crabs, fish, dolphins, seabirds, sea gulls floating on the oceans or by the seaside whenever their habitat becomes polluted. They are not like human beings that have hospitals or that can think out a way of protecting itself anytime their habitat is polluted. They are totally defenseless. Thus, they die in huge number whenever their habitat is polluted.

Disruption of food-chains

Studies have proved that water pollution brings about the disruption of natural food chain. Tiny marine animals consume pollutants like cadmium and lead. Other big fish and shell prey on these tiny marine lives. Human beings feed on these big fish as well. The pollutants are being transferred from one living being to another in this manner. This brings about disruption in the natural food-chains.

Diseases

As mentioned above, water pollution disrupts natural food chains. When these pollutants are transferred from the marine lives to human beings, the chemicals are deposited into the body. They may have damaging effect on them. Some chemicals can reduce the quality of their lives. Besides, polluted water contains contaminants and disease causing bacteria and germs. Such bacteria and germs can cause infections and diseases such as typhoid fever, cholera, hepatitis and other illness that spread through water.

Destruction of ecosystems

The ecosystem refers to the system of biological community of interacting living being and their physical environment and how each living organism helps the other to survive. This interaction can be destroyed or interrupted by the water pollution. When the water bodies are polluted through the activities, it will not only affect the interaction of marine lives but the entire ecosystem. Human beings will be affected as well as other animals that feed on those marine lives.
