Pollution in Africa
Africa is one of the most polluted continents in the world. Africa faces huge
challenges with multiple issues that adversely affect public health. One major challenge is the ability for both rural and urban Africans to access a clean water supply. It’s important to remember that pollution is very dangerous, but it’s also preventable. Water pollution in South Africa is caused by various industries, including the mining industries as well as the urbanization of people moving to cities in search of jobs or a better life. Because South Africa is rich in natural resources, mining and oresmelting industries do pose a threat to the pollution of underground water. Heavy metals such as zinc, lead and cadium, is spilled into rivers and, in the end, lands in the underground water system. Oils and petrol also pose a threat. Many gas stations store their petrol tanks underground. A crack or a leak can cause these chemicals to end up in the underground water streams. Paper mills use a lot of water and have a lot of wastewater in return. This water contains chemicals such as chlorine.
When it comes to
activities, untreated feces of animals can be washed into rivers. While you might think that this natural product cannot really cause harm, large amounts can pollute the water.
Sewerage systems sometimes leak into rivers or, with pipes bursting, into the underground water system. This is also a pollutant that can cause illnesses. Phosphates, also found in soaps, can cause water pollution if sewerage is not effectively treated. Phosphates causes water plants to grow faster. As these water plants grow faster, the water becomes overcrowded and the plants suffocate each other. The decomposing algae then use more oxygen and fish and other water life is ...
