Read about africa's two greatest environmental concerns: desertification and the spread of disease. choose one of these concerns and write a short paragraph about its impact on africa. what has caused this problem to occur, and how has it impacted people who live there?

Food-borne diseases caused by poor hygiene and a lack of clean water, as well as respiratory ailments produced by atmospheric dust from wind erosion are all potential health effects of desertification.

Africa's development has been hampered by the spread of illness. The disease can spread at startling rates when people share drinking water, as witnessed in the recent Ebola virus outbreak. Hospitals are another factor to consider. Due to a lack of infrastructure and a failure to exploit available resources, poverty is endemic in many parts of Africa. There are few hospitals, and those that are open have filthy facilities and overworked employees. The awful reality is that sickness will likely persist until their economy improves.
