1 Environmental Issues of Africa
SS7G2 The student will discuss environmental issues across the continent of Africa. a. Explain how water pollution and the unequal distribution of water impacts irrigation, trade, industry, and drinking water. b. Explain the relationship between poor soil and deforestation in Sub-Saharan Africa. c. Explain the impact of desertification on the environment of Africa from the Sahel to the rainforest.

2 4 Big Problems Desertification Deforestation Water Pollution
Unequal distribution of water

3 1. Desertification Definition: Process of previously fertile land becoming desert CAUSES: Logging Overgrazing Drought * The Sahel is experiencing severe problems with desertification

4 Effects of Desertification
Hunger and hardship Less able to grow food Desert is expanding

5 Solutions Educate farmers Plant trees

6 2. Deforestation Definition:Process of cutting down of trees and other vegetation Causes: Slash and burn Over grazing Farming * Rapid deforestation is occurring in the Sahel and in Africa’s west and central tropical rainforests * Nigeria is losing rainforests at the fastest rate – Has lost 55% of original forests

7 Effects of Deforestation
Effects 1.Poor soil 2. Starvation 3. Destroys habitats

8 Solutions of Deforestation
Replant trees Laws against cutting Deforestation Video

9 3. Pollution Garbage Pesticides Human waste
Water pollution is a huge problem in Africa – major cause is not industry, caused instead by natural environment Garbage Pesticides Human waste

10 Water Pollution Effects
Diseases Lower life expectancy Contaminated Food

11 Water Pollution Solutions
Water treatment plants Appropriate disposal of waste Brainpop

12 4. Unequal Distribution of Water
Dams Droughts Landlocked Countries

13 Effects of Unequal Distribution
Less Drinking Water Farming Suffers Economy Suffers

14 Solutions to Unequal Distribution of Water
Wells Canal System Move closer to water
