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
Over farming
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
Protect Rainforests
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

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

10. Water Pollution Effects
Diseases
Lower life expectancy
Contaminated Food

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

12. 4. Unequal Distribution of Water
Dams
Location of cities

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
