Environmental Issues of Africa
Tropical Rainforest
• Thick vegetation with high annual rainfall
• Home to unique wildlife and plants
• Endangered by deforestation (clear cutting trees)
Deforestation• Trees are important because– Produce oxygen -Paper– Maintain ground soil -Heat– Cool the ground -Building materials– Prevent erosion– Produce food• Fruit• animals
Sahel
• Large strip of land that borders the Sahara Desert
• Rich in mineral resources• Valuable farm land
Sahel
Savannas
• Grasslands in Africa• Home to the large game animals of Africa• Most Farm lands in Africa• Poaching-illegal hunting of game animals
Savanna
Desertification-Spreading of the desert
Causes• As trees are cut down
they don’t grow back• Over farming of the
land• Poor soil leads to
desertification• The desert takes over
Consequences• Less food is produced
for the people• Resulting in famine (no
food to eat)• Famine =
starvation=death
Desertification
• Deserts are taking over valuable farmland in the Sahel and the Savannas
Clean Water
• Needed for health and sanitation• Dirty water = diseases• Lack of clean wash water = skin and eye
infections• Water-borne diseases spread by parasite• Mosquitoes and other insects carry diseases(Malaria)
The Problem
• Need water– Drinking -Cooking– Farming -Washing– Animals -Bathing
People have to live near water to survive but it can kill them
Summary
• Describe in a paragraph the environmental problems in Africa. Include deforestation, desertification and clean water.
