| Thick forests with 70 foot high trees in humid tropical areas of Africa | Tropical Rainforest |
| Farming just enough to feed you and your family | Subsistence farming |

| People have to move when the soil can't support life anymore. This causes more desertification when they repeat their activities and overcrowding in cities. Famines can also occur. | How does desertification impact Africa? |
| Widespread shortages of food | Famine |
| Long period of abnormally low rainfall | Drought |
| Warm and humid | Tropical |
| having a lot of moisture in the air | Humid |

| Pollution caused by fertilizers and pesticides are washed into the water supply | Agricultural runoff |
| a long period of time during which there is very little or no rain | Drought |
| pollution caused by chemicals and other waste from factories | Industrial waste |
| Lack of fresh water can create conflict as nations compete for fresh water resources | Water wars |
| done by cutting down and burning trees and plants in order to clear an area of land and grow crops on it for usually a brief time | Slash and burn agriculture |
| the gradual destruction of something by natural forces (such as water, wind, or ice) | Erosion |
| Poor agricultural pracice that allows animals to excessively eat grass or other plants that are growing which causes damage to grassland | Over grazing |
| Lack of water due to not having the money to keep the water clean | Economic water scarcity |
| Lack of water because there is little to no fresh water available | Physical water scarcity |
