Deforestation is the cutting down or removal of large areas of trees and forests so the land can be used for things like farming, building towns, or getting wood.
Cutting down large numbers of trees weakens the whole forest’s protection, soil, water cycle, and resilience — which together cause more remaining trees to become stressed, diseased, or killed.
Think about the effects of deforestation on the Amazon rainforest and the amount of carbon dioxide in the atmosphere. How could you depict it with a box model? What arrows could you add?
