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?

Trees dying in the Amazon rainforest are an example of a feedback loop because and the loop is .
Which model best represents the relationship between the Amazon rainforest and atmospheric carbon dioxide before widespread deforestation?
Which model best represents how the relationship has changed after widespread deforestation?
Deforestation of the Amazon rainforest has become a of carbon because burning trees carbon faster than photosynthesis it.
Carbon dioxide the atmosphere.
By removing it and storing the carbon in their branches, trunks, leaves, roots, and soils, forests the Earth.
The amount of carbon that forests are able to remove have increased over time.
Which forest has been essential for carbon storage?
What is the primary cause of deforestation in the Amazon rain forest?
Scientists predict that with the loss of so many trees, the Amazon could emit carbon than it stores.
Where is most of the carbon in a boreal forest stored?
Positive feedback increases the change and leads to instability.
Negative feedback reverses the change and brings things "back to normal."
Are more fires part of a positive or negative feedback loop?
Boreal forests are not likely to switch from a carbon sink to a carbon source.
Old growth forests store carbon than young growth forests.
Healthy and thriving forests could result in carbon in the atmosphere.
