Question 1
1.

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?

Using what you learned from the video, complete the box model.
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?
The amount of carbon that forests are able to remove have increased over time.
True
False
Which forest has been essential for carbon storage?
Black forest
Olympic national forest
Amazon rain forest
What is the primary cause of deforestation in the Amazon rain forest?
Logging
Slash-and-burn land clearing
Tourism
Where is most of the carbon in a boreal forest stored?
Frozen underground
Snow
Tree trunks
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?
Positive feedback loop
Negative feedback loop
Not enough information
Boreal forests are not likely to switch from a carbon sink to a carbon source.
True
False
