Deforestation and Carbon Sink Capacity

Mark
< Prev
Next >

Which of the following findings would best support the conclusion that deforestation significantly reduces a forest’s capacity to function as a carbon sink?

A

A study calculating the definite integral of CO2 absorption rates over time in forested areas, which reveals a marked decrease in total carbon sequestration following widespread deforestation.

B

Observations that suggest an increase in CO2 absorption after deforestation, contradicting the expected reduction in carbon sink capacity.

C

Measurements indicating that deforestation has little to no impact on the carbon budget, implying that CO2 absorption rates remain nearly constant regardless of tree cover.

D

Data showing that while deforestation may alter local microclimates, the overall carbon sink capacity of the forest remains unchanged, thus not requiring integration of CO2 uptake rates.
