How does deforestation impact the carbon cycle?

Deforestation significantly impacts the carbon cycle, primarily by decreasing carbon absorption. Forests play a crucial role in absorbing carbon dioxide from the atmosphere during photosynthesis. Trees take in CO2, a major greenhouse gas, and store carbon in their biomass. When forests are cut down or burned, not only does this carbon storage capacity diminish, but the release of stored carbon back into the atmosphere occurs, exacerbating greenhouse gas levels.

The reduction in forested areas means that there are fewer trees to absorb CO2, leading to less effective regulation of atmospheric carbon levels. This alteration disrupts the balance of the carbon cycle and contributes to global warming, as increased concentrations of CO2 in the atmosphere enhance the greenhouse effect. Therefore, the correct response emphasizes the negative effect deforestation has on carbon absorption, helping to illustrate the interconnectedness of ecosystems and climate health.
