In the case of forests releasing significant amounts of carbon into the atmosphere, this typically occurs when areas experience deforestation. When trees are cut down or removed, they start to decay. During the decay process, the stored carbon within the trees is released back into the atmosphere as carbon dioxide. This contributes to an increase in carbon emissions and the greenhouse effect, impacting climate change.
Deforestation not only removes trees that were actively sequestering carbon but also accelerates the release of carbon previously stored in the trees. As a result, deforestation is a major contributor to the increase in atmospheric carbon dioxide levels.
Therefore, the correct statement regarding when forests release significant amounts of carbon into the atmosphere is:
- Trees release carbon when decaying, so when areas experience deforestation, large amounts of a forest's sequestered carbon will be released back into the atmosphere.
