Carbon sequestration in forests is a natural process where trees and plants absorb carbon dioxide from the atmosphere during photosynthesis and store it in their roots, trunks, branches, and leaves. This stored carbon remains in the forest ecosystem for an extended period, helping to mitigate the effects of climate change by reducing the amount of carbon dioxide in the atmosphere. Additionally, as trees grow and mature, they continue to sequester carbon, making forests vital in the global carbon cycle.
