Forest ecosystems play a crucial role in regulating the global carbon cycle and climate through a process called carbon sequestration. Trees absorb carbon dioxide from the atmosphere during photosynthesis and store it in their biomass. This stored carbon helps to reduce the amount of CO2 in the atmosphere, which in turn mitigates the greenhouse effect and helps regulate global climate patterns. Additionally, forests release oxygen as a byproduct of photosynthesis, further contributing to a balanced atmospheric composition. The preservation and restoration of forest ecosystems are essential for maintaining a stable climate and mitigating the impacts of climate change.
