Forests are important for carbon sequestration because trees absorb carbon dioxide during photosynthesis and store the carbon in their biomass and in the soil. This helps to reduce the amount of carbon dioxide in the atmosphere, which is a greenhouse gas that contributes to climate change. Forests act as a natural carbon sink, helping to mitigate the impacts of human activities that release carbon dioxide into the atmosphere, such as burning fossil fuels. By preserving forests and promoting reforestation, we can enhance carbon sequestration and help combat climate change.
