+        Forests play a crucial role in mitigating climate change. They act as carbon sinks, absorbing carbon dioxide from the atmosphere through photosynthesis and storing it in their biomass and soil. Deforestation, on the other hand, releases carbon dioxide into the atmosphere and reduces the planet's capacity to absorb carbon. Therefore, protecting and restoring forests is an important strategy for mitigating climate change.
