Forests play a crucial role in maintaining the health of the planet in various ways. They act as carbon sinks by absorbing carbon dioxide from the atmosphere, helping to mitigate climate change. Forests also support biodiversity by providing habitats for numerous plant and animal species. Additionally, they help regulate the water cycle, prevent soil erosion, and contribute to the production of oxygen through photosynthesis. Overall, forests are essential for maintaining the health and balance of the planet's ecosystems.
