What is one main contribution forests make to the environment?

One main contribution forests make to the environment is carbon sequestration. Forests help regulate the Earth's climate by absorbing carbon dioxide (CO2) from the atmosphere and releasing oxygen (O2) through photosynthesis. Trees and other plants in forests absorb CO2 from the air and use it to build their tissues, effectively removing it from the atmosphere. This process of carbon sequestration helps mitigate the effects of greenhouse gas emissions and slow down the pace of climate change. Forests also play a crucial role in maintaining the balance of oxygen and carbon dioxide in the atmosphere, which is essential for sustaining life on Earth.
