Healthy, mature, and abundant forests are critical to a balanced environment. When there are an inadequate number of forests, the environment is slower to repair the damage done over time.  Abundant forests are essential to a healthy carbon cycle.  Burning coal, oil or even breathing creates carbon dioxide. Trees absorb carbon dioxide, fixing it in the wood fiber, while releasing fresh oxygen into the air. 

A healthy, mature oak tree produces enough oxygen for four people. Trees are also the most effective erosion control mechanism on earth.  A extensive root structure will protect the soil from water or wind erosion better than any man made substitute.
