Trees are the oldest living organisms on earth.
Trees restore our air supply by producing oxygen and absorbing carbon dioxide. One tree creates nearly 260 pounds of oxygen each annually. The amount of oxygen produced by an acre of trees in twelve months can supply oxygen to18 people annually.
One acre of trees removes up to 2.6 tons of carbon dioxide yearly. Trees that are planted for shade can make buildings up to 20 degrees cooler in the summer.
By evaporating water in their leaves, trees lower the temperature of the air.
The tree roots alone can stabilize soil and prevent erosion.
A tree can improve water quality by slowing and filtering rain water, in addition to protecting aquifers.
