Trees are important to the ecosystem for several reasons. Without trees, human life could not exist on Earth.
According to the Community Forest Guidebook, 100 trees remove about five tons of CO2, and 1000 pounds of other pollutants within their lifetime. CO2 is toxic to the human body so it is important for trees to remove it.
The pollutants that 100 trees remove in their lifetime also include 400 pounds of ozone and 300 pounds of particulates. This is crucial for those people who suffer from respiratory disease.
Especially in urban areas, trees are able to reduce ambient temperatures. Carbon dioxide, nitrogen and other pollutants can cause a “heat-island effect.” However, trees are able to reduce the heat by 5 to 8 degrees.
Water and Soil
After storms, trees are able to trap large amounts of water in their leaves, trunks and branches. The Community Forest Guidebook says that for every 1,000 trees, storm water run-off is reduced by one million gallons.
Trees provide shade that is necessary for keeping animals from the heat outdoors. Trees also provide a home for many types of animals.
