If every American family planted just one tree, the amount of carbon dioxide in the atmosphere would be reduced by one billion pounds annually. This is almost 5% of the amount that human activity pumps into the atmosphere each year.

Trees remove carbon dioxide from the air and replace it with oxygen. In one year, an average tree absorbs carbon dioxide equal to the amount produced by driving a car 26,000 miles and gives out enough oxygen for a family of four to breathe for a year.

Trees improve water quality by filtering sediment, chemicals, and other pollutants from runoff before they enter a stream.

The roots of trees planted along streambanks help bind soil particles, thus stabilizing the bank and reducing erosion.

Trees smooth out the harsh and straight lines of buildings.

Trees, planted in harmony with the home or building, add property value.

Trees buffer noise and screen out unsightly views.

Trees provide shade for cooling parking lots, driveways, sidewalks, and vehicles.

Trees provide nuts, fruits, and other food for humans and wildlife.

Apartments and offices in wooded areas rent more quickly and tenants stay longer.

Trees help relieve stress and reduce recovery time for sick and injured people.

Trees promote harmony among people reducing acts of agression and crime.
