• Trees cut down noise pollution by acting as sound barriers. • Tree roots stabilize the soil and prevent erosion. • Trees improve water quality by slowing and filtering rain water, as well as protecting aquifers and watersheds. • Trees provide protection from downward fall of rain, sleet, and hail, as well as reduce storm run-off and the possibility of flooding. • Trees provide food and shelter for wildlife. • Trees located along streets act as glare and reflection control. • One tree produces nearly 260 pounds of oxygen each year. • One acre of trees removes up to 2.6 tons of carbon dioxide from the atmosphere each year. • One acre of full-grown medium-sized trees removes approximately 6 tons
of pollution from the air each year. • The death of one 70-year-old tree would return over three tons of carbon to the atmosphere. • In the U.S., there are about 747,000,000 acres of forested land; that's about a third of the U.S. • Trees provide shade and shelter, reducing yearly heating and cooling costs by 2.1 billion dollars. • Shade trees can make buildings up to 20 degrees cooler in the summer. • Since the early 1940s, the United States has been planting more trees
than it harvests and today has far more trees than in the 1920s.
