• Trees keep our air supply fresh by absorbing carbon dioxide and producing oxygen. • In one year, a single tree can absorb as much carbon as is produced by a car driven 26,000 miles. • Trees provide shade and shelter, reducing yearly heating and cooling costs. • Trees lower air temperature by evaporating water in their leaves. • 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. • Trees provide food and shelter for wildlife. • Trees located along streets act as a glare and reflection control.
