Trees absorb carbon dioxide and potentially harmful gasses, such as sulfur dioxide, carbon monoxide, from the air and release oxygen.
◦ One large tree can supply a day's supply of oxygen for four people.
◦ A healthy tree can store 13 pounds of carbon each year ----for an acre of trees that equals to 2.6 tons of carbon dioxide.
◦ Each gallon of gasoline burned produces almost 20 pounds of carbon dioxide.
◦ For every 10,000 miles you drive, it takes 7 trees to remove the amount of carbon dioxide produce if your car gets 40 miles per gallon (mpg); it will take 10 trees at 30 mpg; 15 trees at 20 mpg; 20 trees at 15 mpg; and 25 trees at 12 mpg)
