Trees absorb and block noise and reduce glare. A well placed tree can reduce noise by as much as 40 percent.
Fallen tree leaves can reduce soil temperature and soil moisture loss. Decaying leaves promote soil microorganism and provide nutrients for tree growth.
Trees help settle out and trap dust, pollen and smoke from the air.
Trees create an ecosystem to provide habitat and food for birds and other animals.
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)
An acre of trees absorb enough carbon dioxide in a year to equal the amount produced when you drive a car 26,000 miles.
Trees can help offset the buildup of carbon dioxide in the air and reduce the ” greenhouse effect.”
A tree can add music to your life by attracting birds and other animals.
A tree can provide pleasant smells.
