Trees can add value to your home, help
cool your home and neighborhood, break the cold winds to lower your
heating costs, and provide food and shelter for wildlife. The net
cooling effect of a young, healthy tree is equivalent to ten room-size
air conditioners operating 20 hours a day.
Landscaping, especially with trees, can
increase property values as much as 20 percent. One acre of forest
absorbs six tons of carbon dioxide and puts out four tons of oxygen.
This is enough to meet the annual needs of 18 people.
There are about 60 to 200-million
spaces along our city streets where trees could be planted. This
translates to the potential to absorb 33 million more tons of CO2
every year, and saving $4 billion in energy costs. Trees properly
placed around buildings can reduce air conditioning needs by 30 percent
and can save 20–50 percent in energy used for heating.
In laboratory research, visual exposure
to settings with trees has produced significant recovery from stress
within five minutes, as indicated by changes in blood pressure and
