A single 30-meter-tall mature tree can
absorb as much as 22.7 kilograms (50 pounds) of carbon dioxide in a year, which
over it’s lifetime is approximately the same amount as would be produced by an
average car being driven 41,500 kilometers (25,787 miles). The same tree could
also produce 2,721 kilograms (5,998.78 pounds) of oxygen in a year, which is
enough to support at least two people. According to the University of
Melbourne, because trees grow faster the older they get, their capacity for
photosynthesis and carbon sequestration increases as they age.
