Trees produce oxygen and store carbon
dioxide (just opposite of humans), which helps to clean
and restore our air. They also trap pollutants, such as
greenhouse gases, ozone and particulate matter (such as
dust, smoke and pollen.)
A single, fully-grown Sycamore tree can
transform 26 pounds of carbon dioxide into life-giving oxygen
every year.
Large trees remove 60 to70 times more pollution
than small trees. Only a small portion of the Dallas area tree
population exceeds 24" in diameter.
