Trees resuscitate our world through
photosynthesis, and capture pollutants and other detrimental
by-products of our mechanized lifestyle in exchange for oxygen.
This barter alone highlights the special role of trees in urban
life, where population and commercial density generate an excess
of harmful elements into the air we breathe.
The leaves, bark, trunk and root systems of trees act as
natural filters to sequester carbon, and inhibit production of
CO2 (the primary greenhouse gas).
- Trees also retain the two major components of acid rain
and ozone pollution, nitrogen oxide and sulfur dioxide.
- Just 100 mature trees can capture five tons of carbon
dioxide from the atmosphere annually.
- A healthy, mature ash tree produces about 260 pounds of
net oxygen each year.
- That’s roughly 2/3 the average oxygen consumption per
typical adult.
- A single acre of trees can generate enough oxygen daily
for 18 people.
- Trees efficiently intercept particle matter, such as
pollen, dust, smoke and ash.
