Ways to Reduce Air Pollution
Trees play a very
important role in the
environment. They
provide not only food and
shelter, but also oxygen.
Human beings and
animals breathe in
oxygen and breathe out
carbon dioxide. To make
their food, plants take in
carbon dioxide and
produce the oxygen that
we breathe. Any increase
or decrease in the amount
of these gases in the air
will affect the health of
living things. Trees help
to maintain this balance
in the air.
