3. TREES
Trees are essential to our world and
offer a wide range of benefits to our
environment.
The list of benefits that Trees
provide is so long that one might
believe its exaggeration, but it is
not. Reduced pollution, erosion
control, wildlife habitat, energy
saving & enhanced human comfort
are all well known long term
consequences of Tree Planting.
Planting Trees is one of the
cheapest and most effective ways to
bring about widespread
improvement in the environment &
the quality of life of an area. Even
in the areas with over concreted
land & water shortage of a mega
polis like Delhi, plants & Trees play
a huge rate n regulating
temperature and air quality.
