Trees
play an important role in maintaining ecological balance. Trees produce oxygen
which is essential for us to survive. If there were no trees, there would have
been no oxygen resulting in lifeless world. Trees also take away
carbon-dioxide. It gives shade and makes the environment cool. Trees are
necessary for healthy living. They also save us from natural calamities.
But
many trees are being cut down every year. This is a problem haunting the whole
world. According to the ecologists, for livable environment there should be
forest on the 25% of land area. In Bangladesh only 16% of the total land is
occupied by forests. To meet up basic needs of wood and fire wood man is
destroying forest without caring for the ecological balance. Green patches of
land are no more green. New areas of the world are becoming deserts as an
immediate effect of deforestation. In absence of trees carbon dioxide is
increasing worldwide. As a result, there is a global warming. The sea level is
rising. Any time in future the earth may be engulfed by seas. On the other hand
it leads to less rains and fall of harvest. This fall of harvest leads to
famine with the result that many people die of starvation. Again birds and
beasts will have no place to live in. Thus wild life will be extinct.
So
to save mankind deforestation should be discouraged and awareness of the
importance of trees has to be developed to keep the earth greener, cleaner and
safer for the future. The loss of trees means the loss of life. We should,
therefore, plant trees in plenty and preserve those that were planted before.
