and for shelter, trees are being continually cut. Is it justified to cut trees
for such projects? Discuss and prepare a brief report.
Ans. No. Cutting trees in order to meet the ever
growing demands of the human population is not at all justified. We depend on

despite our dependence on forests, we are still allowing them to disappear. Cutting
of trees in order to meet the ever-increasing demand in factories and for
shelter, trees will lead to global warming, soil erosion, greenhouse effect,
droughts, floods, desertification etc. The destruction of forests will disturb
the balance of nature. Hence, forests must be conserved.
