Project Work
In India forests occupy approximately 30% of the landmass. Forests supply wood and many other products like gums, fibres, bamboos, medicines, honey, resins, oils, lac, shellacs, pulp, paper and, above all, pure oxygen. Nowadays, condition of forests is deteriorating due to the constant pressure of increasing human population, which causes imbalance in the forest ecosystem. This is of grave concern to all of us.
Make a forest trip along with your teacher. Visit the forest and meet the forest range officer. Then fill in the survey form.
