Q47. How can you contribute to the maintenance of green wealth of your locality? Make a list of actions to be taken by you.

Ans. List of actions

                          i.        I can help in maintaining the green wealth of my locality by taking care of the plants and trees growing in or around my locality.

                        ii.        I can plant more and more plants in my locality.

                       iii.        I can also encourage the people in my locality to plant more trees by educating them about the importance of growing trees.

                       iv.        I can make children of our locality aware of the effects of deforestation and its effect on our environment and on our planet.

Q48. In order to meet the ever-increasing demand in factories 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 forests for our survival, from the air we breathe to the wood we use. Besides providing habitats for animals and livelihoods for humans, forests also offer watershed protection, prevent soil erosion and mitigate climate change.

Yet, 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.

Q49. Why should paper be saved? Prepare a list of ways by which you can save paper.

Ans. It takes 17 full grown trees to make one tonne of paper. Therefore, we should save paper. By this we not only save trees but also save energy and water needed for manufacturing paper. Moreover, the amount of harmful chemicals used in paper making will also be reduced.

Ways by which we can save paper

                         i.        Buy recycled paper products.

                        ii.        Use both sides of a piece of paper.

                       iii.        Reuse gift bags, wrapping paper and newspaper.

                       iv.        Recycle paper we can't reuse.

                        v.        Follow the golden rule: think before we print.

                      vi.        Use a handkerchief instead of tissues.

         vii.        Use an erasable board for note taking and reminders at home.

Q50. What are the advantages of reforestation?
Or
What are the benefits of reforestation?

Ans. Benefits of reforestation

                          i.        Help to maintain Oxygen Carbon dioxide balance.

                         ii.        Prevents soil erosion and floods.

                        iii.        Maintain water cycle.

                        iv.        Helps maintain the temperature in the local environment.

                         v.        Increase rainfall in an area.

                        vi.        Produces a large quantity of raw materials for industry such as paper industry, timber trade etc.

          vii.        Increases the area of earth under forests which is good for the conservation of wildlife.

          viii.        Combat climate change.

Q51. What are the various measures which can be taken to conserve forest and wildlife?

Ans. Steps

1. Some of the laws should be made to ban the killing or capturing of endangered animals or birds. It should be made a punishable offense.

2. The more number of National Parks and Sanctuaries should be established for preserving the natural habitats of wild animals and birds throughout the country.

3. Special attention should be paid even by us also to the conservation of endangered species of wild animals and birds to prevent their extinction altogether.

4. The unauthorized cutting of forest trees for timber and wood for fuel should be stopped immediately.

5. In case of the authorization of the Government for felling of trees, then the equal area of land should be planted with sapling of trees to make up for the loss in the long run.
