A Wildlife sanctuary is the natural habitat of the animals. They are preserved and no illegal activity like hunting and poaching is allowed.
(c) Endangered species: These are the species that are on the verge of extinction. If we make efforts, we can prevent them from extinction
Extinct species are those which have already become extinct due to some factors. Some of the extinct species are:-
- Dodo
- Stellers Sea Cow
- Tasmanian Tiger
- Great Auk

Question 3: Discuss the effects of deforestation on the following:
(a) Wild animals
Forests are home to different species of wild animals. They are their homes. When forests are removed the wild animals are affected badly. They lose their habitat and are forced to wander to new places.
(b) Environment:
Environment is badly affected due to deforestation. The forests cover maintains the ecological balance. This balanced gets disturbed when forests are removed. It can also lead to an imbalance in the amount of CO2 as plants intake CO2. This can lead to an increase in temperature.
(c) Villages (Rural areas)
Villages which are close to forests are dependent on forests for various needs. When the forests are cleared the wild animals of the forest like tiger, snake etc. they may be forced to run towards the rural areas. They may kill innocent villagers.
(d) Cities (Urban areas)
Urban areas experience side effects in an indirect manner. They experience an increase in temperature and poor air quality.
(e) Earth: Mother earth is made from the flora and fauna. If the forests are cleared various changes occur on earth.
(f) The next generation: The next generation may face increased pollution, global warming etc. They may not be able to see nature’s beauty if we keep destroying nature.
Question 4: What will happen if:
(a) we go on cutting trees.
(b) the habitat of an animal is disturbed.
(c) the top layer of soil is exposed.
Ans 4:
(a) If we go on cutting trees for our own interests then the natural habitat will be disturbed. Trees provide shelter, the wildlife will be disturbed. Trees maintain a balance of the gases in the atmosphere. CO2 will increase causing an increase in global warming. The wild animals will move towards the cities and villages.
(b) If the habitat of animal is disturbed then animals will start moving towards cities and villages. Wild animals may kill people if they feel danger. It will disturb the balance of life. Human life will also be affected.
(c) If the top layer of the soil is exposed, it may become infertile. The soil will lose its quality and the land will become barren.

(c) Tribal people live in forests and they are dependent on the jungle for their needs.
(d) Causes of deforestation are caused due to the greed of humans. They want to make more industries on forest lands
The consequences of deforestation are extinction of wildlife, plant life is affected, increase in pollution and global warming, villages dependent on forests are affected.
(e) Red Data book is the book in which record of all endangered species of plants and animals is maintained.
(f) Migration means movement from the present place of living to other places. This happens with animals and birds. Birds fly from one location to another when the season changes. They do this to enjoy a better climate.
Question 6: 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 purposes? Discuss and prepare a brief report.

4) Encouraging children to grow more plants in their surroundings. Children should be taught the importance of trees from a very young age.
Question 8 Explain how deforestation leads to reduced rainfall.
Ans 8. Plants show transpiration, the loss of water from aerial parts of the plants. The water evaporates and helps in the formation of cloud. The cloud then leads to precipitation. When clouds wil not be formed, rainfall will be impacted. This will lead to less rainfall in the region. So, forests are indirectly important for the rainfall. We should avoid deforestation.
Question 9. Why should the paper be saved? Prepare a list of ways by which you can save paper.
Ans. Paper is made from trees. If we do not reuse paper then more trees will be cut for production of new papers. So, we should save paper and reuse it wherever possible.
