Page No 109:

Answer:

The following are the three main causes of deforestation.

(a) Agriculture: To feed the already vast and rapidly growing population, we require more and more land for agriculture, which is obtained by clearing forests.
(b) Forest produce: The unsustainable use of forest resources (for example, for obtaining a huge amount of forest produce such as honey, timber, fruits and rubber), without keeping in mind the restoration capacity of the forests, also leads to deforestation.
(c) Hydroelectric projects: The construction of dams for hydroelectric projects lead to the submersion of forest tracts, killing most of the plants and animals in that region.

Page No 109:

Answer:

Wildlife sanctuaries play an important role in the protection of wildlife by prohibiting the killing of animals in these areas. Animals in these sanctuaries can breed and multiply in their natural environment.

Answer:

A biosphere reserve is a protected area meant for the conservation of plant and animal life. Biosphere reserves also help improve awareness about the environmental aspects of life and eco-friendly ways of living.

Page No 109:

Answer:

It would be unethical to destroy wildlife because that would disturb the ecological balance of the forest ecosystem. A decrease in the populations of animal and plants causes disturbances in nature. Moreover, they are also living beings and have a right to live. It is wrong to harm animals for making, and trading in, animal products.

Page No 109:

Answer:

The destruction of natural habitats affects wildlife by bringing about several environmental changes that are not suitable for animals. It also causes difficulties for them in finding food and forces them to migrate in search of new habitats. Some of the affected animals perish as they are unable to adapt to the environmental changes.

Answer:

Wildlife sanctuary Biosphere reserve
It is an area where wildlife is protected from  hunters.  It is an area meant for the protection of wildlife along with the traditional life of the tribals living in that area.
Activities such as collection of forest produce and harvesting of timber are allowed.  Each biosphere reserve has three zones:
(i) Core zone: No human activity is allowed.
(ii) Buffer zone: Limited human activities, such as research and education programmes, are allowed.
(iii)Transition zone: Activities such as farming and settlements are allowed.

Answer:

People go for hunting for the following reasons.

(a) For fun and enjoyment
(b) For obtaining the skin and other useful parts of some animals
(c) For obtaining food

Answer:

Birds and animals sometimes travel long distances from their habitat, to overcome unfavourable conditions during some seasons. This movement might also be a part of the life cycle of some birds. The movement of large numbers of animals and birds over long distances is called migration.

Answer:

We would take the following measures to protect and preserve endangered species in India.

(a) Demarcating wildlife sanctuaries and national parks for protecting endangered species in their natural habitat
(b) Reducing the use of products obtained from wild plants and animals
(c) Restoring streams, rivers, ponds and other water bodies to their natural conditions
(d) Protecting migratory birds by marking out their migratory route and protecting them during the season of migration
(e) Spreading awareness about the importance of forests and wildlife and eco-friendly ways of living

Answer:

Project Tiger was started in 1973 by the Government of India with the help of international agencies. It is a conservation programme that aims at saving tigers from extinction in India. Initially, nine tiger reserves were established in as many states. These reserves occupy a total area of 13,017 sq. km. There are now 27 reserves spread across 17 states.

Page No 110:

Answer:

National parks refer to the areas that are reserved for the protection of wildlife. Activities such as foresting, grassing and cultivation are prohibited in national parks.
Sanctuaries are protected areas where wildlife is protected in its natural habitat. Private operations such as the cutting of trees for timber and the collection of other forest produce are allowed on a small scale in sanctuaries.
National parks and wildlife sanctuaries are important for wildlife management as they both protect and conserve wildlife. They provide wildlife species with their natural habitats and promote their conservation. They keep wild animals away from human activities.

Page No 110:

Answer:

Wildlife help maintain the environment as different species form important links in different ecosystems. A failure of these ecosystems leads to environmental imbalances. For example, plants are important in keeping the air clean as they perform photosynthesis and constantly supply oxygen to the air. Therefore, deforestation leads to environmental pollution and desertification. This in turn has an adverse effect on the existence of many animal species, which, because of deforestation, lose their habitats. If important plant and animal species go extinct, it might have a harmful effect on human life. Thus, rapid loss of wildlife might disturb the environment and the balance of life.

Page No 110:

Answer:

These are the parks where various species of animals and birds are kept in enclosures or cages for public exhibition. The birds and animals are taken care of by the zoo authorities. Zoos play an important role in protecting animals away from their natural habitats and creating awareness among the people about the importance of conserving wildlife.
 

Zoos Wildlife sanctuaries
Animals are kept in cages or enclosures.  Animals are set free in their natural habitats.
Zoos are built specifically for the public exhibition of birds and animals. Wildlife sanctuaries are specifically demarcated for conserving wildlife.

Page No 110:

Answer:

The following steps are proposed by scientists all over the world for saving the existing wildlife.

(a) Species that fall under the endangered, vulnerable or rare category should be given special attention.
(b) Wildlife sanctuaries and national parks should be made according to the breeding, feeding and environmental needs of various species.
(c) Streams, rivers, ponds and other water bodies should be restored to their natural conditions.
(d) Migratory birds should be protected by marking out their migratory routes.
(e) Proper education about the need for protecting wildlife should be imparted to all.
(f) People should reduce the use of products obtained from wild plants and animals.
(g) Forest fires should be prevented.

Page No 110:

Answer:

The IUCN has an important role in categorising species. It has identified all the species in the following categories.

(a) Endangered species, which are in danger of extinction
(b) Vulnerable species, which face the danger of falling under the category of endangered species
(c) Rare species, which are specific to certain geographical areas and may fall under the vulnerable or endangered category
All these three categories of species together are called threatened species.

Page No 110:

Answer:

Endangered species  Endemic species
These species are not confined to a specific geographical area. These species are confined to a specific geographical area.
These species face the danger of becoming extinct in the near future.  They may or may not face the danger of becoming extinct at present.
Example: The Indian rhino is an endangered species whose population is very small. If it is not protected, it may become extinct. Example: The Nilgiri langur is an endemic species confined to the Nilgiri Hills.

Answer:

Birds and animals sometimes travel long distances from their habitat to overcome unfavourable conditions during some seasons. This movement might also be a part of the life cycle of some birds. The movement of a large number of birds and animals over long distances is called migration. For example, the Siberian crane migrates to India in large numbers during winter to escape harsh, cold winter conditions. The eel lives in fresh water but goes to the sea for laying eggs, and when the young ones hatch from the eggs, they return to rivers.
