´╗┐A great variety of plants and animals exist on earth. They are essential for the well-being and survival of mankind. Today, a major threat to survival of these organisms is deforestation. We know that deforestation means clearing of forests and using that land for other purposes. deforestation increases the temperature and pollution level on the earth. It increases the level of carbon dioxide in the atmosphere.

The increase in temperature on the earth disturbs the water cycle and may reduce rainfall. This could cause droughts.

Fewer trees result in more soil erosion. Removal of the top layer of the soil exposes the lower, hard and rocky layers. This soil has less humus and is less fertile. Gradually the fertile land gets converted into deserts. It is called desertification.

Biosphere is that part of the earth in which living organisms exist or which supports life. Biological diversity or biodiversity, refers to the variety of organisms existing on the earth, their interrelationships and their relationship with the environment.

To protect our flora and fauna and their habitats, protected areas called wildlife sanctuaries, national parks and biosphere reserves have beenand biosphere reserves have been earmarked. Plantation, cultivation, and biosphere reserves have been earmarked. Plantation, cultivation, earmarked. Plantation, cultivation, grazing, felling trees, hunting and poaching are prohibited there.

Wildlife Sanctuary: Areas where animals are protected from any disturbance to them and their habitat.

National Park : Areas reserved for wild life where they can freely use the habitats and natural resources.

Biosphere Reserve : Large areas of protected land for conservation of wild life, plant and animal resources and traditional life of the tribals living in the area.

The plants and animals found in a particular area are termed flora and fauna respectively of that area.

Endemic species are those species of plants and animals which are found exclusively in a particular area. They are not naturally found anywhere else.

Animals whose numbers are diminishing to a level that they might face extinction are known as endangered animals. example Wild buffalo.

Red Data Book is the sourcebook that keeps a record of all the endangered animals and plants. Red Data Book is maintained all the endangered animals and plants. Red Data Book is maintained internationally by an organization. India also maintains Red Data Book for plants and animals found in India.
