NCERT Solutions For Class 8 Science Chapter 7: Summary
What is Deforestation?
Deforestation means clearing of forests and using that land for other purposes. Trees in the forest are cut for some of the purposes mentioned below:
- a. Procuring land for cultivation
- b. Building houses and factories
- c. Making furniture or using wood as fuel
Consequences of Deforestation
There are certain consequences of deforestation. They are listed as follows:
- – It increases the temperature and pollution level on the Earth
- – It increases the level of carbon dioxide in the atmosphere
- – Groundwater level gets lowered
- – Rainfall and fertility of the soil decreases
- – Chances of occurrence of natural calamities such as floods & droughts increases
- – Cutting down trees will increase the level of carbon dioxide in the atmosphere. This leads to global warming as carbon dioxide traps the heat rays reflected by the earth.
- – Reduces water holding capacity of the soil
- – Makes the soil infertile
What is Desertification?
Deforestation leads to a change in the soil properties. Soil gets eroded because of wind and heavy rain which leads to the loss of the topmost fertile layer of the soil. Removal of the fertile layer exposes the lower, hard, and rocky layer. Gradually, the fertile land gets converted into deserts. This is termed as desertification.
Conservation of Forest and Wildlife
To protect/conserve the flora and fauna and their natural habitat, protected areas called wildlife sanctuaries, national parks and biosphere reserves have been earmarked. Plantation, cultivation, grazing, felling trees, hunting, and poaching are prohibited in these areas.
What is a Biosphere Reserve?
Areas that are meant for the conservation of biodiversity are termed as biosphere reserves.
Biodiversity: It is the variety of plants, animals, and microorganisms found in an area.
What are Flora and Fauna?
Flora: Plants found in a particular area are called flora of that area.
Fauna: Animals found in a particular area are called fauna of that area.
Endemic Species: These are those species of plants and animals which are found exclusively in a particular area. They are not naturally found anywhere else. For example, sal and wild mango tree are endemic flora of the Pachmarhi Biosphere Reserve.
What is Wildlife Sanctuary?
Wildlife sanctuaries are the areas where animals are protected from any disturbance to them and their habitat. Killing or capturing of animals is strictly prohibited and punishable by law in such areas.
National Park: It is an area that preserves the flora, fauna, landscape, and historical objects of an area. There are more than a hundred national parks in India. Satpura National Park is the first Reserve Forest of India.
What is meant by Endangered Animals?
Animals whose numbers are diminishing to a level that they are on the verge of extinction are called endangered animals. Indian elephant, Bengal tiger, Indian lion, Indian rhino, snow leopard, blackbuck are some of the examples of endangered animals of India.
What is Red Data Book?
It is the sourcebook that keeps a record of all the endangered animals and plants. This book is maintained internationally by an organization. India also maintains a Red Data Book for plants and animals found in India.
Migration: It is the phenomenon of the movement of certain species from its own habitat for a particular time period every year for a specific purpose like breeding.
What is meant by Reforestation?
Reforestation is restocking of the destroyed forests by planting new trees.

(c) Migratory birds fly to faraway places because of ____ changes.
A: (a) A place where animals are protected in their natural habitat is called Sanctuary.
(b) Species found only in a particular area is known as endemic.
(c) Migratory birds fly to faraway places because of climatic changes.
1. Species on the verge of extinction.
2. A book carrying information about endangered species.
5. Consequences of deforestation.
1. Species which have vanished.
3. Species found only in a particular habitat.
4. Variety of plants, animals and microorganisms found in an area.
2. Red Data Book
A: If we go on cutting trees, animals will lose their natural habitat as an essential part of their ecosystem is destroyed. This reduces the biodiversity of the affected areas. The temperature of the Earth also increases and gives way to global warming.
A: Removing the top layer of the soil gradually exposes the lower layers of the soil. The lower layers of the soil are hard and rocky in nature and are less fertile.
