One of the national parks located near Delhi is the Corbett National Park in Uttarakhand.

The continuous cutting of trees is not justified for any project because it leads to deforestation, desertification, flooding, danger to the lives of wild animals. It also disturbs the balance of nature.

We should conserve biodiversity because each and every organism in nature plays an important role in balancing of natural system.

The habitat of an animal provides it with necessities such as shelter, food and protection. If the habitat of an animal is disturbed, then it will be forced to go to other places in search of food and shelter. As a result, the animal could get killed.

Earth
The various cycles on earth like water, oxygen, carbon dioxide are disturbed due to deforestation. Also, the fertile land of earth is converted into dry land, i.e. desertification occurs by deforestation.

Biosphere is the largest of the three and it may contain a national park or a sanctuary.

No, the Red Data Book keeps record of only those species that are threatened, i.e. either critically endangered, endangered or vulnerable.

Pachmarhi biosphere reserve contains Bori sanctuary and Satpura national park.

A species is a group of same kind of organisms which can interbreed to produce fertile offspring.

Poaching is when an animal is killed illegally.
It usually occurs when an animal possesses something that is considered valuable (e.g. fur or ivory).
Poaching effect on environment The whole ecosystem is affected due to harm caused on animal population. Everything from the animals to the plants and even the people in a specific place are negatively affected.
We need various species of flora and fauna in our environmental ecosystem so that it is balanced and healthy. Our own survival depends on it.
Effect on humans Two serious problems are faced by humans first is spread of food-borne illness, e.g. Ebola and anthrax and second major affect is depletion of important natural resources.

Trees (and other plants) use carbon dioxide gas from the atmosphere for the process of food making called 'photosynthesis'. When a lot of trees are cut down during deforestation, then lesser number of trees will be left. The lesser number of trees will use up less carbon dioxide due to which the amount of carbon dioxide in the atmosphere will increase. In this way, deforestation increases the level of carbon dioxide in the atmosphere.
Carbon dioxide gas traps the sun's heat rays reflected by the earth (causing greenhouse effect). Trapping of heat rays by carbon dioxide increases the temperature of earth's atmosphere. This will lead to global warming. The gradual increase in the overall temperature of earth's atmosphere due to greenhouse effect caused by the increased level of carbon dioxide in the atmosphere is called global warming.
