Factors for depletion of flora and fauna

Hunting and poaching of wildlife, overexploitation, environmental pollution are some factors which leads to the depletion of fauna.

What are the 5 causes of animal extinction?

There are five major causes of extinction: habitat loss, an introduced species, pollution, population growth, and overconsumption. Through the activity, students will create a list of reasons why animals can become extinct.

What are the two causes of depletion of wildlife?

Two main causes for the depletion of wildlife. Deforestation- Cutting of trees in forest leads forest reduction and hence wild animals don't have place to live. Pollution- Water pollution and air pollution affects the health of wild animals. It shows bad effect on wildlife.

What are the 6 natural causes of extinction?

Extinction occurs when species are diminished because of environmental forces (habitat fragmentation, global change, natural disaster, overexploitation of species for human use) or because of evolutionary changes in their members (genetic inbreeding, poor reproduction, decline in population numbers).

Is a major cause of wildlife depletion?

Humans cause extinction of a species through overharvesting, pollution, habitat destruction, introduction of invasive species, such as new predators and food competitors, overhunting, and other influences.

What are the major causes of deforestation?

Direct causes of deforestation are agricultural expansion, wood extraction (e.g., logging or wood harvest for domestic fuel or charcoal), and infrastructure expansion such as road building and urbanization.

What are the factors responsible for the depletion of wildlife in India?

Hunting and poaching, habitat destruction, deforestation, over-exploitation, enrichment plantations, environmental pollution and forest fires are factors responsible for the decrease in India's biodiversity.

Which one of the following is the main cause of wildlife depletion?

Major causes of wildlife extinction: Destruction of their natural habitats by environmental pollution, deforestation, soil erosion, overgrazing, increased urbanization, forest fires, and developmental works. Indiscriminate hunting. Introduction of exotic species.

What are the causes and consequences of deforestation Class 8?

Forests are cleared in order to obtain land for urbanisation and industrialisation. Forests are destroyed to clear land for cultivation of crops and cattle grazing. Trees are cut down to be used for firewood.

What is endangered animals Class 8?
