Question

Number of wild life is continuously decreasing. What is the main reason of this :-

• A. predation
• B. Cutting down of forest
• C. Destruction of habitat
• D. Hunting.

Answer 1

The Correct Option is C

The question addresses the decline in wildlife populations, prompting us to identify the primary cause. The correct answer is destruction of habitat.

Let's analyze why this is the most suitable choice:

1. Predation: This is a natural process where organisms hunt other organisms. Although predation does affect population dynamics, it is a natural part of the ecosystem balance, rather than a direct factor caused by human activities.
2. Cutting down of forest: While deforestation leads to the loss of forested areas and is a significant environmental issue, it is often considered part of habitat destruction. Trees are cut down for agriculture, urbanization, and industrial purposes, directly impacting wildlife habitats.
3. Destruction of habitat (Correct Answer): Habitat destruction is the process by which natural habitats become unable to support the species present due to human activities such as deforestation, urban development, and pollution. This is the leading cause of species extinction worldwide as it eradicates the living conditions necessary for wildlife survival.
4. Hunting: This involves killing animals for sport, food, or trade. While hunting does contribute to decreasing wildlife numbers, it is not as pervasive a cause as habitat destruction, which affects the entire ecosystem.

By understanding these explanations, it's clear that the destruction of habitat encompasses not only the removal of flora but also the degradation of the conditions necessary for animal life, making it the primary reason for the decline in wildlife populations.
