Question

Which of the following do not indicate biodiversity depletion?

• A. Large-scale depletion of ecosystems.
• B. Overexploitation of the natural resources.
• C. Excessive use of chemicals in agricultural fields.
• D. Organisms being protected in their natural habitats.

Answer 1

The correct option is D Organisms being protected in their natural habitats.

Reduction or loss of plant and animal species is called biodiversity depletion. Depletion of biodiversity can take place due to the following reasons:
$\bullet$ Activities such as deforestation, hunting, etc. when practiced on a large scale, leads to the depletion in biodiversity.
$\bullet$ Cutting down of trees for raw materials like timber and wood, over usage of fossil fuels such as coal and petroleum, etc. leads to the overexploitation of natural resources.
$\bullet$ Excessive use of chemicals in agricultural fields leads to soil infertility. This also affects the micro-organisms present in the soil.
However, when organisms are protected in their natural habitat it will not lead to the depletion of the biodiversity.
