Question

Which type of pollution is caused by overgrazing leading to soil nutrient loss?

• A. Positive pollution
• B. Qualitative pollution
• C. Negative pollution
• D. Anthropogenic pollution

Answer 1

Answer:

C. Negative pollution

• Correct Answer: Option C - Negative pollution

• The refers to negative pollution, also known as soil degradation or land degradation.

• Overgrazing occurs when too many animals graze on a piece of land for extended periods without allowing the vegetation adequate time to recover.

• This excessive grazing:

• Removes vegetation cover that would normally protect the soil

• Compacts the soil through trampling, reducing its ability to absorb water

• Depletes organic matter in the soil as plants are consumed faster than they can regenerate

• Leads to erosion as the unprotected soil is exposed to wind and water

• Results in significant loss of soil nutrients as the natural nutrient cycle is disrupted

• Negative pollution refers to the depletion or removal of essential components from the environment, as opposed to positive pollution which involves the addition of harmful substances. In this case, overgrazing causes negative pollution by removing nutrients from the soil system.

• Positive pollution: Addition of harmful substances to the environment

• Qualitative pollution: Not a standard classification of pollution

• Anthropogenic pollution: Refers to pollution caused by human activities in general
