Question

What are the major causes of environmental pollution?
A. Human population explosion
B. Rapid industrialisation
C. Deforestation
D. All of these

Answer 1

Hint: Environmental pollution occurs when there is an unfavourable alteration in the environment that has a negative impact on plants and animals. The term "pollutant" refers to a material that contributes to pollution. Pollutants can be liquid, solid, or gaseous in nature. When the concentration of a substance exceeds the natural abundance, it is classified as a pollutant. This increase in concentration might be caused by human actions or natural phenomena. There are contaminants that can be degraded and broken down quickly by natural mechanisms, comparable to how vegetables decompose.

Complete answer:
Option A: The primary cause of environmental degradation is human population growth, which is connected to other issues. Uncontrolled human population growth resulted in excessive resource use and natural resource depletion.
So, option A is not correct.
Option B: Industrialization is taking place in order to meet demands that lead to air, land, and water pollution which in turn is causing environmental pollution.
So, option B is not correct.
Option C: Agricultural land is disappearing, and forests are being cut down for residential and industrial purposes, resulting in deforestation and soil erosion and degradation. In many ways, over-farming and resource misuse are rapidly harming the ecology.
So, option C is not correct.
Option D: The human population increase is the primary source of environmental degradation, and it is linked to other factors. Excessive resource use and natural resource depletion stemmed from uncontrolled human population increase. Industrialization is being carried out in order to meet demands that contribute to contamination of the air, land, and water. Agricultural areas are dwindling, and forests are being cut down for residential and industrial purposes, resulting in deforestation, which causes soil erosion and land degradation. Over-farming and resource overuse are fast degrading the ecosystem in many aspects.
So, option D is correct.

So, the correct answer is “Option D”.

Note:
“Pollution is the introduction of substances (or energy) into the environment that create negative alterations in living things.”
Chemical pollutants, such as particles, are not always the source of pollution (like smoke and dust). Sound, heat, and light are all forms of energy that can pollute the environment. Pollutants are the substances that pollute the environment.
