Solution
Non-biodegradable pollutants refers to the toxic materials like plastic, DDT, BHC etc. that can not be decomposed naturally by other living organisms. Such harmful substances accumulate in the environment and can cause air, water, and soil pollution. These pollutants are created by humans.
The other three options are incorrect as they do not produce non-biodegradable pollutants.
- Nature - The substances created by nature can be decomposed by living organisms, hence they are biodegradable.
- Excessive Use of Resources - Use of excessive resources do not generate non-biodegradable pollutants. Excessive use of resources leads to their depletion.
- Natural Disasters - Natural disasters do not create pollutants in the environment.
