Non-biodegradable pollutants are created by:

Non-biodegradable pollutants are degraded either very slowly or not degraded at all. These are mainly created by various human activities like excessive use of plastics, industrialization, building of houses, use of leaded petrol in vehicles, etc.

The nature creates biodegradable waste like dry leaves, dead plants and animals, dung, etc.

The excessive use of resources is also done by humans like using excessive amount of petrol but the pollutants like carbon, released by excessive use of resources are biodegradable.

The natural disaster causes destruction of resources, not creation of non-biodegradable pollutants.
