Hey mate♥️
Here is ur answer
Environmental pollution:
Environmental pollution is defined as “the contamination of the physical and biological components of the earth /atmosphere system to such an extent that normal environmental processes are adversely affected.
Biodegradable pollutants:
Those pollutants which can be broken down into simpler, harmless, substances in nature in due course of time (by the action of micro-organisms like certain bacteria) are called biodegradable pollutants.
Non- biodegradable pollutants:
A pollutant that is not broken down by natural processes. Some nondegradable pollutants, like the heavy metals , create problems because they are toxic and persistent in the environment . Others, like synthetic plastics , are a problem because of their sheer volume.
Three ways to maintain a balance between environment and development to survive are:
(i) Forest resources should be used in an environmentally and developmentally sound manner.
(ii) Instead of using non-renewable natural resources use of renewable natural resources should be preferred.
(iii) Waste water generated by industries should be recycled.
