It is usually seen that non-biodegradable substances are manufactured and do not occur naturally, therefore their degradation is also not possible. However, biodegradable items easily decompose in nature by agents like water, soil, sunlight, microorganisms, etc. And it directly or indirectly is profitable to the environment.
