Question

how non- biodegrdable waste pose a threat to the environment?

Answer 1

↵Non- Biodegradable substances are those substances that do not breakdown into simpler forms. Micro-organisms do not have enzymes to breakdown plastic, glass, detergents etc.So such substances enter the food chain and harm the organism in the higher trophic levels. Non-biodegradable substances like radioactive wastes, lead, mercury etc. affect the health of all living organisms.They would also become an burden on the environment because they would accumulate. They also produce harmful polluting gases if they are burnt
