Expert Answer
Materials which can not get destroyed easily and naturally by bacterial decomposition circumstances are non-biodegradable.
The articles made of plastics are non-biodegradable.
This causes a great problem in the disposal of plastic wastes.
The burning of plastic wastes gives out harmful gases into the atmosphere, causing air pollution.
Animals eat the plastic, which can cholk them and can even die.
Thus, plastic is non-biodegradable. It get accumulated in environment and in water bodies. Animal and marine fishes eat it and can die due to chocking. Burning of plastics release poisonous gases. Hence, plastic or polythene bags are dangerous.
