Solution:

The correct answer is Because enzymes cannot break down plastics.Concept:Non-biodegradable waste: These substances cannot be decomposed by the decomposers like bacteria and fungi into simpler forms.For example, rubber, plastic, electronic waste, etc.Explanation:Plastic as a boon:It is lightweight and simple to shape.It is inexpensive.Plastic is strong and tough, and durable.It is used to make many daily usable products like buckets, bottles, pencil boxes, pipes, etc.It is corrosion and chemical resistant.It is water-resistant and has adhesive properties.It is a poor conductor of heat and electricity.It is waterproof and airtight and is used to store several food items.Plastic as a curse:It is non-biodegradable.
