What is the benefit of reducing single-use plastic?

Correct answer: Plastic pollution is reduced

The governing concept is pollution prevention through reducing unnecessary waste. Single-use plastic items are often used briefly but can remain in the environment for a very long time. If their consumption is reduced, fewer bags, wrappers, cups, and containers enter streets, drains, rivers, soil, and landfills. This lowers litter and the risk of harm to animals, while also reducing the need to manufacture and dispose of additional plastic. Therefore option A is correct: plastic pollution is reduced. Cutting single-use plastic does not increase coal production, cause rainfall to decrease, or make rivers dry up. Those options have no direct logical connection to the practice.
