What is the central idea best described by a paragraph about recycling's impact on the environment?

• A. Recycling helps conserve resources and protect the environment.
• B. Recycling wastes time.
• C. Recycling damages ecosystems.
• D. Recycling is optional.

Answer: (A)

Recycling has a positive impact on the environment by helping conserve resources and protect the environment. The main idea here is that recycling reduces the need to extract new raw materials, which saves natural resources like minerals and trees and often uses less energy. It also cuts down on the amount of waste that goes to landfills, which lowers pollution and can reduce greenhouse gas emissions. Because this statement captures the overall message that recycling benefits the environment, it’s the best description of the paragraph’s point. The other options describe ideas that don’t fit the paragraph’s message, such as recycling wasting time, damaging ecosystems, or being optional.
