What is the importance of responsible recycling?

• A. It increases production costs.
• B. It has no environmental impact.
• C. It reduces the need for recycling.
• D. It prevents contamination of soil and water.

Answer: (D)

The key idea is how responsible recycling protects the environment by preventing pollutants from reaching soil and water. When recycling is done properly, materials are sorted and processed so hazardous components don’t end up in landfills or contaminate groundwater and soil through leachate or leakage. This safeguards ecosystems, preserves water quality, and helps reduce the need to extract virgin resources, which further limits environmental harm. The other statements don’t capture this protective impact: some imply costs or no impact, or suggest recycling would be reduced, which isn’t the main importance of responsible recycling.
