Understanding the Impact of Recycling

Which of the following best explains why recycling reduces environmental impact?

A Recycling reduces the need to extract new raw materials, saving energy and reducing pollution.

B Recycling increases the amount of waste sent to landfills, which helps soil quality.

C Recycling uses more energy than producing new materials, increasing carbon emissions.

D Recycling prevents the reuse of materials, forcing industries to innovate.

💡 Hint

Think about how recycling affects raw material extraction and energy use.

Recycling saves energy and reduces pollution by lowering the need to mine or harvest new raw materials.
