  3. Increases landfill capacity

  4. Minimizes pollution
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Waste reduction reduces the amount of waste that needs to be disposed of in landfills, but it does not increase landfill capacity.

Multiple choice

Which type of waste is typically recycled at a higher rate compared to other types?

  1. Food waste

  2. Plastic waste

  3. Paper waste

  4. Electronic waste
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
