Answer 1

The correct response that shows ways the increased use of copper affects Earth itself is A and D.

• A: The amount of available copper ore decreases as more copper is mined.
• D: Pollution from mining increases as more mining activity occurs to meet the demand for copper.

While B (copper becomes more expensive) and C (people are encouraged to recycle copper) are true statements, they are more about economic and social impacts rather than direct effects on the Earth itself. Therefore, the best answer is A and D.
