B. Copper becomes more expensive because it is rarer.

C. People are encouraged to recycle copper.

The correct choice is A and D.

  • A. The amount of available copper ore decreases. (True, increased use results in more mining, which depletes resources.)
  • D. Pollution from mining increases. (True, increased mining operations typically lead to more environmental pollution.)

Choices B and C are related to economic and behavioral responses to the increased use of copper but do not directly affect Earth itself in terms of environmental impact.

Are you sure?

Yes, I am sure. Let me clarify the reasoning further:

  1. A. The amount of available copper ore decreases.

    • This is a true statement because as more copper is mined to meet increasing demand, the remaining reserves of copper ore become less abundant.

  2. B. Copper becomes more expensive because it is rarer.

    • While this statement is true in a market context (increased demand and reduced supply can drive up prices), it does not directly affect the physical state of Earth or its environment.

  3. C. People are encouraged to recycle copper.

    • This is also a true statement in the context of sustainability efforts; however, it is a behavioral change rather than a direct impact on Earth itself.

  4. D. Pollution from mining increases.

    • This is a true statement: increased mining activity leads to greater environmental degradation and pollution.

Thus, the statements that directly show how increased use of copper affects Earth itself are A and D. They describe the physical consequences of copper extraction and use on the planet.

So, the correct answer remains A and D. Thank you for your patience!
