surface mining for uranium pumping oil from under water harvesting wood by selective cutting collecting natural gas from old oil wells
I gave my students this multiple choice question: Which of these methods of energy resource acquisition has the least effect on the lithosphere?

Only one answer is correct among these 4 choices:
- surface mining for uranium
- pumping oil from under water
- harvesting wood by selective cutting
- collecting natural gas from old oil wells

Could you tell me which one is correct?

harvesting wood by selective cutting
