fishing in a lake using water to produce electricity planting native plants along a lakeshore directing runoff from cropland into a lake
I gave my students this multiple choice question: Students are learning about the natural resources in Maryland. One group of students researches information about renewable natural resources in the state. The other group researches information about nonrenewable natural resources in the state. The resources the students investigate include plants, animals, soil, minerals, water, coal, and oil. Which of the following human activities negatively affects a natural resource?

Only one answer is correct among these 4 choices:
- fishing in a lake
- using water to produce electricity
- planting native plants along a lakeshore
- directing runoff from cropland into a lake

Could you tell me which one is correct?
