Question

what is one way to make earth’s coal supply last longer?

a. install scrubbers in power plants.

b. capture and store carbon.

c. replant diminishing forests.

d. build and use wind power plants.

Explanation:

To make Earth's coal supply last longer, we need to reduce the demand for coal. Wind power plants are a renewable energy source. By building and using them, we can rely less on coal for energy, thus extending the coal supply. Option A (scrubbers) reduces pollution from coal use but doesn't extend the supply. Option B (carbon capture) also deals with emissions, not supply extension. Option C (replanting forests) is related to ecosystems and carbon sequestration, not directly to coal supply duration.

Answer:

D. Build and use wind power plants.
