Which of the following best describes the long-term impact of using a nonrenewable energy source?

Hello. This question is incomplete. The complete question is:

"Which of the following best describes the long-term impact of using a nonrenewable energy source?

A: Geothermal energy can disrupt the water table and harm water supplies.  B: Nuclear power damages the atmosphere by producing air pollution.  C: Burning biomass to produce energy releases greenhouse gases.  D: Coal mining can pollute water supplies and kill fish and aquatic plants."

D: Coal mining can pollute water supplies and kill fish and aquatic plants.

Explanation:

The use of non-renewable energy has proven to be a strong pollutant of ecosystems and biomes. Coal mining is an example of how the use of non-renewable energy degrades nature.

The environmental impacts of mining are diverse and varying in scale: from specific local problems to major biological, geomorphological, water and atmospheric changes. Therefore, knowing these problems and minimizing their effects is of great necessity to ensure the preservation of natural environments.

Coal mining can pollute the water supply and kill fish and aquatic plants. Not to mention the degradation of soil and vegetation that this activity promotes.

9.9 years

a = p(1 + rt) . . account balance after time t at rate r starting with principal p

3000 = 2500(1 + 0.0202t) . . filling in the given numbers

1.2 = 1 + 0.0202t . . divide by 2500

0.2 = 0.0202t . . . subtract 1

0.2/0.0202 = t ≈ 9.901

it will take about 9.9 years for the account balance to reach $3000.
