Question

Which of these statements best describes the impact of ocean thermal power and current power on the environment?

Current power may decrease the fish population.

Current power may decrease the gravitational pull of the moon.

Ocean thermal power may increase the fish population.

Ocean thermal power may increase the gravitational pull of the moon.

Answer 1

Neither will affect the gravitational pull... their impact on fish population is what you should investigate. I find it hard to believe either would *increase* fish population but I'm not sure.
