The correct answer is D. Generate electricity.
Explanation
A hydroelectric plant is a construction in which, as its name implies, the movement of water is used to generate electricity. These are located in the cause of a river, where they dam the river water, and allow it to follow its current through a complex of tunnels where the water acquires high pressures. Later, the water meets turbines that are moved by the energy that water brings, which generates that this synthetic energy is transformed into electricity. Therefore, the option that best completes the sentence of the question is D. Moving water has been used in hydroelectric plants to generate electricity, but in recent years negative environmental consequences have been known. The environmental damages of hydroelectric plants can be alteration of terrestrial, aquatic ecosystems and their biodiversity, it also generates changes in the river regime, alteration of natural flood cycles.
There are concerns over the inadvertent effects, such as the creation of food that can cause an allergic reaction, GMO that can cause harmful genetic effects, and genes moving from one species to another that is not genetically engineered.
