Since the choices are not listed, it would be difficult to identify what is really the answer. The best I could do is to list some of the environmental consequences of the use of nuclear energy. This type of energy is said to have the lowest impact on the environment since it does not have eany emission that would cause air pollution, its waste is isolated from the environment and would only need a small amount of area of land. Although it has the lowest impact, it would still have an effect on the environment. One would be the amount of radiation that will be emitted when a meltdown would happen. This would affect not only the environment but all of the living things including humans. Also, it could cause eutrophication from the wastes.
