How does a hydroelectric power plant affect the environment?

• It releases harmful wastes from the turbine into the river.
• It decreases the water level upstream from the power plant.
• It restricts aquatic animals of the region from reaching parts of the river.
• It releases carbon dioxide in the air during the generation of electricity.
