Three Gorges Dam


The three gorges dam project brings the humanity to the greatest hydropower construction. Although, the project is unbalanced between providing energy for the country and causes human/environment interaction. First of all, the dam provides much electricity for China. The gorges dam provides 18,2 GW, as much electricity as a country like Vietnam uses. Coal is the main resource that China used to burn and take energy from. Burning fossil fuels negatively affects to the atmosphere of the Earth. Now, instead, people take advantage of the water flow to turn the turbines and generate electricity. Generating energy by hydroelectricity will be a friendlier way to exploit for energy. At the same time, building three gorges dam is also a human/environment interaction, and because the project is the world largest project in hydropower, meaning it affects really much to the environment. The species whose habitats are in the river, such as fish could die because of trash stuck inside the water in the upper part of the river. Human is also a part of this bad influence. Pollution in the upper part of the river may spread diseases. People may have to move because of the reservoir started to expand. As what people can observe, to meet the demand of electricity, the cost to pay is human’s own environment.
