Nowadays, people seek to efficiently use all natural resources to produce value. Hydroelectric Power is seemingly a wonderful way to achieve the goal of reducing cost as well as producing more power. However, from the passage named “The Hidden Cost Of Hydroelectric Power”, it can be seen that the significant effects on the climate and animal species within the area building enormous dam are not eligible.

The substantial consequences include damaging river ecosystem, destroying villages nearby, and  flooding agriculture lands.  To begin with, the dams dramatically rises the water level and interrupts the flow of the river. As a result, the climate will change due to the larger amount of water, leading to the temperature and humidity vary, so the animal species live around need to struggle the changes for them. Besides, the interruption of water caused the fish species need to migrate and reproduce lost its living habit, and even become extinct. Thirdly, some artificial heritage, like houses with long history, or some momentary buildings near the river would be flooded. Though some of it can be moved, it costs a huge amount of money of the government. For instance, with the construction of Three Gorges Dam in China, over three thousands of residences’ home were destroyed.

In conclusion, hydroelectricity is an efficient resource of producing power, but the latent costs are considerable.
