Hydro Electric Dams Are An Environmental Disaster

1157 words - 5 pages

Almost, everything runs with electricity, dams are what produce most of this electricity. Hydro-electric dams are very essential nowadays as they massively supply electricity to the world. Some people believe that hydro-electric dams are not environmentally friendly, hydro-electricity is produced by water. Canada is ranked second in the production of hydro-electricity (Hydroelectricity Energy), the hydro-electric dams produce 59% of Canada's energy (Trading Economies).There are over 933 large hydro-electricity dams in Canada. Quebec consists of most of these dams where they have around 333 large hydro-electric dams (Water-How we use it). A hydro-electric dam pulls water from rivers close by decreasing water levels which increases the risk of fish extinction, causes direct floods due to pre-existing watersheds and a vast swath of land must be used which results in displacement of local people. Therefore, hydro-electric dams are not an environmentally responsible form of generating energy.
To begin, hydro-electric dams are not an environmentally friendly form of energy because it will decrease water surrounding water levels, which results in an increased fish extinction rate. The Yunnan dam in China caused deaths of over 1,770 tons of fish due to the low water levels (Tao,1). The Yunnan Dam pulls water from rivers close by it in order to produce efficient energy which decreases the water levels, resulting in extinction of fish (American Rivers). Therefore, many endangered fish species. The decreasing water levels around the dams will result in fish being extinct. The Three Gorges Dam in Hubei is endangering twenty-five out of the 600 fish species in China (Scientific American). The Three Gorges dam needs massive amounts of water to generate electricity demands. When the dam is not receiving enough water it will then start to pull from rivers around it which decreases water levels and makes it harder for the fish to survive (Scientific American). As a result, building dams will decrease water levels from surrounding rivers which results in higher extinction rates for fishes. Canada relies highly on hydroelectricity as it is there major electricity producer, they should not rely on these dams because they will start increasing extinction rate for fish species. Most of Canada's fish population may become extinct if they continue the use of these dams non-environmental dams.
Furthermore, hydro-electric dams are not an environmentally responsible source of generating energy because when they are built, a vast swath of land must be used, resulting in displacement of local people. The amount of land needed to build a dam is large which will displace many people. When the Three Gorges Dam project was approved, it forced over 1.4 million people to relocate (Business Insider). The Three Gorges Dam needed to be a large dam because of the growing energy needs in China. This would require vast areas of land and so the amount of people relocating increased...

Environmental Impact of Rservoirs

For dams to generate electricity or supply water, it comes at an expense towards the environment. When these reservoirs are constructed, it causes a barrier in the river which affects the ecosystem. Governments create these dams for economic development without seeing the environmental impacts that are occurring. If no solution is agreed to solve
