On the positive side the dam is a renewable energy source but environmentally speaking it has done more damage than good. The construction of the TGD has had a huge negative impact on the environment all along the river. The controlled water flow has caused a decrease in water quality and changed the niche of many wild life species. Fish can’t simply swim up and downstream freely anymore which can affect their diet and matting patterns. The water behind the reservoir has destabilized some of the steep hills on the edges of the water causing landslides that can be very dangerous.
This results in a lower velocity and less discharge of the river Yangtze which therefore leads to a reduction in flooding. The dam is an appropriate strategy for China in a sense of cost and maintenance. As China is a fast growing MEDC and an ever expanding economy the strategy of a dam can be supported here because there is enough money to pay for the cost and the high maintenance of the dam which ensures that the dam can stop the rick of flooding along the Yangtze River. If you were to put this strategy in an LEDC such as Bangladesh for example, because Bangladesh’s economy is not very good they would not be able to cover cost and maintenance which as a result the dam could not efficiently provide the objective for what it has been put there to do.
Three Gorges Dam The Three Gorges Dam is built on the Yangtze River in Central China. The dam is the largest HEP in the world and is massive in scale. The dam 2,335m wide, 101 metres high and 115m thick. It has 34 generator with an electricity capacity of 22,500MW. The reservoir behind the dam is 660km long and has a surface area of 1,045km2.
The Three Gorges Dam is a model for disaster, yet Chinese companies are replicating the model. Huge hydropower cascades have been proposed and are being constructed in some of China’s most pristine and culturally diverse river basins. Around the world, large dams are causing social and environmental devastation while better alternatives are being ignored. It is the world’s biggest hydro project and the problems that come along with it are not unA third of China’s 1.3 billion people live in and around the Yangtze River basin. For centuries,
The Three Gorges Dam INTRODUCTION The Three Gorges Dam is the world’s largest hydropower project and most notorious dam. The massive project sets records for number of people displaced (more than 1.2 million), number of cities and towns flooded (13 cities, 140 towns, 1,350 villages), and length of reservoir (more than 600 kilometres). The project has been plagued by corruption, spiralling costs, environmental impacts, human rights violations and resettlement difficulties. Flood Control: Since the beginning of the Han Dynasty 2,300 years ago, there have been 214 major floods recorded, averaging 1 flood every ten years. Within this past century, there have been five major floods that were recorded to have claimed hundreds of millions of lives, millions of acres of farmland, destroyed thousands of homes, and billions of dollars of damage.
Inside the hall were engines and generators representing not only the best and newest engineering of America but also of England, Germany, and France (Buers 14). The Palace of Machinery held the power plant that created the 56,000 horsepower needed to sustain the amount of energy used for the Fair. It generated electricity for the lights; as well as ran the massive pumps that fed water to the grounds lagoons and picturesque Cascades. At this point in time only two other power plants in the world had a greater horsepower than the engines featured here. The Allis Chalmers vertical and horizontal refrigerating engine was also here, capable of generating 5,000 horsepower, along with the Curtis Steam Turbine from General Electric Company, which could produce 8,000 horsepower (Corbett 3-5).
It is easy to see why this rainforest is so marveled upon. The Amazon rainforest is the most species-rich rainforest in the world, and makes up more than half of the remaining rainforests on the planet. However, with the increasing need for cattle pasture, farming space, and precious wood, deforestation has been devastating the Amazon. Deforestation is the removal of trees, where the left over land is changed for non-forest use. Although clearing trees in the Amazon provides economic benefits, the environmental effects are serious dangers to it’s ecosystem as well as species within it.
There were also old Egyptian structures that had to be carefully moved to avoid destruction from the new path of the river. These relocations sparked controversy and resistance from the Egyptian people due to the old structures being a large part of the tourist attraction in Egypt. Another big problem the Dam caused was with the soil around the river. Normally the soil was very good for farming, even with the annual floods, but the construction of the Dam caused the nutrients in the water to stop flowing to the soil. The result was poor farmland and in turn, the poverty of the farmers wasn’t completely solved.
In this paper, I will write about the two major cause of AIR and WATER Pollution in China, chemical pollutants in the air and industrial and agricultural waste dumped into the groundwater. Although there are other pollution problems, polluted air and water are the largest, and have become the biggest threats to Chinese people’s health. Air pollution happens when there is the presence of abnormal concentration and abnormal constituents in the air. We know that fresh air is needed for a healthy life. That is why people in China go out for morning walks so that they can breathe as much fresh air as possible because most of people feel that the morning air is better and so it is common for Chinese.
The Project The Three Gorges Dam stretches more than two kilometers across one of the greatest rivers in the world, the Yangtze. The dam was built in a stretch of the Yangtze known as Three Gorges because of the canyons formed by immense limestone cliffs. These gorges— the Xiling, Wu, and Qutang—offer some of the most scenic landscape anywhere in the world and have long been a destination spot for tourists from around the world. In recent years, tourism has boomed as people have rushed to see some of the sights to be destroyed by the dam and reservoir (China View 2008). The beauty of the region has inspired Chinese poets and artists for centuries including much of the work of Li Bai (701–762 AD), considered by many Chinese to be the world’s greatest poet (Fearnside 1988).
