A computer simulated model of how the finished dam is supposed to look like A computer simulated model of how the finished dam is supposed to look like The three Gorges dam is the worlds largest dam with a total length of half a mile and 600 feet high. The construction of this massive dam took over 21 years starting from planning till the finished construction. The dam was built to stop the floorings that occurred and to cut down the greenhouse emissions of Chinas energy production. With t total production of 100 terawatt per year the dam provides 3% of Chinas total energy consume. But this dam had also been a disaster to the environment and the society. But the construction of the dam also had its negative sides, 1.3million people had to be relocated, many archeological artifacts were buried, the construction caused massive landslides, killed hundreds of fish species and changed the environment around it. But the biggest problem is the effect that it had on the water cycle. The three Gorges dam is one of the most discussed topics when talking about the water cycle.
The biggest problem with this project is the 39 trillion kilograms of water that are store on the side of the dam. This causes million kilos of water to evaporate each day. This causes major rain fall. The large amount of rain is causing minor flooding. These floods do not claim as many lives as the major floods but are still enough to destroy fields and to turn smaller cities into flood plain. The floorings cause the farmers to have large difficulties to find fertile land and so to grow their crops and. This is not a huge issuer since there are millions of farmers in china but it has an effect on the people that live near the dam and their income.
The next problem is Chinas government is deforestation the area around the dam, with the trees cut down the rain, caused by the dam, and cannot be absorbed by the trees anymore. This causes erosion. The forests in the region around the dam have decreased from 20 to 10 percent. The forests have kept the soil in place but now this is no longer possible and the water carries way the soil causing landslides. The Chinese government has now acknowledged this problem but it is too late for them to change the current situation and the only possible method is to relocate the people.

The next problem is the buildup of sediments in by the dam; this causes the water to get large pollution. The missing sediments down the river is also causing a big effect, many of the riverbanks which will normally being reinforced by the sediments are now breaking down due to erosion and due to the lack of trees and plants that would normally keep the sediments in place is now changing the environment. The other side of the river is also a problem, because the buildup of the sediments is a problem to the animals that live near the Yangtze River. Many of the animals need clean water to survive, especially fish. The particles in the water settle in the fishs gills which stops the breathing. The sediments have nowhere to go but to stay in the river; this causes the Yangtze River to turn into a huge sea of mud.
Impact on the mountains:
The three Gorges which are mountains upstream the river, cause massive relief rainfall and the water caused by this rainfall is eroding the mountains slowly and carrying away the base of the mountain. This causes landslides. And the water cant be carried away anymore due to the dam. The land slides are often massive ones which carry 20 thousand to 50 thousand cubic meters of stones and dirt which flow in the river and stay there and so pollute the water. This dirt and rocks would be carried down the river into the ocean. But the dam will not allow this processor. And the dirt will settle on the bottom of the dam and make the water rise.
Another problem involving pollution is the millions of kilos of waste water that are being pumped into the Yangtze River each year. Normally this would be directly flushed into the ocean but now the chemicals and the rest water are now stored at the dam. This has a horrible impact on the people on the upper side of the river because the inhabitants use the water for drinking and for washing their cloths or dishes. The pollution in the water makes the people sick and even kills them. The Chinese government does not take care of this problem and just leaves it to the people in the villages.
The most geographic problem would probably be that the dam is located on a fault line. Minor earthquake are very common in the region where the dam is located. The earthquakes would not bring down the entire dam at once but there have been small cracks. The concrete which 90% of the dam is mad out of could eventually break down the entire dam sending 39 trillion kilos of water down the river killing millions of innocent people. Some of the cracks havent been fixed and more form each day. This might be one of the biggest problems in the construction of the dam.
Influence on the people:

There are many problems with the construction of this dam but the biggest problem with the dam in that for the construction of the dam 1.3 million people had to be relocated. These people were relocated from their houses on the fields which often had been built by their own hands, where they had their fields, cattle and livestock behind because they could not take them with them. They were moved into more-family building which they had never seen before. Often they have many problems with gathering money for their families that often exceeds 20 people. The farmers often many of the farmers havent finished school or ever started it so it is impossible for them to gather money to pay the bills for the house or the food that they need for their family.
Influence on animals:
The construction of the dam didnt claim any human lives, but it will claim millions of lives from the animal side. The Yangtze River is habitat to over 300 fish species belonging to 29 families, there are also other animals that depend on the river, these animals are the big Chinese pander, the Asian tiger or the Yangtze dolphin. These animals are in great danger and I hope that it doesnt take the last one of the animals to die out until the animals are extinct. Many of the birds that travel through this area now have to change their entire rout or even their entire way of live because of the amount of rainfall that course in the region now. The Chinese government knew that these animals would be affected by the constructions of the dam but they still went on with it just to be one of the top nations to win their energy through a cleaner way. The area around the dam was used to be the breeding area for these animals because they had water to drink and food to eat but as soon as the first animal has gone extinct the entire cycle will collapse extinction hundreds of bird, fish and land animal species.
The three gorges in china
The area around the Yangtze river used to be one of the nicest areas in china, it has many wild animals, plants and it was able for tourists to travel from the bottom of the Yangtze river all the way to the top of the river but now due to the three Gorges dam 1.3 million people had to be relocated, massive erosion is occurring, and huge landslides are formed. All of this due to the construction of one dam. The government had thought that they had helped the people by stopping the floorings and with making cleaner energy but now the dam has caused the exact opposite of the planned effect. The three Gorges dam is one of the biggest environmental problems in the world and the Chinese government should consider tearing it down and leaving the surrounding area back to how it had been before the construction of this death wall of stone.
