Globalization Effects on Jamaica and Thailand Essay

3.5 million miles of water run throughout the United States; and since the country’s conception, over 80,000 dams have impounded 600,000 miles of these waters [1]. Dams were originally constructed to provide water to towns and establishes energy sources for mills and later hydroelectric plants. Because these dams were constructed decades ago, they’re reaching a critical point of obsoleteness where they cause more harm than good. Dam removal is increasingly popular across the country to address the ecological problems including habitat loss and sedimentation, despite potential for downstream harm, removing dams is more environmentally and economically cost effective than upgrading them. The Marmot, Glines Canyon, and Elwha river dam removal projects each highlight different challenges of dam removal, but overall

Dams. They’re such a controversial topic in today’s society. Some people think they’re doing good for our world, while others believe that they’re negatively impacting the atmosphere in which we live. They don’t take into consideration all the harms they’re doing for creatures such as fish. Animals aren’t the only things they’re affecting. These dams are playing a huge role in transportation for shipping goods. It’s not a good thing at all. In fact, people’s recreational activities are also being limited due to the dams.

-Growth in beaver populations meant more dams which had multiple beneficial effects on streams and rivers. Dams slow seasonal water runoff and help to maintain a healthy water supply. The pools created by dams also created good habitats for fish. More abundance of willows made great songbird habitat.

In 1992, The Elwha River Ecosystem and Fisheries Restoration Act of 1992 authorized the US Federal Government to acquire the hydroelectric power projects of Elwha Dam and Glines Canyon Dam, where are located on the Washington State for demolition for habitat restoration and decommissioning. The dam removals began in 2011 and finished in 2014. I wondering that why government decided to remove the dam and what happens in Elwha River after dam removal. In this paper, I write about the following topics: main purpose of the Elwha and Gliens Canyon dam, effects to the Elwha River as well as ecosystem after constructing dam, reasons of the dam removal, process of the dam removal, and effects after dam removal.

In addition, farmland has been destroyed because of the floods and the decrease in delta sediment. The dam has reduced downstream nutrients and sediment flow. And has seriously impacted neighboring river and seacoast ecosystems.

There should never have been an increase in the size of the dam if it was going to cause such a great impact on surrounding environments. The location where the water was released is now dead and still somewhat submerged under water. The organism have not returned, new organisms may have come but in terms of an ecological factor should not be there. Another option would have been to build the dam up instead of out, or even create a new damn in an environment that wouldn’t have been as effected, and they could have either joined the dams, or separated the flow from the Hinze dam, and the new dam could provide water to those areas not receiving water from the Hinze dam anymore. Also close by to the Hinze Dam is the Nerang Dam, so why not expand the Nerang Dam. This would have given the increase in water that the Hinze dam needed, without the that the Hinze Dam has left on the environment. I don’t if the experts who made these decisions new exactly where the water from the Hinze dam would go when it was released, and they probably thought we will worry about it when it comes to it. Or they may have known, but that may have been the area that would have been affected least, so that’s why it was chosen to flow there. So far however nothing has been done to repair the damaged area, and it has almost become a new type of environment because of

Studies before the dam removal have shown that 83% of the Olympic National Park has been untouched and is still considered a pristine wildlife habitat which is good news. This means that if the lower end from the dams and below can restored then the Elwha River ecosystem theoretically will recover as well. Of the lower 5 miles that was left available for fish spawning, not very much of it was usable. The dams cause a baseline shift in the lower river by changing the composition of the river bed from fine sediment to larger stones and boulders which is not prime spawning habitat for fish. The negative effects of the dams, both indirect and direct,

The fragility of river biome ecosystems are increasing more and more with each passing year. Development of man-made, hydraulic obstructions and pollution are two of the biggest factors putting the Missouri River at risk. Less than 70% of the planet’s longest 177 rivers are without man-made structures, such as dams. The number will only continue to increase as global populations grow and untapped rivers are targeted. Structures built on rivers negatively affect plants, animals, and especially humans, as the majority of water used by people comes from rivers. The effects of interfering with the natural flow of rivers can already be seen in the straining of the Colorado, Indus, and Yellow rivers, as they have begun to dry before reaching the sea. It is only time before the Mississippi River, which is a continuation of the Missouri River, is affected as such. The aforementioned demonstrates the expanding environmental harms rivers are facing. Backing this up, scientists have shown that disrupting a river’s natural flow patterns incredibly affects its wellbeing. For

The United States has led the world in dam building for the past 100 years. The dams are used for a variety of purposes, including hydropower, irrigation, flood control, and water storage. Even though dams can be a benefit to society, they can also cause a lot for harm to the rivers. Dams degraded river ecosystems, depleted fisheries, and diminished the recreational use of nearly all of the nation’s rivers. Many of the dams are unsafe, old or no longer serve their intended purposes.

For example, the flight that Virgin Atlantic provides to Asian countries will contribute to the nation tourism aspects. Foreign tourist from the Europe and all perhaps from all over the world will come to Asian countries. This will boom the tourism industry in the particular country. This will develop the infrastructure of the country itself (Tucker, 2010). In terms of employment, especially that rely on tourism industry, more and more labour will be needed. Hence, the requirement for workers will increase. Job seekers around the world will come to that country to seek for job. In fact, the local people themselves will need to compete with foreign workers to get the job. Hotels for example, will be built and increased from time to time.

The dams being built took away many amazing and flourishing fisheries and Indian grounds. Salmon and other wild fish struggling to get back upstream to their spawning grounds as fish ladders in the dams either were too hard to navigate or simply did not exist. For salmon it is lack of access “end of story”

Many fish cannot pass through the dam. This impacts their breeding and migration. While many will argue that some fish can make it through, there are still dangers for the fish on the other side. After water enters the dam, oxygen is sucked out of it. This little bit of oxygen is essential for fish to survive in the water, and without it, they suffocate and die.

The Nile River is in jeopardy because of a dam. In 1843, a dam was about to be built across the Nile. The dam was 12 miles down to the city of Cairo. The dam was what everyone was talking about for a while, although it was completed in the year 1861. After the dam was built, it was then extended and improved, it was marked as the beginning of the modern irrigation in the Nile Valley. In the year 1901, the Zifta Barrage was added to the system. Only a year later, in 1902, the Asyut Barrage was more than 200 miles upstream from Cairo. Then there was the first dam at Aswan that was built between 1899 and 1902. After years and years, the dam has been enlarged. In 1929 and 1934, the water level rose, but the dam's capacity increased. The Aswan Dam was located to 600 miles upstream from Cairo and 4 miles upstream towards the real Aswan dam that was created. What was really the dam job? It was to control the Nile water, so the crops could get provided with water. All of this hard work started in 1959 and then completed in

The establishment of new financial institutions helped the “public works projects” to rise. One of the examples of these projects was the Tennessee River Valley in 1933. The government constructed 20 dams and coal-fired power plants with a purpose to provide electricity to poor areas. Although the project provided many benefits, it also created a quite few ecological concerns. Construction of dams flooded to many areas. Mining of coal caused pollution and erosion. The same situation was evident across the globe. Thailand has built 26 irrigation and hydroelectric projects since 1957. Most of them were financed by the World Bank. The country started

Loss of Biodiversity: With the increased urbanization and industrialisation, there have been several proposals of hydrological dams to support the demanding economic growth. As per China Ecological Footprint Report, 2012, the biodiversity of China is under massive threat due to the construction of four dams.
