2. Describe three benefits and three costs of damming rivers. What particular environmental, health, and social concerns has China’s Three Gorges Dam and its reservoir raised? Benefits include preventing floods, providing drinking water, and facilitating irrigation. Costs of dams include expenses, slowing of river flows, and erosion of tidal marshes. Many people were displaced from their homes, tidal marshes eroded, and many pollutants were trapped in the reservoir.…

The fish that live in the Elwha River are not able to swim upstream and get the food they need and they cannot reproduce so the salmon population just dominates. The Grand Coulee dam was another but its problem was not fish it was flooding and erosion. I would say this is a very controversial topic because the people might believe pro-environment or some might be pro-economy. My point of view on this topic is I do not understand why we say we want to save the environment but we pay millions of dollars to build dam but in which harm the environment by killing of fish. However, I do understand that dam do provide energy. I believe that if we want to have dam for energy we do not need multiple small dams throughout the country instead build a couple of huge one so you are not killing all the fish you are only killing some of them but you are also getting the energy you…
For, it was set to limit the inspection of the industrial waste, since the drains in Guadalajara are mixed; therefore, even the domestic waste is industrial, due to the small workshops and car garages in the inner city and residential neighborhoods (Conant, 2009). Second, the CEAS estimated that the dam project would cost around $41 million U.S. dollars (International Rivers, n.d.). They claimed that the costs will be covered, 60 percent by the state government, and the remaining 40 percent from other federal sources (International Rivers, n.d.). Lastly, in 2001 the Santiago River had been considered an unsuitable source of water, thus, attempting to purify the water possess a threat to the public’s health, since the Santiago River receives wastewater from the industrial corridor of Guadalajara. The effluent, is directly coming from Jalisco’ urbanized regions, causing the El Salto falls and Santiago River to build a thick layer of white foam and a rotten eggs odor that make living in the region intolerable and a major health…
Human beings are the biggest threat to the rainforest ecosystems due to the exploitative nature of our industrial society. As the NIC’s with rainforests in have begun to develop they found the economic value of the rainforests for many international markets as well as internal infrastructure; the resources available are priceless. Logging companies are granted forestry rights, usually cheaply, to harvest timber to sell abroad for furniture, houses and paper. The economic value of this income is invaluable to an industrialising country, as it is usually needed to pay off interest on debts from irresponsible lending in the 1970’s. Electrical power can be created by burning wood, thus large tracts of forests are destroyed to feed a growing demand for power by industry and people. To solve this power problem there have been many hydroelectric dams built to harvest the Amazon rivers power, for example the Tucurui hydroelectric dam built on the Tocantins River used to power the Carajas mine in Brazil.…
1. Why was the building of the dam first proposed in 1919 and by whom?…
This article written by ICMTN Staff refers to the overrun from mining into a river. This river is the source of drinking water and food for many people. Now from this mining spill many people aren’t able to have the plentiful amounts of drinking water. The fish are probably all going to die, since the water is now filled with extremely harmful chemicals. Chemicals that are very harmful to humans, but could be toxic for fish. This is a hard time for the people of this area, and because of that reason, local citizens have declared this event as a natural disaster (ICMTN Staff 1). It’s a disaster to the surrounding wild life, who will die not knowing that the water is contaminated. It’s a disaster for the citizens who can’t fish or drink from this body of water. It’s a disaster for the life that once lived in the…
Nobody can just forget about a loved one after they pass away, but often people never know how to celebrate their life in such a way that they will be remembered forever. Wiz Khalifa does just that with his song, “See you again”, which honors famous actor Paul Walker. Cameron Thomaz, who is widely known as Wiz Khalifa, is a very popular rap artist out of Pittsburgh, Pennsylvania. Although born in Minot, North Dakota, Khalifa started his career while attending high school in Pittsburgh. Khalifa had breakthroughs in his career in the year 2006 and 2007. Through Khalifa’s life, he had many top hits, and big albums that would later help him create one of his biggest hits. In 2013, famous actor Paul Walker passed away who was a huge star in the Fast and Furious movies. He passed away in a car accident off-set while filming of the seventh fast and furious movie was going on. The cast and crew turned to Khalifa and asked…
It is very important to address this issue because the article alludes to the fact that people have fished out of the and more importantly that the lake serves as a water source in some capacity. It is important to remember that contaminated water can affect drinking supply and food supply when used to water crops for consumption. It can also trickle down and affect meat production as the animals ingest the water and food grown using the water. This cycle can be devastating for a community.…
Hoover Dam, also known as Boulder Dam, is a concrete dam built in the Black Canyon of the Colorado River. It was built on the border between the states of Arizona and Nevada and it also crosses the border between two time zones, the Pacific Time Zone and the Mountain Time Zone. When it was completed in 1935, it was the world 's largest electric power producing facility and the world 's largest concrete structure. The dam is located about 30 miles southeast of Las Vegas. It is named after Herbert Hoover, who played a key role in its construction, first as the Secretary of Commerce and then as the President of the United. Construction of the dam started in 1931 and was finished in 1935, which was more than two years ahead of schedule. After many years after construction, Hoover Dam was officially called a national historical landmark in 1985. Behind the dam lies Lake Mead. This is the reservoir created behind the dam and was named after Elwood Mead, who oversaw the construction of the dam.…
Those working in Watershed management know there is little doubt these days that dam construction on our nation’s waterways is having a detrimental effect on rivers and their associated ecosystems. Many of the harmful effects created by dams are not always perceivable to the untrained observer, nor can they be observed on a temporal basis since changes to stream morphology may occur over a span of a few years, to hundreds and even thousands of years. When examining dam construction on healthy and functioning rivers and their ecosystems, what becomes evident is the decline of fisheries and water quality (Mount 236). The damming of natural stream flows degrades fish habitats by increasing…
Also, corporations are under the rule of law, so a corporation can be taxed, brought to court, and face criminal charges. Since, a river cannot be held accountable for natural disasters, and since it does not represent a group of people, Vegter argues that granting legal personhood to a river is drastically different to giving rights to a corporation. In summary, all the authors agree that the environment is a valuable part of human and animal life and should be protected, the only disagreement is on the best course of action for accomplishing this goal. After considering several viewpoints and the connections between them, the next logical step will be to find the most effective course of action to avoid river…
Without the Hoover Dam, many more people would have been jobless during the hard times of the Depression which would have hindered many people needs for inexpensive power and water. While the construction of the Hoover Dam was ongoing, many workers looked to it as a representation of every American’s contribution to a better life. The Hoover Dam caused the once deserted towns in the West to flourish into booming metropolises. The construction of the Hoover Dam helped to excel economic activity and the growing population in the West in spite of environmental problems.…
Two scenes stand out in my mind from my visit to Brazil's Wetland: Forests burning before seed planting and trees as hedgerows. Before the planting season, I could see the leafless remnants of burnt trees still standing. The burning of pristine forests destroys both the habitats and countless species which depend on and thrive in these habitats. The few remaining bare, scarred trees silently convey the cost to our natural resources of pursuing our economic interests. Some forests are preserved by government edict issued in response to international pressure. But most of this preservation occurs alongside major roads not to protect the ecosystem, but to prevent disturbance to ranches and farms along the highways. The clash between economic and environmental concerns that I witnessed in Brazil fascinates me and attracts me to the Environmental Studies Program.…
