Deep sea mining is a relatively new mineral retrieval process that takes place on the ocean floor. in mining sites are usually an active and extinct hydrothermal vents at about 1,400 – 3,700 m below the ocean’s surface.The vents create sulfide deposits, which contain valuable metals such as silver, gold,copper, manganese.The deposits are mined using either hydraulic pumps or bucket systems that take ore to the surface to be processed. As with all mining operations, deep sea mining raises questions about potential environmental impact on surrounding areas. Environmental people have argued that seabed mining should not be permitted in most of the world 's oceans because of the potential for damage to deepsea ecosystems and
The Energy East Pipeline is a 4,600 km pipeline that will transport crude oil from Alberta to New Brunswick. The project is in place from TransCanada which is a Canadian company that builds oil pipelines. This essay will explain the benefits and negative effects that can occur if Canada goes through with the installation of the pipeline across Canada. It will also discuss how all three levels of the government influence the subject and who ones to make the final approval is. Currently, the energy east pipeline is still being discussed because there are people who are against the installation of the pipeline and who are fighting to stop this from happenings because they are afraid of what the risks can cause.
The biggest issues facing my community is the Marcellus and Utica shale gas drilling boom. There are many pros and cons involved. I would like to address a few of them here. The pros are mostly economic advantages like, jobs, increased local tax bases and lower consumer prices for natural gas and other products that come out of the wells with it. Some of the cons are increased traffic on roads that are not designed to handle that volume.
Mapping out the ocean floor enabled to Ballard to observe where he should travel to in order for his trip underwater to be safe. He was able to map out the obstacles that could be in his way and disrupt his explorations. With the investigation of unknown species, Ballard was able to observe their lifestyles and extracted information that could be essential to his research besides the abandoned shipwrecks. “On one of his most famous expeditions, Dr. Ballard and a team of scientists traveled to the Galapagos Islands in 1977 and discovered hot springs on the ocean floor called hydrothermal vents” (Education through Exploration). The
The Marcellus Shale It is the largest source of natural gas in the United States, and is located in Appalachian basin which stretches from Tennessee to New York and covers West Virginia, Ohio, and Pennsylvania. The Marcellus Shale has a lot of marine sedimentary rock because of the different sea level changes 400 million years ago that deposited minerals. It contains black shale and lighter shale mixed with limestone .It has many benefits, but it comes with disadvantage disadvantages. For humans to get access to the natural gas they have to drill deep into the ground and create a well which can go from 5,000 to 9,000 feet deep. They use a method of drilling called
All in which are man made influences that affect the ocean greatly. It is predicted that by the year 2050 90% of the coral reefs on earth will be dead or threatened. Not only that but soil erosion, algae growth from fertilizer runoff, increased UV exposure, and damage from fishing and diving are just adding to the problem. However, the
The main way that oil and natural gas reserves are acquired are through the means of Fracking. Also known as hydrofracking, this method utilizes a drill that drills down thousands of feet underground, which is then flushed with millions of gallons of water along with additive chemicals at high pressures to break the rocks sheltering the reserves. This method of attainment is quite risky as it comes with many unfavorable consequences that are quite unbeneficial. Like fossil fuel plants, fracking also releases greenhouse gasses like methane(Potential Health and Environmental Effects of Hydrofracking in the Williston Basin, Montana), which is worse than carbon dioxide and causes air pollution. Alongside that, pollutants like Benzene and Xylene also leak out during the fracking process, which is known to cause serious health conditions and even death in some cases due to the long exposure to the pollutants(Potential Health and
Ilyaas Farah 1711-60 1-31-16 Word count: 501 Sulfide Mining should be rejected Sulfide mining has a bad effect on both the economy and the environment. Sulfide mining is the process of removing copper, nickel, and other metals from sulfide ores. Minnesota 's traditional iron ore mining and sulfide mining are two very different types of mining. Sulfide mining has more environmental risks than Minnesota 's traditional iron ore mining. AMD (Acid Mine Drainage) is created from sulfuric acid.
The reason why I say that is because I was walking through a property that belonged to a business and I saw the workers of these business dumping waste and polluting the area that not only belonged to the property but that was around it as well. Trains were destroying the area by plummeting the soil with its rods which is absolutely terrible because people benefit of soil for many things such as food and clothes which are the basic necessities one needs to live. It’s already bad enough that workers pollute the environment but now also the factories they work in as well which be releasing dirty smoke that harms the air that we breathe as well now. That’s why our natural resources that come in limited amounts are being wasted and damaged by these big companies and
When you look around the horizon of Texas, you can see incredible cities stretching for miles long. You can see the lofty Reunion Tower looking down upon the great city of Dallas or the even great universities still standing from the original foundations such as the University of Texas. These incredible sights we see and attend can all be thanked by the development of Spindletop in 1901, the first oil rig in Texas to gush with oil. Although, many wives of oil workers would have disagreed to this accusation. The would say that oil has destroyed their relationships by taking their men away.
The Board doesn't think enough ocean habitats are safe. They support this with “only 1 percent of marine habitats (are) strictly protected” (par.12). This last statistic allows the reader to realize just how much needs to
Sarah Freeman’s article in The Ethicalist explains the negative effects humans have on the ocean. These negative effects include plastic pollution, global warming, and worst of all, overfishing. Overfishing occurs when a fish species is wild caught faster than it can reproduce. This leads to fewer fish in the ocean, meaning less marine biodiversity (Freeman). After Freeman spends most of her article explaining how the oceans are suffering, she then starts talking about what can be done to prevent a baren sea.
Harmful fishing methods are unnecessarily killing turtles, dolphins, and destroying critical habitats. Global warming is increasing the temperature of the ocean water, reducing the generation of the base of the food web, plankton. The reducing of the plankton generation is causing major marine ecosystem change. Pollution is also a significant environmental issue HAL is facing. More oil reaches the ocean each year, a massive amount of oil has been accidently spilled from ships, which in turn is destroying animal and aquatic plant life.
Which places them in a difficult situation, after all some have no intention in harming or worsening the ecosystem all they want to do is supply for their families. In “Sharing the Catch Conserving the Fish” by David Festa, he describes, “Additionally, overfishing has broad ecosystem impacts. For example, bottom trawling, in which boats drag gear and nets along the seafloor, can damage deepwater corals, sponges, and other features” (Festa, 2). The problem is not so much about what we do, but how we do it. Fishermen are not understanding the negative effects the act of overfishing is creating, the equipment being used while fishing is harming the living organisms such as corals and sponges along with many more.
“ Natural gas industry has been identified as a major source of water pollution “ ( source 1 ). This quote from source 1 explains how out of all the ways of polluting the oceans, oil is always one of the worst. “ 8 million metric tons of plastic trash enters the sea from land every year “ ( source 4 ). This quote from source number 4 explains how every year tons and tons of plastic from land, gets into the oceans and continues to pollute. Garbage is polluting the oceans so much that the water is getting so bad, people are getting ill from drinking
The ocean is nowadays undergoing numerous environmental issues that further lead to marine pollution. Marine pollution is a very serious environmental issue that most of the countries of the world encounter. Aquatic littering is considered as one of the major causes of marine environment. The misleading use of the marine environment is extremely impacting the marine life and ecosystems. Moreover, the total amount of toxins and debris discharged by human beings is incredibly increasing in today 's world.
