Dispersants cause the oil to break up into smaller droplets, which become miscible in water. However, these dispersants may result in more ecological harm than good. The chemicals contain nonbiodegradable toxins that can kill fish and migrate great distances. Dispersants also are blamed for the massive oil plumes several hundreds of feet underwater, harmful to all aquatic life, especially fish larvae and filter feeders. Moreover, because of the large volume of oil that has been spilled, the amount of dispersant required and the amount of oil dispersed simply suppresses the problem, rather than solving
Alex Grommesh Ms. Heise/Ms. Keel English 2 16 March 2018 The Negative Effects of Water Pollution The majority of all marine ships dispose of their waste by throwing it into the sea (Wroble 41). If they are caught doing this they can be charged for littering and be given anywhere between a three hundred to a two thousand dollar fine (this fine can be more or less depending on where it occurred). Furthermore, if what is being dumped is considered hazardous to the environment a jail sentence can be given to the perpetrator (“
The teams were conducting checks on the day of the disaster to find out if the well had been properly sealed. Eight Safety System Failures Dodgy cement According to BP the cement formulation appeared not to have been up to standards therefore it did not create a seal at the bottom of the borehole, causing a leak allowing oil and gas to leak into the pipe leading to the surface. Valve
The chemical actually has absolutely no benefit to the human body. The National Wildlife Federation states that mercury can “adversely alter the neurological and reproductive systems of humans and wildlife.” (Tolmé 2012) Mercury has the capability of damaging the nervous system including “the nervous system including psychotic reactions, hallucinations, suicidal tendencies and delirium” (Edward 2012)
Tenebrosa, factors caused by living things, known as biotic factors, also play a role in the distribution of P.Maculata. The first important biotic factor key in a P.maculata’s life is predators. As mentioned prior this organism is unable to move quickly in the water and like all organisms in the ocean is hunted as a means of food. As it cannot ‘outrun’ predators the organism, to deter predators, releases a unique toxin identified as tetrodotoxin. This toxin is extremely harmful and successfully enhances the survival of P.Maculata.
Dispersants are a special type of chemical that when you drop in the water contaminated with oil it will break apart the oil into small little droplets. The droplets will take some time, but over a course of several years, the droplets will naturally dissolve into the water. Dispersants are a great way to clean up an oil spill, but we also need to make sure that spills will not happen again. One of the ways to prevent spills is too use government regulations. After the Deepwater Horizon explosion, the United States Government made PB pay $4.5 billion in a criminal settlement with the Justice Department, and an additional $14 billion for cleanup.
People inhale oil fumes and suffer with asthma. There are a million ways that oil is destroying human lives, but if we get off land and go underwater, oil’s damaging effect on the oceans’ habitats adds the more reasons to strive for the use of alternative energy sources. Since oil began to be used widely as a fuel, there hasn’t been a year without a copious number of oil spill incidents. In the US alone, the Office of Response and Restoration of the National Oceanic and Atmospheric Administration (NOAA) responds to over a hundred oil spills each year (NOAA). While spills happen on both land and water, ocean spills are much more difficult to contain and recover from.
BP, with the assistance of government agencies and others, worked together to manage the spill and mitigate its impact on the environment and human health by eradicating and dispersing the oil offshore, and by executing strategies to preserve the seashore and clean up oil that came ashore. Besides, there is still 28 percent of oil in the sea (Bryant, 2011). Every disaster is followed by fatalities, however, this disaster had double or even triple number of losses than any other disasters. The Gulf oil spill not only affected sea and marine life, but also humans who were used to live on the coastline.
This shows that all of the people within an area that has fluoridated water would suffer various negative consequences because of the chemicals in fluoride; however, because it is in an approved small amounts of fluoride, it does not negatively impact the health of the people tremendously, but in a positive way since tooth decay is decreased while consuming a liquid that contains the nutrients of fluoride. “The naturally occurring levels of fluoride in fruits, vegetables, meat, grain, eggs, milk, and fresh water supplies are generally very low (less than 0.1 ppm” (Fan’s Grocery Store Guide).
As clean as wave energy is, it still creates hazards for some of the creatures near it. The large machines that are in the water disturb the seafloor, change the habitat of near-shore creatures (like crabs and starfish) and create noise that effects the rain . There is also a danger of toxic chemicals that are used on wave energy platforms spilling and polluting the marine ecosystem around them. Another downside is that it disturbs commercial and private vessels. Power plants that gather wave energy have to be placed by the coastline to do their job, and they have to be near cities and other populated areas to be of much use to anybody.
Further, the increased in chemical levels decreases the immune strength of the sea otters which indirectly leads to death. The speaker refutes this point by saying that, dead sea otters are seldom seen on the shore which indicates that the sea otters are
The acidity doesn 't just effect the fish but it effects human beings. Just as the acidity hurt Mark and Sues business, it could hurt other business that are also involved with the oceanic wild
Hydrofracking causes fissures, which can allow harmful gases, radioactive material, and chemicals to escape underground as well (Hoffman). The impact of hydrofracking on water sources is not just a problem in theory. For example, it was confirmed by the Environmental Protection Agency that the residents of Pavillion, Wyoming have “contaminated ground water” caused by fracking operations in that area (Hoffman). Wyoming is not the only state to report contamination, as at least 8 others have reported impacted water as well (Fracking: The Dangers). Hydraulic fracturing’s overuse of water as well as the risk for groundwater contamination begs the question of why this method is
When the salt water is extracted from the fresh water, the salty ‘brine’ is put back into the ocean where it sinks to the bottom because it is denser than normal sea water. This could have unknown consequences but because the process is so knew it is hard to tell how detrimental they will be. It is issues like that which have stopped a plant like this being built in the past. However, after extensive reviews and approvals it has been stated the the plant will not be loud, produce odor or have an environmental impact. It has also been stated that the plant "will have significant economic benefit for the region, including $350 million in spending during construction, 2,400 construction-related jobs,
Hydraulic fracturing, or fracking, is a method used access the natural gas that exist in the shale formation layer which is around 6000 feet below ground, in a cost effective way. After fracking horizontally, they blast the water mixed with salt and chemicals into the bedrock. Due to high level of pressure shale is cracked and the gas bubble is released. Natural gas flows back to the well head at the surface. This method of gas extraction has never previously been used on such a wide scale as its being used now.
