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
PCBs, a type of chemical in coolants, are almost completely harmless to fish, but when a bird eats a fish that has PCBs in them it will affect the strength of their eggs (Wroble 47). When the eggs are weaker like this the mother can not warm them because if she does she will break them. This causes a plumite in the bird population and can make a few species endangered. Another chemical
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) An extended exposure of mercury can cause muscular spasm and can also lead to death. Once mercury enters the body, it is stored in “kidneys, blood, spleen, brain, liver, bones and fatty tissues.” (Edward 2012) The metal also has a big impact on pregnant or nursing women. It can contaminate breast milk and can increase the percentage of neural tube defects by the utero being
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.
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. The United States Government did a good job in making B.P pay for their mistakes, but the
Oil burns and releases toxins and CO2, poking holes in the ozone layer. 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).
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. From the sociological perspective, it was a huge social, cultural, economic and psychological threat for the communities living across the coastlines, cleanup workers, and especially children.
Although it is argued from a consumer’s point of view that water fluoridation is dangerous and hazardous to those who practice and use it, if it truly were hazardous, there would be a massive outbreak with everyone and it also would not have been approved from the Public Health Service since not only does it just affect one person, but a whole group of people since these are community water sources. 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).
Landlocked nations and cities far from the sea have to find alternate sources of power, so wave energy is not the clean energy solution for everyone. 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.
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
My opinion on the video is that we need to find ways to prevent the wide spread of acidity that is increasing over time across our earth. 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
Unaccounted water that is not put into waste wells may stay underground; however, its chemicals can make their way into the water supply of the surrounding areas which causes contamination. 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).
Many people claim that desalination is an energy wasteful process, is extremely expensive and can damage the environment, particularly marine life. When the seawater is sucked in to be desalinated, plankton and fish and even birds can be sucked in and killed as well. 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.
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.
