The first and foremost is the oil spillage in the ocean which leads to ocean acidification. This brings a huge threat towards the environment and the marine wildlife. Oil operation in sea bed often requires drilling fluids such as mud which are used to inject into the wellbore to lubricate the drilling bit. These devastating effects of numerous oil spills on the surface of the ocean could bring a long term environmental effect to the coastal areas as well as to the sea bed. Besides, drilling mud which contains toxic substances like benzene, zinc, arsenic, radioactive materials, and other contaminants are used to lubricate drill bits and maintain the pressure in the drill.
This makes boat owners very vulnerable to a non-profit year. On average, a boat fishing for King Crab makes around $850 million. Boat owners get 50% of that which leaves them with $425 million with expenses still remaining (Alaskan Seafood, 1). “Owners are accumulating costs of about $1,000 a day for such expenses as insurance, mortgage fees and food for crew members” (Deadliest Catch' Fishery, 1). Holding the boats just days before the season starts, and the accumulating cost of sitting at the docks, has frustrated many boat owners.
What is an oil spill? (JDB) An oil spill is a type of pollution which consists on the dumping of petrol into the environment, mainly into oceans although it can also occur on land. These oil spills are mainly caused by the release of crude oils, wells, platforms and drilling rings. These oil spills, can very well damage the environment and therefore causing many consequences to different groups of animals and pollute the area where the dumping took place. Deepwater Horizon spill (MBR) This devastating event began the 20 of April 2010 in the Gulf of Mexico.
This can result in lung, kidney, and liver damage, as well as death from toxins. Oil spills also have indirect effects on these mammals, such as habitat loss and a diminishing food supply. Lastly, the oil slicks can make animals blind from continuous exposure. Because oil spills cause so much damage, many marine mammals die because of it. Whales, including dolphins,
Millions of people rely on fishing for their livelihood and nutritional needs and they need help. A. With the overfishing, many families in 3rd world countries will not have food. 1. If overfishing continues hundreds of thousands of fish farmers and medium scale fisheries, often very poor, that depend on aquaculture and fishing, will be out of work.
Even though the manatee deaths were not determined many believe that itś the oil spill that killed them. In 2010 because there were so many oil spills happening and the manatees were so endangered rescue clinics were not allowed to release the manatees until the water was cleared up (Phillips). Chemical and nutrient pollution has also been very harming to the West Indian manatee. In 2013, 15% of the manatees died mostly due to the sewage and fertilizer runoff into streams and rivers that dump into the ocean (Guest). Agriculture immensely adds to the nutrient and chemical pollution due to the fertilizers used on crops.
It was found out that the disposal wells pumped with used fracking chemical water are creating these man-made earthquakes. “If you pump water in a fault, the fault can slip, causing an earthquake.” https://stateimpact.npr.org/texas/tag/earthquake/ These earthquakes, no matter how big or small are bothersome to a person 's
Many people are familiar with tanker accidents, since they are highly publicized, and they release large volumes of oil into the ocean. Only a small percentage of global oil spills are related to tanker accidents due to explosions, hull failure, or running aground, however. These spills tend to be very harmful because of the sheer volume of oil released at once, and they pose a serious threat to marine animals and seabirds. Such disasters frequently bring attention to issues with safe oil handling, which can lead to reforms in petroleum regulation. Oil spills in the water can also be caused by natural seepage.
Used solvents contain contaminants that can be removed by fractional distillation. The recycled solvents have purities suitable for re-use. Fractional distillation is used to separate the crude oil into its various components such as gasoline, kerosene oil, diesel oil, paraffin wax, liberating oil. Fractional distillation is also used for the purification of water. Water contains many dissolved impurities; these can be removed by this process.
It’s perceptible that the ocean’s economy is really important, however but due to overfishing, it is costing many people their jobs. An example of this is, in 1992 when the cod stocks in Newfoundland have depleted to the point where the fisheries had to close down. 40,000 people were put out of work due to the low stocks. At first, it was supposed to be a two- year closure to let the cod replenish. After those two years, there wasere even less cod.
