Introduction:

Oil spills are a serious problem all over the world. It is widely known that oil is the very important resources in human daily life. In this research paper, I will discuss how government and environment scientists have to solve this situation. Billions of dollars are lost and it is an oil spill disaster management so as to rehabilitate the environment. Many countries are focusing on finding a safer ways to transfer oil between countries and remedy the spills. As a worldwide problem, the public should pay more attention to the consequence of oil spills, to prevent the advance effects and seek a preventative measure of the long-term effects associated with oil spills.

Thesis statement: Oil spills cause both short-term and long-term environmental destruction, some of the effects of oil spills can be long-lasting. This research paper looks into the cause and effects of Oil Spills

Cause and Effect Pattern, Problem

Oil spills in water bodies such as rivers, lakes bays and ocean or along the pipelines are usually as a result of accidents which may involve oil tankers, breakage or linkages on the pipeline storage facilities or accidents on the drilling rigs. More often than not these spills are caused by human errors or negligence during operations sometimes equipment's may break down resulting in oil spillage. Another cause of oil spillage is natural disasters such as hurricanes and earthquakes. When they occur they result in massive destruction of the oil storage and drilling facilities. More often than not, a majority of oil transportation facility does not withstand the impact of earthquakes hence they break down causing spillage. In recent years there have been reported spillages caused by deliberate acts e.g. by terrorism, war and vandalism. Illegal dumping of used engine oil and grease has also emerged as a major cause of oil spills.

Oil spills have two major categories of effects namely economic and environmental effects the effects are similar for both patterns only that the large spills have a far-reaching effect. To begin with, we shall look at the environmental effects. Oil spill covers the shoreline with oil residue, as a result, it becomes difficult for plants to thrive. When it occurs on the land, it covers plants, therefore, hindering transpiration as a result plants wither off and die. Aquatic animals choked to death. When the pattern is large the young once of wildlife animals may starve to death because the oil covers there skin making it hard for the mothers to detect their natural smell. Marine oil spills destroy plankton and collar reefs (Ramseur, 2015).

Heavily furred sea mammals subjected to oil spills are afflicted in similar ways. Oil coats the hair of sea otters and seals, lowering its insulating result and resulting in fluctuations in body's temperature and hypothermia. Oil can also blind a creature, giving it defenceless. The ingestion of oil triggers dehydration and impairs the intestinal process. Pets or animals can be poisoned and could die from oil joining the lungs or liver.

In addition, engine oil spills can also damage the quality of air. The chemicals in crude oil are typically hydrocarbons which have dangerous chemicals such as benzenes and oxygenated polycyclic aromatic hydrocarbons. These chemicals can create adverse health results when being inhaled into the body. Furthermore, these chemicals can be oxidized by oxidants in the atmosphere to create fine particulate subject once they evaporate into the atmosphere. These particulates can permeate lungs and hold toxic chemicals into the human body. Losing surface oil can even be a source of air pollution such as soot allergens. Through the cleanup and healing process, it will generate air contaminants such as nitric oxides and ozone from boats. Last but not least, bubble bursting can even be an era pathway for a particulate subject during an oil spill. Quality of air monitoring data has revealed that requirements contaminants experienced exceeded the health-based standard in the coastal parts (Corchado, 2017).

Oils spills are very expensive to manage. Other than the cost of managing and compensation cost oil spillage has a trickle-down effect that may affect other economic infrastructures. An oil spill in Delaware River in November 2004 resulted in a temporary shut down of Salem Nuclear Plant- which uses river Delaware water for cooling (Ramseur, 2015).

Problem Solving Pattern

There is two oil spill problem-solving patterns namely Case-Based Reasoning (CBR) methodology and the Weighted Voting Superposition (WeVoS) –this is an algorithmic oil spill solving a problem which uses superposition of map to compare changes due to oil spills hence determines the extent(Cohen, 1986). CBR is a methodology deliver from computational solutions designed by analysis of similar but previous solutions for problems that had occurred in the past. These problem-solving models are used for environmental sensitivity mapping in the following ways;

Shoreline type: Shoreline type is categorized by getting ranking depending on how easy the marked site was prior to the spill in order to clean up, just how long the oil would persist, and exactly how delicate the shoreline may be to the floating oil the effect of the oil spill when they reach offshore is determined .

Biological resources; Problems are taken into account when ranking natural resources are the observance of a sizable amount of people in a tiny area, whether special life levels arise ashore (nesting or moulting), and whether there are types present that are threatened, endangered or rare

Infrastructure /utility resources; split into four major classifications; archaeological importance or ethnical learning resource site, high-use recreational areas or shoreline gain access to points, important secured management areas or learning resource origins. A few examples include international airports, popular beach sites, natural reserves diving sites sea sanctuaries and marinas,

After an environmental sensitivity is done indexing a cleanup is usually the final step in risk control of an oil spill .the following methods are used during clean up.

Controlled burning up can effectively decrease the amount of oil floating in water if done properly. Nonetheless, it can only be achieved in the low breeze and can cause polluting of the environment. Proper assessment should be done first.

in order to dissipate oil Dispersants may be used. It is usually a colloid, dispersants are polymers that are used to prevent clumping or settling or oil granules -

Dredging: for oils dispersed with detergents and other oils denser than normal water can be dredged

-Skimming: Requires still water all the time through the process is very tedious and expensive as water wave will always disrupt the process.

Comparison of the two methods

This method involves a classification database network and retrieval. The network is constructed using algorithms for result summaries of the ensemble self-organizing map. The maps are then analyzed for the purpose of the present study. On the other hand, the Weighted Voting Superposition (WeVoS) usually aims at achieving the best topography his order that can be used to the dataset in the map unlike CBR, WeVoS uses information. Salinity, pressure-temperature.in combination with a number of satellite sticks to determine with accuracy area with spills in relation to historical data (Cohen, 1986).
