The marine environment is in danger of serious and sustained pollution. This is a biological issue, but also one with strong ethical implications. In terms of act utilitarianism, the choices we make and policies frame are based on practical outcomes and must be evaluated in terms of achieving maximum benefits from amongst a set of possible outcomes. This is a significant challenge for today’s world. The topic drawn for the report will be pollution and exploitation of marine environment. Pollution is one of the major issues affecting the marine life (Allen et al. 2012, p. 2817).
Synthetic pollutants discharged from industries such as pesticides, chemical fertilisers, oil sewage, herbicides, and plastics are diverted into the water bodies, which affect the marine life. This contamination affects the food chain and respiration problems globally (Zbyszewski & Corcoran 2011, p. 367).
Oceans cover 70% of earth`s total surface. Marine contamination affects the physical and biological characteristics of the coastal area, which threatens the marine ecosystem and affects its quality (Mambra, 2017). The major causes of marine pollution are discharging of effluent from industries, human activities, and solid waste run off to rivers and seas. Due to increasing environmental loss, there is an abundance of damage to the lives of coastal habitats (Ommer et al. 2012, p. 320).
Marine pollution has adverse effect on both sea turtles and their food. The marine pollutant kills aquatic life and destroys feeding habitats for sea creatures. For example- Small marine creatures are on the lower level of the food chain such as plankton who absorbs toxic chemicals. These chemicals accumulate in animal`s body, which concentrates toxins in the surrounding water. With the continuous flow of food chain, large animals such as sea turtles consume small sea creatures as its food that increases density level of chemical and pollutants in the water.
Pollution is a man-made activity and has to be considered as a major ethical problem. The addition of plastic to the environment is an outcome of improper disposal. Since plastics are lightweight, they have the feature of covering long distances and floating on the water surface. Floating plastics end up in mammals’ stomachs or around their necks. Extra nitrogen nutrient can create algae blooms. These algae blooms use all the oxygen present in the water. The level of oxygen drops causing a threat to marine life (Brown 2018).
The appearance of eroded plastic bags is similar to the food they eat. Fishes eat micro plastic, which resembles phytoplankton. Swallowing plastic debris reduces the stomach capacity, hinders growth, and blocks the intestines (Ouyang et al. 2015, p. 310). Eighty percent of plastic floating on the sea surface is expected to create heaps near the seashores. The density of plastic has been multiplying increasingly over several decades. The water supply is being put under severe threat due to the population explosion, pollution, and overuse. Polluted drinking water has become a cause of child mortality (Golden et al. 2016, p. 318). Around 1.9 million children have lost their lives due to contaminated water (Khuroo 2015, p. 45). Meanwhile, the density of plastic has increased from 4256.6 pieces km-2 to 8966.3 pieces km-2.
Scientists have discovered that most of ocean oxygen comes from tiny plants called phytoplankton. The high concentration of plastics in seawater causes oxygen saturation is a major factor of decline in fish population (Halle et al. 2016, p. 5669). These sites without oxygen are known as dead zones. Another cause of the unbalanced food chain is acid leaching from mines that drops the pH level of seawater, and the high content of sulphate harms the marine life. The marine ecosystem near coastal areas is being threatened by aquatic pollution and urbanisation. Reportedly, the Mississippi river contains nearly 1.5 million tons of pollutants and carries it to the Gulf of Mexico (Mallin et al. 2015, p. 407). Dumping the industrial waste and sewage in the water bodies is the cheapest way to dispose wastes. Industrial wastage contains mercury, DDT, and cryolite, which eventually brings the ecosystem under threat (Mambra, 2017).
To solve ethical problem using ethical theory utilitarianism-
The aim of the question is to explore exploitation of the marine environment through the lens of utilitarian theory. Utilitarian theory turns an ethical lens on marine wildlife. The ethical theory of utilitarian extends and brings moral concern to animals. Business organisations utilise available resources to maximise profit to attain economic benefits from the human perspective (Allen, Jarvis, Sayer, & Mills, 2012, p. 2817).
There is nothing wrong in using resources to meet the business aims but there is a need to reduce the negative impact of an imbalanced ecology and loss of marine life. The central idea regarding utilitarian is the act of decision making which satisfies all the interested parties. Utilitarian is recognised as universal because it always thinks of an action that does not harm anyone and anything. It is considered as a welfarist ethic that focuses on maximising gain and pleasure and minimising pain (Mambra, 2017).
The utilitarian theory demands critical examination of benefit claims to check whether the benefit claims are valid or not. Utilitarianism implies that every human or non-human activity should be considered equally while evaluating decision-making actions. However, from birth until death, the environment lends its resources to humans to spend their life. Nature and the environment can fulfil various necessities of human existence. One major initiative towards protecting the marine and environmental ecosystem is to make available peaceful and secure homes for different living animals (Mallin et al., 2015, p. 407).
Excessive nitrogen content in a marine ecosystem creates dead zones. People focus on working and satisfying their own interest and selflessness. Many ethicists argue that utilitarianism must be complemented by more principles to justify maximum welfare production. Environmental ethics creates an ethical relationship between people and the environment they live in. Utilitarianism is a consequentialist theory in which actions are either wrong or right depending on the result of decision (Ommer, Perry, Murray, & Neis, 2012, p. 320).
Utilitarian theory is identified as a teleological theory (Sigler, 2014, p. 4). The concept of maximising happiness over pain is considered profitable when it applies to environmental ethics. For example, in order to handle the issue of the greenhouse effect, the government decides to plant trees to reduce co2 and maximise clean air. The ethical theory of utilitarian will give more weight to long-term effects rather than short term (Dobson, J 2011, p. 220). However, spending lots of money on planting trees can be expensive for the economy. Directly or indirectly, the government collects its taxes from the public and society, which may prove financially onerous to the public reducing their personal disposable income. Planting trees covers hectares of land, which reduces the space for industry establishments, hampering the growth rate. Due to less available space, the growth rate becomes gradual and slow. It is not necessary that every human contribute actions to protect the environment. Taking responsibility for oneself to save the natural resources of the planet is doing one`s duty for the environment (Tupper et al. 2015, p. 39).
Problems are solved to achieve long-term sustainable growth. However, it is crucial to solve the ethical problem of the loss of the fishery ecosystem. The issue of loss of biodiversity associates risk with cultural identity, risk of regular degradation of the marine ecosystem, loss of capacity for breeding the remaining species of fishes. The entire ecosystem is being disturbed and depleted due to human intervention. The loss of the marine ecosystem led to a decrease in food supply for coastal residents and increased economic losses for the stakeholders such as government, coastal developer, policy maker, and conservationist (Rummel et al. 2015, p. 137).
Many people live around the ocean and depend on fisheries for their food. FAO (Food and agricultural organisation) indicates a red signal for the exploitation of total marine resources which has already reached 50 percent and remaining 25 per cent are overexploited, and rest of fisheries around 25 percent could be at risk in next few years (Ocean Atlas 2017, p. 20).
By solving problems related to contamination of marine ecosystem, it helps to achieve balance of ecosystem. Environmental dimensions by severe actions such as reporting of pollution violation like illegal and hazardous waste. In most areas, people are not even concerned and aware of ecosystem imbalance. Socially, it is a society’s responsibility or obligation to take care of ecology surrounding them. More often, the environment suffers from various careless human activities. Misinformation and disregard of Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) can cause negative effects on the interaction of living beings on the planet. For this social problem, the government should create awareness programs related to ecological problems.
While working in industries, humans feel that their lives are being affected due to industrial neglect. Human health is affected in many ways such as labour work in dangerous industries and plants. Human intervention causes ecological imbalance because of dangerous fuel emission vehicles. Recycling and reusing can help the industries in some ways to avoid the problem of disposing and littering everything. Recycling enables us to utilise those parts of resources that are not expected to be used such as large material quantities of junk material paper, packages, newspapers, jars, and bottles. However, nowadays both governments and businesses keep waste paper so it can either be recycled or used to make new products. The sustainable growth and the living time of the planet will increase if people show enough concern and commitment to eliminate pollution from the environment, which will lead to sustainable growth and serve future generations as well (Dobson, 2011, p. 215).
