Explain why oil exploration in the areas shown could lead to high economic and environmental costs. (10) The environmental effects of oil exploitation in these areas can vary depending upon the type, position and severity, however most pose the threat of being potentially severe. The explorations are taking place in deep water areas such as the Gulf of Mexico, the North Sea or the Arctic. Just one of the many potential risks and dangers of deep sea drilling is highlighted by the horizon oil rig spill of oil extracted from the sea floor. A spill in any of the deep sea areas would reduce the biodiversity of that area through reductions of bird populations, fish-stocks and populations of marine mammals.
Oceans are being polluted by substances such as farm fertilizers, chemicals produced in factories, and harmful sewage from towns and cities (Claybourne 38). Trash and debris, especially plastics, are deposited into the oceans by humans. These objects can be mistaken as food by many species, which eventually leads to death. When species consume what looks like to be food, but in reality is hazardous waste, the animal contains that chemical inside of them. When a larger animal consumes the hazardous animal, it affects the entire food chain (“What Is Ocean”).
David Lesar is the Chairman and CEO of this company. ETHICAL ISSUE Halliburton was one of the companies that were responsible for the world’s biggest oil explosion known as the Deepwater horizon oil spill in 10th April 2010. On the BP –operated Macondo Prospect Halliburton was one of the rig-operators. Lack of remote-control shut-off switch and proper cement mixing resulted in the oil spill disaster. Halliburton was also responsible for destroying evidence in Deepwater Horizon oil spill disaster in the Gulf of Mexico.
Unlike other organizations, BP was also changing with the dynamics of today’s business environment and was adopting new business strategies and management practices (BP and Verenium announce pivotal biofuels agreement, 2010). With this changing environment, the company faced an accident in the Gulf of Mexico situated in United States of America where 11 workers were dead. This is one of the biggest failures in the history of modern era, which cost near about 43 billion dollar and is continuing. Due to this disaster, company has to pay huge amount of fine to various authorities. This essay discusses about the situations of the company and tries to reveal what are the reasons are responsible for this failure.
Another problem is trash lifted by the tsunami waters from anywhere and everywhere, including debris from the earthquake disaster, has also been released and swept out to the ocean. The ocean’s waves and currents distribute the trash, along with the nuclear waste, throughout the waters, polluting the environment, near and far. Along with the physical devastation of getting infrastructure usable again, Japan is faced with environmental issues and daunting health concerns that must be improved, if not solved. The Fukushima Daiichi nuclear power plant is one of the largest and oldest plants in the world existing for over 40 years now. It is now facing great threat due to the recent natural disasters.
Hydrofracking is a process of drilling for natural gas that involves pumping millions of gallons of water and sand leaving incredibly dangerous and lethal amounts of chemicals and carcinogens in the earth. This process has allowed millions of gallons of deadly chemicals to contaminate rivers, creeks, irrigation systems, underwater currents, and drinking water. As hard as it may be to believe, hydrofracking is actually protected by a series of laws that permits this hideous process to proceed with little to no state or federal regulations. With more stories like John’s surfacing and more and more evidence that hydrofracking has created several serious environmental and human health problems, it is now clearly
TMA 01, QUESTION1. Some of the most serious environmental issues today are climate change, air issue, waste and land pollution, over population and water issue. 1. Climate Change, is undeniable a global environmental concern that is triggering a rise in the amount of major natural disasters like floods and hurricanes; which causes destruction in societies and the regions which they effect. Global warming will only cause an increase in these issues along with additional problems that could eventually end this civilization, if we don’t work hard on improving our efforts on managing all the different types of pollution and waste that contributes to this major concern.
It is difficult to pin the contamination directly on fracking, but the possibility that chemicals and natural gas could mix with water sources is overwhelming. Each gas well will need millions of gallons of water per well to shatter shale and release the natural gas trapped thousands of feet underground. The Majority of the water used in fracking remains underground where it can potentially leak into and contaminate underground water sources. Whereas, a portion of the water, better known as wastewater, returns to the surface, where it can contaminate nearby water sources if not disposed of properly. Unlike the water used for agriculture purposes that remains a part of the water cycle, water used for fracking cannot be recycled.
Since fish is the main target of mercury contamination, humans are at a lifethreatening risk by toxic effects mercury. Thus, production of toxic methyl-mercury in the upper ocean due to bio-accumulation and build-up of this poisonous compound in marine food web due to bio-magnification is of a vital concern for the humans. Study of marine biochemical cycle of mercury with its potential sources and sinks is really necessary to find effective remedies to diminish the dangerous effects of this shiny-white metal. This review presents biological and physical processes that drive biochemical cycle of mercury in the global oceans with the potential sources (such as river, atmosphere, sediments, and hydrothermal vents) and sinks (such as bioaccumulation in marine fish, and scavenging due to sinking particles). Spatial, vertical and temporal variations of elemental mercury and human exposure to deadly effects of methyl-mercury are also presented in this study.
The three types of fossil fuels are coal, crude oil, and natural gas. They all take millions of years to form, so they are considered to be “non-renewable”- eventually, the fossil fuels will all be used up. One dangerous biological effect of using fossil fuels is ocean acidification. Extracting and transporting fossil fuels can also be very dangerous. Environmentally damaging accidents such as groundwater contamination, land subsidence, and oil spills occur frequently.
