"Ocean Pollution and Its Impact on Coral Reefs
Introduction
Humans now dominate most of the earth's ecosystems, both land and water. Between one-third and one-half of the land surface has been modified by human activity and the carbon dioxide concentration in the atmosphere has increased by nearly 30 percent since the beginning of the Industrial Revolution (Vitousek et al., 1997). Species have been driven to extinction, particularly birds. At the present, scientists are even beginning to believe that human action might extinguish some marine species that spend their whole lives in the ocean (Malakoff, 1997). Multiple assaults on the ocean affect everything from fish to coral reefs. The intention in this analysis is to explore how ocean pollution affects coral reefs..."

From the Paper
"The term coral is used to refer both to the animal itself and to the cement-like substance it manufactures in its body to build a reef. The animal was long thought to be a plant. In 1726, a French naturalist named Jean Andre Peysonne found that these 'plants' were actually animals belonging to the phylum of coelenterates. Coral is a very simple organism. It has a tiny, transparent, gelatinous body enclosed in a tube with an opening at one end, and around this opening--which functions both as a mouth and as a passage to excrete wastes--is a ring of tiny tentacles ,which gather in the animal's food."

Abstract
This paper discusses the different kinds of coral reefs that exist. The author explains the various ways that coral reefs are formed, along with the factors that contribute to the growth of coral reefs. In addition, the author also analyzes the various theories centering around the formation of coral reefs.
From the Paper
"There are three different types of reefs. These are the fringing reef, the barrier reef, and the atoll. The fringing reef is a coral reef that attaches to the margins of islands and conti?nents. It consists of several types of corals without any predomi?nant type. It is surrounded by a few corals that are separated from the island or continent by areas of sand. The fringing reef forms an area along the shore and along the margins of the island where colonies of coral can grow. These reefs begin to grow below the low water mark and extend seaward. The fringing reef is always attached to the margin of the island or continent, and the edge lying sea?ward is not separated from the main land by a lagoon."

From the Paper
"Coral reefs are one of the oldest ecosystems in the world, existing for more than 450 million years. A coral reef is a type of biotic reef that develops in tropical waters. Coral reefs are found in all oceans of the world, generally between the Tropic of Cancer and the Tropic of Capricorn because the reef-building corals are living in this waters. A water temperature of 20 to 28?C is needed for growth of the coral reef. Massive reef structures are built over thousands of years by tiny coral polyps aided by minute algae called zooxanthellae that live in their tissues, calcifying algae, and other organisms that secrete calcium carbonate and adhesives. The process of reef formation is heavily dependent upon photosynthesis by reef-building organisms. Once formed, the complex, rock-like reef framework provides food and shelter for the multitudes of organisms that inhabit the reef. "

Abstract
Several recent studies show that the America's coral reef system in the Atlantic and Pacific Oceans are being degraded by natural and man-made factors. This paper examines the magnitude of the problem and addresses possible solutions. The paper argues that once coral reefs die, they are gone for ever and questions whether mankind can save their destruction.
From the Paper
"It remains to be seen whether these efforts would go far enough to address the urgency, which this matter requires. Policy makers should appropriate enough resources to address such problem. These are bold measures but unless the are aggressively implemented, the global Coral Reef system may be destroyed in the years to come, this is the reason why environmental pollution should be taken more seriously, the Kyoto conference held in Japan a few years ago was a right step and hopefully the leaders of the industrialized countries, who are also responsible for over two-thirds of the global industrial pollution should live up to their commitments to reduce industrial emissions. It is regrettable that President Bush?s Administration refused to live up to the treaty negotiated by members of the global community of which the United States was a party to."

Abstract
This paper introduces, discusses and analyzes the problem of ocean pollution, and how it is affecting marine life. It also looks at what is being done to control pollution in the United States and around the world. The paper shows that, as the world become more industrialized, the pollution in the ocean is becoming more of a problem.
From the Paper
"There are numerous pollutants contaminating the world's oceans ? they have been building up for hundreds of years, and they are both man-made and natural, although man-made pollutants are much more common than natural pollutants. Over 900,000 gallons of oil spills into the oceans every year, either from leaking tankers, oil spills, or leaks from oil dredging machinery. "In 1997, the 22 oil spills reported worldwide involved a total of 15 million gallons (57 million liters) of oil" ("Water Pollution")."

Abstract
This paper begins by providing a brief definition of coral reefs and their main characteristics. It then discusses the different ecological problems -natural and man-caused which are slowly destroying the reefs. These include eutrophication - when the algae which is in a symbiotic relationship with the coral overgrows the coral using the increased nutrient content of the water and in the process destroys the coral. It also includes over fishing, coral bleaching and tourism. The paper finally examines the various laws and acts which have been passed to try and avert this phenomenon.
From the Paper
"Coral reefs are widely known as the ?rain forests of the ocean?. Providing a habitat to innumerable varieties of marine species the coral reefs are an important part of the marine ecosystem. Occupying an estimated 4,00,000 square miles (0.17%) of the ocean surface the coral reefs sustain more than 25% of all marine life. [Washington College of Law]. However uncontrolled fishing, tourism and other environmentally destabilizing activities of man have seriously endangered the coral reefs. This situation is alarming considering the fact that damage to the coral ecosystem has serious implications for all the countless species that depend on it for their survival. Let us explore the ecological effects of coral reef damage and the environmental laws, which protect them in a little detail."

Abstract
The factors responsible for the reef devastation are directly attributed to human actions. This paper looks at the questions surrounding this destruction and offers many examples of why and what is causing the reef's destruction. In the end, the author recommends ways in which the destruction may be halted.
From the Paper
"For the last fifty years marine biologists have chronicled the deterioration and destruction of corals on reef systems worldwide. Coral reefs provide sanctuary for over a fourth of the world?s marine fish species and consist of as much biodiversity as tropical rainforests. Unfortunately, both are now disappearing at an astounding rate"

From the Paper
"Coral reefs are composed of a myriad of individual coral polyps which are living creatures encased in calcaceous shells, and reefs cover approximately one percent of the earth's surface (http://www.library.thinkquest.org/25713/corals.html).
They are the world's second most productive ecosystem behind rain forests. As they develop, coral reefs characteristically sink into the water, and the reef goes from being a fringing reef to being a barrier reef, to becoming an atoll. This paper will look at how fact and theory interact in Darwin's discussions and writings on coral reefs.
When Darwin undertook the voyage on the Beagle in 1831, his scientific training at Cambridge had been thorough, but outside the curriculum (Bowler, 157), his having been training for the ministry. Much of his knowledge of geology and natural history..."

Abstract
This paper studies the causes and effects of pollution in the world's oceans. The paper lists the causes of this pollution, including oil spills, tanker discharges, untreated municipal wastes and agrochemical residues. In addition to these major causes, the paper also includes a look at the smaller ,yet more common causes, such as medical wastes, beach visitors? garbage and waterfront businesses.
From the Paper
"An ocean organism's internal environment is highly influenced by many external factors. Many marine invertebrates are conformers and have the ability to thrive around the world. They have no need to control their internal environment since the external environment is fairly constant in terms of temperature, oxygen tension, and nutrients. However, with the threat of pollution, the marine invertebrates ability to live within the dirtied and toxic waters are compromised, therefore, resulting in fewer numbers for reproduction, production and harvest."

Abstract
This paper provides an insight into the coral reef, one of the most beautiful, living examples of nature. It discusses how it has taken thousands of years to create the coral reefs that are found worldwide and how these fragile ecosystems are in danger of disappearing unless citizens and the government take steps to preserve these habitats for numerous varieties of marine life. It shows how with the aid of satellites and concerned individuals, these living monuments will be around for thousands more years.

From the Paper
"Scientists are excited about the use of the satellite since it offers views of coral reefs that are hard to reach and observe. In 2000, when a fishing boat was grounded more than 1,000 miles west of the Hawaiian Islands on the Pearl and Hermes Atoll, scientists found it difficult to reach the reef to check on the amount of damage it may have sustained. There are numerous coral reefs in the Pacific Ocean that are so remote, that it would be hard to detect or study a spill or grounding. High-resolution imagery gives scientists a much needed tool to monitor these reefs that were previously inaccessible (Soliday 154)."
