...Atlantic Bluefin Tuna The species Thunnus thynnus, known as Atlantic Bluefin tuna, currently faces extinction. This highly valued and sought after species fetches high prices in fish markets. As a result, the widespread overfishing of Atlantic Bluefin tuna occurs. Because of this overfishing, the population of the species declined by an estimated 51% in the past 39 years, as reported by the International Union for the Conservation of Nature (IUCN) Red List, which lists the species as endangered. Due to the continued threat of overfishing and the lack of effective conservation efforts, the Atlantic Bluefin tuna population continues to decline, which if allowed to continue will result in the extinction of this species and a resulting cascading...

...The Decline of Tuna due to overfishing Tuna are remarkable and impressive wild animals. The Atlantic bluefin can reach ten feet in length and weigh as much as 1500 pounds (more than a horse). Their specialized body shape, fins and scales enable some species of tuna to swim as fast as 43 miles per hour. Tuna swim incredible distances as they migrate. Some tuna are born in the Gulf of Mexico, cross the entire Atlantic Ocean to feed off coast of Europe, and then swim all the way back to the Gulf to breed. These extraordinary marine animals are also integral to the diet of millions and are one of the most commercially valuable fish. The majority of the market is made up of four species: skipjack, yellowfin, bigeye and albacore. As the methods of catching tuna have improved over the years, the conservation and management of tuna has not evolved as quickly. According to the United Nations Food and Agriculture Organization, most tuna stocks are fully exploited (meaning there is no room for fishery expansion) and some are already overexploited (there is a risk of stock collapse). The once abundant Northern Bluefin Tuna (Thunnus Thynnus), which lives throughout the Atlantic Ocean and the Mediterranean Sea, is plunging in a free fall towards extinction. The Northern Bluefin Tuna population has a slow growth rate and also a late sexual maturity age. Bluefin larvae have a 1 in 40 million chance of reaching adulthood, an extremely low number for an endangered species. The Bluefin mature...

...Overfishing of the Atlantic Bluefin Tuna The Atlantic bluefin tuna is the largest species of tuna and lives near the top of the food chain within its ecosystem. Powerful and strong, they are known to have large appetites and a varied diet which allows them to grow to an average size to about 6.5 feet long and weigh up to 550 pounds, though some specimens have been known to be much larger. These fish are highly migratory, with distribution ranging from Newfoundland and Iceland to the Atlantic coasts of Brazil and Africa. Bluefins can be most commonly found in subtropical areas of the North Atlantic Ocean, the Mediterranean, and Black Seas. The fish typically grow slowly and are relatively late to mature. There are two known spawning areas of these tuna; the Gulf of Mexico and the Mediterranean. This knowledge and improved fishing techniques have brought in higher quantity catches over the years. However, the conservation and management of the tuna hasn’t changed quickly enough along with these techniques to address the depletion of stock in the Atlantic. Over the past 40 years, the International Commission for the Conservation of Atlantic Tunas (ICCAT) reported a decline of 72% in the population of eastern Atlantic and Mediterranean stock and an 82% decline in the western Atlantic stock (NOAA(a) 2009). The bluefin population has been continuously declining for several years and despite some measures being taken to manage the population in the Atlantic, it still remains...

...and Rebuilding Efforts of The Western Atlantic Bluefin Tuna Population Give a man a fish and he eats for a day; teach a man to fish and he eats for a lifetime. Juxtaposing this proverbial advice with the reality of Thomas Malthus’s Theory of Population reveals a disastrous truth: as the number of fishermen exponentially increases, the fish supply progressively declines. Unfortunately, a Green Revolution that would, in theory, save the plundering fish population has yet to emerge from the depths of science laboratories. Instead, the fishermen who were promised to eat for a lifetime are required to limit their taking from the bounty in an effort to reverse the Malthusian inevitability. This depiction is more than a hyperbolic tale to scare away hungry fishermen. Rather it is a phenomenon that is swimming its course across the Eastern coast of The United States as the Western Atlantic bluefin tuna battles to sustain viable population levels. The Western Atlantic bluefin tuna population is officially acknowledged as an endangered species by the International Union for the Conservation of Nature. Coupled with the commercial success of the species, the diminished populations have necessitated strict government regulation. Nevertheless, the bluefin tuna remains a common resource subjected to the constraints of economic hunger, creating an inefficient market that reflects the differing interests of stakeholders. The bluefin tuna industry is relatively young: according...

...Shark Finning in Hong Kong: What are the social and economic factors of shark finning in Hong Kong and how will it have an affect on the remaining population of sharks? Victoria Abstract The rapid economic growth in Hong Kong over the past few decades has had an immense effect on the amount of shark finning taking place. With GDP steadily increasing the recent change in the spending patters has only contributed to an overuse of this resource. The pricing patters of this product show that as long as fishing remains economically viable sharks will continue to be at risk of extinction. There has been a lack of motivation to raise awareness on this topic and as long as fishing remains economically viable it will just continue to occur. To reduce the amount of shark finning in Hong Kong we need to enact more ant-finning regulations. Keywords: finning, Hong Kong, disposable income What are the social and economic factors of shark finning in Hong Kong and how will it have an affect on the remaining population of sharks? Shark fins are a valuable product and a delicacy to people in Hong Kong and many other surrounding populations that are heavily Chinese, but this overfishing has led to a major depletion of the shark species. Although several countries have made the effort to ban shark fishing, if it continues to happen at the current rate there will be a risk of extinction. Hong Kong has only increased their amount of shark fishing because of the recent growth and expansion...

...generation. “Our Stolen Future”, the scientific discovery of Theo Colborn, Dianne Dumanoski and John Peterson Myers, takes up where Carson left off and reviews a large and growing body of scientific evidence, linking synthetic chemicals to aberrant sexual development and behavioral and reproductive problems, such as low sperm counts, infertility, genital deformities, hormonally triggered human cancers, like those of breast and prostate gland, neurological disorders in children such as hyperactivity and deficits in attention. The quality of men's sperm declined steadily in the early years of the 21st century until hardly anyone could reproduce in the normal way. Meanwhile, the countryside was virtually emptied of animals as natural populations crashed. The first signs of the impending catastrophe were noted in the 1990's, but few people then believed that a cocktail of pollutants that mimic human hormones could have such profound effects. So nothing was done until it was too late. Over the last few years, an increasing number of...

...Collapse- book is about a history topic about how societies choose to fail or survive. The main characters are historical people and unknown kings of Mayan cities or Easter Island villages. Jared Diamond tells the story of the Viking explorer Erik the Red, who discovered Greeland and Vinland (Terranova, in Canada). Another character is captain Olafsson, a norse sailor who wrote the last news about Greenland in 1410. Another main character is Christopher Columbus, who arrived at Hispaniola in 1492, but now this island is two countries, the Dominican Republic and the Haiti. Diamond studied the politics of two presidents. the dominican Rafael Trujillo, who protected the enviroment and the dictator François, Papa Doc, Duvalier, who decided on politics of deforestatation of his country, Haiti. The author considered the bad politics of another main character, king George II, who was interested in sending merinosheeps from Spain to Australia, an idea which was succesful from 1820 to 1950 but then the farmers understood their lands lost fertility. Another main character is Tokuwaga Jeayasu, a shogun of Japan in 1600, who prohibited Christianity in 1600 and protected his country againt deforestation. The book takes us to a lot of places around the globe: Mayan cities, Rwanda, Viking colonies of Vinland or Greenland, Haiti and Dominican Republic, Easter Island and Polynesian colonies in Pacific, and the Chaco villages in New Mexico (United States). The time period was from 800 AC, when...

...Bad Bug Book Handbook of Foodborne Pathogenic Microorganisms and Natural Toxins Introduction Food safety is a complex issue that has an impact on all segments of society, from the general public to government, industry, and academia. The second edition of the Bad Bug Book, published by the Center for Food Safety and Applied Nutrition, of the Food and Drug Administration (FDA), U.S. Department of Health and Human Services, provides current information about the major known agents that cause foodborne illness. The information provided in this handbook is abbreviated and general in nature, and is intended for practical use. It is not intended to be a comprehensive scientific or clinical reference. Under the laws administered by FDA, a food is adulterated if it contains (1) a poisonous or otherwise harmful substance that is not an inherent natural constituent of the food itself, in an amount that poses a reasonable possibility of injury to health, or (2) a substance that is an inherent natural constituent of the food itself; is not the result of environmental, agricultural, industrial, or other contamination; and is present in an amount that ordinarily renders the food injurious to health. The first includes, for example, a toxin produced by a fungus that has contaminated a food, or a pathogenic bacterium or virus, if the amount present in the food may be injurious to health. An example of the second...
