...WHALE SHARK: ENDANGERED SPECIES DUE TO HABITAT DESTRUCTION CAUSED BY POLLUTION AND CLIMATE CHANGE Rhincodon typus, hereafter referred to as whale shark, has been listed as “endangered/threatened” by the U.S. Endangered Species Act (ESA). An endangered species is defined as “any species which is in danger of extinction throughout all or significant portion of its range…” Whereas a threatened species is “any species which is likely to become an endangered species within the foreseeable future throughout all or a significant portion of its range.” Whale sharks’ habitats are constantly being destroyed by the increasing levels of pollution in the oceans as well as by anthropogenic climate change. Their population is also dwindling as a result...

...Shark Research Paper You are more likely to get struck by lightning than to get eaten by a shark. Don’t let the word shark fool you, they are actually harmless creatures that are demonized greatly. There is a popular tagging group called Ocearch, and their goals are to protect and research the sharks. Protection of these beautiful majestic creatures are essential to the underwater world. Sharks such as Sophia, have many unique features. The longest whale shark recorded was 41.5 ft long. This shark was named after the size they get to. Whale sharks almost never attack humans and have no intention to. Even though they are as big as whales, they are not whales, which means that they are cold blooded and have to live in warm waters. As you...

...Shark Education What is Shark Finning? Shark finning refers to the removal and retention of shark fins and the discard at sea of the carcass. The shark is most often still alive when it is tossed back into the water. Unable to swim, the shark slowly sinks toward the bottom where it is eaten alive by other fish. Shark finning takes place at sea so the fishers have only the fins to transport. Shark meat is considered low value and therefore not worth the cost of transporting the bulky shark bodies to market. Any shark is taken-regardless of age, size, or species. Longlines, used in shark finning operations, are the most significant cause of losses in shark populations worldwide. Shark finning is widespread, and largely unmanaged and unmonitored. Shark finning has increased over the past decade due to the increasing demand for shark fins (for shark fin soup and traditional cures), improved fishing technology, and improved market economics. Shark specialists estimate that 100 million sharks are killed for their fins, annually. One pound of dried shark fin can retail for $300 or more. It’s a multi-billion dollar industry. Impacts of Shark Finning Loss and devastation of shark populations around the world. Experts estimate that within a decade, most species of sharks will be lost because of longlining. Unsustainable fishery. The massive quantity of sharks harvested and lack of selection deplete shark populations faster than their...

...Captain Ahab who is determined to kill the whale or die trying. Now this is a work of fiction but people have been hunting whales for tens of thousands of years. It only took America about ten years to kill 50 – 60 million buffalo; it makes it hard to believe there are many whales left after thousands of years hunting them. This paper is about the Whaling Debate on whether countries should be allowed to continue to hunt whales or should we leave them protected and my beliefs on the subject. This debate has also focused on issues of sustainability and conservation as well as ownership and national sovereignty. Some of the issues included in these debates is the question of cetacean intelligence this refers to the Cetacea order of mammals, which includes whales, porpoises, and dolphins; and the level of suffering which the animals undergo when caught and killed (The Whale Debate: Whale Wars, 2014). Another hot topic in the debate right now is the right to kill a certain amount of whales for scientific research, Japan kills 1000 minke whales a year and about 100 endangered fin and humpback whales. Whales are mammals the same as we are and they are intelligent and have feelings such as pain and a sense of loss. Before I get into my opinion I will list the pros and cons of this particular activity. There are a few of each so I will start with the reasons for whaling, many indigenous people, such as the Inuit’s of Alaska, rely on whales for food and other materials to survive...

...David Stauth and Stuart WolpertJuly 01, 2010Category: Research Illustration of sabertooth cat fighting with woolly mammoth. (Credit: Mauricio Anton, courtesy of Oregon State University) The extinction of woolly mammoths and other large mammals more than 10,000 years ago may be explained by the same type of cascade of ecosystem disruption that is being caused today by the global decline of predators such as wolves, cougars and sharks, life scientists report July 1 in the cover article of the journal Bioscience. Then, as now, the cascading events were originally begun by human disruption of ecosystems, a new study concludes, but around 15,000 years ago the problem was not the loss of a key predator, but the addition of one — human hunters with spears. This mass extinction was caused by newly arrived humans tipping the balance of power and competing with major predators such as sabertooth cats, the authors of the new analysis argue. An equilibrium that had survived for thousands of years was disrupted, perhaps explaining the loss of two-thirds of North America's large mammals during this period. "We suggest that the arrival of humans to North America triggered a trophic cascade in which competition for the largest prey was intensified, ultimately causing the large non-human carnivores to decimate the large herbivores," said Blaire Van Valkenburgh, UCLA professor of ecology and evolutionary biology and a co-author on the paper. "When human hunters arrived on the scene, they provided...

...Plankton Depletion and Environmental Effects Plankton is a term generally used for microorganisms or “floaters” that simply drift along wherever water currents take them. This includes zooplankton, algae, phytoplankton, and bacteria (G. Karleskint Jr. et al, 2010, p.464). But while it is common to see them as food for fish, they have other roles in nature what make them essential organisms in the delicate balance of our ecosystem. This paper will highlight the critical role of plankton as the organisms that make life on earth possible by describing the foundational role it plays in the food chain and in significant bio-chemical processes and discussing the negative effects it will give to the environment. I. Main Functions of Plankton in the Environment There are two main roles played by plankton in the environment. The first important role of plankton is in the food chain. Because of their microscopic size, they serve as food for other microorganisms, fishes and seal animals, which make-up 30% percent of the world’s entire intake of animal protein (J.H. Steele et al, 2009, p.8). Thus, we find plankton at the bottom of the food chain: zooplanktons eat other planktons for food, which in turn, along with phytoplankton and bacterioplankton, are food for fish and sea mammals, most of which eventually become food for human beings. Secondly, plankton plays an important role in the earth’s biochemical processes. Phytoplankton, for one, is responsible for the primary production...

...Resources and Energy Paper People, Science, and the Environment SCI 256 “Earth provides enough to satisfy every man’s need, but not every man’s greed.” (Gandhi, 2011) Did Gandhi have foresight into the destructive ways of humans? Earth seemed to have endless amenities that would take humans a lifetime to consume. With the abundance of these amenities, have humans failed to conserve and nurture nature’s gifts in the name of greed? In this paper, the subject to identify and discuss will be the effects that a growing human population may have on the marine ecosystem’s resources, including loss or harm to population of wild species; discuss one management practice of sustainability and conservation of natural resources in the marine ecosystem. Finally, the paper will identify is the risks and benefits of extracting or using one type of nonrenewable and one type of renewable energy resource from the marine ecosystem. From a distance in space humans look at this planet called Earth. Earth covers the massive blue oceans of life. Planet Earth humans call home consist of numerous types of land and marine species from the deepest part of the ocean to the clear shallow water of sandy beaches that lie within an ecosystem. The marine ecosystem is so complex but at the same time it is not complicated. Humans cannot see creatures with the naked eye but can spot a massive blue whale from a distance; this...

...Organism Physiology Organism Physiology BIO/ 101 Nov. 30, 2012 University of Phoenix Organism Physiology My paper is going to discuss organism physiology and the basic fundamentals of organism while explaining what my understanding is and what I have learned. In order to better help me understand what organism is I had to first define the meaning. “Organisms are any living thing such as fungus, animals, plants, or micro-organism” (Dictionary.com) in which is a body made up of organs, organelles, along with different other parts that combine together to help continue the process of life. The continuous organisms never stop only cause it is what living things need to live for example the life of a dolphin. Dolphins have been known to be social creatures also being known for their interaction for the purpose of hunting, defense, and reproduction. (Aqua)They are also carnivores that feed on such sea creatures as fish, squid, octopus, cuttlefish, crabs, shrimps, and lobsters as for them; they are mostly food for sharks, killer whales, humans. Most expected age for an normal living Dolphins is said to be around the age of 30 years. Compare to a normal human that’s usually consider a young age. (UnderstandDolphins.com- (Diagram) In looking at the diagram, you see a lot of common factors that most living things have in order to live such as a heart, a brain, bones, and other organs that a body would need to live. As the same as human being animals have certain and...

...“What’s the difference between creationism and evolution?” Charles Darwin’s work on evolution is the most recognized throughout history and the evidence that he discovered supporting evolution changed how many people viewed the history of our universe. His main research project was on a process called natural selection, the idea that survival of the fittest has been a main determinant is shaping how the earth and all living things appear today. Charles Darwin discuses this idea of Natural Selection in his essay “Natural Selection”, detailing evidence supporting his theory. This paper will discuss Darwin’s essay but will also go into further detail of his discoveries, other evolutionary milestones and finally comparing and contrasting the evolutionary argument to the creationism point of view. The idea of evolution first came about in the 1600’s when European naturalists started to question the current theories about how our universe was created. In 1666 the first evidence of evolution was discovered when a couple of fishermen caught a shark. On inspection they noticed that the shark’s teeth resembled “tongue stones”, thought to be triangular shaped rocks but actually fossils that came from the mouths of once-living sharks. The next major revelation came in the 1700’s when George-Louis Buffon became the first scientist to not rely on religious points of view when discussing how the earth was created. Instead...

In this document you will obtain a brief explanation of nuclear waste, plastic, coal and oil. What are the alternatives of other energy resources, advantages and disadvantages that would contribute to stabilize the environment currently around the the surrounding areas. Effects: Plastic is one of the most used resources that society has; the most common are plastic bags and beverage bottles. Plastic though durable is very slow to degrade. Plastic is sourced from two major categories, thermoset and thermoplastics; thermoset means that the plastic solidifies when it’s heated. Thermoset plastics are most commonly used in cars and construction; soften when heated however they resume their original composition when at room temperature. Some common thermoplastic products include milk jugs, credit cards and carpet fibers. Plastic makes up 13% of solid waste in our water system ; shockingly 8% of plastic is recycled. Plastic in our soil can block the flow of water through the soil as well as hinder the growth production. Plastic covers about 40% of our world’s ocean surfaces. The greatest affect of all is the effect on our...

...TRACING THE ORIGIN OF THE CHARACTERISTIC BAD ODOUR OF DRIED STOCK FISH PROJECT BY ADESINA ADEBOWALE T. (2011) 1.0 INTRODUCTION 1.1 Background Information With the ever growing population and the need to store and transport food from one place to another where it is needed, food preservation becomes necessary in order to increase its shelf life and maintain its nutritional value, texture and flavor. Therefore good food preservation techniques must prevent microbial spoilage of food without affecting its quality and nutritional attributes. Fish are recognized as highly perishable having a relatively short shelf life, therefore fish requires proper handling and preservation to increase its shelf life and retain its quality and nutritional attributes. Fresh fish spoilage can be very rapid after it is caught, immediately a fish is caught it loses its natural resistance to attack by microorganism and also start to undergo both physical and chemical changes that in return bring changes in appearance, taste, smell and texture. During fish spoilage there is a breakdown of various components and formation of new compounds. This new compounds are responsible for changes in odour, flavour and texture of the fish. Fish lipids contain omega − 3 polyunsaturated fatty acid (PUFA), especially Eicosapentaenoic acid (EPA) and Docosahexaenoic acid (DHA). These fatty acids play a vital role in human nutrition, disease prevention, and health promotion. Long chain omega − 3 PUFAs cannot be synthesized...
