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 …show more content…
As evidenced by their name, the range of Atlantic Bluefin tuna spans the Atlantic Ocean, concentrating mainly in the North Atlantic. In the 2014-2015 International Commission for the Conservation of Atlantic Tunas (ICCAT) report, it says that the species spawns in two main areas in the Gulf of Mexico and the Mediterranean Sea (Porch and Sylavain 92). The IUCN Red List describes this species as “a pelagic, oceanodromous species, that seasonally can be found close to shore and can tolerate a wide range of temperatures” (Collette et al. 1). According to FishWatch by the National Oceanic and Atmospheric Administration (NOAA), “Atlantic bluefin tuna live near the surface in temperate waters but frequently dive to depths of 500 to 1,000 meters. They are the largest of the tuna species and can reach up to 13 feet and 2,000 pounds. Atlantic bluefin tuna have large, torpedo-shaped bodies that are nearly circular in cross-section” (1). This streamlined shape allows them to reach speeds of up to 40 miles per hour, allowing them to evade predators and to chase down their prey. The culmination of their size and speed results in Atlantic Bluefin tuna claiming the title of a top predator in its ecosystem. Adults

...Natural 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.

Our Stolen Future

...Name: C.T.B. Assignment: “Our Stolen Future” Date: 12/03/2012 The Book “Our Stolen Future” is considered to be a sequel of “Silent Spring“, a Rachel’s Carson classic work, a clarion call to protect the American public from manmade synthetic pesticides that cause genetic mutations and cancer. Carson not only described how persistent chemicals were contaminating the natural world, she documented how those chemicals where accumulated into our bodies. Since then, studies of human breast milk and body fat have confirmed the extent of our exposure. Human beings in such remote locations as Canada’s far northern Baffin Island now carry traces of persistent chemicals in their bodies, including notorious compounds as PCBs, DDT and dioxin. Even worse, in the womb and through breast milk, mothers pass this chemical legacy on to the next 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 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).

...文勇的新托福精选阅读(原黄金29篇)真题[2010年4月3日 5.8版本] 俺常常收到同学们的邮件,要我推荐各种各样阅读材料,问我iBT的复习资料中 Barron, Longman, Delta等等哪个更好。我其实很无奈---因为尽管这些机构很大牌,但大牌丝毫都不意味着文章“质量高”(比如你可以想想三鹿奶粉)---说这些机构的文章质量不高,并不是说文字写得不好,而是说这些文章的句子结构, 论述方式, 出题思路与ETS的并不一致(有时候甚至大相径庭):用这样的材料训练,实在是 事倍功半。 于是,我们实在应该去找找由ETS出的iBT文章来做:(我们能够找到的|由ETS编纂的标准iBT文章有) 1. OG[1]之中的13篇文章[2];(其中3篇为第三版OG之中的文章) 2. 13次(套)TPO[3]之中的3*13=39篇文章[4]; 3. 早期[5]报名之时ETS赠送的3篇在线测试题 4. ETS官方给出的模考软件之中抽出的1篇文章; 于是这个文档在我的一时兴起之下,出现了: OG拿在手上,可以一个个字的敲成电子版;TPO的所有考试都是在自己的计算机进行,于是可以一边花钱参加考试,一边截图与录像---再利用截下来的图片,逐个的敲下来;早期的ETS赠送的3篇在线测试题,我也恰好有电子版本;官方的模考软件稍微用点功夫,就能将文章提取并复制出来。虽然工作有些繁杂,但总算完成了所有文章的敲打工作。再花了些时间,把这53篇文章都做了答案,附在文章的后面。(由于TPO之中有3篇文章与OG中完全重复,于是减去3篇,只剩下53篇。)同时我还更正了OG上几个明显的错误(详见文后附录)当然,我还做出了方便大家理解文章的参考译文,附在文章的后面。 在这53篇由ETS出的文章没有做完之前,我们实在不应该花时间在任何其他的题目之上。我有时候甚至会对着我的弟兄们高呼:“没有把这53篇做3遍,你好意思上考场么?你好意思花钱在任何一本垃圾书上面么?[6]” 另外,如果你正在准备iBT-SAT-GRE的作文部分或者写留学文书,也应该仔细的琢磨一下这些文章:经过ETS打磨的文章,无一不是精妙绝伦,极具模仿价值。常常有同学拜托我帮她(他)写PS,也说起自己的句子怎么看都像是小学生写的(尽管用上了GRE里面的单词),于是会随口问我“勇哥,您的写作能力是怎么训练出来的。”我说,“看呗,看呗:托福文章看多了,写作能力自然就提高了。” “这ETS的这些文章真的那么好?”。每当听到这个问题,我都会装做赵本山的样子来一句“谁用谁知道~~” 文勇 欢迎进行未删节的转载|且不必告诉我你转载到哪里去|都是一个战壕里面的弟兄啊… 告诉大家一个好消息,本文档中的TPO1-TPO9,以及在线测试题和官方模考题目的解析已经在市面上可以买到了!(好吧,我承认以下显然是广告部分): 这本《托福真题详解-阅读分卷-第一册》是给弟兄们现在市面上可以获得的TPO1-TPO9阅读部分的文章解析,题目解析,中文翻译和每篇文章的必备词汇:文章解析是为了让大家养成从整体抓文章结构的感觉,题目解析是为了使大家能够在做完题之后知道正确选项为什么对,错误选项为什么错——并且因此来培养良好的做题思路,中文翻译是为了帮助大家扫除那些自以为理解对但实际理解有误的句子,在每篇文章后面配上必备词汇无非是为了节省大家的一些查单词而已。 另外,这本书还包含了一张CD(我想你可能第一次听说阅读书...

Bad Bug Book

...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...
