On the other hand the professor opposes this by saying that all the evident revealed that this declined had been happened because of the predation hypothesis, and refutes each of the author`s reasons.

Exxon Valdez and Tylenol Reflection Paper

...Prince William Sound. This incident put Exxon into a crisis as it made the Alaskan region into a worldwide symbol of environmental chaos. The enormity of the ecological ruin and the phenomenal task of cleanup caught the attention of the many nations. Many workers and volunteers flooded the area for its restoration which required extensive labor and $2.1 billion of Exxon funding. The crisis is blamed to the following reasons: the faults were Exxon’s inadequate equipments on the ship and the insufficient number of trained members. Another thing is that a crew was unable to maneuver the ship properly due to exhaustion with work aboard. It was also traced that Captain Joseph Hazelwood was under the influence of alcohol which was the reason why he cannot give proper instructions to the staff. Hazelwood's activities in town and on the ship are the main focuses of the investigation. This also became the basis of widespread media sensation. Indeed, Exxon’s reputation suffered severely. Some Public Relation Practitioners said that Exxon seriously worsened the damage to the public due to its slow and insufficient responses. Exxon also failed to establish itself as a company concerned about the problems it had caused. As a matter of fact Lawrence Rawl, Exxon’s chairman waited about a week before commenting on the crisis and almost three weeks before visiting the location of the spill. B.

Our Stolen Future

...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 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...

Instead, the expansion of agriculture and a steady decrease in the number of male farmworkers combined to cause the industry to hire more women in the postwar years...

...ton1.1 Major Themes of Environmental Science The study of environmental problems and their solutions has never been more important. Modern society in 2009 is hooked on oil. Production has declined, while demand has grown, and the population of the world has been increasing by more than 70 million each year. The emerging energy crisis is producing an economic crisis, as the prices of everything produced from oil (fertilizer, food, and fuel) rise beyond what some people can afford to pay. Energy and economic problems come at a time of unprecedented environmental concerns, from the local to global level. At the beginning of the modern era—in A.D. 1—the number of people in the world was probably about 100 million, one-third of the present population of the United States. In 1960 the world contained 3 billion people. Our population has more than doubled in the last 40 years, to 6.8 billion people today. In the United States, population increase is often apparent when we travel. Urban traffic snarls, long lines to enter national parks, and difficulty getting tickets to popular attractions are all symptoms of a growing population. If recent human population growth rates continue, our numbers could reach 9.4 billion by 2050. The problem is that the Earth has not grown any larger, and the abundance of its resources has not increased—in many cases, quite the opposite. How, then, can Earth sustain all these people? And what is the maximum number of people that could live on Earth, not just...

The Everglades Flood Control and Restoration: a Century of Disaster

...March 2, 2013 – The Everglades Flood Control and Restoration: A Century of Disaster OUTLINE ABSTRACT ……………………………………………………………………………………………… Before drainage of the Everglades began over a century ago, the wetlands of southern Florida were an interconnected hydrological assortment of lavish freshwater lakes and streams, cypress swamps, secluded estuarine lagoons, freshwater sloughs, tree islands, wet prairies, and mangrove swamps spanning 3.6 million hectares. After a century of intrusion, the daunting task of understanding, fixing, maintaining, and regaining a sustainable, natural Everglades-type ecosystem in South Florida is monumental. The area south of Lake Okeechobee now has a human population of over four million people, with greedy agricultural and urban demands for more water and more space. Therefore, several uphill battles have ensued. The conceptual plans for restoring this ecosystem, currently on record, are all extremely expensive to implement. A more thorough definition of the environmental and societal objectives and measures of success are required. How the ecosystem will respond to the return of a more natural hydrological pattern is uncertain, but needs to be addressed as the expected and desired outcome through measures of performance. The critical level of deterioration of the Everglades has created a crisis-management atmosphere instead of a full spectrum response and future prevention methodology. The political and social aspects of the Everglades...

Collapse

...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...

CHAPTER I IN WHICH PHILEAS FOGG AND PASSEPARTOUT ACCEPT EACH OTHER, THE ONE AS MASTER, THE OTHER AS MAN M r. Phileas Fogg lived, in 1872, at No. 7, Saville Row, Burlington Gardens, the house in which Sheridan died in 1814. He was one of the most noticeable members of the Reform Club, though he seemed always to avoid attracting attention; an enigmatical personage, about whom little was known, except that he was a polished man of the world. People said that he resembled Byron—at least that his head was Byronic; but he was a bearded, tranquil Byron, who might live on a thousand years without growing old. Certainly an Englishman, it was more doubtful whether Phileas Fogg was a Londoner. He was never seen on ‘Change, nor at the Bank, nor in the counting-rooms of the  Around the World in 80 Days ‘City”; no ships ever came into London docks of which he was the owner; he had no public employment; he had never been entered at any of the Inns of Court, either at the Temple, or Lincoln’s Inn, or Gray’s Inn; nor had his voice ever resounded in the Court of Chancery, or in the Exchequer, or the Queen’s Bench, or the Ecclesiastical Courts. He certainly was not a manufacturer; nor was he a merchant or a gentleman farmer. His name was strange to the scientific and learned societies...
