Ecosystems are a system involving the interactions between a community of living organisms in a particular area and its nonliving environment. In the tropical forest there are many living and nonliving organisms that interactive for the daily growth and life in the forest. Tropical forest’s cover about seven percent’s of the earth and contains approximately fifty percent of the worlds’ species. Tropical rain forest is and interesting ecosystem, it contains different and a wide variety of species. All the species interact with one another to help sustain way of life. The major functions of the rain forest is they help stabilize the world’s climate, provide home to many plants, animals, and even people, and protect against floods, droughts, or erosions. Tropical rain forests have a characteristic structure that is made up of a number of vertical layers that reach up from the forest floor to the very tops of the tallest trees (Unknown). The major layers of the rain forest are the ground, canopy, understory, and overstory level. Each level have their own plant and species that may live t...
Wal-Mart, a "Big-Box Retailer" employs more than 2.1 million associates worldwide and has two-thousand seven-hundred stores in the United States with many more in Argentina, Brazil, Canada, Central America, Chile, China, Germany, Japan, Korea, India, Mexico, Puerto Rico, and the United Kingdom, making Wal-Mart the largest retailer in the world. "Wal-Mart accounts for upward of 30 percent of U.S. sales, and plans to more than double its sales within the next five years" (Lynn 29-36). Why is Wal-Mart so successful, and is Wal-Mart actually bad for America?
In 1962, Wal-Mart opened their first store in Rogers, Arkansas. In 1970, Wal-Mart's first distribution center and home office in Bentonville, Ark. open and Wal-Mart went public on the New York Stock Exchange. Just nine years from that, Wal-Mart's annual sales exceeded one billion dollars. In 1988, Wal-Mart super centers opened across the country. In a merely three years from that, Wal-Mart opened their own store in Mexico City, Mexico; making Wal-Mart an international corporation. Not even sixty years has past, and yet, Wal-Mart is over-powering our country.
Wal-Mart represents the sickness of capitalism at its almost fully evolved state. As Jim Hightower said, "Why single out Wal-Mart? Because it's a hog. Despite the homespun image it cultivates in its ads, it operates with an arrogance and avarice that would make Enron blush and John D. Rockefeller envious. It's the world's biggest retail corporation and America's largest private employer; Sam Robson Walton, a member of the ruling family, is one of the richest people on earth. Wal-Mart and the Waltons got to the top the old-fashioned way: by roughing people up. Their low, low prices are the product of two ruthless commandments: Extract the last penny possible from human toil and squeeze the last dime from its thousands of suppliers, who are left with no profit margin unless they adopt the Wal-Mart model of using nonunion labor and shipping production to low-wage hellholes abroad." (The Nation, March 4th 2002 www.thenation.com/doc.mhtml?i=20020304&s=hightower).
a) The Daintree rainforest at Cape Tribulation, in far north Queensland is diverse in many ways. It holds 12 of the 19 primitive plant families in the world (Cairns Today, 2007). The forest covers an area of 1100 square kilometres and is approximately eighty kilometres wide. This dense and luxuriant rainforest has the greatest diversity than any other in Australia and many in the world. The Daintree is also the home of rare and threatened of being extinct plant and animal species. The importance of this ecosystem is the very high. This ecosystem contributes to the overall health of this plant in many ways. The diversity contributes in the breakdown of pollution and helps to control the climate to name a few. This rainforest also is a great ‘carbon sink’. It has many photosynthesising plants and this allows the control of carbon dioxide (CO2). The plants take in the CO2 from the atmosphere and return oxygen (O2)
Wal-Mart has had a significant economic impact on the US, as well as the economies of countries that have relations with the US. Wal-Mart is the world’s biggest company of any kind, with 80 percent of the households in America purchasing something from the superstore; it is the nation’s largest retailer. Wal-Mart’s continuing price reduction has given Americans the advantage of being able to afford 15 to 20 percent more than they previously could. (Hansen) In a world governed by globalization and greed, competition has become rigid; as a result firms like Wal-Mart have utilized advanced marketing strategies to insure that they are on the ‘neck’ of competition, and are the core deciders of the market. (Ortega) However, Wal-Mart made decisions that were of a disadvantage to aspects of the economy, including the depletion on a small scale of Small Town USA.
With its headquarters in Bentonville, Arkansas, Wal-Mart was commissioned in the hands of its founder Sam Walton. Generally, the Wal-Mart effect is structured in a manner that it aids economic experts to evaluate attached global and local economic effects to the famous Wal-Mart retail. The term Wal-Mart effect is often employed by analysts to refer to the wide variety of both negative and positive influences of the retail business (Hiltzik 1). Evaluation of the retail’s effects is significant as the business is not only a key figure is the world’s economy but also it is arguably the most performing private economic retail. Briefly, Wal-Mart has conventionally caught the eyes of consumers since it not only boosts their experience by suburbanizing local shopping but also it avails low commodity prices for necessities (Neumark, Junfu, and Stephen 406).
Wal-Mart has been a huge debate subject in the news since it began to pop up in large quantities across the entire United States. The majority of that conversation focused on the negative impacts that Wal-Mart has on the communities and economies in which its super stores are located. Richard Vedder and Wendell Cox take a different approach and while they recognizes the downfalls and negative impacts that Wal-Mart can have, he focuses more on proving that the positives that Wal-Mart has on economies and communities outweigh those negatives.
Wal-Mart’s competitive environment is quite unique. Although Wal-Mart’s primary competition comes from general merchandise retailers, warehouse clubs and supermarket retailers also present competitive pressure. The discount retail industry is substantial in size and is constantly experiencing growth and change. The top competitors compete both nationally and internationally. There is extensive competition on pricing, location, store size, layout and environment, merchandise mix, technology and innovation, and overall image. The market is definitely characterized by economies of scale. Top retailers vertically integrate many functions, such as purchasing, manufacturing, advertising, and shipping. Large scale functions such as these give the top competitors a significant cost advantage over small-scale competition.
Tropical rainforests are an extremely unique and diverse ecosystem that are located around the earth’s equator. They once covered roughly 7% of the world, but due to human encroachment that has dwindled to just 2%. It is a highly moisture rich environment that typically receives anywhere between 60 and 400 inches of rainfall annually and average humidity ranges from 70 to 90%. A high average year round temperature, coupled with the moisture rich environment, creates an ecosystem that allows for a level of biodiversity seen nowhere else on the planet. This also results in a specific type of layering design that allows the system to survive and recycle its nutrients.
Wal-Mart's history is one of innovation, leadership and success. It started with a single store in Rogers, Arkansas in 1962 and has grown to what is now the world's largest - and arguably, the most emulated - retailer. Some researchers refer to Wal-Mart as the industry trendsetter. Today, this retailing pioneer has annual revenues of over $100 billion, 3,000 stores and more than 750,000 employees worldwide. Wal-Mart operates each store, from the products it stocks, to the front-end equipment that helps speed checkout, with the same philosophy: provide everyday low prices and superior customer service. Lower prices also eliminate the expense of frequent sales promotions and sales are more predictable. Wal-Mart has invested heavily in its unique cross-docking inventory system. Cross docking has enabled Wal-Mart to achieve economies of scale which reduce its costs of sales. With this system, goods are continuously delivered to stores within 48 hours and often without having to inventory them. This allows Wal-Mart to replenish the shelves 4 times faster than its competition. Wal-Mart’s ability to replenish theirs shelves four times faster than its competition is just another advantage they have over competition. Wal-Mart leverages its buying power through purchasing in bulks and distributing the goods on it’s own. Wal-Mart guarantees everyday low prices and considers them the one stop shop.
This article is going to tackle the history of one of the largest multinational retailer with more than 8500 stores all over the world, “Walmart”. Walmart now employs more than 2.1 million people, and more than 200 million customers visit their stores every week.
Walmart is the world’s largest retailer. Its revenue was considered as GDP it would be 23 countries ahead of Sweden. Walmart has 4 different segments Walmart stores, Sam’s club, international, and other private labels. Walmart has great strengths like efficient supply chain cross docking and inventory management, service innovation, strong penetration and is the world’s largest private satellite communication system. With every company they also have weakness like poor public image, unable to adapt internationally and strict labor laws. Walmart have come across some great opportunities over the years. They have opportunities like globalization in the middle class globally, e-business and inorganic growth leading to consolidation. They have also encounter some threats
The Human Impact on Rainforests Human Impact on Rainforest is it a necessity? Rainforest are the beautiful gift of Mother Nature. It consists of the most magnificent species and plants in the world. 4.2% of the world’s animals live in the rainforest. This statistic it self shows how bad it would be to destroy such essential part of the worlds biodiversity.
Rainforests once covered 14% of the worlds land surface, however now it only covers a mere 6%. It is estimated that all rainforests could be consumed in less than 40 years. Trees are becoming more needed and used everyday. We need them cut down for many reasons such as paper and timber, while also needing them ‘untouched’ for other reasons like oxygen, we have to ask ourselves, which is more important? At the current rate, most of the rainforests are being cut down for resources like paper and timber, but less importance is being placed on main resources like oxygen.
The branch of science that deals with how living things, including humans, are related to their surroundings is called ecology . The Earth supports some 5 million species of plants, animals, and microorganisms. These interact and influence their surroundings, forming a vast network of interrelated environmental systems called ecosystems. The arctic tundra is an ecosystem and so is a Brazilian rain forest. The islands of Hawaii are a relatively isolated ecosystem. If left undisturbed, natural environmental systems tend to achieve balance or stability among the various species of plants and animals. Complex ecosystems are able to compensate for changes caused by weather or intrusions from migrating animals and are therefore usually said to be more stable than simple ecosystems. A field of corn has only one dominant species, the corn plant, and is a very simple ecosystem. It is easily destroyed by drought, insects, disease, or overuse. A forest may remain relatively unchanged by weather that would destroy a nearby field of corn, because the forest is characterized by greater diversity of plants and animals. Its complexity gives it stability.
