Acid Rain: Scourge from the Skies

North Americans have been smelting ore and burning fossil fuels for generations. In the past, the gases went up ordinary chimneys or small smoke stacks, to descend upon near by areas and pollute them, states author, Robert Collins. Almost everyone knows what acid rain is and has a vague idea of the consequences that exist as a cause of it. Most people however do not realize the severity of acid rain. The essay Acid Rain: Scourge from the Skies by Robert Collins was very effective in showing the…

An Analysis of the Environmental Issue of the Destruction of the Rainforests

The destruction of the rainforests is one of the most crucial environmental issues of our time. It is also one of the most misunderstood and neglected. There has been so much propaganda and publicity attached to this crisis that Save the Rainforests is becoming almost as clich as Save the Whales. Why dont we take this problem more seriously? Is it because we, as Americans, simply dont understand the devastating, long-terms consequences that continued deforestation of the rainforests would have?…


An Argument in Favor of Imposing Tax on Plastic Bags

As more research comes in, resource sustainability and the effects of our daily carbon footprint have come more and more to the forefront of Americans' consciousness. Given the terrible environmental consequences of both single-use plastic and paper bags, the most socially responsible action for communities to adopt would be to tax all single use bags, as the tax would serve as a deterrent to consumers, thus saving the environment, the tax revenue can be funneled back into much needed resea…


An Argument in Favor of Ecology in regards to Technology

QUESTION 1: Technology owes Ecology an Apology. Indeed, in my opinion, technology does owe ecology an apology. This is because ecological imbalances were as a result of the Industrial revolution, which could be said to be the beginning of the non-ending technological advancement cycle. During Industrial revolution, we began altering or climate and environment through changing agricultural and industrial practices.  Before the industrial revolution, human activity released very few gases…

The world powers of the 20th century are dealing with issues such as an aging population, while non-Western countries are on the rise. The population has steadily continued to grow. Regardless of where countries are in their respective timelines, there is one shared issue that Earth must cooperate to begin to tackle: the ecological wellbeing of our planet, which is currently in a poor state. In order to responsibly in…


An Analysis of Tropical Rain Forests and the Many Issues of Ecology

Tropical Rain Forests: Physical Factors, Politics and Possible Soltutions Every year 11 million hectares of tropical rain forest are lost through commercial and subsidence pressures ( Winterbottom and Hazelwood, 1987). The pressures that cause forest clearance varies geographically. In Amazonia the primary force is to clear cut the forest for agriculture (Goodland, 1982). The most common usage of this cleared land is for the production of coffee, cocoa, rice and for cattle ranching (Goodland…


Saving and Protecting the Fauna through Conservation Projects from Overexploitation Which Leads to Extinction

Who Cares? It's Just an Animal: The Importance of Saving Our Fauna Pizza is the saddest polar bear in the world. Pizza is confined in a tiny aquarium located at Grandview Mall in Guangzhou, China. His only interaction is with the flashing lights and obsessive eyes of tourists. His walls are painted with a dark shade of blue in an attempt to make his small cage look like his real home, the Arctic. Pizza does not know what sunlight or fresh air feels like. Unfortunately, being in such solitu…


Topic of the Various Theories in Management and the Population Ecology

Various theories in management take the view that organisations are in a constant struggle with the environment. This essay will examine three theories in seeking to determine whether this widely held view is demonstrated in these theories. It will examine population ecology theory, systems theory, and contingency theory, firstly defining what each is and then second relating the various theories to the environment. Population ecology takes the view that the environment is dominant, and orga…

Topic of the Issues of Pollution in the America

Polluting America Do you ever wonder what you are inhaling into your lungs? Are you concerned? When you drive past large chemical plants, do you see the large amounts of smoke continuously being released into the air? Did you realize that the pollution released is probably more than legally released? Many people do not consider the danger we are in. We are breathing chemicals into our lungs that harm our bodies and organs. Many industrial plants release excess amounts of these pollutants, an…


An Analysis of The Threat to Soil Biodiversity and Quality

It is well known that soil is an extremely important aspect in any ecosystem. It provides the nutrients for any land based fauna to develop and thus is at the start and end of the food chain. However, like any aspect of the environment, there is the threat of pollution and degradation with human influence. According the he article, over 80% of all land is influenced by human interaction. Majority of the areas influenced are being degraded and being used at an alarming rate in which sustainab…


The Roadless Area Final Rule: Conservation or Preservation?

In 1978, the United States Forest Service (USFS) began the management of roadless areas, i.e., all areas greater than 5,000 acres and without constructed roads, in a study called Roadless Area Review and Evaluation II (RARE 11). The purpose of this study was to determine the suitability of these roadless areas for inclusion in the National Wilderness Preservation System. On October 13, 1999, twenty-one years later, President Clinton directed the Forest Service to provide long-term protection to…


An Analysis of the Relation between Acid Rains and the Decline in the Red Spruce Population in Vermont and Northeastern Forests

Acid Rain. It is a term that has been imbedded in us for many decades and yet still it is an issue today. It is a term that was coined in 1872 by Dr. Robert Angus Smith, an English chemist. (Mello 21). He noticed that the air in the cities contained many different contaminates including sulfuric acid, which he believed to be the cause of corroding metals and certain types of damage to plants. His colleagues ignored his studies and findings and it wasnt until 100 years later that scientists star…


An Analysis of the Reform in the Spirit of Conservation

Reform in the Spirit of Conservation The creation of the Civilian Conservation Corps and Civil Works Administration revolutionized the U.S. federal government by redefining its roles in the lives of its citizens. Prior to the Great Depression and Franklin D. Roosevelts resulting New Deal, the federal government had taken no responsibility in the employment or welfare of U.S. citizens. People were employed by privately owned businesses and the poor, if they received any help at all, were aide…


An Analysis of the Problem of the Destruction of the Rainforests

The destruction of the rainforests is happening at a great rate and must be stopped now. A delegate from U.S. Congress, Al Gore , says 1/ "The devastation of the rainforest is just unbelievable. It's one of the great tragedies of all history." Last year the smoke in Porto Velho, the capital of the Brazilian state of Rondonia, was so thick the airport had to be shut down. 2/ "An estimated 12,350 square miles of Brazilian rain forest an area larger than Belgium, was reduced to …

Grpundwater Contamination Groundwater is the largest source of freshwater. Groundwater is water contained in the pore spaces between oil and rocks below the Earths surface. The supply of Groundwater is larger than all the streams and lakes of the world combined. Groundwater pollution is a serious problem because many people depend on groundwater for their drinking water. Car pollution of soil and groundwater comes from various sources, such as runoff of used motor oil, improperly disposed ca…


A Personal View of Life's Meaning as an Ecological Being on the Planet Earth

The question that is before us is rather complex: What is my lifes meaning as an ecological being on the Planet Earth? In this essay, I will attempt to explore three aspects of my life, as they pertain to the environment and the ecological footprint that I have left, and while leave in the future. This will be achieved through exploring three important aspects of my life, as they relate to the environment: Consumption, Career, and Speaking Up. The first aspect I will explore of my life, as i…


An Analysis of Squirrel Behavior in Ecology

Abstract As our population expands and cities grow and spread out into the country, the line between wilderness and civilization becomes thinner and thinner. The relationship between animals and humans becomes more and more strained, and the understanding of animal behavior in the presence of man becomes increasingly important. A great example of a species that has successfully adapted to life with humans is the gray squirrel. My study tried to prove that squirrels learn to live with humans …


An Analysis of Psychological Ecology in The Power of Place

The Power of Place by Winifred Gallagher When people think of their environment people think of their immediate surroundings; however, one's environment goes beyond and further into the psychological connection to one's personal environment. To further explain, Gallagher discusses three different aspects of The Power of Place: Outside In, Inside Out, and Synchrony. The book opens doors previously unnoticed about psychological ecology. From reading the book one learns that settings in…

Question of Dakota Access Pipeline

The Dakota Access Pipeline (DAPL) has become the prime example of the classic big business vs environment conflict. The legalities of the matter are complicated as this particular pipeline deals with a special case, Native American grounds. The easier to understand phenomenon of this matter is the treatment of the protestors. The police brutality and excessive force inflicted on the peaceful protestors by the police is something the black community knows all too well. An injustice anywhere i…


Renewable Fuel Biofuels and the Issues of Pollution on our Ecosystem

Introduction Nowadays, industry is developing more than ever before and this has a major influence on pollution of our planet. The amount of gas that factories release into the air on a daily basis is enormous. Also, vehicles represent a big factor of pollution of cities ecosystem. For example, people who live in Beijing wear masks all day to try to reduce the amount of pollution that gets into their organism. This should create a big concern for what can happen in ten, twenty, or …


Human Population Growth and Ecosystem Impacts

The Florida Everglades is a complex ecosystem located in Southern Florida that is being hurt by human population growth. It is one of the largest wetlands in the world and used to be part of a watershed hundreds of years ago. The "historic Everglades” spanned more than 3,000,000 acres from Lake Okeechobee to Florida Bay. However, it started to shrink when settlers came in the early 1900's and used the Everglades' water for agricultural purposes and to use the land for houses.…


The Ecological Impact Of Lead Poisoning

Intro In the article, “The political ecology of lead poisoning in eastern North Carolina” (Hanchette, 2007) Hanchette studied the ecological impact of lead poisoning in eastern North Carolina and childhood blood lead levels. The elevated blood lead levels dropped from 88% to 2.2% from the late 1970s to 2000. But however, this is not the case in many eastern North Carolina counties. Testing Hanchette used LISA and Moran's I statistical analysis to spatially interpret the…


A Study on Landfills

Introduction Did you know? Americans use enough cardboard each year to make a bale as big as a football field and as high as the World Trade Center Towers. We even throw away so much aluminum every three months that we can rebuild our entire commercial air fleet. Each person, yes, included you, in America creates about 4.4 pounds of trash every single day. Did you also know? That it takes 100 years for tin to break down, 500 years for aluminum, and glass takes one million year…

A Research on Biodiversity Issue

Biodiversity is described by Ruth Patrick as, Ithe presence of a large number of species of animals and plants.l(Patrick 15). In other words, biodiversity is the term for the measure of the variety of different species that do exist still on our plant. These species can range from the simplest bacteria to the very complex primates. Biodiversity can relate locally or globally. For example the Southern New England forest contains 20 or 30 tree species while in the rainforest of Peru there are hun…


Animal and Plant Ecosystem Research

Introduction: Without ecosystems, how would living organisms prosper? The balance that is created in ecosystems between different communities, different population between species, competitions over materials, and more all fall under the umbrella of one specific topic: Ecology. Ecology is basically a category of Biology that studies the interactions and relationships between living/nonliving things and their surroundings. Everything starts when a producer absorbs sunlight from the sun. Th…


Impact of Uranium on Iraq

Part 1 Depleted uranium munitions are, in my opinion, almost impossible to defend. They're used to kill thousands in Iraq and other places every year. As if regular bullets aren't deadly enough, depleted uranium munitions release radiation as they hit their intended target, exploding and sending deadly radiation in a nearby radius. This radiation kills innocent people, not only soldiers. And there's the issue of friendly fire too; what about our own troops who get hit by these we…

Ozon Layer and a Growing Problem of Depletion

The Ozone Layer: What does it do and what happens when it is depleted? The ozone layer is one of the most debated scientific subjects of the last decade. The growing problem of its depletion is being researched heavily all over the world, and methods are being researched to try and solve the problem. There have also been many debates concerning the relationship between the ozone layer and the onset of global warming. Before solutions can be developed, however, what the ozone layer actually does…


Pluses and Minuses of Geoengineering

It is horrifying to think that with each passing day, we tumble closer to the end of the world. But even in a utopia, this fact would be true. Consequently, in our less-than-perfect world, there are many factors that speed up this process. Climate change, for example, has become a pressing issue that could result in dire consequences for both humanity and the Earth. Humans place the environment under constant stress, and considering that one year in relation to all time is the blink of an eye, …


A Research on Ecoagriculture Issue

Activity 1 Ecoagriculture describes the process of cultivating land that both supports the production of agriculture as well as promotes biodiversity. It is highly beneficial to rural communities as it can yield a good amount of agricultural products while still maintaining and even increasing the fruitfulness of the soil and plant life. In order for ecoagriculture to be implemented successfully, a high amount of biodiversity must be used. Biodiversity is the amount of variation of life form…


A Problem of Colony Collapse Disorder

Introduction Honey bees are so vital to the horticultural sector that any problem in their colonies would mean disaster to fruit, nut, seed and vegetable production. In Colony Collapse Disorder, also known as CCD, the worker bees in cultured bee colonies abruptly disappear, leaving combs that are full of honey. There was no appropriate name for this unexplained disappearance of adult worker bees; hence, the name "Colony Collapse Disorder" was crafted. To date, the cause of Colony C…


Research on Fish Population in the World's Ocean

Background info The population of fish in the world's oceans has greatly decreased in the last few decades, and is projected to completely collapse in 2048 if current rates continue. Over 25% of fish stocks are being overexploited, and 52% are being exploited to their fullest, with new boats coming on all the time. This means that if left unchecked, over 75% of fish stocks will be severely crippled and will possibly never recover. Marine biologist Stephen Palumbi from Stanford says that …


Best Practices of Supply Chain Management

Supply chain management is the integrated process-oriented planning and control of the flow of goods, information and money across the entire value and supply chain from the customer to the raw material supplier. Retail companies become involved in supply chain management to control product quality, inventory levels, timing, and expenses. In a global economy, supply chain management often includes dealings with companies and individual contributors in other countries, which requires involvement…


A Research on Water Biomes

Marshland is covered with grasses, reeds, sedges, and cattails. These plants all have their roots in soil covered or saturated with water and its leaves held above water.Marshes may be freshwater or salt. Freshwater marshes develop along the shallow edges of lakes and slow-moving rivers, forming when ponds and lakes become filled with sediment. Salt marshes occur on coastal tidal flats. Inland salt marshes occupy the edges of lakes. They affect the supply of nutrients, the movement of water, an…


A Research on the Common Forms of Ecological Fallacy

Throughout social research studies, various errors may occur and often such errors compromise the quality of research data, and this may lead to inaccurate research reports. One of the typical mistakes that can be frequently noticed in the social research procedures is the ecological fallacy, which occurs in the process of statistical data interpretation. The ecological fallacy arises when the deduction of the inferences on individual characteristics depends on the assumptions of the group…


A Research on Biodiversity

Due to the varieties of life forms, biological diversity is referred to as biodiversity. Biodiversity refers to the variation of forms of life within an environment. Biodiversity measures the health of various ecosystems (Campbell, 195). However, the main definitions of biodiversity are all centered along the varieties of all forms of life through the vast scope of ecosystems. The history of biodiversity is relatively very short, but the resultant effects are very important and distinctive. The…


A Report on the Preservation of the Wetlands of Bolsa Chica

The city of Bolsa Chica needs to take the next steps towards restoration of its precious wetlands. These steps should include the reconnection of the wetlands more directly to the ocean, the protection of existing wildlife, reestablishment of native animals and vegetation and the strict supervision of water quality. In order to protect the wetlands for the future generations, we must also educate the next generations about these valuable areas and how vital their survival is to the health of th…


A Report of Taiga the Largest Land Biome on Earth

The taiga is the largest land biome on earth, it covers some of Canada, Alaska, Europe, Asia, and most of Russia. The word "taiga" is Russian for the forest, but the word is used in the U.S. as well as Canada and some parts of Europe. The winters are cold, and the summers are wet and sometimes warm. The purpose of this paper is to describe the soil in the taiga. First of all, the soil is nutrient poor, thin, and acidic Podzolization occurs as a result of the acid soil solution prod…


A Problem of the Destruction of Coral Reefs

Not only do corals look like they should be called “ocean plants” but they have almost the same role except they are not plants. They are animals. Coral reefs play a large role in the sensitive ecosystem shared by both corals and fish. Recently coral reefs have been reduced in size and ultimately eliminated in parts of the world. A new project funded by Resorts World SuperFast has caused damage to the ecosystem on the island of Bimini along the Bahamas by destroying the coral r…


A Look at the Use of Herbicides in the United States

Each year in the United States of America over 69 percent of the available water is used for agriculture and 8 percent is used for domestic uses. Sewage, industrial waste and agricultural chemicals such as herbicides, pesticides, and fertilizers are the main point of water pollution. In the year of 1995 the EPA (Environmental Protection Agency) reported that 37 percent of our country's lakes and estuaries, and 36 percent of our country's rivers are too polluted for basic uses including …


A Look at the Gorilla and the Various Conservation Efforts to Save Them

Half man and half beast. This is what is usually said about the gorilla. They say that the gorilla is related to us. You can find mountain gorillas in the Virunga Volcanoes, which are located on the boundaries of Zaire, Rwanda, and Uganda. The Virungas are 600 miles of tropical rainforest. Youll find then roaming around 7,800 and 11,000 feet, but at low elevations. The gorillas live in units. Most of the units consist of about 6-12 members in it, most of them being related in some way. With eac…


A Look at the Amazonian Rainforest and Its Waters

In contrast to the scrublands that border it to the south, the Amazonian rainforest and the waters that drain it have a remarkable abundance of plant and animal life, even though the ecosystem is a fragile one that can easily be destroyed. While giving the impression of monotony because of the apparently similar tree crowns that rise to a more or less uniform height of around 150 to 200 feet, these lands contain the greatest variety of plant species on Earth--many thousands, less than half of w…


Greenpeace Organization Formed in 1971 for Environmental Protection

Greenpeace is an organization formed in 1971 initially to protest United States nuclear testing in Alaska for fear that it would cause an earthquake or a tsunami on the tectonically unstable Island of Amchitka. (Hunter, 2005: 35) On this original voyage, the intended goal of stopping the bomb from being detonated did not succeed, but within five months further testing was cancelled. The intended goal was not achieved, however the group did succeed in getting the attenti…


A Film Analysis of Waste Land

Waste Land is and extraordinary film that captured my attention the second I started watching. The story is based in Brazil at Jardim Gramacho in Rio de Janeiro a massive garbage dump.  The film begins with the famous artist Vik Muniz known for his extraordinary photographs that translates art from material. For example in this film he uses recycle items on the portraits of each person. Vik Muniz decided that he wanted the people to become the artist. He wanted them to be involved in build…


A Personal Explanation on the Ways the Oil Rig Working in the Desert Area

My father works at an oil company located in Abu Dhabi the capital of United Arab Emirates. He usually works on site at the Oil Rig; oil rig is a large structure with facilities to drill wells, to extract and process oil and natural gas. Sometimes when it's fixed to the ocean, it floats as an artificial island. The other possible location for an oil rig is in the midst of the wild desert. My father's work one that takes place in the wilderness and sometimes when am lucky he would take m…


A Discussion on the Issues of Large-Scale Production in Latin American Agriculture and the Methods to Solve Them

            The assumption that large-scale, industrial agriculture is necessary to ‘feed the world’ is greatly flawed. It has been seen throughout the world that this type of production does not only leave food insecurity unalleviated in areas/communities where it is most severe, but also does not contribute to the reduction of poverty in these places. This idea of feeding large amounts of people, which came about during the Gr…


A Discussion on the Growing Global Issue of Overpopulation

Out of the many growing problems on earth, environmental, political, and social, one of the most dangerous, rapidly growing, often ignored issues is overpopulation. The world has approximately 7 billion people living on it currently, and the population is still growing. It is estimated that in the year 2050 that number will reach 9 billion. A variety of serious problems stem from overpopulation, such as the depletion of natural resources, global warming, increased crime rate, and devastating po…


A Discussion on the Damage Affected by Large Scale Mines on the Environment and Scanning Electron Microscope (SEM), a Tool of Managing It

The last several decades have made at least one truth readily apparent to those who take the time to look at the evidence: extractive industries, such as the oil and mining sectors, have wreaked havoc on the environment all across the world. On top of this, it appears that much of this effect will continue into the future if current practices go unabated. With this in mind, this project proposal seeks to address the damage affected by large scale mines in a specific, practicable, and responsibl…


A Discussion on the Consequences of Coral Bleaching on Sessile Organisms

This publication discusses the consequences coral bleaching will have on sessile organisms. Sessile organisms like algae and coral are important for the complex makeup of the coral reefs and capture light and utilize gas to maintain primary production. The reefs are also the home of these sessile organisms as well. Coral bleaching will have major impacts on these organisms and in turn will have affect the reef biodiversity, growth and productivity. The publication dives into specific taxa that …

A Habitat Selection Under Predation Hazard in the Ecology

Ecological Scientists believe that some organisms may choose habitats or foraging sites based on both the net energy return to the organism and the mortality risk involved for the forager. The rate of foraging often decreases according to certain changes in their behavior. An example of these changes can be when the organisms shift habitats due to the presence of predators and also display behavioral changes from predator intimidation. Gilliam and Frasers study is based upon the organismal leve…


Career of an Ecologist

Because of the increasing changes in the environment, a career as an ecologist is an important venture, especially for an earth-science-oriented person with a love for nature and animals. With the number of ecological disasters escalating every year there is an ever increasing need for ecologists and people trained in ecology. Along with these disasters there are hundreds of animals and plants that are disappearing off the planet everyday. There is also an increasi…


The Destruction of Coral Reefs, the Largest Biological Structures on Earth, and the Need to Protect Them

Coral reefs are arguably the world's most beautiful habitats. Coral reefs have been called the rainforests of the oceans, because of the rich diversity of life they support. Scientists have not yet finished counting the thousands of different species of plants and animals that use or live in the coral reef. There are three types of coral reefs: fringing reefs, barrier reefs, and atolls. Fringing reefs are located close to shore, separated from land by only shallow water. Barrier reefs lie f…


A Description of the Effects of Tropical Climate of Africa to Its Citizens

Hunger is the result of disasters such as drought, floods, the changing of the jet stream patterns and other natural disasters. They are beyond our control. It has been estimated that one third of the land in Tropical Africa is potentially cultivable, though only about 6% of it is currently cultivated. However, to change farming from a low-input low yield pattern to a high-input, high-yield pattern necessitates the use of more fertilizer and the planting of high-yielding varieties of crops Ther…


A Definition of Ecosystem and the Factors Influencing Ecosystems

An ecosystem is a collection of all the organisms that live in a particular place, together  with their nonliving environment (Miller, 2003). A simple way it can defined is that it is a system containing a living community and a non living community (Kraus, 1999). All ecosystems have to include a source of energy, abiotic factors, biotic factors, a constant energy flow, material cycles, decomposers, and biodiversity. In a balanced ecosystem, a source of energy would would be sunlight. The …
