...GEO 215 Week 3 DQ 3 How will the deforestation of the Earth’s tropical forests affect the Earth’s temperature or climate? Explain. Response #1 Rainforest grows to large heights and it is important because a growth in the sunlight through the forest canopy can lead to species of the forest not surviving. with the forests getting direct sunlight and over 2 inches of rain an hour, the area is hot and humid. Deforestation is where less heat is absorbed and less moisture is released. The plant life that needs this warm, wet atmosphere will die with more sunlight and less moisture. Deforestation can be related to the growth of drought, flooding and releasing oxygen. Acres of the rainforest is being deforested globally and stored carbon is being released into the atmosphere. The rainforests play a hugh role in the local climate regulation because of the rainforests interaction with the water cycles. The rainforests have an enormous effect on global weather. Rainforests vegetation affect the surface albedo or the surface of the ground absorbing more heat than bare soil. The loss of the rainforest vegetative cover will mean there will be less heat absorption moving on to less moisture being taken up into the atmosphere. The deforested regions may decline the rainfall. Deforestation can affect weather in other parts of the world. There can be a change in the rainfall. The rainforest help generate rainfall over land masses. Response #2 Deforestation affects the climate by escalating...

...the 5 ice ages. Changes in our climate are indeed as old as our planet earth. However, global warming is one of the biggest issues of the twenty first century. Many researchers, scientists, and environmentalists are expressing concerns about changes on the climate on earth. Some believe that the climate is becoming abnormally warmer an issue which is referred as “global warming”. That’s why the major part of the world comes together to discuss about what are the causes and which impact they have on the life on earth. More and more countries are joining the meeting to discuss about how to define new restrictions to prevent and slow down the global warming. The surface of the earth which is warming up is not without consequences. Indeed some negative effects of the global warming have a heavy impact such as the rise in sea levels, less precipitation, expansion of the desert retreat of glaciers and sea ice. All these effects have their own consequences and there are many reasons which explain this global warming. Overpopulation, deforestation and burning of fossil fuels are listed as causes of the global warming. Fifty years ago the world population was about 3.7 billion with an emission of fossil fuels of 14 billion tons. Today the world population is 6.7 billion; nearly 7 billion with an emission of fossil fuels rise to 29 billion tons that is to say 107 percent more than in 1975. There are two negative effects related to the overpopulation. First, as long as the world population...

...Method: Topical Topic : Greenhouse Effect General purpose : To inform Specific purpose : To inform my audiences that the causes of greenhouse effect. Central idea : The causes of greenhouse effect are deforestation, burning of fossil, farm animals, fertilizer and electrical appliances. INTRODUCTION: I. If I ask you, what is greenhouse effect, what is the first thing across in your mind? II. The greenhouse effect is the warming of the Earth by trapped gas in the atmosphere. III. The gases present in the atmosphere refer to the term “greenhouse gases”. A. What are the greenhouse gases? B. How those gases bring to greenhouse effect? IV. However, there are several causes of the greenhouse effect. V. Today I will explain these causes to you. (Transition: We will start by looking at the deforestation.) BODY: I. Deforestation is one of the causes of greenhouse effect. A. Deforestation increases the amount of carbon dioxide in the atmosphere. 1. Photosynthesis cannot take place due to the disappearance of trees. B. Deforestation is also due to the burden of our needs on land. 1. With the increase in population, more and more forests are being cut to provide accommodation. C. Burning of forests for the purpose of deforestation will definitely increase the carbon dioxide. (Transition: We will move to the next causes of greenhouse effect.) II. Burning of fossil is another cause of greenhouse effect. A. Greenhouse gases can also be released...

...Global Warming Global warming is the greatest challenge facing our planet. It is, in fact, the increase in the temperature of the earth’s neon- surface air. It is one of the most current and widely discussed factors. It has far-reaching impact on biodiversity and climatic conditions of the planet. Several current trends clearly demonstrate that global warming is directly impacting on rising sea levels, the melting of ice caps and significant worldwide climate changes. But, what is causing the Global Warming? Can be the Global Warming stop or is too late? In short, global warming represents a fundamental threat to all living things on earth. The effects of global warming create a growing danger for the ecosystem we live in by damaging the environment as deforestation, contamination and something very simple as driving. It is a matter of time to see that we do not have a too much time because we are killing the earth with us inside. Firstly, one of the first causes of Global Warming that is being discussed is the ingress of the world population. The estimation of the world population is the seven billion people by The United States Census Bureau on March 12, 2012. Global average temperature rose significantly during the past century. The prevailing scientific view is that most of the temperature increases since mid-20th century has been caused by increases in atmospheric greenhouse gas concentrations produced by human activity. Most scientists agree that planet’s temperature has...

...Deforestation in the Amazon Discussion of the geographical, economical, and the overall influential importance of the Amazon Rainforest is, in my opinion, a necessity to understanding why deforestation is a huge mistake and will lead to major consequences for the entire planet. Common important facts about why deforestation of the Amazon Rainforest might include issues such as greenhouse gases or entire ecosystems demolished. Geographically, The Amazon Rainforest is by far the biggest rainforest left on our planet (sad to say) proportional to the size of Australia. The rainforest itself reaches out to several countries around Brazil. Economically, the regions of the Amazon Rainforest provide surrounding countries and entire continents with some of the most basic necessities and natural resources. Bananas, papayas, oranges, and pineapples are some of the major food exports out of the Amazon Rainforest regions. Along with food resources, many spices and other natural resources are only found in the Amazon Rainforest regions. Continuing the deforestation in order to use the land for other means of resources would harshly alter the economy of South America entirely and further affect the import/export economy of the United States and others. In addition to its economic influence, the Amazon Rainforest regions have aided advancements in medicine and scientific breakthroughs. Many explorations and scientific research of animal and plant life in the Amazon Rainforest...

...dioxide, methane, nitrous oxide, and ozone. The causes of increasing greenhouse gases are: Burning fossil fuels, thus releasing into the atmosphere carbon that has been safely stored for millions of years by burning coal, oil and natural gas for transport and electricity. An enormous demand for electricity. The growing population of the earth all want cars, refrigerators, air-conditioning and a double garage. Most electricity is generated by burning coal. A constant and growing demand for red meat. Cattle belch out methane, a toxic greenhouse gas, much more dangerous than carbon dioxide. More and more forests and bushland, which absorb carbon dioxide from the air, are being cut down so more cattle can graze. A reduction in the planet's ability to remove greenhouse gases from the atmosphere. The earth has natural sources of carbon dioxide (a greenhouse gas), and has had long before mankind began altering the environment, but the earth has natural means to actually remove some greenhouse gases from the atmosphere, especially carbon dioxide which is removed by plants (especially dense, tall forests) through photosynthesis. Global deforestation...

...Deforestation of the Amazonian Rainforest Tiffani Swank GE150 Survey of the Sciences Erica Price/Tuesday at 9:00 a.m. to 12:24 p.m. Earth’s natural resources are what we are extracting from the earth. Industries, which excavate the earth’s resources, include forestry, oil extraction, and mining. Present-day society is based upon a vast consumption of non-replaceable minerals and fuels such as coal, oil and natural gasses. Other materials such as cotton, wool timber and produce, if utilized wisely can be replenished. Is the carbon dioxide level higher, due to massive amounts of forest being cut down and the levels of carbon dioxide left in the atmosphere higher? Therefore, my hypothesis is that deforestation of the Amazon rainforest leads, not only, to a reduction of the amount of carbon dioxide taken out of the atmosphere, but also to an increased release of carbon dioxide in the atmosphere. The earth’s natural resources are there for all of us to use. We need the water, food, air, energy, medicines, warmth, shelter and minerals that the earth’s natural resources give us. Therefore, keeping us fed, comfortable, healthy and alive. If we use the resources carefully then they will last indefinitely. But if we use them wastefully and excessively, they will soon run out and all will suffer. The excessive waste is happening in our rainforest every minute of every day of...

...will discuss deforestation across the globe and how it affects the world’s ecosystems. Everyday, a piece of Earth’s ecosystem is demolished by human hands for the conquest for timber, minerals, and other resources. Forests cover 2% of the Earth’s surface, 6% of the landmass, and yet they house half the animal and plant species while rainforests cover twice that area. Deforestation is occurring across the globe on a scale that if it were continue at its present rate the forests could disappear within the next one to two hundred years. This raises concerns and questions. First, why should we be concerned? Second, what kind of damage could deforestation lead to animal and plant species, human existence, and to mother Earth and its atmosphere? Third, how and why the rainforests benefit the human race. To answer these questions, this paper will discuss where the most deforestation is occurring and the consequences of deforestation. Tropical rainforests are defined by two primary factors: location and amount of rainfall they receive. Rainforests receive from 4 to 8 meters of rain a year. Most of the rainfall is blocked by heavy vegetation, and water reaches the forest floor by rolling down branches and trunks. A distinctive characteristic is that the rainforests have no seasonality or no dry or cold season of slower growth. In addition, they are the Earth’s oldest living ecosystems. The rainforests are a priceless part of mother earth and their removal through deforestation would mean...

...some think it is due to the increase in greenhouse gases which trap heat that would otherwise escape from Earth. However, greenhouse gases, such as water vapour, carbon dioxide, methane and nitrous oxide, are an important part of our atmosphere because they keep Earth from becoming an icy sphere with surface temperatures of about 0°F. However, over the past century or so the amounts of greenhouse gases within our atmosphere have been increasing rapidly, mainly due to burning fossil fuels, burning of tropical rainforests, aerosols, air conditioners, chemicals released from decaying organic matter such as swamps, landfill sites, animal dung but deforestation also plays a huge part in the warming of the earth. Deforestation is clearing Earth's forests on a massive scale, often resulting in damage to the quality of the land. Forests still cover about 30 per cent of the world’s land area, but swaths the size of Panama is lost each and every year. Forests are cut down for many reasons, but most of them are related to money or to people’s need to provide for their families. The biggest driver of deforestation is agriculture. Farmers cut forests to provide more room for planting crops or grazing livestock. Often many small farmers will each clear a few acres to feed their families by cutting down trees and burning them in a process known as “slash and burn” agriculture. Deforestation also drives climate change. Forest soils are moist, but without protection from sun-blocking tree cover...

...DEFORESTATION 1. Introduction The year 2011 is ‘The International Year of Forests’. This designation has generated momentum bringing greater attention to the forests worldwide. Forests cover almost a third of the earth’s land surface providing many environmental benefits including a major role in the hydrologic cycle, soil conservation, prevention of climate change and preservation of biodiversity. Forest resources can provide long-term national economic benefits. For example, at least 145 countries of the world are currently involved in wood production. At the same time, Sufficient evidence is also available that the whole world is facing an environmental crisis on account of heavy deforestation. Nobody knows exactly how much of the world’s rainforests have already been destroyed and continue to be razed each year. Deforestation is a major issue in today’s era. In the name of modernization, man has cut down trees in great numbers that has lead to the destruction of great forests and the lives of many animals and plant species. We fail to realize that trees are the most important aspects of our planet and the existence of tress does play a vital role. 2. What is Deforestation Deforestation is the conversion of forest to an alternative permanent non-forested land use such as agriculture, grazing or urban development. Deforestation is the permanent devastation of native forests and woods. Deforestation is affecting our environment and the way...

...Mateo Vargas Mrs. Cox English IV per. 3 12 November 2015 Deforestation By the time that you finish reading this article 324 football fields or 428 acres worth of forests will be lost to deforestation. Yearly this is a rate of thirty five million acres of forest loss. This is equivalent to a space the size of Nicaragua.*** Deforestation is the long term or permanent loss of forest cover and its transformation into another land use. Deforestation happens when forests are cut down faster than they are renewed.*** Deforestation has been occurring since the beginning of human development. The rate of deforestation has increased over time with the development of new technology. Technology allows for people to clear forests faster and do more harm....

...Innovation and Sustainability Why is controlling human production and consumption important to our material resources this earth has created for us? This is the essential question so many are asking in today’s society. Many decades have been addressing the ecological impacts of consumptions and production therefore air quality has improved, waste and industrial pollution has been controlled more and products are more proficient with more informed consumers to boot. As we know these are steps in the right path, however more must be done to manage consumption and production of our material resources. Elemental changes are needed in how natural resources are removed and the way products are produced, dispersed, used and disposed of. Action is needed at all levels of society from individuals and industry through to central and local administration in order to reverse past and current trends and live within biological limits. Thus in this thesis, I will discuss two material resources of consumptions and productions that humans are constantly producing and consuming and how we can potentially decrease them. The first consumption called deforestation often leads to a production such as farming. The second consumption to be discussed is urban sprawl, which leads to the production of water pollution. However, let us first define deforestation and urban sprawl. “Deforestation commonly defined as the elimination of trees and other plants from forest areas more quickly than they can be replanted...

...Humans have geographically altered the world. Sure, for billions of years, the earth has been changing itself, but humans have done a much faster job. Humans, with our awful habits of deforestation, burning fossil fuels, and causing drainage, are ruining our earth. At first glance, global warming is good for the earth. It would undeniably prevent another ice age from occurring. On the other hand, it would also cause hurricanes, which is bad. Human actions have become the key factor of the earth’s changes. These actions have become way more dangerous than any natural force. George Perkins Marsh, an American geographer, lawyer, public servant, and philologist, took it upon himself to make it known that human actions were changing the earth, for the bad. Marsh, in his book Man and Nature, showed like no one had before the effects man had on the environment and why it mattered. Man and Nature remains today a geographical classic. Marsh compares the earth to a home and man to the tenant. He essentially says man is ripping out the carpets, breaking windows, and letting the ceiling collapse. I definitely agree with that statement. Through the years, evidence of human transformation of the earth has presented itself to me. The hurricanes of 2004, for example, are a result of global warming. The ocean is warmer and the winds stronger, which makes for a very powerful hurricane. And hurricanes, or course, cause damage to homes, cities, and even states. Hurricanes Charley, Frances,...

...Industrialization has had an effect on biodiversity hotspots because things such as industrial chemicals are being misused and spilled into the environment or leaked into the air that have a very large effect on the worlds biodiversity hotspots and the organisms that exist within those areas. Another aspect that has harmed biodiversity hotspots all over the globe is the idea of urbanization. Many biodiversity hotspots exist in places that are not inhabited by humans which allows such hotspots to function normally and on their own without interruptions. The idea of urbanization however has led to biodiversity hotspots being compromised purely for the sake of expanding the human races land even further to a point where one day every acre will be covered by housing, businesses, and other facets of an urban environment which will in turn destroy all biodiversity...

...Our Earth, birthed four billion years ago has existed to shape life for organisms that thrive among it, but as of recently there has been a massive disturbance. As stated by universetoday.com, humans have first came to existence 200,000 years ago, but were fully settled only 6,000 years ago. Despite settling only less than 10% of Earth’s life span, humans have contributed to the most damage inflicted to the Earth itself since its whole lifetime. Not only is it due to simple deforestation; humans have over mined Earth’s resources, reduced biodiversity and increased pollution dramatically. As of the past, humans were not educated so they initially survived based on their natural prime instincts, but as centuries flew by major problems began to...
