Top 5 Environmental Issues Essay Example for Free
Top 5 Environmental Issues Essay 1. Population Explosion Whether we like to admit it or not, our very own rapidly multiplying presence on this planet is the biggest environmental problem there is, and itââ¬â¢s getting bigger by the minute. We voraciously consume resources, pollute the air and water, tear down natural habitats, introduce species into areas where they donââ¬â¢t belong and destroy ecosystems to the point of causing millions of species to become endangered and, all too often, go extinct. It took nearly all of human history ââ¬â from the first days of man on earth until the early 1800ââ¬â¢s ââ¬â to reach a global population of 1 billion. In just 200 years, weââ¬â¢ve managed to reach 6.5 billion. That means the population has grown more since 1950 than in the previous four million years. Weââ¬â¢re adding roughly 74 million people to the planet every year, a scary figure that will probably continue to increase. All of those mouths will need to be fed. All of those bodies will need clean water and a place to sleep. All of the new communities created to house those people will continue to encroach upon the natural world. 2. CO2 Levels in the Atmosphere Greenhouse gas emissions caused by our modern way of life ââ¬â vehicles, power plants, factories, giant livestock farms ââ¬â will bring devastating climate change within decades if they stay at todayââ¬â¢s levels. Average temperatures could increase by as much as 12 degrees Fahrenheit by the end of the century if emissions continue to rise, a figure that would easily make the world virtually uninhabitable for humans. A global temperature rise of just 7.2 degrees Fahrenheit would cause a catastrophic domino effect, bringing weather extremes that would result in food and water shortages and destructive floods. The most recent report by the Intergovernmental Panel on Climate Change represents ââ¬Å"the final nail in the coffinâ⬠of climate change denial, representing the most authoritative picture to date that global warming is caused by human activity. According to the panel, we must make a swift and significant switch to clean, efficient and renewable energy technolog ies in order to prevent the worst-case scenario. 3. Polar Sea Ice Loss Polar sea ice is melting at an unprecedented rate, and itââ¬â¢s not showing any signs of slowing down. Itââ¬â¢s perhaps the most dramatic, startling visual evidence of global warming, and itââ¬â¢s got scientists rushing to figure out just how big of an effect the melting is going to have on the rest of the world. British researchers said that the thickness of sea ice in the Arctic decreased dramatically last winter for the first time since records began in the early 1990s. The research showed a significant loss in thickness on the northern ice cap after the record loss of ice during the summer of 2007. Scientific American warns that ââ¬Å"human fingerprints have been detectedâ⬠on both the Arctic and Antarctic regions. Antarctica had previously appeared to be the only continent on the planet where humanityââ¬â¢s impact on climate change hadnââ¬â¢t been observed. The collapse of the Larsen B and Wilkins ice shelves in the Antarctic Peninsula shows just how fast th e region is warming. 4. Destruction of the Rain Forest ââ¬ËSaving the rain forestââ¬â¢ has been at the forefront of the environmental movement for decades, yet here we are facing huge losses in the Amazon all the same. You might have thought that, with all the attention the rain forest has gotten, it wouldnââ¬â¢t need so much saving anymore ââ¬â but unfortunately, global warming and deforestation mean that half of the Amazon rain forest will likely be destroyed or severely damaged by 2030. The World Wildlife Fund concluded this summer that agriculture, drought, fire, logging and livestock ranching will cause major damage to 55 percent of the Amazon rain forest in the next 22 years. Another 4 percent will see damage due to reduced rainfall, courtesy of global warming. These factors will destroy up to 80 percent of the rain forestââ¬â¢s wildlife. Losing 60 percent of the rain forest would accelerate global warming and affect rainfall in places as far away as India. Massive destruction to the rain forest would have a domino effect on the rest of the world. The WWF says that the ââ¬Ëpoint of no returnââ¬â¢, from which recovery will be impossible, is only 15 to 25 years away. 5. Mammal Extinction One in four mammals is threatened with extinction. Thatââ¬â¢s 25%, a huge number that will totally change the ecology of every corner of the earth. We could see thousands of species die out in our lifetime, and the rate of habitat loss and hunting in crucial areas like Southeast Asia, Central Africa and Central and South America is growing so rapidly, these animals barely have a chance. If you think the extinction of an animal like the beautiful Iberian Lynx is no big deal, and wouldnââ¬â¢t have that much of an effect on the planet, think again. Not only would we be losing ââ¬â mostly due to our own disregard for our surroundings ââ¬â so much of the awe-inspiring diversity of nature, mass extinctions like this would cause a serious imbalance in the worldââ¬â¢s food chain. When a predator disappears, the prey will multiply. When prey dies out, the predator will see its ranks decrease as well. Many people fail to realize just how interconnected all species on this plan et really are.

What the Cinderella Story Has to Teach Young Girls Essay -- Literature
At first glance, what makes a fairy tale a fairy tale may seem obviousââ¬âsome kind of magic, hidden symbols, repetition, and of course itââ¬â¢s evident itââ¬â¢s fictionââ¬âbut fables are more than that. As Arthur Schelesinger puts it, itââ¬â¢s about ââ¬Å"[expanding] imaginationâ⬠and gaining understanding of mysterious places (618). While doing this, it also helps children to escape this world, yet teach a lesson that the reader may not be conscious of. A wonderful story that achieves all of this is Cinderella, but not the traditional tale many Americanââ¬â¢s have heard. Oochigeaskw, or The Rough-Faced Girl, and Ashputtle would be fitting for a seven-year-old because they get the gears of the mind turning, allowing for an escape on the surface, with an underlying enlightenment for children of the ways of the world. The Rough Faced Girl is the Native American variation of Cinderella. It was originally told in the language of the Algonquin, who resided in the Eastern Woodlands of the United States and greatly differs from all the other stories of Cinderella. This taleââ¬â¢s focus is of an invisible man who will marry the woman who can see him. His sister, who has the ability to view him, cares for him and brings different woman to the wigwam to test their sight of the ââ¬Å"Invisible Oneâ⬠(639). Many woman tried as they might, are unable to see him except one, Oochigeaskw. This woman is the youngest of three siblings, and is treated the poorestââ¬âscars covered her body from where her sisters burned her (640). I prefer this story to the rest because there isnââ¬â¢t the use of magicâ⬠¦or magic for the womanââ¬â¢s own benefit. Instead, once the sister proves The Rough-Faced Girl can see her brother, she bathes her and all her scars disappear. My interpretation of this is tha t Ooch... ...on. Works Cited Behrens and Rosen.

Global Warming Paper Essay
Global temperatures on the Earthââ¬â¢s surface have increased by 1.1 degrees Fahrenheit during the last century, faster than any time in the last 1000 years (Rauber 41). Consequently, the 1990s was the warmest decade in the last 1000 years (ââ¬Å"Global Warmingâ⬠). As humans emit fossil fuels, greenhouse gasses slowly warm the Earthââ¬â¢s atmosphere (ââ¬Å"EPA Globalâ⬠). This gradual process is known as global warming. As glaciers begin to melt, sea levels rise and coastal areas in Florida may suffer immense losses (ââ¬Å"Beach Erosionâ⬠). Floridaââ¬â¢s tourist economy may also suffer a tremendous loss, as well as agriculture (ââ¬Å"Florida Scientistsâ⬠). With a warmer atmosphere, disease will spread quicker and human health will be threatened throughout the state (ââ¬Å"Global Warmingâ⬠). Serious action needs to be taken in order to slow the process of global warming. Global Warming is an increase in the temperature of the Earth due to the use of fossil fuels and industrial processes that build up to the emission of greenhouse gasses, mostly carbon dioxide and methane (ââ¬Å"Global Warming Threatensâ⬠). As energy from the sun strikes the surface of the earth, it turns into heat which, in turn, releases the heat as long-wave infrared radiation (Crowe). Gasses in the air, such as carbon dioxide, methane, nitrous oxide, chlorofluorocarbons, and water vapor, trap some of this radiation as it tries to make its way back out to space (Olgesby). These gases trap in heat as do the windows of a greenhouse; therefore, they are called greenhouse gases (Elston). As an excess amount of these gasses are emitted into the Earthââ¬â¢s atmosphere by industries and fossil fuels, the temperature of the Earthââ¬â¢s atmosphere gradually increases (Oglesby). Humans escalate the amount of greenhouse gasses in the atmosphere by burning fossil fuels and by many manufacturing processes (Crowe). In the U.S., from 1990-1997, carbon dioxide emissions have increased 10.7 percent (Elston). This activity and a warming atmosphere are causing drastic changes around the earth, especially in Florida. Global warming poses a threat to Floridaââ¬â¢s beaches and freshwater supplies due to a rise in sea level (ââ¬Å"Southeastâ⬠). Warming the atmosphere will raise sea levels by expanding ocean water, melting mountain glaciers, and melting parts of the Greenland Ice Sheet (ââ¬Å"Beach Erosionâ⬠). The Intergovernmental Panel on Climate Change estimates that the local sea levels may rise 8 to 30 inches by the year 2100 (ââ¬Å"Global Warming Threatensâ⬠¦Ã¢â¬ ). The horizontal advance can be 150 to 200 times greater than the sea level rise, and even greater in areas with a moderate sloping shoreline (Alvarez et al). Consequently, saltwater will be forced to move landward, which shifts the border between saltwater and freshwater inland and causes the encroachment of saltwater into groundwater aquifers (ââ¬Å"Southeastâ⬠). Over the longer-term, a three-foot sea level rise could be disastrous for aquifers in Ft. Lauderdale, Miami and Homestead areas, which are locat ed on the low coastal ridge (Alvarez et al). In addition, rising sea levels put at risk the stateà ¢s number one status as a retirement and tourist destination (ââ¬Å"Global Warming Threatensâ⬠). Hotels, homes, and property within 200 to 250 feet of the current shoreline may be flooded (ââ¬Å"Florida Scientistsâ⬠). This, in turn, will alter the $51 billion annual revenue from Floridaââ¬â¢s tourist economy (ââ¬Å"Florida Scientistsâ⬠). According to the stateà ¢s tourist development agency, 71 million people visited Florida in 2000 (Alvarez et al). Miami Beach alone generates $2 billion a year in tourism revenues, and the Florida Keys generates $1.8 billion annually (Alvarez et al). The stateââ¬â¢s economy will suffer significantly as higher seas flood all property on these beaches (ââ¬Å"Global Warming Threatensâ⬠). Many of Floridaââ¬â¢s cities by the sea, including Miami Beach, Daytona Beach, Palm Beach, Clearwater, Key West, Tampa, St. Petersburg, Pensacola, and Marco Island, will face great hardships due to a rise in sea level (Alvarez et al). A warming atmosphere will also lead to changes in Floridaââ¬â¢s agriculture which is highly sensitive to changes in weather and climate (ââ¬Å"Southeastâ⬠). The production of citrus, sugarcane, and tomatoes adds billions of dollars to Floridaââ¬â¢s economy (ââ¬Å"Florida Scientistsâ⬠). Global warmingââ¬â¢s effects on agriculture will vary by location and on the specific crop (Alvarez et al). Warming temperatures and carbon dioxide fertilization will increase citrus production by about 6 to 20 percent in Florida over the next 40 to 50 years (Alvarez et al). Although citrus will benefit in the short-term, its productivity in the long-run will suffer (Alvarez et al). Citrus yields will begin to decrease once temperatures have gone past the nominal growing range and soil moisture has been reduced from the heat (Alvarez et al). Sugarcane is a $437 million industry in Florida and is mostly located in Palm Beach County (ââ¬Å"Southeastâ⬠). Global warming may sever ely impact the production and sales of sugarcane (ââ¬Å"Southeastâ⬠). If sea levels rise 18 to 20 inches, flooding will intensify and decrease sugarcane yields due to nutrient pollution problems (Alvarez et al). This will decrease sugarcane growth by about 20 percent (ââ¬Å"Southeastâ⬠). Florida is also the nationââ¬â¢s leader in tomato production (Alvarez et al). However, a warming atmosphere could decrease the stateââ¬â¢s tomato production by about 44 percent as a result of shortened growth cycles (Alvarez et al). Global warming will definitely lead to changes in how and where Florida farmers grow crops (ââ¬Å"Southeastâ⬠). With some crops these changes may be beneficial and with others it may be detrimental. Global warming poses several potential health threats to the population of Florida. The first potential health threat is that of bad air quality (Elston). Higher temperatures increase the rate of smog formation, and increased use of fossil fuels could increase a range of air pollutants (ââ¬Å"Global Warmingâ⬠). A major component of smog, ground-level ozone, is formed from nitrogen oxides and volatile organic compounds (Epstein 51). As the atmosphere warms, this reaction speeds up and produces more smog (Epstein 51). Chronic respiratory diseases and obstructive pulmonary disease can be made much worse by breathing ozone (Elston). Carbon monoxide, sulfur oxide, and nitrogen oxides worsen existing cardiovascular diseases and may produce lung irritation and reduced lung function (Alvarez et al). Seniors, constituting 18 percent of Floridaââ¬â¢s population, the young, and those with existing cardiovascular diseases are predominantly at risk (ââ¬Å"Florida Scientistsâ⬠). Many of the germs that cause waterborne diseases, such as viruses, bacteria, and protozoa, survive longer in warmer water (Epstein 55). Serious diseases like hepatitis, cholera, and yellow fever will more easily be transmitted as the lack of clean water and waterborne diseases spread (Elston). The lack of clean water in a drought causes bad hygiene and unsafe rehydration for people who have lost a lot of water from diarrhea or fever (Alvarez et al). Droughts, caused by global warming, favor waterborne diseases, wipe out supplies of safe drinking water, and, thus, concentrate containments (Epstein 55). In addition, vector-borne diseases, such as malaria, encephalitis, and dengue fever, will be more common as a result of a warming atmosphere (ââ¬Å"Southeastâ⬠). Vector-borne diseases are spread by mosquitoes, rodents, ticks, and other insects and animals (ââ¬Å"Global Warmingâ⬠). Rising temperatures will expand the range of many vectors and can play a role in the transmission of the disease itself (Alvarez et al). This is due to the fact that a warmer atmosphere will provide more area in which the mosquito and many other vectors can survive (Epstein 50). Today, 45 percent of the worldââ¬â¢s population live where they might get bitten by a mosquito carrying malaria (ââ¬Å"EPA Globalâ⬠). However, that percentage may increase to 60 percent if temperatures rise (ââ¬Å"EPA Globalâ⬠). The total number of deaths related to heat waves is estimated to double by 2020 (Epstein 50). Floridaââ¬â¢s population, especially the senior population, is a great risk due to the health risks of global warming (Elston). Florida is faced with serious challenges as a result of global warming. These challenges threaten the stateà ¢s natural areas, economic prosperity, agriculture, and human health. The state can avoid such harm by taking action before it is too late. Some solutions include driving efficiently, taking public transit, walking, or using a bicycle (Rauber 41), limiting the burning of fossil fuels for energy (Epstein 57), using compact fluorescent light bulbs, because each can prevent 400 pounds of coal from being burned to make electricity, buying a car which meets oneââ¬â¢s needs, yet is very efficient (Rauber 41), and, finally, plant a tree or protect a forest (ââ¬Å"Global Warmingâ⬠). Trees absorb carbon dioxide and can offset some greenhouse gasses (Olgesby). Serious action needs to be taken now to avoid such devastating harm.

How to Build Writing Skills in Students With Dyslexia
When you think of the word dyslexia reading problems immediately come to mind but many students with dyslexia struggle with writing as well. Dysgraphia, or written expression disorder, impacts handwriting, the spacing of letters and sentences, omitting letters in words, the lack of punctuation and grammar when writing and difficulty organizing thoughts on paper. The following resources should help you better understand dysgraphia and work with students to improve writing skills. Understanding Dyslexia and Dysgraphia Dyslexia and dysgraphia are both neurological based learning disabilities but both have specific symptoms. Its important to learn the symptoms, types of dysgraphia, and treatment options. Dyslexia impacts writing skills in many ways. Students with dyslexia show a significant difference between what they can tell you verbally and what they are able to convey on paper. They may have trouble with spelling, grammar, punctuation, and sequencing. Some may have dysgraphia as well as dyslexia. Knowing how this learning disability affects writing can help you develop specific strategies for working to improve writing skills. Teaching Students With Dyslexia and Dysgraphia Once understood, you can make some accommodations in the classroom to help improve writing and learning in students with written expression disorder. For example, experimenting with different kinds of pens can help you find what is most comfortable for your student, and improve legibility. Written assignments completed by students with dyslexia are often filled with spelling and grammar errors, and the handwriting is sometimes illegible, causing a teacher to think the student is lazy or unmotivated. A plan of action provides a step-by-step approach for organizing thoughts and information to help make the writing process easier. when teaching writing skills to students with dyslexia. Ideas for Lesson Plans Arm yourself with specific strategies to incorporate into your daily teaching that will help you work with students with dyslexia and dysgraphia improve their writing skills. One suggestion is to put away the red pen when grading papers and use a more neutral color to avoid the student becoming discouraged when seeing all the red marks when you return an assignment. Building Sequencing Skills: From the time we are very young, we learn to complete tasks in a specific way, such as tying shoes or using long division. If we do the task out of order, the end result is often wrong or doesnt make any sense. Sequencing skills are used in writing as well, making our written information make sense to the reader. This is often an area of weakness for children with dyslexia. Students with dyslexia can frequently see the big picture but have trouble understanding the steps it takes to get there. Plan a lesson requiring students to take parts of an event or story and put them in the correct, chronological order.Journal Writing: Helps students in middle school practice writing skills by keeping a daily journal. Writing prompts are given each morning or as a homework assignment and students write a few paragraphs. Varying the writing prompts helps students practice different types of writing, for example, one prompt might require descriptive writing and one mig ht require persuasive writing. Once a week or every other week, students choose a journal entry to edit and revise.Create a Classroom Book: This lesson can be used from 1st through 8th grade and gives you the opportunity to teach social lessons as well as writing lessons. As you complete classroom books, put them in your classroom library for students to read again and again, helping them learn about and become more tolerant of one anothers differences.Writing Newspaper Articles: This project not only works on informative writing skills, but it fosters cooperation by teaching students to work together to create a classroom newspaper.Outline Writing Prompt: Teachers often give students writing prompts to help generate writing ideas, however, students with dyslexia may need additional assistance in organizing information. Provide a step-by-step guide that goes through the process of putting together an outline that organizes information.
