Free Essays on Pollution

Air Pollution The plant stretched it’s leaves out toward the sun in hopes of growing strong. Yet it was only to find out that it would not survive because there was no sun. Instead a thick layer of smog blanketed the sky. Humanity has not yet reached this point, but if we continue on this path then this dismal future will become a reality. One of the greatest dangers effecting us today is pollution. Pollution is a problem created by human carelessness and disregard for the planet. One of the most detrimental types of pollution is air pollution. Much of the world's air has been poisoned by chemical wastes. Life in some places has ceased because the air is not fit to breath. People all around the world are exposed and are at risk to many diseases, such as lung cancer. Plants and animals also feel this effect, as they have become endangered or even extinct. Yet we are not at a total loss. As a result of our actions, governments have passed laws to limit or reverse the threat of environmental pollution. In researching air pollution we discovered that the single major cause of air pollution is the internal-combustion engine of automobiles. This is because gasoline never completely burns in the engine of a car. Once it is released into the air, the un combusted products (soot, ash, and other solids), unburned hydrocarbons, carbon monoxide, sulfur dioxide, nitrogen oxides, ozone, and lead then undergo a series of chemical reactions in the presence of sunlight. The result from these reactions is a smelly haze like substance called smog. Smog may appear brownish in color when it contains high concentrations of nitrogen dioxide, or it may look blue-gray when it contains large amounts of ozone. In either case, prolonged exposure will damage your lung tissue. Cars aren’t the only contributor to our air’s pollution. Factories also require huge amounts of fuel, coal and oil for our industries. When these fuels... Free Essays on Pollution Free Essays on Pollution Air Pollution The plant stretched it’s leaves out toward the sun in hopes of growing strong.

Free Essays on Pollution AIR POLLUTION including WHO's 1999 Guidelines for Air Pollution Control Exposure to air pollution is as old as the use of fire by human beings Air pollution, both indoors and outdoors, is a major environmental health problem affecting developed and developing counties alike. It comes from sources of dust, gases and smoke, and is generated mainly by human activities but also naturally. When inhaled, air pollutants affect the lung and respiratory tract but can also be taken up and transported by the blood stream throughout the body. Through deposition in the environment, air pollutants can also contaminate food and water. Health impact Every year millions of people die or suffer serious health effects from air pollution: mainly respiratory diseases, asthma, chronic obstructive pulmonary disease, cardiovascular disease and cancer of the lung. An estimated 3 million people die each year because of air pollution (see Figures for breakdown); this figure represents about 5% of the total 55 million deaths that occur annually in the world. It is possible, because of uncertainty in the estimates, that the actual death toll is anywhere between 1.4 and 6 million annually. Many studies consistently show the direct link between mortality rates and daily ambient concentrations of suspended particulate matter that have diameters below 10 m m. Life expectancy can be significantly reduced in communities with high levels of particulate matter. Indoor air exposure to suspended particulate matter increases the risk of acute respiratory infections, one of the leading causes of infant and child mortality in developing countries. In Asia, such exposure accounts for between half and one million excess deaths every year. In sub-Saharan Africa the estimate is 300,000-500,000 excess deaths. Around 30-40% of cases of asthma and 20-30% of all respiratory diseases may be linked to air pollution in some populations. Studies in So Paulo, Brazil, have shown that a 75 ... Free Essays on Pollution Companies should be held liable for their own pollution What is pollution? Pollution is "to make impure and to contaminate with man made waste." as defined by Webster dictionary. Pollution is the introduction of harmful substances or products into the environment. It is a major problem in North America and as well as the world. Pollution not only damages the environment, but also damages our vital life sustaining needs such as the water we drink. Pollution problems have arisen in all industrialized areas as well as in various inland and coastal waters. Everyone at one time or another has probably heard the phrase "every dollar counts". In fact, this is very true to big business corporations and companies because they make every dollar count even if it pollutes the water which, organisms depend on. Pollution is an obvious problem in our world today. Therefore, it is extremely important that we take action by making companies pay for their own mess, because soon there will be serious consequences that we may face in the future which, migh t lead to our extinction on earth. The greatest source of pollution lies in the companies that produce toxic wastes such as power-plants. Although not common, companies have been known to dump their waste products into streams, lakes, and rivers. This may seem like a relatively small occurrence, however it arises an immense problem that threatens the life of all living things. Mutations, destroyed ecosystems, and human death have all occurred as a direct result of illegal dumping. When a company dumps their waste in our lakes, it contaminates our drinking water and soil. The consequence of this is that it kills all the vegetation and prevents it from every growing back for a very long time. Due to the lack of vegetation and clean water it also causes entire communities of humans including animals to move on to new places and not to return for at least a century. A century is may seem too long fo...

How to Send ACT Scores to Colleges

How to Send ACT Scores to Colleges SAT / ACT Prep Online Guides and Tips ACT scores are in, and now it’s time to move onto the next step - college applications! You may be wondering how to send your scores and whether you’re making the right choices about which ones you'll allow colleges to see. In this article, I’ll go through how to decide which scores to send and the way the process works overall. Should I Send My ACT Scores? ACT has a built-in Score Choice policy that allows you to send only certain scores to colleges based on how well you do on each test date.If you’re very unhappy with one of your ACT scores, you don’t necessarily have to show it to schools.There are some schools that require you to send all of your scores, but most allow you to pick and choose which test dates you want to send. In order to decide which scores to send or whether you need to take the test again, you should take a look at the score range for your schools of choice.Read this article to learn more about finding your target ACT score.As a general rule, you should aim for a score that represents the 75th percentile of scores for admitted students for your school of choice (meaning your score is higher than 75% of the scores of admitted students).If you’re still not sure whether you should take the ACT again, read our guide to help you decide! You should also consider superscoring as a factor.Colleges that superscore will take your highest scores from each section of the ACT across multiple tests and average them to create your highest possible composite score.Read this article for more information about how superscoring might affect your strategy on the ACT. How to Send ACT Scores to Colleges You can send your ACT scores to colleges several different ways, but the easiest way is to order score reports throughyour ACT web account.Click on the link that says â€Å"Send Your Scores† in your account homepage.You will get something that looks like this, with more dates listed if you took the ACT more than once: Once you select the date you want to send on your report (remember, every test date requires a separate report even if you’re sending more than one to the same school), you will get to a screen that asks you to fill in the code for the school where you want to send it.You can also search for schools to find the appropriate code: You can select up to 8 test date and school combinations per score report order. This is what it will look like when you select a school: You have the option to select either standard or priority reports (more on this in a minute!).After you select the schools and test dates you want, you just have to enter in your credit card info and hit submit, and your score reports will be on their way! Other methods of sending score reports include: Downloading the score report request form and mailing it in Calling the ACT (this costs $15 extra just for the call and is ONLY for priority reports - again, I'll talk more about those in a minute) Sending a letter of request to the ACT (instructions can be found at this link) To find the correct ACT college code for these other score reporting methods, use this link.

Types of ACT Score Reports There are three different types of ACT score reports. I'll describe each type and why you might or might not decide to order it. Type 1: Free Reports Whenever you register for the ACT, you have the option to send four free score reports.This is an enticing offer, but it can hurt you if your scores don’t end up being up to par, and you might not even know where you’re applying yet. Overall, I’d say it’s better to forgo the free reports and wait until you get your scores back.Unfortunately there is no fee waiver available for score reports, but as I said, most schools will allow you to use Score Choice and just send your best score to avoid the extra fees. Type 2: Regular Reports Regular reports (reports sent after the free score report period) cost $12 per test date per school.This is another reason why it’s to your advantage to use score choice - it's in your best interest to send the minimum number of score reports to reduce your financial burden. After the ACT gets your regular score report request, it will take about one week for them to process it and send it to your school of choice.Reports are delivered depending on the schedule of the school, but it’s almost always within two weeks or so of your request. Type 3: Priority or Rush Reports Priority reports for the ACT cost $16.50 per test date per school.These are processed two days after the ACT receives your request, as opposed to a week after the request for regular score reports.Priority reports should reach your school within 3-4 business days of your request.These reports can only be sent within the US. Be careful with rush reporting, because some schools that only receive scores electronically may not review these types of reports any faster than regular reports.Read more about when to order rush reporting here. Your priority score report is strapped to the back of a cheetah by the ACT - the cheetah's brain has a GPS implant. Some admissions officers might get bitten, but it WILL be there in time. Summary The process of sending your ACT score reports shouldn’t be too challenging if you know what to expect.Remember that most schools allow score choice, and many of them offer superscoring as well. You should check with your colleges of choice about their policies.You should also be sure you’re ordering reports with enough time to spare so they make it in with your application. Priority reports should be a last ditch option. As long as you'reaware of deadlines and know your options, sending ACT scores to colleges is a cinch! What's Next?
