Effects of Global Warming on Polar Bears Essay Example Effects of Global Warming on Polar Bears Essay Effects of Global Warming on Polar Bears Essay No 1 is safe from the rough effects of planetary heating. But if there is one species which suffers the most. they are the polar bears who can merely last under highly cold clime. Although their existent population is difficult to find. they are believed to be about 20. 000 to 25. 000 found throughout the Arctic Ocean and next seas ( World Wildlife Organization ) . Polar bears’ home ground is about covered by sea ice all twelvemonth unit of ammunition ( Great Bear Organization ) . The country is said to hold a delicate ecosystem. necessitating longer clip to alter and to retrieve when disrupted or damaged. However. research shows that the Arctic is most likely to be ice free between 2013 and 2040 for the first clip in history. The part has been sing cutting of the polar ice cap due to warming of temperatures. With the thaw of the ice comes the devastation of the life of the species which thrives in the Arctic. Polar bears. seals. including endangered species like seahorses and giants. are forced to withdraw to environment less suited for their brand up. Further. scientists fear that big sums of liquid ice enter the North Atlantic and interrupt the planetary current form. The thaw of the Arctic ice besides entails smaller runing country for polar bears. Sealing waxs are their favourite and they can non track them where the sea is unfrozen. They besides eat workss. including berries. roots. and kelp. but none of these can fulfill their Calorie demand. Their organic structure needs big sum of fats from Marine animate beings for they are active year-round. Decrease in Arctic sea ice can take to 67 percent loss of the full polar bear population in 50 old ages ( Bear Planet Organization ) . Though polar bears are exposed to other hazards such as pollution. oil and gas geographic expedition. legal and illegal hunting. planetary heating remains the biggest menace to their endurance. They experience malnutrition and famishment due to habitat loss. Melting ice force them to shore before they have acquired adequate fat militias to last the period of scarce nutrient during the late summer and early autumn. Thining ice are surface hard to walk on because they deform more easy which makes it more hard for them to run for nutrient. They besides need to swim wider spreads between ice which farther used up their energy and sometimes take to submerging. Malnourished female polar bears result to take down generative rates and lower endurance rates among greenhorns and juvenilles ( Rosing. 2006 ) . Thining ice make it difficult for grownup females to happen couples. And when they do happen 1. the difficult pursuit starts for a suited pregnancy lairs. Underground lairs have inclinations to prostration or have low insulative power to supply heat for freshly born greenhorn. Dens built on multi-year ice may see motion that may ensue in longer distances for female parents and immature greenhorns to walk when they return to seal-hunting countries. There is besides a hazard of disease-causing bacteriums and parasites to boom more readily in a heater clime. In Western Huson Bay. ice interruptions up earlier than it did 30 old ages ago during late spring season which shortens the hunting season for polar nears ( National Wildlife Organization ) . Their population declined by 22 per centum from 1987 to 2004 and their organic structure status is much different. weighing 60kg igniter in 2004 than in 1980 when likely pregnant female polar bears weigh around 290kg. In 2005. Alaska recorded four drowned polar bears who made longer swim than they usually do when runing for nutrient. Alaska besides documented higher mortality rates among polar bear greenhorn and different denning sites for pregnant polar bears. Photos and pictures of polar bears’ battle are everyplace. In 2008. US Department of the Interior listed Polar Bears as threatened species under the Endangered Species Act and thaw of the sea ice in the Arctic as the biggest danger to their endurance ( The Humane Society of the United States ) . They are the lone species aside from elkhorn coral and staghorn coral to be put on the said list. However. the determination was reversed following the commercial and scientific informations that they are increasing in Numberss in the past 30 old ages. As it presently stands. the US Fish and Wildlife Service see polar bears as threatened species intending anytime their home ground will disappear and their position will alter to endangered before they finally become nonextant. In Canada. polar bears were recommended by the Committee on the Status of Endangered Wildlife in Canada to be placed under the list of species of particular concern . This list allows for a direction program to be written in five old ages. which was criticized by World Wide Fund for Nature as being excessively long to do a substantial impact to habitat loss from climate alteration. Since their current position is threatened species. it is non excessively late for attempts toward salvaging their home ground from farther debasement ( Bear Planet Organization ) . The simplest but the best manner to extenuate the effects of planetary heating is to halt C dioxide ( CO2 ) emanations. Recycle and reuse merchandises and utilize energy efficient contraptions to cut back CO2 in the ambiance. Polar bears deserve a opportunity. Bear Planet Organization. Polar Bears and Global Warming.

Recommendation Letter Requirements How to Find

Recommendation Letter Requirements How to Find SAT / ACT Prep Online Guides and Tips Along with researching your colleges’ deadlines and requirements, you also need to figure out exactly what each one’s policy is toward recommendation letters. Some schools may ask for one or two letters, while others may actually prohibit them outright. This guide is meant to help you locate the crucial information you need. First, we’ll go over the questions you need to ask. Then, we’ll take you through the process of searching for this info, step by step. To begin, what do you need to know? What Do You Need to Know About Recommendation Letter Requirements? Before you can make sure you have all the answers, you need to know what questions to ask. There are a few key answers you need to gather: How many letters do you need? More specifically, do you need one from your counselor? From a teacher? If so, do you need one, two, or (in rare cases) three teacher recommendations? Does it matter who you ask? Do you need to ask teachers of a certain subject, or can you ask anyone? Does your school have any special requirements, like a personal, artistic, or peer evaluation? (This is rare, but applies to a few schools.) Can you send a supplemental recommendation? Does your school encourage, discourage, or prohibit extra letters? How do your recommenders submit their letters? Do they upload them on tothe Common Application or school application? If necessary, can they send them via mail? And last, but not least - when’s the deadline? These are the most important questions that need answers. You should be able to find this information on each school’s admissions website. If it’s not spelled out there, then you should feel free to call up the admissions office and ask. Some schools won't even read letters if you send them, like those in the University of California system, while others make space on the Common App for you to submit two additional teacher letters, like Brown. More commonly, schools want one or two teacher recommendations, but it's important to check because there's such a range of policies. Since every school’s website is different (and some are inexplicably confusing to navigate), let’s go through the steps of researching a few popular schools with differing policies towards recommendation letters. Let’s start with schools in the University of California system, and then take a look at the University of Virginia and Harvard. The journey begins. How to Search for the University of California’s Recommendation Letter Policy Your first step for all these schools should be to head to Google. Search for â€Å"name of school + admissions† and findits admissions page. PrepScholar also has a large database of colleges and their requirements and admissions rates, so you can find data by searching for â€Å"PrepScholar + name of school.† Every admissions site is a little different, so you may have to do a little digging around before getting to the information you need. Often a page called â€Å"Application Instructions† or â€Å"Application Checklist† will get you where you need to go, usually along with choosing whether you’re a U.S. prospective freshman, transfer student, or international student. On the University of California admission page, you’ll see its rec letter policy in a sidebar: â€Å"UC does not require (nor read) letters of recommendation at the time of application. A campus may ask for them later as part of a supplemental review, so be sure to check your email.† You can see why it’s so important to check policies. Not only does UC not require you to send a rec letter, but it won’t even read one if you do! What’s the lesson here? Always do your research before sending any supplemental recommendation letters. When you create your online account to apply to a UC school, you’ll see that there’s no tab to invite recommenders. For other schools, this will be part of the school’s app or Common Application. Now let’s take a look at the University of Virginia, which asks for one counselor and one teacher recommendation. How to Search for University of Virginia’s Recommendation Letter Policy Back to Google! Start by searching for â€Å"University of Virginia + admissions.† Double check that you’re in undergraduate admissions, by the way, if your college has a graduate school. Once you get to UVA’s site, you’ll see a dropdown menu where you can click on â€Å"Instructions.† These instructions tell you to send â€Å"recommendations from one counselor and one teacher.† You can also click on School Forms and Deadlines for more detailed info. If you’re wondering about UVA’s policy towards supplemental letters, unfortunately its website doesn’t say. Not to worry! A search of â€Å"UVA + supplemental recommendation† brings up the UVA blog. According to this blog, UVA doesn’t really want you to send an extra letter, but will consider it if it really adds something significant to your application. Generally speaking, it’s discouraged. Finally, let’s consider Harvard and its guidelines for recommendation letters. How to Search for Harvard's Recommendation Letter Policy The first step should be old hat to you by now. Head over to Google and search for "Harvard + admissions." Once you get to Harvard's admissions page, you can click on "Application Requirements." Then select whether you're a freshman applicant, transfer student, or visiting student. Here you'll find that Harvard wants to see the evaluation from your counselor and two teacher letters. Compared to other Ivy League schools, Harvard's website is pretty tight-lipped about what it's looking for in teacher recommendation letters. All it really says is, "Ask two teachers in different academic subjects who know you well to complete the Teacher Evaluation forms." The website does refer you to its posts in the New York Times blog for more insight into the admissions process. According to this blog, recommendations are "extremely important" in the admissions process. Officers read them "with great care" and look for "such personal qualities as character and leadership as well as intellectual curiosity, creativity, and love of learning...[they] can offer evidence of an applicant's potential to make a significant difference to a college community and beyond." As you can tell, recommendation letters are closely reviewed in Harvard's process, as well as at other selective schools. Also like other schools, Harvard seems to consider supplemental recommendations if they truly add something substantial to your application. At the same time, it neither expects nor encourages them. Now that you know how to track down your schools' recommendation letter policies, you also want to make sure you know how to submit them. How Do Your Recommenders Submit Their Letters? If you're applying through the Common Application, then you'll invite your recommenders to upload their letters. As long as you fill in their name, position, and emails correctly, then the rest is up to your recommenders. The same should go for a school's individual online application. Since Harvard allows you to submit a supplemental recommendation, it leaves space on the Common Application for you to assign an "additional recommender." If your recommender can't upload her letter online for some reason, you should be able to send a hard copy by mail to the school's admissions office. In this case, make sure to provide your recommender with a pre-addressed, pre-stamped envelope, and to follow up with her that she sent it off by the deadline. If you're clear on all the guidelines, then you can communicate them clearly to your recommenders. Let's briefly review what that key info is. Key Points to Remember There's a lot of planning that goes into asking for recommendation letters and getting them submitted. Make sure to search online for each of your school's rec letter policies, which should be outlined on its admissions page. The schools mentioned here don't specify exactly who you should ask for rec letters, but some schools do give guidelines. MIT and CalTech, for instance, instruct you to ask one humanities or social studies teacher and one math or science teacher. If you still have questions that aren't answered online (unfortunately, sometimes they won't be), you should contact the admissions office directly. The people there will be able to get you the information you need. Finally, be thoughtful and intentional about who you ask for recommendation letters, whether they're your core recs or supplemental ones. You want to make sure each letter adds something insightful, complimentary, and substantial to your story. If your letters accomplish this, then they can be extremely helpful in tipping the admissions decision in your favor. What's Next?
