Natural And Man Made Pollution Environmental Sciences Essay

Natural And Man Made Pollution Environmental Sciences Essay Pollutions are two types. The natural and Man Made. The natural pollution is caused and produced naturally and will not affect our environment because of its regeneration ability. The Man made pollution is being made by humans and have huge affect on our environment and definitely ourselves. The reason of increasing the pollution daily is because of raising of population of the world since it is getting bigger there is need to contact to the environment to provide the necessaries of humans. By developing the new technologies and using them to reach and discover new resources people have had a harmful affect on the planet. It is clear that the small population with new technologies will not affect the environment or if it is affecting it is not that much an can be controlled while huge population by using the technologies will clearly have bad results for the planet. Pollution is one of the major issue and concern. It has not been happened recently or accidently. It is human`s mistake since long years back and has been beside us since many years ago . We must be clever try hard to save our energies and resources and we have to have a good management and programs to protect the resources that we are using nowadays which we might not have them in coming years. We should use them usefully and try to prevent any type of pollution to our Environment and save the earth and resources for our future and provide a better living place. In General There are 6 ( Six ) types of pollution . Which we are going to discuss about four of them that it is believed to be the major ones. Air Pollution Water Pollution Radioactive Pollution RADIATION POLLUTION Radiation is any kind of ionizing and nonionizing radiation that is caused by human activity. Nuclear power generating plants are the well known source of generating radiation; however there is other ways in which radiation is also emitted like: any nuclear devices, medical X rays microwaves and experimental research laboratories. However the amount of radiation that are emitted is considerably less than the nuclear power generator plants but is nuclear plants the amount of radiation al always under the check by the workers and specialists. In case that the radiation level is increasing in nuclear reactors; the specialists will shut down the reactor or decrease the nuclear chain reaction. (Radiation, library.Thinkquest, 2011) Radiation has bad effects on both land and human health. The land that is exposed to radiation will not be unfertile and if something grows on the land will have considerably high amount of radiation in the fruits and vegetables which is really bad for human health to consume. Radiation takes hundreds of years to vanish. If a person is exposed to radiation it is very dangerous and can lead to cancer, anemia, burns and vomiting. In some cases the genetic disorders are caused by radiation such as: mutation over long period of time mostly in off springs. The effect of radiation to human health depends on the amount of radiation that the person is exposed to and there is also many more such as: the length of exposure, kind of radiation, age, and the individuals health and also exposed body parts. Nowadays exposure to radiation is minimal because of technological advancement. However it can come from damaged nuclear plants, accidents from transporting of nuclear fuel and wastes. (The effe cts of radiation, biology-online, 2011) Nuclear wastes must be stored in heavily shielded sealed containers and be stored in areas away from biological habitats the safest storage sites are in deep caves or abandoned salt mines. To avoid radiation prevent over exposure to x-rays and CT scans, avoid living near nuclear plants or stay there for too long and stay clear of radioactive materials and elements. Radiation exposure is a real danger. As Japan is battling its worst nuclear crisis. Radiation leakages threaten the health of the entire humanity. In Time Magazine, Prof. John K.C. Leung gives advice on radiation exposure how to avoid radiation exposure. Remember nuclear radiation exposure can travel through clouds. It doesnt really matter where you are. If the radioactive atomic materials can travel through air, then it can go anywhere.(According to newsbalita, 2011). John K.C. Leung explains that the general protocol for those who find themselves in danger of exposure to nuclear material should; stay indoors the walls will provide some measure of protection from the radiation, close the windows and doors plus turn off the ventilation system. Various people support nuclear experimentation and suggest that by the help of technological advancements and the above safety precautions, radiation pollution/exposure can be controlled and avoided for example according to (biology-online, 2011)Today, high level exposure is very rare due to the advancement of technology. It could come from defective or badly damage nuclear plants, ammunitions of factories, and nuclear war. However radiation moves everywhere and its hard to contain for example experts say radiation can travel through clouds. It doesnt really matter where you are. If the radioactive atomic materials can travel through air, then it can go anywhere (newsbalita, 2011) Water pollution Water pollution is an undesirable change in the state of water, which contains harmful substances. It is an important environmental issue like Air pollution .Water pollution is the physical, chemical and biological properties of water which contains harms other living organisms. Polluted water is unfit for drinking and for other consumption purposes. Since its polluted, it harms human beings and other living organism which use water as it contains viruses, bacteria, intestinal parasites and other harmful microorganisms. It also causes diesis such as diarrhea, dysentery, and typhoid. Due to pollutants entire ecosystem gets disturbed infected. The causes of pollution are disease-causing agents. These are bacteria, viruses, protozoa and parasitic worms that enter sewage systems and untreated waste, oxygen-demanding wastes which can be decomposed by oxygen-requiring bacteria. Oxygen levels in the water depletes when large amount of decomposing bacteria converts, which becomes the causes of death of other organisms in the water, such as fish. Another pollutant of water is water-soluble inorganic pollutants, such as acids, salts and toxic metals. Large quantities of these compounds make the water unfit for drink and cause death of aquatic life. Nutrients are also water pollutants, they are water-soluble nitrates and phosphates that cause excessive growth of algae and other water plants, which deplete the waters oxygen supply. Its dangerous as, it kills fish and might kill child if found in drink water. Water Pollution Causes Although certain natural processes may cause some of the water pollution, however, the largest cause of our seas, rivers and lakes getting polluted is the human activity. We use water every day both in our industries and at homes. We get this water from groundwater sources, rivers, and lakes, and after using it, and often contaminating it, most of this water gets back into the rivers, lakes, and oceans. (Water treatment purification, 2009) A major problem in developing countries is the disposal of sewage, as there is no adequate sanitation in large areas, thus carrying disease causing bacteria and viruses into sources of water. In countries that are developed, people often flush pharmaceutical and chemical products into their toilet. (Water treatment purification, 2009) Air pollution Substance in the air that cause harm to humans and the environment are known as air pollutants. Pollutants can be in form of solid particles, liquid droplets, or gases. In addition, they may be natural or man-made. Pollutants can be classified as primary or secondary. Usually, primary pollutants are directly emitted from a process, such as ash from a volcanic eruption, the carbon monoxide gas from a motor vehicle exhaust or sulfur dioxide released from factories. Secondary pollutants are not emitted directly. They form in the air when primary pollutants react or interact. Example of a secondary pollutant is ground level ozone, one of the many secondary pollutants that make up photochemical smog. Some pollutants may be both primary and secondary that is, they are both emitted directly and formed from other primary pollutants. (Pollution Greenhouse gas) Air

A New Frontier for Social Media

The evolution of speech and communication is amazing. From grunting and signing to Tweets and Social Media rants. There was a time when a quite Sunday afternoon on the front porch swing would have capped Off good long week. Now, people are bombarded thousands of times a day with commercials, pops and spam email, Just to name a few. The horizon of modern day speech and communication is changing and not for the better it seems.Something that is interesting and thought provoking is the idea behind Alex Wright's statement from the essay, â€Å"Befriending, Ancient or Otherwise†, he states, â€Å"The more time we spend â€Å"talking† online, the less time we spend, well, talking. And as we stretch the definition of a friend to encompass people we may never actually meet, will the strength of our real-world friendships grow diluted as we immerse ourselves in a lattice of hyperlinked â€Å"friends†? † (Wright) This is the reality in which one lives today; it can be seen and heard every day.Whether it is listening to conversations on the local commuter train or reading resumes of a younger generation's workforce, the disparities of an ever-changing royalty are real. A conversation can hardly be held and not here the word â€Å"like† used almost every other word or when a resume come across the desk of a hiring manager and it has â€Å"text† language used in it (l want 2 work 4 u). It is mind-blowing that the applicant does not realize that this is unacceptable and what is even more shocking, is the individual usually does not understand why they should not receive the Job because of this.These changes can also be seen in the way people communicate via email. In the essay, â€Å"Airmail and Merrimac† by Eric Winner, he explains the differences in emails n a simplistic manner but what really comes through, is the differences in culture. Wiener's assessment of the American people and their electronic communications is compl etely accurate. American are as Winner states, â€Å"a bundle of contradictions: rambling and yet direct; deferential, yet arrogant†. Winner) Americans do not mean to be one-way or the other concerning their emails, it is Just an extension of who they are. Americans, as Winner eluded to, have allowed the email to replace the telephone. This can be seen in American's social media post, it is as if they are trying to relay all of the human emotions into a Backbone post, text, or Tweet. With all of the testing, emailing, and social media, society is losing its ability to communicate effectively, in person at least.If an individual cannot communicate effectively, then the problem discussed in Caroline Regis's essay, â€Å"The Fine Art of Complaining†, which was that individuals are not taken seriously due to their inability to communicate effectively, will continue to perpetuate. Ergo stated that, â€Å"effective complainers are people who act businesslike and importantâ € . (Ergo) An individual can have a very strong and intimidating presence in a room or meeting. However, their ability to communicate effectively goes out the window the minute they sit behind a computer. Sure, they can relay their thoughts well.They can even, as Winner puts it in â€Å"Airmail and Merrimac†, be contradicting, they can ramble and yet be direct; they can be deferential, yet arrogant. What they cannot be is confident, courageous, and patient. They can't have humility or tenacity. They can't show presence or be a great orator. Without the ability to be great orators or masters of the spoken languages, society will continue to struggle to communicate across the ethnic divides. Amy Tan described in her essay, â€Å"Mother Tongue†, her mother's predicament in relation to her mother's â€Å"broken† English.That it was hard for her mother to communicate with other people when she had to use her â€Å"broken† English. With the isolation and hum an avoidance that social media allows for, it is inevitable that this ethnic language bridge will continue to grow. One can see firsthand what social media is doing to the younger generations, when they start to look at who they are befriending and who they are following. It is sort of a friendship/followers dilemma, here it is not about the quality of a relationship but the quantity of relationships, that defines a great social circle.It is the â€Å"lattice of hyperlinked â€Å"friends†, as they only care about how many followers they have and not about who is following them or what reason. Therefore, as Society ventures into the New Frontier of Social Media, these are the ways, which technology and communications of today are shaping the younger generations. As older adults have had the opportunity over the years to exercise their social acumen, they are less likely to fall complete victims of the heinous future. However, the younger generations have not had the same oppo rtunity.

Farewell Speech Essay

â€Å" Every new beginning comes from some other beginnings end. † – Seneca. Middle school ended and now High school has begun. We all go into high school not knowing what to expect. Like if you’ll have the same classes as your best friend, if you’ll have nice teachers, or if you’ll get dumped in a trash can on â€Å"Freshman Friday. † The toughest thing is not knowing which of your friends for middle school will be at your school and which ones won’t be, if your best friend is going to a different school then you. But it’s O. K. high school is a new beginning we get to reconnect with old friends from elementary school and see our friends from last year to. As time goes by and with each of our classes you build new friendships that strengthen as the year goes on. The more you get involved in school the more you get to become friends with more people. I did Cheerleading for school this year and I have no regrets, I made so many new friends because of it they’re like my sisters now. I was also a wrestling manager and that was great I can’t wait to do it again next year, I didn’t only become close with the other managers I also became close with the wrestlers, they’re like brothers now. But no matter how many friends you made in high school you never lose touch with the ones you had in middle school. Every Freshman had those â€Å"Freshman Fears. † Some not as bad others, but everyone has them. Like the fear of â€Å"Freshman Friday† it’s funny because we never actually had that. It’s something they say to scare us†¦. And it works every time. We worry about if we have good teachers or not. Most of them are, but that’s your own opinion. Will we have a lot of our friends in our class? Are they going to have the same lunch as us? We get scared that we’ll get lost in the hall ways, or seniors will run us over. We have so many worries because of what we hear about high school, and that sense we’re the youngest in the school we have the worst teachers. It’s not like that at all in fact this year of high school was great, I wouldn’t change it at all. Yeah, this year wasn’t perfect, there was still drama and fights, but once everyone got past all that this year was really fun. Football games were always fun, everyone went to them and had a great time. Pep rallies are interesting, especially when the seniors and juniors try to win the spirit stick. A lot of people try to make high school sound scary and horrible, but it hasn’t been bad at all. I’ve had a great year and can’t wait to see how the rest of high school will be.

Essay about The Important Role of News Reporters - 2236 Words

The Important Role of News Reporters Every morning when I get up, the very first thing I do is turn on the TV--but not for cartoons or MTV. It has become a habit for me to watch the news in the morning. I feel the need to know what is going on because I know that no matter where the news happens, 99 percent of the time it will, directly or indirectly, affect me or people I care about. The broadcast media has become a part of my life and the lives of almost everyone in the Western world. We may not know the names of our senators, but Katie Couric or Tom Brokaw are familiar names in every American household. Not many of us realize, however, that the job of the news reporter is not as glorious as we imagine. This paper will offer you a†¦show more content†¦It is believed that the audience will not put any special effort in trying to comprehend the story--if it is confusing, they will change the channel. This applies especially to the broadcast media. Unlike a reader with a newspaper, the listener/viewer does not h ave an option of rereading a confusing sentence for better understanding. If one aspect of a story is missed or misunderstood because of poor wording, there is no way of rewinding the tape to get back to it. Therefore, broadcast journalists must be very clear and concise in their writing and try to avoid long names, titles, or big numbers. To illustrate this point, here is a newspaper paragraph. Try to read it out loud like a newscaster and decide if it is easily understandable to a driver who is battling the morning traffic while listening to your newscast. Surgeon General William H. Shearer announced today that Charles R. Mahaffey, 45, chairman of the US Pharmaceutical Corporation, had succeeded Donald P. Ingraham, 64, president of the National Educational Media Association, to head the governments Anti-Smoking Campaign starting next month (Shook 13).
