EPA essays

EPA essays Prior to the 1920s, very few people were aware of the term or concept biosphere, and prior to the 1960s minimal people knew the term environment. Beginning around the 1930s, literature concerning this topic began to appear. Up until this time Americans thought of the natural world as being a storehouse of raw materials intended for human economic purposes. In the late 60s, Americans began to recognize an emerging crisis. They had seen firsthand serious environmental destruction. They lived near polluted lakes where it was too gross to swim or fish. They lived in grimy, air-polluted cities. They witnessed DDT killing wildlife. They were eating pesticide-ridden foods. People suddenly became aware of the environment. They realized that it isnt indestructible or invincible, and that humans were having a negative affect on the environment. This awareness sparked a concern among some Americans and thus began the conservation movement. The conservation movement sought to ensure wi se use of the latent wealth of nature. In 1965 the Conservation Foundation held a conference on Future Environments of North America. As a result of this conference many concerned authors published literature outlining the proceedings. These writings contributed to a heightened public awareness of an endangered environment. They began to bring political concerns to the public eye. Environmental pollution became a huge public health concern. Of course the conservationists did have many critics. At first it was considered just another special interest group similar to groups supporting women, seniors, gay men and lesbians, ethnic groups and cultures lobbying for attention. They faced huge critics in the developing stages. Hard scientists and engineers such as oil geologists, industrial chemists, etc. argued humanitys ingenuity and perseverance woul...

BPA fetal exposures affect male and female development and quality of Research Paper

BPA fetal exposures affect male and female development and quality of life as adults - Research Paper Example In essence, early exposure to BPA, as well as other chemicals, especially in the foetal stage signifies an increase in the risk of disease later in life. This paper will examine the impact of BPA in adults following foetal exposure. Health Concerns Some of the risks involved with foetal exposure to BPA include increased risk for prostate cancer in adult men and breast cancer in both women (Okada et al 32). In addition, foetal exposure to BPA results in adverse metabolic changes, early onset of puberty and decreased fertility. Furthermore, immunological changes are also a major consequence of foetal exposure to BPA (Rubin 30). Whenever foetal exposure to BPA occurs, the chemical infiltrates the body in an active fashion. BPA binds to the body’s oestrogen receptors replicating the functions of oestrogen. Furthermore, in both male and female adults, BPA causes adverse reproductive effects, particularly in populations exposed to BPA due to their occupations. During the initial 11 weeks of gestation, which is a time when most pregnant women are unaware of their pregnancy, the internal communication systems, and organs of the foetus develop quite rapidly, thus are extremely sensitive to external pressures. Organs such as the brain and mammary glands develop during gestation, thus experience a prolonged period of vulnerability to the effects of BPA, especially since foetal development of such organs is susceptible to oestrogen fluctuations. Additionally, in certain instances, BPA has been shown to cause obesity. When BPA binds to oestrogen receptors in the human body, it causes alternative estrogenic effects, which start outside the nucleus. The alternate path caused by BPA ultimately alters lipid and glucose metabolism, resulting in weight gain (Rubin 31). This is primarily since the alternative oestrogen receptors trigger pathways that result from exposure to BPA to rework the functions of vital components that play a significant role in metabolism, for insta nce, adiposities and pancreatic B cells. In a recent study, it was confirmed that foetal exposure to BPA has the capacity to potentiate the systems inherent in the central dopaminergy. This is bound to result in marked super sensitivity to the drugs linked to abuse-induced reward implications. In essence, by affecting mesolimbic dopamine activity, BPA causes adverse effects such as attention deficits, hypersensitivity and an increased sensitivity to drugs linked to abuse. Furthermore, BPA is also known to bind to receptors of the thyroid hormone, and possibly cause certain side effects on its functions. For instance, BPA impacts triiodothyronine in adults following exposure to the chemical during the prenatal development phase (Rubin 33). Researchers now consider that there are actually two ways through which BPA interrupts the regular endocrine function (Okada et al 32). The compound can perform as a weak estrogen, which binds to the estrogen receptor. It also can, on the other han d, impede the impact of stronger natural estrogens, restraining estrogen function. They are usually considered performing in the cell nucleus via the estrogen receptors, which control gene expression. Many other ways of BPA action are considered to be related to its biological

Effects Research Paper - Essay Example Arnas (2006) used children in the age 3-8 years bracket with a total of 347 respondents. The study included the parents as well since some respondents were still young to comprehend the questions. Arnas found out that about 50% of the ads viewed by children during their TV exposure are food related. Because of this 40% of the respondents requested their parents to buy the foods shown in the ads and about 9% of them are even insistent. Arnas' concern is that most of these foods are high in fats and sugar which are associated with obesity, diabetes, and other health problems. Hitchings and Moynihan (1998) in the other hand used children within the 9-11 age brackets but used limited number of respondents. A total of 44 children across varying social class were involved. Their findings show that a relationship exist (r=0.58) between the type of ads observed by children from TV to the type of foods they eat. The more alarming fact is that most of these foods contain high sugar, fats, salt , and preservatives like crisps, softdrinks, and savoury snacks. The results of the two studies mention... But the result is enough to prove that eating habit of children between 9-11 is related to TV food ads they saw and recalled.. More intensive study with greater number of respondents could have shown higher positive relationship. This effect may not only be associated with food advertisements but also with other products as well. It has shown that the television medium is a good way to educate the viewers and a good means to present new ideas and programs to the target client. These findings can be a good start for private individuals, groups, or government institutions planning to launch programs, projects, or products. Opinion about the implications of the research for parents and society. In the context of parents and the society as a whole, the results of these studies can be both viewed as promising and alarming. They have both advantages and disadvantages. The findings are alarming in the sense that food manufacturers and food marketing firms are aware that the television medium is a good tool to push their products and that they are taking advantage of this potential in order that their products be recognized by their target sector. The worst thing is that several manufacturers are less concerned about the health effects of their product. In all cases, obviously, these ads do not mention negative aspects about consuming their products. Their primary concerns are the increase in sales the ads would bring the company. Since most ads do not include warning on over-consumption, children may think it is fine to eat them as they like thereby jeopardizing their health. The results' implication can be promising if government

The Land is Mine Essay -- Hebrew Scriptures

The author identifies and analyzes six discrete land ideologies found in the Hebrew Scriptures that have influenced its readers. (preface) In his book land refers to not only as physical realities where there is dirt and rocks, and where plants are growing, and where humans build their cities. Land refers to a social symbol with a range of meanings in which we construct its meanings for ourselves.(p.1) A subtle distinction between theology and ideology can be ; biblical theology is the doctrine and discourse about God expressed within a biblical literary unit that reflect the living faith of a given community, and Biblical ideology is a wider complex of images and ideas that may employ theological doctrines, traditions, or symbols to justify and promote the social, economic, and political interests of a group within society.(p.10) The evidence that they both are closely interrelated can be found in the biblical Prophets such as Jeremiah or Amos The author has taken five basic categories of analysis for exploring the land ideologies. ; Dominant images of the land, Location of God ( what is God’s position relative to the land?), Locus of power in the land (locus of power and interest), Charter justifying entitlement to the land (who is justified in claiming and why?), Rights to/of the land (what rights do people have to the land?) (p.14) Land as the Source of Wealth: A Royal Ideology This justifies the king’s right to control and rule the kingdom and basically â€Å"to this royal land ideology are the concepts of the land as the source of wealth, the divine right of the monarch to appropriate that wealth, and the entitlement of the monarch as God’s representative to have dominion over the whole earth as an empire.†(p.17) The author ... ...tes respect the ownership of the land YHWH holds. YWH is a local landowner and the land is YHWH’s extended sanctuary.(p.99) Land as Host Country: An Immigrant Ideology Abraham immigrated with his household to Canaan to settle down. In the course of Abraham’s journey to the land, he did not have to confront with hostile indigenous people; it is written â€Å"They set forth to go to the land of Canaan, and they came to the land of Canaan.† (Gen. 12:5) (p.118) Abraham shared the land through generous grants, peaceful negotiations, or legal purchase. Abraham found God at sacred sites. Abraham’s rights and responsibilities were not those of a monarch or conqueror, but involve acknowledging YHWH as the host deity, teaching justice to the Abraham household, establishing peaceful relations with the peoples of the land, and dealing justly with the land itself.(p.132)

American School Versus Chinese school Essay

I am a Chinese girl, growing up and living in China for 18 years. Last year, I went to the United States. Although I have lived here less than two years, I found a lot of differences of two countries’ education style, such as the teaching style, the school life/rules, and the academic environment. The first difference is teaching style of two countries. In America, students are always divided by several groups. Each group has six or four students, and they can discuss questions during the class time, which can help students improve spoken skills and to learn dialogue and debate. After class, they probably have group homework which they need to finish together. Students need to prepare class presentations with a lot of PowerPoint every few week. That can help students improve their public speaking skill, confidence, share with knowledge, understand what they learned, and take a leadership role. The class lecture is delivered by teachers so that students can study by themselves first. In class they can answer questions anytime they want, and instructors will not be annoyed. Students call their instructors first name, and their instructors would like their students do that (Echo Lu, 1). Second, America school life is different from China school life. In American school, students take class at eight o’clock in the morning, and they finish at three o’clock. Students only have one hour to eat lunch and most of them take lunch from home. They have different classrooms when they take a different class. Students only have two big exams, excluding small tests in classes. They get A, B, C, D, or F as their final grade before the end of the semester, and Ding 2 it is according to homework, tests, participation, attendance, presentations, two or three big exams. After class, they can go home take school bus or drive by themselves. Some of them take part in clubs in school, such as sports (soccer, baseball etc. ), performing arts (dance, dram, band etc. ), outdoor education (scouting, campfire etc. ) and so on (Wikipedia). On weekends, students always hang out with friends, they can together with a boy and they allow to date with a boy, and are allowed sleepover in girl friends’ house. Furthermore, AmericaacademicenvironmentisdifferentfromChina’s. Itshowinfour different points: the curriculums and learning environments; class size and examination system. America students can choose their classes, and they have a lot of interesting classes to choose from core classes: Spanish or French, computer, marketing and so on (America High School). They are free and unrestrained (go to bathroom, drink water, laugh). The classroom atmosphere are natural, active and relaxed. American school, every class has 25-30 students, and teachers teach five or six classes. Students can take 7 times SAT exam or ACT exam each year. They can use the highest one to apply universities. However, a high grade is not the important point to enter a famous university. The university will consider very comprehensive and then decide whether you could be enrolled or not. First, they will consider your specialty, especially if you were good at P. E. then you will have more advantages. Second, they will think about social skills, such like part-time job experience, volunteering experience and so on. Also, they will think about what clubs or other activities you had ever taken part in in high school. In Chinese schools, every student has seat. Students cannot discuss questions in the class; they only have individual homework, and it is a lot. Teachers never ask students to prepare  presentations, and class lectures will not delivered. Students cannot answer the questions anytime they want; they must raise their hands first and get permission from teachers. They must say Ding 3 â€Å"Hello† to their teachers when they meet in school. Every time before students take class, they need to stand up and say† good morning† or† good afternoon† to teachers and can only sit down when teacher say they can. Students must respect their teachers very much and can† only call faculty members by their last name with a title like Mr, Ms, and Dr. It is thought to be rude to call their teachers’ first name. In Chinese schools, students go to school at 7 a. m. in high school and go home at 10 p. m. They have two hours to have a break at noon and go to school at two. They can eat lunch at school canteens or go home to eat lunch, but they eat dinner at school. Students will not change classrooms, and they have 8 minutes to go to bathroom each 45 minutes class. Most of them go home by themselves; schools will not provide school buses, but a few students will be picked up by their parents. They get a score before the end of the semester for each subject. Teachers will range students according to grades in class and year level. They even show the results to all students and send a text to their parents. Students have big exams every month in middle school and high school. They need to choose to learn art (Chinese, Math, English, History, Politic and geography) or science (Chinese, Math, English, physics, Chemistry, Biology) in grade 2. In China, students almost do not have any extracurricular activities. Some schools have clubs but only a few students take part in. Most student their teacher do not allow them to take part in clubs. On weekends, students usually stay at home do their homework, sometimes they  are allowed to hang out with friends. But girls cannot with a boy, similarly a boys cannot with a girl. Students are not permitted to date before they go to the university. In Chinese school, students only take normal classes; they even do not have art and music. Students use all the time to study, the learning environment in China is extremely Ding 4 competitive and demanding. Almost every student works hard, they are determined to be at the top of the class and to become straight-A students (Bohan). In China, each class has 60-70 students, and teachers teach 2 classes. The head teacher will stay in office all the time, you can ask questions anytime. Other subject’s teachers will go to your classroom during the self- studying time from 7p. m. to 9 p. m. Chinese students only have one time to take college entrance examination, which take place every June. Selection is based on each students scores in this exam (6 subjects), and due to the number of people sitting in exam. America and China are two different countries. Different culture, social system, history, population; therefore they have different education system. Nobody can say which one is better,  because for their own country it is the best one. But America or China still need to revolutionize the bad part, learning from each other and other countries.
