One of the main reason cell phones might have the potential to harm us human beings are because of a form of electromagnetic radiation called radiofrequency energy. Electromagnetic radiation can be categorized in two types: ionizing and non-ionizing (National Cancer Institute). Here is why this is a problem, exposure to ionizing radiation is known to increase the risk of cancer. However, in regards to non-ionizing radiation, like microwaves and ovens, there is currently no evidence that relates non-ionizing radiation to a risk…
Radiation is all over the place, and cannot be escaped. But the amount that one is exposed to can be lowered. Cell phones do not generate large amounts of radiation, but give off an amount similar to that of a large toaster oven. With over 300 million cell phone subscribers in the United States alone, it is not hard to see why this could cause a problem (CNN Health). Tissues in close contact to a radiation-emitting device will absorb radiation, so when one holds a cell phone near their face for an extended period of time, the radiation enters his/her body through the skin (National Cancer Institute). Over the last decade, research on radiation has increased tremendously, but there were no prior studies performed, especially on children. Through recent studies, the International Agency for Research on Cancer (IARC) has listed cell phones as “possibly carcinogenic to humans.” New studies, launched in 2010, are tracking individuals for twenty to thirty years monitoring their health related to their cell phone use (Cancer Risk).…
In “Extra large, Please,” Alice M. Davies focuses on the increase of obesity with children, which schools are provoking. There are many various social problems in kids of America today ranging from poverty to drug abuse. One alarming factor that is rapidly exploding is childhood obesity. Alice Davies’ article, “‘Extra Large,’ Please,” which describe the alarming social problem of childhood obesity connected to the fast food industry in America today. Davies stated: “the number of American kids who are dangerously overweight has tripled. More than 16 percent of our children qualify as ‘obese’” (Davies). Although childhood obesity is a growing problem stemming from a terrible diet and lack of exercise, we can take action now to avoid further detriment towards their future health. The first cause of childhood obesity is the lack of inactivity. Many schools are not required to have any physical education. Unfortunately, Davies’ states: “Many of those schools are so short of money they’ve scrapped physical-fitness classes” and “too few communities have athletic programs in place.” It is terrible that schools have a hand in this growing epidemic. Also, Spurlock’s Supersize Me documentary shows that “schools are cutting out recess to study for testing and only one state requires physical-fitness classes.” It is terrible that most of these children taking exams are obese. In addition, they live in a dangerous neighborhood where they can’t go out and play because drug activity and violent crime may make playing outside dangerous. Communities should take part in making the neighborhood a safe haven for kids to play outside. The second cause of childhood obesity is poor eating habits. Children will rather eat candy instead of focusing on the products that are good for the body. Parents play a major role when it comes to allowing or giving their child food that will damage the body more less providing nutrients. Children need to leave the junk food behind…
Cellular phones are now an integral part of modern telecommunications. In many countries, over half the population use mobile phones and the market is growing rapidly. At the end of 2009, there were an estimated 4.6 billion subscriptions globally. In some parts of the world, mobile phones are the most reliable or the only phones available. The world now has over 5.6 billion mobile phone users. Cell phones emit radiofrequency energy, a form of non-ionizing or electromagnetic radiation, and tissues nearest to where the phone is held can absorb this energy. The majority of the radiofrequency energy emitted by a cell phone is absorbed by the hand and head of the user. The total energy absorbed is a function of the specific absorption rate (SAR), duration of use, and the manner in which the cell phone is used. In addition, people are concerned that cell phones might have the potential to cause certain types of cancer or other health problems. Possible damage in our tissues, increase in the risk of brain glioma and risk of tumors by heating the cells in the head and neck are three possible cancer-causing effects of radiofrequency (RF) energy of cell phones. The use of speaker mode or a hands-free device, a cell phone with a low SAR value, and reducing the amount of time spent on the cell phone are three ways to reduce RF exposure.…

Mobile phones are one of the most common information access devices with almost 31% of the global population having access. This exploratory study investigated usage patterns of, and attitude about, cell phones among university students in a mature market (United States) and a rapidly growing new market (India) by surveying students in each country. Key findings from the study include similarities in the usage of phones to communicate with others and in the perception of mobile phone usage in public settings, and differences in the use of text messaging and opinions regarding driving and mobile phone usage. Overall these results suggest students in India use mobile phones differently from their American counterparts. In a developing market like India, mobile phones may be the primary and only phone to which students have access.…
In today's society, it's unusual that we see people without a cell phone nowadays. We even see kids who have phones.

Consumers have when choosing between different mobile phone brands. The study was built upon six key attributes (telephone features, connection fee, access cost, mobile-to-mobile phone rates, call rates and free calls) related to mobile phone purchasing respondents had to importance rate. The research showed that consumers with prior experience about a product can predict their choices relatively well, although respondents tended to overestimate the importance of features, call rates and free calls and underestimate the importance of a monthly access fee, mobile-to-mobile…
