Technology can be both good and bad. Cell phones are one of the easiest objects to describe technology. Many people think cell phones always useful but not all people think the same way. In Marlboro, New Jersey USA, People are forbidding to use cell phone while driving vehicles. According to International Herald Tribune This could help to reduce accident that causes traffic jam. However, people really need cell phones these days for their business life or social life. On the other hand, I am going to write some more negative aspects and also positive aspects about cell phones. To begin, the fact that cell phones cause DNA and brain damages. Cell phones have frequencies from 1-3- GHz. These frequencies usually called microwaves. Microwaves are forms of the electromagnetic energy that could damage human cells.
Cell phone can have biological damages through heating effects from the electromagnetic energy, this cause: headaches, earaches, blurring of vision, short-term memory loss, numbing, tingling, burning sensations, and bad sleep. Well know facts are that if you talk on cellular phone more than 20 minutes, your brain temperature raises up to 2 degrees. Look at the chart below:
The cellular phone has to radiate radiofrequency energy at the levels high enough to reach base stations (antenna towers) that are hundreds of kilometers away. Since the energy radiated as a microwave which directly affected on the user’s head, this may indicate that there may be a significant risk of developing cancer tumors, foremost brain tumors from the uses of cellular phones. In other way, cell phone has been really popular in the social life, and it seems to be an important device of communication. Almost all of the people own it. However, this could become a phenomenon when cell phones bothering people a lot. Through the ring call or SMS (short messages system), cell phones could distracted some important events like meetings, classes and presentations. In the positive aspects, cell phones are very useful for communications which you can have it instantly and get the news easily. Cell phones help people to know the most updated information around them, checking the stock market rates in a second. Another positive aspect is the function of the cell phones compared with home phones. These small devices are really famous for its entertainment and size. According to the Kompas news paper, 90% people in Jakarta, Indonesia, are looking for the smallest cell phones that have a great, cool entertainment. Cell phones are unlike home phones in that size and features is fixed. People kill the time by playing games, listening to the radio or even taking pictures and send it via email or transfer between cells. To put it simply, cell phones have become a phenomenon technology that always confused people to use it or not, but depends on people’s needs. In my opinions I would not like to chat on the cell phones all day long. Make a good use of the cell phones which can help people to use cell phones without concerning for their health.
