With the rapid development of technology, people can easily do what they could not do before. The popularity of cell phones is one of the most obvious examples. Ancient people could not even imagine the invention of telephones, let along portable ones! Cell phones do bring various functions which cannot only connect people around the world but also offer entertainments. In the mean time, they also bring some side effects or diseases to human bodies.
The main function of cell phones is to contact people far away instantly, (mostly when people are outside the houses and have no telephones nearby.) This makes great difference for human beings, and the invention of cell phones surely is a milestone in the history of communication system. Cell phones were not so commonly used when they were just invented. They were too expensive and luxurious for most people to afford. Since more and more companies are producing cell phones, the prices have been going down. Studies have shown (and we can see in our daily life) that in Taiwan, almost everyone has one cell phone, and some even have more than one! People can use cell pones anywhere, anytime. The magical device has changed the human being’s life and communication.
The styles and functions of cell phones tend to follow the new fashion so that people would like to buy them not only for the basic function. The cell phones are combined to be a multiple media player. They can serve as a camera, an mp3 player, a dictionary or even a game station. A few years ago, people started to surf the Internet through cell phones, which was another progress in communication. Therefore, people rely more on high technology, especially cell phones. They can talk to their friends while walking on the street, play the games while waiting for the bus, and even throw away their alarm clocks because cell phones can serve the purpose, too! However, they have some invisible side-effects which will do harm to the health.
While many people are too dependent on mobile phones, they are not aware of the danger they may encounter. During a conversation through a cell phone, it will produce some harmful waves and destroy the brain cell little by little. If one person keeps on chatting on cell phone for a very long time, he/she might easily get fatal disease such as brain tumor. Thus, some scientists and doctors suggest people reduce the time they use cell phones. Another debatable issue is the pollution mobile phones do to the natural environment. Like other technological equipment, they can become a pollutant to the nature after being thrown away. People usually just see what they want to see, and overlook the damage they have done to the world they are living in.
So, next time when purchasing a new cell phone, people should balance the interest between themselves and the environment, and consider if they really need a new one.
