Over the years, we have seen how cell phone use has affected the development of our society. There are many arguments about the use of these and see how our society ignores them. Analyze the arguments as objectively as possible. This paper will assess these arguments in order topersuade and guide the audience. So you be the judge!

Should we stop using the cellular phones?

More than fifteen years ago, seeing a cellular phone was quite rare. In today's technologically advanced world, just about everyone has one. Adults, teenagers, and even children carry around portable models of the telephone. Its evolution has been rapid and effective from incoming and outgoingcalls to voice messages to text messaging and even Internet. The cell phone has evolved so much that has become a necessary tool, but we have found many problems using this. The use of the cell phone is damaging our society in health and safety aspect, and this is why we have to limit the use.

The first reason the use of cell phones should be limited or stopped is because of the deaths andinjuries caused by drivers using it while driving. A new study (David Strayer, psychology professor, University of Utah) confirms that the reaction time of cell phone users slows dramatically; increasing the risk of accidents and tying up traffic in general. "If you put a 20-year-old driver behind the wheel with a cell phone, their reaction times are the same as a 70-year-old driver who is not using acell phone," said University of Utah psychology professor David Strayer. "It's like instantly aging a large number of drivers."

Cell phone distraction causes 2,600 deaths and 330,000 injuries in the United States every year, according to the journal's publisher, the Human Factors and Ergonomics Society. Strayer and his colleagues have been down this road before. In 2001, they found that evenhands-free cell phone use distracted drivers. In 2003 they revealed a reason: Drivers look but don't see, because they're distracted by the conversation. The scientists also found previously that chatty motorists are less adept than drunken drivers with blood alcohol levels exceeding 0.08.

Second reasons to use awareness and limit cell phone use are the negative health effects. Cell phonestransmit and receive radio frequency (RF) signals in order to communicate. The RF signals from phones fall within the microwave part of the electromagnetic spectrum. This radiation is also referred to as microwave radiation or electromagnetic radiation. In short, Cell phones use microwave radiation to communicate. Electromagnetic waves alter [electric activity of the brain] and cause disturbance insleep; cause difficulty in concentration, fatigue, and headache; and increase reaction time in a time-dependent manner. There’s no argument that cell phones emit an electromagnetic field, which is a form of microwave radiation that enters the brain when the cell phone is held against the ear. A large population study has shown that people who use cell phones for more than ten years on the sameside of the head have a 40% higher risk of certain types of brain tumors. They increase the resting blood pressure and reduce the production of melatonin. They are also implicated in DNA strand breaks.

In addition, the use of cell phones has also been related to Alzheimer’s disease and Cancer. A study by Swedish researchers suggests the link between cell phone use and Alzheimer’s disease:Phones damage key brain cells and could trigger the early onset of Alzheimer’s disease. Researchers have found that radiation from cell phone handsets damages areas of the brain associated with learning, memory and movement. It was performed on rats, which were exposed to radiation equivalent to that of a cell phone for only two hours. The brains were examined after 50 days, and the researchers...
