The positive and negative impact of the cell phone Positive aspects The positive effects of cell phone include the essential role the device plays in emergencies， and the opportunity the device allows for convenient communication. It is becoming a necessary component of modern civilization. Convenience From staying on-call with the office to calling home from the grocery store， owning a cell phone provides convenience. Regardless of whether your job or home life requires you to stay in contact， a cell phone improves your accessibility， especially as payphones become harder and harder to find. Many phones， especially smartphones， also provide convenience with utilities such as calculators， maps and reference materials. What’s more， cell phones save lives. Making emergency calls from a cell phone when someone is injured makes it possible for emergency responders to get to the injured person much faster. In the event that someone is injured in a remote location， cell phones are crucial since the injured person might not get help at all otherwise. Cell phones also have the positive effect of facilitating communication to a point that learning and business become considerably easier since you can call wherever you are. Negative aspects On the other hand， the convenience of cell phones leads to their use even when another option -- or simply staying off of devices entirely -- would work better. People make calls on cell phones even while near a landline， leading to dropped calls and poor reception. Smartphone owners browse the Web and work using mobile apps even when a computer could get the same job done faster and with less struggle. People also use their phones at inappropriate times， such as at the movies or a restaurant， causing disruption for others. If you want a cell phone for its convenience， remember that it's a tool like any other: better for some jobs than others. According to the National Safety Council， 1.6 million crashes occur each year due to drivers using cell phones for conversations or texting. This comes out to around 28 percent of all crashes. Using a cell phone while driving can at crucial moments. There’s also some concern that texting(发短信) distracts people from other things they should be doing such as working on homework or talking to the people in the same room as them. Health Concerns Some people worry about health risks， such as brain cancer， from long-term cell phone use. Scientists continue to investigate the issue， but as of publication， the FCC states there is no current evidence that "establishes a definite link between wireless device use and cancer or other illnesses." If you're uncomfortable holding a cell phone up to your head， consider a Bluetooth headset， which uses a much weaker wireless signal than the phone itself.
