It is thought by some that the use smartphones should be prohibited in public places such as libraries, shops, and public transport, because they can have several negative impacts on society. While others may not agree, I believe that using smartphones in public places has adverse ramifications on individuals and society.

Firstly, some public places such as libraries and transportation centres have rules, requiring that individuals mute their smartphones. However, even when cellphones are muted with the vibration mode turned on, their obnoxious sounds can still cause stress. Sounds of buzzing and loud conversations can negatively impact society. Furthermore, scientists have said that loud noises are potentially harmful to people, because they cause the body to produce hormones which increase stress levels.

Secondly, people are isolated from society when they use cellphones in public. Ever since the smartphone was created, people have been spending more and more of their time isolating themselves, by staring into a screen even when they are with other people. This type of behavior not only makes people more self-centred, but it also prevents people from getting together in real life. This form of isolation has been made even worse in the past few years with the advent of social media applications that work on smart phones.

In conclusion. The use of smartphones in public places can be harmful because it raises stress levels and isolates people from society.
