Banning Cellular Phones

The following rough draft is a student's first paragraph of an argumentative essay.

Cellular phones have become a must-have accessory for most people today. Not only can you make a call with a cell phone, but you can send messages, play games, check social media, and stay informed with news headlines. Many people have become addicted to their cell and cannot go anywhere without one. Kids use cellphones in school and professionals use them as a means of conducting business. Public places are littered with people on cell phones communicating with others, and not with each other. Some would say that cell phones are just part of life in the modern world. Others disagree and say that people have become too dependent upon these devices and they should not be used in public places.
