Even though computer is one of the important inventions throughout the history, it has many negative sides that couldn’t be ignored. The first negative thing about computer is that it makes people lazy. Many people especially teenagers like to use computer for entertaining, like games, facebook, and chatting. When they are doing those things, they feel relaxed and really enjoy it. Since people can easily have fun and also avoid doing things they don’t like when they are playing computer, this could become a factor that causes people to stay home all day and become too lazy to work or study.
The second negative thing is that it gives bad guys chances to do bad things. Nowadays, people like to post their information online and use internet to shop. Those situations could lead to crime. For example, if I want to buy a book online, I need to enter my information and my debit card number. bad people could see the information and steal money from my account or use my card to buy goods in some ways.
The last negative thing I want to mention is about health. Some teenagers and workers use computers from day to night, we all know that using too much computer could be bad for eyes and it has radiation that is harmful. And so, many people need to wear glasses. People who sit for a long time to use computer are easy to get disease like varicose vein of lower limb and cervical vertebra disease. People who use computers tend to have more chances to get mental disease like depression, hard to fall asleep at night, lose interest to everything.
Computer is very useful and it makes our life easier, but at the same time, we should use it properly to decrease its negative effects toward ourselves when we enjoy the convenience it brings to us.
