Technology is too improve. Even, our life is easier than with variety materials. Children is using to this like adults. For instance, there are opportunities such as video games, internet, facebook to spend their time. Although most of family allow to these but, I think these are very harmful most respects such as health, social life and waste of time.
 First, there are a lot of harms to health. For axample video games addiction at a lot children. So, they may be eye disorder to ever not leave from in the its. Moreover video games can caused pyschological problems. For instance, children may have got bad behavior. So video games are  harmful to caused behavioral-disorders.
  Second problem is on waste of time. Children have got a lot of waste  time. 70 percent of children prefer to play the video games instead of doing homework or reading book. So, they spend  their valuable time to pointless like this. Thus they can not improve.
  To sum  up, video games have got harms much more benefits such as health problem, social life and waste of time. Clearly, they is not necessary for them.
