Very well written, just a few corrections with misplaced words. Feel free to correct grammar, you are better at it than me, a native speaker!

I have read through the article regarding the media violence, and, as an eight-year-old child’s mother, I notice an increasing number of violent and inappropriate content shown on the television. I am concerned about this phenomenon, media has become a part of everyone’s life, television is one of the major influences in a child’s development, and it can serve a positive, educational role. Yet, with the explosion of technology and even nearly all the media access that come along with it, violence is becoming harder to avoid. It is difficult for us, as parents, to prevent our children being exposed to this inappropriate content.
I have witnessed my own child watched a cartoon in which had characters held the gun and shot each other, and shouting bad words and the next day I heard him saying exactly the same bad words to his friends. It is shocking to think that he spends nearly 5 hours with media every day, that’s even more time that he spends with me! This is definitely a potential risk.
The problem is that high proportions of media, including television programmes, movies, video games or even books, have some depictions of violence. It is widely agreed that children and adolescents can imitate the violence they see on television; heavy exposure to violent media can be a risk factor for violent behaviour.
To reduce media violence, as parent, we can make a choice to consistently expose our kids to the stuff that isn't suitable in the media. The government should also take responsibilities and be in charge of this serious issue of media violence, programmes on TV and other forms of media should be classified according to the content and suitable age. Action is needed, and it must be quick.
