TV and our children, where is the limit?

My next essay will be about TV and our children, Where is the limit?
I found some pages on internet that say that “TV Is Making Our Kids Fat” also, “3-year-olds who watch more than two hours of TV each day are three times more likely to be overweight than children who watch fewer than two hours and so on”
For all these reasons I chose this topic to create awareness about the problems that we can cause to our kids if we don’t put a limit in the quantity of time that they watch TV.
