Some children spend hours every day on their smartphones.
Why is this case?
Do you think is this a positive or negative development ?

As the life has changed, the way people live today has become more sedentary. Many young people use their mobiles for hours, which is mainly due to the content inside the phones and incorrect parenting skills. In my view, this is today’s norm; it would be best to control how wisely children use smartphones rather than being a sceptic.

Children’s spending hours in front of the screens, first of all, are mostly because of the interesting content – deeply analyzed algorithms – of social media sites. Ranging from simple mobile games to enormous social platforms, they all intend to capture the attention of the users in an effort to extend the time on the platforms. As a result, young people, most of which do not know how the time is valuable, tend to squander their time. Secondly, since at a very early ages, every child tends to cry, wants something unusual, parents give mobiles to make their children silent which is the beginning of the case. For instance, my own uncle’s son, a 4 years old boy, now prefers to watch cartoons or mobile games rather than playing outside.
In my view, using mobiles for hours is natural and could be positive as long as safety rules and a good aim is targeted. As long as we obey such safety rules as keeping distance and wearing glasses, we would notice that the benefits offered by mobiles are irreplaceable. For example, not only do the smartphones assist in education, but also, they enable us to check our health regularly via special gadgets. Furthermore, most of the children today know a number of foreign languages by using cellphones and are optimist about the future. Taking an example from my own experience, my little brother can understand Russian and is dreaming of travelling a number of countries as well as studying in London, as a result of his mobile, I think.
In conclusion, while stimulating content of smartphones and underestimating the early importance of parenting skills are the main drivers of the case, these gadgets have various benefits that we should take into account while judging.
