Advertising aiming aimed at children should be banned.

*overexposed is already describing how excessive the phenomenon is and it doesn't really need 'blaze' as well

Granted, advertisements (do) have some benefits. Like public service announcements, appealing to people to protect the environment or resist drugs, help pupils(students) cultivate good habits. Another advantage is that advertisements show the latest products, partly facilitating the potential purchaser.

However, when it comes to children-targeted advertising, I think that its disadvantages overweigh(outweigh) its advantages. With junk food advertisements peppered in the media, children become more attracted to unhealthy food and consume more candy, ice-cream or French fries, leading to a higher risk of health problems like obesity. Except Apart fromfor health problems, advertisement may also distract pupils from school work, making the situation even worse.

In addition, advertising targeting at children may probably (two doubtful adverbs not needed when one will do) cause excessive consumption if enterprises (businesses or companies) only care about selling products to make profit(or could say...only care about their bottom line). Easily drawn to new and fancy things, children are especially vulnerable to commercial advertisements, which means once they see a new toy on TV, they just(often) rush to ask their parents to buy it no matter whether they really need it or not(whether MUST have not as part of the sentence...you will often see whether on its own but it is whether or not...always). This cause development of a bad consumption habit, of which juveniles are supposed to get rid.(Maybe...This may lead to the development of unhealthy consumption habits, something that we should try and avoid.)

To sum up, advertisements contain both beneficial sides and adverse sides, but those aiming  aimed at children are more disadvantageous. Therefore, it is essential to forbid commercial adverting advertisements (or advertising) targeting on children in order to purify the growing environment for the young....hope that this helps you.  Your language is awesome, just a few tweaks to make it better and more native sounding.
