The National Post reports in its Wednesday, June 10, edition that this week, Prime Minister Mark Carney will announce a ban on social media for kids under 16. Postmedia's Tasha Kheiriddin writes that we have not seen the details yet, but Canadians should applaud this move. Every day, we see more evidence of the damage social media does to children. Social media is addictive, damaging mental health and exposing kids to predators, creating a public health issue. If tech companies will not keep children off their platforms, Ottawa should intervene. Excessive screen time also harms adults' brains, but a two-week break from social media can reduce anxiety, improve mood and attention, and clear brain fog. Social media is addictive, and its delivery mechanism -- the smartphone -- enables that addiction. If the PM really wanted to be audacious, he would ban the purchase of smartphones for children, not just social media. Of course, Ms. Kheiriddin says parents could act on their own and buy their kids no phone, or just a "dumbphone," thereby saving themselves a pile of money and grief. The question is, why don't they? Maybe if they stop scrolling, and see how it feels, they will.
