Australia has set a new global trend by banning social media use for children under 16. This bold move is closely watched by politicians, safety activists, and parents worldwide. Europe is following suit with countries like Denmark planning to ban social media for under-15s next year. Denmark’s Prime Minister, Mette Frederiksen, said mobile phones and social media "are stealing our children’s childhood." Norway will set the minimum age at 15 to shield kids from the "power of the algorithms," said Prime Minister Jonas Gahr Støre. Ireland is preparing to verify users’ ages with a digital wallet, while Spain and France consider raising the social media minimum age to 16 and 15, respectively. France also proposes a night time "digital curfew" for teenagers aged 15 to 18. The European Parliament passed a non-binding resolution to ban under-16s from social media unless parents allow it, highlighting social media’s "addictive" nature. However, this resolution won’t become law. Ursula von der Leyen, head of the European Commission, plans an expert panel to suggest child protection rules as she said parents are overwhelmed by the "tsunami of big tech." In the UK, no ban has been ruled out; any move will rely on strong evidence. The Molly Rose Foundation warns an age ban alone may push teens to unsafe platforms once they turn 16. Campaigner Beeban Kidron said the Australian ban challenges tech firms to make their services safer or keep children off. The UK government will watch how its new Online Safety Act impacts child safety. In the US, states like Utah, Florida, Virginia, Georgia, Tennessee, and Louisiana have passed various laws to restrict underage social media use or require parental consent. Yet a nationwide ban seems unlikely due to political gridlock. Senator Ted Cruz and others proposed banning under-13s from social media and restricting targeted content for under-17s, but the bill has stalled. Former Meta engineer Arturo Béjar told The Guardian that broad action is slow despite bipartisan support. Meanwhile, Malaysia will ban social media for under-16s starting next year, and Brazil raised Instagram’s minimum age. UNICEF warns social media bans can backfire, emphasizing that platforms also help isolated children and that tech firms must actively improve safety. Still, government actions show the world is acting more decisively on children's online risks.
