´óÏó´«Ã½

Phones have become an essential part of most people’s everyday lives, and debates about them in schools - as well as teenagers’ access to social media - are internationally hot topics.

´óÏó´«Ã½ journalist Hayley Clarke joins us in the studio to talk through different approaches to social media and phone bans in schools around the world. We also hear from students in France and the US about how they would feel about potential bans.

Hannah Ritchie, a ´óÏó´«Ã½ journalist, explains the situation in Australia, where the government says it will introduce "world-leading" legislation to ban children under 16 from social media.

Plus we hear from two professors on opposing sides of the debate, and ask what is the scientific evidence that shows phones and social media are bad for us?
