Students ask adults to join them in Strike 4 Climate

School Strike 4 Climate organsiers are calling on everyone today - not just students - to join them on their third march. More than 40 events are being held across the country, and dozens of businesses and organisations across the country are promising to shut their doors and take part. Organisers Luke Wijohn and Sophie Handford tell Corin Dann they're hoping the march will be the biggest yet.
