Students and supporters join School Strike 4 climate protests

Students and supporters in Auckland, New Plymouth and Christchurch swapped their books for picket signs as they joined the School Strike 4 climate protests today. They're calling for the government to uphold commitments to the emissions reduction plan, stopping oil and gas exploration and lowering the voting age to 16. But as Ashleigh McCaull reports, crowd sizes are a lot smaller compared to previous strike action.
