Why are Australia's school children on strike?

Across Australia, students are leaving school this week in protest against climate change. Hundreds lined up outside Parliament House on Wednesday wanting to speak to the Prime Minister Scott Morrison and government ministers about taking emergency action, even after the Prime Minister told them to stick to school.

One of the strikers is 17-year-old Maiysha Moin.
