Students from around the world walked out of their classrooms Friday to protest what they call global inaction on climate change.
This is video of one such protest in Wellington, New Zealand.
In all, tens of thousands of students in more than 100 countries and over 1,500 cities and towns participated.
Protesters say governments worldwide are failing future generations by not tackling climate change.
They’re calling on leaders to cut emissions and curb global warming.
But not everyone is supportive of the strikes.
Critics say the students are naive and misguided, arguing they should be in school learning how to tackle climate change rather than protest.
An Australian education minister warned last month that students and teachers face punishment if they strike during school hours.
