Thousands and thousands of protesters, many of them students who skipped school, have gathered in cities across the world kicking off a day of worldwide protests calling for action against climate change ahead of a United Nations summit.
From the Pacific Islands to Australia and India, protesters took to the streets on Friday, demanding their governments take urgent steps to tackle the climate crisis and prevent an environmental catastrophe.
Greta Thunberg, the 16-year-old Swede who inspired the climate strike, tweeted her support.
