Students hold a banner during a 'Fridays for Future' demonstration against climate change in Berlin, Germany on March 29, 2019. Students across the world are taking part in a strike movement called #FridayForFuture which takes place every Friday. The movement was sparked by Greta Thunberg of Sweden, a sixteen year old climate activist, who has been protesting for climate action and the implementation of the Paris Agreement outside the Swedish parliament every Friday since August 2018.
