The Bristol event is part of a series of UK wide and international days of protest as students and school pupils across the world miss classes, striking to protest a lack of governments' action to combat the climate crisis. School students around the world have gone on strike to demand action on climate change. Organisers expect more than one million young people to join the protests in at least 110 countries on Friday 24 May. The international movement was started by Swedish student Greta Thunberg and led to various movements across Europe, the US and Australia, known as Fridays for Future or School Strike for Climate. The last co-ordinated international protest took place on 15 March, with an estimated 1.6 million students from 125 countries walking out of school. Photo credit: Simon Chapman/LNP.
