Thousands of students have taken to the streets of towns and cities across the West Country to call for action on climate change.
In Exeter, the chant was loud and clear - "Save our planet it's not too late."
Researchers for the United Nations say the earth is in crisis - with global warming and species facing extinction due to the loss of habitats. But they say it is not too late to act - by reducing harmful emissions for example. The UK Government declared a climate emergency earlier this month but the Youth Strike 4 Climate movement says action is needed urgently.
George Bond from Exeter says politicians and people in industry need to work together for change.
One campaigner from Bath said protests like this are the only way young people can get their message across.
In Bath they held a mock funeral march to highlight the urgency of the crisis, using a coffin to hand their demands to the council.
In Cheltenham the striking students marched from Montpellier Gardens into the town centre, before finishing at The Prom, in an effort to get people to increase pressure on Parliament to take action on climate change.
In Bristol, the protests were focused on the expansion of the city's airport. The owners claim increased capacity will mean fewer road journeys as more people will fly locally. But the campaigners say there's no way to justify expanding an airport.
In Barnstaple, a hundred young people took to the streets at lunchtime with a clear message for change. They held home-made banners high as they made their way to hand in a petition at the offices of North Devon Council.
