SCHOOL film makers across North Devon are being offered a chance to go national with their messages of climate change and sustainability Play it Cool, the North Devon climate change awareness project, has joined North Devon and Torridge District Councils and Northern Devon Coast and Countryside to set up a film competition for local secondary school groups. The aim is to make a film about climate change or sustainable living that can be used to help raise awareness with a variety of audiences. Brigit Strawbridge, from the television series It's Not Easy Being Green, is one of the judges and is offering the top team of student film-makers the chance to go national. She is keen to use the winning film for her next venture: a sustainability bus. She will travel around the country with a double-decker sustainability roadshow visiting schools and communities.
