Hi Hugh,
Living in such a lovely part of the country has many benefits, but it must be heart breaking to see the impacts of coastal erosion over the years. The severe weather events we are experiencing must be eroding some of the beautiful terrain there. In terms of drawing awareness to it in primary schools, there is potential to show some old images of certain landmarks and visit them today in a ‘compare and contrast’ activity. Giving children the concrete evidence of changes that have happened/are happening in their area can be powerful. The beach clean up is a great idea in your area, and you could incorporate other lessons and learning while you’re there!
