Innovative project uses salt marsh to protect coastline from sea level rise

Salt marshes in the Fraser River delta are a vital ecosystem for birds and other wildlife. But they are being squeezed between the dykes that protect farmland on one side, and sea level rise on the other. An innovative pilot project aims to protect the salt marsh so that it can, in turn, protect the low-lying land along the coast. We talk about the project with Sḵwx̱wú7mesh journalist Stephanie Wood.
