The South West Coast Path and the South Dorset Ridgeway are ancient trails that stretch from Dorset in the east to Cornwall in the far southwest of England. For millennia these natural elevated byways have been critically important to local people. With expansive views across the Jurassic landscape to the sea beyond, these highpoints still evoke the ancient communities who used them as vantage points. Even in these protected landscapes human impact can be seen everywhere. Plastic on the beaches, nets on the shore, dead seabirds and fish, farm runoff and sewage outflows, moving from land into rivers and from rivers to the sea. Ebb and Flow acts as a A stark reminder of the climate emergency. The images foreshadow the ecological concerns of climate change against an ancient natural world teetering on the edge.
