Evidence of the extent of the world’s plastic litter problem is washing up on Guernsey’s beaches with every tide.

But it does not go unnoticed. It is being removed and catalogued. A group of Guernsey beachcombers, united under the Facebook group Found on the Beach in Guernsey, “womble” across the island’s bays on a daily basis and share their evidence with the marine biologist Richard Lord.

He cleans, reinflates and collects plastic water bottles, along with other kinds of waste, in his garden shed at his St Peter Port home, less than half a mile from the sea.
