An enduring and topical picture book about the threat of pollution to our environment.

On the beach, a brother and sister create their own tiny marine world in a bucket. With its wildlife, shells, oil and even a tin can, it is a microcosm of the larger world outside; a world polluted by ocean plastics, deforestation, and the burning of fossil fuels.

With a series of stunning watercolours, the multi award-winning Michael Foreman makes clear his underlying concern about pollution within the environment. 30 years since it was first published, One World is more relevant with every passing day.
