World Water Day on March 22 is intended to be a celebration. Yet, for many in the UK, it brings up images of rivers and beaches contaminated with raw sewage, with 450,000 discharges recorded in England in 2024. It’s become a major political scandal, and is now the subject of a bleak Channel 4 docudrama.

But what if rivers themselves could take legal action against this pollution?

A growing movement of campaigners and researchers say rivers should be granted their own rights, independent of their value to humans. In this framework, rivers are not just resources to be used, but entities with the legal right to flow and to remain unpolluted. Crucially, those rights could be enforced in court by designated human guardians. Advocates of these “rights of nature” say it could give rivers a powerful new way to challenge pollution.
