Rivers as persons: What it means to give legal rights to nature

Erin O'Donnell
Julia Talbot-Jones

Environmental law researcher Erin O'Donnell and economist Julia Talbot-Jones explain what's behind recent moves to give legal personhood to rivers in India, New Zealand and elsewhere. With philosophical roots going back decades, new legal and legislative developments granting personhood to nature seek both to recognise indigenous or religious claims as well as provide new avenues for environmental protection. But what does this mean, and how will giving rights to nature be enforced? Can rivers now bring lawsuits, and can we, in turn, sue them? Presented by Lynne Haultain.
