Not long ago, the English writer Robert MacFarlane, a true authority on nature non-fiction, published a book titled Are Rivers Alive? —available in Catalan through Angle— where he raised the possibility, studied by him and other environmental writers and activists, of treating elements of nature as living beings, and thus opening an infinite field of new questions and possibilities: what should this treatment be like? Do they have rights and duties? Can we protect them with laws, as we do with vulnerable groups? They certainly have a birth and a death, and they have been on Earth for several millennia, long before us as a species.
