This Special Issue of the Journal of Human Rights and the Environment revisits Professor Christopher D Stone's iconic 1972 article, and features an introduction by Professor Philippe Sands QC, a set of elegant and thought-provoking reflections on the original article by Baroness Mary Warnock, Professor Ngaire Naffine and Professor Lorraine Code, and an equally elegant and thought-provoking response to their reflections from Professor Stone himself. This thoughtful collection of essays will be a valuable addition to contemporary debates concerning the crucial search for new relationships between humanity and the living world and between human rights and the environment. The renowned contributors offer rich reflections on questions of legal standing, legal subjectivity and epistemology raised by Stone's article, and which have greater salience than ever as we face the environmental and human challenges of the 21st century.
