Ailton Krenak, born in the Doce River valley in Minas Gerais, is a member of the Krenak people and has become one of the main voices in defence of Indigenous peoples’ rights in Brazil. He has an ambitious plan: postponing the planet’s collapse. His book, Ideas to Postpone the End of the World, published in 2019, was an instant bestseller. Despite the title, the book is not a manual, and does not offer practical recipes for sustainable living. On the contrary, the revolution proposed by the author is even more radical, an inner revolution. Ailton proposes to live life radically, without compromise.
