00:00 What is the common point between ecology, economy and a donut?
00:04 The shape, the circular shape...
00:06 But in fact, it's much more than that.
00:08 It's an economic theory that would allow humanity and the environment to flourish without having to walk on it.
00:14 Let me explain.
00:15 This theory is the donut theory.
00:17 It's a concept that was developed by the British economist Kay Travers.
00:22 This concept, which she details in this book, explains how to meet human needs while preserving the limits of the planet.
00:28 Look. This part inside represents our needs, humans' needs.
00:32 Food, education, water, etc.
00:35 If we cross this limit, we deprive humans of their vital needs and we fall into the hole.
00:40 This ring is the limits of the planet to not cross.
00:43 Climate change, pollution, warming of the oceans, etc.
00:47 Same thing, if we cross the border, we risk causing irreparable damage to the planet.
00:52 Basically, according to Kay Travers, we should change compass and aim for the inside of the donut,
00:58 the intermediate space with a stationary growth that would meet human needs while preserving the planet.
01:05 For now, in the world, no country really respects this virtuous circle.
01:09 But some cities are inspired by it.
01:11 This is the case of Amsterdam, the capital of the Netherlands, which develops, for example, collective agriculture projects
01:16 or which recycles computers to give them to people who don't have any.
