 You said it from the get-go. This is an image. And more than just words, we need images and we don't need to be against something, we need to be drawn into something else. So you have plenty of circles or donuts behind you as well. What is so attractive about this image? I even have one right here on the screen. The benefits of lockdown, right? You have everything on a stick. So the donut is like a compass for human prosperity in the 21st century. It's one way of envisioning the future of the world we want. So if you imagine humanity's use of Earth's resources, since we're here talking about metabolism, the use of Earth's resources radiating out from the center. It means the hole in the middle is a place where people are left falling short on the essentials of life. It's where people don't have the resources they need for health and education, food and housing, income, transport, connectivity, political voice and equality. Leave nobody in the hole. Fine. But as we bring everybody out of the hole, there's also an outer limit here. Don't go over this ecological ceiling because that is the way we collectively start to put so much pressure on this planet's life-supporting systems that we begin to kick our planetary home out of balance. That's where we cause climate breakdown and we acidify the oceans. We create a hole in the ozone layer. We cause critical loss of biodiversity and break down the web of life. So in the simplest of terms, the goal of the doughnut is to meet the needs of all people within the means of the living planet. And the first thing it does actually is transform the shape in our minds of what we think progress looks like. Because the 20th century told us in every economics textbook and every political speech and the pages of the newspapers, here we are, this was the shape of progress. You have all your props ready for it. I have all my toys. Hey, if you're going to be locked down in your office for a year, you might as well have some toys. So there's never-ending growth. It goes the ceiling off the screen, up through the ceiling. Nobody asks what happens when we hit the ceiling and go through. This was the shape of progress. And we need to transform that. And that's what the doughnut is part of. And as you just said, it's one thing to protest and critique what's wrong, what's wrong with the old, what's wrong with GDP, fine. But we're never going to transform the world by critiquing things. As Buckminster Fuller said, you never change things by fighting the existing reality, to change something, build a new model that makes the existing model obsolete. So I think of the diagrams that I was taught in my economics textbooks, I think of them like intellectual graffiti, very hard to scrub out. So stop scrubbing. Let's paint them over with an amazing mural of something actually better. And that's the power of pictures. They give us a new worldview. And that's what the doughnut aims to do. And I think when I first drew the doughnut diagram back in 2012, it was published in the run-up to the Rio Plus 20 conference on sustainable development. And so many people said to me, you know, I've always thought of sustainable development like this. I've just never seen the picture. And I could see that it was empowering to people to have a picture in the hand, to have something to point to, to feel that they could visualize this vision of the world they wanted to create. And that's what drove me to to leave my job at Oxfam and write the book as the most effective act of advocacy I could do at the time.
