We are living on ecological credit, drawing down the stock of natural capital while our overall consumption exceeds the planet’s ecological limits. As with an increasing bank overdraft, this cannot go on forever: it is clear that a step change is needed.
One planet thinking and the Doughnut Economy Humanity’s 21st century challenge is to meet the needs of all within the means of the planet. In other words, to ensure that no one falls short on life’s essentials (from food and housing to healthcare and political voice), while ensuring that collectively we do not overshoot our pressure on Earth’s life-supporting systems, on which we fundamentally depend – such as a stable climate, fertile soils, and a protective ozone layer. The Doughnut of social and planetary boundaries is a playfully serious approach to framing that challenge, and it acts as a compass for human progress this century.
