It was only with the rise of capitalism over the past few hundred years, and the breathtaking acceleration of… — Jason Hickel

In the absence of more consumers, capital finds ways to get existing consumers to consume more. Indeed, the dominant story for the past few hundred years: the growth rate of material use has always significantly outstripped the growth rate of the population.

is not about reducing GDP. It is about reducing the material and energy consumption throughout the economy to bring it back into balance with the living world, while distributing income and resources more fairly, liberating people from needless work, and investing in the publics goods that people need to thrive. It is the first step toward a more ecological civilisation. Of course, doing this may mean that GDP grows more slowly, or stops growing, or even declines. And if so, that's okay, because GDP isn't what matters. Under normal circumstances, this might cause a recession. But a recession is what happens when a growth-dependent economy stops growing. It's a disaster. Degrowth is completely different. It is about shifting to a different kind of economy altogether – an economy that doesn't need growth in the first place. An economy that's organised around human flourishing and ecological stability, rather than around the constant accumulation of capital.

Of course, we also have to think about the role of population going forward. The more the , the more difficult this challenge will be. As we approach this question, it's crucial - as always - that we focus on underlying structural drivers. Many women around the world do not have control over their bodies and the number of children they have. Even in liberal nations women come under heavy social pressure to reproduce, often to the point where those who choose to have fewer or no children are interrogated and stigmatised. Poverty exacerbates these problems considerably. And of course capitalism itself creates pressures for population growth: more people means more labour, cheaper labour, and more consumers. These pressures filter into our culture, and even into national policy: countries like France and Japan are offering incentives to get women to have more children, to keep their economies growing.
