Central to the case I want to make are a set of ideas and recent developments that are grounded in the notion of ‘natural capital’. The baseline of this approach is that, in and of itself, the natural world is priceless – but that doesn’t mean it doesn’t also have value. We are all familiar with the concepts of financial capital, human capital and social capital. Natural capital is simply a framework that can allow us to recognise a sliver of the value that we derive from the natural world: the ways in which our natural assets, like forests and oceans, can provide a range of ecosystem services that represent economic and social goods. These services range from tangible ones like clean air and water, carbon storage, fertile soils and pollination, to the intangible cultural and spiritual value that complements them. If we are to meet the imperative to protect and restore our planet, we can no longer treat nature as a distant wonder to be enjoyed on occasion before we retreat once again to modernity: natural capital fundamentally underpins our wellbeing and deserves a central place in our economic framework.
In an economy roiled by crisis after crisis, it can feel at times like the only option we have is to rip up our current system and start over again, embracing degrowth or dramatically curtailing the market economy. But the ‘market’ is a social construct, and one that has largely been governed with a narrow set of financial aims in mind. With time running out, I argue that we need to make a serious effort to fold nature’s value into the system we already have: one that has, to its credit, brought remarkable progress and improved living standards for many, but has clearly gone too far in the direction of environmental destruction.
