There's no such thing as Sustainability

The Biosphere is a superset of dynamic systems.

Sustainability is not some fixed state that we achieve and then maintain forever.

Not least because definitions of sustainability are too vague to manage.

But because, even a sufficiently precise measure of sustainability aims to manage a system that is too complex to be managed.

There are simply too many moving parts, too many competing incentives, too many players and too many new arrivals.

From Designing Regenerative Cultures, by Daniel Wahl:

Sustainability is a dynamic process of co-evolution and a community-based process of continuous conversation and learning how to participate appropriately in the constantly transforming life-sustaining processes that we are part of and that our future depends upon.

But this does not mean we cannot live sustainably within the Biosphere.

In fact, we must do so.
