Some of us have a different view. From our minority perspective, the global economy as currently configured is inherently not just unstable, but unsustainable. The economy depends on perpetual growth of GDP, whereas we live upon a finite planet on which the compounded growth of any material process or quantity inevitably leads to a crash. The economy requires ever-increasing energy supplies, mostly from fossil fuels, whereas coal, oil, and natural gas are nonrenewable, depleting, and climate-changing resources. And the economy, rather than being circular, like ecosystems (where waste from one component is food for another, so all elements are continually recycled), is instead linear (proceeding from resource extraction to waste disposal), even though our planet has limited resources and finite waste sinks.
