A Journey of No Return, Not a Circular Economy

By Herman Daly

The economic process is not a mechanical analog that can be run forward and backward, nor a circular process that can return to any previous state. Rather it is an irreversible and irrevocable process moving in the direction of time’s arrow of increasing entropy [1]. Finitude and entropy guarantee that the economic life of our species will be a journey of no return. Therefore even a stationary economy, in the classical sense of constant population and constant capital stock, is ultimately a journey of no return, because the metabolic throughput of matter and energy required to maintain constant stocks of people and physical capital, in the face of depreciation and death, is an entropic flow from ever less concentrated sources to ever filling sinks – and both sources and sinks are finite.


Time to Stop Worshipping Economic Growth

by Brent Blackwelder

There are physical limits to growth on a finite planet. In 1972, the Club of Rome issued their groundbreaking report—Limits to Growth (twelve million copies in thirty-seven languages). The authors predicted that by about 2030, our planet would feel a serious squeeze on natural resources, and they were right on target.

In 2009, the Stockholm Resilience Center introduced the concept of planetary boundaries to help the public envision the nature of the challenges posed by limits to growth and physical/biological boundaries.
