Ignoring Uncomfortable Knowledge

Preface

There's a popular term, the "circular economy", making the rounds in the economic arena and in the halls of policy making... especially in Europe, a region in the forefront of the search for sustainability.  Proponents of the circular economy appear to be on the cusp of finalizing a concept which seems to provide a solution to the vexing problem of saving the ecosphere, the technosphere, the economies of the world, and society in general.  As my father used to say, however, "Hold your horses... not yet.".

Uncomfortable Knowledge

While the "circular" economists acknowledge the dependence of the economy on biophysical elements/flows, they simultaneously ignore the fact that those same elements are subject to thermodynamic constraints.  Their solution to any problems encountered is to:  1) "decouple" the economy from natural resources;  and, 2) to rely on technology, human genius, and the magic of the Market to do so.  In part, such thinking is based on the following.

The agricultural "Green Revolution" increased world food production exponentially in the late 1960's.  That was due mostly to the development of high-yielding cereal grain crops, and from the petrochemical industry, the development of synthetic fertilizers, insecticides, and herbicides.

In addition to the concept of entropy, the uncomfortable knowledge being ignored by proponents of the circular economy are the following facts.
1)  Agricultural and urban/suburban runoff of synthetic nitrogen fertilizers has caused massive eutrophication of bodies of fresh water, thus depleting them of oxygen and essentially killing all life in them.
2)  Synthetic pesticide use has had disastrous results over the decades on both nonhuman and human life.
3)  Synthetic fertilizers have caused a significant negative impact on soil structure, resulting in increased soil erosion in many places.

In other words, using the ag green revolution to encourage reliance on technology, human ingenuity, and the Market to solve social-ecological problems is not a good idea.  It totally ignores the downside of that revolution, and all the downside is not even fully known yet.

Conclusion

It seems to me that mainstream/neoliberal economists are attempting to repackage their economics as even more "circular" than before, and now "green" as well.  The problem is that they're still promoting unlimited growth and overconsumption.  Meanwhile, our life support systems on Spaceship Earth continue to be negatively impacted.  The "new" circular economy being proposed will not stop that.  And by the way, tick-tock.  Time is getting short.
