Any report on mineral availability that starts with "a semi-infinite deposit" should be taken with great caution - it reminds of when Julian Simon said that we have oil for "six billion years". About this report on rare earths, I'd say that calling it "clueless" is way too kind.

Earth scientists have been making the case for years that the present level of human activity is not sustainable. We’re rapidly depleting resources, degrading ecosystems, altering the atmosphere, etc. What earth scientists are saying is generally not covered by the mainstream media, or is sugar coated, because the mainstream media is an outlet for the corporate perspective on the world.

Anyway, I have now read Dorling’s book and I want to share a few thoughts about it. They’re not in the form of a comprehensive warts-and-all review – rather, I want to highlight five themes of interest to me that anticipate some future posts, on which I think Dorling has thought-provoking things to say.

So, is mineral depletion an existential threat to human civilization? Or is it just a marginal problem that can be fixed by some technological improvements? This is truly a fundamental question for the future of humankind. An answer is provided by the latest report to the Club of Rome that was published in 2017, "The Seneca Effect."

We should recognize our limits, too. Follow change, don't try to stop it. Nature is changing all things we see and out of their substance it will make new things in order that the world will be ever new. This is the way Nature works.

Doughnut Economics, by Kate Raworth (Chelsea Green, 2017) is an interesting book that goes in the right direction in the sense that it promotes a circular economy, but it leaves you with the impression that it missed that extra step that would have lead it to define the goal in the right way. Bridging the gap between standard economics and biophysical economics is still far away.

We now have to take into account that depletion means that, at well heads around the world, the energy to produce energy is increasing. It takes energy to prospect for oil and gas and if the wells are smaller and more difficult to tap because, for example, they are out at sea under a huge amount of rock. Then it will take more energy to get the oil out in the first place.

So don't let a title like When Trucks Stop Running give you the impression that Friedemann's book is simply one about the energetic options for the trucking industry, since what it actually does is use trucks as an interesting starting point for how to understand the viability of the various energy options available to our declining industrial way of life.

A report on the world’s oil depletion problem published several years ago by an obscure association of anonymous consulting engineers and professional project managers is suddenly coming under fierce criticism.

...[A]n unfortunate side-effect of the explosion of information that the Internet has provided us with is the even further erosion of the signal-to-noise ratio.
