In the second half of the 20th century we got better at extracting the earth’s resources. Much better. So much better in fact, that for 40 years, despite demand for natural resources growing, the cost of those resources decreased. Not anymore. Since 2000, prices for the world’s natural resources have been steadily rising. The old linear model of business – take-make-waste, where profit depends upon managing resources in the production of products – is not only environmental suicide, it’s also business suicide.
