Depleting the Soil--It's Not Astrophysics

This post at Time/World beats the drum about our broken food system:
some experts fear the world, at its current pace of consumption, is running out of useable topsoil. The World Economic Forum, in collaboration with TIME, talked to University of Sydney professor John Crawford on the seismic implications soil erosion and degradation may have in the decades to come.

Prof. Crawford has this background: "John Crawford was awarded the prestigious Judith and David Coffey Chair in Sustainable Agriculture at the University of Sydney in 2008. He holds a BSc in Physics from the University and Glasgow and a PhD in Theoretical Astrophysics from the University of London."

I'm being a bit hard on him.
