Over at the Conversation, a couple of academics are trying on the whole "we're going to run out of phosphorus" malarkey again.
How the great phosphorus shortage could leave us short of food
This has been so thoroughly debunked so often that you'd think that nobody would want to risk it again, but it seems there is no limit to the foolishness of the eco-academic.
I think what they are actually trying to say is that they have invented a process to recycle a mineral. Unfortunately that mineral is cheap and abundant and nobody is interested in their work. But they'd quite like someone to invest in it anyway.
What a way to spend your life.
