Changing food economies
I know the problem but not the solution. With a burgeoning world population, a rapidly advancing food technology (e.g., synthesising food rather than growing it), and our economy relying on inefficient meat and milk production, in the medium term we are going to be redundant as a food provider. Somehow, we need to begin a gradual switch away from meat and diary into more effective and non-polluting use of arable land.
