A global food crisis may be less than a decade away | Sara Menker
October 5th, 2017, 07:30 PM
Sara Menker quit a career in commodities trading to figure out how the global value chain of agriculture works.

"People could starve and governments may fall." Menker's models predict that this scenario could happen in a decade -- that the world could be short 214 trillion calories per year by 2027. She offers a vision of this impossible world as well as some steps we can take today to avoid it.
