By 2040, it’s estimated that 9 billion people will call Earth home. And how the planet will feed all of those mouths is a concern. This hour, we’ll meet the agricultural scientists who are creating more sustainable wheat, growing meat in labs and even developing 3D printers that could one day produce food. We’ll be joined by Jayson Lusk, chair of the department of agricultural studies at Oklahoma State University and author of “Unnaturally Delicious: How Science and Technology are Serving Up Foods to Save the World” (St. Martin’s Press).
