Wheat feeds billions but it has some big climate problems. Wheat production degrades the soil, which releases carbon. It also requires a lot of land. That means clearing land—often forest—to make room for it, which also releases carbon. Plus, wheat harms ecosystems: fertilizer runoff causes water pollution, and monoculture hurts biodiversity.

One alternative? Kernza. Developed over decades by the Land Institute, it’s a perennial relative of wheat that sequesters carbon with its massive root system. But does its carbon-sequestering power make it truly climate-friendly?

This week, Mike and Tamar talk about Kernza and the decades-long movement to domesticate the holy grail of grains: a crop that not only produces high yields but also improves the environment.
