What did you last eat? And why? Don’t worry, we won’t tell anyone. After all, it’s not entirely up to you.

The food that ends up on our plate is the result of global trade dynamics, cultural norms, seasonality, marketing, thousands of years of plant breeding, and personal tastes. And it’s all constantly changing. In this episode, we discover how nutrition evolves over time, and how crop science keeps up.

In this episode, we talk to a wide range of guests about the innovation that drives vertical farming, the sustainability challenges it addresses, and the advances in plant breeding that could take large-scale indoor agriculture into the mainstream.

Sustainability is in the news, it’s in our politics, it’s in our hamburgers. And, of course, it’s on our farms. But how does the sustainability conversation sound around the world? Sustainability seems to be everywhere. In episode three, we talk to those making sure it works for everyone.

Our first three episodes explored the changing climate, the digital revolution, and our fluid understanding of what “sustainability” really means—and requires. The common thread? Change may just be the most consistent thing in human history.

“The Digital Revolution.” You’ve heard of it. Everyone has, perhaps so many times that the words have lost their meaning. But the advent and explosion of the Internet — and the way it has transformed the way we live, work, and even eat — is no less remarkable.

We contribute to climate change every day by emitting carbon dioxide. But some of us have chosen to farm it. New technologies and agricultural practices are helping farmers devise new solutions for climate change.
