Today, we take a little bit of break from talking about science to instead talk about how media covers science, particularly the reporting on genetically modified organisms (more commonly called GMOs). It’s a contentious subject, and Keith talks about why people tend to take it so personally, when he got interested in GMOs, and what caused him to become the “crop cop.”
Humans have always been changing the earth’s surface, but the study of land use change has been greatly aided by satellite imaging since the 1970s. Professor Eric Lambin started his career working with satellite images to examine patterns of land change, and emphasizes that understanding the patterns requires going into the field and talking to the farmers and locals using the land. He also discusses how globalization and international trade can drive land use change in unexpected ways. Finally, Professor Lambin explains the concept of potentially arable cropland (PAC) and the relevance of “peak land” in the context of the Anthropocene, especially for policy makers.

Ten years ago I walked away from college thinking, “The planet is screwed, we’re all screwed. Or, at least I think we’re screwed. But wait…are we really screwed? Maybe not. Shoot, I don’t know. I don’t have enough information here. I’ll go back to school.” Continue reading
