Like biographies use their subject as a prism for the world around them, I use data centers as a prism for much larger but invisible environmental problems, hidden by our tendencies toward populism and localism that data centers offend. This post focuses on the ridiculous ways we use land in America, which (like most of our water issues) is downstream of farmers being shielded from popular criticism by political alliances and folk intuitions about the honest toil of growing food. By the end, I hope you’ll be much more skeptical of headlines like this:

and of the idea that data centers purchasing farmland is a unique evil.

I’m not claiming data centers should be built anywhere and everywhere. There are lots of places where they’ve been built too close to people’s homes. This post is about whether data centers waste the land they’re on relative to what they compete with, and my claim is that they mostly don’t compete with things we need more of (housing) and mostly compete with things we need less of (farmland).
