Wild mammal biomass has declined by 85% since the rise of humans. But we can turn things around by reducing the amount of land we use for agriculture.

What are the carbon opportunity costs of our diet? How much carbon could we store by regrowing forests and wild habitats on existing farmland?

Estimates of food emissions can range from one-quarter to one-third. Where do these differences come from?
