Most of Earth's terrestrial carbon is stored in the soil and can be released as carbon dioxide (CO 2 ) when disturbed. Although humans are known to exacerbate soil CO 2 emissions through land‐use change, we know little about the global carbon footprint of invasive species. We predict the soil area disturbed and resulting CO 2 emissions from wild pigs ( Sus scrofa ), a pervasive human‐spread vertebrate that uproots soil. We do...
