Correction to: Nature Food https://doi.org/10.1038/s43016-022-00661-1. Published online 15 December 2022.

In the version of this article initially published, there was an error in the caption of Fig. 1c, now reading “Cropland area required to produce per unit of monogastric protein,” where “monogastric” replaces “ruminant”. In the caption of Fig. 1b, now reading “(1) manure deposited on other grassland (12 Tg); (2) manure applied to croplands for human nutrition or feed for other animals (37 Tg)”, “12 Tg” and “37 Tg” replace “11” and “39,” respectively. The changes have been made in the HTML and PDF versions of the article.
