Thank you. Yes, they do. But they are pretty inefficient manure factories [https://ourworldindata.org/grapher/land-use-kcal-poore https://ourworldindata.org/grapher/land-use-kcal-poore]. We even have 8 milliards of humans producing manure, which we currently (mostly) flush to the sea [https://en.wikipedia.org/wiki/Night_soil https://en.wikipedia.org/wiki/Night_soil]. And if we do use it, we do it wrongly [https://www.theguardian.com/environment/2022/mar/22/i-dont-know-how-well-survive-the-farmers-facing-ruin-in-americas-forever-chemicals-crisis https://www.theguardian.com/environment/2022/mar/22/i-dont-k...]. We have to learn how to use what we have (atmosphere, rhizosphere, pigs, poultry, humans), that what does not destroy forests and wildlife (cows), and avoid that that kills and poisons the nature (pesticides & herbicides). Then we have a chance.
