This global study highlights the importance of addressing the entire food system and its potential to contribute to greenhouse gas mitigation. It also shows that global studies, while useful in addressing these issues, cannot enter into the complexity of cycles as complex as those of biogenic CH4. These cycles have natural and anthropogenic components, which interact in complex ways that we have yet to delve into to guide action. For all these reasons, the conclusions of this article should be viewed with caution, taking into account the simplifications involved in this type of study.  

I would like to highlight the work of Costa et al., published in September 2022, which offers a complementary vision that explores some very relevant aspects that help to understand the complexity of the issue.
