The Dublin Declaration on the Societal Role of Livestock Farming encouraged scientists in the field to alert policy-makers and the public to the importance of basing dietary recommendations and promoting an image of livestock farming on sound scientific evidence. They do this conscientiously, even if they become the target of militant campaigns aimed at discrediting disturbing scientific voices. Certainly, divergent views have been expressed on the best way to implement scientific findings, or on the optimum nature or size of future livestock systems. However, there is a firm consensus on the crucial importance of maintaining rigorous scientific approaches for an informed debate on livestock farming. This context prompted animal scientists to renew their commitment by publishing the Denver Call to Action. This was done on the occasion of the second International Summit on the Societal Role of Meat and Livestock in Denver in October 2024, where scientific knowledge about livestock farming was presented. This call is addressed to political decision-makers around the world to commit to plurality and rigor in evidence-based decision-making. Meeting the colossal challenge of feeding the world's populations while minimizing environmental damage will only be possible through the transparent application of scientific rigor, avoiding hubris, presumption and dogmatism.
