Abstract The recent edition of the Red Book of Endangered Brazilian Fauna brings 1,173 threatened species, 86% of them in terrestrial or freshwater environments. For these species, the main threat vector is agricultural activities that affect 519 species (51%). This information brought by the Red Book is examined in-depth and its consistency is discussed in search of an objective view on the impacts of agriculture, its importance, how they affect the different groups of animals, the different biomes of the country, and the different types of habitats continental. Birds, fish, and invertebrates are the groups with the highest number of species threatened by agricultural activity, accounting for more than 70% of the species. Habitat loss is by far the biggest impact caused by the activity, affecting almost 90% of the species. However, there is a difference between the impact of agriculture and livestock. The work seeks to understand why livestock threatens a smaller number of species, although pastures occupy more than twice the area occupied by crops and forestry. The work brings an objective debate on the relationship between agricultural activities and the conservation of wild fauna in Brazil, without falling into the trap of the useless demonization of human activities, highlighting, instead, the need to define and implement strategies for the conservation of biodiversity in the midst the land use matrix itself, complementary to the conservation units, based on the best available information on the vulnerability of fauna to the impacts of this vector.
