Animal genetic resources for food and agriculture assessments of livestock biodiversity: "The State of the World's Animal Genetic Resources for Food and Agriculture" (2007) and "The Second Report on the State of the World's Animal Genetic Resources for Food and Agriculture" (2015). Although many diverse species and breeds of animals are currently available for food and agricultural production, there is more work to be done on classifying their risk of extinction: in 2014, 17% of the world's farm animal breeds are at risk of extinction and 58% are of unknown risk status, meaning that the problem may be underestimated. The world's pool of animal genetic resources is
