An exciting study by authors from the United States and the United Kingdom published in the Proceedings of the National Academy of Sciences in 2019 found a correlation between the most health-promoting foods being associated with the lowest harmful environmental impacts. The study's findings demonstrate One Health principles, correlating positive human health with conservation and preservation of the environment. The study also found that foods that are known to be disease-promoting, such as red meats and processed meats, have higher environmental impacts than fish, for example. However, there is still the concern of overfishing and reduction of biodiversity. Some of the harmful environmental effects associated with certain agricultural practices and animal production for food are greenhouse gas emissions, land use, depletion of water supplies, as well as acidification, and nutrient pollution of surface waters. 

Additionally, CDC One Health has a domestic and global mission to prevent the emergence of harmful zoonotic diseases. They provide education and resources, including laboratory expertise, to identify, contain, and prevent the spread of emerging infectious diseases. They even offer educational programs geared towards the youth. Working in the United States, One Health has also played a considerable role in the COVID-19 response.
