PROTEIN FOOD CHOICES AND SUSTAINABILITY 355 • If you eat meat every day, try adding a “meatless Monday” into your week and experiment with some vegetarian recipes. Once you’ve adapted to that, try adding another day. • Replace some of your beef meals with dishes featuring chicken, pork, eggs, fish, or legumes. • Eat smaller portions of meat and add more plant foods to your plate. For example, if you enjoy spaghetti and meat sauce, try using less meat in your sauce and adding in vegetables like mushrooms, bell peppers, and carrots. Your meal will be more nutrient-dense and maybe even more flavorful. When you consider that moderate shifts like these would not only be good for the planet but also good for our health, then they don’t seem like much of a sacrifice. A 2016 study published in the Proceedings of the National Academy of Sciences concluded that just following standard dietary guidelines (which recommend a variety of protein sources, including plant proteins, and eating more whole grains, fruits and vegetables) could reduce mortality by 6 to 10 percent and cut greenhouse gas emissions by 29 to 70 percent. 3,4 This page from the World Resources Institute provides more information: Sustainable Diets: What You Need to Know in 12 Charts, by Janet Ranganathan and Richard Waite, April 20, 2016. ANIMAL AGRICULTURE AND ANTIBIOTIC RESISTANCE One of the biggest current threats to public health is antibiotic resistance. Antibiotics are life-saving drugs, but over time, bacteria can develop resistance to them. This means that the antibiotics no longer work to kill the bacteria causing infections, leaving people with more severe illnesses and fewer treatment options, often needing to try different antibiotics that have more side effects. There are now some bacterial infections for which we have no working antibiotics to treat them. According to the CDC, at least 2.8 million people are infected with antibiotic-resistant bacteria each year in the U.S, and these infections are thought to kill at least 35,000 people annually. 5 Addressing this problem will require us to be more careful about how we use antibiotics, invest in research to develop new ones, and to develop other ways of preventing bacterial disease, such as new vaccines. Antibiotics are important to both human and animal medicine. When we’re sick with a bacterial illness, we may need antibiotics to treat it, and the same is true of animals, whether they’re raised for agriculture or part of our families as our pets. The problem is that the more we use antibiotics, the more chances bacteria have to evolve resistance to them, and the less effective those antibiotics become.
