A .gov website belongs to an official government organization in the United States. If youre interested in taking the plunge, a vegan diet does have the smallest climate footprint around. Researchhas also foundthat minimally processed vegetarian foods have among the lowest environmental impact. Because optimal food production requires specific conditions (for example, certain crops or pests may thrive in a narrow band of temperatures), disruptions to environmental conditions can negatively affect crop yields, the nutrient content of crops, and the broader ecosystems that support food production and livelihoods . What about all the resources and energy needed to make all the ingredients in ultra-processed food? 2023 Scientific American, a Division of Springer Nature America, Inc.

Watch on Climate change is likely to diminish continued progress on global food security through production disruptions that lead to local availability limitations and price increases, interrupted transport conduits, and diminished food safety, among other causes. There are few things in life that make us quite so happy as food - and a tasty burger can do a lot to boost your mood. Almonds require a lot of water to grow, and this has been a problem in places like California.

(2020). An earlier version of a graphic accompanying this article about the average greenhouse gas impact of various foods included a value for milk that was based on a different measurement than the other foods. The environmental impacts of ultra-processed foods low or high arent the only factor to consider. An official website of the United States government. Some scientists are even trying to figure out how to get cows to emit less methane by introducing seaweed or other feed additives to their diet. But buying minimally processed food such as dried fruit, sliced or frozen vegetables or pre-cooked rice might actually result in fewer emissions than buying unprocessed fruit and vegetables and adding in this step at home. But even eating more plants, and less dairy and meat, particularly red meat, can help: According to a World Resources Institute analysis, if the average American replaced a third of the beef he or she eats with pork, poultry or legumes, his or her food-related emissions would still fall by around 13 percent. U.S. In the US, agriculture accounts for nine percent of GHG emissions. Rice production, for example, leads to high levels of methane and nitrous oxide both potent greenhouse gases being emitted into the atmosphere. Food production, processing, and availability also can affect community-level measures, such as economic growth and social infrastructure. His co-author Xiaoming Xu, also at the University of Illinois at Urbana-Champaign, is optimistic about the prospects of making a dent in food-based emissions.
