About 15 million lives could be saved annually with a shift to healthier, mostly plant-based diets. This insight comes from the EAT-Lancet Commission, a group of global scientists studying the link between food, health, and climate change. They emphasize that without serious reforms in our food systems, we can expect to see severe impacts from climate change, even if we switch to cleaner energy.
Johan Rockström, a key figure in the study and head of the Potsdam Institute for Climate Impact Research, warns: “If we don’t change the unsustainable food path we’re on, we will fail in many areas, including climate and food security.”
The first EAT-Lancet report in 2019 was groundbreaking for delving into food system reforms. The latest findings echo those original conclusions, suggesting that a “planetary health diet” consisting mainly of grains, fruits, vegetables, nuts, and legumes could lead to significant health benefits while also reducing greenhouse gas emissions. The recommendation? People should aim to limit red meat to about once a week, especially in developed nations.
The report indicates that dietary changes could reduce agricultural emissions by about 15%. This could increase to 20% with better crop management and reduced food waste. Interestingly, if wealthier nations adhered to the recommended limits on beef and lamb consumption, it would equate to cutting emissions equivalent to the total annual emissions of Russia.
Food choices are deeply personal, and small adjustments can make a big difference. Even reducing meat intake is a manageable step. According to Emily Cassidy from Project Drawdown, many people connect food to their identity, so even minor changes are valuable.
The EAT-Lancet researchers frame food systems as major contributors to environmental issues. Kathleen Merrigan, a professor at Arizona State University, praises the report for its thoroughness, revealing how interconnected issues like agricultural practices and consumption habits are.
While dietary shifts could cut down greenhouse gas emissions, a noteworthy challenge remains: nearly half of the global population struggles to access sufficient and healthy food. The report highlights that marginalized groups, including ethnic minorities and conflict-affected communities, face extra barriers in the food system.
As global leaders prepare for upcoming climate talks, there’s a hopeful call to action for them to integrate scientific insights about food systems into their policies. Failing to do so might lead to fragility, threatening both food supply and public health.
In trying times, our food choices can empower us to contribute to a healthier planet and safer communities. Staying informed and making thoughtful changes in our diets could be a step toward addressing these larger challenges. For more on how diet affects climate, visit the EAT-Lancet Commission.
The conversations around our food choices are gaining momentum, with more people discussing healthy eating on social media. Awareness is growing, and many are inspired to join the movement toward a more sustainable food future.
