What’s the best way to reduce your carbon footprint? A new influential study recently published in Science says: Go vegan.

The study is described as “the most comprehensive analysis to date of the damage farming does to the planet.” To come to their conclusions, the authors J. Poore and T. Nemecek looked at data covering nearly 40,000 farms and 16,000 processors, packagers, and retailers. This means they studied the impact of the meat and dairy industry, from the bottom up, rather than the previous top-down approach using national data, which is why this study is so profoundly revealing. In doing so, they determined that without meat and dairy consumption, we could reduce global farmland use by more than 75% and still feed the world.

This conclusion rests on their finding that livestock uses 83% of all available farmland and produces 60% of all greenhouse gas emissions, yet meat and dairy consumption provide only 18% of our calories and 37% of protein. Based on this study, it seems that eliminating meat and dairy consumption from our diets is the best way to reduce our environmental impact. According to Joseph Poore, at the University of Oxford, UK, who led the research: “A vegan diet is probably the single biggest way to reduce your impact on planet Earth, not just greenhouse gases, but global acidification, eutrophication, land use and water use. It is far bigger than cutting down on your flights or buying an electric car,” as these only cut greenhouse gas emissions. Continue reading →
