In contrast to diets that were meat-heavy, the Oxford study showed a vegan diet reduced land usage by 75 percent, water use by 54 percent, and cut the loss of precious biodiversity by 66 percent. A vegan diet was considered to be one that avoided meat, dairy, eggs, and all animal products more generally. The effects of a vegan diet didn’t stop at positive environmental impacts. It was also shown that removing animal products from one’s diet could save 8.1 million lives by cutting the consumption of meat, eating more vegetables and fruits, and lowering obesity rates. On a global scale, diets that are higher in meat and lower in vegetables and fruit carried the largest negative health impacts.
Whether you reduce meat consumption or commit to the greatest net impact by eliminating animal products altogether, the takeaway from this study is clear: Eating less meat equates to a healthier planet and you. At Barn, we’d add that it leads to a happier Mike, Little Dude, and Harper when we cause less suffering to their friends who are victimized by the current food system.
