For climate conscious eaters, beef has become the food to avoid. That’s largely thanks to its outsized climate footprint of factory farmed beef, which contributes more greenhouse gases per serving to the atmosphere than almost any other food. More than half of that impact comes from methane, a greenhouse gas that’s about 25 times as potent as carbon dioxide in terms of warming the earth. Most climate experts seem to agree that reducing consumption of factory farmed beef is one of the most important shifts that developed countries can make to combat the climate crisis.
