For years, we’ve heard that eating less meat, especially beef, can positively impact the climate. Now, a new analysis led by Matthew N. Hayek from New York University suggests that even modest cuts in beef production in wealthier nations could have a significant effect. The study finds that by focusing on specific grazing lands, we could reforest low-productivity cattle pastures, absorbing billions of tons of carbon dioxide in the process. “We can achieve enormous climate benefits with modest changes to the total global beef production,” says Hayek. The study, published in Proceedings of the N…
