Between now and 2050, a global switch to diets that rely far less on meat and far more on vegetables, fruits, and other plant foods could not only save up to 8 million lives per year, and reduce food-related greenhouse gas emissions by two-thirds. Such a change would also save, in reduced health care costs and reduced costs from climate change, up to $31 trillion.
Does that sound like the wild-eyed claim made by some group with a vegetarian agenda? It’s actually the conclusions of a major new study published in the Proceedings of the National Academy of Sciences of the United States.
