When you crunch the numbers, a plant-based diet always wins. Here's more proof.
Gidon Eshel was born in Israel on a kibbutz and, as a kid, he worked on a dairy farm there. He then did the appropriate time in leafy New England universities and became a geophysicist, whose work has focused on quantifying the Mean American Diet with complex mathematical formulas. He joked that he's 80 percent numbers and 20 percent farmer.
At last year's PopTech conference, Michael Pollan suggested that "a vegan in a Hummer has a lighter carbon footprint than a meat eater in a Prius." While his pithy quote went viral, it was incorrect. And when Adam Pasick questioned the math, he called Eshel for a fact-check.
