During the past decade, he became aware of the role our diet can play and realized that a wholesale change to a plant-based diet could reverse global warming. I share Oort’s conviction that converting to a plant-based diet is an important and overlooked element of controlling global warming. Finally, a plant-based diet increases the absorption of calcium and bone metabolism, which helps with the formation of new bone tissue. Most of the environmental benefits of converting to a plant-based diet were included in Oort‘s presentation, with two notable exceptions. John Robbins’ 1987 book “Diet for a New America” noted that a plant-based diet has a water footprint of 300 gallons; a vegetarian diet requires 1,200 gallons; and a meat-based diet 4,000 gallons.
