I’m currently taking the free online class “An Introduction to the U.S. Food System: Perspectives from Public Health” at coursera taught by instructors at the Johns Hopkins Bloomberg School of Public Health. I’d recommend it to anyone interested in the topic; the lectures have been engaging and the resources plenty.
One of the exercises they had us perform is to use the Ecological Footprint Calculator to determine an estimate of the number of Earths it would require if everyone were to live the way we do.
