As a lunchtime PB&J enthusiast, this bit via Ezra made me smile:
Each time you have a plant-based lunch like a PB&J you'll reduce your carbon footprint by the equivalent of 2.5 pounds of carbon dioxide emissions over an average animal-based lunch like a hamburger, a tuna sandwich, grilled cheese, or chicken nuggets. For dinner you save 2.8 pounds and for breakfast 2.0 pounds of emissions.
Those 2.5 pounds of emissions at lunch are about forty percent of the greenhouse gas emissions you'd save driving around for the day in a hybrid instead of a standard sedan.
Would you give up a meaty lunch to reduce your carbon footprint?
