Did you know how much a peanut butter and jelly sandwich can change the world? Check this out!
From the website of the Peanut Butter & Jelly Sandwich Campaign:
A PB&J will slow global warming. Next time you have one you'll reduce your carbon footprint by saving 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. That's about forty percent of what you'd save driving around for the day in a hybrid instead of a standard sedan. If you were going to have a ham sandwich or a hamburger, you save the equivalent almost 3.5 pounds of greenhouse gas emissions.
