This fun, easy-to-use calculator starts with an easy question, “Do you eat food?” Then it gets more specific about which foods you eat, and what you do with leftovers. In the end, you’ll have a better understanding of how what you eat affects the climate. (Note: The third question starts with, “If there’s room on my plate …”. Use your cursor to slide the red dot along the scale. Some test-takers find this confusing).
