7. It Rubs Off on Your Family
Every family has its chef — the person primarily in charge of packing lunches, making weekend pancakes, and getting dinner on the table each night — and that’s the person who has the most influence over how the others eat. But just one severe food allergy in a family can change the eating habits of everyone else: You’re not just cutting out dairy for one person, but for three or four or five, which has a much bigger impact on the bottom line of your family’s carbon footprint. That doesn’t mean that everyone has to give up pancakes just because mom has a gluten allergy, but it does mean that you’re more likely to make heather choices not just for yourself, but for those around you, too.
