Weekday Vegetarian Diet: 0.7 Tons
Not ready to cut meat out completely? A "weekday vegetarian" diet -- where you go veg from Monday to Friday each week -- can be a nice starting point, a good middle ground in usually very binary subject matter, for those who aren't prepared to cut out meat completely. Not surprisingly, its impact is less than the full-on version, but it allows for more flexibility when dining out, enjoying a dinner party, or other fun weekend dining options.
And, for those scoring at home, 0.7 tons, or about 1400 pounds, is about the same amount of carbon dioxide emissions generated by one round-trip flight from Boston to Wichita, Kansas. Yep, one year of vegetarian eating equals one flight. Makes you think twice about flying, eh?
