Hitting the drive through a few times a week does have a huge impact. In fact, Collin wrote that America's love of hamburgers contributes approximately 941 to 1023 pounds of greenhouse gas emissions per person, per year - the rough equivalent of the annual carbon output from 7,500-15,000 SUVs, assuming 300 million U.S. citizens consumed the 3 burgers/week average.
On the other end of the spectrum, where the average American household to avoid red meat and dairy and, instead, consume a vegetarian diet or a diet including some chicken, fish, and eggs, the decline in greenhouse gas emissions would be equal to driving 8,000 fewer miles. That's like driving from Miami to Seattle and back.
What's more, low emission foods are often equally priced or less expensive. For example, seasonal fruits and vegetables, which are essential to reducing your carbon footprint, are generally more widely available and less expensive. In addition, meat is costly. Making meatless meals for the family is often times the more frugal way to go. While not all low emission foods are less expensive, these seven foods definitely are.
