Watch your diet. What you eat affects more than your waistline, it has an impact on our planet. The traditional American diet is high in animal products, and processed foods which by nature uses more energy than that used to produce staple foods such as potatoes, rice, fruits and vegetables. By just reducing your processed food intake and limiting your consumption of meat, you could have a massive impact on fuel consumption as well as improving your overall health. Just adhering to a vegetarian diet one day a week would make a significant impact on your carbon footprint. Try it!
