Go Veggie for a Day by Madi

As climate change continues to be a major issue in our society, the evidence is growing that being vegetarian can help save both our planet, as well as trillions of dollars. By replacing meat with vegetarian sources of protein, such as nuts, beans, and lentils, we can reduce carbon and other greenhouse gas emissions. Studies show that eating a vegetarian diet means 2.5 times fewer carbon emissions than a meat diet. It can be very difficult to transition into a committed vegetarian diet. However, if everyone ate vegetarian for just one day a week, we would see many improvements in our climate. Kathy Freston previously published data about the impact of going vegetarian for a day. The data indicated that "as a country eating vegetarian for one day, we would save 100 billion gallons of water, 1.5 billion pounds of crops that would otherwise be fed to livestock, 70 million gallons of gas, 3 million acres of land, 33 tons of antibiotics; 3 million tons of soil erosion and $70 million in resulting economic damages." Just one day of a vegan diet can have a significant impact on the earth. With all of these positive impacts, a vegetarian diet for one day per week doesn't seem too bad.
