For each hamburger that originated from animals raised on rainforest land, approximately 55 square feet of forest have been destroyed.
Consider the amount of pollution created to get your food from the farm to your table. Whenever possible, buy from local farmers or farmers' markets, supporting your local economy and reducing the amount of greenhouse gas created when products are flown or trucked in.
