It’s well known that meat production has a large carbon footprint. A diet that includes meat requires more land than a plant based diet so even decreasing the amount of meat one eats can be a good thing. Some fans of vegetarian diets have created the Vegetarian Calculator that lets people know how good their diet is.
Use this form to calculate the impact you have made by being a vegetarian. Vegetarians use less resources like water, food, oil, contribute less CO2 to the atmosphere, and animals are not killed for their consumption.
Raising livestock contribute more to global warming than automobiles, and is the second leading cause of global warming behind industrial pollution.
