Almost 1/3 of all land on Earth is used for livestock production and agriculture is the single biggest emitter of greenhouse gases. Introducing Meat Free Monday to your school or workplace not only dramatically reduces your institution's greenhouse gas emissions but also helps raise awareness about the environmental issues associated with the agriculture industry. It also shows people that there are great veggie dishes on offer and help persuade them that they can easily reduce their meat consumption and don't have to become fully vegetarian to make a difference.
