Meat Free Monday is a global campaign based on not eating meats on Mondays. It is Launched by Paul, Mary and Stella McCartney in 2009.  Eating meat-free one day a week could reduce the climate impacts of the foods. It may seem like a small step, but when it is considered lots of people do not eat on Mondays, it could be a huge movement. It is a project that started to achieve these goals. Now, the campaign held on in the UK, US, Canada, Australia, Belgium, Brazil, Taiwan, Japan, Germany, and Russia. São Paulo which is a city in Brazil (with 10 million people), has the Meatless Mondays. No matter Brazil is one of the countries that exports meat mostly in the world.
