Singer Paul McCartney yesterday launched a Meat-Free Monday campaign, which encourages consumers to help slow climate change by avoiding meat one day a week.
Celebrity supporters include Chris Martin, Alec Baldwin, Woody Harrelson, Sheryl Crow, Kevin Spacey, Kelly Osbourne, Gillian Anderson and Ricky Gervais.
Studies clearly show our food choices affect the environment. The UK's Food Climate Research Network says food production is responsible for 20%–30% of global greenhouse gas emissions. Farm animals, which release gases like methane and nitrous oxide, account for 50% of food-related emissions.
In fact, livestock production is globally responsible for more climate-changing emissions (18%) than transportation (13%), according to the United Nations Food and Agriculture Organization. And Compassion in World Farming says UK families that slash meat consumption by 50% would release fewer emissions than if they drove their cars 50% less.
Nobel Peace Prize winner Rajendra Pachauri, PhD, chair of the Intergovernmental Panel on Climate Change, said last year:
“IPCC found that changes in lifestyle and behavior patterns can contribute to climate change mitigation across all sectors. One area where individuals can make a difference in this regard is by altering their diets through consuming less meat, say by giving up meat at least one day a week. Reducing meat consumption in this manner will make individuals healthier, as well as the planet.”
“I think many of us feel helpless in the face of environmental challenges, and it can be hard to know how to sort through the advice about what we can do to make a meaningful contribution to a cleaner, more sustainable, healthier world. Having one designated meat-free day a week is actually a meaningful change that everyone can make that goes to the heart of several important political, environmental and ethical issues all at once. For instance, it not only addresses pollution, but better health, the ethical treatment of animals, global hunger and community and political activism.”
