less meat means less heat!

Less meat means less heat. It’s a slogan that leading scientists hope will catch on worldwide, part of a call for people to reduce consumption of meat and dairy products to slow the pace of climate change.

Writing in the medical journal The Lancet, a team of international health experts led by Tony McMichael warns that the world’s growing appetite for meat is increasing greenhouse gas emissions, as vast areas of rainforest are bulldozed for grazing land and as more sheep and cattle burp.

Professor McMichael of the National Centre for Epidemiology and Population Health at the Australian National University, Canberra, and his colleagues argue that “for the world’s higher-income populations, greenhouse-gas emissions from meat eating warrants the same scrutiny as do those from driving and flying”.

According to a study published in July by Japanese scientists, a kilogram of beef generates the equivalent of 36.4 kilograms of carbon dioxide, more than the equivalent of driving for three hours while leaving all the lights on back home.
