Cut global warming by becoming vegetarian

July 7, 2005

Global warming could be controlled if we all became vegetarians and stopped eating meat. That's the view of British physicist Alan Calverd, who thinks that giving up pork chops, lamb cutlets and chicken burgers would do more for the environment than burning less oil and gas.

Writing in this month's Physics World, Calvert calculates that the animals we eat emit 21% of all the carbon dioxide that can be attributed to human activity. We could therefore slash man-made emissions of carbon dioxide simply by abolishing all livestock.

Moreover, there would be no adverse effects to health and it would be an experiment that we could abandon at any stage. "Worldwide reduction of meat production in the pursuit of the targets set in the Kyoto treaty seems to carry fewer political unknowns than cutting our consumption of fossil fuels," he says.

Physics World is the international monthly magazine published by the Institute of Physics.
