Cooking meat consumes more oil and gas and can be a cause of Global warming.
The British physicist Alan Calverd, writing in this month's 'Physics World' said:
"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 feels that giving up pork chops, lamb cutlets and chicken burgers would do more for the environment.
He adds that the animals we eat emit 21 percent of all the carbon dioxide that can be attributed to human activity. By abolishing all livestock we could slash man-made emissions of carbon dioxide.
