     "People should have one meat-free day a week if they want to make a personal and effective sacrifice that

would help deal with climate change," the world's leading authority on global warming has told The Observer.

     Dr Rajendra Pachauri, chair of the United Nations Intergovernmental Panel on Climate Change, said that

people should then go on to reduce their meat consumption even further.

     Pachauri, who was re-elected the panel's chairman for a second six-year term last week, said diet change

was important because of the huge greenhouse gas emissions (排放) and other environmental problems

associated with raising cattle and other animals. "It was relatively easy to change eating habits compared to

changing means of transport," he said.

     The UN's Food and Agriculture Organisation has estimated that meat production ac counts for nearly a

fifth of global greenhouse gas emissions. These are produced during the production. For example, ruminants

(反刍动物), particularly cows, emit a gas called methane, which is 23 times more effective as a global

warming agent than give off CO₂.

     Pachauri can expect some opposite responses from the food industry to his advice, though last night he

was given unexpected support by Masterchef presenter and restaurateur John Torode. "I have a little bit and

enjoy it," said Torode. "Too much for any person is bad. But there's a bigger issue here: where the meat

comes from. If we all bought British and stopped buying imported food, we'd save a huge amount of carbon

emissions."

     Professor Robert Watson, the chief scientific adviser for the Department for Environment Food and Rural

Affairs, said government could help educate people about the benefits of eating less meat, but it should not

regulate. "Eating less meat would help, there's no question about that," Watson said.

     However, Chris Lamb, head of marketing for pig industry group BPEX, said the meat industry had been

unfairly targeted and was working hard to find out which activities had the biggest environmental impact and

reduce them. "Some ideas were contradictory," he said. "For example, one solution to emissions from cattle

and other animals was to keep them indoors, but this would damage animal welfare. Climate change is a very

young science and our view is ther are a lot of simple solutions being proposed."
