According to the Times, Lord Stern has gone Vegetarian in an attempt to save the planet. The simple reason is that methane (which cattle and pigs produce in vast quantities) is 23 times more potent as a greenhouse gas than CO2. We therefore need to cut back drastically on the quantity of cattle. But hold on a minute. We also get milkfrom cows as well. Should we be switching to Soya milk and synthetic cheese? Lord Stern

“predicted that people’s attitudes would evolve until meat eating became unacceptable. “I think it’s important that people think about what they are doing and that includes what they are eating,” he said. “I am 61 now and attitudes towards drinking and driving have changed radically since I was a student. People change their notion of what is responsible. They will increasingly ask about the carbon content of their food.”

So when the eco-fanatics start attacking the meat counter of Tescos and sabotaging the school milk deliveries, we will know who to charge with incitement to commit acts of criminal damage and terrorism. Make a change from them dumping manure and sabotaging tyres ot 4x4s.
