Back in the 60s there was a rumour that Paul McCartney was dead and had been replaced by a look-alike. Apparently there were clues to this hidden in Beatles songs that became audible when played backwards but it quickly become clear after the Beatles split that it was only his song writing skills that was pushing up the daises.
To anyone under 35 he is probably most famous for dying his hair, singing that terrible frog chorus song and divorcing that one legged woman but he is also a well known vegetarian.
He is now one of the names putting their weight behind Meat Free Monday, which aims to persuade people to go veggie once a week to reduce greenhouse gas emissions from the world's livestock.
According to the UN Food and Agriculture Organisation, meat is responsible for 18% of greenhouse gas emissions which is more than all the cars, trucks, planes and ships in the world combined.
There does seem to be a movement towards vegetarianism after the Belgian city of Ghent announced its commitment to the cause by going vegetarian for one day a week rather than fiddle about with changing some light bulbs.
I'm a vegetarian so of course i agree with the message but people are not going to give up meat, even for a day, just because some scouse bass player asks them to even if it is for saving the planet.
We need sensible, grown up debate to bring across the masses so remember that you are what you eat. Enjoy that big, fat pig won't you.
