Paul McCartney had an idea of meat-free Mondays which he actually introduced to the EU.

The musician/vegetarian from the Beatles is taking his campaign global and is dead serious about people avoiding meat on Monday.

He addressed the European Parliament:

“I grew up as a kid not eating meat on Fridays,” McCartney told reporters. “It was part of the rules of the school I went to.

At a time of concerns over global warming, McCartney added, there are “even more crucial reason” to skip meat.

The former Beatle and well-known vegetarian said the production of food — from farm to fork — accounts for 20 to 30 percent of global green house gas emissions. Livestock production is responsible for around half of these emissions.

Still, he admitted that his flight from London to Brussels — and on to Berlin for a concert later Thursday — had contributed to global warming.

“They haven’t invented microphones that work on candle power,” he said. “I do everything I can. If I go for a car, I go for hybrid. I recycle.”

I guess he sees how hard it is to not affect the environment around you. Plus getting people to not eat beef would be a small miracle as well.
