It’s no coincidence that many eco-fanatics are vegetarians. Still, this idea has some merit:

Sir Paul McCartney has followed in the footsteps of the world’s leading climate scientist and a small Belgian town by calling on people to go meat-free one day a week and cut carbon emissions.

Backed by celebrities ranging from Chris Martin to Sheryl Crow, McCartney today launched his Meat Free Monday campaign asking households to cut out meat on Mondays and slow global warming.

“I think many of us feel helpless in the face of environmental challenges, and it can be hard to know how to sort through the advice about what we can do to make a meaningful contribution to a cleaner, more sustainable, healthier world,” said McCartney. “Having one designated meat free day a week is actually a meaningful change that everyone can make, that goes to the heart of several important political, environmental and ethical issues all at once.”

Reducing meat consumption didn’t just slow climate change, he said, but would help to fight global hunger and improve the welfare of animals.

With climate change as its excuse, perhaps the Catholic Church can go back to encouraging its adherents to eat fish on Fridays.
