It’s not often activists find a platform they can all rally around. Even people on the same side of an issue will argue the nuances of their positioning as though their lives depended on it.

But Al Gore, of all people, has given animal rights activists a platform – global warming. And they’re aiming the gun at his carnivorous ways.

A new PETA ad calls out meat as the top cause of global warming. And other agencies are jumping on the bandwagon.

Now, liberal though I am, I typically dismiss PETA’s allegations out-of-hand. They’re the best example of sensationalist activists I can think of (on my side of the fence). But they actually have the U.N. to back them up this time.

The research I’ve done indicated PETA is spinning a complex issue. At the very least, meat doesn’t cause global warming, our production practices do.

What do you think? Do I have to give up meat to save the world?  — Brigitte Lyons
