LOS ANGELES – Look out, Al Gore ... People for the Ethical Treatment of Animals says you are refusing to face one very "inconvenient truth."
On Monday, the animal rights organization launched the campaign offsetalgore.com (conveniently timed for Earth Day) in an attempt to counter the effects that they say the former vice president's meat-laden diet has on Mother Nature.
While reps for Gore had no comment, Pop Tarts confirmed with people who have worked with the ex-veep that he loves his steak and sausage, plus he was notorious for chowing down on the almost all-meat Atkins diet during his run for president.
A recent report published by the United Nations determined that raising animals for food generates about 40 percent more greenhouse gas emissions than all the cars, trucks, ships and planes in the world combined.
"Livestock are one of the most significant contributors to today’s most serious environmental problems," said Henning Steinfeld, chief of the Food and Agriculture Organization's Livestock Information and Policy branch and senior author of the report. "Urgent action is required to remedy the situation.”
So while Gore is known worldwide for his environmental activism and efforts to build awareness about global warming, is our steak-lovin' "Earth Day" man a hypocrite? PETA certainly seems to think so.
The campaign encourages people to go vegetarian for 30 days and claims that that is enough time to prevent the release of more than 270 pounds of carbon dioxide into the Earth's atmosphere. Studies suggest that this will prevent more pollution than if a person left his or her car at home every weekday for 30 days.
Speaking of which, researchers at the University of Chicago also found that converting to a vegan diet is about 50 percent more effective in countering global warming than switching from a standard American car to Tinseltown's fave Toyota: the Prius.
"Americans now eat 1 million birds an hour, and yet Mr. Gore has not mentioned the fact that poultry production is a huge problem — one reason we have him holding a drumstick in our ad asking him if he’s 'too chicken to go vegetarian,'" said Ingrid E. Newkirk, the president of PETA.
"Given the fact that vegetarians are on average much slimmer than meat-eaters, Mr. Gore doesn’t even remotely look as if he is fond of vegetables, grains and fruit," she said. Ouch!
Scoop: Michael Johns' Wife 'Cried All Night'; Shar Jackson Bags on K-Fed's 'Career'
All the "pop tarts" certainly came out to play last Thursday night at Us Weekly magazine's Hot Hollywood bash held at Eva Longoria's restaurant Beso.
But even though he was bitterly booted off "American Idol" two weeks ago, Michael Johns held his head high, although that's not to say he isn't still hurting.
"It was pretty heartbreaking, especially how it was done — it was brutal," said Johns in reference to his harsh elimination. "I kept it together OK; it was the wife who cried all night. I was the one telling her that it was all going to be all right."
Speaking of singing, emerging songstress Shar Jackson rocked on well into the wee hours and pretty much verified what we always knew: Her former flame Kevin Federline can't sing.
"Let's just say out of the two of us I'm the only one who holds the golden mic," she said. "He tried to do the music thing. Did it work? You be the judge. I think it's time for him to let it go and now it's my turn." Yikes.
Meanwhile, Lauren Conrad may be the star of a hit reality series and Us Weekly's "Designer of the Year," but we aren't convinced that she really understands the upcoming election.
When we asked which candidate she was leaning toward, "The Hills" hottie responded: "I'm supporting anyone who wants to vote." (What the?)
We also noticed "Step Up to the Streets" starlet Jenna Dewan (who has been dating Channing Tatum for a few years now) dancing and drinking upstairs in the VIP lounge with her ex-boyfriend Shane West.
"They were together all night," another eyewitness told Tarts. "They are obviously still very close, but Channing was nowhere to be found and Jenna seemed more than comfortable with Shane."
Gwen Stefani Rejects Lifeguard Help on the Beach
Pop Tarts spotted a super-pregnant Gwen Stefani, hubby Gavin Rossdale and their nearly 2-year-old stroller-bound son, Kingston, walking along the boardwalk in sunny Santa Monica last Saturday.
Stefani was happily chatting on her cell, even giving Pop Tarts a friendly wave. But this is certainly one rock star that doesn't need more than one man to look after her.
According to a lifeguard patrolling the sands, they offered to "protect" the platinum-blonde babe from any lingering paps, but she politely declined.
"We were willing to give her a private space and get rid of any paparazzi, but she said she didn't need it," the guard said.
Kate Hudson's 'Busy' Birthday Weekend With Owen
Are they or aren't they?
The question still remains unanswered as to whether former flames Kate Hudson and Owen Wilson have reunited romantically. Both camps have been busy denying rumors that they're back on, but they were busted celebrating Kate's 29th birthday in Miami over the weekend.
The "You, Me & Dupree" duo were pap-snapped snoozing in the sunshine when Hudson decided to make her moves and jump all over the resting Owen.
Lindsay LohAAN: A Lost Cause?
Oh dear — all those dollars spent on three romps into rehab seem to have been "wasted" just as badly as Lindsay Lohan reportedly was on Saturday night.
Li-Lo ventured into the Big Apple with her gal pal Samantha Ronson, and the best buds made their way into Times Square's Hawaiian Tropic Zone around midnight in matching leather jackets.
But while DJ Sam spun records, our Linds passed the time by busting moves to Britney Spears' songs and downing Grey Goose vodka, according to People magazine.
The two gals were busted boogying around 4:15 a.m., but we're told by a pap snapper that Lindsay looked particularly under the weather. Sigh.
