In the '80s, people sang "We Are the World," but for Earth Day 2013, PETA gave that idea a very literal spin: Instead of wearing their hearts on their sleeves, these good folks took off their sleeves (and everything else) in favor of blue and green bodypaint for a demonstration in Vancouver. They reminded everyone who saw them that we can help the planet simply by choosing healthy and humane vegan foods.

So remember: If you want to save the world and its inhabitants (or just look your best without clothes), going vegan is the best way to start!

Last Friday was especially good for animals. In honor of the Christian holiday Good Friday, PETA pigs were out in front of the HoneyBaked Ham store in Oakland, California, and lots of other stores, too, joined by friends holding signs like the one below and "It's a Good Friday to Go Vegan."

We also handed out copies of our "Glass Walls" video and vegan starter kits to curious customers, showing them what really happens to pigs before they become a honey-baked ham. (Spoiler: It's anything but merciful.) It was plenty of food for thought for Easter patrons.

Because of the throngs of people who had gathered outside to protest, it was hard to spot those who were trickling into Brooklyn's Barclays Center on Ringling Bros. circus's opening night. More than 200 animal advocates came together to make sure that Ringling's reception was chillier than a New York winter.

While half the group circled the block, hoisting signs and chanting, the other half flanked the crosswalks and handed leaflets and educational coloring books to parents and children.

If any of the attendees weren't aware of how Ringling abuses animals, they certainly were after they saw the behind-the-scenes photos of trainers slamming baby elephants to the ground, gouging them with steel-tipped bullhooks, and shocking them with electric prods. And if that didn't do the trick, the screening of PETA's video exposé narrated by Alec Baldwin, which showed trainers beating and tormenting elephants, moments before a performance likely did.

Many of the advocates plan to return to the Barclays Center every night that the circus is in town to make sure that everyone in the Big Apple gets the message about cruelty under the big top.

Last week marked the end of legal public nudity in San Francisco—and you wouldn't expect PETA to sit it out, would you? Several all-star volunteers gathered full-monty style at City Hall to protest the theft of animals' skins by declaring that they are comfortable in their own skin. 

Unlike humans, who can (or at least used to legally be able to) choose how much skin to expose in public, animals raised and killed for their skins often have their flesh unwillingly ripped off their bodies while they're still alive. Please don't ever buy leather, fur, or other items made from animals' skins and fur—choose garments and accessories made from pleather, faux fur, and other cruelty-free materials instead!

Every year, people who exploit chickens and reduce them to bits in a bucket gather at the International Poultry Expo to congratulate each other on making money at it. So this year, PETA sent a flock of "birds" to suggest that attendees give a cluck about chickens:

Banging on pots and pans and shouting, "We are not nuggets!" the chickens got everyone's attention. A surprisingly large number of attendees accepted the demonstrators' leaflets and listened to explanations of how chickens suffer on factory farms and in slaughterhouses, including being mutilated and drugged, having their throats slit while still alive, and often being scalded to death. 

It was an educational expo indeed.

Would PETA miss the chance to educate nearly 1 million people about the benefits of vegan eating? Kale no!

Attendees of President Barack Obama's inauguration were so smitten by Chris P. Carrot, Celery Stalk, and Mother Earth that they actually lined up to have their pictures taken with the patriotic trio and snatched up vegetarian/vegan starter kits and copies of "Glass Walls"—a video narrated by Paul McCartney—while they were at it.

The vociferous vegetables even managed to win over a woman who was willing to consider eating fewer animals than she was wearing:

In his inaugural speech, President Obama promised to "respond to the threat of climate change." We can't think of an easier—or tastier—way to do that than by going vegan.

Are you still trying to cool off from the scorcher that was 2012? Scientists report that it was the hottest year on record for the U.S.—but instead of blaming Mother Nature, we can point the finger at ourselves. "It is abundantly clear that we are seeing [human-caused] climate change in action," according to Kevin Trenberth, a senior scientist at the National Center for Atmospheric Research.

So PETA sent the greenest gals we know on a jaunt across Canada to show people how easy it is to go green—no bodypaint required. Since carbon dioxide, methane, and nitrous oxide together are the biggest contributors to climate change and raising animals for food is one of the largest sources of carbon dioxide emissions and the single largest source of both methane and nitrous oxide emissions, going vegan has been called the "single most effective thing you can do" to combat climate change. 

People eagerly posed for pictures with the lime ladies, and they took home PETA's "Meat's Not Green" leaflets and copies of legendary animal and environmental advocate Paul McCartney's meat industry exposé, "Glass Walls." 

By simply opting for faux meats and dairy products over animal-based ones, we can make 2013 a lucky year for animals and help reduce climate change. And that's pretty cool.

When you mess with bears, sometimes you get hurt. Of course, PETA's "bear" didn't actually harm a hair on the heads of the animal abusers at Chief Saunooke Bear Park (CSBP) during a protest last weekend, but he and about two dozen of his friends did bite back against the cruelty at the vile roadside zoo.

PETA's protest comes less than a week after the release of the findings of our undercover investigation of CSBP that unearthed evidence of systemic neglect and abuse of bears (including shooting and eating one of them), threats of violence, illegal drug use, sexual harassment, and racism by the park's staff. We are calling for the closure of the hellish bear pits and the seizure of the surviving animals.

What You Can Do

If you didn't make it to the demonstration, don't worry—you can still help the bears suffering at CSBP by asking the U.S. Department of Agriculture to confiscate all animals from the shabby roadside zoo immediately and place them in a suitable sanctuary.

PETA made sure that grocery shoppers didn't wind up in a pickle when the eco-friendly ban on plastic bags went into effect in Oakland, California. A convivial carrot and personable pickle offered shoppers at one grocery store free tote bags that were greener than a cucumber salad.

That's because not only did the bags help shoppers stop contributing to plastic-bag pollution, they also illustrated how much the meat industry pollutes the air, water, and soil. Inside their new bags, shoppers found a DVD of Paul McCartney's meat industry exposé "Glass Walls" and a vegetarian/vegan starter kit.

Many shoppers told the pair of produce that they were trying to be greener or were thinking about going vegan. And the green goodies were such a hit that employees came out of the store to ask if they could take some inside because customers were asking for them.

If you didn't get one of the totes, don't go out of your gourd. Pick up a vegetarian/vegan starter kit, a "Glass Walls" DVD, and a PETA bunny tote to help you be healthier and more Earth-friendly, and make your friends go green with envy. 

When we planned a demonstration involving people lying on what appeared to be bloody meat trays outside a slaughterhouse, we knew that it would be a poignant display. But even we had no idea just how intense it would turn out to be.

The smell of freshly butchered flesh that permeated the air around the John Morrell & Co. slaughterhouse was nauseating on that sweltering day in Sioux Falls, South Dakota. But that wasn't the worst part. The slaughterhouse was directly across the street from a stockyard, and we could hear the pigs screaming. Their unceasing cries shook us to the core.

The townspeople who drove by us certainly got the message—they were faced with the gruesome image that accompanied the smells and screams that they always tried to ignore as they passed. One slaughterhouse worker even came out to ask, "Are you all vegetarian?" When we answered that we were, he said, "I don't blame you."

Today, wherever you are, please be the message that people can't ignore.

The animals are not silent. We must not be, either.
