Rescuing lost dogs with her mom at a young age really made an impression on Alicia Silverstone. In her late teens, the actress started exploring cruelty-free products; by age 21 she was a full-on vegan; and at 23 she was subscribing to an eco-friendly lifestyle.

“It took so much effort to find out what products aren’t tested on animals — that was an ordeal,” Silverstone told reporters recently during a press event for EcoTools in New York. “But then when I became into eco, it took out all of that: if you’re using all-natural products that have no toxic chemicals, it narrows the playing field.”

These days, the actress is a strong advocate for all things green — she even makes the very anti-Hollywood choice of buying used clothes. “My second stop would be organic cotton,” she said. Scouring Craigslist for household items — “Then you get it really locally, and it already exists,” she explained — she stressed that she doesn’t sacrifice taste and style when shopping secondhand, either. “I realize if you’re not happy with what you have, you want to change it out more,” she shared.

Though she admitted that sometimes finding specific products can take time — “Shoes are a little trickier, but they exist,” she said — making these informed choices is necessary in her mind. “I’m trying to save the planet,” she said. “I’m trying to save our lives.”

While Silverstone doesn’t have the time to make her own eco-friendly beauty and home products just yet — “I have so little time to even take a shower,” the new mom and blogger joked — she said it’s not an impossibility. “Maybe there will be a time where I’m making brownies for my kids and making soap,” she mused, “and that’s all I’m doing.” Tell us: Do you keep your home green?

SEE STARS RECYCLE THEIR LOOKS IN ‘I REALLY LOVE MY …’

After visiting Haiti following the earthquake of 2010, Maria Bello was inspired to help. So the actress rounded up some associates and founded We Advance, an organization designed to help the poorest victims get back on their feet, receive adequate healthcare and have access to an education.

To raise funds for her non-profit, Bello is partnering with LovingEco.com this week; she curated products for a sale on the environmentally friendly site, and in turn, they’re donating three percent of proceeds to We Advance.

“People often ask me how they can help — they don’t know where to start,” Bello tells PEOPLE. “LovingEco offers people the chance to give back, while also providing fashionable products. It’s about style for change.”

Items in Bello’s sale include the We Advance necklace, designed by Caroline Sada, Shelley Clay and the female artisans of The Apparent Project, another organization that helps Haiti’s neediest residents. “Each bead is handmade from recycled cereal boxes, and the medallion pendant is made from recycled oil drums,” Bello explains.

The Prime Suspect star says she tries to shop organically when she can. “I, for one, am more apt to buy a product that I know will benefit the artisans who made them, and support eco and social consciousness,” she shares. “Also, I have found that people love getting a gift that gives back!” Shop Bello’s sale on LovingEco.com through Sunday.

CAN YOU GUESS THE STAR BARGAIN?

When Entourage star Adrian Grenier launched SHFT.com last year, his goal was to bring the best in sustainable product to his readers and fans. Now, he’s moving forward with that mission, curating a two-day sale on GILT that includes some of his favorite eco-friendly apparel and accessories for men. “GILT is good at what they do, and we’re good at what we do, so it made sense to do this collaboration,” Grenier tells PEOPLE. “Our goal at SHFT.com is to reach a critical mass so that all products we love and are sustainably minded will ultimately become less and less expensive. So it’s right up our alley to be able to put affordability and sustainability into the same sentence.” The GILT sale, which runs from noon ET today until noon ET on Friday, includes Simple shoes, a bike from Nirve, Daniel Moyer Designer longboards, Core Bamboo bowls, tables from Alex Artless and casual menswear from Nau. A portion of sales will benefit the Webby award-winning SHFT.com. Grenier says that while he makes a point of purchasing sustainable products, it’s not quite possible to shop in an exclusively eco-friendly manner just yet. “You do what you can, and that’s the reality of where we are,” he shares. “To me, it’s not about being absolute in your life, it’s about making a sincere, dedicated effort to make this meaningful shift in your life. I think as our demand goes that way, designers and producers will, too.” And he’s using his website to help the cause. “My dream is that one day, SHFT.com will be the only site you go to for products, because it’ll have everything you need, and everything will have a sustainable element. So that’s my goal.” –Kate Hogan

SHOP DISCOUNTED CELEB STYLE IN ‘STAR LOOKS FOR LESS!’

Shortly after announcing her second eco-friendly fashion collaboration, Emma Watson has expanded her stylish résumé yet again, this time for a “green” capsule collection with Italian designer Alberta Ferretti. According to WWD, the line, called Pure Threads, consists of five pieces: two dresses, a shirt, a long skirt and a pair of denim shorts, all enriched with lace embroideries and made with organic fabrics such as cotton poplin, cotton muslin and hemp. “Emma had a Jane-Birkin-in-the-Seventies image in mind,” Ferretti told WWD about the starlet’s inspiration. A portion of proceeds from the collection will be donated to People Tree, a nonprofit organization Watson supports. “I’m pleased that a luxury brand such as Alberta Ferretti has decided to create ecological clothes,” said Watson. “I believe this is a big step forward for all of the international fashion industry, but also an important step for an increased sensitivity to the problem of ecology.” Pure Threads will be available exclusively on albertaferretti.com beginning March 21. –Kim Peiffer

Emma Watson is showing the world that fashion can be eco-friendly through her latest Fairtrade Fortnight collection with People Tree. In this video from the new campaign, Watson shows off some pieces from the new spring/summer collection, which promotes the issue of sustainability in the fashion industry. “The design process continued with me trying on each and every piece to get the fits just as I wanted them and then I visited Bangladesh to see the clothing actually being made and meet the people making it,” said Watson. “It was an incredible and life-changing experience –I really wish everyone had the chance to see the difference Fair Trade makes with their own eyes.” And she says there’s many things about fair trade clothing that may surprise us. “Fair Trade fashion is often completely handmade – and made of 100% natural and organic cotton – and it’s a small miracle that we as consumers can participate in a process that is keeping skills and communities alive and helping them to prosper.” Look for dresses made from silk gingham checks, florals, polka-dot handweaves and jersey wrap arounds, as well as more relaxed styles in the form of  playsuits, harems and kimono jersey shirts.

While Colin Firth struts up every red carpet event in the run-up to the Oscars, where he is nominated for Best Actor in the acclaimed film The King’s Speech, his wife Livia Firth is embarking on a Green Carpet Challenge. Taking advantage of the fact that she’ll often be photographed by her husband’s side, Firth decided to bring eco-couture to the red carpet by wearing designers who care about environmental and social justice causes. Firth said she wanted to capitalize on the spotlight by using “this as an opportunity to promote sustainable style and ethical fashion, because these are the things I care about,” she tells the British Observer Magazine this past Sunday. It’s a cause close to Livia’s heart since she owns an eco-retail store in West London. Some of her dresses have even been made from recyclable materials. Last year, Firth wore a black dress to the Oscars designed by Orsola de Castro, which was made of materials retrieved from the dumpsters of fashion houses. For this year’s Golden Globe awards, her dress was dyed by homegrown indigo plants from designer Jeff Garner’s community garden in Tennessee. “I really hope we can convince some big names to sign up and start wearing ethical designers. It can be a little lonely out there. For the moment, they’ll have to put up with me,” said Firth. – Helen I. Hwang

When Crystal Bowersox announced her engagement to fellow musician and longtime friend Brian Walker last month, she promised to be anything but the typical bridezilla — and from her unique earth-friendly dress to her diamond-free wedding ring, the season 9 American Idol runner-up seems to have stayed true to her word. The bride wore an organic, hemp and cotton wedding gown from Vermont designer Tara Lynn to exchange her vows on Sunday at the Chicago café where she first met Walker six years ago, saying ‘I do’ with a 1.1-carat princess cut ruby ring designed by Walker and crafted by Chicago’s Traci Coughlin and Steve Quick Jewelers. “There are no diamonds to be found as we don’t believe in the violence and injustice that occurs within the diamond trade industry,” Bowersox tells PEOPLE. “Both rings feature the masonry symbol, an infinity 8, and the Sanskrit symbol for the sound ‘om’ and a personal design that for us represents three: Brian, Crystal, and Tony.” As for her one of a kind wedding dress? “The gown is a simple princess line with an open back; a machine-knit hemp twine strap crisscrosses in back,” says designer, Tara Lynn. And new bride Bowersox couldn’t have been more pleased with the results. “I gave Tara Lynn the base ideas of what I wanted, and in three weeks, she created a beautiful gown made of hemp and cotton, with a handmade macramé and bead sunflower design on the front,” Crystal tells PEOPLE. “The train of the dress is a handmade design of hemp twine, sea shells, and beads, some of which came from pieces of sentimental jewelry.” Read more details on Crystal’s intimate Chicago wedding in the current issue of PEOPLE, on newsstands Friday. –Gillian Koenig; reporting by Marisa Laudadio

When Vanessa Hudgens and Hayden Panettiere hit the beach yesterday in L.A., it wasn’t just to soak up the rays. The two beautiful actresses (and Neutrogena brand ambassadors ) joined forces to announce the new Neutrogena Wave for Change campaign, a charitable initiative that lets teens help the company decide how to distribute up to $200,000 from sales of the Wave Sonic Power-Cleaner and Oil-Free Acne Wash Pink Grapefruit product sold for disaster relief, education and environmental causes through GlobalGiving. Through August 23, visitors to the Neutrogena Facebook page can take a quiz to see which cause they’d like to support, which will help determine where funding eventually goes. “Often people want to participate, but they don’t know how so the fact Neutrogena is opening the door and kids are getting to be a part of something and help the world is an amazing thing to be a part of,” says Panettiere. Hudgens seconds the feeling, telling PEOPLE that “It’s so cool that Neutrogena is letting the fans go to Neutrogena’s Facebook page to take a quiz to determine how the money raised for charity is being distributed. By taking a few minutes to join in, everyone can make a big difference in the world.” Go to Facebook.com/Neutrogena to take the quiz today!

Some celebs, like Bell, who walked away with two bags of goodies, were already Loomstate fans. “I love their fun animal prints and I love casual clothes,” the actress told PEOPLE.com. “Plus, their cotton tends to be very soft, so I’m looking forward to getting a whole bunch of jammies.” Others, like Banks and Pressly, were new to the eco-chic brand, created by designers Scott MacKinlay Hahn and Rogan Gregory. “This is the first time I’m seeing it — and I’m in love already,” Banks enthused.

No matter what’s happening in her life, Madonna is still in love with British brand Bodas’s organic supima cotton T-shirts. The singer wears them “to work out, to run errands, to go out — she loves them for everyday,” a source tells PEOPLE. (She also likes them for primetime — she wore a black short-sleeve T in her 4 Minutes video with Justin Timberlake.) A Bodas spokeswoman tells PEOPLE that the singer most recently purchased a handful this summer. “She wears them out, and then her assistant comes in and buys five more,” she says. And unlike, say, Madonna’s one-of-a-kind designer tour outfits, you can actually purchase these looks. They’re $90 for a tank top or short sleeve, and $98 for long-sleeve styles, available at www.bodas.co.uk or at Barneys New York. – Courtney Rubin

We’ve been chalking up Kate Moss‘s radiant appearance to boyfriend Jamie Hince, but it turns out it’s actually all thanks to the ultimate rock chick turned eco-beauty junkie Jo Wood. The wife of Rolling Stone rocker Ronnie Wood and founder of the Jo Wood Organics beauty line tells PEOPLE at her Everyday Range product launch how she convinced the supermodel to go organic. “I opened her fridge to see what was organic and there was nothing. I started telling her how important it is for her little girl.” And the mom of five-year-old Lila Grace is now almost 100% converted, including using Jo’s beauty line. “Kate loves the stuff, she loves all the oils,” adds Wood. As for the model’s bright complexion, Wood chalks it up to her new organic food regimen. “It’s amazing she can get away with it. She still likes to have a good party, but her skin looks good still. I told her! You have to look after your skin but it’s what you put in you as well.” So where should an organic beginner start? “Read the labels,” Jo says. “Once you start reading labels then you only want to have things that you understand in your products.” Consider us converted.

Former Primp designer Alexx Jae launched a line of organic t-shirts for the Environmental Media Association on February 13 at one of LA’s premiere fashionista havens, Milk, whose clients include Zooey Deschanel, Rachel Bilson, Mandy Moore, and the Simpson sisters. “People think the environment is so not cute or hippie-ish, and I wanted to show that it could be really hip and cute,” says the L.A.-reared designer, who no doubt was inspired by her mom, the head of EMA. The super-soft tees and cardigans feature pro-environment messages written in light ink, like “Where’s your hybrid?” and “Compact fluorescents are sexy.” “I would never wear anything with a saying so loud so I wanted to make it very subtle,” says the environmentalist, who also uses bamboo in her sophisticated high-end collection, due out in the fall. Emily VanCamp, for one, was sold on the message: “I think it’s fabulous! I bought a cardigan. I’m all for a healthy environment, healthy clothes.” Other celeb fans: Anna Faris, who hosted the party, Amy Smart, Heather Graham, and Alexx Jae’s childhood BFF, Nicole Richie. “Nicole wears my stuff. She has to!” says the designer, who will donate 100% of the proceeds to EMA. Click here to buy the t-shirts, $75, at shopatmilk.com.
