AARON ROURKE
CLEANS UP ECOHAZARDS

AGE 44

OCCUPATION
Industrial hygienist, who tests workplaces to ensure they're safe from toxic substances

LIVES IN
Springboro, Ohio

HOW HE'S GREEN
"I pick up trash everywhere I am," says Rourke, whose Christmas wish list included a trash-grabbing tool like those used to clean up roadways. "If I set the example, other people won't think it's strange to do something like that."

ENVIRO-ASSETS
"Women say they like my sense of responsibility," says Rourke, who's also a booster for recycling and against drinking bottled water. "The fact that I'm an activist—that's been attractive."

BILL SCHENK
GUARDS THE RIVERS AND FISH

AGE 40

OCCUPATION
Attorney for the Montana Fish, Wildlife & Parks agency
LIVES IN Helena, Mont.
HOW HE'S GREEN
Schenk hangs his laundry to dry, makes his own compost and recycles everything, right down to the liners in his cereal boxes (they make excellent pooper-scoopers for his dog, Carmen). "I lead a very low-consumption lifestyle," he says.

PERFECT DATE
"For me it would involve an entire weekend. On Friday we'd run out to a trail, camp out. On Saturday, we'd hike the mountain, come back down in the late afternoon and then find a good place to watch the sunset."

TOM BALLANCO
SAVES THE FORESTS

AGE 39

OCCUPATION
Environmental lawyer

LIVES IN
San Rafael, Calif.

HOW HE'S GREEN
"Being green informs all my actions—the food I buy, the vehicle I drive, the relationships I have," says Ballanco, who helped fight to save redwoods in Mendocino, Calif. He grows much of his own food, uses candles instead of electric lights when possible and tries to live in "off the grid" homes (ones that don't use commercial power).

DATING PITFALL
"If a date doesn't understand that I'd go to three different stores in my search for the right recycled paper, that could be a factor."

GUILLERMO PAYET
HELPS LOCAL FARMERS

AGE 43

OCCUPATION
Founder of www.localharvest.org, a Web site that promotes buying food from nearby farms

LIVES IN
Santa Cruz, Calif.

HOW HE'S GREEN
"I wash my hair with handmade soap. Sometimes I even brush my teeth with it. I like to keep chemicals away from my body."

DATING NO-NO
"I've had girlfriends who wear a pair of jeans once and wash them immediately. I'm like, 'You're polluting the water and wasting electricity.'"

TED MILLER
PROTECTS WILDLIFE

AGE 28

OCCUPATION
Marketing analyst at the World Wildlife Fund

LIVES IN
Bethesda, Md.

HOW HE'S GREEN
He picks up trash in parks, helped start a garden at a school and doesn't own a car: "I feel better walking. And you get to know your environment better."

ECOCHIC
"I'm always walking around in a World Wildlife Fund T-shirt. It's baby blue with a big panda. It's not the most masculine thing, but women think it's cute."

DAVID DE ROTHSCHILD
FIGHTS GLOBAL WARMING

AGE 28

OCCUPATION
Author of The Live Earth Global Warming Survival Handbook, out this month

LIVES IN
Leighton Buzzard, England

HOW HE'S GREEN
"I grow my own vegetables," says de Rothschild, heir to a banking fortune. He also bikes to get around his rural town (he doesn't own a car) and in 2009 plans to sail across the Pacific on a boat made from recycled plastic bottles. "The message is about the amount of trash in our oceans," he says.

DATING DEALBREAKER
"I'd never push my ideologies onto someone," he says, "but I probably wouldn't date somebody who runs around in a private jet."

SEXIEST WAY TO CONSERVE WATER
"I love baths," says de Rothschild. "But I try to share them—that's a good ecotip!"
