I know this is going to come as a shock to you all, but someone needs to speak the truth. It seems that environmentalists have a bit of a reputation for being holier-than-thou -- even, dare I say it, evangelistic. In our zeal to save the planet, we both scare and bore our fellow citizens, who see us as righteous beyond reason. Spring is here -- is your conscience clear? This is bad form, and bad politics. So let's try something new: Let's share our humanity. Perhaps we can endear ourselves to the congregation by admitting our eco-sins -- moral …

Environmentalists have a reputation for being self-righteous, holier-than-thou prigs. And yeah, well, they frequently are. So in the spirit of humanizing and soul cleansing and all that, we've asked a few greens, including writers Bill McKibben and Terry Tempest Williams, to confess their environmental sins. And we're asking you to do the same! Leave your deepest, darkest environmental sins in comments. We promise, you'll feel better afterward.

What work do you do? I produce films and other media about the environment.

All signs on Capitol Hill point to a royally depressing Earth Day 2005 (that would be next Friday): inertia on global warming, revival of the industry-friendly energy bill, a widely reviled plan to address mercury pollution, the looming prospect of drilling in the Arctic National Wildlife Refuge. And though it's the 35th anniversary of the first Earth Day, D.C.-based environmental groups don't seem to have plans for splashy protests or pep rallies to mark the occasion. Matt Damon. Photo: PBS. Could it be that an infusion of star power from Hollywood is the best hope for pumping new life into …

Survey reveals truth to tree-hugging Californian stereotype It is often said that Californians are unfairly stereotyped as bleeding-heart tree huggers. Turns out it's not true. The "unfairly" part, that is. A new survey reveals that more than 60 percent of Californians really have hugged trees, some 24 percent have surfed, and 21 percent think mud baths are totally rad. A questionnaire compiled by marketing professor Dennis Tootelian of Cal State, Sacramento, asked 500 folks from five California cities -- Los Angeles, San Francisco, Fresno, Sacramento, and San Diego -- about their true nature. Kevin Starr, author and former state historian, …

You could probably guess that Prius drivers tend to be Democrats and Hummer drivers tend to be Republicans. But that's just the tip of the iceberg on car-and-driver political connections, writes John Tierney in The New York Times, summarizing new market research that I find both fascinating and hilarious.   Jaguars, Land Rovers, and Jeep Grand Cherokees are very "Republican" vehicles. Volvos are the most "Democratic" cars, followed by Subarus and Hyundais. (Funny comment from Slate columnist Mickey Kaus: "Subaru is the new Volvo --that is, it is what Volvos used to be: trusty, rugged, inexpensive, unpretentious, performs well, maybe …

Dear Umbra, Twenty years ago, I lived off the grid and learned how to conserve water. That lesson stayed with me, and it's agonizing for me to witness the cavalier, wasteful treatment of precious freshwater. My elderly mother moved in with me two years ago, and all is lovely and fine, except that she wastes more water with basic household activities than any single individual I've ever seen. Do you have any suggestions on household water conservation? While many water-saving methods are obvious to me, they have escaped my mother's attention, despite my not-so-subtle hints and suggestions. Thanks for any …

Cameron, Arnold lead brigade of celeb eco-spokesfolk What formative experiences led to movie star and galactic hottie Cameron Diaz's commitment to the environment? "Nothing, dude. Life! Life!"

On upcoming episodes, rapper DMX will go camping in Yellowstone and Diaz boy toy Justin Timberlake will demonstrate his beat-boxing skills to Masai tribe members in Kenya. My god, our brains might explode with …

Robyn Griggs Lawrence. What's your job title? Editor in chief, Natural Home & Garden magazine. How does it relate to the environment? Working under the tagline "Living Green, Living Well," our magazine's mission is to show mainstream America that living lightly doesn't mean giving up a thing -- that they don't have to go live out in the hills in a yurt or a home built out of mud -- and that in fact there's a lot to gain by creating an environmentally friendly home. We want everyone to see the benefits -- what's in it for them -- of …

Biofuel catching on in the home-heating arena Using biofuel -- a mix of vegetable oil and diesel -- to power vehicles is already popular in certain highly vocal circles, but using biofuel to heat homes is just starting to catch on. A recent surge has taken place largely in the U.S. Northeast, where there remains a large concentration of houses that use heating oil. Proponents tout the fact that biofuel produces far less soot and thus requires less furnace cleaning, which we're told is a nasty business. They are also motivated by a desire to support energy independence and the …
