During the Reign of Dubya, the Left predicted a coming theocracy. One favorite bit of evidence was some far-flung school district adding creationism to its curriculum.

But the religion that is truly dangerous, to our minds, way of life and pocketbooks, is radical environmentalism such as this anti-capitalist video currently getting wide play in our public schools.

The thick-lined drawings of the Earth, a factory and a house, meant to convey the cycle of human consumption, are straightforward and child-friendly. So are the pictures of dark puffs of factory smoke and an outlined skull and crossbones, representing polluting chemicals floating in the air.

Which is one reason “The Story of Stuff,” a 20-minute video about the effects of human consumption, has become a sleeper hit in classrooms across the nation.

The video is a cheerful but brutal assessment of how much Americans waste, and it has its detractors. But it has been embraced by teachers eager to supplement textbooks that lag behind scientific findings on climate change and pollution. And many children who watch it take it to heart: riding in the car one day with his parents in Tacoma, Wash., Rafael de la Torre Batker, 9, was worried about whether it would be bad for the planet if he got a new set of Legos.

“When driving by a big-box store, you could see he was struggling with it,” his father, David Batker, said. But then Rafael said, “It’s O.K. if I have Legos because I’m going to keep them for a very long time,” Mr. Batker recalled.

Poor kid can’t get a toy without feeling guilty. Sin and guilt, sound familiar? And don’t forget piety, for all those who live greener than thou.

The video was created by Annie Leonard, a former Greenpeace employee and an independent lecturer who paints a picture of how American habits result in forests being felled, mountaintops being destroyed, water being polluted and people and animals being poisoned. Ms. Leonard, who describes herself as an “unapologetic activist,” is also critical of corporations and the federal government, which she says spends too much on the military.

Ms. Leonard put the video on the Internet in December 2007. Word quickly spread among teachers, who recommended it to one another as a brief, provocative way of drawing students into a dialogue about how buying a cellphone or jeans could contribute to environmental devastation.

So far, six million people have viewed the film at its site, storyofstuff.com, and millions more have seen it on YouTube. More than 7,000 schools, churches and others have ordered a DVD version, and hundreds of teachers have written Ms. Leonard to say they have assigned students to view it on the Web.

Alas, capitalism has no champion, no spokesman, no priest.

China figured out that market economies are the engine of wealth. Someone should make a video demonstrating the difference between China now and China in 1985.

There is a glimmer of hope.

Mark Zuber, a parent of a child at Big Sky High School in Missoula, had a stronger reaction when a teacher showed the video to his daughter last year. “There was not one positive thing about capitalism in the whole thing,” Mr. Zuber said.

Corporations, for example, are portrayed as a bloated person sporting a top hat and with a dollar sign etched on its front.

He described the video as one-sided. “It was very well done, very effective advocacy, but it was just that,” he said.

Mr. Zuber argued before the Missoula County School Board that the way in which “The Story of Stuff” was presented, without an alternative point of view, violated its standards on bias, and the board agreed in a 4-to-3 vote.

Still, Ms. Leonard is hoping the video will circle the globe. “I’ve heard from teachers in Palestine and Papua New Guinea,” she said. “It is just spreading and spreading.”
