Big dairy farms produce more than just milk. They also generate manure. Lots and lots
of it. That can be a problem for farmers and the environment. Todd Melby reports on a
technology that reduces manure and generates electricity:

(sound of suckling cows)

I’m on a dairy farm with John Vrieze and his daughter Brittany.

Oh, and some cows too.

Vrieze is a frugal man. A couple of winters ago, he had a contest with his son to see who
could use the least electricity. Vrieze was willing to go to extreme measures.

His daughter Brittany tells the story this way:

Brittany Vrieze: “He’d shut his fridge off in the winter time. Just use the outdoors for his
fridge. He was definitely trying to keep the kilowatts down.”

Todd Melby: “So what did he do? He just kept his milk in the porch?”

Brittany Vrieze: “Yup.”

Todd Melby: “And kept his frozen stuff outside?”

Brittany Vrieze: “Yup. Yup.”

Today, Vrieze isn’t just trying to save energy. He’s trying to create it.

(sound of cow moos)

From cow dung.

He’s got 1,600 head of cattle at his place here in western Wisconsin. Those cows produce
milk that gets made into cheese. But they also produce about 50,000 gallons of manure
— every day.

Farmers are required to store that manure in a big pool-like structure called a lagoon.
John Vrieze covers his up with a giant tarp.

“It would blow up from the biogas. It would look like a great big balloon or like the
Metrodome, for folks in the Cities. It’s from the nature decomposition of the manure. It
creates biogas. We would have to take that gas out from underneath the cover and flare it
off, which got us to thinking that there has to be a better way to use that energy than just
to flare it off.”

So Vrieze bought a $1 million machine called a digester. And he had help from the
federal government. They paid for a quarter of it. The government is interested in these
things because they can turn manure into energy.

And it turns out — the reason it’s called a digester — is a farm thing.

“A cow has four stomachs. We call the digester really the fifth stomach. All the stuff that
comes out of the back of the cow we then put in that digester.”

So this “fifth stomach” produces energy. However, it’s not ready-to-use energy. To sell it
as natural gas, it has to be about 95% methane. The gas from the digester is only about
60% methane.

(sound of pipeline burn off)

Another option is to convert it to electricity. But in the U.S., electricity is cheap.

Todd Melby: “You tried to sell it to the electric company, but they didn’t want it.”

Brittany Vrieze: “They’re not offering us enough money. So …”

After all this investment by Vrieze and the federal government, some of the gas he
collects is just being burned off into the air.

But maybe not for long.

Vrieze wants to build a greenhouse right on his Wisconsin farm so he can grow
vegetables and herbs in the winter. He says he’ll power it with energy from the digester.

“So, instead of your produce coming from 2,000 miles away – from the central valley of
California – wouldn’t it be neat if it came from 45 miles away?”

Vrieze is planning to use the water from the cow manure for his vegetables and herbs in
his greenhouse. And he’s got a machine similar to ones used at wastewater treatment
plants to clean the manure water.

But even with the digester, there’s still leftover manure he has to deal with. But Vrieze
says the digester makes it more manageable.

(blowing sound)

Some of the dry manure is blown into a pile where it’s gathered up and used as bedding
for the cows. In the summer, it’s also used for another purpose.

“It’s just a clean version of manure. It stinks a little bit. Most of the stink has been taken
out of it. And we mix this with potting soil and it works great for the plants. So …”

That manure/potting soil mix is sold to gardeners in the city. It’s another way for Vrieze
to be frugal and environmental at the same time.

During the past couple of centuries,
the typical graveyard hasn’t changed
much. Its central features still include
tombstones, winding paths, trees and
grass. Some critics want cemeteries to
ban tombstones, stop fertilizing, and
institute other green practices. Todd
Melby reports that traditional burial
practices die hard:

I’m in a mausoleum with Roman Szabelski. He’s the head of Catholic Cemeteries for the
Archdiocese of Chicago. He’s punching information into a computer.

Catholic grave locator: “Spell out the last name of the deceased that you are trying to
locate using the touch-screen keyboard …”

“So I’ve just keyed in my family name and I’m pushing search. Florence Szabelski is my
mother so I’m asking it to show that record to me.”

Szabelski started mowing grass at the cemeteries in 1979. Today, he presides over 2.2
million dead at 43 cemeteries. That makes Catholic Cemeteries one of the nation’s largest
graveyards.

Other than the high-tech grave locator, Szabelski says his customers prefer things the old
fashioned way.

“We come from a very conservative tradition where people want their 3 by 8, their grave,
to look like their backyard, which is perfectly manicured.”

Some people would like to change that. Advocates of something called green burial say
the perfectly manicured grass, the granite tombstones, the concrete burial vaults, the big
wooden or metal coffins, all of it, is wasteful.

Instead, they’d like to see graveyards filled with native grasses and flowers, rocks used as
grave markers, biodegradable coffins or no coffins at all.

So far, there’s not much demand for green burial.

Most people here are like Charlene and Margaret Villarreal, who are sitting near their
mother’s grave at Queen of Heaven Cemetery. Until her mother’s recent death, Margaret
Villareal had no reason to visit a cemetery.

“I’m 45 years old and nothing has brought me to the cemetery. Nothing, until she passed
away.”

The Villareals have decorated their mother’s grave with red roses, a crucifix festooned
with purple ribbons and a Chicago Cubs pennant.

On this day, they’ve come to honor their mother’s birthday.

Charlene Villarreal: “I’ve planned it since the day she died. I knew I would be here.”
(long pause)

Margaret Villarreal: “Oh get a grip. If she were here …”

Charlene Villarreal: “Sorry, Ma. It’s not as bad as it was on Mother’s Day. (Pause)
(Sniffles) I’m OK.”

They chose a traditional funeral for their mother. Her body was embalmed, which
allowed for an open casket. That casket was placed inside a concrete vault and buried. A
grave marker notes that she was a “loving wife and mother” who will always be in the
hearts of her family.

Margaret Villareal fears a green burial would have robbed her mother of the respect she
deserved.

“Here we are. We’re in the United States. That’s traditionally not how it’s done. You
might do that with animals. But as humans go there is more of a process of dignity
involved. You know, it sounds like that’s something you would do in a mass burial with
some kind of a tragedy like the Chicago fire but not something you’d do to remember
your loved one.”

Environmentalists dispute that. They say most people simply don’t know enough about
green burial to make an informed decision.

Whether that’s true or not, Roman Szabelski of Catholic Cemeteries is plowing ahead
with his plans. He’s got plenty of land on hand for tomorrow’s dead.

“We’re sitting in Queen of Heaven Cemetery right now, which is roughly about a 300-
acre site. About 100 of those acres are leased to the golf course next door. As we need the
property, the golf course will go from 18 to 9 to zero and a driving range and that
property will be used.”

When Szabelski adds up all the land Catholic Cemeteries owns, he figures it can keep
doing business as usual for the next 100 to 200 years.

Memorial Day is coming up. Many people still visit the graves of family and friends,
maybe bring flowers. When a loved one dies, grieving prevents most of us from
thinking about the environmental consequences of conventional funerals and burial.
But some people are beginning to weigh the environmental costs of caskets, burial
vaults and grave markers. Todd Melby reports on the green death movement:

Amy Weik works at a bank in downtown Chicago. She’s also a big-time
environmentalist. She bikes to work, doesn’t eat meat, recycles and she composts.

“This is my worm bin. It’s a rectangular cube, which I keep my worms in that eat
my scrap vegetables. Mmm, look at that. Yum. Scrap paper, food that went bad.”

The environment is such a big part of Weik’s life, she’s not only interested in
living green.

She wants to die green.

“We’re Americans. We are wasteful and we consume. We think that we are
entitled to everything. So I’m entitled to using up this massive plot of land for the
rest of eternity. That’s ridiculous thinking. You know what I mean?”

So 11 years ago — when she was only 23 — Weik wrote her own will and shared it
with her mother.

Weik: “I can read part of it.”

Melby: “Sure, what does it say?”

Weik: “Zero products or services from funeral homes are to be utilized.”

Instead, Weik prefers her body to be chemically cremated. But that new, high-
tech process isn’t widely available yet. Her second choice is to be composted with
worms.

“If all efforts have been exhausted, but these two options are not available, please
bury me in a green burial ground, location unimportant.”

That second option leaves Weik’s mother — Linda Williams — confused.

“The second was composed with worms? When I read it today, my first reaction
was, oh my Gosh, she composts with worms in her kitchen. I hope she doesn’t
expect me to put her in the box!” (Laughs)

Weik sees lots of unnecessary waste in conventional burial practices. Caskets
constructed from wood or metal are used for a short time and then go right into
the ground. Most graveyards require the casket be placed inside a concrete burial
vault to prevent leaking, but most eventually leak anyway. Grave markers are
often made of granite. And cemeteries are usually manicured to perfection using
fertilizer and riding lawn mowers.

Green burial advocates prefer biodegradable caskets — or just a shroud — no
burial vault, no grave markers and no landscaping. They prefer natural
surroundings.

Weik is hoping to live long enough to see a cemetery in her town go green.

So far, that’s not happened.

But one organization is working on it.

“I don’t think many people really want many aspects of conventional death care. I
think they think it’s legally required.”

That’s Joe Sehee. He’s head of the Green Burial Council.

“Most Americans do not know that you can have a funeral with a viewing without
embalming. Most don’t know that you can transport a body across state lines
without having to embalm it. Most don’t know that burial vaults can be avoided,
for example, or that you can go into the grave with a shroud or nothing at all.”

The council has been busy certifying all kinds of earth-friendly death products,
but has been slow to find graveyards willing to ban concrete burial vaults and
minimize traditional landscaping.

That leaves Amy Weik wondering if she’s going to have rely on the worms in her
compost bin to dispose of her body.

When businesses begin offering
earth-friendly alternatives to
traditional products, it often
takes a while for those items
to catch on. The funeral industry
is no exception. Todd Melby reports
on one undertaker’s attempt at
greening death:

Steve Dawson is an undertaker who lives above his funeral home business.
His backyard looks like many here in suburban Chicago. It’s full of cherry
trees and apple trees and he’s got one of those round, above ground
swimming pools. Next to the pool, there’s a small building that looks like a
two-car garage.

We step inside.

“This is the crematorium. This is a cremation retort. As you can see it’s a
fairly large machine.”

That retort is a big furnace. It’s also a big part of Dawson’s business here at
Sax-Tiedeman Funeral Home.

Dawson: “We have a body that has been dropped off here for cremation. If
this is bothering you because we have a body here, I will do what I can to
get the body out of the way.”

Melby: “No, I’m fine.”

Dawson: “We’ll go back over here and get this started.”

(sound of the crematory furnace)

“That starts out the blowers, which is a purging blower, to basically clear
out anything that might be in the way there.”

After the furnace starts, it takes about two hours to finish the process. Then
Dawson takes the remains over to a machine that sifts through what’s left.

Dawson: “What we do is we go through there and sort through the
cremated remains.”

Melby: “This is actually what happens at the end, obviously.”

Dawson: “Right.”

Dawson collects all the prosthetics, those titanium knee and hip joints, in a big
can nearby. They get recycled.

That’s important to Dawson. At home, he’s a passionate recycler of soda pop
cans, newspapers and other household items.

“My family calls me the recycling Nazi because I get after them to put it all gets
put in the recyling bin.”

On the job, he tries to be green too.

Dawson knows that cremation — an option chosen by nearly 1 in 2 Americans —
has environmental downsides. Many older people have mercury dental fillings.
During cremation, that cancer-causing toxin vaporizes and goes up into the
atmosphere. Heating up the cremation furnace also eats up energy.

Dawson is also a savvy businessman. He believes more Americans are going
to want green choices, even when buying death products.

That’s why he’s embraced green burial. Sax-Tiedemann is Chicago’s first —
and so far only — green-certified funeral home. So in addition to selling
baseball-themed urns and big wooden caskets, Dawson has other choices
too.

“In this area here, we have rental caskets and up on the top, these are e-caskets,
Eco-caskets. These are made out of bamboo and these are designed to be
biodegradable.”

Although most Jews and Muslims skip embalming, the procedure is still quite
popular among Christians. Green death advocates are opposed to embalming
because of the formaldehyde used in the process. So to get certified, Dawson had
to buy a new machine.

“This is a three-body cooler. Inside a three-body cooler, this is what we use to be
able to hold remains without embalming. The temperature in the cooler is kept at
roughly 42 degrees. That’s enough to be able to slow down the decomposition
process.”

(funeral music)

A chilled body will hold for a day or so, which is usually enough time for friends
and family to gather and say good-bye. As baby boomers begin dying in big
numbers, Dawson expects more of them to choose green burial.

Getting People to Stop Burning Trash

Getting rid of your trash in the city is easy. Take it to the curb on pickup day and the city does the rest. In rural areas, many people don’t have garbage pickup. So they burn their trash. And that causes pollution. Todd Melby tells us about one place that’s trying to change its burning habits:


Robert Olsen lives out in the country. He used to burn his garbage. But not any more.


(Pickup hatch opens)


On this windy morning, Olsen has driven his pickup into town to dump his trash.


“I think this is probably a week’s worth for us.”


He grabs the blue plastic bin from the back of his pickup and dumps it into a green Dumpster.


“Not too difficult.”


Olsen runs the environmental office here in Lincoln County, Minnesota. It was his idea to set-up nine Dumpsters throughout this sparsely populated county. He did it because he knows that burning garbage pollutes.


“The issue is that when you burn garbage at home, in the country, the first people or persons who are going to experience any harmful effects from that garbage are going to be you.”


That’s because a lot of trash — including even plain old paper — contains chlorine that produce dioxins when burned at home. Plastic is even worse.


Mark Rust is a solid waste expert with the Minnesota Pollution Control Agency.


“If you’re using a burn barrel or fire pit or you’re burning garbage in any way on your own property, you’re creating a perfect factory for producing dioxins.”


Smoke from burn barrels and fire pits are now the leading source of dioxins in air pollution. Some studies have connected dioxins to cancer. Burning garbage is especially bad because there are no anti-pollution scrubbers on do-it-yourself burners.


“With a burn barrel, it’s all right there.”


Melby: “It all just goes right up into the air?”


“Into the air, into the soil. Ultimately, we’re going to be taking it in on the dinner table.”


Most states still allow people living in the country to burn their garbage. In Minnesota, only farmers and those without access to affordable garbage pickup can burn. A 2005 survey found that about half of the people living in rural Minnesota burn at least occasionally.


Which is why the state offered rural counties some start up money to get people to burn less.


Rural residents in Lincoln County, Minnesota have had access to drop-off sites for seven months now. When the program started, haulers took away about 8 tons of trash every month. Now it’s up to 15 tons.


Back at one of the county’s drop-off sites, Clarence Lietz is getting of his Buick and grabbing newspapers for the nearby recycling bin. What doesn’t get recycled, gets burned, he says.


“What garbage we have like small things for the yard we just burn right at home, you know. I’d say about a five-gallon pail full or something like that.”


Another elderly customer — she didn’t want her name used — says she burns junk mail and envelopes at home.


“Papers. That’s all you can burn. I don’t burn garbage.


Melby: “And why don’t ya?”


“It’s not right to burn garbage. It don’t burn any good anyway.”


Melby: “Why isn’t it right to burn it?”


“You know why, don’t cha?”


I do now.

Osprey Nest Near Fish Hatchery

Ospreys are birds of prey that eat fish. Todd Melby tells us
about a pair of osprey that tried to nest near a fish hatchery:

The osprey is a raptor that scoops fish out of rivers and lakes.

So when a pair of osprey decided to mate near a DNR fish hatchery south of
Minneapolis, biologists were delighted and worried.

Ospreys rarely nest so far south. So that was good news. What worried biologists was
whether the birds would eat the fish. Biologists decided these fish were too small.

Another worry was the ospreys’ choice of a nesting site. In this case, the birds picked an
electrical power pole.

Lisa Gelvin-Innvaer is with the Minnesota DNR.

“They like high areas. Places that have room for them to put their nest. Transmission
poles often provide that.”

Biologists decided that was a bad idea, so they’ve built a tall nesting platform near the
power pole.

“We’re hopeful with the new nesting platform, that they’ll come back and attempt to nest
again.”

Car Sharing Gets Profitable

private companies, Zipcar and Flexcar. Now, those firms are poised to
expand their operations. The Great Lakes Radio Consortium’s Todd
Melby has this report:


For the past six months, a nonprofit called the Neighborhood Energy
Consortium has had the Minneapolis/St. Paul car sharing market to itself.
The non-profit group has raised about $450,000 to buy 12 cars. Those
energy-efficient hybrids have attracted about 140 people to join the
HourCar program. That’s Hour with an “H.”


(Sound of bus stop and rumble of passing truck)


On this Saturday morning, Mary Solac is shivering at a bus stop, waiting
for a ride to go pick up her HourCar. Despite the obvious inconvenience,
she says it’s worth it.


“You don’t have to worry about insurance. You don’t have to worry
about gas. It’s like okay, I’m paying what I’m paying and I don’t have to
worry about fixing the blasted car either.”


After a short bus ride, Solac does have to worry about more mundane car
concerns… such as scraping the ice and snow off the window.


(Sound of ice/snow scraping on the windshield)


To date, Solac’s only choice for renting a car by the hour has been
HourCar. That’s about to change.


The nation’s largest car sharing company — Zipcar of Boston — is
invading HourCar’s Minneapolis turf. Nearly 50,000 people now take
turns driving about 500 Zipcars, mostly in Boston, New York and
Washington, D.C.


Scott Griffith is the CEO of Zipcar.


“Over the last several years, we’ve really focused on those cities and getting
them past profitability, past the break even point, to prove that at the
metro market level, that we can make money in this business.”


That track record enticed a venture capital firm to invest $10 million in
Zipcar.


Another big new company is also getting an influx of cash. The nation’s
second-largest car sharing company — Flexcar of Seattle — is about half
as big as Zipcar. It too has a new investor: AOL Founder Stephen Case.
He rented a Flexcar, liked it and bought the company.


In Chicago, Flexcar has paired with a local nonprofit to put 47 cars on
the street.


Zipcar, meanwhile, is also trying to get into Chicago. It wants
government agencies in the Windy City to commit to using its cars
before entering the market. The company hopes that happens sometime
this year.


Business professor Alfred Marcus at the University of Minnesota says it’s
not unusual for emerging businesses to seek government help like this.


“To get this sector going, to stimulate it, it makes sense for their to be
some public involvement, but you would hope this could take off on its
own. I think this is transitional – these public and private partnerships,
and that’s very typical when industries start.”


In Minneapolis/St. Paul, the University of Minnesota is guaranteeing
Zipcar a $1,500 per month per vehicle subsidy, but once Zipcar meets the
$1,500 minimum, that subsidy goes away. Zipcar says it expects to do
just that in three months.


At the moment, Zipcar is growing fast. It had revenues of about $15
million in 2005. CEO Griffith says it expects to double that this year, but
Alfred Marcus with the University of Minnesota says over the long-term,
Zipcar faces big hurdles.


Zipcar has only had success in large, densely-populated cities. Its target
market is young people without cars who are highly price sensitive, and
then there’s the question of where to keep the cars. They have to be
conveniently located to the people who might want to use them.


Marcus says that if these start-ups continue to grow, someday they might
be gobbled up by bigger companies.


“The ultimate aim of Flexcars or Zipcars may be to build up a fringe
business, get it going and have a rental car company buy them or have even
have a conventional automobile company by them.”


But the car-sharing company owners say they have other plans. Zipcar
boss Scott Griffith says he’s working on a 10-year plan to make Zipcar an
international company. Flexcar owner Stephen Case says he bought that
firm “to build it” and not to “flip it.”

Forecasting Monarch’s Future in Warmer World

Every winter, millions of monarch butterflies migrate from backyards in
North America to nestle in trees in Mexico. The weather conditions in the
mountains there are perfect for the insect. But scientists say climate change could
spell disaster for the species. The Great Lakes Radio Consortium’s Todd Melby has
this report:


The fir trees in central Mexico are ideal conditions for the monarch
butterflies of North America to spend the winter. The habitat there is cool
and dry.


“They are looking for a refrigerator.”


That’s Karen Oberhauser, a researcher at the University of Minnesota. She
Says the orange-and-black-speckled butterflies spend up to five months there
Before coming north again.


The new study was published in the Proceedings of the National Academy of
Sciences. It shows that the biggest threat to the monarch’s Mexican habitat
may be an increase in rainfall. She says that would cause the monarchs to freeze
to death.


“It’s worrisome to me that, in a sense, we humans are kind of conducting this huge experiment and
we don’t know the outcome.”


The long-term climate change could force monarchs to flutter off in search
Of new places to winter. She says if they fail, the results could mean the end
of a species.

Endangered Mussel Rides to Renewal

  • Biologists release bass, gills laced with Higgin's Eye Pearly Mussel larvae, into the Mississippi River. Photo courtesy of the Minnesota Department of Natural Resources.

Up and down the Mississippi River, people once collected tons of mussels for the pearl button industry. Factories stamped out pearl buttons from the shells, sometimes wiping out 50,000 tons of mussels annually in the early part of the last century. In recent years, the biggest threat to local mussel species has come from the zebra mussel. That invasive species came to North America in the ballast water of ships and has since disrupted many local ecosystems. Today, there’s a new effort underway to bring back local species like the Higgin’s Eye Pearly Mussel, and it’s in an unlikely place. The Great Lakes Radio Consortium’s Todd Melby has this report:

Eye Pearly Mussel. And it’s in an unlikely place. The Great Lakes Radio Consortium’s
Todd Melby has this report:


Urban areas like Minneapolis-Saint Paul might seem like an unusual
location to boost the population of an endangered species.


But it’s here, below a busy bridge that spans the Mississippi River, that
biologists are searching for a safe place for their project. Divers have
just come up from the bottom of the river with a few mussel specimens.


“Well, we’ve got Big Toe, Maple Leaf, Three Ridge. Good enough I think.”


That’s Mike Davis rattling off the names of mussel species. Davis is
a biologist with the Minnesota Department of Natural Resources. The fact that
some mussels live in this part of the river makes Davis think that this
might be a good spot for the Higgin’s Eye. The Higgin’s Eye, which has an olive-
colored shell, has been languishing on the Endangered Species List since
1976.


Just two decades ago, this part of the river suffered from sewage runoff. The river is cleaner now and some mussels have returned. But not the Higgin’s Eye. And that has Roger Gordon worried. He’s a biologist with the U.S. Fish and Wildlife Service.


“They function as the kidneys of the river, more or less. They siphon everything that
goes through the river. They are a very good indicator species if we have a problem in the environment. They are usually the first species to get hit hard and disappear.”


For the past decade or so, it’s been the zebra mussel that’s been hitting the Higgin’s Eye. But the zebra mussel hasn’t made it to this part of the river. That’s why biologists are on a small flotilla of boats on this morning with 800 large-mouth bass. The bass and the Higgin’s Eye have a strong connection. Attached to the gills of those bass are thousands of Higgin’s Eye larvae.


“Right now, we’re counting fish in the cage. We have a known number of fish, 25 in
this case, that we’re going to place in these cages. And hopefully over the next several weeks, they’ll drop off and we’ll have clams in the river.”


Melby: “You’re putting them in the bucket?”


“Right now we’re putting them in a bucket and placing them in the cage over the
side of the boat.”


(sound of buckets banging and water sloshing)


The bass are put in cages so they don’t swim somewhere that’s not a good home for the Higgin’s Eye. In the wild, adult females mussels shoot embryos at unsuspecting fish swimming overhead.


“The larvae have a chemo-receptor in them. When they touch flesh, they actually shut. It’s a one-shot deal. If that fish clamps on a fin or an eyeball or a lip, it’s a no-go. He’s not going to develop. But if he’s lucky, and he just happens to be going through a gill arch of a fish and it’s the right fish, the right species of fish and the right size fish, it
will shut on that gill.”


But the Higgin’s Eye population is too low to leave to chance.


(Bubbling sounds of fish hatchery)


So Gordon and his colleagues bumped up the number of mussel larvae
per fish here at a federal fish hatchery in Genoa, Wisconsin. Instead of just a
few larvae per fish, the bass dropped into the Mississippi have several dozen
larvae attached to their gills.


That prep work took place inside the “Clam Shack,” which is really
just a metal pole barn that biologists built themselves.


“We didn’t have any money to do this. We scraped up and saved up at the end
of the year. We had seven or eight-thousand dollars. The hatchery guys just got together and built this little building.”


Since beginning their work two years ago, they’ve added approximately
12,000 mussel-rich fish to rivers in Wisconsin, Illinois, Iowa and Minnesota.


“We’re probably going to have to build another little building
like this. But we’ll scrape along and do what we can.”


Back on the river, Mike Davis of the Minnesota DNR calls the return
of the Higgin’s Eye historic. But with the zebra mussel closing in on native
mussel species like the Higgin’s Eye, he’s also a bit wistful.


“The former dead zone of the Mississippi may become
one of the last refuges for the Mississippi’s mussel species.”


In September, divers return to that same spot to check on the Higgin’s
Eye. They hope to find thousands of young clams nestled safely in their new
home. For the Great Lakes Radio Consortium, I’m Todd Melby.

Cracking Down on the E.L.F.

The Earth Liberation Front is an underground group that attacks institutions it believes harm the environment. During the past five years, its members have caused approximately $40 million in damages. E.L.F’s most notorious acts of destruction include torching a luxury ski resort, destroying the executive offices of a forest-product company, and setting on fire university labs involved in genetically-modified crop research. For some time, environmentalists and others have debated whether this sort of activity was simply a public protest, or acts of terrorism. But since September 11th, that debate has escalated with increased efforts to label those involved in such attacks as terrorists. The Great Lakes Radio Consortium’s Todd Melby has this report:

The Earth Liberation Front is an underground group that attacks institutions it
believes harm the environment. During the past five years, its members have caused
approximately $40 million in damages. E.L.F.’s most notorious acts of destruction include torching a luxury ski resort, destroying the executive offices of a forest-product
company, and setting on fire university labs involved in genetically-modified crop research. For some time, environmentalists and others have debated whether this sort of activity was simply a public protest, or acts of terrorism. But since September 11th, that debate has escalated with increased efforts to label those involved in such attacks as terrorists. The Great Lakes Radio Consortium’s Todd Melby has this report:


On a cold, January night in St. Paul, Minnesota, one or more members of the Earth Liberation Front set fire to a construction trailer parked on the University of Minnesota campus. Flames quickly spread to an adjacent building, causing $40,000 in damages.


(Construction site sounds)


But while the Crop Research Building burst into flames, the real target was the university’s proposed Microbial and Genomics building – a $20 million undertaking.


(Construction sounds go silent)


The attack wasn’t a surprise to Peggy Leppick. She’s a state representative, who chairs the Higher Education Committee in the Minnesota House of Representatives.


“A lot of the research that goes on at the university is fairly obscure and people don’t know about it, but when you build a building that is essentially a monument to genomics and genetic engineering, it becomes a bulls-eye.”


That’s why university officials are asking the Legislature for nearly $4 million to beef up security. They’ve also ratcheted up the rhetoric. University of Minnesota president Mark Yudolf has no qualms about using the word “terrorist” to describe E.L.F. members who’ve attacked his campus more than once.


“People who blow up facilities and buildings and who may try to avoid risking human life, but almost inevitably something can go wrong: that is my definition of a terrorist, yes.”


But attaching labels to actions doesn’t come so easily for others. There’s a fine distinction for some between terrorist and protesters.


“The definition of terrorist is a very political definition.”


Katherine Sikkink is a political science professor at the University of Minnesota.


“In this country, we have words for it. It’s called ‘crime.’ We don’t have to jump to the term ‘terrorism.’ When people destroy property it’s called ‘crime.’ We have police forces that are here to deal with crime and I think they should do it.”


Not surprisingly, Leslie James Pickering, a spokesman with the E.L.F. press office in Portland, Oregon, agrees with Sikkink’s characterization.


“If they were terrorists they would be engaging in violent terrorist actions. What they do is sabotage property. They’ve never harmed anybody. They never will harm anybody because it is against their code.”


That code, Pickering says, ensures that human life will be protected. When E.L.F. activists set fire to a building, they say it’s searched before flames engulf the facility.


“They are vandals. They are arsonists. They are engaging in illegal activity, there’s no question about that, but there is a difference between sabotage and terrorism.”


But that distinction may be lost in the rush to deal with terrorism, both foreign and domestic. The government appears on the verge of adding environmental groups such as E.L.F to its “War on Terrorism.”


A top F.B.I. official has called E.L.F. “the most active eco-terrorist” group in the United States. A Congressional Committee recently subpoenaed Leslie James Pickering’s predecessor in the E.L.F press office to testify. When committee members weren’t satisfied with his answers, they threatened him with contempt of Congress.


And now U.S. Congressman Gil Gutknecht, a Minnesota Republican, is calling for the death penalty if politically-motivated arsons or other actions result in a fatality. Gutknecht also wants the federal government to establish an “eco-terrorism” clearinghouse so law enforcement officials can do a better job of tracking environmental activists involved in illegal activity.


These proposals have drawn the ire of Chuck Samuelson, the executive director of the Minnesota Civil Liberties Union.


“September 11 has been a boon for people who are interested in making laws more strict, regulating society and limiting freedom.”


Samuelson says Gutknecht’s death penalty proposal won’t stop politically-motivated murders. And he’s also opposed to a federal clearinghouse that tracks E.L.F. members, saying it’s likely to be secret.


“The question that always comes up is about the privacy rights of people, how that information gets put in, who gets to change that information and who gets to use that information. If it’s secret and is not available to the public, so that you as a reporter couldn’t go see it or do an investigative piece on how they’re doing it, it’s got to scare you.”


Although Samuelson is quick to criticize the government’s proposed crackdown on E.L.F., he’s no defender of the group. He scoffs at the E.L.F. code, saying no matter their ‘no-harm-to-human-life’ intent, it’s only a matter of time before someone is killed.


Professor Sikkink also questions the group’s tactics. While some protest movements have historically engaged in property damage to score political points, she says it comes with a high price tag.


“So these tactics, you know, of destruction of government property are not unheard of, they’ve been around for a long time, but I do think they really run the risk of alienating the people you want to convince.”


Despite the increased pressure on E.L.F to halt the violence, Leslie James Pickering, the group’s spokesman, says he doesn’t expect its members to change its ways anytime soon. For the Great Lakes Radio Consortium, I’m Todd Melby in Minneapolis.
