A film about food waste is catching attention and awards at independent film festivals across the country.

The film’s called “Dive!,” and reviewers are shocked by the film’s statistics about how much edible food that grocery stores toss into dumpsters.

Shawn Allee reports the reviewers are also enthralled by the filmmaker’s personal story about diving after that food.

Jeremy Seifert didn’t start dumpster diving to make a film.

A few years ago, friends turned him onto it.
One morning, they surprised him with bags of food pulled from a dumpster.

“And so my entire kitchen floor was covered with meat and salads and I was filled with delight and wonder and I just said, “where do we begin?”

Seifert says he dumpster dived for kicks, but that changed.
Seifert is a filmmaker by trade, and he got a filming assignment at a refugee camp in Uganda.
The kids in the camp had hardly any food.

“They were truly hungry and suffering from hunger. And I came back home and two nights later, I was on my way to a dumpster pulling out a carload of food that had been thrown away. That experience filled me with such outrage, that I felt I needed to do something and my expression was to make a film.”

Seifert’s film picks up after his dumpster diving takes this kind of political turn.
It’s not for kicks anymore; he wants to show our food waste problem is so bad, that his family could practically live off food from grocery stores dumpsters.
He gets advice from experienced divers.

“Rule number one. Never take more than you need unless you find it a good home.”

But, Seifert runs into trouble with this rule.
He can’t let food go …

“I’m tired of it, there’s too much. I only took this much because there’s so much going to waste. It’s almost two in the morning, and I don’t have anywhere to put it, really.
I had to save as much of it as I could. In just a week of nightly diving, we had a year’s supply of meat.”

Guilt wasn’t his only problem.
His wife, Jen, explains a practical one.

“The dumpster stuff is really great. but because there’s such a large quantity of it, it can turn to a lot of work. So there’s like 12 packages of strawberries that I need to wash and freeze and cut. It’s not that big of a deal, but it’s just a lot more work than going to the grocery store and picking up just what you need.”

Seifert says the biggest problem with dumpster diving, was that it changed how he felt about food. One morning, he talked to his young son about it and kept the camera rolling …

“I don’t know if dumpster diving and eating food from the dumpster has made me value food more or value food less because it’s easier now to throw food away because we have so much of it. Part of me, I think I’m valuing food even less.”

“You can’t waste food, Dad.”

“I know, I don’t want to waste food. Do you want to waste food?”

“No.”

“I don’t want to waste food, either.”

Seifert tells me that this scene at the breakfast table haunted him, because maybe he was setting a bad example for his son.

“So it was a crisis moment in my food waste dumpster diving adventures. And so by the time the film was over, I was so tired of food and thinking about food.”

Well, Seifert’s had to keep thinking about food.

His film’s at festivals, and he helps activists get grocery stores to donate to food banks.
But things have changed at Seifert’s house.

He doesn’t dumpster dive so much – instead, he’s started a garden.
That way, his boy can really value what makes it to the dinner table.

Diving for Cures

Making medicine from things
found in nature isn’t a new
idea. Think, aspirin – which
originally came from the bark
of willow trees. Now drugs
derived from ocean animals are
slowly making their way onto
shelves. Samara Freemark talks to a researcher
who helps get them there:

Mark Slattery is trying to find a cure for cancer. Slattery is a pharmacology professor at the University of Mississippi. But he doesn’t really spend much time in the lab. Instead, he’s usually in a wetsuit, scuba diving off the coasts of places like Guam and Antarctica.

He’s taking samples from tens of thousands of corals and sponges. He’s looking for that one special species that might make a chemical that could cure disease. He calls it, ‘diving for cures.’

“In many ways, it’s like going out and playing your super lotto or whatever. You pick your eight numbers and you see if you hit or not.”

The idea is pretty simple. A third of the medicines on shelves today were derived from plants and animals that live on land. So ocean researchers got to thinking that the organisms they studied probably also produced a lot of useful chemicals.

Take corals and sponges. They can’t run away from predators, so instead they squirt out chemicals that poison the fish that try to take a bite out of them. Marc Slattery says those toxins are bad for the fish – but they could be good for people.

“Those particular compounds that tell a fish “not today” are the same ones that might tell the AIDS virus “you can’t replicate” or tell a cancer cell “you’re dead” or those kinds of things.”

So Slattery and other researchers like him clip off bits of sponges and corals. When they get back to the lab they extract the chemicals, which is a nice way of saying…

“Stick it in a blender with methanol and ethyl acetate and hexanes and all those sorts of things you used in organic chemistry lab, and you throw away the dead sponge, and the tarry residue that’s left is sort of the biochemistry that came out of that sponge.”

“So you make a sponge smoothie?”

“Exactly.”

Once they’ve extracted the chemicals, researchers test to see if they have any human application. If a compound looks promising, it moves on to clinical trials. Those trials can take decades, which is why ocean-derived drugs are only now starting to hit the market. So far only two have been approved for use in the United States: a painkiller, and a cancer drug marketed by Johnson and Johnson.

I wondered how ocean conservationists felt about diving for cures. So I called up Sandra Brooke. She studies corals at the Marine Conservation Biology Institute. Brooke says she does worry that diving for cures could lead to over-harvesting.

“Once something becomes valuable to people, there’s a resistance to closing access to it. It becomes harder to regulate it.”

But she says corals are under much greater and much more immediate threats. The biggest culprit is industrial trawling. That’s when fisherman scrape reefs off the ocean floor so they can get to the fish.

“It’s just like the clear cutting of the forest, but on a much vaster scale. They are deliberately mowing down these deepwater coral ecosystems that are thousands and thousands of years old – some of the oldest animals ever measured. And that’s not going to come back – not in our lifetimes, not in many lifetimes.”

There’s also the fact that oceans are changing as the climate does. Those changes mean corals are becoming weaker. Marc Slattery thinks he might be seeing that in a Pacific reef he’s been studying for fifteen years.

“When we went back and started looking at it, we noticed that there was a change in the chemistry through time. As things have heated up on the reefs, there’s a physiological effect that has cascaded down into their ability to produce the chemistry we’re used to seeing. Early on it was so apparent, it was always there, and now they seem to be able to produce less of it.”

That’s means that today the cure for cancer might be out there in some coral reef, but it could be gone tomorrow.

Saving Underwater Forests From a Prickly Pest

  • A few years ago, urchins had mowed this huge kelp forest down to just a few square feet (Photo by Ann Dornfeld)

Most of the world’s forests are on dry land. But in a few special places on earth, forests grow underwater. They’re kelp forests. And they’re home to an astounding array of marine life. Trouble is, these underwater forests are vanishing. Ann Dornfeld reports on efforts to turn the tide:

Most of the world’s forests are on dry land. But in a few special places on earth, forests grow underwater. They’re kelp forests. And they’re home to an astounding array of marine life. Trouble is, these underwater forests are vanishing. Ann Dornfeld reports on efforts to turn the tide:

A healthy kelp forest is so thick with fish and invertebrates that you’d swear you were looking at an aquarium exhibit.

They’re biodiversity hotspots – places that feed and protect an extraordinary number of species.

Brian Meux of Santa Monica Baykeeper standing on the deck of a boat in his wetsuit. He’s looking proudly at a thriving kelp forest along a rocky coastline near Los Angeles.

“This is our little jewel on this coast. Not only does the kelp forest have over 800 species dependent on it, but more than a quarter of all California marine species are dependent upon the kelp forest during some part of their life cycle.”

Since the 1960s, Southern California has lost 90% of its kelp forests. The culprit looks like a small purple pin cushion.

It’s a sea urchin!

Urchins love to eat kelp, and their populations have gone out of control. That’s because overfishing has removed most of the large fish and lobsters that eat urchins.

A few years ago, urchins had mowed this kelp forest down to just a few square feet. So Meux and a team of Baykeeper volunteers are trying to restore the balance.

They’re licensed by the state to do “urchin relocation.”

“what we do is go down, collect urchins by hand, get them on the boat and relocate them to areas where they will no longer harm the kelp forest.”

Sounds easy enough.

“Some of them you’ll want to just pull off the reef – they’ll look like they just can come off – I recommend using the tool. Urchin spines in your fingers… just not fun. ”

Or maybe not.

Either way, it’s time for the us to gear up and jump in.

(sound of diving in and scuba breathing)

Twenty-five feet underwater, the ocean surges so violently that the divers cling to rocks so they won’t be swept away.

It’s tricky to find a safe rock to grab because most of them are covered in urchins that have moved in on this young kelp forest.

But urchins aren’t the only migrants.

Huge purple sheephead and fire-orange Garibaldi fish swim by. A small octopus sits curled in a crevice. Pastel sea stars are everywhere.

Four years ago, this site was pretty much just rocks and urchins.

Two dives later, the divers are back on the boat.

Diver 1: “That was a workout!”

Diver 2: “That was a workout. I’m tired.”

After the team hauls up bag after bags of purple and red urchins, we try unsuccessfully to extract a spine from one volunteer’s finger.

Next, we move to deeper water a mile away. This will be the urchins’ new home.

The divers count the prickly balls as they throw them overboard.

Diver: “Purple!”

Each time a diver counts ten urchins of a particular color, they call it out.

Divers: “Purple! Purple.”

Similar kelp restoration efforts have revived kelp forests along other stretches of the California coast. But while those projects involved reseeding of the kelp forest, Meux says Baykeeper focuses on urchin relocation.

“We’ve found that mostly just get rid of the urchins and natural kelp spores will seed the reef and the return of kelp will ensue.”

Diver: “Purple!”

In all today, the team has relocated about 1500 urchins.

Between weekly trips like these and giant kelp’s ability to grow as fast as two feet a day, kelp restoration is a
heartening environmental success story.

In order for Southern California’s kelp forests to make a widespread comeback, Brian Meux says the state will need to limit the fishing that caused this problem in the first place.

And that issue’s as prickly as an urchin.

Coral Conservation in the Caribbean

  • The island of Bonaire is somewhat of an anomaly in the Caribbean due to its remarkably preserved coral reefs (Photo by Ann Dornfeld)

Scientists say nearly half of the coral reefs in the US are in bad shape.
Many are dead. The situation is similar in much of the world. But not
everywhere, as Ann Dornfeld found on the Caribbean island of Bonaire:

Transcript

Scientists say nearly half of the coral reefs in the US are in bad shape.
Many are dead. The situation is similar in much of the world. But not
everywhere, as Ann Dornfeld found on the Caribbean island of Bonaire:

(sound of waves on shore)

Jerry Ligon was working as the on-board naturalist on a small Caribbean
cruise ship when he first saw Bonaire.

“And I saw how clear the water was. And I’d been able to compare, during
my stint on the cruise ship, other islands in the Caribbean, and I realized
how special Bonaire was. So that was at the end of my contract, so I
decided to stay here. And I’ve been here for 15 years!”

It’s wasn’t just the clarity of Bonaire’s water that made Ligon stick around. It
was the remarkably healthy coral reefs that lay beneath the waves.

“I can even talk to divers who come to Bonaire and they say, ‘What
fantastic diving!’ and they remember, ‘This is how the way it was in Cayman
Islands 25 years ago!'”

Ligon says the Cayman Islands might have even had more impressive
reefs than Bonaire’s back in the day. But coral throughout the US and
Caribbean has been in sharp decline for decades.

So how do Bonaire’s reefs remain intact?

Ramón de León is the manager of the Bonaire National Marine Park. He
says the island has an advantage in that it has no industries to pollute the
water.

The island is mostly undeveloped, which means relatively little farm and
lawn fertilizer run-off that can create marine algae blooms. And cool
upwellings in the region help balance the rising ocean temperatures. Warm
oceans can cause coral bleaching, which often kills the coral animal.

But de León says Bonaire really owes its healthy reefs to its history of
conservation laws. They date back to an era when such policies were rare.

“Bonaire start to protect sea turtles and turtle nests in 1961, back when
everybody was promoting sea turtle soups and nailing shells in the walls.”

By the end of the 1970s, Bonaire had banned spear fishing and made it
illegal to damage coral. For years, divers have been required to pay a
sizeable fee and take an orientation course before they’re allowed to dive
on the island. That helps them avoid touching the coral, which can kill it.

De León says the island still allows too much fishing. So several years ago,
he told the island’s fishermen they needed to choose a no-take zone to let
the reefs recover.

“I refuse to decide myself. I give the fishermen some prerequisites that they
have to have to close, and they chose which area. Is not my number-one
option, but is their number-one option. So I have to respect that.”

De León says because the fishermen chose the no-take zone, something
important happened. Compliance is high.

For all of Bonaire’s success in coral conservation, there are still some
problems. De León says its reefs suffer from leaky septic tanks and boat
pollution. And there are few of the large predator fish that used to maintain
population balance on the reefs.

But the island is a haven for researchers like Mark Patterson. He designs
underwater robots at Virginia Institute of Marine Sciences.

Last year he led a NOAA expedition to use robots to map Bonaire’s reefs.
He says the island’s reefs are valuable as a baseline by which other reefs
can be judged.

“If you’re an up-and-coming marine scientist and you go to a lot of the coral
reefs on the planet now, you might think that all coral reefs have always
look like this. And they haven’t! So the fact that we’ve got some pristine
reefs left is very important, and we’ve got to work very hard to protect them
because it shows us how the ecosystem should look and used to look
around the planet before things started to go downhill.”

Dumpster Divers Find Their Gold

  • One man's junk could be another man's organic groceries or building material. (Photo by Andrew Purtell)

A group of activists has found a way to live almost entirely off the stuff other people throw away. The Great Lakes Radio Consortium’s Amy Coombs finds one person’s trash is another’s ethical lifestyle:

Transcript

A group of activists has found a way to live almost entirely off the stuff other people throw away. The Great Lakes Radio Consortium’s Amy Coombs finds, one person’s trash is another’s ethical lifestyle:


(Sound of dumpster opening and rummaging)


“Cheesy bread, it’s kind of nice heated up… Some people love this crap.”


Jean C. has been dumpster diving for eight years and no longer considers it a chore.


“Dumpster diving can be a spiritual endeavor if you happen to believe it’s a sin to throw away food.”


C. is an activist. She’s also an accountant and is by no means homeless. She says she dumpster dives for food, clothing, office supplies, and building materials because she can’t bring herself to support wasteful manufacturers.


“The point of the dumpster diving lifestyle is to reclaim the waste of consumerist society.”


After dumpster diving in four major metropolitan areas, C. says you would be amazed by how much perfectly good stuff society throws away. If you do your homework, she says you can find almost anything you want.


“We’ve found organic cherries and chocolate and organic tofu, organic tofu burgers, chocolate soymilk, once we even found a whole case of white wine.”


Probably not too surprisingly, health officials say the lifestyle raises some sanitation concerns. Jerry LeMoine is a Food Inspector at the Santa Cruz County, California Health Department. He says even if dumpster-divers go for high-quality organic foods, taking food from a dumpster is risky.


“Potentially any type of bacteria could grow in a dumpster. Flies can get into dumpsters, rats, other types rodents, disease vectors, so it’s just unknown as to what the conditions are there and conditions might change at any moment in a dumpster.”


Dumpster divers say they’re aware of the risks, but Jean C. says she exercises great discretion. She says wading knee deep through other people’s trash is no worse than grocery shopping, as long as you know what to look for.


“We never eat unsanitary or dirty food. We only take meats if they’re frozen or vacuum sealed. Once we found a whole dumpster full of smoked salmon that was not going to go bad for years – and that was good. Everybody ate it.”


Lee Turner,a long-time dumpster diver, says people throw things away because Americans are wasteful. Turner has spent the past thirty years troubleshooting ways to build gadgets from others’ trash. He’s even built a back woods cabin entirely from salvaged materials.


(Sound of crickets)


“Welcome to my home… This is the kitchen, spice rack, this is the food cabinet, got running water, there’s a rain barrel, see…”


(Sound of water)


Turner built his shack illegally in a public forest, but he says he’s always been careful not to hurt the surrounding environment. He considers dumpster-diving to be part of a larger love for Nature.


Turner says using material that’s headed for the landfill makes a lot more sense than buying wood and encouraging the lumber and timber industry to cut down more trees.


“Most of the materials are found materials. Some of the wood came out of dumpsters.”


Turner and C. have turned dumpster-diving into an organized effort. They target the highest quality products, they stake out factory dumpsters to learn when mislabeled items are routinely tossed, and look for store employees willing to leak information about the next scheduled inventory reduction. It’s a conspiracy to salvage.


“What happens in a dumpster-diving collective is that you need to get a small group of quiet people, hopefully, and have them take a large amount of food back to a central location, where you’re going to wash it and process it and redistribute it, so that everyone gets what they need.”


It’s impossible to know how many students, activists, and old nature lovers scour garbage cans, but dumpster-diving is becoming an increasingly popular sport. And despite the social inhibitions and threat of food contamination, activists such as Turner and C. say they won’t abandon their search for edible, usable and fixable refuse any time soon.

Packrats Hooked on Freecycling

We all have things that we no longer use hidden in our closets, or stuffed away in the attic, or crammed into the garage. It’s not that we’ll ever use them, but we can’t bear to just throw them away. They’re still good. Now, a new service is matching up people who want to get rid of things with people who want those things. In part of an ongoing series called ‘Your Choice; Your Planet,’ the Great Lakes Radio Consortium’s Rebecca Williams explores freecycling:

We all have things that we no longer use hidden in our closets, or stuffed away
in the attic, or crammed into the garage. It’s not that we’ll ever use them, but we
can’t bear to just throw them away. They’re still good. Now, a new service is
matching up people who want to get rid of things with people who want those
things. In part of an ongoing series called ‘Your Choice; Your Planet,’ the Great
Lakes Radio Consortium’s Rebecca Williams explores freecycling:


I’m a packrat. I just wanted to make that clear right from the beginning. If you’re honest with yourself, you’ll probably confess you’re a packrat too.


But even I know when there’s something taking up space in my house that HAS to go. In the back of my closet, there’s a large, heavy, men’s wetsuit.


You know, a SCUBA diving suit. A relative gave it to me when he moved away. Now, I’m not a diver. I’m not even really a snorkeler. But I’ve kept it for two years. You know, just in case.


I need a little help getting rid of things. So, when I heard about freecycling… I thought, “This is it. This will help me face my inner packrat.”


Freecycling uses email groups to connect people in their hometowns. It brings together one person with their broken telescope… and that one person who needs – or just wants it.


The only rule – everything has to be free. No money, no trading. And also, you meet the giver or taker in person.


It’s Deron Beal’s idea. He manages recycling crews for businesses in Tuscon, Arizona. One day a year ago, he found himself with a warehouse full of stuff.


“We had a lot of the businesses we recycle with
downtown giving us old desks or computers, saying, can you do something with this. I’ll be darned if we got so much stuff in, I figured, let’s open this up to the public and set up the freecycle network.”


Beal emailed some friends and nonprofits. At first, he says it was just he and his friends giving each other stuff. But in just a few months, freecycle turned into a verb. Beal set up a website, freecycle-dot-org. And put instructions up so people could start freecycling in their own cities. Now, more than 90-thousand people all around the world are doing it.


So… I went to see the freecycling guy in my area, Aaron Liepman. He moderates two freecycle groups. He makes sure everything stays free, and steps in if people start arguing. He also helps packrats like me freecycle.


(sound in, typing)


Aaron sets me up on his computer.


“So, let me sign out and you sign in. (clicking) So now you type in your subject, just like an email message.


RW: “Offer: wetsuit. What else?”


“Wetsuit, SCUBA wetsuit. (crinkles, zipper noise) Looks like it’s a size large, that’ll be useful information. It has a little hat to keep you warm in the water (laughs).”


(typing out)


We look over my post, and I click Send.


So, I’ve started cleaning out my closet. But I’m not totally converted to this freecycling idea. I mean, really, aren’t we just moving our stuff from one house to the next? That doesn’t really cut down on consumption, does it?


I turned to University of Michigan professor Raymond DeYoung. He studies people’s buying and recycling habits. He thinks freecycling probably won’t change our buying habits all that much.


“Because we’re never going to be able with freecycling to get the new, get the novel, get the big, because by definition it’s already been bought, it’s already old, it’s the smaller. So it can’t impact our entire consumption behavior.”


DeYoung says, for freecycling to really succeed, we’d have to stop getting bigger houses. And stop filling them up with more and more things. But it’s hard, even for people who want to try to get by with less stuff.


I guess a wetsuit is a good first step.


It’s been a couple days, and I’ve gotten four messages. The first came five hours after my posting. From Shawn… he wrote: “I’ll take the wetsuit.” But he didn’t sound that excited.


In freecycling, you can use “first come, first serve” to decide who gets your item. But you don’t always have to. And I kind of wanted my wetsuit to be appreciated… you know, actually get to see the water. So I waited a couple days. Then, I got Kelly’s message. She wrote: “WOW!” in all capital letters and said her son would love the wetsuit… for snorkeling.


So I emailed Kelly. And we set up a place to meet in downtown Ann Arbor.


(street sound up)


“Wetsuit!” (Oh, are you Kelly?) “yeah, I’m Kelly.. (Hi, I’m Rebecca. This is the wetsuit.) Great!”


Kelly’s been freecycling for a month. And she says she’s hooked.


And judging from the postings, a lot of people are. They seem to like getting other people’s beer can collections and turtle sandboxes.


But some on the list worry it’s getting to be too much of a good thing. People have started to ask for laptops, and houses… and a time machine, any condition.


“I think because it’s so new, some people are asking for funny things, like don’t we all want cash, and a Lamborghini (laughs). I just laugh at those and go on.”


Kelly says she thinks the network will probably get past that after awhile, leaving behind just the really devoted freecyclers.

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:

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:


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.

Zebra Mussels Endanger Historic Shipwrecks

For years, biologists have warned that non-native “zebra mussels” threaten
plant and animal species throughout the Great Lakes. Now, underwater
archeologists say the mussels are also damaging historic shipwrecks. The Great
Lakes Radio Consortium’s Brian Mann visited an underwater museum on Lake Champlain and has our story:


It’s mid-afternoon and a haze floats over the dark green water, as dive-master Doug
Jones ties his boat to a yellow buoy. New York’s Adirondack mountains rise in the distance, but our destination this morning lies below the waves. Forty feet down on the silty bottom sits the wreck of a ship known as the Burlington Bay Horse Ferry…


“I suggest you do a tour around the wreck. It is possible to duck underneath part
of the decking that’s there. Please don’t, okay. It’s very fragile, especially the spokes to the paddlewheels that are sticking out. So buoyancy control is really important.”


The horse-powered ferry is one of six ships in Lake Champlain’s Underwater
Historic Preserve. Underwater sites like this one are sprinkled throughout
the Great Lakes. From commercial barges to warships, archeologists say
these wrecks hold a vital part of the region’s history.

Perched on the dive platform, I go through a final equipment check. I’m
sheathed from head to toe in a wet suit, insulation against the cold water.

“Now come on over here and hang onto the buoy.”


Here on the lake, each wreck has its own buoy and a network of guide ropes.
Before the ropes were installed, divers sometimes bumped against the ships’
fragile timbers. After a pause to get my bearings, I slip below the
surface.

Looking down, I see the buoy chain dwindle away into shadow. As I descend,
the water is cold and thick. Forty feet down, I reach the bottom. A dozen
strokes with my flippers and there it is, a man-made shape forming itself
out of shadows and watery dust.


I glide slowly past the delicate spokes of the paddle wheel. I drift above
the intricate, exposed ribbing of the deck.


“The horse ferry is the only known example of this type of vessel in North
America.”


Chris Sabick is Director of Conservation at the Lake Champlain Maritime
Museum, where they’ve built a half-scale model of the ship and its complex
gears.

Sabick: “It was a vessel type that was fairly widespread during the
19th century. But it’s one of those vessel types that has slipped
through the cracks of history and just kind of faded away.”


The lake’s murky water preserved the horse ferry. The fresh water is cold
and calm. The silt actually protects artifacts from bacteria. In many parts of
the Great Lakes, ships like this one have rested for centuries, completely
intact.


(Shells rattling)


But now that’s changing. A box of tiny, brown and white shells has been
added to the Maritime Museum’s display. It’s a new organism – the zebra mussel.
They arrived in the Great Lakes in the late 1980s, carried in the ballast
tanks of ships. Zebra mussels have wreaked havoc on native fish and plant
species. But they’ve also coated hundreds of historic wrecks:


Sabick: “The enormous weight of hundreds of thousands of these
shells on water-logged wood can obviously cause things to collapse.”


Using wrecks like the Horse Ferry, scientists throughout the Great Lakes are
studying ways that zebra mussels actually change the water’s protective
chemistry:


Sabick: “It seems that the microenvironment that exists deep inside the mussel
layer or colony attracts a type of bacteria that accelerates the
degradation of the iron. And obviously all of these shipwrecks are fastened
with iron fasteners.”


Over time, the wrecks could literally come apart at the seams.

Back in the water, I draw close to the horse ferry’s bow. Thick layers of
shells coat the ribbing. In places, not an inch of wood is visible.
Researchers say they won’t know for several years how much damage has been
done. But as the zebra mussels continue to spread, scientists fear that
underwater museums like this one could be lost forever.

Catching Underwater Looters

Laws protecting Great Lakes shipwrecks from looting vary from
state to state. But officials agree it’s nearly impossible to catch
underwater thieves… and only a handful of arrests are made each year.
Now, a Michigan case is encouraging officials to step up their efforts
to
save the shipwrecks. The Great Lakes Radio Consortium’s Wendy
Nelson reports:

Shipwrecks Hit the Web

Lake Superior is home to hundreds of shipwrecks. They’ve been preserved
there for well over a century. And they’re the destination of many
divers, hoping to explore their remains and learn their history.
Now, some of these sunken vessels can be explored without ever getting
wet. The Great Lakes Radio Consortium’s Todd Witter reports:
