A commission that advises the US and
Canadian governments on the Great Lakes wants to
see more accountability from Washington and
Ottawa. Chuck Quirmbach reports:
The International Joint Commission is focusing its latest report on
getting the US and Canada to set up an accountability plan for
restoring and protecting the Great Lakes.
US Commissioner Allen Olson says one example of accountability is
getting Congress to approve money for an Asian Carp barrier near
Chicago to keep the foreign fish out of the lakes.
“There are a number of members of the United States Congress of both
parties that are immediately accountable to address that issue.”
Canadian Commissioner Jack Blaney says the governments also have to be
accountable to what citizens said at recent IJC hearings:
“They want to swim at their beaches, they want to be able to eat the
fish. They want to be able to take water out of the lakes that they
don’t have to spend enormous sums treating.”
The IJC wants a preliminary plan to be ready by the summer of next
year.

US ports receive more than imported cargo.
They often receive fish and other aquatic organisms
from foreign ports. They stow away in the ballast
water of cargo ships. Once in US waters, some of
the foreign species become invaders, damaging the
ecosystem. The federal government has done little
to stop these invasive species. Rick Pluta reports now some states have decided to take
things into their own hands:
The damage caused by invasive species carried to the US in
ballast water is not only harmful to the environment, but it
hurts the economy. The federal regulations have not stopped the
problem. So, states such as California and Michigan have passed
laws that require foreign ships to treat ballast water like
pollution. They have to clean it up before they can discharge it
into a port. The problem is, almost no ships have a way to treat
the ballast.
In Michigan, the Great Lakes shipping industry is trying to delay
the new Michigan rules. Shipping companies, port owners, and
dock workers say Michigan’s new rules are jeopardizing jobs
without actually stopping the introduction of new species into
the Great Lakes.
The damage caused by invasive species carried to the US in
ballast water is not only harmful to the environment, but it
hurts the economy. The federal regulations have not stopped the
problem. So, states such as California and Michigan have passed
laws that require foreign ships to treat ballast water like
pollution. They have to clean it up before they can discharge it
into a port. The problem is, almost no ships have a way to treat
the ballast.
In Michigan, the Great Lakes shipping industry is trying to delay
the new Michigan rules. Shipping companies, port owners, and
dock workers say Michigan’s new rules are jeopardizing jobs
without actually stopping the introduction of new species into
the Great Lakes.
People in the shipping business say the problem is Michigan is
the only state in the Great Lakes region that is requiring ocean-
going freighters to install expensive technology as a condition
of using one of its ports.
John Jamian is the president of the Seaway Great Lakes Trade
Association. He says requiring ocean-going freighters to install
expensive technology before they can dock in Michigan ports won’t
solve the problem. The ships will just go to other Great Lakes
ports.
If a ship goes to Windsor or Toledo that doesn’t have these rules
and regulations, they will discharge their cargo. If there were
any critters on those ships they could still swim or crawl into
Michigan waters, so you still haven’t solved anything.
Jamian represents the owners of ships that travel from the
Atlantic Ocean to the Great Lakes via the Saint Lawrence Seaway.
He says ship owners will very likely avoid Michigan ports, and
choose to unload at ports in other states and Canada:
“The fact of the matter is that they’re not going to put an
expensive piece of equipment just because Michigan calls for it
on their ship when in fact it may not be acceptable anywhere else
in the world and it might just be easier to take that cargo
across the river and unload it where they don’t have these
regulations.”
And for Michigan ports that are near other competing ports,
that’s a concern. Patrick Sutka is the treasurer for Nicholson
Terminal and Dock Company at the Port of Detroit:
“We fear these ships may be going to other ports, such as Windsor
right across the waterway, or other competitors of ours such as
Toledo or Cleveland.”
At the height of the shipping season, there might be three
freighters at a time moored to the docks, offloading steel and
other cargo. A hundred trucks a day will move in and out of the
docking area to get those commodities to factories.
On the dock right now are dozens of stacks of 20-ton slabs of
steel from France and Russia. That Russian steel was most likely
shipped from a port in the Caspian Sea or the Black Sea. The
freighters take on ballast water from those seas for the voyage
to the Great Lakes. That ballast water helps keep the ships low
and steady in the water.
The ships are required to exchange the water in deep ocean mid-
journey. The salt water is supposed to kill the fresh water
organisms. But, some organisms can survive the trip. That’s how
zebra mussels, quagga mussels and the round goby fish made their
way from the Balkans to the Great Lakes.
Those invasive species and others combine to cost the economy an
estimated 5 billion dollars a year. For example, zebra
mussels cost taxpayers and utility customers. It shows up in
your power bill because the utilities have to pay divers to
scrape the crustaceans off pipes carrying cooling water to power
plants.
Shipping companies, port owners, and dock workers’ unions are all
pressuring Michigan to hold off on enforcing its new law. What
they’d really like is for the federal government to step in,
negotiate with Canada, and create a regional set of rules for
combating aquatic invaders:
“…But the federal government has not had the guts or the
gumption to step up to the plate and get this done.”
Patti Birkholz chairs the Michigan Senate Environmental Affairs
Committee. She sponsored the law:
“So we’re going to do it on a state-by-state basis. Our eco-
system within the Great Lakes is what many scientists have termed
‘on the tipping point.’ We cannot deal with any more invasive
species in this system, and we know the majority of the invasive
species come through the ocean-going vessels. They know they’re
the cause. We know they’re the cause. We’ve got to deal with this
situation.”
Michigan’s new law is as much a political statement as anything
else and other states are starting to follow Michigan’s lead.
Birkholz says Wisconsin and New York could pass ballast standards
this year.
In the mean time, Michigan environmental officials say they
intend to enforce the state’s requirements when the Great Lakes
shipping season resumes in the spring. But, so far, no ocean
freighters have applied for a permit to dock at a Michigan Port.

It’s the middle of winter and you’re craving some fresh,
juicy strawberries. Go to your local grocery store and
you’ll find lots of packaged strawberries shipped from the
west coast or down south. For locally grown strawberries,
you have to wait till June if you live in the Midwest. But
that’s starting to change. Jennifer Guerra has the story:
I like strawberries. A lot. There’s strawberry rhubarb pie
for starters, strawberry and spinach salad, strawberry
shortcake. But I’ve been on this kick lately of trying to
buy only locally-grown produce, which is admittedly hard to do when you
live in the Midwest, especially with strawberries. Most of
the year, they’re shipped in from Florida and California,
but there is one place in Michigan were you can still pick
strawberries as late as October.
(Guerra:) “The redder the better…that’s too green”
It’s snowing out. I’ve got on the winter coat, the hat, the gloves,
and I’m picking strawberries with Kelly Bowerman.
(Guerra:) “So, which one is this?”
(Bowerman:) “This is a tribute. We have aroma, diamante, and
tribute. Aroma is a nice big berry, diamante’s even a bigger berry,
but it just don’t turn red, it’s oranged-colored, and tribute is smaller with a lot more
flavor.”
(Guerra:) “Alright, let’s get all three. Let’s get a
variety.”
Bowerman calls his strawberries three finger berries, which
he says are roughly the same size as the ones shipped in
from California
(Bowerman and Guerra try strawberries)
And frankly, the strawberries better taste
good, seeing as how Bowerman spent 60,000 dollars on them.
Well, not on the actual berries themselves, but on the
hydroponics system he uses to grow the berries. With
hydroponics, he still grows his strawberries outside, but
instead of planting them in the ground, the runners sit in
pots above the ground in a solution of warm water and
minerals. And since there’s no soil, the strawberries can
grow from June to October without the roots freezing over at
the first sign of cold weather. Still, there’s only so much
a hydroponics system can do on its own:
“He’s gonna find out that people want strawberries at
Christmastime, and so the next step will be to put a
greenhouse over that system and then we have 12 months.”
Merle Jensen is a professor of plant science at the
University of Arizona and he knows his hydroponics. He
knows growers all across the country who’ve started moving
their hydroponics systems inside greenhouses so they can
artificially light the crops. That way, they can produce
year round. But wait, there’s more:
“All of our leafy vegetables – high value fruits like
strawberries – will all be under cover in the next 5 years.
I’m sure of that. It’s a rapid expansion, not only in the
United States, but we see it in Canada, Mexico. So, this is the wave
of the future.”
A future that Jensen swears will taste delicious:
“You know what? I can say that because we can control the
nutrition, the salinity within the root system such that we can
program that product to have more acid and more sugars and better
flavor, and we can do that through hydroponics at will. And local growing is
becoming bigger and bigger all the time. It’s just got an
image of being better.”
Of course in the Midwest, “local” is still pretty relative.
Our Michigan farmer, Kelly Bowerman, says he gets people
from up to 50 miles away to pick his strawberries:
“One guy bought $28 worth of strawberries, and he said that ain’t
no big deal cause it cost me $40 worth of gas to
get here and back.”
And he’ll have to continue putting in that kind of travel
time if he wants to eat locally grown strawberries in the
middle of winter. Unless of course Jensen’s right and
hydroponic greenhouse systems really are the wave of the
future. If so, it might not be too long before Bowerman’s
strawberries show up year round at your supermarket.
Oh, and by the way, I liked the tribute strawberries the
best. They were my favorite.

As Rebecca Williams reports, it’s the only invader in the Lakes that managers have been able to control… but it takes millions of taxpayers’ dollars every year to keep the blood-sucking parasite in check, and there’s no end in sight:
(Sounds of tank bubbling)
There’s a sea lamprey sucking on Marc Gaden’s hand.
“You can see he’s really got my thumb now, I’ll try and pull him off my thumb – this is a suction cup (popping sound of lamprey being detached).”
Gaden is with the Great Lakes Fishery Commission. It’s a group that was created by the US and Canadian governments with one main purpose: to control the sea lamprey. Gaden isn’t in any actual danger when a lamprey’s hanging on him. They don’t feed on warm-blooded creatures. But fish are another story.
“The mouth is ringed with sharp teeth, row after row of these sharp teeth, and in the middle of the mouth there is a tongue that flicks out and it’s sharp as a razor. What that tongue does is files its way through the side of the fish’s scales and skin and then the sea lamprey has access to blood and body fluids of the fish and that’s what it does, it feeds on them.”
Sea lamprey get fat drinking fish blood and fluids. They leave bloody holes in the side of fish, wounds that often kill the fish. Each lamprey can kill 40 pounds of fish a year.
Lamprey got into the lakes through manmade canals that connected to the Atlantic Ocean. By the 1940’s, the exotic species had invaded every one of the Great Lakes. Marc Gaden says by the 1950’s, lampreys had killed off most of the big predator fish in the Lakes.
“There’s literature around that time period that talked about gaping bloody wounds that commercial fishermen were finding on their catch, the commercial catch was beginning to go down the tubes, also because of overfishing, but sea lamprey was a major cause of that decline.”
Paul Jensen’s family used to fish for the popular lake trout before the lamprey wiped them out. Jensen now fishes for whitefish. He’s one of a small pool of commercial fishers who still pull a living from the Lakes.
“Every port along southern Michigan had commercial fishermen. South Haven, St. Joseph, Ludington, Manistee… There aren’t any, they’re gone. And one of the main reasons they’re gone, I think can be traced back to sea lamprey.”
Jensen says most commercial fishers these days have to do more than catch fish. He also runs a marina and builds research boats. Jensen says commercial fishers either had to adapt to the changes the lampreys brought or get out of the business.
“The whole food chain has just been devastated and turned upside down by exotics, and it’s been kind of a mystery; we have no clue as to where it’s gonna go. We’re glad with what we’re getting but I don’t know if we have much control of where it’s going.”
The people who manage fisheries have been wrestling for control over the sea lamprey. Marc Gaden says the lamprey control program has reduced the parasites’ numbers by 90 percent over the past 50 years. But he says lampreys have recently rebounded above target levels in several areas of the Great Lakes.
“It goes to show you these are crafty beasts. Even though they’re primitive and haven’t evolved much since the time of the dinosaurs, they still will find ways in which to spread and find new stream habitats and we always have to try our best to stay one step ahead of them.”
Gaden says the fishery commission has been aggressively treating the areas where lamprey numbers are too high. The main method is a lampricide that kills lamprey when they spawn in streams. Researchers are also working on chemical attractants to lure lampreys into traps.
But all of this takes money. Since the 1950’s, the US and Canada have spent about $300 million to keep lampreys in check. Marc Gaden says that sounds like a lot of money, until you look at the value of the fishery. It’s valued at about 4 billion dollars a year.
“So the amount of money we spend, upwards of 20 million a year, to keep lampreys under control, is a tiny fraction of the value of that fishery. But nevertheless it’s a cost we’re going to have to endure in perpetuity because the lampreys are not going away.”
But the Bush Administration’s proposed budget cut some of the funding for lamprey control. The fishery commission is hopeful that Congress will restore the funding. Marc Gaden says if we want any sport fishing, any tribal fishing, any commercial fishing… lampreys have to be kept under control, and that takes steady funding from Congress.
The sea lamprey invaded the Great Lakes more than a hundred years ago, and no one’s been able to get rid of it. But Rebecca Williams reports it’s the only invader in the Lakes that managers have been able to control. Experts say it can only be kept in check if Congress continues to provide funding each year:

The sea lamprey got into the Great Lakes through a manmade canal. The parasite attaches itself to fish and sucks out the blood and body fluids.
By the 1950’s, sea lampreys knocked out the big predator fish in the Lakes.
A few years later, biologists discovered a pesticide that kills lampreys. That pesticide is the major tool managers still use today to keep lamprey numbers down.
Marc Gaden is with the Great Lakes Fishery Commission. The commission’s in charge of controlling the lampreys. He says in order to have healthy fish populations, lampreys have to be kept in check.
“It’s like a coiled spring, as long as you have your thumb on it, everything’s fine but the moment you take it away it’ll just spring out of control, bounce back right to where it was before.”
The Bush Administration’s proposed budget cut some of the funding for the lamprey program. But the fishery commission is hopeful Congress will restore the funding.

Every artist depicts nature in a different way. In one artist’s world, nature is a place where people, animals and plant life are intertwined in vibrant color. Reporter Karen Kelly visited this new exhibit.
Six and seven year olds are pointing and chattering in front of a mural bursting with plant and animal life. One of them, Pierre Rousseau, describes his favorite parts of the painting.
“People, strawberries, some leaves, and fish, and kind of mister who has a bird on his head.”
The kids are at an exhibit of Norval Morrisseau’s work at the National Gallery of Art in Ottawa, Canada. Usually, you hear a lot of shushing when kids are in an art gallery.
Here, you can almost feel the energy between the kids and the paintings.
In one corner, Sadok Benmoussa and Amir Shallal are trying to figure out a mural that tells the story of creation.
“And what’s that big stuff? A flower? That big stuff… Oh, the big stuff, bears? A bear? A bear.”
Norval Morrisseau grew up on an Ojibway reservation on the north shore of Lake Superior, and that environment fills his paintings; the water, the animals, trees, berries.
But most important are the people, his own people interacting with that nature.
Gabe Vadas lived with Morrisseau for many years, and now that the artist has Parkinson’s disease, Vadas is his spokesman and guardian. He says when Morrisseau was growing up in the 50’s, his tribe began rejecting many of its traditions, and it’s connection to the natural world, so Morrisseau used his paintings to tell the stories he learned from his grandfather who was a shaman.
“And I think Norval just felt desperation as a young person to regain the identity that had been passed down to him. And of course Grandpa is only telling him, so there’s a desperation that ‘wait a minute, I’m the only one who’s learning these things and learning these legends.'”
One of these legends shows a man who changes into a thunderbird. It’s one of Morrisseau’s most famous works and it shows this transformation over six canvases. It begins with a man who has a bird perched on his head, as well as one in each arm. Slowly, his eyes get larger, his mouth forms a beak and his arms become wings. This is Morrisseau’s later style, and it resembles stained glass. He uses thick black lines to create an intricate design of colors and shapes.
Greg Hill curated the Morrisseau show for Canada’s national gallery. It’s now on display at the McMichael Gallery north of Toronto and it will be in New York City in January. Hill says the artist’s later works contain a message for everyone, not just members of his own community.
“He’s saying that we all exist here on mother earth and we need to respect that, those interrelationships.”
That message is something that visitor Yvette Debain says she could see in Morrisseau’s work.
“Very spiritual. That’s why it touches me because I believe also that we’re all part of a creation, and the spirit, you can say God, is in all the creation. It’s not separate.”
Morrisseau’s guardian, Gabe Vadas, says that when the artist returned to his hometown many years later, he was surprised to find many people who had gone back to the native traditions, and many told him that his paintings had inspired them to do so. Now, he hopes that with this major exhibit, more folks will be touched by his message.
John Pastor is trying to figure out how climate change will affect bogs and fens like this one. (Photo by Bob Kelleher)

Peat is key to holding carbon away from the atmosphere. Peat decomposes very slowly in the cold climate and cold water and stores more and more carbon. Should the water go away, and temperatures increase, peat could decompose much more quickly, releasing that stored carbon, and accelerating the pace of global change. (Photo by Bob Kelleher)
In northern Minnesota, a researcher says wetlands like bogs could be key to how fast the climate changes worldwide. And the areas like the upper United States and Canada in the bull’s eye for rapidly changing temperatures and rainfall. The GLRC’s Bob Kelleher reports:

In northern Minnesota, a researcher says wetlands like bogs could be key to how fast the
climate changes worldwide. And the areas like the upper United States and Canada in the
bull’s eye for rapidly changing temperatures and rainfall. The GLRC’s Bob Kelleher
has more:
What have wetlands, like fens and bogs, got to do with global warming? John Pastor says,
plenty.
Pastor is a professor and researcher with the Natural Resources Research Institute of the
University of Minnesota-Duluth. When Pastor straps on his hip waders, he goes where
almost no one else dares to go: into northern Minnesota’s fens, where water can be
several feet deep, and onto the bogs, where the mass of plant material is so thick it floats
on standing water.
A seven year-long study has revealed that fens and bogs can either help slow global
warming, or accelerate it. Pastor says all cards are off the table if temperatures keep
rising:
“The one problem in science that has the most ramifications throughout all of science – it’s
global warming.”
We’re in a swamp north of Duluth, Minnesota. Actually, it’s a fen, and it borders some
higher landscape nearby that’s a bog. What fens and bogs have in common is water and
peat, the not quite decomposed stuff left over when plants die. Pastor says peat lands are
one of the world’s significant bank accounts for carbon. They keep carbon out of the
atmosphere.
“Peat lands cover only 3% of the earth’s surface, but they contain 30% of all the carbon
that’s in all the soil in the world, locked in that partially decomposed organic matter, that
peat.”
Minnesota has vast peat lands that have been storing carbon for 10,000 years, but even
the size of Minnesota’s peat lands pales compared to those further north – around
Canada’s Hudson Bay, or in the Russian republics – all regions Pastor says that are facing
higher temperatures.
“All of the global climate models, one thing they all agree on, is that the greatest amount
of warming will occur in areas from Minnesota northward, and then inland – mid-
continent areas. So here we are. We’re sitting right now, right in the bullseye of the
greatest amount of warming that will happen on the face of the earth.”
This is the question: Will higher temperatures help trap more carbon in bogs, or force
more carbon into the atmosphere?
In this bog, Pastor’s been trying to figure out how warmer weather will affect bogs and
fens, and, in turn, what role the wetlands will play in global change. One thing he’s
found: the results depend largely on the water table, and that’s going to depend on
rainfall.
In some combinations, say with additional heat and additional rainfall, bogs could thrive,
trapping more carbon. That would be good. In other conditions, say with more heat but
less rainfall, bogs and fens could die and decompose, releasing even more carbon into the
atmosphere. That, Pastor says, would be bad:
“Now we have kind of a double whammy. Not only are we putting carbon dioxide from
fossil fuel into the atmosphere, the warning from that could cause the carbon from the
peat land also to go into the atmosphere and accelerate the warming.”
Predicting an outcome becomes mind numbing. Pastor’s working with new mathematical
theory to try to determine at what point global warming has gone too far.
“And so what seems to be happening is the temperatures of the earth have crossed some
kind of a threshold, where all the sudden, before that they crossed that threshold, the old
earth that we grew up with was stable. Now, it’s becoming very unstable, and ice sheets
are collapsing, birds and plants are migrating – everything’s happening very, very
quickly. And we’re going to enter into a new kind of earth that has a different kind of
stability – a different stable endpoint.”
Pastor says there’s no more complicated problem in all of science than global warming,
and no more important problem. Global warming, he says, changes everything, from the
forests to the wetlands. Pastor’s hoping the new mathematical models will provide more
definitive answers in time to do something about the outcome.

The American eel migrates from the salty Sargasso Sea into the fresh waters
of the eastern US and Canada. But their numbers have dropped significantly. Now, the
eel is getting help from dam operators. The GLRC’s Martha Foley
explains:
Fifty years ago, the American eel accounted for half the biomass in Lake
Ontario. Now it’s almost gone. Scientists don’t exactly know why, but some
researchers say dams are partially to blame.
Kevin McGrath is a scientist with the New York Power Authority. He’s been
looking for ways to help the migrating eels get past a dam in Massena, New York.
The dam is jointly operated by the US and Canada. McGrath helped design a
new eel passage that opened this summer. He says the new passage is working
well:
“The thing that is really amazing us is how quickly they’re going through
the system. They’re moving through the entire system in about an hour and a
half and we’re just incredibly pleased that it’s working as well as it is.”
McGrath says he wouldn’t be surprised if the new passage – and an older
one on the Canadian side – combine to pass 30,000 eels this season.
States are failing to stop the spread of an invasive insect that’s killing millions of ash trees. The GLRC’s Rebecca Williams reports:

States are failing to stop the spread of an invasive insect that’s killing
millions of ash trees. The GLRC’s Rebecca Williams reports:
People are spreading the emerald ash borer into new areas. The destructive
pest was first discovered killing ash trees in southeast Michigan four years ago.
Moving infested wood has spread the bug to Ontario, Ohio and Indiana. Now,
Illinois officials say the ash borer is infesting trees west of Chicago.
Researchers say moving infested firewood is the fastest way the beetle spreads.
Several states have banned moving firewood from quarantined areas. States
as far away as South Dakota are warning out-of-state campers to keep firewood at
home.
Critics argue states are too lenient in enforcing the bans.
State officials say they’re struggling to keep up, as federal funding to
stop the ash borer is cut.
Researchers warn the ash borer could wipe out billions of ash trees if it’s not stopped.
Hazardous waste is being trucked across the border from Mexico and Canada, but the U.S. government has no idea how much. The GLRC’s Lester Graham reports:

Hazardous waste is being trucked across the border from Mexico and Canada, but the US
government has no idea how much. The GLRC’s Lester Graham reports:
The U.S. Environmental Protection Agency used to try to keep track of how much toxic
waste was trucked across the borders, but three years ago abandoned its own program.
A report in the San Diego Union-Tribune found the work was turned over to a private
contractor, but it was behind the data by two years when that project folded in 2003. The
newspaper reports the EPA now relies on a much smaller program operated by a non-
profit organization. It’s compiling numbers from paper manifests the truckers turn in at
the border.
Definitions of hazardous waste differ in Mexico and Canada. And if companies try to
classify toxic material as less than hazardous, then they can pay less for disposal. The
EPA says it plans to standardize a hazardous waste manifest form later this year to better
determine what’s coming in and how much is coming in.
