Emotions Run High Over Dam Removal Questions

There are close to two hundred hydroelectric dams in Michigan, and almost half of those stopped making power a long time ago. Many of these dams are getting old and they need attention. The communities that own these dams are faced with a decision: pay to fix them, or pay to take them down. As Mark Brush reports it’s a decision that often stirs people’s emotions.

(Sound of Argo Dam)

The controversy around Argo Dam in Ann Arbor started when the State’s Dam Safety Program said there were problems were with the embankment next to the dam. The repair costs were estimated to be up to $300,000.

Laura Rubin is standing next to the dam on the Huron River. Rubin is the executive director of the Huron River Watershed Council, and she wants to take this dam out. She says taking the dam out would save the city money in the long run. She says it will also return the river to a more natural state, and would be better for fish and wildlife. Rubin says when she looks at the pond made by the dam, she doesn’t see good things.

“When I look at Argo Pond I see really a stinky, stagnant, non-oxygenated pond. It’s not really functioning. Other people look at it as, you know, this beautiful pond that they go down to. And it’s really, that’s just one of perspective, and sort of your background and your training.”

The people who like the dam accused Rubin and the Watershed Council of overhyping the problems with the dam, and with Argo Pond. The people most outspoken were the members of a local rowing club.

Rubin and others in favor of taking the dam out said the rowers could find better places to row on the Huron River, and the city could pay for the move.

Mike Taft is a coach for the Huron High School rowing team. He and many of the other rowers said the other places just wouldn’t work.

“You know my kids grew up here and this is where we spent our time. So, you can find what you want on various stretches of this river, and this is a one of a kind the way it is.”

Some environmentalists accused the rowers of digging their heels in – of not considering other options. Taft feels that accusation is unfair.

“I think this is not about the rowers. I think it’s about the Watershed Council pursuing their absolute aim here, which is to take out this dam.”

People with the Watershed Council say they do want the dam out, but they say they respect the rowers concerns.

The city of Ann Arbor put together a committee to help them with the decision. They held meetings and heard from some experts. They came to agreement on a lot of other issues about the river, but on the Argo Dam they just couldn’t agree.

Steve Yaffee is an expert on ways to manage environmental conflicts. He’s written extensively about the Spotted Owl case out west and he facilitated some of the Argo Dam meetings. He says in hindsight, he felt like the process could have been better informed. He thought it would have helped to have outside experts weigh in on the questions about science and about the alternatives for rowers.

“Because I think the rowing interests weren’t convinced that there were environmental benefits. And the environmentalists weren’t convinced that there weren’t options for the rowers. And if you’re not convinced of that, why work with that.”

Yaffee says for communities facing these big controversies it’s important for all the parties to first sit down and talk broadly about what they want for their community. He says it’s also important to have some creative thinkers at the table. People who can articulate a vision for the future and can come up with solutions.

For now, the city is planning to keep the dam. If it does, taxpayers will probably have to pay close to half a million dollars in repair and maintenance costs in the next several years, and for many cities with tight budgets money is often what ultimately drives their final decision of whether or not to keep a dam.

Rain Barrels and Rain Runoff

As cities cover more and more surface with pavement and buildings,
it’s taking a toll on the environment. Heavy rains flood off the
impervious surfaces and overload drains and creeks. Some cities are
trying new methods to control the problem. As Tracy Samilton
reports, Ann Arbor, Michigan is asking its residents to play a role by
catching their home’s rainwater in rain barrels:



Miller’s Creek in Ann Arbor is not a pretty creek. Part of it runs
alongside a congested four-lane road in one of the most developed
areas of the city. Since there’s almost no place left for rain to seep
slowly in the ground, it pours off the road and parking lots and
rooftops right into the creek:


“What you can see is all the roots that are exposed and very high
banks…”


Laura Rubin is head of the Huron River Watershed Council. Miller’s
Creek is part of the watershed. She says rain storms carry pollutants
and sediment into the creek, and sweep away animal and plant
species that might otherwise live here:


“This is not a healthy creek we call this impaired when they get flows
they’re so strong that they’re tearing away the banks.”


Rubin would like Miller’s Creek to be vibrant with life again one day.
But a lot of changes will have to happen first. She says nearby
businesses will have to build wetlands to retain their storm water.
The city will have to repave the roads to allow more drainage. And in
such a heavily populated area, residents will have to do something
too. Rubin says the first step is teaching people that a single point
source of pollution like a big factory is no longer the biggest threat to
water in their neighborhood:


“Now the main source of pollution is non-point pollution and that’s
us.”


Rubin says rain barrels could play a significant role in healing Miller’s
Creek. Rain barrels are just like they sound: big barrels that collect
water from a home’s rain gutters, to be dispersed later onto lawns or
gardens. One rain barrel can retain up to thirty percent of storm
water falling on a house. Under a dark grey sky that bodes rain,
Dave Aikins shows off his:


“It’s a big, uh, green trash can-like object…aesthetically, uh, I’m not
prepared to defend it.”


Aikins owns a medium-size house in downtown Ann Arbor. Now, with
a rain barrel installed on one side, he’ll catch half the rain that falls on
the house. He uses it to water his garden, but says someday he
might rig it so he can use the water for his laundry machine. A
neighbor kiddy-corner from him has installed one too, and they’ve
had neighborly arguments about proper installation and usage. He
likes how the rain barrel makes him feel.


“Living in an urban area, there’s no direct impact on you whether it
rains or not and this puts you back connected to natural environment,
so you start to care about whether you get your rain today.”

Aikins and other city residents have more than environmental
reasons to install rain barrels. The city water department is using a
carrot and stick approach to encourage their adoption. Installing a
rain barrel gets you a modest discount on the City of Ann Arbor’s new
storm water rates. Tom McMurtry is head of the new program:


“Under the old system, we charged one flat rate for every single
household whether you were an 800-square foot home in the city or a
5,000 square-foot mega-mansion.”


Now, the city will charge four different rates depending on the amount
of impervious pavement and size of the roof on the house. The
highest rate is three times more than the former flat rate, to better
reflect a big home’s impact on the city’s drains and creeks.
McMurtrie says about (blank) people have installed a rain barrel and
applied for the credit. He’d like to see at least 3,000 rain barrels
installed throughout the city. He doesn’t know how long it will take
to accomplish that:


“But every little bit helps.”


It’s an experiment in progress to see if having lots of rain barrels
around Miller’s Creek will help restore it. According to Laura Rubin
of the Huron River Watershed Council, it took about fifty years to
damage the creek this badly. It could take another fifty to bring it
back to health.

Lessons From Insect Infested Wood

Ash trees are dying by the millions because of an infestation of a

library. Lester Graham reports the wood beams and flooring will be a

Ash trees are dying by the millions because of an infestation of a
foreign bug. In one town, they’re using the dead wood to help build a
library. Lester Graham reports the wood beams and flooring will be a
permanent exhibit to remind visitors of the trees that were once there
and the cost of imported pests:


Craig Novotney is driving a team of black draft horses, some young
Percherons, through a wood lot. They’re dragging a pretty good sized
log out into the open to be trucked away and turned into lumber. They
could have used a bulldozer to do this job, but that would have damaged
a lot of the other trees in these woods:


“It’s a lot less impact on the forest floor. You don’t ruin near as
much stuff, you know, getting it out with horses. It’s a kind of
lighter approach to it.”


Sixty ash trees have been cut down on this four-acre piece of land.
They were all dead, killed by a bug called the emerald ash borer. The
wood from these dead trees will be used to make flooring, wood trim,
and to be support beams for a new branch library.


The architects knew they wanted to use ash, as a way of reminding
people of this disappearing natural resource. But it was the flooring
contractor who suggested the ash wood they needed was on the very
property where the library is to be built.


John Yarema owns Johnson Hardwood Floors:


“We were originally came out to look at flooring and ash. And when we
told them we could use the material off the site, they were excited.”


Rather than just flooring, Yarema suggested the architects use the dead
ash trees for some of the structure of the building, so that people
could see the damage the emerald ash borer had done, a sort of
permanent exhibit.


“One wall – it’s a 90 foot wall facing the woods – all glass. So, in
front of that, we’re going to have trees, emerald ash borer-killed
trees supporting that wall.”


The trees will still bear the marks of the damage done by the bug.
The ash tree is a popular tree, but like this place where they’re
chopping down the trees, city after city has had to cut down all of
their ash trees in an effort to stop the spread of the emerald ash
borer.


Despite efforts to quarantine infested areas, the emerald ash borer
is spreading. It was first detected in Michigan in 2002. It probably
came in shipping crates from China. The pest already has spread to a
half dozen other states and Ontario. The bug is being spread in part by people
hauling firewood with them on vacation and hunting trips, and in some
cases by nursery stock being shipped out of the area.


Josie Parker is the Director of the Library District in Ann Arbor,
Michigan where this new branch library is being built.


“Because it’s a public building, it will tell the story of what can
happen and did when there’s an infestation. This building will always
be here. The emerald ash borer tracings will be evident in the wood.
So, we’ll be able to explain (to) science classes and anyone who’s
interested what happened to ash trees and why we need to be more
careful about insect infestations.”


A lot of the dead ash has been cut up for firewood. But some people
have felt that the wood shouldn’t be wasted. It should be preserved
somehow. John Yarema says it makes him sad, seeing the ash tree
disappear. But, he likes the idea of using these ash trees in a way
that might serve as a lesson:


“It’s nice in the sense that it’s in an educational facility and not
chopped up into firewood. So, in that way, you feel better than
burning it in a fireplace. If we can make a statement and maybe
somebody will look at it, maybe a child will look at it and say, you
know, ‘Wow, this is…’ because (in) 40 years there aren’t going to be
any. The only ash trees that’ll be around will be in the flooring, the
walls, the ceiling and in the structure. I think we just all need to
open our eyes and hope for the best, I guess.”

There’s a lot of talk about the effects of global warming. But on a
recent frigid night, kids were thinking only of the cold and the thrill
of sledding down a hill. Producer Kyle Norris squeezed into the back of
a couple of sleds with the kids. She has this audio postcard
of the experience:


“My name is Kayli Mills and I’m twelve years old. Right now we’re
sledding and we’re actually snowboarding because last year we didn’t
really get to do much. It’s dark right now and it’s really fun to do it
in the dark not only is the hill clear, but um, and it’s quiet and
everything but it’s just really fun when you really can’t see much.”


“We’re getting on the sled and you want to sit how it’s most
comfortable to you because you don’t want to fall off, for sure,
especially with two people. Um, I’m sitting just on my butt but with my
legs hanging off. But I’m going to go on my knees in a second when we
take off, just doing this so that the sled doesn’t take off on its
own.”


(Sounds of sledding down the hill)


“Isn’t that fun? Go C.J.!”


“My name is C.J. and I’m nine years old. I smell snow and woods and
we’re at the bottom of Slauson Hill ’cause we just went down and it’s
really dark out and the clouds are white and the sky it blue. Well,
it’s creepy kind of cause, cause it’s a really steep hill.”


(Sounds of the sled thrown down on snow)


“We just sat down and we’ll probably go pretty fast but I don’t know.”


(Sounds of sledding)


“That was fun. That was really fun.”


(Kayli): “Definitely the wind in your hair is the best part….”


(C.J.): “It makes your cheek red when you go down like about five times
cause the wind blows into your cheeks really hard.”


(Kayli): “I’d say that if you look at the sky it’s very, very
beautiful I think even more than the day could even be. I mean, there’s
not really a sunset but you can kind of see the colors fading in from a
blue to a pink a yellow to a blue it’s almost like a rainbow but the
whole clouds are just a rainbow, dark skies. It’s very pretty right
now.”

The HIDDEN COSTS OF &Quot;JUNK" MAIL

If it seems like your mailbox is stuffed with more shiny credit card offers
and catalogs than ever before, you’re right. The U.S. Postal Service says
the volume of advertising mail outpaced first class mail for the first time
last year. The GLRC’s Rebecca Williams reports… city waste managers and
environmental groups are concerned that all that mail is going to add up to
a lot more waste:


(Sound of squeaky mailbox opening)


Maybe it’s just me, but it seems like no one sends me letters anymore.
Which means my mailbox is all coupons and catalogs and pizza ads. That’s
not all bad, but honestly, most of it goes right to the shredder.


(Sound of shredder)


According to the Environmental Protection Agency, that’s a pretty common
reaction. The EPA points to one study showing that 44 percent of advertising mail
is thrown away without being opened or read.


And there’s a lot coming in. Last year, marketers and non-profit groups sent
about 101 billion pieces of mail. That’s billion with a “B.”


You might call this junk mail, but people in the business have a more
affectionate name for it: direct mail.


Pat Kachura is with the Direct Marketing Association. She says direct mail
yields a very high return on investment.


“Marketers yield about a 7 dollar return on investment for every dollar
spent on catalog marketing, and about 15, almost 16 dollars return for every
dollar spent on non-catalog direct mail marketing.”


The Association’s annual report says those hefty returns are based on an
average of just 2.7 percent of people responding to the ads they get in the
mail. Last year, that meant more than 600 billion dollars in sales.


So, it’s profitable for marketers to fill up your mailbox.


But critics say there are hidden costs that marketers aren’t paying. Some
of those costs also arrive in your mailbox in the form of a bill from your
city for solid waste disposal or recycling.


(Sound of paper pouring into bunker from conveyor belt)


If your city accepts mixed paper for recycling, your junk mail comes to a
facility like this one where it’s sorted and packaged into giant bales
weighing one ton each.


Bryan Weinert is the solid waste coordinator for the city of Ann Arbor,
Michigan.


“We end up getting about $70 a ton back in the value of the junk mail that’s
recycled. But remember it’s costing the city roughly $125 a ton or so to
pick it up.”


Weinert says his city is lucky because it has double the nation’s average
recycling rate. He says communities that don’t have a recycling program
bear even higher costs to dispose of mixed paper.


In this case, the bales of paper get made into Kellogg’s cereal boxes.


Tom Watson is with the National Waste Prevention Coalition. He says it’s
good when there’s a local market for recycled junk mail, but much of it
actually gets sent overseas.


“The unwanted mail, the mixed paper, generally has a very low value, that is often
shipped to China and it comes back to us in the kind of mottled packaging found on
the products that we buy from China. So, it comes full circle but it’s not
very efficient, all the costs of the transportation and recycling.”


Watson says it’d be much more efficient to cut back on all that mail in the
first place.


The Direct Marketing Association does offer an opt-out service. The group
says their members aren’t allowed to send any new mailings to people who
sign up. The fastest way to sign up is online, but you have to pay a $5
charge.


Tom Watson with the National Waste Prevention Coalition says that charge
might put people off. He says he’d like to see a national Do Not Mail list.
One that isn’t controlled by the industry.


“It’s very common in other countries, you can’t send mail to someone unless
they say in advance, yes I want to receive that mail from you.”


You might expect that the folks at the Direct Marketing Association aren’t
fans of the Do Not Mail list idea, but they’re not the only ones.


“What is our position on that? (laughs) I wouldn’t like that to occur.”


George Hurst is the brand manager of direct mail for the Postal Service.
It’s his job to get direct mailers to send more mail. That’s because it’s
the second largest source of revenue for the Postal Service, in the tens of
billions of dollars.


Hurst says new laws aren’t needed. Instead, he says marketers just need to
know their audiences.


“The ones that don’t do it too well, and just blanket the earth with a message,
God bless ’em, we love the postage. But you gotta know that if you’re
talking to someone who is say, 100 miles away, about coming to your
dry cleaners, you’re probably missing the mark.”


But critics say consumers deserve to have more say over the mail they bring
into their homes. They say marketers make so much money from the mail they
send… that for that small chance you might be interested in a coupon book or
sale notice, you shouldn’t have to pay the cost to throw it away or recycle
it.

States Struggle to Control Ash Borer

  • The emerald ash borer is killing ash trees in Michigan, Ohio, Indiana and Ontario... and scientists say all the ash in North America is at risk if the beetle can't be stopped. (Photo courtesy of USFS)

found a way to stop it in its tracks. The GLRC’s Rebecca Williams reports cities and states are struggling to find money to keep the beetle from spreading:

Transcript

A tiny green beetle is killing millions of ash trees. And so far nobody’s
found a way to stop it in its tracks. The GLRC’s Rebecca Williams
reports cities and states are struggling to find money to keep the beetle
from spreading:


Once emerald ash borers chew their way into your ash trees, there’s
pretty much only one thing you can do.


(Sound of chainsaw and tree cracking and falling)


Crews here have been sawing down and chipping up trees six days a
week. In some places, crews are cutting down both dead and live trees.
Dead trees are a safety hazard. Cutting live trees near infested areas can
help contain the beetles.


The emerald ash borer is native to China. Scientists think it got in on
wood packing crates more than ten years ago. The emerald ash borer eats
through the living part of the tree just underneath the bark. The beetles
cut off the tree’s water and food supply… so it starves to death. 15
million ash trees are dead or dying in Michigan. Hundreds of thousands
are dying in Ohio, Indiana and Ontario, and it could spread to other states
soon.


Some cities have been hit really hard. For example, some of the trees in
Ann Arbor, Michigan have been dead for a couple of years. Kay
Sichenader is the city’s forester. She says she’s worried about limbs
breaking off trees, or bark falling off in 80 pound chunks.


“There’s some terrifically bad ones out there. Nothing will make me
happier than when those trees are down, I gotta tell you.”


This isn’t the first time cities have lost big shade trees. Dutch elm
disease almost wiped out American elms in the 1960’s and 70’s. It’s a
little ironic: people planted ash trees to replace the elms because they
thought ash trees were invincible.


That love of ash trees means cities are losing 20 or 30 percent of their
trees, and they’re spending millions of dollars to take trees out.


Forester Kay Sichenader says her city normally takes out a thousand old
trees a year. Now, she’s got ten times as many trees to cut down.


“If I never bumped it up, and we just remained with our thousand a year,
we would never change because it would take me ten years to get the ash
out. In the meantime I’d have 10,000 more dead trees to deal with. It’s
sobering.”


Sichenader says the city’s trying to get the dead ash trees out as fast as
they can. She’s contracted five extra crews to saw down trees. She
hopes they’ll be done by the end of the year, but it might be longer.


Many homeowners are getting impatient. They’re worried about big
branches falling on their cars or homes. Or worse, falling on their kids.


Laura Lee Hayes lives in a cul-de-sac with four infested ash trees. She
points out a big branch on her neighbor’s dead tree.


“This whole piece is just laying here, ready to pull off, and there are
small children that play in this yard. That’s why I look to my city to get
over here and get these trees down. There’s a real frightening aspect to
that.”


Hayes says she tried to pay to take the trees down herself, but she found
out it would’ve cost more than a thousand dollars.


In Indiana, homeowners now have to spend their own money to get rid of
dead trees in their yards. State officials say they can’t afford to keep
cutting down live ash trees to slow the infestation. The state won’t be
giving money to help cities cut down dead trees either. That could mean
the emerald ash borer will spread unchecked.


At first, the federal government sent states several million dollars to fight
the beetle, but now the money’s just trickling in. In 2004, Michigan
Governor Jennifer Granholm asked President Bush to declare the state a
federal disaster area. That request was denied. Recently, officials in
Ohio and Michigan said they’ll have to cut back on containing new
infestations.


These trends worry scientists.


Deb McCullough is a forest entomologist at Michigan State University.
She says states barely have enough money to monitor how far the beetle’s
spreading, and she says a lot more money’s needed for ad campaigns to
tell people to stop moving firewood. The beetle spreads fastest when
campers or hunters move infested wood.


“You have to look down the road, and either you spend millions of
dollars today to try to contain emerald ash borer or we’re going to be
looking at losses in the tens of billions of dollars in the future, and it’s not
too distant of a future.”


McCullough says if more funding doesn’t come in states might need to
have timber sales to take ash out before the beetle kills it. And cities will
still be paying millions of dollars to take out dead trees. That means
people who live in those cities might see cuts in other programs or have
to pay higher taxes.


Deb McCullough says the economic impacts are serious… but the
environmental impacts could be even worse. She says it’s hard to know
how wildlife might be affected if we continue to lose millions of ash
trees.

Ten Threats: Southwest After Great Lakes Water?

  • This billboard was displayed along several major highways in Michigan. The sponsors were hoping to raise awareness about water diversion, but do these arid states really pose a threat to the Great Lakes? (Photo courtesy of Central Michigan Life )

Transcript

We’re continuing our series on the Great Lakes. One of the Ten Threats
to the Great Lakes that experts identified was water withdrawals. Our
guide in this series, Lester Graham, says the next report looks at one of
the myths of water withdrawals.

Environmentalists and policy makers say a thirsty world could pose a
major threat to the Great Lakes. Water wars have been predicted in arid
parts of the globe, and some say the laws of supply and demand might
one-day lead to a raid on the region’s fresh water. Reporter Mark Brush takes a
closer look at one claim: that states in the southwest will one day come
after the Great Lakes water… and finds that it might just be H2O hype…


Taking water out of the Great Lakes is a hot button issue, and no one is
more aware of this than politicians looking for votes. In the 2004
campaign, President Bush used the issue to rally a crowd in Traverse
City, Michigan:


“My position is clear. We are never going to allow the diversion of
Great Lakes water.”


(Sound of applause)


The issue taps into people’s emotions. People get outraged when they think
of someone taking water out of the Lakes – especially when they’ve seen lake
levels dropping over the years, and the region’s political leaders have listened
to those concerns. The states and provinces that surround the world’s largest fresh
water system are working on a compact that will prevent water diversions.


But where is the threat to Great Lakes water coming from? We
conducted an informal poll on the streets of Ann Arbor, and we asked
people: “who wants water from the Great Lakes?” Six out of the ten
people we talked to pointed to the west:


(Sound of street)


“Las Vegas, the Southwest.”


“Probably the dry states in the West. Arizona, Nevada.”


“I think the west should keep their damn hands off our water.”


But do the arid states in the West really pose a threat to Great Lakes
water? It turns out – this same question was asked more than twenty
years ago.


In the 1980s, the U.S. Army Corps of Engineers studied the possibility of
moving Lake Superior water to the Missouri River. It’s a distance of
about six hundred miles. Farmers in the High Plains states were hoping
to use this water to irrigate their crops.


Jonathan Bulkley is a professor of civil and environmental engineering at
the University of Michigan. Bulkley and his colleagues analyzed this
diversion plan, and he says the whole project would have been too
expensive:


“We found it would take seven 1000 megawatt power plants dedicated to
lifting the water, because water needs to be lifted to reach these distant
locations, and in addition there would have to be conveyance structures
built to transport the water, and our conclusion was the total cost would
far exceed the value of the water.”


In other words, Bulkley found that it would be cheaper for these states to
find other sources of water – or to find ways to conserve the water they
had left, and this was a diversion of only 600 miles. A diversion all the
way to the Southwest would mean piping the water almost twice that
distance.


“We are always looking for extra water – everyone in the Southwest is
looking for extra water.”


Bob Barrett is a spokesperson for the Central Arizona Project. It’s one of
the biggest water suppliers in the Southwest. The Project pulls water
from the Colorado River and delivers it to southern Arizona. Barrett
says he can’t imagine a situation where Great Lakes water is pumped for
more than a thousand miles to the Colorado River:


“Most people don’t realize it, but a gallon of water weighs about eight
pounds, and if you’re going to push that up and over the Rocky
Mountains you’re going to need a lot of power. (Laughs) So, it’s a good
idea, but I don’t see how anybody could pay for it.”


But some observers say even though it might not happen today – it could
happen in the future. They point to a fast-growing population and a fast-
dwindling fresh water supply in the southwest. They say that
combination could drive engineers and policy makers to devise a way to
get Great Lakes water.


But Barrett says for states like Arizona, California, and even Texas – it
would be cheaper for them to build desalinization plants… these plants
convert ocean water into drinking water:


“I mean why should Texas build for a canal and then have to maintain it
from the Great Lakes down to the state of Texas when they can go to the
Gulf Coast and build several desalinization plants, and then just pipe it
wherever they need it?”


So, a large-scale water diversion to the southwest seems unlikely.
Experts say water from the Great Lakes is much more likely to go to
cities and towns right on the edge of the basin, but as legislators move to
tighten restrictions on diversions – even these places will
have a hard time getting access to the water.

There’s no disputing that fish is healthful food, but too much of certain
kinds of fish can be dangerous, especially if you’re a woman planning to
have children. That’s because some fish contain elevated levels of

Transcript

We’re continuing our series ‘Ten Threats to the Great Lakes.’ One of the
threats identified by experts was air pollution that in turn pollutes the
lakes. The Great Lakes Radio Consortium’s Lester Graham is our guide
in this series. He says the next report looks at one pollutant that
eventually affects people.


There’s no disputing that fish is healthful food, but too much of certain
kinds of fish can be dangerous, especially if you’re a woman planning to
have children. That’s because some fish contain elevated levels of
mercury. Mercury is a toxic contaminant that can cause neurological
damage. Julie Halpert filed this report about the harms mercury can
cause:


Three years ago, when she was 18, Ayla Brown was healthy, but
suddenly, she started getting sick all the time. She was always tired, she
became anemic and had sore throats. Her tonsils had deteriorated so
much that they had to be removed. Her doctor couldn’t figure out why,
so he decided to test her for heavy metals poisoning.


The result? Ayla’s mercury levels were off the charts. They were five
times higher than the normal level. Her entire family was tested and
their levels also were above normal.


“The only conclusion we could come to is that in the past year or so since
we had moved to Ann Arbor, we had started eating a lot of fish and a lot
of fish that we now know is very known to be high in mercury, such as
swordfish and tuna and stuff like that.”


The Browns ate several meals of fish every week. Some of it was
ocean fish. Some of it was Great Lakes fish. After the diagnosis, they
cut fish out of their diet altogether. Within a year, the mercury levels
returned to normal.


“You are trying so hard to eat healthy and my family always was very
health conscious and so it’s so frustrating when you’ve done something
that you thought was good for you and realize that it was completely the
wrong thing.”


Fish are generally considered part of a healthy diet, but not all fish are
entirely safe. That’s because of mercury. Mercury exists naturally in the
environment at low levels, but higher amounts are getting into the food
chain.


Coal-burning power plants emit mercury, which eventually settles into
the Great Lakes. Then, aquatic microorganisms convert the substance
into methyl mercury, which is more toxic.


Those microorganisms form the base of the food chain. Small fish eat
microorganisms. Then, larger fish eat the smaller ones. As that happens,
the mercury concentrations escalate, making big large mouth fish like
trout, salmon and some walleye especially contaminated.


When people eat the fish, the mercury is passed on to them. Women of
childbearing age and their fetuses are most at risk.


Michael Carvan is with the University of Wisconsin-Milwaukee’s Great
Lakes Water Institute. He says the exposure isn’t just from the fish that
women eat while they’re pregnant. A woman can pass her entire lifetime
load of mercury to her baby. He says that 15% of all women of
childbearing age have high enough levels so that their fetuses will
contain mercury of one part per million or higher.


“Even at really low levels, around one part per million, you’re talking
about some subtle coordination difficulties, you’re talking about
problems with memory and problems with neuro-processing and IQ
deficits.”


Because of these concerns, the Environmental Protection Agency and
the Food and Drug Administration issued an advisory for women of
childbearing age and children, suggesting they eat fish and shellfish only
twice a week.


But one expert is concerned by all this talk about how mercury harms
people. John Dellinger was on a task force, which provided guidance on
fish consumption advisories. Dellinger studied people who lived on
Lake Superior who he thought would eat a lot of fish, but he found
something else.


“We basically discovered that from an epidemiologic point of view, these
populations have other things that are adversely affecting their health,
that in fact will probably overshadow anything we’re going to see from
the contaminants in their fish.”


Dellinger said the people were so concerned about contaminants in
fish, that they started relying on store-bought, processed food instead.
Those foods were higher in fat and sugar and contained other, less
healthful, ingredients. So, obesity and diabetes caused health problems,
not mercury poisoning, and Dellinger says that ended up being a worse
situation.


He says the key is to choose wisely, avoiding fish such as swordfish,
tuna steaks and the larger predator Great Lakes fish that are high in
mercury. That’s the only measure you can take right now, but that doesn’t
solve the problem. The real challenge will be to get rid of the mercury
that ends up contaminating the fish.

Tree Farmer Makes Season Merrier

It’s that time of year again – parking lots across the country are filled with Christmas trees. Just about one out of every three people who celebrate Christmas buys a live tree. The Great Lakes Radio Consortium’s Mark Brush spent some time with one tree grower in the height of tree-selling season:


(Sound of generator, saws, people chatting)


It’s a crisp afternoon at this Christmas tree lot. That generator you hear is powering the electric saws. The guys trim up the base of the tree so it’ll fit on a tree stand. Their hands are all blackened with sap and dirt from wrestling hundreds of trees off of the flat bed truck. They take the bundled trees, open them up, and stick them onto stands. They’ve created a makeshift forest in the middle of this strip mall parking lot. Customers wander through the forest searching for the perfect tree.


(sound of talking)


Duke Wagatha runs this tree lot in southeastern Michigan. He appears with his trees each year from his farm up north.


“We get here the weekend before Thanksgiving. Takes us probably about a week, or five days to set up. With the idea of opening the day after Thanksgiving. We like to let folks get one holiday out of the way and then we start on the next…”


He calls his business “Flat-Snoots Trees.” You couldn’t tell from looking at his face now, but he calls it “Flat-Snoots” to make light of a broken nose he suffered in high school.


Duke’s coveralls are all tarnished with pine needles and sap. And when he moves, you hear ringing from the bells on his hat. He moves between the trees in his parking lot forest telling his customers jokes and filling their heads with visions of Scotch Pine, Fraser Firs, and Blue Spruce.


Margaret Jahnke has been buying trees from Duke for more than six years.


“He just makes it really personable – and there was one year, it was really kind of warm and he had his Hawaiian shirt on and his straw hat, and he was out here partyin’ away! And I’m like, ‘Whoa!’ It’s fun to come… you know just to run in… you know to talk to him. And they’re really helpful!”


While they’re away from home, Duke and his crew live in a 1950’s vintage trailer. The trailer’s paint is faded, but Duke spruces it up for the holidays with wreaths and pine boughs. And when you step inside, the old lamps and rustic furniture make it seem as if you’ve stepped back in time.


(Sound of trailer door opening)


“Whooo! It feels better in here doesn’t it? I needed a good excuse to get in here.”


The trailer also doubles as his office. Customers pay for their trees in here, and on occasion, they’ll have a complimentary nip of what Duke calls his “bad Schnapps.” Duke is from Mesick, a small rural town in northern Michigan. Christmas tree farming is big business in Michigan. The state is second only to Oregon in the number of acres that are in Christmas tree production.


Duke calls himself a small-time grower. He’s a carpenter by trade, but his work tends to dry up in the long winter months.


“It’s not enough to make a living for me and my family year-round, but it’s a good extra source of income… and, uh… winters are tough up there, so if you make a little bit of extra money – winters are tough and expensive. Living in the country, you know, like anybody, you got propane bills and all that, and it’s a little colder up there, so to make a little bit of money going into winter is pretty nice.”


A lot of work went into growing the trees that are now on his lot. Each summer, workers plod through the rows and rows of trees, swinging razor sharp machetes. They trim each tree to give them that classic, symmetrical, Christmas tree shape. And after about ten years, the trees are ready for harvest. They’re cut, they’re run through a baling machine, and they’re loaded onto trucks and shipped down to the lots.


(sound of customers on lot)


Even though there’s a jovial atmosphere on the lot, there’s also a sense of urgency. After all, Duke only has a few weeks to sell trees that in many cases have taken more than ten years to grow. And while selling the trees is an important part of Duke’s income, he gets something else out of it. He enjoys making connections with the people who wander through his tree lot.


“Sometimes you get grumpy folks coming in, and it’s usually just because they’re overwhelmed with shopping… it’s cold out… they didn’t wear their long underwear or whatever… but we can usually get them turned around, you know, we have a little fun with them… like I say if we have to bring them to the trailer and have a shot of bad Schnapps with ’em, hey, that’s just fine too.”


It’s closing time at the tree lot. The workers are headed for a warmer space. Right now, Duke’s trailer is filled with his extended family and friends…


(sound of door opening)


“Come on in! This is Duke’s family… it’s warm in here, huh?”


Duke will continue to sell his trees right up until Christmas Eve. Then, he’ll drive home to spend a few days with his family before he comes back to tear the lot down.


“It’s kind of like the circus coming to town. You build up your tree lot, you almost build like, well, I wouldn’t say a village, but a little spot where there was nothing, just, you know, an asphalt parking lot. And when we leave, there’s nothing left – we sweep ‘er up and go – so it’s almost like a mirage… were those guys really here?”


(sound of laughter)


And so, they spring to their trucks and drive out of sight, knowing they’ve helped make the season merry night after night.

True Costs of the Emerald Ash Borer

Officials in Michigan, Ohio, and Ontario are all gearing up for another
summer of fighting the emerald ash borer. The Asian insect burrows
into and
kills ash trees. The economic and the environmental costs of the
invasive
beetle are adding up. The Great Lakes Radio Consortium’s Bill
Poorman
reports:


Researchers first identified the emerald ash borer just a couple of years
ago. The small, metallic-green beetle has killed millions of ash trees,
especially in southeast Michigan where thirteen counties are under
quarantine. Paul Bairley is the city forester for Ann Arbor, Michigan.
The
city is spending millions of dollars fighting the emerald ash borer. But
Bairley says, losing the trees has a significant environmental cost, as
well. Larger ash trees can provide enough oxygen for a family of four
for a
year, and other benefits.


“That same tree will provide the cooling value of about twenty
room-size air conditioners, BTU equivalents…and probably most importantly, air filtration
of pollutants. A car driven 11-thousand miles per year, that tree could
absorb effectively, recycle the exhaust from that automobile.”


Researchers think the emerald ash borer first arrived in the mid 90s
aboard
packing materials for goods shipped from Asian countries. For the
Great
Lakes Radio Consortium, I’m Bill Poorman.
