Some of the world’s most intricate
architecture is not always constructed by
humans. Sometimes the most skilled architectural
wonders are designed by nature. Gretchen Cuda reports on an exhibit that celebrates
birds’ nests:

Judith McMillan didn’t find her inspiration in tree branches. She found it in the
basement of the museum where she works. She was rummaging through drawers
there when she came across a hundred-year-old collection of bird nests.

“This Museum must have 10 cabinets full of bird’s nests.”

She was fascinated and immediately knew she had a new subject for her art.

McMillan is a photographer who has been volunteering at the Cleveland Museum of
Natural history for 20 years. In her latest exhibit, titled “Nesting”, she captures some
of natures most inspiring, and often overlooked architecture – the nests of birds.

(sound of exhibit crowd)

“I was looking for nests that were different from each other so that you could see that
these birds were little architects. And there were so many different kinds of materials
used – and then the eggs could be so different. Some with little tiny speckles, some
with different colors some with little calligraphic streaks around them, so it was that
variety that I wanted to capture.”

All the photographs are in black and white – because she really wanted people to
concentrate on the architecture without being seduced by the color. She’s fascinated
by the way different birds chose very specific materials to work with – everything
from marsh reeds, grape vine, or little knotty twigs – like this one.

“This is a vermillion flycatcher – it’s almost like it’s made of pick up sticks in the way
their pushed together.”

And to emphasize the diversity of structures birds can create she shows me an
Orioles nest that’s five inches deep and formerly hung like a basket from a tree.

“I actually had to shine a flashlight down in it when I was taking the photograph in
order to get the eggs to show up.”

Most of the nests and eggs were collected around the turn of the 20th century by
amateur naturalists who never thought twice about disturbing the natural wildlife.

But the practice eventually fell out of fashion as people became more
environmentally conscious and large nest and egg collections were often turned over
to museums – explains Andy Jones the museum’s ornithologist.

“People whose grandfathers were dealing with eggs as a hobby, well their
grandfathers are passing away and so they contact their local university or natural
history museum, and say, ‘hey do you want these?’”

Those specimens were originally collected just because they were pretty. These
days, they’re still beautiful, but they also serve a scientific purpose. Scientists can
look at things such as the thickness of the shells, or the type and number of birds
found in a specific location and tell a lot about the birds. They can see where birds
used to live and how far their territories reached. They can even tell if a bird that’s
extinct now once lived in an area.

Judith McMillan hopes her photographs will not only show how beautiful the birds’
handiwork was, but will also inspire people to do something about saving the birds
that are still here.

“I didn’t understand until I started using a camera myself how you can isolate
something and make people look at it differently–And I hope through my
photographs I’m getting people to take a fresh look at things. It’s hard to have an
appreciation of nature unless you really look at it and start to really care about it.”

Recent surveys have found that many songbirds are disappearing. If people don’t
start caring, those photographs and drawers full of nests might become the only
reminders of many more species that go extinct.

Protesters Target Pvc

  • Activists want Target to stop carrying PVC plastic products because of potential links with toxins. (photo by Lester Graham)

Polyvinyl chloride and the chemicals used to make it are thought to be
linked to birth defects and cancers. So activists are urging companies
to stop using the plastic. America’s 6th largest retailer Target was
recently handed 10,000 signatures at its annual shareholders
meeting. The petition urges the company to phase out the use of PVC
plastic in the products it sells. Lisa Ann Pinkerton reports:

Polyvinyl chloride and the chemicals used
to make it are thought by some to be linked to
birth defects and cancers. The petition was
delivered to the annual shareholders meeting.
Lisa Ann Pinkerton has more:


In white hazmat suits and dust masks, about 30 protesters chant on the street in front of the new Target store.
It’s the site of this year’s shareholder meeting
and one of those protesters is Brad Melzer, a biology professor at Lake Erie
College in Ohio. But Melzer’s not shaking a protest sign right now. Instead, he’s trying to keep his infant
son shaded and cool in the noon-day sun. As little Winston lounges in a stroller, sucking on a bottle, Melzer says he’s
here today because he’s read about PVC plastic and its possible toxicity to
children:


“To be honest, I don’t even know if this nipple has PVC in it. He could already be
ingesting these things.”


Protests like this one are happening simultaneously in 200 locations across the country,
but in Cleveland, protesters have turned in a petition with 10,000 signatures urging Target
to stop stocking its shelvesproducts containing polyvinyl chloride, or PVC.


Not too far away from the Melzers, is Doctor Cynthia Bearer of Rainbow Babies and Children’s Hospital, and she chats with a
woman holding a protest sign reading “Way off Target with Toxic Toys.”


Bearer’s main concern is chemicals called pthalates, which help soften PVC plastic. The
most common is known as DEHP. Bearer says the chemicals may leach from teething
rings, shower curtains and packaging, and put young children at risk:


“Pthalates are known to be endocrine disrupters. They interact with the thyroid
hormone.”


And they can cause abnormalities in infants, she says, including reproductive
difficulties:


“So we can actually measure health effects, particularly on male infants in terms of their
sexual development at the time of birth from exposure to pthalates.”


Like Dr. Bearer and Brad Melzer, some of the protesters are science professionals.
Some are just concerned parents and others are advocates for children. Maureen Swanson is with the Learning Disabilities Association of America. She says the development of children’s brains might be impaired by exposure
to chemicals in PVC. She says even if science can’t pinpoint right now why 1 in 6
children suffer from learning disabilities, something needs to be done. She says the burden on America’s schools is growing:


“The percentage of school funding that has to go to help these kids who have learning
and developmental disabilities, then that impacts the school’s ability to fund other
educational needs.”


Some precautions have been made to reduce exposure to some of the PVC-related chemicals.
The US Food and Drug Administration has advised against using DEHP in medical
devices, and the Environmental Protection Agency has listed it as a probable carcinogen,
but the government doesn’t bar the use of DEHP in any product.


Even without the ban on the chemicals, 53 companies, including Target’s largest competitor, Wal-Mart, have begun phasing
out the products that contain PVC. Target Spokeswoman Carolyn Brookter says her company has some options it’s working on,
but it’s reluctant to set a time table for phasing out PVC. But she says that doesn’t mean that Target isn’t taking the
issue seriously:


“We’re talking to out buyers, we’re talking to our venders and we’re asking them to look
into some alternatives that we have.”


If Target doesn’t move on the PVC issue, new dad Brian Melzer
says he’ll be left with a difficult shopping dilemma:


“I don’t like shopping at Wal-Mart at all. But… if Target continues its practices of not phasing
out PVCs. Yeah, then definitely I would choose one of their competitors, and if it had to
be Wal-Mart, I guess it would have to be Wal-Mart.”


However, at this point, Target Spokeswoman Brookter doesn’t think the company will
lose business on this single issue.

Rooftop Wind Power

  • Power lines lead from a wind turbine placed near a coast to catch steady breezes. New designs for smaller turbines might be used in urban areas where wind is more turbulent. (Photo by Lester Graham)

The government wants 20% of the
energy generated in the nation from renewable

that goal. Lisa Ann Pinkerton reports experts

The government wants 20% of the
energy generated in the nation from renewable
resources. Today, we’re at a mere fraction of
that goal. Lisa Ann Pinkerton reports experts
believe the US could get there sooner if wind power
technology can be moved successfully to where the
electricity is actually consumed, America’s
cities:


Right next to Lake Erie, a large wind turbine spins hypnotically in the
breeze. Its three big propeller blades provide only around 6% of
the energy consumed at the museum where it’s located, the Great Lake
Science Center. So the big turbine is mainly for educational purposes.
The museum’s Executive Director, Linda Abraham Silver says turbine
catches the steady winds off the lake:


“We don’t want turbulence, that’s right. Steady wind is what produces
the best energy and saves the gears and instrumentation inside.”


The single wind turbine stands in a wide open space near Lake Erie, but here
on the streets of downtown Cleveland, the wind is blustery and
unpredictable. These conditions are hostile to traditional turbines.
So the conventional wisdom was wind power couldn’t flourish in urban
environments… that is, until now.


“I think the problem was the propeller, not the whole idea that wind
power was somehow unable to be captured in the city. Some people even tell
you there is no wind power in the city”


Bill Becker is an urban wind developer from Chicago. He’s abandoned the three-propeller design for a horizontal one.
And it kind of looks like a metal DNA double-helix strand. He says it’s
actually two turbine designs in one so the machine can function in low and high winds. The turbine, manufactured
by Aerotecture, is a lot smaller than traditional ones so it can be mounted on rooftops. Becker’s installed 16 on skyscrapers in
Boston and Chicago. They can generate enough electricity to power two homes annually in a typical breezy day.


Becker’s not the only inventor who thinks there are better alternatives
to expansive turbine wind farms sprouting up on ridges and bluffs
across the country. And in England, the three-blade concept isn’t dead
yet.


The company Quiet Revolution has a vertical turbine with blades curving
up and down it. It creates power in even the slightest breeze, but that
power isn’t any more than Becker’s model and it costs 4 times as much.


Instead of catching open wind, in California entrepreneurs are
capturing a very specific type of wind: breezes traveling up and over
building parapets. Those are walls that extend past the roof lines of
big box retailers and factories:


“There’s a potentially great wind resource on those buildings that’s
not being tapped into today.”


Spokesman Steve Gitlin says the company AeroVironment is tapping into
this wind with systems of 15 turbines each. These futuristic rotating
fans, each about six feet tall, line the parapets of flat-roofed
buildings:


“What we’ve done is figured out there’s a unique acceleration of wind over that edge of the building
so the turbine’s designed to actually extend above and angle slightly downward
over that acceleration zone.”


The AeroVironment system is the most expensive… six times as much as the Aerotecture double-helix
design and generates slightly more electricity. It does, however, operate in very low wind, five miles per hour or less.


Ken Silverstein says this range in cost and efficiency shows the urban wind industry is
still growing. He edits Energy Biz magazine, and
adds to make an impact on the market, these turbine costs must come
down. And the government could help jumpstart the industry:


“It needs to develop, it needs to reach economies of scale so that the
technology improves, so that the costs come down and so that wind becomes more widespread than it is today.”


But Silverstein says, urban wind designs like these offers the hope
that businesses and even homeowners could capture the energy of the wind
directly on their own.

States Pass Feds on Invasives Law

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.

Locally Grown Food Sprouts in Restaurants

  • More people want to get locally grown food. Restaurants are picking up on the trend, but there's a shortage of farmers growing local produce. (Photo by Lester Graham)

One of the hot trends expected in restaurants this year is

farm country. Julie Grant tells the story of one restaurant

One of the hot trends expected in restaurants this year is
the use of locally-grown, seasonal foods. But finding those
products can be challenging for chefs, even in the middle of
farm country. Julie Grant tells the story of one restaurant
that’s closing after years of seeking out local meats and
vegetables:


All Parker Bosley ever wanted was food that tasted good.
He’s a chef and he wanted his food to be satisfying, but
when he got into the restaurant business more than twenty
years ago he thought something was wrong with the food he
was cooking:


“I thought, there’s something wrong with this business in that
I don’t think my food was that great, even though I’m cooking very well.”


Bosley decided the problem was that he wasn’t starting with
good enough ingredients, and that mediocre ingredients
couldn’t create great-tasting food:


“And I thought about it, and I thought, I don’t have real chickens,
I don’t have good tomatoes, I don’t have good lettuce, and so forth…
it’s coming through a commercial source, so I thought, something’s wrong here.
I used to have wonderful chickens and wonderful tomatoes and strawberries when I was
growing up on a farm in Ohio…what happened to that?”


Bosley is probably Cleveland most highly-renown gourmet, but he decided
to put on his boots and headed home to the farm. Well, it wasn’t exactly his farm, but
he started driving around unnamed country roads. He was looking for small farms and road-side stands.
He’d use the chickens, eggs, tomatoes he brought back to
create dishes at his restaurant, and he liked the results:


“Once I got started and into that and realized, I was right, I was correct
your food cannot be better then the food with
which you begin.”


Bosley built his reputation, his restaurants, and his menu by
building relationships with farmers. And now nearly every
ingredient in almost every dish – from the squash and bacon
soup with hazelnuts, the mixed greens with goat cheese and
honey-thyme dressing, and even the beef medallions with
mushrooms and wine sauce – they all come from local farms.


Parker’s restaurant has been recognized more than once by
Gourmet magazine as one of the top 50 in the country, but
it’s not always easy to gather those ingredients. Sometimes
farmers just don’t have as much as the restaurant needs.
Jeff Jaskiel is Bosley’s business partner:


“We have our little qualifier in our menu, if you read it, it says ‘Sorry, we’re out
of this tonight.’ And we’ve gone through periods where we don’t have chicken on the menu for three
or four days and if you go to a restaurant and couldn’t find chicken on the menu, people would think you’re
a little bit strange.”


So, they get a lot of complaints:


“‘Why are you out of this?’ The later tables come in at 9, 9:30 and we’re out of three or four things
and they’re a little bit disappointed and we were only able to get so much in this week and I think they
try to understand and they do come back so I guess what we’re doing still means something to them.”


It’s starting to mean enough to enough people that the
National Restaurant Association expects local, seasonal
foods to be one of the hottest trends in restaurants this
year.


Lots of restaurants in New York or California already identify
exactly where each ingredient on the menu comes from, what
farm it came from, and how it was produced. But as his long-time passion
becomes hot, Parker’s restaurant is closing.


(Sound of talking)


Today Bosley is standing in the wind and cold, but it’s
still sunny outside. He’s at one of Cleveland’s newly budding farm
markets. It’s set up in the parking lot of a new outdoor
shopping mall and it’s near a new upscale neighborhood. There are
about 20 stands, with things like heritage chickens and turkeys, cheese from grass-fed cows,
and lots with apples. All the products come from nearby farms. Bosley’s call for
local produce was a big part of creating what’s now a
network of markets like this throughout the region:


“I’m doing a lot more than just making good food and maybe buying direct from a farmer. I am
doing the right thing for the environment, I am doing the right thing for rural
communities, I am doing the right thing for urban communities. I never start out, oh, I want to
be an environmentalist, and I’m going to out and hug trees and save the countryside. I just
want good food, which, if you pursue it correctly, you will be
an environmentalist.”


Bosley’s 68 now and he sees the next phase of his career in
encouraging more farmers to grow gourmet mushrooms, make
goat cheese, or build greenhouses so that there’s lettuce other
produce available for the growing market of chefs and other
people who want good local food year round.

Pros and Cons of Offshore Wind Farms

  • While the tower is around 3 miles north of Cleveland's shore, a viable wind farm would need to be at least 6 times farther out in Lake Erie. The wind monitoring tower measures the speed, direction, and height of Lake Erie's wind to determine if wind power generation on the lake is economically viable.

Proposals for offshore wind farms, from the coasts of Texas to New England have the potential to generate more electricity than land turbines do. Lisa Ann Pinkerton reports these projects face various hurdles to becoming reality, but they’re not completely insurmountable:

Transcript

Proposals for offshore wind farms, from the coasts of Texas to New England have the potential to generate more electricity than land turbines do. Lisa Ann Pinkerton reports these projects face various hurdles to becoming reality but they’re not completely insurmountable:


Over the past few months, whenever the weather is favorable, Aaron Godwin of Green Energy Ohio rides a power boat several miles out into Lake Erie. Out on the on the city of Cleveland’s century old water intake structure he’s built a tall wind monitoring tower.


“The upper part of the tower is about 168 feet above the water, so we’re measuring at about 30, 40 and 50 meters, and dual instrumentation at each level, anemometers that measure wind speed and vanes that measure direction.”


Godwin’s got almost a year of wind data and today he’s installing a small wind turbine to confirm what he’s discovered: that the lake’s wind is roughly twice as strong as wind on land. So to Godwin offshore wind farms are inevitable, especially since 75 percent of the nation’s energy use is near coastal cities.


However, proposed projects everywhere face a number of hurdles. One of them is bird and bat migration. Some land turbines have killed creatures that flew too close. But in Denmark, where offshore wind is 15 years old, extensive water foul surveys show little change in bird behavior. Charlotte Boesen is an environmental planner for Dong Energy in Denmark.


“These birds, they do fly around the wind farm. They do not like flying over land you can say and maybe they in some sort they perceive the turbines or wind farm as a similar object.”


Even so, no wind project in the US will ever get off the ground without a full assessment of potential wildlife impacts. That’s why 60% of Lake Erie has already been ruled out by a preliminary study conducted by the wind consulting firm AWS True Wind. Its Executive Director Bruce Bailey says that leaves most of eastern Lake Erie still available, with the best wind about 15 miles northwest of Cleveland.


“That’s where the strongest winds would be found. With water depths still being under say 70 feet.”


Bailey adds the shallow depth of Lake Erie combined with its solid lake bottom and fresh water makes it more friendly to offshore wind generation than oceans.


“You wouldn’t have to deal with the corrosion or the extra cost to safeguard your hardware from corrosion if you’re sighted in a fresh water lake.”


Bailey adds designing against hurricanes makes ocean projects more expensive. On the flip side, Lake Erie’s been known to freeze.


“There are ways to deflect the ice from actually pushing too strongly against or lifting out a turbine foundation. Some of them have already been deployed already in offshore projects in Northern Europe, and some of them are located in locations where you might even get icebergs.”


Another concern is whether these turbines will ruin the natural beauty of America’s Coastlines, even though on the horizon a turbine might only look a big as a thumbnail. Walt Musel of the US Department of Energy says this worry is unfounded.


“It’s worth noting there are no projects in the United States, so most people who object to offshore wind have never seen one.”


Fifteen years ago, projects in Denmark faced the same prejudice. Today tourists rent boats to go see them.


Above all, perhaps the largest impediment to offshore wind power is its high cost. Installation in water is expected to be double the cost of on land construction. However, once farms are producing power, electricity companies are open to buying it.


Out on Lake Erie, Aaron Godwin is packing up his tools for the day. He says there is an up side to those high capital costs. He says in the future, turbines will be so large it’ll make more sense to manufacture the parts locally, giving America’s manufacturing industry a ray of hope.


“Energy is a guaranteed growth market. Wind power is the fastest growing energy sector in the entire world. Why would you not want to get involved in that guaranteed growth market? It just does not make sense.”


Godwin says if the US can clear these hurdles of public perception, engineering, and environmental impacts, he thinks the US economy might find a pleasant surprise: consistent, green energy, built and harnessed off the blue coasts of America.

Ten Threats: Demand for Drinking Water Increasing

  • Water diversion is an increasing threat to the Great Lakes. As communities grow so does the demand. (Photo by Brandon Bankston)

We’re continuing the series, Ten Threats to the Great Lakes. Our field guide through the series is Lester Graham. He says our next report looks at where the demand for water will be greatest:

Transcript

We’re continuing the series Ten Threats to the Great Lakes. Our field
guide through the series is Lester Graham. He says our next report looks
at where the demand for water will be greatest.


Right around the Great Lakes is where there’s going to be more demand
for drinking water. Water officials say as cities and suburbs grow, so
does the need for water. Some towns very near the Great Lakes say they
need lake water right now, but in some cases they might not get it. The
Great Lakes Radio Consortium’s Christina Shockley reports:


People who live around the Great Lakes have long used the lakes’ water
for transportation, industry, and drinking water. Most of the water we
use, gets cleaned up and goes back in the lakes.


That’s because the Great Lakes basin is like a bowl. All the water used
by communities inside that bowl returns to the lakes in the form of
groundwater, storm water runoff, and treated wastewater, but recently, thirsty
communities just outside the basin—outside that bowl—have shown an
interest in Great Lakes water.


Dave Dempsey is a Great Lakes advisor to the environmental group
“Clean Water Action.”


“We are going to be seeing all along the fringe areas of the Great Lakes
basin all the way from New York state to Minnesota, communities that
are growing and have difficulty obtaining adequate water from nearby
streams or ground water.”


Treated water from those communities won’t naturally go back to the
basin. Treated wastewater and run-off from communities outside the
Great Lakes basin goes into the Mississippi River system, or rivers in the
east and finally the Atlantic Ocean.


The Great Lakes are not renewable. Anything that’s taken away has to be
returned. For example, when nature takes water through evaporation, it
returns it in the form of rain or melted snow. When cities take it away, it
has to be returned in the form of cleaned-up wastewater to maintain that
careful balance.


Dave Dempsey says the lakes are like a big giant savings account, and
we withdraw and replace only one percent each year.


“So, if we should ever begin to take more than one percent of that
volume on an annual basis for human use or other uses, we’ll begin to
draw them down permanently, we’ll be depleting the bank account.”


Some of the citiesthat want Great Lakes water are only a few miles from
the shoreline. One of the most unique water diversion requests might come
from the City of Waukesha, in southeastern Wisconsin. The city is just 20 miles
from Lake Michigan. Waukesha is close enough to smell the lake, but it
sits outside the Great Lakes basin. Waukesha needs to find another
water source because it’s current source – wells—are contaminated with
radium.


Dan Duchniak is Waukesha’s water manager. He says due to the city’s
unique geology, it’s already using Great Lakes water. He says it taps an
underground aquifer that eventually recharges Lake Michigan.


“Water that would be going to Lake Michigan is now coming from Lake
Michigan…. our aquifer is not contributing to the Great Lakes any more,
it’s pulling away from the Great Lakes.”


Officials from the eight Great Lakes states and Ontario and Quebec
recently approved a set of rules that will ultimately decide who can use
Great Lakes water. The new rules will allow Waukesha—and some
other communities just outside the basin—to request Great Lakes water,
and drafters say Waukesha will get “extra credit” if it can prove it’s
using Lake Michigan water now.


Environmentalists are still concerned that water taken from the Lakes be
returned directly to the Lakes, but some say even that could be harmful.


Art Brooks is a Professor of Biological Sciences at the University of
Wisconsin- Milwaukee. He says the water we put back still carries some
bi-products of human waste.


“No treatment plant gets 100 percent of the nutrients out of the water,
and domestic sewage has high concentrations of ammonia and
phosphates. Returning that directly to the lake could enhance the growth
of algae in the lake.”


That pollution could contribute to a growing problem of dead zones in
some areas of the Great Lakes. Brooks and environmentalists concede
that just one or two diversions would not harm the Great Lakes, but they
say one diversion could open the floodgates to several other requests, and
letting a lot of cities tap Great Lakes water could be damaging.


Derek Sheer of the environmental group “Clean Wisconsin” says some
out-of-basin communities have already been allowed to tap Great Lakes
water under the old rules.


“The area just outside of Cleveland–Akron, Ohio– has a diversion
outside of the Great Lakes basin, so they’re utilizing Great Lakes water
but they’re putting it back.”


There are several communities that take Great Lakes water, but they, too,
pump it back. The new water rules still need to be ok-ed by the legislature of
each Great Lakes state, and Congress. Since the rules are considered a
baseline, environmental interests throughout the region say they’ll lobby
for even stricter rules on diversions.

Point source pollution means just that. It’s pollution that comes from a
single point; usually out the end of a pipe. It’s easy to identify. Since
the passage of the Clean Water Act more than 30 years ago, most of that kind
of pollution has been cleaned up, but today, there are still some pipes dumping
pollution into lakes and rivers, but Mark Brush reports stopping that remaining
pollution isn’t that easy:

of a threat called point source pollution.


Point source pollution means just that. It’s pollution that comes from a
single point; usually out the end of a pipe. It’s easy to identify. Since
the passage of the Clean Water Act more than 30 years ago, most of that kind
of pollution has been cleaned up, but today, there are still some pipes dumping
pollution into lakes and rivers, but Mark Brush reports stopping that remaining
pollution isn’t that easy:


(Sound of the Maumee)


We’re on the banks of the Maumee River near Toledo, Ohio. Sandy Binh
brought us here to describe what she saw in the river several years ago when
she was out boating with some friends.


“When there was a heavy rain maybe five years or so ago this is where we saw
a sea of raw sewage in this whole area. It was like, I mean it was like chunks
everywhere. It was just disgusting.”


Binh reported it and found that the city couldn’t do anything about it. That’s
because Toledo’s sewage treatment plant is at the end of what’s called a combined
sewer system. These systems carry both storm water from city streets, and raw
sewage from homes and businesses. If too much water comes into the plant, a
switch is flipped, and the sewage goes straight into the river.


(Sound of treatment plant)


Steve Hallett manages engineering at the wastewater treatment plant for the
city of Toledo. He says a rainstorm can bring twice as much water as the
plant can handle.


“And when hydraulically you can only take about 200 million of it – where’s
the other 200 hundred million go?”


“Where does it go?”


“Uh, it’s by-passed. Limited treatment possibly and then it would be
by-passed to the Maumee River”


Toledo is not alone. More than seven hundred cities across the country have
combined sewer systems that often overflow, cities such as Milwaukee,
Detroit, Buffalo, Chicago, and Cleveland. Every year billions of gallons of
raw sewage are dumped into the Lakes from cities with these old combined systems.


The sewage can cause problems for the environment, but the biggest concern
is that people might get sick. Some of the bugs found in sewage can cause
liver problems, heart disease, and can even cause death.


Dr. Joan Rose is a microbiologist with Michigan State University. She’s
been studying sewage in water for more than 20 years. She says sewage
contains viruses and other nasty microorganisms that can hang around in the
environment.


“Up here in the Great Lakes region with the cool temperatures we have –
these organisms can survive for months, and also these organisms
accumulate.”


Rose says what’s unique about the microorganisms in sewage is that it only
takes a few of them to cause diseases in humans, and once contracted they
can be contagious.


The Ohio EPA sued the city of Toledo. It wanted the city to clean up its
act. After a long battle, the city and the state reached a settlement, and
officials agreed to spend more than 450 million dollars to try to do
something about the problem.


(Sound of construction)


Back at the wastewater treatment plant we’re standing on the edge of a deep
pit. Down at the bottom sparks are flying as welders climb over towers of
green rebar. They’re building a new system that’s designed to treat water
quickly when there’s a heavy rainstorm. The water won’t be fully treated,
but the solids will be settled out and the water will be chlorinated before it’s
released into the river. It’s a compromise the city and the state EPA agreed
upon.


Steve Hallett says to fully treat every drop of water that comes to the
treatment plant in a big storm would require a project four times this size.


“You’d need massive amounts of storage to hold every drop here. You know, that’s
extremely costly and I think, uh, is deemed not feasible.”


Toledo’s project will mostly be paid for by a steady hike in water and sewer
rates over the next fifteen years. The increase was approved by voters
three years agom, and officials plan to go after federal grants and loans
to help defray the costs, but federal dollars are getting scarce. Big cuts
have been made to the federal low interest loan program many cities use to
finance these projects.


The demand for financing is likely to increase. The cost of upgrading the
nation’s combined sewer systems will cost hundreds of billions of dollars.
The question is, who will pay to stop one of the biggest sources of water
pollution left in the country?

Ten Threats: Canals Past and Present

One of the Ten Threats to the Great Lakes identified by experts across the region is the possible
expansion of canals to allow larger ocean-going ships into the lakes. Some see the expansion of
shipping channels as a threat to the environment; others see it as great economic opportunity.
Just like in the early days of settlement, they see the shipping channels on the Great Lakes as
a way to make trade opportunities better.

In our next report from the series, “Ten Threats to the Great Lakes,”
Lester Graham brings us a look at shipping on the lakes. Some people think
bigger ships could bring more trade to the region:


One of the Ten Threats to the Great Lakes identified by experts across the region is the possible
expansion of canals to allow larger ocean-going ships into the lakes. Some see the expansion of
shipping channels as a threat to the environment; others see it as great economic opportunity.
Just like in the early days of settlement, they see the shipping channels on the Great Lakes as
a way to make trade opportunities better.


Native Americans had canoe trade routes on the Great Lakes long before the Europeans appeared
on the scene. When French fur traders arrived, they copied what they saw. They built birch-bark
canoes to travel the lakes and to haul back fur pelts.


(Sound of Saginaw Voyageurs paddling and singing “Alouette, gentile Alouette…”)


Chuck Hoover is with the Saginaw Voyageurs, a group of re-enactors who re-trace the French
Voyageurs routes. Hoover says the large canoes were great until you ran into rapids on the rivers
connecting the lakes.


“What you had to do was pick up everything, including the boat, and carry it across the dry land to
the next place that you could put in water that was navigable.”


Those portages could be as long as seven miles. Carrying a canoe big enough to haul more than a
dozen men and the heavy bundles of fur pelts was a tough job and it slowed trade. So, some small
canals were dug to make passage easier. As the region developed even more valuable natural
resources were discovered. Bigger canals were needed.


Stanley Jacek is an Area Engineer with the U.S. Army Corps of Engineers at the canal and locks
at Sault Ste. Marie, Michigan. He says by the middle of the 1800s mining around Lake Superior
had become big business.


“Back in those days they discovered iron ore and copper in the upper end of the lakes here. So,
they had to get all that commerce down to the heartland of the country, so locks had to be
built.”


With a canal and locks to help ships negotiate the drop from one lake level to the next, the ore
could be transported to the big steel mills in industrial cities such as Cleveland and Gary, Indiana.


Christopher Gilchrist is with the Great Lakes Historical Society. He says you can’t underestimate
the value of those canals.


“The water-borne transportation was critical for the creation of the industrial age in U.S. history.
There’s a reason why the steel mills are located right on the banks of these Great Lakes. All the major
steel mills were located right by the water so that they could get their raw materials cost
effectively.”


At the other end of the Great Lakes the St. Lawrence Seaway opened in the 1950s to make it
possible for ships on the Atlantic Ocean to enter the lakes, and another big canal and set of
several locks overcame another obstacle to shipping on the Great Lakes – The Niagara Falls.


The Welland canal allows ships to go around Niagara. Since it first opened in the 19th century the
Welland canal and its locks have been enlarged four times. Each time the Welland canal locks
and the St. Lawrence Seaway have been made wider and deeper, the shipping industry builds
bigger and bigger ships to the point that they literally just squeak through…


(Sound of ship squeaking against timbers)


…Often rubbing up against the timbers that act as bumpers on the locks’ concrete walls.


Throughout the history of the canals, there’s been pressure to make them bigger and bigger.
Many feel the amount of shipping through the canals is tied directly to the economic well being
of the nation. The more the canals can handle the better the economy.


(Sound of buzzing, roar of compressor)


Back at Sault Ste. Marie, the locks open to allow another big ship through.


Stanley Jacek, the engineer at the Soo Locks connecting Lakes Superior and Huron says the
economic impact is pretty easy to track.


“What we do here in the way of passing of commerce mimics what’s happening in the country. You
can actually see spikes in the economy by looking at our traffic here.”


But some say the canals could do more than just reflect the health of the economy. They could
spur the economy if even bigger ships could come into the lakes. The ships, the kind carrying
containers ready to be pulled by trucks or loaded on rail cars, could go directly to Great Lakes
ports instead of ports on the East or West coasts. More direct shipping might improve the
region’s economy.


But environmentalists are worried. They say bigger ships from all over the world might mean
more alien invasive species damaging the Great Lakes. The wider, deeper channels might
damage the environment along scenic rivers connecting the lakes, and some believe expanding
the channels will let too much water flow out of the lakes that could worsen the problem of lower
lake levels seen in recent years.


The plans for bigger ships are on hold for right now. But, given the history of the canals, many
believe expansion is only a matter of time.

In recent decades, rust-belt cities have seen neighborhoods deteriorate and surrounding suburbs sprawl with little restraint. Now, formerly industrial cities are looking to redevelop old neighborhoods and attract new people. The Great Lakes Radio Consortium’s Lisa Ann Pinkerton looks at how one old neighborhood is using sustainable ideas to attract new residents:


(sound of street)


The morning sun is peaking through an overcast sky along a street lined with simple Victorian style homes. In this Cleveland neighborhood, two of these homes are brand new. Unlike their century old neighbors, they’re green buildings… built with the environment in mind.


One, is the home of David and Jen Hovus. It was built to actively conserve resources and to have a low impact on the environment. For example, all of the lights are on timers.


“I had to go out of my way to find timers that would control compact fluorescent lights, so that I wasn’t wasting too much electricity.”


Even the fan venting moist air from the bathroom… is on a timer. The furnace too, is a high-efficiency unit.


(sound of walking)


Hovus’s environmentally friendly surroundings don’t stop at the backyard gate. He lives in a special neighborhood called the Cleveland EcoVillage. And on his way to work, he sees green building principles and sustainable practices all along the way. Like the community garden, where even the tool shed is made of recycled material.


“There was a 120-year-old maple tree that was cut down. Folks brought a portable saw mill and they sawed it into lumber and that’s what they used for the framing. It’s actually a strawbale construction as well.”


The idea to revive a struggling neighborhood with sustainable solutions, started with the city’s environmental planning organization, EcoCity Cleveland. Back in 1997, they investigated dozens of the cities neighborhoods. And choose the west side neighborhood where Hovus lives, because it was close to transit, had a strong Community Development organization and had support of the local councilman.


David Beach is EcoCity Cleveland’s Executive Director. He says besides environmentally sound buildings, the neighborhood gives the option of a car-free life.


“Where everything you need is with in walking distance. So you’re living space, your work place, and some of your shopping can be right in that one neighborhood. And then you hop on that rapid transit and in five minutes your downtown or you’re at the airport.”


Everything within a half-mile radius of the transit station is in the EcoVillage.
Resident David Hovus stands at the entrance, with fierce wind coming off of Lake Erie.


“This used to be… there was literally a set of stairs leading down to the platform. There was essentially a bus shelter on the platform and that was it. And if you didn’t actually know where the entrances were, you’d never know there was a train station here.”


So EcoCity Cleveland and the neighborhood convinced Cleveland’s Transit Authority to spend nearly $4 and a half million dollars on a new station, based on environmentally sound principles. It’s the only Green Transit Station in Ohio.


“And now we’d got a nice warm building that uses passive solar heating and a lot of green building features.”


Mandy Metcalf is the EcoVillage Project Director. She continues our tour of the neighborhood down a walking path.
Four blocks later, twenty new green-built town homes come into view. In the same simple Victorian style of the neighborhood, they blend right in. They’re also very energy efficient.


“One resident said that his January bill was only forty dollars for gas, which is pretty impressive.”


But, the majority of the homes in the EcoVillage are more than a century old and very energy inefficient. While they’re considered “affordable housing,” a mortgage payment on top of a heating bill of more than $300 dollars makes them difficult to afford. So Metcalf’s organization helped homeowners discover where their energy was being wasted.


“What the best things, the most cost effective things that they could do to retrofit their houses. And now we’re going to match them up with loan programs and encourage them to go through with it.”


While older homes are being updated, the Ecovillage is making plans to improve the green space surrounding the local rec center. And within two years, they hope to entice a green building grocery store to the area.
