Scientists are investigating whether
air pollution is affecting how well students
perform. Lester Graham reports:

Researchers say we might be building schools in the wrong places. We build them
near interstates full of polluting cars and trucks, and we build schools downwind of
factories. Kids might be getting a big dose of air pollution everyday they’re at school.

Researchers at the University of Michigan want to look at whether it’s actually
affecting kids. Paul Mohai is the lead researcher.

“School-aged children are particularly vulnerable because their bodies are growing.
They’re considered a vulnerable population and that’s all the more reason we should
be looking at the toxic burden that they may face, both in the schools that they go to
and where they live.”

Mohai and his colleagues will look at all the social and economic issues, and then air
pollution to see if it’s a factor in school kids’ health and academic performance.

FIGHT FOR AMERICA’S LONGEST RIVER (Part 1)

  • Wing dams along the Missouri River force the flow of water to the center, scouring the bottom of the river. Environmentalists say the Missouri has been turned into little more than a big ditch for barges. They support management plans that restore habitat for wildlife. (Photo by Lester Graham)

Rivers have been the life-blood of commerce in the United States since the
nation’s beginning. In 200 years, the machines of trade have evolved from flat-
bottomed wooden boats to today’s steel-hulled river barges. The rivers link
America’s natural resources with the industrial cities that propel its economy.
Decades of damming and dredging have turned the big rivers into shipping
channels. But in recent years, competing interests have argued in defense of
other uses of the rivers. In the first of three reports, Kevin Lavery looks at how
those groups seek to balance the economy and ecology:

Rivers have been the life-blood of commerce in the United States since the
nation’s beginning. In 200 years, the machines of trade have evolved from flat-
bottomed wooden boats to today’s steel-hulled barges. The rivers link
America’s natural resources with the industrial cities that propel its economy.
Decades of damming and dredging have turned the big rivers into shipping
channels. But in recent years, competing interests have argued in defense of
other uses of the rivers. In the first of three reports, Kevin Lavery looks at how
those groups seek to balance the economy and ecology:


Long before interstates and over the road trucking, America moved its goods on
the water. River barges carry just about any kind of commodity. They emit less
pollution than trucks and trains… and the river route is cheaper than both the road
and the rail.


The nation’s farms, coal mines and quarries depend on rivers like the Mississippi,
Ohio and Missouri to keep their products moving. Business is healthy on the
Mississippi and the Ohio. But on the Missouri, barges carry just a third of the
cargo they did 30 years ago. Many shippers say drought and overregulated dam
releases make the water levels too unreliable to plan the big hauls that bring in
the most profit.


Paul Davis runs Interstate Marine Terminals, 200 miles upstream from where the
Missouri River meets the Mississippi, near St. Louis. He ships and stores
fertilizer from his dock. But Davis says when the river runs low, barges are not
his best option:


“The real adjustment that I’ve made is going from river to rail.”


Logistically, the adjustment is easy. The Union Pacific railroad line runs just a
few feet from Davis’ dock. But it costs him about 15 dollars more per ton to move
goods by rail. Davis says river barges might be profitable again if old feuds over
water management would end:


“There’s business out there. It could come back if people quit fighting and start agreeing
and confidence would return to shipping on the Missouri River. But I can’t afford to wait
and see… I’ve got to make adjustments.”


The fighting puts business against the environment. Shippers want enough
water to move freight. But environmentalists want the river to rise and recede
like it did before the Army Corps of Engineers started changing it.


The conflict goes back to the 1930’s. Congress ordered the Corps to make the
river safe for barges. That meant clearing snags and sandbars from a 735-mile
stretch from Sioux City, Iowa to St. Louis, Missouri. The Corps also confined the
river with earthen levees. Opponents say it turned the Missouri into a
characterless ditch.


The Corps spends 7 million dollars a year to maintain the channel. Spokesman
Paul Johnston says despite the dwindling volume of river traffic, the Corps is
mandated to keep the river open:


“The Corps of Engineers, like any federal agency, does not have the option to pick and
choose which laws it’s going to obey and not obey.”


But critics say wildlife has paid for the Corps’ mandate. Over the years, dams
and channels eliminated a half a million acres of wetland habitat. Birds lost their
sandbar nesting grounds, and fish no longer found shallow backwaters to lay their
eggs.


Among the hardest hit animals is the pallid sturgeon. It’s a long, flat-nosed fish
that dates back to the T-Rex. It’s been around 70 million years, and for the last
17, it’s been on the endangered species list.


Chad Smith directs the Nebraska field office of the environmental group
American Rivers. He says the pallid sturgeon’s fate shows the whole river is in
jeopardy:


“When it starts to decline, you know, that kind of creature that’s so in tune with the
Missouri as it was, is an indicator that maybe something’s not right, and it’s going to be
the first thing to fall.”


So Congress told the Corps to take on a recovery mission. The agency spends
more than 50 million dollars a year to rebuild shallow water habitat for fish and
birds. The Corps hopes a water resources bill pending in Congress will increase
its habitat restoration budget to 80 million dollars.


In 2006, the Corps launched its most controversial restoration program to date. It
released extra water from a South Dakota reservoir to mimic the natural flood
pulse that occurs on the Missouri River every spring. That triggers the sturgeon
to spawn.


Conservationists herald last year’s man-made spring rise as a long overdue sign
of progress. But barge companies on the lower Missouri are upset. They say
the spring rise brings a drop in the river’s depth in the summer… which means
less cargo they’re carrying and less money they’re making.

Better Life in the Burbs?

  • New construction continues to spread into the countryside. A new study looks at the quality of life in these suburban developments.

People who move to the suburbs often say they’re escaping the stress of the city. But researchers are finding the suburbs cause a lot of stress for residents too, and the difference doesn’t seem to be as much about where you live as it is about how you live.

People who move to the suburbs often say they’re escaping the stress of the city. But researchers are finding the suburbs cause a lot of stress for residents too. And, the difference doesn’t seem to be as much about where you live as it is about how you live. The Great Lakes Radio Consortium’s Lester Graham reports.


Ahhh, living in the suburbs, quiet tree lined streets, green lawns, and in the distance a glimpse of undisturbed woods along a creek or maybe farmland rolling off to the horizon. Across the Great Lakes region, the suburbs are picture perfect. Well, maybe not quite perfect.


A group of researchers has been spending a lot of time in the sprawling Chicago suburbs to see what draws people to the area, what they like, don’t like, from where they move and whether they intend to stay where they are, in the ‘burbs. What they’ve found is that living in the suburbs is not quite as stark or as bleak or as sterile as some of the popular press portrays it. But at the same time it’s not as blissful as the images in the brochures printed up by developers.


Charles Cappell is a sociologist at the Social Services Research Institute at Northern Illinois University. Since 1991 he’s been conducting surveys of people living in the suburbs. Mostly it’s been about why they live there. Usually the participants talk about their children, safety for their kids, nice schools, and nice green space for the family. But, recently Cappell and his team have been probing a little more deeply.


“In subsequent surveys, in 2000 for example, we did measure stress and we do know that suburbanites experience stress. They’re stressed from the demands of suburban life, some of the friction. But, in general, they report a fairly good quality of life.”


Of course, part of that quality of life is due to the surroundings. But after moving to the suburbs many people miss some of the more urban conveniences. And so as the housing developments sprout, the retailers are paving parking lots right behind them.


“This is one of the contradictions of suburban life: they value the quiet, green, suburban lawns and openness, and they crave the convenience of the shopping malls.”


But with that convenience comes the inconvenience of congested traffic on roads not designed to carry such huge volumes. While cities and counties spend untold millions of dollars widening old roads and building new ones, the suburbanites cope with the stresses of back-ups.


Rich Green is a geographer at Northern Illinois. He’s watched as the suburbs have spiraled out away from Chicago, causing an intricate and massive spider web of new roadways. Still, some politicians are calling for more and bigger roads in the suburbs. U.S. House Speaker Dennis Hastert is calling for an interstate to be built in his district that will create a new outer-belt for the Chicago metro area, some nearly 50 miles away from downtown. But Green says the Interstates in the Chicago area have simply created corridors of development. Instead of relieving traffic, some experts say the interstates around Chicago have simply given sprawl better access.


“Clearly, building these interstates hasn’t corrected some of the problems that people were hoping for. Usually, if you expand a highway, you bring more people.”


Traffic hassles are not the only stress suburbanites face. In fact, the more serious stressors have to do with the cost of living there. During the heady days of the stock market boom, people started building bigger and better houses out on one acre lots on the fringes of the ‘burbs. Now, because of the poor performance of the markets, those houses –sometimes derogatorily called ‘McMansions’– are extravagances that some suburbanites are struggling to afford. But if they want to live in the new Chicago suburbs, they don’t have much choice. Prices have skyrocketed and there’s very little in the way of affordable housing being built.


Dick Esseks is a retired professor who’s been doing research for the American Farmland Trust. The Trust is concerned about the loss of farmland due to development. Esseks says many of those who moved to the suburbs did so when times were good, but with the downturn in the economy, some of those people face forced early retirement.


“When they go from full-time workers to pensioned workers, can they find housing in the same community, stay in the same church, stay in the same synagogue, stay in other associations?”


Esseks says because many of the municipalities require large lots, have very high standards for construction, and agree to annex large subdivisions of ‘McMansions,’ they leave behind the chances for more affordable housing. Only the very well off can afford to live in many of the suburbs.


Still, even with the weight of big mortgages hanging over their heads, bad traffic congestion, and other stresses, researchers have found suburbanites seem to cope better on average than their counterparts in the city. Sociologist Charles Cappell says there’s a reason for that, and it has to do with who lives in the suburbs. Cappell says it’s established that married people and people with families tend to deal with stress better than single people. Older people are less stressed than young people, and the suburbs have a much greater ratio of traditional families with middle-aged parents than in the city.


“Some of the differences between quality of life between urban and suburban experiences can be attributed to the fact that urban places are more stressful or there are higher levels of stress because of these reasons. There’s more single people. They’re younger. But, the sources of stress, environmentally, may be different, but I think the bigger indicators of stress are your kind of social environment, your psychological space, how you cope, what kind of support you have and families in spite of their increased burdens on time, really do offer emotional support.”


So, people in the ‘burbs’, generally speaking, have a better support structure at home, and usually have the means to pay for a more comfortable, less stressful life to begin with. Cappell says getting out of the city and into the suburbs is not the answer to a stress-free life, but it just so happens there are a lot of people who live in the suburbs who are better able to cope with life’s stress.
