School Districts Encouraging Urban Sprawl?

Each year, Americans build a staggering one and a half million new
homes. A lot of environmentalists say too many of these houses are big,
single family homes on spacious lots. They say that wastes farmland and
natural areas, but suburban planners say they’re forced to build that way
by local governments, such as school districts. The GLRC’s Shawn
Allee has more:


Jamie Bigelow makes a living building houses in suburbia. He takes a
dim view of his profession. For Bigelow, most suburbs don’t let
neighbors be… well, good neighbors. After all, homes are too far apart
for people to really meet one another and everyone has to drive far for
work or to just go shopping. According to Bigelow, families are looking
for something better.


“We believe there’s a growing market for people who want to be
interconnected and live in interconnected neighborhoods and housing,
primarily in the suburbs, no longer supplies that.”


So, about ten years ago, Bigelow and his father tried building one of these
interconnected neighborhoods in a Chicago suburb. They wanted shops
and parks nearby. They also wanted to close some streets to cars, so kids
could play safely near home, but one detail nearly derailed the project.


Under the plan, houses would sit close together on small lots. The local
zoning board hated this idea. According to Bigelow, they said small houses
would break the local school district’s budget.


“They want large houses on large lots, because for the school district,
that will give them a lot of taxes with not as many kids because there’s
not as many houses.”


The planners wanted Bigelow to build bigger, pricier houses. Bigelow and his
family fought that and eventually won. They did build that compact suburban
neighborhood, but victories like that are rare. Often, the area’s local
governments try to protect schools’ tax revenue by promoting large homes and lawns.


“They’re actually behaving, or reacting, very rationally.”


That’s MarySue Barrett of the Metropolitan Planning Council, a
Chicago-based planning and advocacy group. She says growth
sometimes overwhelms schools, and it can catch taxpayers and parents
off guard.


“They don’t have the revenue from their local property tax to pay for
hiring new teachers, so their class sizes become thirty-two, thirty-three.
And that family who said, Wait a minute, I came out here for good schools, now
I’m going to an overcrowded school? It’s the last thing I thought was
going to happen.”


From the schools’ perspective, larger lot sizes solve this problem. Big
lots mean fewer kids per acre. Larger houses bring in more property
taxes. That means higher taxes cover costs for the few kids who do
move in.


Barrett says the trend’s strongest in states like Illinois, where schools rely
heavily on property taxes. She says in the short term, the strategy keeps
schools flush, but it also pushes the suburban frontier outward, into rural
areas. That wastes land and hurts our quality of life.


(Sound of kids coming out of school)


The day’s over for this high school in Northern Illinois. A throng of
teens heads toward a line of thirty yellow school buses. Some of them
spend up to three hours per day riding between school and home.


Inside, Superintendent Charles McCormick explains what’s behind the
long rides. He says the district’s large size is partly to blame, but there’s
another reason. The area’s subdivisions are spread among corn fields,
far from existing towns and from each other.


“Well, the land use pattern itself disperses the students, so when you look
at what bus routing means, the position of one student can add ten to
fifteen minutes to a route.”


McCormick says local governments in his school district encouraged big
homes and lots, but even his schools can barely keep up with the costs of
educating new students. He says suburban planners just can’t risk
bringing in smaller homes and more kids.


“Well, if you were to run a business the way growth affects school districts,
you’d be broke because you cannot keep up with rapid growth that produces
for every student, a deficit.”


That’s because even high property taxes don’t fully pay for each
student’s education.


Land use experts say reliance on property taxes for education puts
suburbs in a tight spot. Some want to try allowing smaller homes or
even apartments, but school funding’s a stumbling block.


Like other reformers, MarySue Barrett has been pushing for an
alternative. She wants state government to kick in a bigger share of
education dollars. The idea’s to have enough funding for each kid, regardless
of how large or expensive their home is.


“And if we have a different way of paying for our schools that’s less
dependent on the property tax, we’ll begin to move away from this
problem that’s put a choke hold on so many communities.”


It will be an uphill fight, because states are reluctant to change their tax
structures, but Barrett says it’s the worth the political cost. She says, if
we want alternatives to suburban sprawl and its traffic congestion, we
need new ways to pay for education.

Budget Cuts to Fuel Ash Borer’s Spread?

U.S. senators are asking the Department of Agriculture for emergency funding to help control the spread of the emerald ash borer. The burrowing tiny insect has already killed millions of ash trees.

US senators are asking the Department of Agriculture for emergency
funding to help control the spread of the emerald ash borer. The
burrowing tiny insect has already killed millions of ash trees. The
emergency funding request comes as Congress has severely cut federal
funding for the program. That’s forced states to change the way they
fight the spread of the beetle. The GLRC’s Mike Thompson reports
because of the federal budget cuts and a lack of state funding, experts
fear the infestations could spread:


(Sound of chainsaw and worker)


In 2002 the emerald ash borer was first discovered in southeastern
Michigan. Soon after that federal and state officials determined the
chainsaw was the best way to fight it.


(Sound of tree falling)


Since the tiny beetle arrived, officials estimate the insect has killed – on
its own – more than 15 million trees in Michigan, Indiana and Ohio, and the
infestations keep spreading.


There is no known natural predator for the ash borer; no known
pesticide. The experts believe the only way to stop it is to destroy it by
cutting all ash trees within half a mile of a known infestation.


Dan Herms is an entomologist at Ohio State University. He serves on the
ash borer science advisory panel. He says the beetle threatens all of
North America’s 8 billion ash trees.


“If the spread of the insect can’t be contained to Michigan, it will
continue to spread to Ohio and throughout the Eastern United States,
killing all the ash trees. Essentially it’s going to do to ash what
Dutch elm disease did to elm and what chestnut blight did to chestnut.”


Over the past two years the three infested states have cut down
hundreds of thousands of ash trees to stop the spread, but cutting was the
preferred method when the federal government was picking up the tab.


In 2004, the federal government allocated some 41 million dollars for
protecting and cutting down ash trees. That funding slipped to 27
million dollars last year. In 2006 the federal government ash borer
funding has dropped to 8 million dollars – just one-fifth of what it was
two years ago.


Getting at the reasons for the budget cut is difficult. State agriculture
officials defer to federal agriculture officials who defer to Congress.


The U.S. Department of Agriculture’s Ash Borer Program coordinator
Craig Kellogg theorizes the war in Iraq and Hurricane Katrina forced
lawmakers to cut funds.


“We can always speculate between all the other programs that are going on at
USDA, the cost of war, the cost of the hurricanes and the clean-ups and
all that good stuff, but we are not at the level that we were given the full
reason why we were cut.”


So with little federal money, most of the pre-emptive cutting of ash trees
has stopped. OSU entomologist Dan Herms says he’s concerned.


“It worries me extremely because if the funding is not restored such to
allow at least the opportunity to stop the spread of the insect in northwest
Ohio it will spread throughout the eastern United States, and it will cost
hundreds of billions of dollars in damage.”


The USDA and the states have shifted focus. States will use the federal
funding they receive to monitor the spread of the insect, enforce
quarantines and educate the public. Ohio will cut trees only if they find
new infestations away from the northwest part of the state.


But if the threat is so great to Ash trees, why won’t the states spend their
own money to stop the spread of the emerald ash borer?


We asked Ohio Agriculture Department spokeswoman Melissa Brewer.


“Well, you know, the state has stepped up to the plate as far as having in kind services
and taking those programs and running with them. You know, as far as how much
money can be contributed and that kind of thing… I don’t know who to even direct you on that.”


Officials from the different states say with current state budget pressures,
it’s difficult to find the money to cut down ash trees, and now that
federal money has dried up, Indiana scientists say they’re not sure
cutting trees worked.


State officials and scientists say the emerald ash borer is a national
problem and it should be the federal government’s responsibility to pay
the protection costs.

Bed Bugs Biting Again

Health officials across the country say some nasty night critters are
making a comeback. Bed bug cases are up, and in 2005, they were reported
in 43 states. The GLRC’s Tana Weingartner reports:


It turns out your mother knew what she talking about, when she
reminded you to “sleep tight” and “don’t let the bed bugs bite.” The
blood-sucking insects are popping up in hotels and homes around the
country.


Steve Chordas is a public health entomologist with the Ohio Department
of Health. He blames increases in travel and the banning of some
pesticides for the bed bug resurgence, but, he says, the bugs are more of
a nuisance than a public health threat.


“There’ve been some diseases that have been isolated from the bed bugs,
but it’s not been shown, scientifically at least, that these are able to be
vectored by the bed bugs or transmitted from the bed bugs to a new
victim.”


Bed bugs are like tiny hitchhikers that can hide in your luggage and
clothing if you stay in an infested hotel room. Extensive cleaning and
insecticides are usually needed to get rid of a bed bug infestation.

That black mold you sometimes find in wet basements might cause
more trouble than you think. New research finds that toxins
produced by black mold are capable of killing cells that help us
smell. The GLRC’s Erin Toner reports:


Toxins found in the spores of black mold have been linked to
respiratory and neurological problems. But now, researchers at
Michigan State University have found that the toxins also affect
the nasal passages.


Veterinary Pathologist Jack Harkema was one of the researchers.
He says in the study, mice were given a small, single dose of black
mold toxin.


“When we examined these animals, we found that the cells that are
important to detect odors, or the sense of smell, that within 24
hours they died.”


Harkema says the toxins killed nearly 80 percent of nasal cells that
send signals to the brain. He says more research is needed to better
understand the effects of the toxin on people. That could be
important for thousands who’ve been affected by flooding,
including the disaster caused by Hurricane Katrina.

Study: Epa Ozone Standards Harmful

A new federal study finds ground level ozone in the air can cause lung
damage and lead to premature death at levels the Environmental
Protection Agency considers safe. The new study was funded by the
Centers for Disease Control and Prevention and the EPA itself. The
GLRC’s Rebecca Williams reports:


Ozone is the major ingredient of smog. Ground level ozone can make
asthma worse and can even cause permanent lung damage.


A new study in the journal Environmental Health Perspectives says the
EPA’s current standards aren’t good enough. The authors say breathing
ozone at levels the EPA considers safe can increase the risk of premature
death. The authors say if there is a safe level of ozone, it’s at very low
concentrations… far below current EPA standards.


But there’s a problem. Cities already have trouble meeting the current
EPA standards. The EPA says more than 100 million Americans live in
areas that exceed what the EPA considers safe.


The EPA is reviewing the scientific evidence on ozone to decide whether
to revise its standards further.

Michigan Puts Cap on Water Withdrawals

In the Great Lakes region, Michigan is the last state to pass laws that protect the Lakes from large-scale withdrawals. The GLRC’s Mark Brush has more:

Transcript

In the Great Lakes region, Michigan is the last state to pass laws to
protect the Lakes from large-scale withdrawals. The GLRC’s Mark
Brush has more:


More than twenty years ago, the eight Great Lakes states pledged to
protect the Great Lakes from large scale water diversions. But until now,
Michigan officials never put a cap on how much water could be
withdrawn.


Mike Shriberg is the director of the Public Interest Research Group in
Michigan – an environmental advocacy group. He says it was especially
important for Michigan to pass these laws since the state is nearly
surrounded by the Lakes:


“Michigan needed to establish a precedent here saying we’re taking care
of our own water that we’re actually setting limits on who can use our
water, before we really had good standing in any regional debates over
diverting Great Lakes water as a whole.”


The new laws say any new businesses planning large scale water
withdrawals will need to get permits from the state. The laws will allow
bottled water to be shipped out of the region in containers as big as 5.7
gallons.

Budget Cuts to Close Epa Libraries?

Transcript

An environmental watchdog group is criticizing President Bush’s
proposal to slash funding for the Environmental Protection
Agency’s library system. The GLRC’s Sarah Hulett reports:


The proposed budget would cut two million of the two-and-a-half
million dollars that pays for EPA’s libraries and reading rooms.


Internal EPA memos suggest the cuts could close EPA’s main
library and some of its regional libraries, and shut down the
system’s electronic catalog.


Jeff Ruch is with Public Employees for Environmental
Responsibility. He says the proposed cuts threaten an invaluable
resource the serves government scientists and the public.


“And so for reports on particular sites – like for example:
contaminated sites or Superfund sites – they’re the only place in
the world where you can get some of the detailed investigations
that have been done.”


An EPA spokeswoman says the agency plans to make its physical
collections more widely available online, but it’s not clear how the
agency will pay for digitizing the documents.

Composting in the City

  • Backyard composting isn't quite as inticing a hobby in the wintertime. (Photo by Karen Kelly)

Composting has always been a part of farm life, but a growing
number of city folks are trying it as well. The GLRC’s Karen
Kelly is one of those city dwellers, and she found if composting
isn’t convenient, it doesn’t get done:


“So we’re going to put in our banana peels, and the oatmeal that
nobody ate, and I’m going to break some of this up because apparently
it breaks down faster if it’s in smaller pieces. So right now we’ve got,
half a scone, a bowl of oatmeal, some banana peel… ”


It’s just after breakfast and my kitchen is covered with dirty dishes.
Some of the food is heading into the garbage, the rest I’m going
toss into the composter. It kind of looks like a brown garbage can
with a lid, but it takes about half my garbage and turns it back into
soil.


I started about a year ago, when I finally got a small backyard
where I live here in Ottawa, Canada’s capital city. First, I asked
my friends Connie and Dan how they do it.


“How would you guys describe your approach?”


“Laissez faire.”


“Yeah. It’s really a shame that everybody doesn’t do this because it can
be really easy. Just put it in a box and let it sit there.”


I liked the sound of that hands-off approach, but I was also
wondering what to put in and what I needed to leave out. So, I gave
George Reimer a call. He’s the city of Ottawa’s composting expert.


“ust stick with kitchen scraps, vegetables, fruit scraps…plants that
you have from the gardening season, that type of thing.”


“Okay, okay. So no animal products basically?”


“Exactly.”


Once you have a good mix of kitchen scraps, leaves and grass, the
best thing for compost is to mix it around on a regular basis. When
you add that oxygen to the microorganisms already in the garbage,
it breaks the waste down even faster.


It’s not as easy as it sounds – especially if you compost in a plastic
drum. Just imagine sticking a pitchfork into your garbage can and
trying to flip over a pile of wet dirt.


So, armed with that information, I asked George if he could take a
look at our progress after our first week of composting. He stooped
over to pull open a sliding door at the bottom of the container.


“Oh, you haven’t got anything in there, have you?”


“Well I did put some things in there…”


“Yeah, you need to put a slab down or dig it into the ground
because obviously something’s gone in there and removed it all.”


“Yeah, there’s no food in there. Okay. All right then. That was
a week’s worth of squirrel feeding.”


“Yeah exactly.”


(Sound of bricks laying)


So, the next day we go to a big box store to get some bricks. We
lay them all around the base of the composter. The squirrels are defeated.
A few weeks later, I see a huge raccoon shuffling across the backyard.
It knocks the top off the composter and climbs in.


We drive back to the big box store and buy some flat, heavy bricks
to lay on top of the lid. We also buy a few bags of fertilizer, of
course because we still have no compost. I think, this is starting to
feel like work and to be honest – I find it disgusting.


(Sound of brick noise)


“So now, it’s even more challenging to do this.”


(Sound of dumping)


“Ewww. A lot of it is sticking to the pot, which is disgusting but
alright. Uhh, brick back up, auxiliary bricks, okay.”


Now that I had to move those bricks, I was less likely to run out
with just the dinner scraps, and we weren’t mixing the compost very
often, either. So, I tried to remind myself of why I started doing this.


For one, it seemed like a shame to throw vegetable scraps into a
plastic bag and send them to a landfill. Especially when landfill
space is so tight that some Canadian cities are shipping their
garbage to the U.S.


Plus, we have a garden, which could use the nutrients from the
compost. According to George Reimer, those nutrients stick
around a lot longer than the ones found in commercial fertilizer.


I knew all that, and yet, on a stinking hot day in July – and the
composter was stinking because we rarely turned it – I officially
stopped. For a while… for six months. Until recently, when my
guilty conscience prodded me out the door with a bowl of kitchen
scraps.


(Sound of walking in snow)


“We’ve got snow on the ground and a bowl of fresh vegetable
scraps. Umm, interesting. It’s about a third full so there must be
compost under there somewhere.”


Last time I looked, the container had twice that amount in it.
Which makes me think that most of the food has broken down into
something we can finally use on the garden. It gives me an
incentive to start over. Plus, in a few years, I’ll have to compost.


Ottawa will join at least 18 other Canadian cities where residents
are required to throw food scraps into a separate container, and
hey, if all else fails, there’s nothing like a new law to get you
motivated.

Invasive Species at the Aquarium

Big, public aquariums spend a lot of money to make fish look like
they’re at home in the wild, but lately some aquariums are showing fish
that are out of place. The GLRC’s Shawn Allee looks at one aquarium’s
effort to give them the spotlight, too:


The federal government’s spending millions to keep Asian Carp out of
the Great Lakes. Biologists worry Asian Carp could devastate the lakes’
ecosystem. Recently, though, several carp were brought within sight of
the Great Lakes, and biologists are happy about it.


Chicago’s Shedd Aquarium is on the shore of Lake Michigan. It’s
holding an exhibit of Asian Carp and other alien invasive species.


Curator Kurt Hettinger captured the aquarium’s carp during a trip on an
Illinois river.


“They’re literally jumping, sometimes over the bow of the boat,
sometimes smacking into the side of the boat. I just looked behind me
and was amazed to see all these fish jumping in the wake of the boat, and
to this day, I’m still stunned by this.”


And Hettinger’s more than just stunned. He’s worried.


Asian Carp are an invasive species, basically … pests that crowd out
native fish, and that river where he caught them hooks up to Lake
Michigan.


Again, Asian carp haven’t made it to the Great Lakes, but more than one
hundred and sixty other invasive species have arrived and are breeding
quickly.


One example’s the zebra mussel. At first, scientists worried about how
much money it could cost us. Zebra mussels multiply so fast they can
block pipes that carry cooling water to power plants. But now, we know
the zebra mussel’s disrupting the lakes’ natural food chain.


In other words, invasive species are a huge economic and ecological
nuisance. That’s why the Shedd Aquarium started the exhibit.


“The public I think has seen enough stories about the damages and the
spread and the harmfulness, but those stories are not very often coupled
with solutions.”


That’s ecologist David Lodge. He says the exhibit tries to show how
people spread these species around. Lodge points to one exhibit tank. It
looks like a typical backyard water garden. It’s decked out with a small
fishpond, water lilies, even a little fountain shaped like an angel. It looks
pretty innocent, but Lodge says plants and fish you buy for your own
water garden could be invasive species.


“All those plants and animals that are put outside, then have an
opportunity to spread. Now, it doesn’t happen very often, but with the
number of water gardens, it happens enough so that they are a serious
threat to the spread of species.”


Birds or even a quick flood could move seeds or minnows from your
garden to a nearby lake or river.


The Shedd Aquarium’s not alone in spotlighting invasive species.
Several aquariums and science museums are also getting on board. For example one in
Florida shows how invasive species have infested the Everglades.


Shedd curator George Parsons went far and wide for inspiration.


“I was in Japan last year when we were planning this, and I just
happened to stumble across one of their aquariums and they had an
invasive species exhibit, except that they were talking about large mouth
bass and blue gill. You know, something that is our natives. So, it was
kind of ironic to see that out there. It was kind of neat.”


Like us, the Japanese take invasive species seriously. Back in 1999 the
humble Midwestern Blue Gill created a national uproar. Turns out, they
had taken over ponds throughout the Emperor’s palace, and how did the
bluegill get to Japan?


Probably as a gift from a former Chicago mayor. Apparently, the mayor
thought blue gill might make nice sport fishing in Japan. It was an
innocent mistake, but it’s just the kind of mishap biologists want all of us
to avoid from now on.
