Lawn pesticides are killing a lot more than grubs and weeds, according to the National Audubon
Society. They want to let people know that if they use the chemicals, they are unintentionally
killing birds. And they’re possibly putting their families at the same risk. For the Great Lakes
Radio Consortium, Joyce Kryszak has more on the educational campaign:
People throughout the region have been scooping up dead bird corpses and sending them off for
testing since the West Nile Virus first hit. But research shows West Nile is usually not to blame.
Studies done on about eighty thousand dead birds found in New York state showed aesthetic
lawn care products were the leading killers.
William Cooke is a regional coordinator for the Audubon Society. He says the toxins from these
common product rivals the chemicals used on golf courses and farms.
“We’re going to have our kids play on this, we’re going to have the dog play on this, and then come
into the house? People are not connecting between the pesticides they put down and the impacts.
And we’re doing this for a green lawn?”
Cooke says the national educational campaign hopes to alert more than a million people to the
dangers of pesticide use. It will also tell people how to find and use organic alternatives to
maintain a healthy lawn and environment.

An insect called the Emerald Ash Borer has already destroyed thousands of ash trees in Ontario
and Michigan…and in February, it was discovered invading the northwest corner of Ohio.
Agriculture officials there are trying to contain the bug before it spreads to still more states.
The Great Lakes Radio Consortium’s Bill Cohen reports:
At stake across the Great Lakes region: millions of dollars of wood that’s used for furniture,
cabinets, flooring, and baseball bats. That’s why Ohio agriculture officials have quarantined an
area around Toledo, banning residents from transporting ash wood out of the area. They’ve also
sprayed pesticide on nearby un-infected trees and taken even more drastic action among the 4,000
trees the beetles had already struck.
David Shlike works for the Ohio Agriculture Department.
“At ground zero, out a quarter of a mile, we cut everything, took it down. And had to chip it. We
hauled these chips to Michigan, and they were incinerated. It’s just a devastating pest and that
pest is going to be hatching out here anytime now between the 1st of May and the 15th of May,
and we were trying to take away its food source.”
It will be a few more months before it’s clear whether or not Ohio’s action has stopped the bugs’
advance.

The U.S. Fish and Wildlife Service is proposing a rule that would allow
people to kill the double-crested Cormorant. The bird was once federally
protected. The Great Lakes Radio Consortium’s Chris McCarus reports:
The double-crested Cormorants have become a nuisance because they eat a
lot of fish and their waste destroys trees and grass. The U.S. Fish and
Wildlife Service wants tribes and conservation officials to identify Cormorants that pose a problem. They would shoot the birds with shotguns or destroy their
nests and eggs. Commercial fish farmers would also have the right to destroy
the birds.
Ray Rustem is with the Michigan Department of Natural Resources. He
says wildlife officials will need a coordinated effort to be successful.
“Well, these are very intelligent birds and hunting is going to be a lot more
difficult because they will learn very quickly if there is a boat around they are going to get shot at
and they’re going to avoid those kind of things.”
In the ’70’s, the pesticide DDT had killed most of the double-crested Cormorants in the Great
Lakes region. They’ve since recovered and now number about 1 million.
The federal government is accepting comment on its proposal to kill these birds.

Genetically modified crops are planted throughout the Midwest, but some scientists are concerned genes from these crops could escape and work their way into weedy plants. With these genes, weeds could become more vigorous and harder to kill. New research shows this can happen between closely related crops and weeds.

Genetically modified crops are planted throughout the Midwest, but some scientists are
concerned genes from these crops could escape and work their way into weedy plants. With
these genes, weeds could become more vigorous and harder to kill. New research shows this can
happen between closely related crops and weeds. The Great Lakes Radio Consortium’s Cristina
Rumbaitis-del Rio prepared this report:
Genetically modified crops have been around for quite a while. In the U.S. last year more than 88
million acres were planted with genetically modified soybean, corn, cotton and other crops. Some
of these plants are engineered to be more resistant to herbicides, making it easier for farmers to
get rid of weeds without damaging their crop. Others are engineered to resist plant-eating insects.
But some scientists worry about the ecological effects of these crops. Allison Snow is a professor
of ecology at Ohio State University. She studies genetically modified sunflowers. Snow says she
got involved in this research when genetically modified crops were first being introduced because
she was afraid no one else was looking at the environmental effects of these crops.
“It was kind out of a fear factor for me of wanting to make sure that someone was watching to see
what the environmental effects might be.”
The sunflowers Snow studies have a gene added to them, which produces an organic insecticide
that kills insects feeding on the plants.
According to Snow, the problem with these pesticide-producing sunflowers is the insect-killing
gene can be transferred from crop sunflowers to their weedy cousins, which are often growing on
the edges of fields. Bees, flies and other insects can transfer the gene to the weeds by cross-
pollinating the plants, which are close relatives. Snow’s research shows once the gene gets into
the weed population, the weeds become insect-resistant as well.
“The new gene worked really, really well in the weeds. It protected them from the insects. And
because they were protected, they had more energy to devote to making seeds.”
Snow says the most startling result was the number of seeds these weeds were making.
“In one of our study sites, they made 55% percent more seeds per plant – just because of one
gene. Which is kind of unheard of. We’ve never seen a result like that – where one gene would
cause the whole population to suddenly start making 55% more seeds.”
The gene might make weeding a more difficult task, but Snow says she wouldn’t quite call them
“super weeds,” a term some environmentalists have used.
“We might see that the weedy sunflowers become worse weeds, I wouldn’t call them super
weeds, because to me that would imply that they have many different features instead of just one
that causes them to make more seeds. But I could imagine in the future there might be enough
traits out there that could turn a regular weed into something much more difficult to control – like
really would be a super weed.”
Snow says she will have to do more research to see if the extra seeds made by the weeds will turn
into more weeds and hardier weeds in farmer’s fields.
But, she might not be able to finish her research on sunflowers because the companies that make
the crop have decided not to renew her funding and won’t give her access to the sunflowers or the
genes.
“It was all about stewardship and responsibility.”
Doyle Karr is a spokesperson for pioneer hi bred, one of the companies which makes the
sunflowers. He says the company realized a few years ago there wasn’t enough demand for the
product to justify commercially producing it. As a result, he says, the company couldn’t continue
funding sunflower research, and doesn’t want to be held responsible for keeping the gene safe
while the research is being conducted.
It’s an issue of a biotech trait that we are not pursuing and not bringing to the market, and if we’re
not bringing it to the market, we can’t justify taking the responsibility of having that trait out
being worked with, with a third party.”
While some academic researchers argue the universities take on legal liability when they work
with genetically modified plants, Karr says the university’s liability is often limited by state law.
He says the company is ultimately held responsible if only by the court of public opinion.
“Should something happen with this gene that was not expected or a mistake happened – that
would ultimately come back to those who initially made the gene available.”
While this issue remains unresolved, Snow is continuing her research. Genetically modified
sunflowers are not the only crop to study. Snow is now working in Vietnam where weedy species
of rice grow naturally, and where genetically modified rice might be introduced in coming years.
She’s concerned the traits of the genetically altered rice might be transferred to the wild species
of rice, just as happened with the sunflowers.

Corn growers in Michigan and Minnesota are waiting to find out whether they can use a new herbicide this spring. “Balance Pro” is used in 17 states, including several in the Great Lakes region (Indiana, Illinois, Ohio). But it’s not used in Minnesota, Michigan, or Wisconsin. Critics say Balance Pro gets into rivers and lakes too easily, and it could harm wildlife or even people.

Balance Pro gets into rivers and lakes too easily, and it could harm wildlife or even people. The
Great Lakes Radio Consortium’s Stephanie Hemphill reports:
Four years ago, the U.S. Environmental Protection Agency gave conditional approval for a new
weed-killer called Balance Pro. It’s made by a division of Bayer, the same company that makes
aspirin. But the EPA still had some worries.
EPA researchers thought the ingredients in Balance might accumulate in irrigation water. Some
people say, if it turns up in irrigation water, it could turn up in drinking water.
“Missouri has had drinking water reservoirs contaminated with this, and contaminated within the
first year of its use.”
Jannette Brimmer is with Minnesota Citizens for Environmental Advocacy. She worries that
Balance could turn into another environmental problem like atrazine. Atrazine is a commonly
used herbicide. It shows up in drinking water in many parts of the country, at very low levels.
Some studies show, even at those low levels, it’s causing deformities in the sexual organs of
frogs, which might be responsible for reductions in frog populations. And Brimmer wonders if
it might be affecting people too.
“In other words, small dosages at the wrong time in fetal development, pregnancy, in a kid, can
have significant impacts. So we have an opportunity to do the right thing before it gets into our
water, before it poses a health threat, before it’s a problem.”
The EPA doesn’t do any tests to find out whether herbicides affect the hormones of frogs or
people. The agency did conduct tests on the reproduction rates of aquatic animals, and found no
effects.
But the EPA does have one major concern — the effect Balance might have on other crops.
Officials worry if farmers use water polluted with Balance to irrigate crops like cabbage or
lettuce, the herbicide could hurt crop yields.
Both Michigan and Minnesota are trying to figure out how big a threat that might be. Dan
Stoddard, at the Minnesota Department of Agriculture, has been watching the field studies from
other states. He says the results are mixed.
Some of the studies looked at how much Balance got into water supplies. They found lower
concentrations than scientists originally predicted.
But some regions are more vulnerable than others, depending on the type of soil. Dan Stoddard
says areas with coarse or sandy soil, or shallow bedrock, are especially vulnerable.
“What has been considered is some requirements that would restrict use of the product in those
areas. But nonetheless it does have the potential to get into groundwater. What we would
require is additional monitoring to see whether that is in fact happening.”
Stoddard says he’s weighing the risk of polluted water against the benefits Balance might offer.
He’s hearing from companies that have been applying Balance in other states. They say, by
adding the new product to their arsenal, they can cut down on their use of other herbicides.
“If somebody uses the same type of pesticide or herbicide over a few years, weeds can become
resistant and what they wind up having to do is increase the concentration of that product. So
having a new chemistry allows lower application rates of the product.”
Wisconsin recently approved the use of Balance. But the Wisconsin Agriculture Department
there imposed so many restrictions, the company decided not to market it in the state. Bob
Olson is a farmer, active in the Wisconsin Corn Growers Association. He says his state is
putting him at a disadvantage compared to other farmers.
“It’s been registered in 17 other corn states. It’s just not been able to be registered here in
Wisconsin because of what we think are undue concerns. And the fact that we can find it in
increasingly smaller quantities. Simply because you can find something, doesn’t mean that level
is ever going to affect anyone.”
Michigan and Minnesota are planning to decide in time for spring planting whether to let
farmers use Balance in their states.

Scientists are working to control a new non-native beetle that’s destroying hundreds of
thousands of ash trees in the Great Lakes region. The Great Lakes Radio Consortium’s
Erin Toner reports:
The Emerald Ash Borer is native to Asia, and probably made its way to the United States
through wood packing materials. Therese Poland is an entomologist with the
USDA. She says so far, the beetles have destroyed 100 thousand ash trees in southeastern
Michigan and southern Ontario.
“We think it’s been here for at least five years and even with some of the other exotic
beetles that have been discovered in recent years, when they were first discovered they
weren’t as widespread as this.”
Poland says there’s a quarantine over the infested areas to keep the beetles from moving
to new areas. Officials are inspecting nurseries to make sure they’re not selling infested
trees. They’re also checking whether tree care companies are disposing of trees properly.
But officials admit they probably won’t be able to stop people who unknowingly transport
infested firewood or yard waste.

Thirty years ago, peregrine falcons were nearly extinct in the Midwest. Today, environmental protection efforts have succeeded in returning the fast-flying raptors to their earlier numbers… and even better. The Great Lakes Radio Consortium’s Diane Richard has more:
A twenty-year program to restore peregrine falcons is seeing new signs of
success this summer: hatchlings.
Experts estimate that as many as 300 peregrine falcons will hatch this year.
In the sixties, DDT all but wiped out the population. But the peregrine
falcon is back, thanks to a ban on the pesticide and conservation efforts by the Midwest Peregrine Falcon Restoration Program.
Since the eighties, this regional partnership has released birds bred in captivity. Today, it’s monitoring peregrine falcons at 30 sites across 13 U.S. states and two Canadian provinces.
Mark Martell is a conservation coordinator with the restoration program. He
says the challenge now is to keep the population thriving.
“We don’t have a lot of experience with taking a species from zero
individuals up to a stable population. So we want to make sure this
population stays stable.”
To do so, Martell says researchers will spend the next 20 years keeping tabs
on the falcons and their chicks.

The worldwide population decline in frogs and other amphibians has concerned
scientists for many years, in part because when amphibians are threatened, other
species are as well. A current study provides new insights into the factors that can
make frogs more susceptible to disease. The Great Lakes Radio Consortium’s Cindi
Deutschman-Ruiz reports:
New research conducted by Penn State Ecologist Joseph Wiesecker indicates that
frogs face a much higher risk of developing severe limb deformities when exposed to
currently acceptable levels of two common farm chemicals… the weedkiller atrazine
and the insecticide malathion.
These chemicals lowered the immune response of frogs, which is why they became
more susceptible to disease. Wiesecker says understanding this susceptibility is key
to safeguarding not only amphibians but humans as well.
“The apparent increase in limb deformities over the last decade is part of a larger
issue, one that involves amphibians but also humans and other animals. And that is
the increase or prevalence of infectious disease.”
Wiesecker is now conducting a five-year regional study that will artificially create
environmental changes associated with human development, and chart their impact
on frogs and other wetland animals.

While the U.S. continues to struggle over the use of pesticides, its neighbor to the north has recently taken some major steps toward restricting its use. Earlier this year, Canada’s largest grocery chain announced that its 440 garden centers would be pesticide-free by 2003. In the wake of this announcement, the Canadian government introduced amendments to its 33 year-old pesticide control act. Great Lakes Radio Consortium commentator Suzanne Elston says that while this is welcome news, “What took so long?”
Contrary to popular belief, there are at least three things that you can’t avoid – death, taxes and pesticides. Pesticides are everywhere – in our food, in our water and in the air that we breathe.
Ever since the publication of Rachel Carson’s book, Silent Spring, 40 years ago, many environmentalists have expressed their concern that anything that can kill other living organisms must also have an effect on human health. They have patiently gathered evidence while encouraging the scientific community to do the same. But despite our growing awareness of the dangers of pesticides, progress toward restricting their use has been painstakingly slow.
And then came Hudson. A decade ago this small Quebec town passed a local by-law to restrict the cosmetic use of pesticides. Cosmetic use generally means using them to improve the appearance of lawns and gardens. Two lawn care companies immediately took the town to court. The ensuing legal battle dragged on for ten years. But the town’s remarkable tenacity paid off. Last year the Supreme Court of Canada unanimously upheld Hudson’s right to legislate the use of pesticides and encouraged other municipalities to do the same.
The Supreme Court decision literally opened a floodgate of activity. Hundreds of municipalities that had been waiting for the Hudson ruling are now proceeding with their own pesticide legislation.
Even the traditionally conservative Canadian Cancer Society – known for its “cancer can be beaten” philosophy is calling for a ban on the cosmetic use of pesticides known to cause cancer. Apparently, cancer not only can be beaten – it can be prevented.
Then in March a modern day corporate miracle happened. The Loblaw’s grocery chain announced that it would be pesticide free in all of its 440 garden centers by next year. What was so amazing about the giant retailer’s announcement is that a cancer victim inspired it. After being diagnosed with breast cancer in 1997, a young Canadian doctor went on a one-woman campaign to ban pesticide use. Dr. Bruinsma’s story caught the attention of a Loblaw’s company official and the rest is corporate history.
It was only after all of this, that the Canadian government finally introduced a long promised update of its 33 year-old pesticide act. While the bill isn’t perfect, it is a step in the right direction – the direction that environmentalists have been pointing to for decades.
The Canadian Cancer Society, Loblaws, even the Canadian government are making some dramatic shifts in direction thanks to the extraordinary efforts of ordinary citizens – many of them cancer patients, like Dr. Bruinsma. While struggling with their own disease they have gathered evidence about the harmful effects of pesticides in the hopes of preventing others from suffering the same fate.
Sadly, Dr. Bruinsma didn’t live to see the change in Loblaw’s corporate policy. She died of breast cancer just a few short weeks before the announcement was made. Ironically, Rachel Carson, the great-grandmother of the anti-pesticide movement also lost her life to breast cancer a few years after Silent Spring was published in 1962. What we can learn from their deaths – and their remarkable lives – is that change, as always, starts with the power of one.
Pesticides are designed to kill pests – and so – by their nature are toxic substances. They wouldn’t work otherwise. While that poisonous nature is useful for certain jobs… most people would probably hesitate before knowingly taking the chemicals into their bodies. But the Environmental Protection Agency is now looking at the issue of testing pesticides on humans. As bad as that may sound, the Great Lakes Radio Consortium’s Greg Dahlmann reports there are some people saying it’s what we need:
