Modified Crops Swap Genes With 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.

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.

Canada to Join in Seaway Expansion Study?

The U.S. Army Corps of Engineers wants funding to continue a study of expanding the St. Lawrence Seaway for bigger ships. Now amidst widespread speculation, a Canadian environmental group doubts Canada will support it. The Great Lakes Radio Consortium’s David Sommerstein reports:

The U.S. Army Corps of Engineers wants funding to continue a study of expanding the St.
Lawrence Seaway for bigger ships. Now amidst widespread speculation, a Canadian
environmental group doubts Canada will support it. The Great Lakes Radio Consoritum’s David
Sommerstein reports:

Canada’s role is critical to the study moving forward. In many places, the Seaway channel is in
Canadian waters and Canada owns most of the Seaway’s locks. Mary Muter is with the Georgian
Bay Association, an Ontario-based environmental group. She says Canada’s Transport Minister
David Collinette will not help pay for the study unless it beefs up its environmental approach.

“We have heard from Minister Collinette that he is only interested in funding a joint study with
the U.S. transport department that will look at the environmental impacts and that the full
scenario is looked at.”

Others say Canada will sign on. Keith Robson of the Hamilton Port Authority believes Transport
Minister Collinette is dedicated to expansion.

“My impression is that Collinette understands very much the benefits of marine transportation.”

Collinette himself has declined to comment. Transport Canada says talks with the U.S. are
ongoing.

Congress to Approve Seaway Expansion Study?

Congress is considering spending up to 2-million dollars for a long-term study of widening and deepening the Saint Lawrence Seaway. Opponents say an expansion of the Seaway will only mean more environmental trouble for the Great Lakes. The Great Lakes Radio Consortium’s Mike Simonson reports:

Congress is considering spending up to 2-million dollars for a long-term study of widening and
deepening the Saint Lawrence Seaway. Opponents say an expansion of the Seaway will only
mean more environmental trouble for the Great Lakes. The Great Lakes Radio Consortium’s
Mike Simonson reports:

The bone of contention is a multi-year study that looks at allowing larger ocean-going ships to get
through the Seaway. The Seaway links the Great Lakes to the Atlantic Ocean. The National
Wildlife Federation’s Rick Spencer in Washington says that would rip up the Saint Lawrence
River and stir up pollution from Montreal to Milwaukee.

“Dredging hundreds of millions of cubic yard. Blasting islands. You are destroying fish habitat,
you’re going to be releasing toxic sediments. You’re going to increase the risk of new invasive
species.”

Right now channels are 25 feet deep. The study will look at digging 10 feet deeper, allowing
ships to take on more cargo at less cost. Duluth Port Director Davis Helberg says the protests are
exaggerated.

“We’re talking about a study. We’re talking about an analysis that will focus on engineering,
economics, and on the environmental aspects of keeping the Seaway competitive in the long
term.”

The proposal is in the House and Senate conference committee and will be decided later this
month.

Feds Take Utility Company to Court

The U.S. Justice Department is suing several utility companies in the Midwest and South. The charge is that they didn’t install state of the art pollution controls when they renovated their power plants, a violation of the federal Clean Air Act. The first case is being heard in a federal courtroom in Columbus, Ohio. The Great Lakes Radio Consortium’s Bill Cohen reports:

The U.S. Justice Department is suing several utility companies in the Midwest and South. The
charge is that they didn’t install state of the art pollution controls when they renovated their power
plants, a violation of the federal Clean Air Act. The first case is being heard in a federal
courtroom in Columbus, Ohio. The Great Lakes Radio Consortium’s Bill Cohen reports:

About a decade ago, First Energy corporation fixed up a power plant built in 1959 in
Steubenville, Ohio, but it didn’t put in the latest high-tech scrubbers. The company insisted it was
just routine maintenance, so the requirement for top of the line pollution controls didn’t apply.
The justice department disagreed and sued, and states in the Northeast are cheering. They say
soot and smog from the Great Lakes region travel hundreds of miles to New England.
Environmental activists like Jack Shaner say maybe the pollution travels, maybe it doesn’t, but
either way, a crackdown is needed.

“Study after study have shown it’s the folks that live in the shadow of these power plants within a
hundred miles or so that bear the brunt of it. That’s why it’s particularly important for Ohio and
for the Midwest to clean up these power plants. If it helps New England, God bless ’em, but we
gotta start in our own backyard here first.”

President Bush is reportedly pushing for changes, so that state of the art pollution controls
couldn’t be required so often.

Carbon Dioxide Injection to Reduce Pollution?

Scientists are talking about a new way to address global warming. Their idea is to take carbon dioxide from coal-burning power plants and inject it deep into the earth. The Great Lakes Radio Consortium’s Annie MacDowell explains:

Scientists are talking about a new way to address global warming. Their idea is to take carbon
dioxide from coal-burning power plants and inject it deep into the earth. The Great Lakes Radio
Consortium’s Annie Macdowell explains:

It’s called carbon sequestration. The idea is to use a chemical process to remove carbon dioxide
from power plant emissions and pressurize it into a liquid form. The liquid would then be injected
into saline aquifers up to ten thousand feet below the ground.

The government wants to create 4 to 10 regional partnerships to study the possibility of carbon
sequestration. One of the potential sites is in the Illinois Basin. The basin extends throughout three
quarters of Illinois, into Western Indiana and Western Kentucky.

Robert Finley is the director of the Center for Energy and Earth Resources at the Illinois State
Geological Survey. He says carbon sequestration could be a good transition for the country as it
moves away from using fossil fuels.

“It would allow us to use coal in a more environmentally responsible way while we look toward the
future with additional use of renewables and ultimately, perhaps, going to a hydrogen economy.”

Finley says at this point, sequestration doesn’t work with other pollutants found in power plant
emissions, such as sulfur dioxide, nitrogen oxide, and mercury.

Region’s New Governors Face Challenges

New governors from different political parties than their predecessors took over in more than half of the states around the Great Lakes.

New governors from different political parties than their predecessors took over in more than half
of the states around the Great Lakes. In most of those states, the governors’ seat went from
Republican to Democrat. Some environmental groups are optimistic that the changes will benefit
their causes. But the Great Lakes Radio Consortium’s Lester Graham spoke with journalists
around the region who feel politics and state budget problems will slow any change the new
governors might want:

Five of the eight Great Lakes states have new governors. Four of those states went from
governorships long-held by Republicans to a Democrat governor.

For example, Republicans held the Illinois govenor’s seat for 26 years. That changed when
Democrat Rod Blagojevich took the office. The environment was not a huge issue in the
campaign. Under the Republicans there’s been an interest in acquiring large pieces of land for
parks and creating green corridors. And Blagojevich is even retaining the previous
administration’s director of the state Environmental Protection Agency. Still, some
environmentalists feel they’ll fare better under a Democrat.

At the Illinois capitol, Bill Wheelhouse is the Statehouse Bureau Chief for Illinois Public Radio.
He says the change probably won’t be that significant…

“Environmental groups will see more friendly territory for some of their pet projects to some
degree. But, Illinois is not a liberal state. It’s not one that is concerned with ground-breaking
legislation on the environment or anything else. Politics is a business in that state and that can
never be forgotten.”

Despite that, the new governor, Blagojevich, has outlined a couple of areas he’d like to change.
One is charging businesses for pollution discharge permits, something that’s been free in the past.
It’s popular among lawmakers because it brings in more money for the state which is facing
budget deficits. Bill Wheelhouse says another issue Blagojevich has proposed is legislation
mandating that Illinois power companies use renewable resources such as wind and solar power.

“What it would do is in just a couple of years require that part of the energy portfolio of a utility
company include five percent renewable energy and that would increase, I believe, up to about
15-percent a decade down the road.”

Again, that kind of legislation wouldn’t cost the state any new money. That’s a plus.
Wheelhouse adds that even with Blagojevich’s fellow Democrats controlling both the House and
the Senate, any environmental proposal that doesn’t pay for itself is not likely to get very far,
because of Illinois’ budget deficit.

It’s the same story in other states. Illinois’ neighbor to the north, Wisconsin, also saw a shift
from several years under Republican governors to a newly installed Democrat. Jim Doyle is now
Governor.

Reporter Chuck Quirmbach covers environmental issues for Wisconsin Public Radio. He says
the race for governor touched on the environment, but there was another more immediate issue to
consider.

“The overwhelming issue, the issue common to a lot of states is the state budget deficit here in
Wisconsin, but the environment was an important difference. It energized a lot of environmental
groups to vote for Doyle or this Green Party candidate who got about two-percent of the vote. So,
it was a significant difference. It may not have been the number one issue in the state, though.”

Quirmbach says while environmentalists are optimistic about a Democrat taking the governor’s
office, Governor Doyle will have to compromise with the Republicans who hold a majority in
both chambers of the Wisconsin legislature… and he’ll have to make compromises because of the
state’s budget…

“The threat to the green agenda will be the economy and whether Doyle decides, ‘Well, putting
people to work might be more important than protecting certain wetlands or protecting the
environment from air pollution.'”

Across Lake Michigan from Wisconsin is another state that’s long had a Republican governor.
Michigan elected Democrat Jennifer Granholm, and in Michigan, the environment was a key issue
in the campaign for governor.

Sarah Hulett covers state government for Michigan Public Radio Network. She says the
Democrat governor quickly moved on an environmental issue which gets some Republican
support in Michigan.

“Right when the governor came in, Governor Granholm, she put together a land-use commission
— Smart Growth Commission, I think, is the name of it — made up of Democrats and Republicans
and involved the Republican leaders in both chambers in that. So, she’s off to a pretty good start
in terms of the environment, I’d say.”

But, like Wisconsin and Illinois, Michigan is facing budget problems and Hulett says the new
Democrat governor might find the environmental initiatives that cost the state will be a hard
sell to the Republican-held legislature.

“Well, the deficit is huge. And, so, that affects everything across the board. And, you know, the
environmental community is having to be patient with some of these initiatives.”

It’s a similar story in Pennsylvania where Democrat Ed Rendell took the governor’s seat from
Republicans. Rendell is friendly to environmental issues, but he, too, has to deal with a budget
deficit and he has to work with a Republican-controlled legislature.

So, despite conventional wisdom which indicates more enviro-friendly laws might come from a
Democrat in the Governor’s mansion, in those states where there’s been a change, the economy
might force those governors to put the environment further down on the list of priorities.

For the Great Lakes Radio Consortium, this is Lester Graham.

REGION’S NEW GOVERNORS FACE CHALLENGES (Short Version)

Half of the states surrounding the Great Lakes have seen the governor’s office switch from
Republican to Democrat. Environmental organizations believe that will be good for their causes.
But the Great Lakes Radio Consortium’s Lester Graham reports other factors might interfere:

Conventional wisdom finds that Democrats are more often friendly to environmental issues than
Republicans. Of course that’s not always true, but when four Democrats seized four
governorships that had been long-held by Republicans, many environmentalists were optimistic
they’d get a better deal. That optimism might be short-lived. Now that the Democrat governors
in Illinois, Wisconsin, Michigan and Pennsylvania have had time to look at the budget, the reality
of politics is setting in and in most cases the environment isn’t quite as high on the list of
priorities. Each of the states is facing budget shortfalls, some amounting to a couple of billion
dollars. And in three of those states the Democrat governor will have to work with a legislature
controlled by Republicans. Political observers say it’s clear that the new governors will have to
find compromises in any environmental initiatives they talked up during the campaigns.

Virgin Shark Birth Sets Researchers in Motion

A female shark in an aquarium in the Great Lakes region has apparently given virgin birth. Four shark eggs hatched last year and three of those babies are now growing normally.

A female shark in an aquarium in the Great Lakes region has apparently given virgin birth. Four
shark eggs hatched last year and three of those babies are now growing normally. As the Great
Lakes Radio Consortium’s Celeste Headlee reports, it may be some time before the cause can be
determined, but the event is still a surprise for biologists:

Biologists have a technical term for virgin birth. It’s called parthenogenesis. Doug Sweet is the
Curator of Fishes at the Belle Isle Aquarium in Detroit. He says parthenogenesis is common in
invertebrates and some amphibians.

“Most vertebrate animals, the females will produce eggs even if the male is not around. And it’s
just a matter of… it’s a chemical trick, basically, to get that egg to develop into an individual
without a sperm activating it.”

But parthenogenesis has been totally unheard of for sharks, until now. Last year, the Henry
Doorly Zoo in Omaha, Nebraska, announced they thought a Bonnethead shark there had
reproduced by parthenogenesis. The baby lived less than 12 hours, though, and genetic tests were
inconclusive.

But when Doug Sweet saw the press release from the Henry Doorly Zoo about a possible virgin
birth, he thought he’d try an experiment. Sweet decided to incubate the eggs of his two female
bamboo sharks. Four of the eggs developed. Sweet says the sharks were acquired by the
aquarium before they had reached sexual maturity, and they have never been exposed to a male.
He says the likely conclusion is that these sharks are reproducing by parthenogenesis.

Two other explanations, though highly unlikely, are that the shark has both testicular and ovarian
tissue, and fertilized its own eggs or that sharks are capable of storing sperm for years and even
passing it down to their offspring. Sweet has sent small clippings from the sharks’ fins to the
Henry Doorly Genetics Lab. Testing has already begun, but Sweet says it could take more than a
year to get the results. In the meantime, Sweet says the facts remain the same: a female shark
has given virgin birth. If it is parthenogenesis, he says, it will have important implications for
biologists around the world.

“Parthenogenesis just hasn’t been considered to happen in sharks; it’s never been recorded. It may
be happening all the time out there, so this is kind of breaking news in the shark world.”

The two adult bamboo sharks and the offspring are currently on exhibit at the Belle Isle
Aquarium in Detroit.

Report Says Water Worries Overstated

The international commission that keeps an eye on the environmental health of the Great Lakes
will hold public hearings later this month on a report that looks at water use in the basin. And as
the Great Lakes Radio Consortium’s Sarah Hulett reports, the findings are not pleasing
environmentalists:

The International Joint Commission asked a team of experts to examine water issues including
use and diversion, climate change, and conservation. The report says the problem of water
overuse in the Great Lakes has been overstated in the past three decades, while conservation has
been underestimated. It also calls the prospect of diverting water to arid southwest states “a dead
issue.”

Cameron Davis is with the Lake Michigan Federation. He says the report fails to recognize the
issues that will face the Great Lakes in the long term.

“One of the concerns that I have is that, in saying we’re not using that much water, that the
hidden message is don’t worry. We don’t have a problem.”

But the U.S. chair of the IJC, Dennis Schornack, says recognizing the pitfalls of faulty
projections is important to shaping future water policy.

The Commission will hear public comment on the report before drafting its own plan to present
to the governments of Canada and the U.S.

Making Electricity From Grass

Low prices for corn and soybeans have led many Midwest farmers to look for a new crop to mix with their usual rotation. Some are turning to plants grown specifically for what’s called “biomass.” Biomass crops can be used as fuel.

Low prices for corn and soybeans have led many Midwest farmers to look for a new crop to mix
with their usual rotation. Some are turning to plants grown specifically for what’s called
“biomass.” Biomass crops can be used as fuel. While research on biomass is in its infancy… one
particular crop has caught the eye of researchers who say it would be perfect for Midwest power
plants. The Great Lakes Radio Consortium Shawn Johnson reports:

In a farm field not too far from the University of Illinois stands a small plot of miscanthus. The
wavy, 12-foot tall grass topped with fluffy, seedless flowers is native to some places in Europe,
where it’s catching on as a crop to burn. Researcher john clifton-brown of Trinity College in
Dublin, Ireland has grown miscanthus on his father’s farm for 12 years now. He says it’s a
natural fit for Illinois.

“You seem to have in Illinois superb soil. You seem to have very low corn prices. You have
rainfall. And these factors combined look like a golden opportunity for the development of
renewable energy from biomass crops like miscanthus.”

Miscanthus is giant grass that can be planted in the same fields that normally grow corn and
soybeans. The similarities pretty well stop there. Where most Midwest farmers are used to
growing crops that produce food, miscanthus is grown specifically to be chopped off, bailed, and
burned, usually with coal in coal-fired power plants.

John Caveny owns the land where this miscanthus plot is growing. He stops short of calling this
a new way of farming:

“Well, in way it is, in a way it isn’t. What all farmers do, when you get right down to it, is
advance the value of sunlight energy. That’s what you do, whether you grow tomatoes, whether
you grow flowers, whether you grow grass, whether you grow corn.”

In the case of growing miscanthus, the process is much different than that of most Midwest crops.
Farmers use multi-row planters pulled behind tractors to plant corn and soybeans. To grow
miscanthus, a producer needs to dig holes and plant sprigs of the grass one at a time to be
successful. The crop will grow back on its own year after year for up to 30 years, but it’s not big
enough to be harvested the first few years its in the ground. Even with all these complications,
University of Illinois researcher Steve Long says a farmer who’s willing to make an investment in
miscanthus can reap great rewards in the long run.

“You do need labor to put this into the ground, but then after that, this is considerably less labor
than corn or soybeans, and on current figures, it is more profitable.”

Those figures are more theory than reality at this point, because a market for miscanthus has yet
to emerge. Dynegy is the only power company that buys miscanthus in this part of Illinois. And
even dynegy won’t be ready to harvest biomass crops on a large scale for another five years. But
the energy company projects it could eventually pay 40 dollars per ton of dried… harvested
miscanthus. That’s pretty good money for the farmers. The reason dynegy will pay that much?
While it doesn’t burn as efficiently as coal… miscanthus emits far fewer pollutants. And while it
emits greenhouse gases such as CO-2 while it’s burning, it will recapture those gases when it
grows. As energy companies are forced to meet more and more environmental requirements,
Dynegy’s Chris Williams says miscanthus becomes appealing:

“It’s getting closer and closer to the cost of coal generation. And you look at that with the
environmental benefits of the biomass, it really makes sense to do the research now to get it into
production as soon as we can.”

Dynegy is looking for farmers to grow miscanthus within a 50-mile radius of one of its central
Illinois power plants. But the company doesn’t know how many farmers it will be able to find.
Even if enough farmers are interested, dynegy is still working out the specifics of harvesting,
shipping, and burning grass effectively.

Miscanthus and biomass crops such as corn for ethanol and soybeans for soy diesel are just part
of a growing renewable energy market. And they face plenty of competition. Hans Detweiller is
with the environmental law and policy center, which advocates renewable energy in the Midwest.
Detweiller says wind and solar power generation are simply more established than biomass right
now:

“Biomass energy has more questions I think in the minds of the public than some of the other
energy sources, but we would like to see more of it. Especially where you can get parallel
benefits such as increased water quality, increased wildlife habitat, things like that.”

Detweiller says miscanthus could fit that billing, but other biomass crops might be more suitable.
Depending upon who you talk to, fields of young aspen or willow trees could even be the biomass
crops of the future. And Detweiller says a native plant like switchgrass is an attractive option
because it does not grow nearly as thick as miscanthus allowing wildlife to forage more freely.

But it’s that thickness that researcher John Clifton brown says makes miscanthus so appealing
and potentially so profitable to a farmer. As he stands next to a wall of miscanthus, Clifton-
Brown says the crop he’s grown in Ireland for a dozen years will only perform better in America.

“So try it. Suck it and see as we say in Europe.”

Clifton-Brown’s miscanthus is harvested only once a year. Others biomass crops are chopped off
a few times. They each have slightly different growing seasons, but all have at least one thing in
common. They represent a future where the energy we mine today could eventually be mowed.
