The Environmental Protection Agency says the phase-out of a widely used pesticide is
working. They say the amount of methyl bromide companies have in stock has been
dropping since 2003. Christina Shockley has more:
Methyl bromide is a colorless, odorless gas used by crop growers to kill unwanted bugs.
Scientists say when the chemical gets into the atmosphere, it depletes the ozone layer.
Drusilla Hufford is with the Environmental Protection Agency. She says methyl bromide
is the fourth most widely-used pesticide in the United States:
“It’s used in soils where people are growing crops, it’s used to make sure that houses and
structures are free of pests, and it’s used to make sure that commodities that are shipped
abroad or brought into the United States are also free of pests.”
Methyl bromide was phased out of production in the US in 2005, except for limited
cases. So, for the most part, what’s used now was produced before then.
Hufford says many growers, especially in California, are increasing their use of safer
alternatives to methyl bromide.

Several retail stores have had to pull millions of aerosol string-in-a-can products. The GLRC’s Lester Graham reports:

Several retail stores have had to pull millions of aerosol string-in-a-can
products. The GLRC’s Lester Graham reports:
Stores such as Target, Dollar General, American Greetings, Limited Too, and Dollar Tree
were ordered by the U.S. Environmental Protection Agency to pull cans of Zany String,
Crazy String and Party Streamer from their shelves. The products contain banned
hydrochloroflourocarbons. The novelty items were all imported from China or Taiwan.
Adam Kusher is Director of EPA’s Air Enforcement Division:
“All the illegal product has been pulled from the shelves and is being destroyed.”
Hydrochloroflourocarbons or HCFCs deplete the earth’s protective ozone layer. Kushner
says the stores are responsible for making sure the products they import are not banned in
the U.S.
“So, the retailer should, through its contract, insist on verification of the contents of the
materials.”
All of the stores face civil penalties for selling the illegal products.
A new study shows that a ban on ozone-depleting chemicals has led to a slow recovery of the Earth’s protective ozone layer. Researchers say within the next 100 years, the ozone layer could be as strong as it was 25 years ago. But there’s still a lot of uncertainty about the recovery process. The GLRC’s Erin Toner reports:

A new study shows that a ban on ozone-depleting chemicals has led to a
slow recovery of the Earth’s protective ozone layer. Researchers say
within the next 100 years, the ozone layer could be as strong as it was 25
years ago. But there’s still a lot of uncertainty about the recovery process.
The GLRC’s Erin Toner reports:
The ozone layer protects the Earth from the harmful effects of ultraviolet
radiation, including skin cancer and damage to the environment. The
study’s authors say it shows a direct relationship between ozone recovery
and a ban on chlorofluorocarbons, which were used as a refrigerant.
University of Colorado Researcher Betsy Weatherhead says this is good
news, but people should still be careful.
“While ultraviolet levels are still high, and we expect them to be high for
at least the next 10 to 20, possibly 30 years, we have to be particularly
vigilant about protecting ourselves and our children against the harmful
aspects of UV.”
Weatherhead says ozone recovery faces some uncertainties… such as
rising global temperatures. She says that could stall recovery or lead to
record-low ozone levels.

However, by using methyl bromide, some scientists say we are damaging the ozone layer.
The USDA wants to increase the use of methyl bromide to keep invasive insects from getting into the country. But some environmentalists are fighting the plan, saying the chemical will do more harm than good. The Great Lakes Radio Consortium’s Chuck Quirmbach explains:

The USDA wants to increase the use of methyl bromide to
keep invasive insects from getting into the country. But
some environmentalists are fighting the plan, saying the
chemical will do more harm than good. The Great Lakes
Radio Consortium’s Chuck Quirmbach has more:
The U.S. Agriculture Department wants to nearly double the
use of methyl bromide. The compound is used as a pesticide
to fight invasive insects that come into the U.S. on wooden
pallets. But scientists say methyl bromide is harmful to the
stratospheric ozone layer. The Natural Resources Defense Council
plans to sue the government over its plan. David Doniger is with
the NRDC. He says more use of methyl bromide might reverse advances
made in protecting the upper atmosphere.
“The ozone layer has been badly hurt. It’ll take a long time – 50 years –
to fully heal it… and only if we get rid of all the ozone depleting chemicals.”
Doniger contends the Indiana company that’s a key producer of methyl bromide
has many other products and wouldn’t see any job losses if the government
plan is halted. The USDA argues there are no feasible alternatives to methyl
bromide, so the government says the chemical deserves an exemption from a
1987 international treaty that targets ozone depleting compounds.

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.

Trichloroethane or TCA is a solvent that contaminates groundwater
and erodes the ozone layer. It is present at many polluted sites across
the country. TCA comes from many common products such as glue,
industrial
degreasers, and aerosol sprays. Now scientists say they’ve found a
microbe
that can help clean it up. The Great Lakes Radio Consortium’s Tamar
Charney reports:
One way polluted water can be cleaned is to add bacteria that breaks
down the harmful substances. It is a process called bioremediation. In a
recent issue of “Science,” researchers at Michigan State University say
they’ve identified a microbe that could do this with TCA. Benjamin
Griffin is a doctoral student who worked on the project. He says they
found the bacteria in sediment in the Hudson River.
“They actually breathe TCA, so they respire it. They’re using this
chlorinated compound in the same way we use oxygen.”
The bacteria breaks down the TCA into other compounds. Those chemical
compounds can then be further broken down by other pollution-eating or
breathing bacteria. Up until now, scientists though there might not be
a
way to biodegrade TCA. For the Great Lakes Radio Consortium, I’m Tamar

The United Nation’s Environment Program says the Great Lakes are cleaner.
But a new report says the U.S. and Canada need to do more to prevent
problems due to urban growth, agricultural runoff and invasions of exotic
species. The Great Lakes Radio Consortium’s Lester Graham reports:
The U.N. report looks at what’s happened to the environment in the U.S. and
Canada for the last 30 years. It finds that there’s been significant progress
in protecting the ozone layer, reducing smokestack and auto emissions, and
slowing the loss of wetlands and other wildlife habitat.
The report in particular notes the progress made in cleaning up the Great Lakes. It
states that since 1972, the use, generation and release of several toxic
chemicals into the Great Lakes has been reduced by 71 percent. But, it also
finds that the two countries have not done a good job of stopping exotic
species such as the zebra mussel from damaging the environment of the lakes,
and it ticks off a list of toxic pollution problems from urban areas and
farms. The report concludes that North America’s global impact is disproportionately large compared to other countries in the world.

Winston Churchill once said, “Americans will always do the right thing — after they’ve exhausted
all the alternatives.” For Great Lakes Radio Consortium commentator Tom Springer, Churchill’s
wisdom could also apply to land trusts. After decades of rampant sprawl, more Americans are
joining land trusts to protect what’s left of the natural areas around them:
Like many people who love nature, it’s always been my dream to save wild land from development. When I was younger, it seemed like an easy thing to do. I planned to graduate from college, earn serious money, and spend most of my income buying rural real estate. Unfortunately, the big salary never materialized. After five years, I had bought just one piece of property: a three-acre parcel of woods that can only be reached by canoe.
Since going solo didn’t work, I decided to join a national organization that’s famous for saving wild land. With my annual dues, I got a static window sticker and a gorgeous magazine that featured the group’s newest preserves. But after a few years, the vicarious thrill of sending money to save far-off places started to fade. I really wanted to protect land that was close to home. Yet for this organization, my corner of southern Michigan wasn’t even on the map.
At long last, I have found a better way to stave off the bulldozers. Along with 1,000 local citizens, I’m an active member of a land trust. Land trusts are nonprofit organizations that work with private property owners to save natural areas from development. Sometimes they buy land to create preserves. They also accept donated land, and establish conservation easements to prevent future development.
In the past decade, the land trust movement has seen phenomenal growth. There are 1,300 land trusts nationwide, a number that’s more than doubled since 1990. Together, they protect 6.4 million acres — up 220 percent since 1990.
So why are land truth trusts so successful? I believe it’s because their mission is unabashedly local. They’re not preoccupied with Chinese panda bears, or holes in the Arctic ozone layer. They’d rather rescue the 100-acre woods down the road. Or protect a suburban stream that’s the last neighborhood refuge for tadpoles and snapping turtles.
In our capitalistic system, land is a commodity. Yet land trusts use the free-market to their advantage by purchasing land to prevent development. So this business-like approach also appeals to conservatives and moderates who may not otherwise support environmental causes.
Yet another appeal of land trusts is their hands-on, dirty-fingernails approach to conservation. There’s always much more for members to do than just stick a check in the mail. Land trusts rely almost solely on volunteers to maintain trails, conduct field surveys, or stuff envelopes around the office.
A few weeks ago, my land trust hosted a workday at a five-acre preserve that’s a mile from my home. For three hours, I joined a happy band of retirees, college kids, and recovering yuppies as they uprooted Japanese honeysuckle that threatens to crowd out native wildflowers.
This preserve is too small for any government agency to bother with. Yet we know it as a pocket wilderness, where cardinal flowers and bluebells bloom in the rich soil of a floodplain forest. Maybe it’s not one of the world’s last great places. But it’s our place — and it’s our land trust. And if we want to save the natural world, our own neighborhood is always a good place to start.

Great Lakes states are slowly complying with new EPA rules designed to reduce smog. The Great Lakes Radio Consortium’s Jonathan Ahl reports:
The US EPA is requiring states to reduce emissions of Nitrogen Oxides, a main component in smog and ground level ozone. Coal-fired power plants and industrial boilers are the main producers of the pollutants. John Summerhays is an environmental scientist with the EPA’s Midwest Office. He says the reduction is an attempt to improve public health:
“The smog and ozone can cause a variety of health effects that are principally hard on the lungs. It can contribute to various lung diseases, so this is a big step forward for public health protection.”
Illinois and Indiana recently had their emission reduction plans approved by the Federal Government. Pennsylvania and New York have also been approved. Ohio and Michigan still have yet to submit reduction plans. The deadline for implementing the measures is 2004. For the Great Lakes Radio Consortium, I’m Jonathan Ahl.
