In the summer, local weather forecasts often include information about dangerous ozone levels. But scientists are learning more and more about another type of pollution that can reach harmful levels even in the winter months. And as the Great Lakes Radio Consortium’s Sarah Hulett reports, we might be hearing more about this type of pollution in our daily weather reports:


Parts of the region recently reached “code red” for poor air quality. And
that had some people perplexed. Warnings about dangerous levels of ozone are
frequent on hot summer days, especially in urban areas. But this was the
middle of winter.


The warnings were for high levels of tiny particles that federal regulators
only recently began monitoring. They’re spewn from diesel engines,
factories, power plants, and fireplaces. Air monitors in Michigan,
Minnesota, Pennsylvania, and Indiana recently registered unhealthy levels of
these particles – some of them for a few days straight.


Jim Haywood says the problem was an unusual weather event for this time of
year. Haywood is a meteorologist with the Michigan Department of
Environmental Quality. He says a high pressure system moved very slowly over
the Great Lakes region for several days. When you get high pressure, the air
below sinks, generating a layer of warm air that acts like a lid.


“So that warm air that was sinking effectively stops at a few hundred feet
from the surface of the ground. It acts like a cap. It does not let any of
the pollutants that are released at the surface pop up through that cap.”


So all the pollutants that would have gotten picked up and diluted by the
wind instead just hung out for days – building up, and reflecting sunlight
to create haze.


Eventually, a cold front pushed the high pressure system out of the way, and
took the pollution with it. But what about those few days when the Environmental Protection Agency was warning about unhealthy levels of particulate pollution? For people with
heart or lung disease, agency health officials say short-term episodes can
lead to asthma attacks or even heart attacks. And they say healthy children
and adults can experience throat and lung irritation.


Susan Stone is an environmental health scientist with EPA. She says
particle pollution warnings could soon become a staple of the daily weather
report – much like the familiar summer ozone warnings.


“With ozone, we have the network in place to be able to deliver those
forcasts, people are used to hearing that on TV, and we are working to
provide that same level of coverage for particle pollution.”


Stone says EPA is rolling out a new program called Enviro-Flash
nationwide. It sends real-time air quality information to people’s email
accounts or pagers. EPA is offering the service through state
environmental agencies. And beginning in 2010, areas that register
unacceptable levels of particle pollution will be required to clean up their
air.

A Closer Look at Mercury Hair Test

Health officials are experimenting with another way to gauge the level of mercury in people who eat a lot of fish. The only test sample needed is… hair. The Great Lakes Radio Consortium’s Chuck Quirmbach reports:


Doctors can already test your blood and urine for mercury. Now, as a less invasive technique, some health officials can test the hair near your scalp for the toxic chemical. There’s some debate over the quality of the tests, the lab analyses, and over what a high test reading means. The federal health warning for mercury in hair is one part per million. But that’s for susceptible populations like an unborn fetus.


Jack Spengler is a professor of environmental health at Harvard University. he recently ate a lot of fish and says his hair tested out at 3 parts per million of mercury.


“But I’m not going apoplectic about it because I know if I just watch my consumption, I can moderate that over time… and there’s that safety margin…that I suspect I’d have to be much higher for much longer to really have symptoms. ”

Prolonged high levels of the most toxic form of mercury, methyl mercury can trigger various health problems in adults such as memory loss and cardiovascular damage.

The message from advertisers this holiday season seems to be, buy more because you and your family deserve it. Retailers are hopeful we’ll all spend just a little bit more to make the holidays shiny and bright. The Great Lakes Radio Consortium’s Lester Graham went to the shopping mall with a guy who thinks we ought to scale back our spending during the holidays:


Bob Lilienfeld is one of the co-authors of a book called Use Less Stuff. As you might guess, he’s an advocate of using fewer resources, including buying less stuff during the holidays. We asked him to meet us at a big shopping mall to talk about why he thinks buying less means more.


Lilienfeld: “I want you to go back to when you were a kid. Think about the two or three things in your life, the things that you did that made you really happy. I guarantee none of those have to do with physical, material gifts. They have to do with time you spent with your family or things you did with your friend. But, it wasn’t the time you said ‘Oh, it was the year I got that train,’ or ‘the year I got those cuff links,’ or ‘when I got those earrings.’ That’s the principle difference. We’re trying so hard to be good and to let people know that we love them, but the things that we love about other people and that they love about us have nothing to do with material goods.”


Graham: “There’s a certain expection during the holidays, though, that we will get something nice for the people we love and here at this mall as we’re looking around, there are lots of enticements to fulfill that expectation.”


Lilienfeld: “That’s true, but we’ve been led to believe that more is better, and to a great extent more gifts is not better than fewer gifts. Quality and quantity are very different kinds of thoughts and we’ve been led to believe economically that quantity is more important. But, in reality it’s the qualitative aspects of life that we long remember and really are the ones we treasure.”


Graham: “Now from the news media, I get the impression that if I don’t do my part during the holidays in shopping, that it’s really going to hurt a lot of Americans, the American economy. $220-billion during the holiday season. It’s 25-percent of retailers’ business. So, if I don’t buy or if I scale back my buying, won’t I be hurting the economy?”


Lilienfeld: “It’s always been 25-percent of retailers’ business, even if you go back 30 or 40 years, and that’s probably not going to change. It comes down to your thinking through what’s good for you, what’s good for your family, what’s good for your friends and not worrying so much about what’s good for the economy and what’s good for big companies.”


Retailers are expecting sales to be better this year than last year. So, that simpler lifestyle that Lilienfeld is talking about is not widespread enough to have any real impact on the overall shopping season. But apparently the economy isn’t strong everywhere.


We talked to some shoppers about their holiday shopping plans and the idea of simplifying things. Many of them told us that the economy was forcing them to cut back on gift buying…


Shopper 1: “Well, because of my limited budget, I have to buy, like – I have a list – and I have to buy one at a time, so, being pretty poor is being pretty simple. I’m kind of already living that way.”


Shopper 2: “I don’t need to celebrate Christmas by buying people gifts. And I can give people gifts all year long. And I — Christmas is kind of sham-y to me.”


Shopper 3: “This year, yeah, my family is like, ‘Don’t get me anything.’ I’m going to do something, but hopefully it will be smaller and less expensive and all that.”


Shopper 4: “Well, I don’t feel compelled to buy something because an economist says it’s my part as an American. And I think people are going to get smarter and smarter about how they spend their money and the almighty dollar.”


With the constant messages on television, radio, the Internet and newspapers to spend, there’s a lot of persusive power by advertisers to buy now and think about the cost later.


Since Bob Lilienfeld is such an advocate of a simpler lifestyle, it makes you wonder about his own shopping habits.


Graham: “Do you ever find yourself in the shopping mall, buying stuff for the folks you have on your Christmas list or your holiday list?”


Lilienfeld: “All the time. But, what I try to do is two things. One is think about the fact that more isn’t necessarily better. But the other thing I really try and do is look for gifts that are what I call ‘experiential’ as opposed to material. Tickets. Things where people can go to plays or operas or ball games so that they have an experience. Same thing with travel. I mean, if I could give my father a gift or if I could help him afford to go somewhere, like to see me and the kids, that gift is probably worth a lot more to both of us than if I just gave him a couple of bottles of wine.”


And Lilienfeld says you don’t waste as much wrapping paper when you wrap up tickets.

Companies Push for Forest Certification

  • Magazine publishers and other companies are thinking ahead and getting their paper from forests that have been certified. But what does this really mean? (Photo by Stanley Elliott)

Officials in the Midwest want to prove they’re not damaging their state forests. States that sell timber to paper companies are spending thousands of dollars to earn a certificate that says they’re managing the forests in a sustainable way. Paper producers are demanding that state foresters earn certification because officials want to stave off protests from consumers. The Great Lakes Radio Consortium’s Celeste Headlee reports:

Officials in the Midwest want to prove they’re not damaging their state forests. States that sell timber to paper companies are spending thousand of dollars to earn a certificate that says they’re managing the forests in a sustainable way. Paper producers are demanding that state foresters earn certification because officials want to stave off protests from consumers. The Great Lakes Radio Consortium’s Celeste Headlee reports:


It’s lunchtime and employees on break from Compuware in downtown Detroit are browisng through the magazine racks at Borders. Melody Kranz says she reads three different magazines every month. She says she is an avid recycler and an impassioned environmentalist, but never considered what kind of paper was going into her magazines.


“I don’t know why I haven’t thought about it, I just haven’t. I will now. Because I’m a gardening nut, I love to garden. So yeah, I just never really thought about it.”


But executive David Refkin is betting that Franz and others like her would think twice before picking up Time Magazine if they thought a forest was demolished to make the paper. Refkin is the Director of Sustainable Development for Time Incorporated. He says he’s noticed a strong surge in environmental awareness over the past two or three years.


“We don’t want people looking at a magazine and feeling guilty that a stream has been damaged and the fish are dying in there, or that habitats aren’t being protected because people are practicing bad forestry practices.”


Refkin says his company wants to take action now, before consumer groups decide to boycott its magazines over ecological issues. Time uses more coated paper for its publications than any other company in the U.S. The company is asking that 80 percent of all paper products Time buys be certified by 2006.


To the average consumer, that may not seem like big news. But for paper producers and foresters, it’s earth shattering. Larry Pedersen is with the Michigan Department of Natural Resources. Pedersen says getting certified means years of work for state employees. The government has to prove to investigators that its management standards take into account issues such as biodiversity, water quality, soil erosion and wildlife habitat. Pedersen says the state is also required to provide records for each tree from the moments it’s planted or inventoried to the time it’s cut down and then made into planks or paper. But he says it’s worth the effort.


“A number of wood and paper-using companies brought it to our attention that they needed to have certified products because their consumers were demanding those. And with us having four-million acres of state forestlands, we saw the writing on the wall that we needed to jump on this.”


State forests in the region generate a lot of revenue. Wisconsin’s forests earn two and a half million dollars from timber sales and Ohio pulls in almost three million. Michigan’s forests bring in 30 million dollars annually. Earlier this year, Michigan’s Governor Jennifer Granholm announced that all state forests will be certified by January 1st of 2006. And the Great Lakes State is not alone… New York, Wisconsin, and Maine are also pursuing certification and Ohio and other states are considering it.


Andrew Shalit, with the environmental activist group Ecopledge, says he’s glad Time Warner is encouraging paper companies and state governments to get certified. But he says that doesn’t necessarily mean the paper is produced in an environmentally friendly way.


“It’s great to say that they’re going to get all of their paper from certified forests. The question is, who is certifying? And in the case of Time Warner, a lot of the forests are certified by a group called SFI, the Sustainable Forestry Initiative, and their standards are so weak as to be almost meaningless.”


There’s a heated debate over just what certification means. There are currently two groups that certify forests in the U.S. The Sustainable Forestry Initiative, or SFI, was originally founded by the timber industry but is now an independent body. The Forest Stewardship council, or FSC, came out of the environmental movement… or more specifically, out of the effort to protect South American rainforests. Shalit says he doesn’t think SFI certification is as rigorous or as comprehensive as FSC.


“It really is a problem for the consumer because you see something in the store and it has a little green label on it with a picture of a tree and it says sustainably certified, and you think you’re buying something good. It’s hard for the individual consumer to keep up with that.”


Shalit says several states, like Michigan, have solved the dilemma of rival certification programs by getting dual certification. he says although the system has flaws, it will improve if consumers demand more stringent forestry regulations.


Executives at Time Warner hope they can avoid boycotts and pickets by taking action preemptively. The company is leading the push for forest certification in the U.S., and environmentalists say the federal government may have to bow to pressure eventually and get the national forests certified as well.

Presidential Profile: George W. Bush

The presidential candidates haven’t spent a lot of time talking about conservation or the
environment. On the campaign trail, nature has taken a backseat to the economy and security. In
the first of four reports on the presidential and vice presidential candidates, the Great Lakes Radio
Consortium’s Lester Graham looks at the environmental record of President George W. Bush:


President Bush doesn’t often use the words “environment” or “environmental.” He prefers
“conservation.” It’s part of his philosophy. He believes we should manage resources and believes
the government has tipped the scales too far in favor of preservationists at the expense of business and agriculture. On his Texas ranch, Mr. Bush likes to exercise by cutting brush to manage nature. It’s could be a metaphor for how he sees the larger issue. It seemed that way when he talked about his approach to the environment during the second debate.


“I guess you’d say I’m a good steward of the land. The quality of the air’s cleaner since I’ve been the President. Fewer water complaints since I’ve been the President. More land being restored since I’ve been the President.”


While President Bush believes he’s striking the right balance between conserving natural
resources and not regulating business excessively, many environmentalists think the Bush
Administration’s approach to environmental issues is way out of whack.


Betsey Loyless is the Vice President of Policy for the League of Conservation Voters. The LCV
keeps track of votes and issues and grades politicians on their decisions.


“League of Conservation Voters gave George Bush an “F,” the first “F” we’ve ever given out in
modern history to a president because his policies of anti-environmentalism spread across the
board of dirty air, dirty water, degrading our public lands and jeopardizing our energy future by
focusing on 19th century energy policies that don’t meet our 21st century needs.”


President Bush largely ignores criticism from environmental groups. He sees them as extremists.
On the campaign trail, he frames the debate about the environment in terms of finding a better
balance between the protecting the environment and keeping jobs.


“If we want to keep jobs here in America and expand the job base, America must be the best place
in the world to do business. That means less regulations on our business owners.”


You would think that would make business and industry-types happy. But even there, the
President has his critics. The free-market supporters are disappointed in George Bush. They feel
he should have stuck to the ideas he had when he was running for president four years ago: Roll
back regulations that some businesses say cost a lot of money with little benefit to the
environment. The Property and Environment Research Center – self-described as the center for
free market environmentalism – gave the President a “C-minus” grade on his mid-term report card
because the free-market thinkers believe the Bush Administration compromised its original
proposals to please environmentalists and ended up pleasing no one.


Even some in President’s own party are unhappy with the Bush administration’s dealings with the
environment. The group, Republicans for Environmental Protection, backed by former Republican
EPA Administrators and other prominent Republicans say the President got it wrong. Jim DiPeso
is the group’s Policy Director. His group believes the Bush administration could have done more to
protect the environment.


“Well, our board took a look at the issue and decided that President Bush had not earned our
support based on his record over the last four years. So, because we have a policy of not
endorsing Democrats, the only alternative that we had in order to express our disappointment was
simply to withhold an endorsement for the presidential race this year.”


But the majority of Republicans say the President is making progress on environmental issues.
Lynn Scarlett is one of the architects of the Bush environmental policy. She is Assistant Secretary
of the Department of Interior’s Office of Policy Management and Budget.


“This administration has the highest dollars ever expended by any administration going towards
environmental protection whether it’s on the pollution side and pollution clean up or on the land
management and conservation side. We have a number of new programs the President initiated.
So, there is an awful lot that is occurring that is getting results on the ground.”


President Bush believes the government should be partners with private landowners and
industry… encouraging them to be more environmentally friendly instead of relying on regulations
to mandate less pollution and better stewardship of the land. Environmentalists say that leaves too much to chance and the potential cost to the planet is too dear.

Gao: Great Lakes Need Better Monitoring

A new report says the U.S. Environmental Protection Agency lacks the information it needs to assess the overall health of the Great Lakes. The Great Lakes Radio Consortium’s Sarah Hulett reports:


A water quality agreement between the U.S. and Canada requires the two countries to reduce pollutants in the lakes and monitor progress in restoration.


But the Government Accountability Office report says coordinated monitoring between the two countries has not been fully developed. The GAO is the investigative arm of Congress. The reports says disparate agencies – at the federal, state, provincial and local levels – are monitoring the lakes, but it says information from those groups does not provide an overall assessment of the lakes. The GAO is recommending that EPA develop a system to ensure complete, accurate and consistent information.


In its response to the report, EPA said it agreed with that recommendation and is taking steps to coordinate, monitor, and develop standards for measuring the health of the Great Lakes.

Clear-Cut Demonstration Angers Forest’s Neighbors

Most forests in the Great Lakes region are privately owned. That concerns the U.S. Forest Service because the agency says many forest owners don’t know how to properly manage their woodlands.

Most forests in the Great Lakes region are privately owned. That concerns the U.S.
Forest Service because the agency says many forest owners don’t know how to properly
manage their woodlands. The Great Lakes Radio Consortium’s Julie Grant reports that a
new education project that demonstrates tree-harvesting techniques has angered some residents:


(sound of chain saws)


Workers are cutting down trees in a fifty-year-old pine crop. At the same time, state
foresters are leading a botanist, a private tree farmer, and a reporter through this forest
education site. One of the foresters, Rick Miller, is directing the chain saws to show what
needs to be cut for what’s called a “crop tree release.”


“This one here we selected out with the orange flags, the trees that show the best form and
dominance in the crown. They have a nice big healthy crown. And then what we’re doing is removing
any trees that are touching the crowns of those ones that are orange, and just opening it up
to give the crown more room up there to spread out and possibly increase their growth and their
vigor.”


A forest owner who wants to make money off his pine stand might do a crop tree release to
improve the quality of the remaining timber. The bigger the tree, the more money it’s worth
to a logging company.


Heading deeper in, a crop of pine trees lined up like soldiers trails to our right, and wilder
hardwoods shade us from the left. There are signs to demarcate different timbering techniques:
improvement cut, understory removal, selective cut. Project manager Frank Corona stops at one
section of oaks, maples and cherries.


“You have small trees, medium trees, some larger trees. Trees are probably selectively
harvested in here and you have all different ages of trees in this stand…”


The cool shaded path abruptly opens up. The lush canopy is replaced by harsh sunlight.


GRANT: “Oh wow, so this is the clear-cut…”


CORONA: “This is the clear-cut.”


The forest is gone… cut to the ground. All that remains are the 120 hardwood stumps on
the torn-up dirt. Botanist Steve McKee suports construction of the demonstration site.
But he also loves trees.


GRANT: “What do you think when you see that clear-cut?”


MCKEE: “Well, clear-cuts are never pretty, ya know? So, uh, I think the most shocking thing
for me is I’ve walked in this my whole life and it was surprising. But I knew it
was coming too, so…”


But some people in the community say they didn’t know the demonstration project would include
clear-cutting older trees. Anne McCormack hikes the Mohican nearly every day, clearing trails,
cleaning garbage, or enjoying the woods. The education site has been roped off from the public
during construction. But she found out there was a clear-cut demonstration in an old growth
section of the forest.


“So, I just was… I was just shocked. I mean I can’t say anything more. I just felt
terrible for… I felt terrible for the trees that stood there since before white settlers
were even in Mohican. And there they just were bulldozed and chain cut for education.
I mean, it doesn’t add up.”


McCormack’s not the only one who’s upset. A lot of people didn’t realize this is what
the Forest Service had in mind. Back at the clear-cut site, Corona says many trees suffer
from disease when they mature to 120 years. He says it’s a good age for private land owners
to consider the clear-cut option.


“This was a time where before they would rot out or anything and we see more damage, more
susceptibility health-wise in the entire stand, we could make a harvest in here and utilize
those trees and start this whole new cycle of growth in here.”


The foresters and forest owners say clear-cutting is a viable option, and just one of the
many examples at the demonstration project in the Mohican forest.


Tree farmer Scott Galloway says people need to understand that owning a forest is another
form of family farming. For instance, he got a call recently from a man who inherited 30
acres and needed money right away. He doesn’t know how to manage his tree crop.


“Where does he go? How do you make the right decisions quickly? The faster he can make
decisions, in his lifetime with his forest, the sooner he’ll be able to enjoy the benefits
of those decisions. It’s all about forestry, wildlife, natural resources. So the more education he
can get, the better those decisions will be and the better off all of us are environmentally because of it.”


The Forest Service says a demonstration project is needed because forest acreage is getting
cut up into smaller and smaller parcels. That means the forests are owned by more and more
people who need to know how to manage their timber. The Forest Service hopes this project
will help them make better decisions.

This week, researchers, government agencies, industry, and environmental
groups are meeting in Toronto to try to assess the overall environmental
health of the Great Lakes. The gathering is known as the State of the Lakes
Ecosystem Conference. And as the Great Lakes Radio Consortium’s Mark Brush
reports, the group says there’s good news about the amount of forestland in
the region:


The report prepared for this year’s conference says there is more forestland
in the Great Lakes Basin when comparing recent data to data collected more than
a decade ago. The report’s authors say forestland now covers a little over half
of the basin’s total land.


Constance Carpenter is with the U.S. Forest Service. She helped develop the report.
She says forests are crucial to maintaining the environmental health of the Lakes.


“They do a lot of things in terms of water quality. They’re able to provide conditions
that really contribute to watershed health in terms of, you know, moderating flood peaks,
storing water, filtering pollutants, transforming chemicals, all those things.”


Carpenter says one of the reasons forestland is increasing is because fewer people are
farming. She says as people leave behind fields and pasturelands, those lands often
convert back to forestland. The authors caution that their data did not look at whether
these forests are near lakes and streams, where their influence on the overall health of
the Lakes is greatest.

Canadian Groups Concerned About Water Withdrawals

A Toronto researcher says most communities are underestimating a potential source
of cheap electricity – raw sewage. The Great Lakes Radio Consortium’s Karen Kelly reports:


University of Toronto professor David Bagley collected waste water at a North
Toronto water treatment plant. He took the sewage into his lab, dried it and
then burned the solids to see how much energy they produced. He estimates the
energy produced from sewage at three treatment plants could produce more than
100 megawatts of electricity. That could be enough to keep a small town going
for a year. But Bagley says few take advantage of this resource.


“Our measurements show that there’s enough energy that we should be able to
completely offset the electricity needed to run the plant, and have extra
left over the send back to to the grid.”


Bagley finds communities are reluctant to invest in the equipment they’d
need to convert sewage into power. But he’s hoping to to design a cheaper
and more efficient system so more people can get the most out of their sewage.

Ijc Report: Mixed Prognosis for Great Lakes

The latest report on the overall health of the Great Lakes shows
mixed progress in cleaning up the lakes. The International Joint
Commission says there have been some improvements, but there are
still many areas that need to be worked on. The Great Lakes Radio
Consortium’s Stephanie Hemphill reports:


The IJC is an agency made up of Canadian and U.S. officials who
monitor the overall health of the Great Lakes. Every two years, the
agency issues a report.


This year’s report says the two governments have made progress in
cutting releases of many toxic chemicals. And scientists are closer to
understanding how global climate change is likely to affect the Great
Lakes.


But the report says other issues require urgent attention. It calls for
government action to reduce mercury emissions from coal-fired
power plants. Mercury can cause nerve and developmental damage
when it’s eaten in fish.


And U.S. Co-Chair Dennis Schornack says the governments should
do more to stop invasive alien species from getting into the Great
Lakes.


“We still don’t have measures in place that would stop ballast water
mediated transfers of species from abroad; we’ve still got a threat
with the Asian carp coming up the Chicago Ship and Sanitary Canal
and incomplete funding for the barrier to stop that invasion there.”


The report also urges scientists to figure out why Lake Erie’s water
quality is degrading again, after years of improvement.


And there are always new challenges, according to Canadian Co-Chair Herb Gray.


“There are new families of chemicals getting into the water. The fire
retardants, which are great for your furniture, but not great in drinking
water.”


This was the 12th biennial report on Great Lakes water quality. The
report says it’s now time for a comprehensive review of the
agreement between the U.S. and Canada to clean up and protect the
Great Lakes.
