You might think that the countries with the most development are cutting down the most forests. But a new report by the United Nations shows that the United States and much of Europe are showing net increases in wooded areas. Julie Grant reports:
It’s the countries where a lot of people are poor, or face conflict, where clear-cutting and uncontrolled fires are continuing deforestation. The UN’s Food and Agriculture Organization has just issued a report on the the world’s forests. It finds that about 32 million acres of woods are lost each year.
That meant a loss of 3% of the world’s forests between 1990 and 2005. One of the agency’s foresters says the net loss is actually lower than in the past, but he says the world is still losing woodlands at an unacceptable rate.
Africa, Latin America and the Caribbean are losing the most forests. The report says most of that land is being converted for farming. The study credits economic prosperity and careful forest management for forest gains in the US, East Asia, and much of Europe.

Environmental work isn’t just for young professionals anymore.
Retired engineers, former biology teachers, and others with time on their hands are working on
environmental problems as volunteers. The Great Lakes Radio Consortium’s Jennifer Szweda Jordan
reports on how senior citizens are keeping environmentally active:
(Sound of bird)
75-year-old Ivan Pettit is officially retired from his job as an environmental regulator, but he
hasn’t stopped monitoring streams, promoting recycling, and solving a nagging safety issue in his
state.
(Sound of walking)
On a sunny day in Oil Creek State Park in northeast Pennsylvania, he drops a stone down a corroded
pipe.
“Okay, go.”
(Sound of rattling, splash)
Pettit is estimating the depth of this remnant of an old oil well. It’s one of thousands of
abandoned oil wells in this region. The wells date as far back as 1859. Pettit and a team of senior
volunteers regularly hunt for old wells. The seniors’ work improves water quality and safety for
hikers and hunters, and Pettit says it helps keeps him fit.
“It is work that I have always enjoyed doing as well as getting you outdoors and being able to
observe the things that’s going on around you, that is not a sedentary task whatsoever.”
Pettit belongs to the national Environmental Alliance for Senior Involvement. The group claims
members as young as fifty-five. Pennsylvania has the third highest number of residents older than
sixty among U.S. states. Its active Senior Environmental Corps is touted as a national model, and
has been honored by the United Nations Environmental Program.
But senior groups across the nation are working on environmental problems. In Cape Cod, they
monitor West Nile virus. Seniors clean hazardous waste sites in Indiana. Michigan volunteers
install solar water heaters on poor peoples’ homes.
It’s a fast growing program. In 1993, 26 older adults made up the Senior Environment Corps. A
decade later, over 100 thousand were involved in work across the country.
Ivan Pettit’s work looking for old oil wells is the kind of effort that makes a real difference.
Besides being a hazard for hikers and hunters, some of the old wells seep oil into the ground and
it gets into streams.
In less than two years, the seniors have found almost two hundred wells. Environmental Alliance for
Senior Involvement president Tom Benjamin compares that to two college interns who worked full-time
one summer, and found fewer than fifty.
“Most of these individuals that were volunteers know that community and know the area. They grew up
there, they hunted those woods, they know what a oil well looks like, so they have some instant
recognition.”
(Sound of forest)
Every other week, from spring to fall, the well hunters line up horizontally, twenty feet apart,
and comb a section of forest. Some well holes are several feet across and twenty feet deep. Others
have narrow openings, but drop as deep as a thousand feet. Evelyn Kolojejchick and her husband John
lead Ivan Pettit and other volunteers in seeking out the wells and marking coordinates.
“Ok, longitude is?”
“Seventy-Nine.”
For both Evelyn and John Kolojejchick, well-hunting and other environmental projects are an
extension of teaching high school science for thirty years. Evelyn once aimed to spark interest in
many young minds. Now she feels she’s working on a smaller scale, but hopes to remain effective.
“I belong to Audubon, used to belong to a lot of other environmental organizations and it just
seemed like you needed… you needed to do something that was going to make a difference. I never
had any money to donate to all of these causes and you just you know, you want to do something that
an individual can do.”
Recently, the seniors saw results of well-hunting. They found sensitive species in a stream that
had once been polluted. Several oil wells nearby had been sealed with cement to keep acid mine
drainage out of the water.
“The first year we tested it for aquatic life, there was almost nothing there. And yesterday when
we were there, we had better diversity in that stream than we have in some of our streams that we
test all along that we know don’t have those kinds of problems. So they have made a significant
difference on that stream by plugging those wells. It’s remarkable.”
And it’s the kind of reward that these senior citizen volunteers had hoped for: making a difference
Cell phones were a popular holiday gift this year. That means old phones will wind up in the garbage. A cell phone company from the Midwest is one of several firms that are pledging to reduce the number of old wireless phones that wind up in landfills.

Cell phones will be a popular holiday gift this year. A cell phone company from the Midwest is
one of several firms that are pledging to reduce the number of old wireless phones that wind up in
landfills. Chuck Quirmbach reports:
By some estimates, U.S. consumers discard more than 100-million cell phones a year. The
phones are small, but usually contain toxic chemicals like lead and cadmium that can leak in
landfills. Illinois-based Motorola and nine other cell phone manufacturers have pledged to the
United Nations to address the environmental issues linked to cell phone disposal. Motorola
official Craig Liska says the companies wanted to keep some control over the process:
“We wanted to make sure there wasn’t a global regulation that came out that kind of limited the
solutions because we wanted to have the flexibility to have the proper solutions in place in the
proper place of the world.”
If you want to get rid of an old cell phone now, you may be able to take it to a dealer for
reprogramming or perhaps have the toxic metals removed before dumping. The cell phone
makers are pledging to work on more options. They say they’ll also try to design phones that are
more eco-friendly.

A recent United Nations report indicates the earth’s population has doubled since 1960. The report says the result of that growth is that humans are altering the planet on an unprecedented scale. The Great Lakes Radio Consortium’s Lester Graham reports.
In its report, the United Nations Population Fund said that with six-point-one billion people on earth, humans are using more resources than ever before. The report indicates rising affluence and consumption along with the growing population are combining to cause extensive environmental damage. The report explains that increasing population itself does not mean increasing damage to the environment. But to be sustainable where the population is growing fastest, Asia and Africa, those regions must have better access to outside resources and technology to better manage their own natural resources, and the political will to use them responsibly. Without the resources and political will, the report indicates that growing populations in undeveloped areas tend to strip the ground clear of natural resources as well as damage the environment and induce famine and disease.

The terrible events in New York City and Washington D.C. have left a legacy of personal tragedies. For Great Lakes Radio Consortium commentator, Suzanne Elston, the story of September 11th, began as a journey of peace.
I’ve never been to New York City. So when we got an invitation to visit the Big Apple and participate in a children’s peace festival, we jumped at the chance. My husband Brian and two of our kids, Peter and Sarah, were going to be part of a church service marking the opening of the 56th session of the United Nations General Assembly.
Sarah was going to carry the Canadian flag and Peter was going to give a reading. The kids were wired and so were we.
Our plan was to leave Toronto Tuesday morning by train. The daylong trip would take us to New York City. We’d have all day Wednesday to do touristy things before the service on Thursday. We’d even managed to get tickets to a Broadway play. It all sounded so exciting that I couldn’t believe that it was actually going to happen.
We’d been on the train for about an hour when we first heard the news. Our traveling companions were 18 members of the Toronto Children’s Peace Theatre, also en route to the peace festival. The director of the company received a cell phone call that gave us sketchy details of the initial attack on the World Trade Center.
At first I refused to believe it. Here we were heading for an international children’s peace festival.
It felt like we were on the voyage of the damned. We continued on our journey, barreling down the tracks to a destination that we knew we would never reach. We heard rumors – the border was closed, there was shooting in the streets. People with cell phones were frantically trying to get a hold of somebody they knew who could give us an update.
The children from the theatre group were particularly upset. For most of them it was their first time away from home, and they were scared. As we discussed the latest details that we’d heard, one of the kids started to throw-up.
We moved to another car and tried to explain to a group of university students from England that they wouldn’t be flying home the next day from New York. As the news continued to filter in, we soon realized that they wouldn’t be flying home from anywhere. An elderly couple at the back of the car sat in stony silence. Their daughter worked at the World Trade Center and they were frozen in fear.
The conductor was stuck like a moose in headlights. Most of the passengers still didn’t know what was going on. My husband finally took him aside and explained that he had to make an announcement. People needed to make arrangements, to talk to their families. But he was just a kid and as scared as the rest of us. He wanted to wait until he had something official from Amtrak’s head office.
Finally, at 11:00 a.m., he made a formal announcement. The border was closed and we all would be disembarking at Niagara Falls. It was Tuesday evening by the time we got home and saw the horrific images of what had happened.
It wasn’t until then, when we were safe and home and together that we had a shocking revelation. The first stop on our sightseeing trip was going to be the World Trade Center. For the sake of a mere 24 hours we could have been buried at the bottom of that rubble like so many others.
Our great journey of peace ended with many prayers. We prayed for the victims and their families, we prayed for peace. Finally, we gave a prayer of thanks that we’d all made it home safely. After witnessing Tuesday’s horror – that was a gift beyond measure.

Great lakes radio consortium’s Lester graham reports.
Many researchers in a number of different fields are coming to the same basic conclusion: the earth is warming and it’s affecting the Great Lakes. So far, the effects have been difficult to track, unlike watching the day-to-day changes in the weather. Measuring climate change requires measurements over many decades, or better yet over centuries. There are only a few places where weather measurements have been taken over that long of a period. But, where they have, researchers are finding weather is becoming more chaotic and indications are that the long-term climate is warming.
Many climatologists believe that warming is due at least in part to greenhouse gases, that is, pollution in the upper atmosphere trapping more of the sun’s heat, much in the same way a greenhouse works.
Taylor Jarnigan is a research ecologist with the U-S Environmental Protection agency who’s been looking at one aspect of climate change. He’s been studying whether increasing amounts of lake effect snow from Lake Superior over the past century, especially the past 50 years, is evidence of a change in the temperature of the lake. Preliminary study suggests that the lake’s surface temperature is warming, and that causes more snow when cold air passes over it. But he says the amount of snow has varied widely from year to year.
“Some of this variability is certainly due –in my opinion– to an increasing volatile climate system itself. El niño and la niña are becoming more intense, so you have an increasing oscillation between, say, an usually warm summer followed by an unusually cold winter which tends to produce an unusually large amount of snow.”
The surface temperature of the lake has only been monitored for a few decades, while snowfall depths have been recorded for much longer. Jarnigan says, since there seems to be a direct correlation between the surface temperature of the lake and snowfall, he can calculate the temperature of the lake going back more than a century, and finds that Lake Superior is getting warmer.
When researchers find direct measurements that have been taken for more than a century, they feel fortunate. For example, John Magnuson with the University of Wisconsin has been reviewing the conclusions from the Intergovernmental Panel on Climate Change. That’s the international organization established by the United Nations to study global warming. As a part of that review, Magnuson has been looking over shipping and harbor records that date back 150 years or more to see if there’s evidence of global warming. One thing he’s learned is that lakes and streams aren’t iced over for as long as they once were.
“And in the last hundred-and-fifty years we’ve seen significant changes in lakes around the entire– lakes and streams around the entire northern hemisphere. The date of freezing on the average and the date of break up is changing by about six days per century.”
And Magnuson says that six day change on both ends of the freeze-thaw cycle mean that there’s nearly two weeks less ice coverage than a century ago.
That seems to bolster research at the National Oceanic and Atmospheric Administration’s Great Lakes Ecological Research Laboratory. Studies there indicate that over the last several years Great Lakes ice coverage on average is not as far ranging and doesn’t last as long as it did historically.
There’s no certain way to tell what might happen to the Great Lakes if the apparent warming trend continues.
But there are some ways to speculate. There are at least two computer models that try to estimate how much warmer the climate in the Great Lakes region might become by the year 2090. Based on those models, researchers have tried to figure out what that might mean for the area. Peter Sousounis was working at the University of Michigan at the time of that research. He says using either computer model it looks as though crops would produce more. Soybean yields could double. But other predictions are not as beneficial. It looks as though Great Lakes water levels would drop, probably about three feet more than they’ve already dropped, causing some problems for shipping. The study also found algae production would decrease by 10 to 20 percent. That’s important because algae provide the base for the Great Lakes’ food chain. Pine trees might also be all but eliminated from the region, and Sousounis says dangerously high ozone days might occur twice as often.
“Our findings indicate there are some potentially serious consequences in terms of reduced lake levels impacting shipping across the region, some serious economic impacts that if we don’t learn how to deal with these, there are going to be some serious changes in our lifestyles.”
Critics say the models can’t represent all of the variability in nature, so it’s difficult to be sure about any of the predictions. An adjustment here or there can lead to all kinds of alternative scenarios. Sousounis concedes more work needs to be done and more variables plugged into the models, but he’s convinced change will come; the degree of change is the only question.
These days, very few scientists argue against the studies that suggest the earth is warming. John Magnuson with the University of Wisconsin says a few DO argue that the change might merely be natural climate variability – that is, Mother Nature taking an interesting twist– and not necessarily a warm-up caused by manmade greenhouse gases.
“The skeptics, or the more cautious people, what they do when they look at that range of variation over the last thousand years, what they see is there is a signal in the warming that’s coming above the historic variation of climate. And, the climatologists of the world collectively feel there’s very strong evidence that warming is occurring, that greenhouse gases are a very significant part of that warming.”
Magnuson says most mainstream scientists agree climate change is happening, and even dramatic reductions in greenhouse gases won’t prevent some continued global warming over this century. But most say reducing pollution would slow the rise in temperatures and curtail the warming sooner. Only time will tell how that warming will change the Great Lakes region, and all of the researchers we talked to say in the meantime we’ll likely see more chaotic roller coaster type weather patterns as never before in recorded history.

Researchers are trying to determine how global warming might affect this region. The Great Lakes Radio Consortium’s Lester Graham reports.
Using two different sophisticated computer climate models, researchers are asking questions such as what happens to the water levels in the Great Lakes. Both models predict they drop even farther, causing shipping problems. They predict crops will produce more, and they predict some trees will die off. Peter Sousounis is one of the researchers studying the models. He says the region needs to consider what appears to be happening.
“I’m concerned that we won’t be prepared, we will not have done our homework. I think as a society we can certainly adapt, if we are given enough time. And if we don’t adapt, life might adjust to a new mean state all around.”
While nearly all climatologists believe the earth is warming, not everyone agrees whether the changes will be harmful. Sousounis agrees more research needs to be done to try to determine what the effects might be. For the Great Lakes Radio Consortium, this is Lester Graham.
A report released this fall by the U.N. Development Program, found that 20 percent of residents in high income countries now consume a whopping 86 percent of the world’s consumer goods. Most of that spending comes now, during the holiday season. Great Lakes Radio Consortium commentator Suzanne Elston suggests that it’s high time we learned to live a little more simply:
