You might think about imported oil and Saudi Arabia or Venezuela come to mind. But, the single biggest source of imported oil to the U.S. comes from Canada. And half of that comes from a dirty form of oil called tar sands oil. Lester Graham reports environmentalists are trying to use NAFTA to get restrictions on tar sands oil.
Environmental groups say extracting tar sands oil causes a lot of water pollution. Matt Price is with Environmental Defence Canada:
“We keep on presenting the evidence to the government, and they just sort of keep on ignoring it which is why we filed this citizens’ complaint.”
They’ve filed the complaint under the North American Free Trade Agreement. The say oil companies in Canada are not complying with Canadian environmental laws and that might be a violation of the NAFTA treaty. So, his group and others are taking the fight to Canada’s trading partners.

Food-packaging executives and

chemical bisphenol-A, often
called BPA, met in Washington
DC last week to come up with PR
strategies. Their message is:
BPA is safe. Lester Graham reports
someone took notes at that meeting
and then leaked them to reporters:
Lyndsey Layton got ahold of those notes. She reports for the Washington Post.
“According to these notes, they called it the ‘holy grail’ spokesperson would be a pregnant, young mother who would be willing to speak around the country about the benefits of BPA.”
Ironic in that many studies associate BPA with birth defects.
John Rost is the Chairman of the North American Metal Packaging Alliance.
He says the reporters got bad notes. He says it only came up because environmental activists used pregnant women to testify against BPA.
“We discussed that as an option and dismissed it and actually find it a little ironic that we are being criticized.”
Some retailers have taken toys and baby bottles made with BPA off the shelf in response to a consumer backlash.
It’s likely most consumers don’t yet realize the chemical also lines beverage and food cans.

In the dry American West, folks have been
duking it out over water for centuries.
But water shortages are new to the Southeast.
Many once thought the rivers would flow
forever. Now, North Carolina is emerging
from the worst drought in over a hundred
years. Julie Rose reports on a power
struggle has erupted over one of its
rivers:
(sound of inside a truck)
From a one-lane road way above the Yadkin River, the trees are so thick you can just see
the water. It looks so tranquil that the Narrows Dam is a bit of a shock when you turn the
bend.
Rose: “Whoa, this thing’s huge.”
Ellis: “Yeah.” (chuckles)
(sound of climbing out of the truck)
I’m with Gene Ellis, who’s the head of Alcoa Power Generating.
(sound of water falling.)
For nearly 100 years, the aluminum company has owned and operated four dams on one
of North Carolina’s largest rivers. Now Alcoa is trying to renew that hydropower license
for 50 more years. But the Governor of North Carolina wants Alcoa’s dams for herself –
or rather for the people of North Carolina.
The federal law that governs America’s rivers does allow for a takeover, but it’s never
been done. And Alcoa’s Gene Ellis says it’s something he’d expect of a dictator.
“Alcoa’s only experience with the socialization or the nationalization of a plant was
in Venezuela during the leadership of Hugo Chavez.”
Ellis says the takeover attempt violates Alcoa’s property rights. Trouble is that while
Alcoa owns the dams, the people of North Carolina own the river. Alcoa’s basically a
tenant.
And North Carolina Governor Bev Perdue says it’s time to end the lease.
“We need to be sure that the water sources that we are allowing to be controlled – if
you will – by a private industry, produces something for North Carolina.”
Something like jobs, says Perdue, which is why Alcoa built the dams in the first place.
They used to power an aluminum smelter that was the main employer in the region.
In 2002, Alcoa closed the smelter, but still makes millions off the dams. It sells the
hydropower wholesale. Alcoa continues to pay taxes – and still offers free swimming
and fishing on the lakes – but the Governor says that’s not enough to deserve 50 more
years of control on the river.
Officials from at least seven counties agree. As do many residents, like Roger Dick.
“The state needs to be in control. We do not need to be, as citizens, having to go ask
a global company for how we will use our water.”
Ironically, Alcoa’s biggest support comes from towns on the four lakes it manages.
Especially Badin – where you can see the huge, empty smelter from the steps of the
mayor’s office.
Rose: “Did you work there?”
Harrison “Yes. 30 some years. That was our only industry and we’ve lost our heart
when we lost Alcoa.”
And yet, Badin Mayor Jim Harrison says-
“I would rather trust who I know than who I don’t know. Does the state not run our
highways? Do you really think they have done the best with our highways that can
be done? So, I’m mean, if they do the same job with our dams, what’s that gonna
end up being?”
Not even Governor Perdue can answer that yet. Nor is it clear how the transfer would
work or what the state might have to pay for it. Those decisions are up to the Federal
Energy Regulatory Commission, which oversees thousands of hydropower licenses, but
has yet to take one over.
Talking to Mark Robinson – the commission’s director of energy projects – you can
practically hear him scratching his head through the phone line.
“We really can’t figure out what the idea was there. But I’m sure with the help of a
number of very smart lawyers we would all figure it out.”
Since Alcoa expected a decision on its license this summer, lawyers on both sides are
already working overtime.
People across the country are watching closely, because the outcome will set an
important precedent at a time when water is no longer the endless resource many once
thought.

Officials are investigating the
mutilation and death of a green sea turtle
protected under the Endangered Species Act.
Heidi Chang reports, the death of this
particular turtle is causing uproar in Hawaii:
The North Shore of Oahu is a popular gathering place for about 24 Hawaiian
green sea turtles. Residents and visitors from around the world go there
to watch the turtles bask in the sun.
One of the favorites was a 275 pound turtle called ‘Honey Girl’, because
of her honey colored shell.
Joanne Pettigrew is with Malama na Honu. It’s a group of volunteers
that protects the turtles. Pettigrew says the community is outraged over
the killing of Honey Girl earlier this month.
“I was in shock and disbelief, that anyone could remove the breastplate,
cut off the flipper, dismember this beautiful creature, our largest female,
Honey Girl, with a beautiful shell.”
State and federal authorities say they don’t know yet why the turtle was
killed.

A good book has the ability to transport
you to different times and places. You can travel
to far off exotic countries or cities nearby. You
can also visit places that aren’t so easy to get
to – mostly because they don’t really exist anymore.
Places like Hemingway’s wild north woods. Jennifer
Guerra reports:
Say what you want about Ernest Hemingway’s writing, the man loved his North Woods.
Up until his early twenties, he spent almost every summer up north at his family’s cottage
in Michigan.
And it’s there where most of The Nick Adams Stories take place.
“They were walking on the brown forest floor now and it was springy and cool under
their feet. There was no underbrush and the trunks of the trees rose sixty feet high
before there were any branches. It was cool in the shade of the trees and high up in
them Nick could hear the breeze that was rising.”
This is Nick Adams country in the early 1900s. The Last Good Country, Hemingway
called it. Filled with cathedral-like forests and streams swimming with big fat trout.
Now, it’s said that some of The Nick Adams Stories are based on Hemingway’s own
experiences in the north woods. Especially the parts in the book about hunting and
fishing.
“That was one of his favorite things to do.”
Valerie Hemingway was with the author when he wrote The Nick Adams Stories. Before
she married into the family, she was Hemingway’s secretary and occasional fishing
buddy. She says Hemingway used to go on and on about the good old days back in
northern Michigan.
“He taught me how to shoot a gun, told me about the river fishing – and these were
things that were initially associated with Michigan. And I think Michigan
represented the freedom in his life.”
But if Hemingway went up north today, he probably wouldn’t recognize the place.
“I think we’ve done our share of damaging it. And I’m sure there are areas where we
can still find something that he found, but it would be few and far between.”
Mary Crockett just finished The Nick Adams Stories. She read it as part of a state-wide
reading project put on by the local chapter of the National Endowment for the
Humanities. The reason The Nick Adams Stories was chosen for the great state read was
because of its obvious ties to Michigan and the north woods.
But Adam and Eva Colas
just read the book in a high school writing class. They’ve lived in Michigan their entire
lives, and they can’t relate to Hemingway’s North Woods at all.
“It doesn’t feel really representative of Michigan to me, cause it’s not the Michigan I know.”
“Cause even if you go to
Lake Michigan now for camping, there are specific pits for bonfires and specific cabins and all
these designated areas that make sure you don’t get lost or hurt, and you don’t have
to do anything for yourself.”
Their teachers thought that might happen, so they came up with the next best thing. An
outdoor classroom where the students can talk about the stories while doing what Adam
and Eva Colas call ‘the Hemingway thing’.
“The nature, hiking, canoeing. We can’t do the hunting/fishing thing, but just sort
of experiencing nature as nature.”
“Michigan as it was back in the day when this takes
place.”
See, that’s the beauty of a good book. Virginia Murphy teaches a class on Environmental
Literature at the University of Michigan. She says just because the students can’t
experience Hemingway’s world as it was back in the day, doesn’t mean they can’t learn
from his words.
“It allows them to see an environment that they’re not necessarily exposed to on a
daily basis. Most of us live in cities, drive our cars, work in buildings. And so it offers us a
perspective that we don’t have.”
So even if you never got to experience the north woods with all the big open spaces and
virgin forests and clear blue streams, well, there’s always the public library.

Some migratory birds are heading North earlier
because of climate change. That’s causing problems for
some bird species. Lester Graham reports:
On their way north, the migratory birds check things out at each stop along the way. If
the leaves are budding and the days are warm, they keep going north. But because of
climate change they’re getting to their breeding grounds a lot earlier.
Johannes Foufoloupolus is a researcher with the University of Michigan. He says, for
example, in the Rocky Mountain region, robins are arriving early. And when they go to
their highland breeding grounds, there’s still snow on the ground.
“A robin eats worms and it can’t really tunnel through six feet of snow to get to the
worms. So, that might be a problem.”
Other birds arrive early to find one of their main sources of food, insects, are not
emerging yet. What makes it worse, in some species the females like to hook-up with
males who get to the breeding grounds early. But with not as much food and cold
snaps, it means some baby birds are not surviving as well.
For The Environment Report, this is Lester Graham.

One of the Ten Threats to the Great Lakes is changing how the shoreline interacts with
the lakes. Humans like to improve on nature. For example, we like to build things to
protect our property. Protecting a home from forces like wind, water and soil erosion can
be a tough job and expensive sometimes. But if your property is along the shore of a
Great Lake, it can be especially difficult. Reporter Shawn Allee looks at one engineer’s
effort to protect lakefront property and nature:

We’ve been bringing you reports from the series ‘Ten Threats to the Great Lakes.’ Our
guide in the series is Lester Graham. He says the next report looks at protecting property
and protecting nature:
One of the Ten Threats to the Great Lakes is changing how the shoreline interacts with
the lakes. Humans like to improve on nature. For example, we like to build things to
protect our property. Protecting a home from forces like wind, water and soil erosion can
be a tough job and expensive sometimes. But if your property is along the shore of a
Great Lake, it can be especially difficult. Reporter Shawn Allee looks at one engineer’s
effort to protect lakefront property and nature:
Great Lakes shorelines naturally change over time. Beaches erode. Dunes shift.
Sometimes, even the rockiest bluffs collapse.
That’s OK for nature, but maybe not for a house sitting on top of it. So it’s no wonder
that landowners try to stabilize their shorelines. To do that, they sometimes build walls
of steel or concrete to block incoming waves. It’s a tricky process. If the walls are too
short, they won’t stop erosion. But if they’re too long, they trap sand that moves
naturally along the lakeshore.
When nearby beaches can’t get sand, they degrade into muddy or rocky messes.
Charles Shabica is a coastal engineer. He’s been working at the problem for decades
now.
“My dream is to see the shores of the Great Lakes ultimately stabilized, but in a good
way and not a bad way where you’re causing problems.”
Shabica takes me to a small private beach north of Chicago. He engineered it to keep the
shoreline intact. The keys to that are two piles of rock that jut out into the lake.
The piles are just the right size – big enough to protect the shore, but small enough to let
some sand pass by. There’re other elements to the design as well.
Tall, blue-green grasses line the beach’s perimeter.
“Not only do waves tend to move sand around, but wind is also really an important agent,
too. So the beach grass and dune grass tends to stabilize the sand. And what will happen
is, you can see these things are seeding now, wind will blow the seeds and pretty soon
you get that stuff growing all over the place.”
A lot of homeowners and city planners applaud Shabica’s work. But not everyone does.
Some environmental groups say, once a landowner builds a wall or rock formation,
others have to follow suit, just to preserve their own sandy shoreline.
The environmental groups’ alternative? Keep development farther away from shorelines
and allow more natural erosion.
But that hands-off approach is not likely to happen. The majority of Great Lakes
shoreline is privately owned. And in many states, landowners often prevail in court when
they try to protect their investments.
Keith Schneider of the Michigan Land Use Institute says the question isn’t whether to
build near the shore, but how to do it.
He says, in the past, landowners tried to get off cheap. They didn’t pay for quality
construction or get expert advice on local geological systems.
“If you don’t pay a lot of attention to these systems, it’s gonna cost you a lot of money.
And if you build inappropriate structures or inappropriate recreational facilities, you’re
going to either be paying a lot of money to sustain them or you’re gonna lose them.”
A lot of coastal geologists agree that, for much of the Great Lakes coast, private
shoreline protection efforts – even the bad ones – are here to stay.
In urban or suburban areas, housing developments near the shore often include a buffer or
wall.
Michael Chrzastowski is with Illinois’ Geological Survey. He says, in these cases, the
shore can look natural…
“But it’s going to be a managed, engineered facility, because wherever you are on the
shore, you’re influenced by some other construction or historical development along the
shore that’s altered the processes where you are.”
That’s definitely the case along highly-developed, urban coastlines, such as Illinois’.
Other parts of the region are catching up, though.
“What’s going to happen is, other places along the great lakes as they become more
developed and they become more urbanized, they’re going to use Illinois as a model.”
That could bring more projects like Charles Shabica’s little beach. Shabica says that’s
not necessarily a bad thing.
It’s just a way to come to terms with our presence along the lakes.
“Human beings are here to stay. It’s our responsibility I think to make our environment
better for us, but not at the expense of the biological community, and your neighbors.”
That sounds reasonable enough. But it will ultimately mean the vast, natural coastlines of
the Great Lakes will be engineered, one beach at a time.

Scientists from around the world are studying how higher levels of carbon dioxide will affect forests 100 years from now. They’re doing that by pumping higher levels of CO2 and ozone into stands of trees. The Great Lakes Radio Consortium’s Mike Simonson visited the experimental forests and has this story:
(sound of “quiet area”)
The north woods of the Great Lakes states are stands of millions of acres of pine, maple, birch, and aspen forests. It’s a perfect place to try to figure out how trees will react to the higher levels of ozone and carbon dioxide scientists expect in the future.
(sound of beeping fence gate)
The first thing you notice at Aspen Free Air Carbon Dioxide Enrichment Project – Aspen FACE for short – is two huge tanks inside the fenced in enclosure. Each one is bigger than an 18-wheel tanker truck. They’re full of carbon dioxide… CO2. So much CO2 is used in this experiment, the tanks are filled twice a day.
(sound of filling tanks)
If you looked at the site from an airplane, you’d see 12 circular tree stands surrounded by 30 foot high pipes. Those pipes pour CO2 or ozone gases or both into the air surrounding birch, sugar maple, and aspen trees. The scientists know that greenhouse gases in the earth’s atmosphere have been increasing. They believe two centuries of industrial pollution has contributed to the problem. And they expect the CO2 and ozone levels to double by the end of this century. They’re raising the level of greenhouse gasses in different mixes to see what the predicted levels will do to forests.
This open air project is different than previous experiments. David Karnosky is with Michigan Tech. He’s the Project Manager for Aspen FACE. He says before these kinds of projects, they just tested trees inside places like greenhouses.
“We needed to get out of those chambers. We needed to have a more realistic, real world sort of situation where we had multiple trees. We wanted real intact forest communities. We didn’t want to have just a small number of trees inside of a chamber.”
The United States Department of Energy launched this experiment in Wisconsin’s northwoods seven years ago. Karnosky says they’re learning how the trees react to the higher CO2 levels, and that could shape the future of the world’s timber industry.
“Who will be the winners? Who will be the losers? Will aspen or birch or sugar maple? In northern Wisconsin here we’ve got probably 40 million acres of those species mixes. What’s going to happen under elevated CO2 in the next 100 years? Will these forests remain as they are?”
(sound of driving on gravel)
Driving to one of the experimental circles, we pull up to a ring of trees. Mark Kubiske is one of the two full-time on-site researchers.
“Now this particular ring is an elevated CO2 plot. CO2 is delivered through this copper pipe. It runs to that fan, there’s a large fan right on the end of that gray building.”
The scientists have found that trees in the CO2 circles grow 30 percent faster than trees without the gas.
“The trees are larger in diameter, they’re straight, they have lots of leaf area, they just look very healthy. That is just in tremendous contrast to the ozone ring. We’ll go up around the corner and look at one.”
Nearby another circle of trees is not doing nearly as well. The trees are skinny, twisted not as tall as the other sites. Higher ozone levels are hurting the trees.
At the sites where pipes emit both ozone and CO2, the tree growth seems normal – except for some stunted maple trees. The leaves of the aspen and birch take in much of the CO2, convert it to sugar which goes to its roots, eventually becoming a natural part of the soil. That suggests forests may help alleviate gases that cause global warming. The Project Director, David Karnosky says CO2 and ozone appear to cancel each other out. But he says it’s too early to draw any firm conclusions. Ultimately, he says governments will be able to look at this glimpse into the future and try to come up with emissions policies that help.
“The whole issue of the Kyoto protocol, our government not signing off on that. There’s been some relaxing of the feelings from what I’ve seen from the President’s report now that they’re beginning to realize that elevated CO2 is having an impact on global warming and could be impacting our plant communities.”
Karnosky says it’s possible that besides reducing emissions, governments might determine that planting more trees might be very helpful in reducing greenhouse gasses worldwide.
