Environmental groups say it would make financial sense for chemical
plants that emit a lot of mercury pollution to go mercury-free. Chuck Quirmbach
reports:


Environmentalists have been zeroing in on businesses that use mercury to make
chlorine for industrial processes. In many cases, the mercury escapes into the
atmosphere and eventually gets into the food chain. Some chlorine producers
have switched to mercury-free technology, but a report by the group Oceana
zeroes in on five US plants that haven’t made the change.


Oceana spokesperson Eric Uram admits going mercury-free can cost tens of
millions of dollars. But he says the firms can often save money on energy:


“Which they can either pass on to their shareholders or they can increase their
profitability.”


But the manager of one chlorine plant says the amount of money needed to
make the change has her corporate headquarters proceeding cautiously.

An oil refinery is expanding in part to meet growing demand for gasoline. The
refinery planned to dump more waste into the Great Lakes. Laura Weber reports
the refinery company is now delaying those plans:


British Petroleum plans to expand its Indiana refinery near Lake Michigan.
State and federal authorities have given BP permission to dump more ammonia
and sludge into the lake.


This is the first time a company has been allowed to dump more pollution into the
Great Lakes since the Clean Water Act was passed in 1977.


But BP is putting its plans on hold after meeting with Congressional leaders.
US Senator Debbie Stabenow says Congress wants to make sure BP will dump the
least amount of waste possible:


“There is a real question in my mind, particularly, when we’re talking about a Great
Lake that’s impacted by a variety of state actions. I think this is an important thing
to look at.”


The expansion plans are delayed until September. A BP spokesman says if there is
additional dumping, it will not harm the Great Lakes ecosystem.

Yellow Cabs Turning Green?

Taxi cabs represent only a small portion of the cars on city
streets. But they’re on the road for long periods of time. As Brad Linder
reports, that’s why some cities are looking at battery powered cabs as
a way to reduce vehicle emissions:


The typical New York taxi cab is on the streets for 10 hours at a time.
Earlier this year, the city’s Taxi and Limousine Commission wanted to
see if an electric vehicle could make it through an entire shift. But
the test cab from manufacturer Hybrid Technologies rarely made it
through half a shift before running out of juice.


Commission spokesman Allan Fromberg says that’s just not good enough:


“It was unfortunately not possible to do that. When
you’re getting 40 miles and you know, the average shift would probably
take a taxi cab about a hundred miles.”


Fromberg says there are more than 13,000 gasoline and hybrid electric
cabs in New York right now. He says the city would be interested in
approving a 100% battery-powered cab as long as it can
survive a regular taxi shift.

Nature Profile: Nature & the City

Big cities have skyscrapers, smelly subway stations,

Big cities have skyscrapers, smelly subway stations,
and people from all over the world. In our
occasional series about people’s connections to the
environment, Kyle Norris talks with one big city
resident who says that the people and places of New
York City connect her to the world:


Audra Brecher wears her chestnut hair in a Louise
Brooks bob. Actually, she’s a dead ringer for Louise Brooks,
that silent film movie star. She’s stylish
and snazzy.


Audra lives in Manhattan. Her apartment is above a
pizza parlor on a bustling avenue. She says in the
evenings, she hears blaring taxi horns and the thumping
techno music from the clubs on her block. But she
loves everything about the city: its sounds,
its architecture, and its people.


I once asked her if she ever missed nature. She said,
“The city lights are my stars.”


“Yeah, I don’t feel as if I’m missing anything. I don’t
feel maybe such a romantic feeling about stars, the
night sky. I feel maybe the same excitement when I
see the city lights and when I walk across Lexington
and I look north and I see the Chrysler Building lit
up and those beautiful, starry chevrons of the
Chrysler Building. I think maybe the feeling I have
looking at that, is what other people feel when they
look at the night sky.”


So here’s the deal. When I think of someone connected
to nature I picture a state park ranger. I picture a crunchy-
granola type. I do not think of someone who wears
fashionable clothes and wines and dines in the city. I
do not think of Audra. But Audra says she has a
better connection to the natural world than people in the
suburbs:


“I go to the Union Square market on Saturday and I
buy varieties of apple that have come from the
Hudson River Valley and I know my parents, who
live in the suburbs in Florida, they go to the grocery store
where they buy everything pre-packaged and already
cut up fruit. I feel like my experience is actually closer to
nature even though I’m in heart of Manhattan.”


Audra works in an architecture firm. She’s a historic
preservationist, and she’s studied architecture all over the
world. But she grew up in the Florida suburbs. And
what she saw there – the sprawl and development –
seemed wrong to her:


“What led me to do what I do is noticing how
unhappy I was with a suburban existence. Having to
get in car to drive somewhere, or looking at
expanses of parking lot in strip centers and
subdivisions with gated communities that are named after
the natural feature they replace. Like ‘Eagle’s Nest.'”


Those new developments seem wasteful to her. She
likes the idea of re-using materials. And this
connects her to nature. At her job, she’s always in
close contact with old buildings and old materials:


“Yeah, I love the materiality of them. I mean, I love
an old brick from 120 years ago. I love the building
materials and the craftsmanship from that time. I
love the idea of taking something that has been cast
aside and might not be used and giving it a new
purpose, giving it a new vitality. Taking a building that
somebody has abandoned and giving it a new life.
To me, that’s the ultimate recycling.”


Audra says although she’s not walking through the
forest and communing with nature, she feels
ecologically responsible in different ways. She either walks or takes public transportation to get someplace. She never drives a car.


“I’m not asking so much of the world in terms of
water and energy and resources and I feel like when
live in dense environment you are allowing for those
things to remain protected and safe. And pristine. So
I feel like a responsible citizen living in Manhattan
in many ways.”


This stylish city-slicker may not be the person
who pops in your head when you think of someone who’s connected to nature. But Audra’s
deeply connected to the world around her in her own way. She’s also aware of how we can use natural
resources in better ways.

Ethanol Part 2: Widening the Dead Zone?

  • Farmer Laura Krouse says the ethanol boom has been great for corn farmers, who she says are finally getting a fair price for their corn. But she says she's worried that there's not enough being done fast enough to reduce the dead zone in the Gulf of Mexico. (Photo by Rebecca Williams)

Scientists are predicting the Dead Zone in the Gulf of Mexico will reach its largest size ever this summer. Fish and shrimp can’t survive in the Dead Zone. It’s believed to be mainly caused by fertilizer washed from farm fields across the nation.

Scientists are predicting the dead zone in the Gulf of Mexico will reach its largest size ever this summer. Fish and shrimp can’t survive in the dead zone. It’s believed to be mainly caused by fertilizer washed from farm fields across the nation. Rebecca Williams reports some scientists say demand for ethanol made from corn could make the dead zone even bigger:


(Sound of tractor raking hay)


“It’s the perfect Iowa day, you know?”


Laura Krouse is tearing apart a bale of hay to mulch her tomatoes.
She’s a thousand miles from the Gulf of Mexico. But she points out,
what happens on farms here ends up affecting life way down South:


“This watershed I live in drains 25% of Iowa. And we’re one of the
richest farming states in the nation – of course we have something to
do with it.”


By “it,” Krouse means the dead zone. All or parts of 31 farm states
drain into the Mississippi River, which empties into the Gulf.
Scientists point to nitrogen fertilizer used on farm fields as the main
cause of the dead zone. All that nitrogen causes an enormous algae
bloom. When the algae dies it drops to the ocean floor. Bacteria eat
the algae and they rob the water of oxygen.


This summer, the dead zone’s predicted to reach a record size. It could get as big as the state of New Jersey.


Laura Krouse has been trying to cut back her own role in the dead zone.
Five years ago, she added something to her farm that’s rare around here.
Krouse cut some of the tile lines that drain water from her farm, and
replaced part of her farmland with a prairie wetland. She says that
made her neighbors nervous:


“We just don’t see people taking land out of production in Iowa very
frequently.”


Wetlands like this one remove nitrogen from the water that flows from
farm fields.


It’s one of the things a government task force on the dead zone
recommended to cut nitrogen loading into the Gulf.


But instead of a big push to restore wetlands, the economic landscape
is changing in the other direction. Demand for ethanol has led to
historically high corn prices. And that’s encouraging farmers to grow
more corn. A USDA report says farmers have planted 14 million more
acres of corn this year than last year. It’s the most corn planted in
the U.S. in more than 50 years.


Laura Krouse says this is not good for the Gulf of Mexico:


“I’m concerned about all the extra corn because it requires nitrogen to
produce that corn and no matter how careful we are and no matter how
expensive it is which causes us to be more and more careful with
application, nitrogen as a molecule just wants to get away. It is
leaky.”


When it rains, nitrogen runs quickly from farm fields and gets into
creeks and rivers. The federal government’s task force on the dead zone has been trying to
tackle all this.


Don Scavia led a group of scientists advising the task force under the
Clinton Administration. The Bush Administration convened a new science
panel to review the original science panel’s work. Don Scavia says
since then, there’s been very little progress in shrinking the dead
zone, or what scientists call an area of hypoxia:


“In fact what we’ve seen in the last year is just the opposite with
this push towards corn-based ethanol production. Even acres that were
set aside into conservation are coming back out into production, into
corn, and the increased nitrogen load to the Gulf this year and the projected record
hypoxia is probably caused by this increased corn production.”


Scavia says if the dead zone keeps increasing, the Gulf shrimping
industry could collapse.


Ironically, the new science panel appointed by the Bush White House is
calling for even bigger cuts in nitrogen than the first panel appointed
by the Clinton Administration. They want to reduce nitrogen from farm
fields and other sources by 40 to 45 percent.


Don Parrish is with the American Farm Bureau. He says those reductions
are too much:


“Those are going to be really difficult and they could cause
significant economic dislocation at a time when I think we need to be
thinking about the products that agriculture produces, and those are
important.”


There’s no question corn for ethanol is at the top of that list right
now. Ethanol’s popular. It’s making farmers richer. It’s making the
chemical companies that supply nitrogen richer. The government task
force has to figure out how to cut back on all the nitrogen that’s
needed to grow all the corn… that’s needed for billions of gallons of
ethanol.

Ethanol Part 1: Running the Well Dry?

  • Ethanol is starting to bring prosperity to some rural communities. But there are also concerns about whether adding this new industry to other industries - and cities - that draw on groundwater supplies will cause local shortages of water. (Photo by Rebecca Williams)

It’s no surprise that the Corn Belt is the heart of the ethanol boom.
Two main ingredients you need to make ethanol are corn and water.
There’s no shortage of corn of course, and in most places it’s assumed
there’s also plenty of water. But as Rebecca Williams reports, even
people in water-rich states are getting concerned about ethanol’s
thirst for groundwater:

It’s no surprise that the Corn Belt is the heart of the ethanol boom.
Two main ingredients you need to make ethanol are corn and water.
There’s no shortage of corn of course, and in most places it’s assumed
there’s also plenty of water. But as Rebecca Williams reports, even
people in water-rich states are getting concerned about ethanol’s
thirst for groundwater:


Bob Libra can tell a lot about water by looking at rocks. We’re in his
rock library – it even has a Dewey decimal system. Libra’s holding up
one of the 35,000 chunks of rock in here.


(Sound of scraping on limestone core)


“This for example is a core from a well. You can look at this and say well this is
what the plumbing system’s like down there.”


Libra’s a state geologist with the Iowa Department of Natural
Resources. Part of his job is to figure out how healthy his state’s
water supplies are. Any time a test well is drilled for a new ethanol
plant, rock samples get sent here.


Outside the rock library, there are three red pipes sticking up out of
the ground. These are observation wells that tap into sources of
groundwater far underground, called deep aquifers:


“A lot of people refer to it as Paleo-water or fossil water. It’s been
down there tens of thousands, hundreds of thousands, maybe millions of
years.”


Libra says the water in those deep aquifers is pumped out for
everything from drinking water to ethanol plants. But as it’s pumped
out, it’s not replaced right away. It could take hundreds or thousands
of years to replenish the aquifers.


Geologists use the observation wells and rock samples to figure out how
much water is in those aquifers. But here at the rock library, those
samples are piling up into small mountains in the storage room. Bob
Libra says his state is way behind. Iowa hasn’t updated its groundwater
maps for 20 years:


“I think Iowa’s in the same kind of situation that a lot of states that
tend not to think of themselves as ‘water poor’ are finding themselves.
We haven’t paid attention to it for 20 years and suddenly BANG we’re
using an awful lot. And we have people every day going I’m interested
in putting a plant here – how much water can I get over here? And it’s
happening very rapidly.”


Each state has its own way of managing its groundwater. In Iowa, you
have to have a permit if you’re withdrawing more than 25,000 gallons of
water per day from a well or stream. Libra says the ethanol boom has
overwhelmed the state office where permits are handed out for the
asking:


“I’m at this location, I’m drilling into this aquifer, I’m going
to extract this amount of water. Here’s my $25 for a 10-year permit.”


Libra says nobody’s really checking to see if all these water
withdrawals will work for the next few decades.


How much water ethanol plants consume depends on who you talk to. But
on average, it takes between three and four gallons of water to make
one gallon of ethanol. Bob Libra says here in Iowa, adding new ethanol
plants is like adding a bunch of new towns out in the cornfields:


“A lot of ethanol plants they’re building now are on the order of 100
million gallon per year capacity so they’d be using about 400 million
gallons of water a year which is roughly as much as a town of 10,000
people.”


In some drier states, new ethanol plants are running into opposition.
Mark Muller is with the Institute of Agriculture and Trade Policy. He
says groundwater is local. So, what works in one place might be a
crisis in another:


“We’ve already seen it in Southwest Minnesota where a plant was denied because
of a lack of water resources. There’s a couple big fights going on in
Kansas right now over water availability. I think this is going to
probably one of the big drivers that’s going to make the industry look
further East rather than in the Midwest/Great Plains.”


The ethanol industry argues that it has already cut back on water use.
Lucy Norton is the managing director of the Iowa Renewable Fuels
Association. She says it’s in the industry’s best interest to be
careful with water:


“We’re not going to see a plant built somewhere where it’s an iffy
situation as to whether 10 years from now we’re going to have enough
water. You don’t put $200 million investment into a location that’s
not going to be able to sustain itself 10 years from now.”


But even if the water supplies could last 50 years, once the water is
gone from the aquifers, it’s gone for a long time.


There are a lot of
test wells going in these days, with 123 plants in operation and more
than 80 under construction around the country.


The growing political pressure for more and more ethanol is making
state officials eager to figure out exactly what’s underground, instead
of just assuming there’s enough water.

A toxin that has killed tens of thousands of shorebirds throughout
the Great Lakes is back. Type E botulism is spread up the food
chain by invasive species. And as Bob Allen reports, the toxin
recently killed four birds on the endangered species list:


There are just 60 pairs of piping plovers known in the Great
Lakes. Many of them breed along the shores of Lake Michigan.


Wildlife officials protect nesting plovers by putting up fences to
keep predators away, but they can’t keep the tiny shorebirds from
eating insects as they skitter up and down the beach. The insects
can pass on Type E botulism to the endangered birds.


Biologist Ken Hyde says the toxin gets into the food chain
through fish – primarily round gobies – that feed on algae and the
invasive zebra and quagga mussels.


“Yeah, we’ve got some pretty good evidence that it’s this cycle of
the algae and then the mussels and the gobies feeding on them
and then primarily gobies coming to the surface that our native
water birds are feeding on.”


Wildlife officials expect to see a lot more dead shorebirds as
the summer progresses.


Type E botulism is not a threat to humans.

Discouraging Bottled Water

Over the last six years, bottled water consumption has gone up 60
percent in the United States. That means a lot of plastic bottles are
being thrown out. As Brad Linder reports, businesses and local
governments across the country are trying to encourage people to cut
back on bottled water:


Environmentally-conscious restaurants around the country have begun
removing bottled water from their menus. And the city of New York has
launched a new advertising campaign to convince citizens to drink tap
water. They tout it as “fat-free,” and “delicious.”


Susan Neely is the president of the American Beverage Association. She
says these campaigns miss the point:


“We need clean, accessible, safe tap water. But there’s great advantages
to bottled water, too. It’s portable, it’s convenient. And we can more
easily do what doctors and nutritionists are telling us to do, which is to drink more
water, particularly in these hot summer months.”


Neely says plastic bottles make up only one third of one percent of the
nation’s waste, and that’s not including the bottles that are recycled.


But not every bottle gets recycled. And it takes both energy and
petroleum to produce and distributed bottled water. That’s why cities
like New York are promoting tap water as an environmentally-friendly
alternative.

Report: Ethanol Not the Answer

Using corn to make fuel for cars and trucks will cause more pollution, higher food prices,
and will not greatly reduce the country’s dependence on foreign oil. That’s according to a
recent report by several environmental groups. Mark Brush has more:


About 20% of this year’s crop in the US will go into making ethanol. That’s expected to jump to 27% next year. The push for more corn-based ethanol has already led to higher food prices. A new report
says if the ethanol trend continues unchecked – it will cause more fertilizer pollution in
water – and more air pollution from ethanol processing plants powered by coal and
natural gas.


Dulce Fernandez is with the Network for New Energy Solutions – one of the groups that
put out the report. She says ethanol is not the answer:


“I think everybody is looking for one great solution to solve all of these problems. But
nobody is thinking about the great potential that is out there to reduce demands.”


Fernandez says the best way to reduce demands is for the federal government to raise fuel
economy standards, instead of subsidizing corn-based ethanol.

Saving Historic City Parks

  • In October 2006, a surprise snow storm did considerable damage to the trees in the Olmsted Park System. (Photo by Joyce Kryszak)

At one time, cities were little more than stone and brick. But in the mid-1800’s
Frederick Law Olmsted began changing all that. The landscape architect

At one time, cities were little more than stone and brick. But in the mid-1800’s
Frederick Law Olmsted began changing all that. The landscape architect
designed some of the most important park systems in the country. But decades
of neglect and nature’s wrath are threatening Olmsted’s largest park system.
Joyce Kryszak has the story of plans to restore it:


You’ve no doubt heard of, and maybe even taken a stroll through New York’s
Central Park. It was Olmsted who created that 800 plus acres of sprawling urban
backyard. But Olmsted didn’t just carve out a magnificent green space. He also
carved out a reputation for himself, and a demand for his designs for parks all
over the country. Olmsted’s green thumb-print can be found all the way from
Boston’s Emerald Necklace to Yosemite National Park. Brian Dold is a
landscape architect from Buffalo, New York. He says even his profession is an Olmsted
creation.


“[He] came up with the term landscape architecture and really brought it to a
scale where he could do these major projects. So, he sort of grew
from getting work and the profession sort of took off from there.”


And Dold has plenty of work to do in Buffalo, New York. There, he is
maintaining Olmsted’s first, and one of his largest, integrated park systems.


Last October, a surprise snow storm dumped two feet of heavy snow on the still
leaf-covered boughs of Olmsted’s majestic trees. Many of them splintered under the
weight, leaving an amputated landscape. Ninety percent of the trees were
damaged and hundreds were lost. But devoted park lovers are volunteering to help
the non-profit conservancy plant new trees throughout the six parks and
parkway.


“Woo, that’s a lot of work. All right, you got it.”


John Penfold even climbs up on top of the shoulders of other volunteers to unlash the
branches of a newly planted maple. Penfold says they’re willing to do whatever it
takes to save the parks.


“When the storm hit, kind of saw all the trees fall, so, I think it brought the
community together to realize, we have these trees and we need ’em.”


Before the storm hit, the park system was already in crisis. American Elm
disease swept through, killing the stately trees. Then the city cut money for
maintenance. But now, the non-profit conservancy has come up with a twenty-
year master plan to restore the Olmsted park system. Executive Director
Johnathon Holifield says they have their work cut out for them:


“This system, at one time, was home to about 40,000 trees – 40,000. We’re
down to about 12,000,” said Holifield. “So, we have a long way to go to
truly recapture the Olmstedian glory.”


The sense of urgency is helping the conservancy raise the money and muscle
needs to fully restore Olmsted’s vision. The vision part is where landscape
architect Brian Dold comes in. Dold poured over Olmsted’s plans and he consulted
with other conservancies. It’s his job to make sure that the system returns to the
naturalistic setting Olmsted intended.


“He really tried to make it look like it had naturally occurred. He used like
large open meadows, and dense woodland and pathways through there,
sort of meandering through, sort of creating that Olmstedian landscape
that looks like it could have been there from the beginning of time.”


But Olmsted’s plan will get tweaked a bit. Dold says had some experiments that
didn’t work out so well. Over time, the Norway maples and the Common Buckthorn
trees pretty much took over. Dold says they won’t repeat the mistake:


“We’re not planting any of those trees that aren’t zone hardy and trees that
are put on invasive species lists. Those are pretty much eliminated from
anything we would ever do in these parks. And we are actually
physically removing many of them.”


Instead, Dold says they’ll plant native species. Lots of sugar and red maples,
service berries, eastern redbud and others. 28,000 trees over the next 20 years.
Executive Director Johnathan Holifield believes the new plan would meet
Olmsted’s approval:


“He would be pretty happy and particularly when you look out there and
you see the diversity of use in the park, the volunteer element that we
have. That’s what Olmsted was about – democratic,
egalitarian use and that certainly is represented today.”


So, if you happen to be in a Buffalo Olmsted park this summer, be sure to bring a
picnic basket and blanket, or maybe a shovel and some tree stakes.
