Acidic Oceans Dissolving Shellfish Industry

When carbon dioxide is released into the atmosphere, about a third of it absorbs into the ocean. That creates carbonic acid—the stuff in soda pop that gives it that zing.

That means seawater is becoming more acidic.

Scientists say this ocean acidification is starting to cause big problems for marine life. And Ann Dornfeld reports that could affect your dinner plans.

Taylor Shellfish Farms has been growing oysters for more than a
century. And shucking them, one by one, by hand.

“An old profession. Y’know, they’ve tried for years to
find a way to mechanize it. There’s no way around it. Every oyster is
so unique in its size and shape.”

Bill Dewey is a spokesman for Taylor. The company is based in
Washington state. It’s one of the nation’s main producers of farmed
shellfish. Dewey says if you order oyster shooters in Chicago, or just
about anywhere else, there’s a good chance they came from Taylor.

But in the past couple of years, the company has had a hard time
producing juvenile oysters – called “seed.”

“Last year our oyster larvae production was off about 60
percent. This year it was off almost 80 percent. It’s a huge impact to
our company and to all the people that we sell seed to.”

Shellfish growers throughout the Pacific Northwest are having similar
problems with other kinds of oysters, and mussels, too. They suspect a
lot of it has to do with ocean acidification.

Richard Feely is a chemical oceanographer with the National Oceanic
and Atmospheric Administration. He says when the pH of seawater drops
too low, it can hurt marine life.

“What we know for sure is that those organisms that
produce calcium carbonate shells such as lobsters, and clams and
oysters, and coral skeletons, they generally tend to decrease their
rate of formation of their skeletons.”

Feely says it looks like acidified waters are affecting oysters
because their larvae build shells with a type of calcium carbonate,
called aragonite, which dissolves more easily in corrosive water.

The more acidic seawater also encourages the growth of a type of
bacterium that kills oyster larvae.

Feely says the changes in the ocean’s pH are becoming serious. He
recently co-published a study on the results of a 2006 research cruise
between Hawaii and Alaska. It was identical to a trip the researchers
took in 1991. They found that in just 15 years, the ocean had become
five to six percent more acidic as a result of man-made CO2.

“If you think about it, a change of 5% in 15 years is a
fairly dramatic change. and it’s certainly humbling to see that in my
lifetime I can actually measure these changes on a global scale. These
are very significant changes.”

A couple years ago, Feely gave a talk at a conference of shellfish
growers. He explained the impact ocean acidification could have on
their industry. Bill Dewey with Taylor Shellfish Farms was there.

“All these growers were walking around with all these
really long faces, just very depressed. I mean it was a very eye-opening presentation and something that’s definitely had growers
paying attention since, that this could be a very fundamental problem
that we’re going to be facing for a long time to come.”

Dewey calls shellfish growers the “canary in the coalmine” for ocean
acidification.

Scientists say if humans don’t slow our release of CO2 into the
atmosphere, shellfish may move from restaurant menus into history
books.

Farmers are finding they can
make more money selling crops
for energy than for food. A third
of all corn grown in the US gets
turned into ethanol. It’s tough
to balance the need for energy
and food when millions around
the world die from starvation each
year. Still, farmers are reconsidering
their roles – including in Germany.
In the second part of our three-part
series on biofuels in Europe, Sadie
Babits meets with one German
farmer who wants to make the switch
and become an energy farmer:

Erhard Thale jokes a lot about being an organic farmer. It’s about all he can do.

“He has like his corn harvest from two years ago is still lying down on his farm so it’s not sold on the market.”

It’s hard to imagine. We’re outside Ludwigsfelde not too far from Berlin. Thale’s land looks green and healthy – not bad for late fall. But looks can be deceiving. Thale says he’s lost money for the past three years. He blames his land and a volatile world market.

“Then My wife comes and asks, ‘where do we go from here? Piggybank is empty. Money gone.’”

Thale says he can make more money selling his organic corn and rye for energy instead of food. He’s not joking around. There’s a growing movement in Germany to get farmers like Thale to set some of their land aside to grow grains just for energy. There are now areas throughout the country developing so called “bio-energy regions.” The idea is that a community like Ludwigsfelde would produce its energy locally.

Farmers like Thale would sell their grains and manure to a regional bio-energy power plant. Those materials would get turned into green energy. The 20,000 residents who live here wouldn’t have to rely on fossil fuels and they’d cut down on greenhouse gas emissions. Sounds promising. But Thale says he’d build his own plant if he had three million dollars. Then he could keep all the profits from selling energy.

“He needs an uncle in the U.S. with two million euros.” (laughter)

Other farmers, though, are cashing in, finding money in, well, poop.

(sound of milking machine)

A cow chews her cud as an automatic machine does the milking. This milking parlor is part of an agricultural training center here in west central Germany. This is the greenest farm I’ve been on. There’s a bio-energy power plant. Wind turbines and solar arrays.

Klaus Wagner runs the center. He says this cow’s manure is more valuable than the milk.

“That can’t be.”

Wagner sees a growing rivalry between dairy farmers who want to sell milk and those who want to sell manure for biogas.

“I guess that the milk and energy production on the other side belongs together. And those farmers who built 3-4 years ago biogas plant they earn real money now. The biogas plant substitutes the milking production.”

It really comes down to a question of sustainability. How much land here in Germany and, for that matter, the U.S. should be set aside for making energy? It’s not an easy answer. In the long run, if farmers grow grains for energy instead of food, that will impact the food supply and eventually what we pay at the grocery store.

Going Renewable Voluntarily

The market for renewable solar
and wind power is growing quickly.
Most people assume that growth
has been mandated by government.
But Shawn Allee found
a report that challenges that:

The report’s from the Center for Resource Solutions, an advocacy group.

Orrin Cook was a co-author. He totaled up growth in sales of wind, solar and other renewable energy between 2003 and 2008. He compared how much growth came from government mandates and how much was bought voluntarily. Cook says the voluntary market grew a tad faster.

“States requiring renewable energy and federal government requiring renewable energy is really just part of that equation. Another part is businesses and individuals buying renewable energy when they don’t have to.”

Cook says this voluntary renewable energy market grew because some companies have eco-minded managers. But he says companies also bought renewable power because customers pushed them to.

Cook looked at federal figures that came out before the financial crisis.

Sparring Over Water in the South

It’s called “the economic engine of
the South.” Atlanta, Georgia’s population
has exploded in the last two decades.
But with that growth has come environmental
problems, like where to get enough drinking
water. Georgia, Florida, and Alabama
have been fighting over who gets how
much water from rivers that flow through
the states. And, as Tanya Ott reports, a
decision in the federal lawsuit could effect
communities across the country:

Atlanta draws millions of gallons of drinking water each day from nearby Lake Lanier. But Alabama and Florida say it’s such a water hog, there might not be enough water sent on downstream to cool power plants or protect the seafood industry.

“I had no idea! (laughs) I didn’t really realize there was a problem.”

Atlanta-area resident Connie Brand says she knew the state was in a drought last year. She knew she was supposed to conserve water, and she did.

“Not taking such a long shower; not doing small loads of laundry.”

But only recently did she realize how big a problem this could be.

In July, federal Judge Paul Magnuson ruled that under the law Lake Lanier was intended only for things like navigation and flood control – not drinking water. He said if Florida, Georgia and Alabama don’t come to a water agreement by 2012, Atlanta has to stop taking drinking water from Lake Lanier.

“The action of a court could create a public health emergency that would probably rival the effects of Katrina.”

That’s Charles Krautler. He’s director of the Atlanta Regional Commission. He says in the past 25 years Atlanta’s population has more than doubled to 4 million residents and there’s no way to get water to people without Lake Lanier.

“How do you decide who doesn’t have water and who does? Our chairman likes to say, ‘FEMA doesn’t have enough trucks to bring in enough bottled water to deal with the shortfall that would exist.’”

It’s not just an issue for Atlanta. There are more than two dozen similar reservoirs around the country. They were built for navigation, flood control or hydropower. But communities are using them for drinking water. Congress might have to step in to basically retro-actively approve the drinking water use. Cindy Lowery is executive director of the Alabama Rivers Alliance.

“If it goes to Congress, which the court case says that it might have to, it could get even more political and more chaotic really.”

Several members of Congress have said they won’t act until Florida, Georgia and Alabama come to a deal. But Lowery says, so far, the negotiations have been dominated by government agencies and special interests like power companies. She wants a panel of neutral advisors and scientists to study the issue.

In the meantime, Atlanta residents like Connie Brand are left wondering what will happen.

“I’m from a family when they grew up they relied on cistern water, and when it rained you had water, and when it didn’t rain, you didn’t have water. So I’m familiar with having to ration and be careful about those kinds of things. But I don’t think my child or people of my generation, their children, have any concept of conservation of water or anything like that.”

Brand says she just might have to step up her own conservation efforts.

“What was it we had in college? If it’s yellow let it mellow, if it’s brown flush it down? (laughs) that’ll be our new motto! (laughs)”

CO2 Helps Trees Grow Faster

Climate change means faster growing
trees. Kyle Norris looks at ongoing
research that’s looking at how that
plays out:

Maybe you remember this from grade-school science: trees take in carbon
dioxide—that’s a gas emitted from burning fossil fuels. Then trees convert that
CO2 into oxygen. So with more carbon dioxide, trees are really taking off.

Wendy Jones is a research associate. She’s with Michigan Technological
University and she’s been studying young trees for the past eleven years.

Not only does carbon dioxide make trees grow faster, but warmer temperatures
help prolong the growing season. Jones says that could be good for the timber
industry.

“We could cut the trees sooner because they’re growing faster.”

For example, fast-growing aspen trees are used in everything from paper to
matchsticks. Jones says climate change could mean aspens could be harvested in
25 years instead of 35 years.

A Hidden Danger in the Garden

All over the country, first-time
gardeners are harvesting their ripe
tomatoes and leafy greens. Gardening –
especially in cities – is thriving.
But Karen Kelly reports on a hidden
danger that isn’t always easy to detect:

(sound of little girl in garden)

It’s our first vegetable garden and my daughter and I are looking for some ripe veggies to have for dinner.

It was the highlight of our summer – planting the cucumbers and the eggplant and watching the tomato vines grow higher and higher until we couldn’t even reach the top.

Then I read a story that they had discovered lead in the White House vegetable garden. Exposure to too much lead can cause brain damage, especially in children. And as I read the description of the type of yard that would likely contain lead, I realized that our garden met all of the criteria.

We live in a house more than 50 years old. It’s in an older neighborhood that would have been exposed to residue from leaded gasoline. And we live in a fairly large city -Ottawa, Canada – near a busy road.

So I decided to get our soil tested for lead.

(sound of phone call)

I started by calling the city and other government agencies– no luck. I tried looking for labs in the yellow pages. Those didn’t work out. I moved on to garden centers, a local university, and a local research farm. No one could talk to me.

Finally, I got in touch with a lead expert in Indianapolis, Indiana. He asked me to send him some samples in plastic lunch bags.

“Okay, I just scraped off a place with no wood chips. Okay, so we tested the eggplant, the tomatoes, the lettuce and the cucumbers. Well, we need to do the peppers too, because the peppers are way over here.”

I sent the bags to Gabriel Fillipelli at Indiana University-Purdue University – and waited impatiently. Ripe tomatoes and cucumbers were piling up.

Finally, he got back to us.

“What I found with the samples you took from your soil was relatively high lead values. I was a little bit surprised. Some of them were actually above the EPA levels for playground soils, which is 400 parts per million.”

Great. I figure there’s no chance we could eat these vegetables. But Fillipelli says that’s not the case.

“The other vegetables, like the cucumbers, the eggplants, and peppers – they have very resistant outer skin so as long as you wash them well, very little lead can absorb inside those. The biggest risk you find with vegetables is not lead being sucked up by the roots and poisoning you, it’s actually the soil particles that cling on to the some of these vegetables, meaning beets or carrots or potatoes or, strangely enough, lettuce.”

In terms of children, Fillipelli says the real problem is letting them play in the bare dirt. He actually says covering it with grass or mulch would be safer.

But that doesn’t mean you can’t grow vegetables in a city. You can use containers, or build raised beds with clean soil, and use mulch in between.

It’s still a cheap source of healthy food, and a great way to teach kids about nature, biology and, unfortunately, pollution.

Keeping the Breadbasket From Drying Up

  • Bob Price is one of many farmers in Southwestern Kansas who signed up for a government program that pays farmers for their water rights and put portions of their land back into grass. (Photo by Devin Browne)

Right now, America’s Bread Basket
relies on an aquifer that’s nearly
drained. And, many say, it will dry
up if farmers keep pumping water
from it at the current rate. Devin
Browne reports the government plans
to pay farmers as one way to get them
to cut water use:

Right now, America’s Bread Basket
relies on an aquifer that’s nearly
drained. And, many say, it will dry
up if farmers keep pumping water
from it at the current rate. Devin
Browne reports the government plans
to pay farmers as one way to get them
to cut water use:

Bob Price is every bit the Heartland farmer. He’s dressed head-to-toe in denim with a belt
buckle the size of a small plate. Just like his neighbors, he grows thirsty plants like corn
and alfalfa. But, the land is so dry and so sandy that many agricultural experts think it’s
not suitable for farming.

When Price moved to Southwestern Kansas in 1973, it didn’t seem to matter that the land
was so dry. In his pick-up, on the way to his farm, he tells me that it was the beginning
of an irrigation boom.

“Out here everyone was getting up early, going to work, and all along Highway 50 it was
irrigation pumps, irrigation pipe, engines; this was like a frontier back then.”

At that time, the government heavily subsidized the costs of irrigation. The farmers were
getting an almost immediate return. Their land appreciated almost overnight once
irrigation was established.

Farmers began to pump water – and lots of it – from one of the world’s largest
underground water supplies, the Ogallala Aquifer. They pumped two-feet of water for
every acre they farmed, right onto their crops.

“Meanwhile, the water table is declining and the water that we’re pumping is coming
from farther and farther down and, even with the same energy cost, it cost more to suck
water out of the ground from 500 feet.”

Last year, it cost Price more than $200,000 for the electricity to run the pumps to irrigate
about 900 acres of land. It’s one of the reasons he started to consider other options.

At the same time, the government, on both the state and federal level, started to think of
how to save the water left in the Ogallala Aquifer. Rivers were drying up and several
states in the Plains were suing or being sued for taking more water than they’re allowed.

Several states initiated water conservation programs as a response; Kansas was the first to
do it without the threat of a lawsuit. The program started in 2007. The strategy: pay
farmers to permanently retire their water rights.

Price had actually been wanting to take some of his land out of crops anyways. He’s a
prairie chicken enthusiast and he wants to start a guided hunting business. Prairie
chickens need prairie grass.

“So we’re farming one day, and we’re thinking, ‘sure would be nice to get that into
grass,’ but that’s an overwhelmingly expensive proposition.”

It’s not expensive to plant or grow prairie grass. You don’t need any irrigation for either.
But you do need irrigation for a cover crop that the farmers are required to grow for two
years before they can get to the grass. Susan Stover is with the Kansas Water Office.

“If we did not get something re-established there, we could have potentially dust storms
again and sand dunes moving and really big blow-outs.”

Blow-outs like Depression-Era, Dust Bowl blow-outs. So Price has to plant a cover crop
and pat double what he gets from the conservation program just to irrigate it.

Ironically, the government pays him sizeable subsidies to keep other land in corn, which
needs water from the aquifer to grow. So basically, one government program is paying
Price to stop using so much water, while, at the same time, other government programs
are paying him subsidies to grow the crops that need so much water.

Price would actually like more money to put the land back into grass, but if he wants to
lead hunting trips for prairie chickens and he wants prairie grass, there’s only one outfit
willing to pay him anything to plant that grass – the government.

Mice Morphing at Warp Speed

Evolution takes place over long stretches of time: millennia and epochs. But some new research shows that animals might be changing much
faster than nearly anyone thought. Gabriel Spitzer has more on those
changes, and how they seem to be linked to humans:

Tall Trees Park is a little patch of green in Glenview, Illinois – a
northern suburb of Chicago. About a hundred years ago, a lot of this area
looked a lot like this. It was mostly farms and pasture and forest. And now
of course it’s a lot of strip malls and subdivisions and stuff. And the
population has grown seventyfold. The climate has changed, too. It’s
gotten a little warmer, a little wetter.

And all this has made life a lot different for the northern white-footed
mice who live here. It’s actually not just made life different for the
mice, it’s changed the mice themselves.

That gets back to a guy named Oliver Pergams. He’s an ecologist, and in
the mid-90s, he was looking at deer mice who live on the Channel Islands
off the coast of California. And he was taking these mice and comparing
them to museum samples of the same kind of mice from the same place, but
decades earlier.

“And I found something kind of strange – that the older specimens were
larger than the newer specimens, so they shrunk in size over a period of
about 30 or 40 years.”

That got him wondering if those relatively quick changes are happening in
other places. So years later, now on the faculty at the University of
Illinois at Chicago, he gathered up some of those White Footed Mice from
the Chicago suburbs. And he went to the Field Museum of Natural History…

(sound of a cabinet opening)
… where they have a hundred years of dead mouse specimens stored in
white metal cabinets.

“Here we have trays and trays of the northern white-footed mouse.”

With a tiny caliper, he’d measure their skulls, their feet, the distance
from their eyes to their noses.

“So this one here was collected by Aikley in 1903.”

And he compared mice from before and after 1950.

“Here are some skulls, this one was collected in 1989.”

Lo and behold, these mice had grown: by more than 10% on some measures.

This phenomenon goes way beyond Chicago. Pergams measured more than 1,300
rodents from four different continents – Alaskan lemmings, Mexican
gophers, Filipino rats. Some of them got bigger, some smaller. But across
the world, most of the animals have changed over time spans thought to be
mere evolutionary eyeblinks.

The next step is to figure out why.

“You can’t get in a time machine and go back and look to see what
actually happened. So the next best thing is to see if there’s
associations or correlations with big factors.”

He found the variations correlate with changes in climate and human
population density. The exact reasons aren’t clear – more people might
mean more yummy trash for the mice to eat, for example. That’s going to
take more research to figure out, and these critters might be overdue for
some extra attention.

“One of the questions is, well, why didn’t anybody notice this before?
And I think the answer is, they haven’t looked.”

Larry Heaney curates the Field Museum’s mammal collection. He says
Pergams’s research opens up new questions about how animals respond to
changes driven by humans.

“The implication is, these animals are changing very, very rapidly. So in
a sense, it’s good: they can change. But the other side of the coin is,
they’re having to change.”

Now, the question is, is this happening in other species, too? What about
birds or bugs or plants?

“There’s been this default attitude that if you go to one place and you
capture or you observe animals or plants, that essentially there’s going
to be the same animals or plants 50 years or 100 years later. I don’t
think that’s possible to assume at all. We have to include the fact of
this change in all of our decisions, from ecology to evolutionary biology
to conservation.”

Pergams’s findings show that even the most common creatures have more to
teach us – when we ask the right kinds of questions.

Tomato Blight Spreading

If you’ve been waiting all season
for that quintessential taste of
summer – a juicy, ripe tomato from
the garden – you might be disappointed.
This year a tomato blight has swept
across the Northeast and is moving
into Midwestern gardens and farms.
Julie Grant reports:

Walk around this outdoor farm market in Cleveland and just say the words ‘tomato blight’ – nearly anyone in earshot has a story to tell.

Susan Myers says her home garden has given over to what she thinks is late blight.

“But it’s pretty serious. I mean, it’s like wiping out everything. I have lots of tomatoes and all the leaves are dropping. I’ve never, ever had that before.”

It doesn’t look like the farmers here are having trouble with tomato blight. Most tables are piled high with bright reds and yellows.

Skip Conant has a beautiful display of heirloom tomatoes – but he’s not sure how many more weeks he’ll have fruit to offer.

Conant: “We definitely have tomato blight. It’s been a cool, wet spring, so, yeah. There’s a fair amount tomato blight.”

Grant: “What does it look like?”

Conant: “You’ll see a yellowing and curling on the leaves and then the stem will turn brown. The plant will become a very brown. Die from basically the inside out or the bottom up.”

It’s hard to tell yet if these Midwestern growers are starting to see the same blight that decimated the northeast tomatoes.

Bill Fry is a plant pathologist at Cornell University. He’s studied late blight for 35 years. Fry says it looks like irregular shaped black spots, and can appear on the leaves or the fruit. It can destroy an entire crop in just a few days.

This is the same blight responsible for the Irish potato famine in the mid-19 century. Growers have seen late blight since then. But Fry says, not at these epidemic proportions.

“The fact that it’s just everywhere is, I think, is the major difference from previous years.”

This wasn’t the first cool, wet spring on record. So, why has the blight so bad this year?

It’s kind of ironic. Fry and his colleagues have been studying the problem and think it’s probably because so many people are gardening. Millions more than just last year. And lots of those people bought tomato plants at stores like Home Depot, Kmart, Lowe’s and Wal-Mart.

“Infected plants were sold throughout the northeast in the box stores. They were transplanted to home gardens and from there the pathogen disbursed to other home gardens, to conventional and organic farms.”

Fry says you might not even notice at the supermarket. Commercial tomato growers spray lots of fungicide to keep away the blight. But organic tomatoes are getting harder to find.

But chefs and tomato lovers who’ve waited all season for those locally-grown heirloom – and especially organic – tomatoes aren’t finding what they want in markets in the northeast.

Back at the Cleveland market, chef and restaurant owner Karen Small has been waiting for tomato season – and it finally hit. She depends on this market for her produce and stops at just about every stand.

But as Small hears farmer after farmer describe what they think is late blight – she’s worried about the weeks to come.

“We’re accustomed to having tomatoes well into September, and maybe that’s not going to happen this year.”

Small plans to go home and rip out the tomato plants in her home garden – after hearing late blight described so many times, she’s pretty sure her tomatoes are infected.

There’s already a lot of genetically
modified corn and soybeans out there.
Now, Mark Brush reports, one company
is working on genetically modifying
trees:

The company is called ArborGen. And it’s working on altering Eucalyptus trees, so they can be turned into paper and biofuels more easily.

Eucalyptus is native to Australia and New Zealand.

But ArborGen has already got 330 acres of these genetically altered trees planted scattered across the South.

And now it wants the government to allow these trees to flower. And that has people like George Kimbrall worried.

He’s an attorney with the International Center for Technology Assessment. He says if they spread they’ll be bad for the environment.

“They’re water suckers. They don’t allow for much undergrowth. They’re poisonous to most animals. The leaves, the animals can’t eat them. Why would we want the south covered in Eucalyptus trees?”

When eucalyptus was brought over to California – it did become invasive. And there are some reports that it’s invasive in Florida too.

ArborGen says it’s altering these trees so they won’t spread in the wild.
