Many of the plans to build new coal-burning power plants have gone up in smoke. In early 2007, the Department of Energy noted there were 151 coal-fired electric generators on the drawing board. Lester Graham reports since then… nearly a hundred of them have been canceled—or shelved.

Many of the plans to build new coal-burning power plants have gone up in smoke. In early 2007, the Department of Energy noted there were 151 coal-fired electric generators on the drawing board. Lester Graham reports since then… nearly a hundred of them have been canceled—or shelved.

There are several reasons. The recession has tightened credit for building coal-fired power plants. Electricity demand has flattened- partly due to the economy—partly to better efficiency in businesses and homes. Lawsuits blocked some of the coal-burning plants. And some states are requiring power companies to compare the costs of burning fossil fuels to using alternatives such as wind because of concerns about climate change.

Ted Nace is with the environmental advocacy group CoalSwarm. He says he thinks this slow down in building coal-burning power plants is permanent…

“It’s a pretty profound shift in the American economy. And a lot of it’s being driven by economics, but also a lot of it’s still being driven by climate concerns.”

Some new coal-burning power plants did go online last year… but in real terms there was just as much new wind power installed.

World Governments Failing on Biodiversity

Transcript

A new report finds an agreement among the world’s governments to protect nature is failing. Lester Graham reports on the assessment which finds more animals, forests and other habitats are being lost.

World governments signed the 2002 Convention of Biological Diversity, agreeing to protect more habitat and species that are at risk. An assessment of the progress has been published in the journal Science and it finds biodiversity is at greater risk than it was when the agreement was signed eight years ago. Matt Foster is with the environmental group Conservation International. He says despite some government efforts to protect habitat, there have been more pressures destroying habitat and biodiversity.

“And it’s a scary prospect, not just from a biodiversity side, but considering that there are so many vulnerable people around the world for whom the services provided by nature and biodiversity are essential such as for water, for food and all of us depend on nature and forests especially to try to mitigate climate change.”

Foster says much more needs to be done by governments and the private sector to preserve natural areas and protect species.

Personal Care Products and ADHD

There’s been a rise in reports of behavioral disorders in kids over the past decade or so. Some researchers say genetics, lack of sleep, and chaotic households all contribute to things like ADHD. Now researchers say another cause could be personal care products. Julie Grant reports:

Transcript

There’s been a rise in reports of behavioral disorders in kids over the past decade or so. Some researchers say genetics, lack of sleep, and chaotic households all contribute to things like ADHD. Now researchers say another cause could be personal care products. Julie Grant reports.

Researcher Stephanie Engel at Mount Sinai College of Medicine says we’re all exposed to a group of chemicals called phthalates all the time. Heavier ones are used in plastics. Lower weight phthalates are used in fragrances, shampoos, cosmetics and nail polishes, to make them work better and last longer.

Some studies have looked at the relationships between phthalates and problems in reproduction. But Engel says phthalates are can be toxic to the nervous system. So she and her colleagues wanted to see if exposure to phthalates in the womb affected children’s brain development.

“WE ENROLLED A GROUP OF WOMEN WHO WERE PREGNANT AND RECEIVING PRENATAL CARE AT MT. SINAI. AND WHEN THEY WERE PREGNANT, WE COLLECTED A URINE SAMPLE FROM THEM. AND WE CONTINUED TO FOLLOW THE WOMEN AND THEIR CHILDREN FOR THE NEXT TEN YEARS.”

Engel says researchers tested the urine of the pregnant women in the study.

That’s because when we rub on lotion or use shampoo, phthalates are absorbed into our bodies, processed and eliminated.

She says the women who had higher levels of the pthalates during pregnancy reported more behavioral problems as their children got older:

“THEIR PARENTS, THEIR MOTHERS, REPORTED THEIR BEHAVIOR AS MORE DISRUPTIVE AND MORE PROBLEMATIC. SO THEY TENDED TO BE MORE AGGRESSIVE, HAVE MORE ATTENTION PROBLEMS, HAVE MORE CONDUCT PROBLEMS AND ALSO EXHIBIT MORE SYMPTOMS OF DEPRESSION.”

Engel says the problems looked like the types of problems found in children with ADHD: attention deficit hyperactivity disorder.

She says no behavior effects were found for the phthalates used in vinyl toys and other soft plastics. But the higher the mother’s exposure to phthalates found in personal care products, the more the symptoms were manifested by their children. The study was published in the peer-reviewed journal – Environmental Health Perspectives.

“I CANNOT SEE HOW THE CONCLUSIONS THAT ARE REACHED ARE SUPPORTED BY THE WAY THE STUDY IS DONE.”

John Bailey is chief scientist for the Personal Care Products Council. That’s the trade association for the companies that make things like cosmetics, shampoo and nail polish.

He says in any study that correlates a behavior to an outcome – there needs to be a control for outside influences.

“IN THIS CASE THOSE CONTROLS, AND AGAIN THESE ARE EXTREMELY IMPORTANT, NO MATTER WHAT TYPE OF STUDY YOU’RE DOING, ARE NOT THERE. THEY’RE NOT CONTROLLING FOR THE GENETICS OF THE CHILDREN, THEIR HOME ENVIRONMENT, THEIR DIETS.”

Without those kinds of controls, Bailey says there’s no way to draw a conclusion from the study.

Other scientists who’ve looked at phthalates say the Mount Sinai study shows a new area of concern about these chemicals. But it needs to be replicated by other research.

Still, this isn’t the first time this type of correlation has been made. In a study published last year, Korean researchers linked childhood exposure to phthalates to ADHD.

Researcher Stephanie Engel says environmental toxicants, like phthalates, clearly play a role in child neurodevelopment.

“THERE’S NOTHING ELSE THAT COULD EXPLAIN THE RESULTS THAT WE’VE OBSERVED. WE SPENT OVER A YEAR PROCESSING THIS DATA AND LOOKING AT IT IN MANY DIFFERENT WAYS. IT IS WHAT IT IS. THESE ARE THE RELATIONSHIPS.”

Engel says more study needs to be done. In the meantime, she says pregnant women might want to avoid phthalates in personal care products. They’re not listed on the label – but she says anything that has “fragrance” on the ingredients list probably contains phthalates.

Heritage Hogs

  • Barbara Schaefer thinks locally raised heritage meat makes economic and environmental sense. (Photo by Lucy Martin)

Variety isn’t just the spice of life. You could say it is life. And you can’t have variety without lots and lots of genes.

Farmers have spent thousands of years developing livestock that do well in different conditions.

Modern agriculture usually concentrates on just a few breeds that maximize profit. But a lot of people don’t want to see all the valuable genes in older breeds just disappear.

Variety isn’t just the spice of life. You could say it is life. And you can’t have variety without lots and lots of genes.

Farmers have spent thousands of years developing livestock that do well in different conditions.

Modern agriculture usually concentrates on just a few breeds that maximize profit. But a lot of people don’t want to see all the valuable genes in older breeds just disappear.

Lucy Martin visited a farmer who says the future needs to include heirlooms from the past.

(Schaefer entering barn: “Watch your head, it’s a little mucky in here…”)

It’s a bright winter day, inside a classic red barn in Southern Ontario. We’re admiring docile animals whose name says it all: Large Black Pig. They look fine. Even though this pig is listed as critically endangered.

Schaefer: Sometimes you’ll be standing here and you think there are no piglets and suddenly one rises out of the straw!

(Sound of contented grunting)

Barbara Schaefer used live in Toronto. Until a few years ago, her career revolved around managing environmental projects. But when she got laid off, she decided to put theory into practice.

Schaefer: I can’t save the polar bear, but I can save this breed. How many things can you say that about? And that’s why what I’m doing now is 200 times more relevant.

What she’s doing now, is weaving different environmental threads together. Preserving the genetic diversity of rare livestock. Putting marginal land to higher use. Trying to revitalize rural economies. Offering an alternative to factory farming.

Nearly all commercial pork across North America comes from just a few main breeds, usually reared in confinement systems. A lot of science goes into maximizing production. But Schaefer doesn’t think that’s the whole picture.

Schaefer: They’re packed in fairly close, they don’t get the benefit of being outside in the sunlight. They have a artificial concrete floor, which for them, is a horror. Because these guys think with their nose, they want to be turning things up all the time and there’s no opportunity for that.

(Sounds of distant tractor and more pigs grunting)

In the barn yard, I mingle with small herds of thigh-high, curious pigs as they as they mill about, soaking up sun. Some amble over to near-by pastures for naps inside cosy hay huts.

Schaefer’s customers include local restaurants and ‘foodies’, people who like to cook and eat.

Fans admire heritage breeds because these animals were bred to thrive in the specific conditions of small-scale, local agriculture.

Lawrence: They’re rustic, they’re hardy, they’re often good mothers.

Ted Lawrence has spent years on this cause with Rare Breeds Canada. Some really admire the animals. And then there’s the whole ‘insurance’ argument: odd breeds have genes worth keeping. As base stock for even newer breeds, to adapt to changes in climate, or to survive some epidemic.

Lawrence: Food security, that will turn heads more quickly than saying we have to preserve the genetic diversity of minor breeds.

If these animals are special, why slaughter them?

Lawrence: That is actually a slogan that has been used in Great Britain: ‘We must eat them to save them’. It sounds counter-intuitive but what’s the purpose of breeding them if you can’t make any money, if you can’t sell them? Then the genetics will not continue. The breed will go extinct.

(kitchen clatter and music playing at Murray Street Restaurant)

Chef Steve Mitton co-owns a restaurant in Ottawa which features Schaefer’s pork. He’d hate to see old breeds die out.

Mitton: I mean, I get entire animals in and break them down from head to toe, and we use every last bit of it. The yield of the Large Black, in particular, is outstanding.

Mitton says more and more people care about where their food comes from and how animals are treated.

Mitton: I just want to broaden their horizons, open people’s minds a little bit, so they know that this is out there. And it’s just as good as commercial pork.

Most meat eaters have no idea what breed of animal ends up on their plate. But making sure there are lots of breeds around can help keep those plates full, and tasty.

The Environmental Protection Agency
has released its first comprehensive
survey of the nation’s lakes. Samara Freemark tells us what
the study turned up:

More than half the nation’s lakes are in good condition. That’s according to a nationwide survey just released by the EPA. But the agency found that 44% of lakes ranked only fair or poor.

The survey identified two major problems facing lakes. First, many of them are surrounded by development. And that can mean dirt and polluted water running off into the lakes.

And second, many lakes contained high levels of nitrogen and phosphorus, which can lead to harmful algae blooms.

Susan Holdsworth is with the EPA. She says those findings were concerning.

“These stressors are both widespread and pose a significant threat to the condition of our nation’s lakes.”

Holdsworth says the EPA will use the data to assess how well government programs are doing at protecting lakes. The results will also help set future EPA priorities.

Trying to Speed Up Green Tech

It takes time for green technology
to develop. The US Patent office
has one idea to speed things up,
but Shawn Allee reports
that probably won’t solve the problem:

The US Patent Office is working through 25,000 green tech patents for things like better solar panels.

The office wants to give preferential treatment to 3,000 green tech patent applications. That could save a year of waiting time for approval.

But not everyone thinks a Patent Office backlog is the problem.

Stuart Soffer is a patent analyst in Silicon Valley. He says green tech just takes time and money.

“It really takes an investment, infrastructure and R and D. We can make a little wind mill that will generate power in your back yard, but scaling that to power cities is a different problem.”

Soffer says sometimes, patent delays are companies’ fault, not the government’s. So, speeding things up at the Patent Office might not get green tech in the marketplace any faster.

Cellulosic ethanol is supposed to
be a green fuel for cars – greener
than conventional ethanol made from
corn. The government wanted industry
to create loads of cellulosic ethanol
next year. Shawn Allee reports
industry might provide just a trickle:

The fuel industry’s supposed to create 100 million gallons of cellulosic-ethanol next
year. But industry leaders say they might create just 12 million gallons.

Wes Bolsen is with Coskata. His company can create ethanol from wood chips and even
household trash. Bolsen says companies like his found some investment money – but the
financial crisis created delays.

“We’re building refineries – 300, 400 million dollar assets and that’s a lot of money
to come together. We’re two years delayed, the whole industry. We can’t open them
in 2010. Facilities will start opening in 2012.”

The federal government might have to shift mandates for cellulosic ethanol into the
future.

That could mean the country uses less efficient ethanol from corn, or keeps using more
gasoline.

Funding for Hydrogen Vehicles Hit Hard

Transcript

The Department of Energy wants to cut funding for the development of hydrogen powered vehicles. Mark Brush reports the Energy Secretary has decided that cars powered by hydrogen are too far off:

Six years ago, President George W. Bush proposed spending 1.2 billion dollars to develop hydrogen power cars.

Now, Stephen Chu, President Obama’s Energy Secretary, says hydrogen powered cars aren’t yet practical for today’s market.

Chu says they’d rather spend money on things like plug-in cars and cars powered by biofuels. Things that can hit the road now instead of 20 years from now.

People working on hydrogen powered vehicles aren’t too happy about the cuts.

Patrick Serfass is with the National Hydrogen Association.

“I’d say the hydrogen industry is perplexed. The administration has a lot of smart people in it and they have done a lot of great things for many parts of the renewable energy sector. But the proposal to eliminate the hydrogen vehicle program is a mistake.”

Serfass says hydrogen powered cars are not as far off as the Energy Secretary might think. He and his group are trying to persuade members of Congress to put research money back into the budget.

Growing a City in a Greener Way

  • Trussville, Alabama Mayor Gene Melton may not be a staunch environmentalist - take a look at his car - but he still thinks greenspace is important in his city (Photo by Gigi Douban)

For many small town mayors, growth is all good. After all, more houses means more tax revenue, more retail, more jobs. One Alabama mayor agrees, but he also recognizes green space is an amenity worth keeping. And for that, the timing couldn’t be better. Gigi Douban reports:

For many small town mayors, growth is all good. After all, more houses means more tax revenue, more retail, more jobs. One Alabama mayor agrees, but he also recognizes green space is an amenity worth keeping. And for that, the timing couldn’t be better. Gigi Douban reports:

Here at the grand opening of a subdivision in Trussville, Alabama, a few dozen families gather outside the sales office for the usual ribbon cutting with giant scissors.

(sound of applause and cheers)

Soon, everyone heads down to the Cahaba River. The river literally will be in the backyard of these houses once they’re built. On the river, they’re having a rubber duck race.

(announcement of duck race)

It’s gimmicky, but these days developers will do just about anything to attract potential buyers.

Another developer had approached Trussville about building homes along the Cahaba River, but then the housing market took a nose dive. The developer wanted out.

Trussville Mayor Gene Melton says the city would have been crazy not to buy the land.

“This property was probably going to sell for $35,000 or $40,000 an acre. We got to the point where we were able to acquire this for $4,500 an acre.”

The city could have turned it into an industrial park or zoned it for retail. But instead, they’ll turn it into a greenway. It’ll connect to nearby parks with the river as the centerpiece.

Now, the mayor of Trussville is not a staunch environmentalist, by any measure. He tools around the city in a gas guzzling SUV. He’s pro-development. But, he says, the same way a city needs development, it needs greenspace, too.

“Have you ever flown in to a big city like Atlanta or Los Angeles and for miles and miles all you see is rooftops? Well that’s how not to build a city.”

The Cahaba River watershed stretches through Alabama’s most populous county. Recently, heavy development along the Cahaba has polluted the water. It’s endangered habitats not just here, but downstream. Trussville is very near the headwaters, so what happens there affects the entire river.

Randall Haddock is thrilled about the new greenspace. He’ a field director with the Cahaba River Society, a conservation group. Haddock says the Cahaba River is among the most biologically diverse in the country.

“It turns out that Alabama has more fish species, more snails, more crayfish, more turtles, freshwater snails more than any other state in the US. So when it comes to things that live in rivers, we’re at the top of the list by a long way.”

(sound of people walking near river)

Haddock says all along the Cahaba, he’s seen plenty of examples of how not to build near the river.

He says this greenspace is an example of how easy it is to minimize impact. Keeping grass on the ground not only means a cleaner river, but it might help reduce flooding.

“When you make so many hard surfaces, the water runs off real fast and gets into the river real quick. And you’ve increased the volume of water and the only response that a river can make is to get bigger.”

The bank erodes, the water is polluted and soon, you start to see species diminish.

(sound of high school students)

David Dobbs is the city’s high school environmental science teacher. He takes his students out behind the school to check on the river. The result: a clean bill of health.

“All the little bugs, they end up being food for the fish, and the more they are of the good ones that are here, that means there’s more food for the fish, so therefore there’s more fish, it’s a very healthy part of the river.”

Trussville, like many small towns, still says without growth, there’d be no city. But now they know, that growth has to protect one of its top amenities – the river.

The Fish Are Floundering

A new study shows things are getting
worse for fish in North America. Lester
Graham reports water pollution is the problem:

The U.S. Geological Survey finds nearly twice as many kinds of fish are now listed
as imperiled today than just 20 years ago. 61 types of fish have gone extinct.

Howard Jelks is the lead author of the study.

He says the decline in fish is because most streams, rivers, and lakes are in worse
shape because of sprawling development, farmers’ chemicals, and pollution washed
off parking lots and streets.

Even if you don’t go fishing, or really even care about the fish, Jelks says there’s a
reason you should care.

“You know, at a certain point, it’s a quality of life issue. If it’s not good enough for
some of these fish, it’s probably not good enough for your kids to swim in.”

And the experts say that means we all have to think about what’s going down the
drain and what chemicals we’re putting on lawns, and on farms.
