Biodegradable silverware has
popped-up in local coffee shops, fast
food joints, and even the Olympics.
But how eco-friendly are biodegradable
utensils? Kyle Norris has this report:

Companies are making disposable utensils from things like corn,
potatoes, and sugarcane. And many brands label their silverware as
biodegradable.

Sarah Burkhalter is a news producer with the environmental
journalism website, Grist.org. She says making silverware from
materials other than plastic is a step in the right direction.

“But I think that the encouragement should not be for people to feel
like they can use a fork for three minutes then toss it in the compost
and be done with it. I think the emphasis needs to be on reusing your
silverware. Whether that be metal or plastic or corn.”

Burkhalter says the other tricky part is that you need to read the
manufacturer’s instructions. She says many of these utensils are only
biodegradable in special composting facilities.

Which means the utensils will not biodegrade if you toss them into a
backyard composting bin.

Because of feed and energy prices,
some cattle farmers are scaling back.
They’re not reducing the size of their

Today’s cattle are much bigger than they were back in the 1920s. They’ve been bred to
big and beefy. But, it turns out, you can actually produce more meat with the smaller
cattle.

Richard Gradwohl has been breeding miniature cattle for more than forty years. He
says with today’s larger beef cattle on five acres, you can produce 2400 pounds of
meat. He can raise as much as 7000 pounds of beef on that same five acres.

“It’s surprising to me how many large cattle breeders call me almost every day
because they’re interested in reducing the size of their animals to achieve more
feed efficiency.”

Gradwohl thinks the emphasis on breeding large cattle might be reversing.

We hear a lot about the coming

promise because it’s a clean burning gas.
But, for the most part, you have to burn
dirtier fossil fuels to make hydrogen.
Scientists can produce hydrogen from water.
But the process is expensive. Julie Grant
reports on new science that has researchers
buzzing:

MIT researcher Daniel Nocera has found a cheaper way to get hydrogen
from water molecules. Researchers already have been able to do this – but
only with a precious metal – platinum. It costs nearly $2000 an ounce.

Nocera’s team discovered a material based on cobalt that does the same job.
Cobalt costs more like $2 an ounce.

James McCusker is an expert on solar energy conversion at Michigan State
University. He says the discovery has researchers excited.

“A, it works. But B, it works in such a way that it’s very, very easy to put
together. And it’s made of very inexpensive materials. They’re really
potential game changers in this field.”

McCusker says there’s still a lot of work left before we’re ready for a
hydrogen economy.

The new research was published in the journal Science.

Winter’s Chill to Bring Bigger Bill

As summer winds down, you’re

As summer winds down, you’re
probably not thinking about your
heating bill. But that’s something
market analysts are thinking about
right now. And reporter Kyle Norris
finds the predictions of what it will
cost to heat your home are going up
in a big way:


This year the average cost of heating your home is going to cost a good
chunk more than what it did last year.

Doug MacIntyre is an analyst with the US Energy Information
Administration.

“We’re estimating that, on average, the household using natural gas to
heat their home will be spending 24% more than last year. For heating
oil we think the increase will be even higher with house holds spending
about 36% more than they did last year.”

Those predications are made by looking at the cost of things like natural
gas and crude oil. And by analyzing the weather forecast for the up-
coming winter.

MacIntyre says he does not expect these expensive heating costs to go
away anytime in the next few years.

Hi-Ho, Hi-Ho, on a Singing Hike We Go

In many cultures, people sing as
they work or as they travel. But in North
America, most of us aren’t comfortable
singing out loud in public. Karen Kelly
reports on a music teacher who’s trying
to change that – by taking her students
into the woods:


“Ooh, ah. Ooh ah. Here’s another part: aay-oh”

Maura Volante is leading a troupe of six students through a path in the forest.

It’s rainy, buggy and muddy. But everyone quickly gets into a groove – both with their
feet and with their voice.

(sound of walking song)

“There’s lots to look at all the time: the green and the shadows, the lake, the sky and all
the different vegetation. And when I’m feeling relaxed and I’m in my body and I’m
walking along and I’m in nature like that, it just makes me want to sing. It inspires me to
let my voice out.”

Volante teaches singing in Ottawa, Canada. For her, people don’t need a good voice to be
able to sing. Instead, she says singing just comes naturally to humans, like breathing and
walking. Which is why she tries to get people outside where they can experiment and
make mistakes.

“It’s kind of like recreational softball. It doesn’t matter if someone sucks at it. They can
still play. It’s for fun.”

(sound of more singing)

We spend about two hours hiking around the heavily-wooded Mud Lake.

I did some research to see if I could find any other organized singing hikes. I found one
at a bible camp in Virginia. And there’s one at a kibbutz in Israel. And, at Yellowstone
National Park? They recommend singing loudly – or shouting – to scare the bears away.

Of course, lots of people like to sing when they hike. On this walk, Kathy Woodgold
says she sings differently when she’s walking in nature.

“When we’re in the woods, it brings sort of a primitive spirit. Like, I’m thinking, let’s
pretend we’re not civilized, instincts, and so on. And maybe that opens up a creative
spirit. It frees us to sing random notes, instead of having to feel like we have to do a
predefined melody.”

This isn’t really a conservationist group. But teacher Maura Volante says, in some small
way, doing this helps the planet.

“I think there is a benefit to the environment for people to sing more because that gets
them to appreciate nature more and appreciating nature helps you be committed to
preserving it.”

(sound of singing “O Canada”)

The small group stops at a dock overlooking Mud Lake for their only performance of the
day. The audience? Ducks, frogs and mosquitoes.

But they give it their all.

High School Student Is Biofuel Whiz-Kid

It’s hard to be optimistic about
paying $4 a gallon at the pump.
But when you’re a teenager working on new
ways to make cheap fuel, it can be pretty
exciting. Julie Grant met one high school
student who is showing off his biodiesel
converter at the county fair:

(sounds of the fair)

The Fairgrounds sit in a quiet countryside of rolling green
hills. Small children yell and wave to family members as
they enter the Fair. There’s a steer auction in the barn. And
an antique tractor pull in the grandstand.
It’s like a scene is right out of a Norman Rockwell painting.

I’m here to talk with John Russell. He’s walking around in
faded wrangler jeans. A red t-shirt with the sleeves cut off.
And a ballcap advertising a tractor company.


“We’re at the Columbiana County Fair in Lisbon, Ohio. In
the junior fair building.”

John is 17 years old, and amidst 4-H project displays, he has
set up his view of the future. His homemade biodiesel
converter.

It’s a rectangular box – nearly as tall as me.
It’s made of stainless steel. There’s a row of toggle switches
along the side. They light up when John plugs it in. He’s
been working on this for more than a year, and says it
makes vegetable oil into a usable fuel.

“I started out with new oil from Save-A-Lot. I went down to
the local grocery store and picked up a bottle of frying oil.
And just from a recipe I found online, with methanol from an
auto parts store, they sell it as heat. It’s gasoline antifreeze.
Just methanol from an auto parts store, Caustic soda from a
hardware store, and oil from a grocery store, I set out to
make this fuel. And it took me couple of times. I finally got it
right when I actually tried a batch of waste vegetable oil from
the valley drive in. So that was my first successful batch.”

Last year, John was only able to fill a Gatorade bottle with
his fuel. Soon, he expects to convert 240 gallons of
vegetable oil into biodiesel in a day.

He hasn’t quite figured out how much the electricity costs to
run the thing, so he doesn’t know how much it’s costing him
to make the fuel.

Back five years ago, he met a guy who claimed to be making
biodiesel for 46 cents per gallon.

Headlines then were already screaming about skyrocketing
fuel prices. 1.60 per gallon. That’s what sparked John’s
interest in making his own converter.

“46 cents a gallon was pretty cool. And I’m into sustainable
agriculture. It’s recycling and its ecofriendly. The
culmination of all those things, that’s what makes it
interesting for me.”

Now that’s he’s almost 18, most of John’s friends are into
cars. And they’re taking an interest in his biodiesel project.

John Russell: “I’m a senior in high school. So most of my
friends’ reactions are ‘when are you going to give me free
fuel?’ But they all think it’s pretty sweet. It does make fuel a
lot cheaper than you could buy it at the pump.”

Julie Grant: “How much are you selling it for?”

John: “Well, I can’t sell it. Or else I’ll get in trouble with the
big man.”

Julie: “Is your dad the big man?”

John: “no. The IRS.”

He’s got to do some research into state and federal laws.
John wants to use the fuel to run his family’s tractors and
help heat homes in his neighborhood.

He’s not sure if biodiesel is the future of fuel, or even in his
long term future. But John is sure he wants a career in
green industry.

“Anything that’s gonna be tied into this fuel situation that
we’re faced with. Something’s gonna change and
something’s gonna change fast. So I’m very excited for
what’s going to happen.”

For now, John’s trying to put the finishing touches on his
converter so it’s ready for the Ohio state fair later this
summer. He’s the new face of agriculture – making eco-friendly practices into traditional American values.

Woody the Woodpecker: Save My Home!

Red-headed woodpeckers used to
be just about everywhere east of the Rocky
Mountains. But these days the number of
red-headed woodpeckers is about half of
what it was fifty years ago. Stephanie
Hemphill reports volunteers
are working on a new project to get people
to help red-headed woodpeckers. They’re
encouraging landowners to let dead or dying
trees stand rather than cut them down:

You can’t miss Red-headed Woodpeckers. They have long beaks,
bright red heads and snowy white breasts. And if you go to the right
place, you can find a lot of them.

“Somebody told me that there was Red-headed Woodpeckers up
here, so I walked five minutes, and there was a Red-headed
Woodpecker, and it flew into a hole in a tree, and I says, ‘wow, this is
easy.’”

Lance Nelson first visited the Cedar Creek Ecosystem Science
Reserve about a year ago.

“And then I came up this year and found 8 nests. But the young
make a lot of chattering, so you can usually tell where the nest is.”

Today they’re not hammering on trees – the sound most of us
associate with woodpeckers – but they’re doing plenty of chattering.

This reserve in southern Minnesota looks a lot like how much of the
Midwest used to look.

There are clumps of big oak trees here, separated by open areas of
native grasses, shrubs and wildflowers. The biologists call it an oak
savannah.

And there are Red-headed Woodpeckers everywhere – about fifty of
them on this 500-acre patch of ground.

“There’s a red-headed, and he’s got a baby with him. God, they’re
beautiful. They are so beautiful.”

That’s Chet Meyers. After a career as a college professor, he’s now
in charge of an effort to make more places where Red-headed
Woodpeckers can build their nests and raise their young.

If they can figure out exactly what the woodpeckers like so much
about this place, maybe they can come close to reproducing the
same conditions other places.

Chet Meyers is marking every tree where the woodpeckers have
nested.

“See these two trees to the left, go to the right-most one, it forks, and
there’s a broken-off snag up there, looks like a ‘Y’. That’s where the
babies were sticking their head out a couple weeks ago. It was really
cute.”

Once the trees are marked, the group will catalog exact descriptions
of each tree. They’re hoping to come up with a profile of the perfect
home for Red-headed Woodpeckers.

“And we’re going to measure the diameter of the tree, how high the
nest cavity is, the species of the tree, is it alive or is it dead, so we
can get some data on what seems to be the preferred habitat.”

Once they’re pretty sure they know what the woodpeckers like, they’ll
reach out to land owners. They’ll to try to get them to leave dead and
dying trees standing.

That could work on old abandoned farms, where there are trees and
open spaces. Or in cemeteries. Or around golf courses.

“If our theory – see, this is all theory – if our theory is correct, the golf
course replicates an oak savannah and there should be birds there.
So, that’s what we’re hoping.”

And Meyers says helping woodpeckers means helping other wildlife
too.

“The woodpecker is called a primary nester, it digs the cavity. But
flying squirrels, mice, snakes, bluebirds, tree swallows – there are lots
of other animals that are secondary nesters. They can’t drill the hole.
But they live there. So what we’re trying to do is preserve the habitat
so the woodpeckers drill the hole and when they leave, something
else will come in and live in it.”

The researchers think if you have dead or dying tree, that could be a
home for a Red-headed Woodpecker. But usually homeowners are
worried the tree could fall and damage something, Meyers says you
can cut off the top and some of the bigger branches and leave the
rest of the tree standing. They think the red-headed woodpecker will
be just as happy.

Power Plant Pollution From Plug-Ins?

  • Some people get a little concerned about more electrics and electric-hybrid cars. That’s because 50% of electric power in the U.S. comes from coal-burning power plants. And, just about every state wants to build more power plants to meet peak demand. (Photo by Ed Edahl, courtesy of FEMA)

The big automakers are working on
coming up with plug in hybrids. By the
end of 2010, G-M and Toyota plan to have
cars you can plug in to charge up batteries,
backed up with small gas powered engines.
Lester Graham reports there are concerns
about whether pollution from power plants
will be any better than pollution from tailpipes:


I was out the other day with a guy who converted his Saturn four-door into an all electric
vehicle. Did it all himself.

His name’s Bob Gurk. He’s one of a lot of people who think there’s a better way, and
they want you to see for yourself.

Bob Gurk: “Here are the keys.”

Lester Graham: “I’m drivin’?”

Guys like Bob Gurk think the big automakers should have come up with electrics and
plug-in hybrids a long time ago.

Lester Graham: “Unplug here?”

Bob Gurk: “Yeah.”

(sounds of driving)

Bob Gurk says, sure, he spent a lot converting his car to electric. And there are some
sacrifices: no air conditioning, he can only go just a little over 50 miles without a charge,
but then, he’s not paying close to four-bucks a gallon for gasoline now.

Bob Gurk: “I figure it’s about three cents a mile.”

Lester Graham: “Three cents a mile?”

Bob Gurk: “Yeah.”

Lester Graham: “As opposed to gasoline, which is?”

Bob Gurk: “Ten cents a mile, I’d say. At least.”

Some people get a little concerned about more electrics and electric-hybrids. That’s
because 50% of electric power in the U.S. comes from coal-burning power plants. And,
just about every state wants to build more power plants to meet peak demand.

A guy who’s supposed to know something about electric cars is Andy Frank. He’s at
the University of California Davis. Some call him the father of the plug-in-hybrid. Andy
Frank says we don’t use all the power that’s available right now.

“What a lot of people don’t realize is that the grid actually has excess capacity. The
reason why is there has to be enough capacity to satisfy the peak draw in the middle of
the day. But, at night everybody turns off their lights and that draw goes down to about
anywhere between a half and two-thirds of what is required during the peak of the day.”

So, the idea is you could plug in your plug-in hybrid overnight.

“And then the question is how many cars could you charge with that idle capacity on our
existing grid? About 75 to 80% of cars in our entire fleet in the U.S. could be charged
with that excess capacity that we currently have.”

That’s assuming most people would only plug in at night, during the off-peak hours. If
most of them did, that would be a lot of cars that would not be emitting pollution from the
tailpipes.

But that also means some power plants will be burning more coal at night, billowing out
pollution, including greenhouse gasses.

Dustin Dwyer reports on automotive issues for Michigan Radio and he’s covered this
issue.

“One of the benefits, the power companies will tell you, is that if you have millions of
tailpipes out there spewing emissions, it’s much more difficult to capture those emissions
or manage those emissions than it is to manage coming out of one smokestack at the
power plant.”

But, you do end up shifting some pollution upstream to the power plants. And that
would pollute rural areas more, because that’s where they build the power plants.

The experts say that’s why we ought to start building parking lots with car ports covered
in solar panels, put up more wind turbines, and find other ways to use energy better – to
power all those electric and plug-in hybrids that are coming.

There’s been a lot of talk during the Beijing Olympics about China’s

efforts to be more environmentally friendly. The host of the 2012 Summer

games hopes to do even better. Julie Grant reports that London is billing its

Olympics the first low environmental impact games:


London already has great sporting venues, so it plans to use places like Wimbledon for the Olympics.

The city doesn’t want to build new facilities that will just sit there after the games are over. Taxpayers in Sydney, Australia, are still paying millions annually for underused facilities built for the 2000 Olympics.

London is building an Olympic Park, but has chosen an old industrial site in a neglected section of East London and hired local workers for the clean up.

90% of the demolition materials have been recycled or reused.

Also, the city doesn’t want the symbol of the games – the flame – to burn fossil fuels and add to the global warming problem. So Olympic officials are searching for a low carbon alternative.

Chicago Looks to Beijing for Green Olympics Lessons

The Olympics in Beijing are into its final week. The city has delivered blue skies and
taken other steps to make the games environmentally friendly. Meanwhile, the City of
Chicago is bidding to host a green Olympics in 2016. The bid committee members are at
the games to observe. Violet Law is in Beijing and has this report:

(sound of a bus pulling up and announcing the stop)

As more Chinese are getting richer they are driving more. But most still catch the bus to
the Olympic venues, because there’s no parking for spectators. Officials have added
special bus routes to take people to the games – for free.

(sound of a bus pulling away)

But this is not your typical diesel-burning bus. Beijing now boasts the world’s largest
fleet running on compressed natural gas. That means less pollution and CO2 emissions.

Doug Arnot is in Beijing. He oversees the planning of operations and sports venues for
Chicago’s bid for the 2016 Olympics. He says Chicago can do even better if it gets to
host the games.

“We believe that by 2016 all of our buses and all of our vehicles in the Olympic fleet will
be alternative energy or hybrid vehicles. That will have a huge impact on the
environmental imprint if you will of the Olympic Games.”

(sound of an English-language announcement of an Olympic venue stop on Beijing
subway and the noise of the train speeding through the tunnel)

Beijing has had to tackle a host of environmental problems. Most people know about the
city’s massive efforts to clean the air. But it also opened five new subway lines just in
time for the Olympics. Its added wind power generators.

But hosting the Olympics might have made one problem worse.

(sound of water fountain)

Beijing already has a water shortage. For the Olympics, workers planted trees and
flowers and added thirsty landscaping all over the city. New parkland and an urban forest
form the bulk of the Olympic Green.

‘Friends of Nature’ is the country’s oldest grassroots environmental group. Zhang Boju is
the head of research. He’s torn over seeing all this greenery.

“We think this grassland and man-made forest is a very, very important part of greener
Beijing, but it also has some problems. Is this fit for Beijing, a city which has limited
water resource?”

Hosting the Olympics has spurred the government to open up new facilities to recycle
water.

Achim Steiner heads the United Nations Environmental Programme. Steiner says he’s
pleased to see that China has seized the opportunity. His agency will issue a report
assessing the environmental impact of the Beijing games by the end of this year.

“What the Olympic Games provided was an opportunity to showcase and create a
platform to demonstrate what is possible if you’re determined to address these issues. A
great deal has been done and shown in the last seven years. What we are looking for here
is what kind of long lasting improvement the Games have brought.”

Beijing will take advantage of all these improvements. All of the newly built venues will
stay. Some, including the iconic Bird’s Nest and Water Cube, will be converted into
commercial use. The wind power generators will produce enough energy for 100,000
families.

There are also small things that show how hosting the Olympics has made Beijing a
greener city. Doug Arnot of the Chicago bid committee is taking notice.

“Every event you go to sometimes it’s not the big idea that you see, but the smaller idea
that you see. One of the things I’ve noticed is the staff and volunteers and the way they
have addressed green issues. They’re very conscious of where the recycling waste
baskets are. That may seem to be a small issue. But when you have tens of thousands of
people at your venues on a daily basis, it is very important.”

And Chicago is hoping both the small things and the big changes in its environmental
approach will win it a chance to host a green Olympics in 2016.
