An invasive plant called Garlic Mustard is taking over forests in the Eastern half of the country, and it could be causing long term damage. Julie Grant reports that some people are getting smart in their efforts to get rid of Garlic Mustard:

Brad Steman spends a lot of time in the woods. He likes the serenity. But as we walk through this park, he winces. The entire forest floor is carpeted with one plant and one plant only: Garlic Mustard. Thousands of them. The thin green stalks are as tall as our ankles.

Steman calls it “the evil weed.” Its triangle-shaped leaves shade out wildflowers, so they don’t grow. Even worse, Steman says Garlic Mustard poisons baby trees.

“So a forest filled with Garlic Mustard you will see very little regeneration of that forest, very few seedlings, small trees. So looking down the line, once those large trees start dying off there’s nothing to replace them. And that now is the greatest threat to our Eastern forests.”

Steman says every year Garlic Mustard is spreading farther into the woods. Anywhere the ground is disturbed.

“So here’s a big stand of it along a trail. This is typically where it starts. This is thick. This is a healthy stand. There’s potential there for an explosion. So we should probably pull some. I’ll pull some; you don’t have to pull any.”

Thank goodness he’s doing it – it looks like tedious work. Steman crouches down and starts pulling them out of the ground, roots and all. He sprayed herbicide on some of it, and so far this season he’s filled 35 big garbage bags with Garlic Mustard plants. He’s sick of weeding. But it doesn’t look like he’s made a dent here. All along the Eastern half of the US and Canada people are pulling up Garlic Mustard from parks and just throwing it away. But some people don’t like this approach.

“All these people are very shortsighted when they’re doing that.”

Peter Gail is a specialist in edible weeds.

“They’re not looking for other alternative uses – creative ways to use these plants that would be profitable, that would be productive.”

Gail says: “If you can’t beat ‘em, eat ‘em.” People brought Garlic Mustard to the US in the mid-1800s because they liked it, to eat. And they even used it for medicine. Yep. That same nasty weed.

Gail says today Garlic Mustard just needs an image makeover. Some weeds have become big stars in the cooking world. A few years ago Purselane was just an unwanted vine, with its fleshy, shiny leaves matted to the ground. Now it’s known as a nutritional powerhouse, and is the darling of New York and LA eateries. Gail wants that kind of fame for Garlic Mustard.

“This is a Garlic Mustard Ricotta dip, Garlic Mustard salsa, stuffed Garlic Mustard leaves – these are all things you can do with this stuff. It’s fantastic!”

Garlic Mustard seeds taste like mustard, the leaves taste like garlic and the roots are reminiscent of horseradish. Gail says people should go after Garlic Mustard in the parks, but then they should take it to farm markets to sell.

“My normal statement is that the best way to demoralize weeds is to eat them. Because when you eat them they know you like them and they don’t want to be there anymore, and so they leave.”

Today Gail decides to blend a pesto using the early spring leaves. He picks every last Garlic Mustard in his yard to make a batch.

“Well there it is, garlic mustard pesto. And it isn’t bad, is it?”

“It’s delicious.”

Environmental groups say extracting tar sands oil causes a lot of water pollution. Matt Price is with Environmental Defence Canada:

“We keep on presenting the evidence to the government, and they just sort of keep on ignoring it which is why we filed this citizens’ complaint.”

They’ve filed the complaint under the North American Free Trade Agreement. The say oil companies in Canada are not complying with Canadian environmental laws and that might be a violation of the NAFTA treaty. So, his group and others are taking the fight to Canada’s trading partners.

They’re hoping the U-S and Mexico will step in.

Several investors’ groups want four major oil companies to reveal the risks of getting oil from Canadian tar sands. Rebecca Williams reports shareholders will be considering this at BP’s general meeting this week:

Tar sands are kind of like they sound: they’re sand or clay soaked in oil. Canada’s tar sands are the second largest oil reserves in the world, so oil companies are all over them. But it’s a dirtier source of oil.

Several investors groups have filed shareholder resolutions with BP, Conoco-Phillips, Shell, and Exxon-Mobil. They want companies to reveal the risks to stockholders of getting oil from tar sands.

Emily Stone is with Green Century Capital Management.

“We want these companies to be more forthright about what they see as the big risks and how they’re mitigating those risks.”

She says risks include dealing with pollution… and lawsuits from native tribes that live near the oil sands.

BP did not want to be recorded for this story. But in a statement to shareholders, BP told them to vote no. BP says Canada’s oil sands are a proven and secure source of oil.

American gasoline refineries are
expanding to process a dirtier kind
of oil. Shawn Allee reports
one company’s plans hit a snag:

The BP fuel refinery in Northwest Indiana wants to process more Canadian tar sands oil.
Processing tar sands crude creates more air pollution than normal. The federal
government wants more air pollution figures from BP before signing off on an air
permit.

Groups like the Natural Resources Defense Council pressed the government to step in.
The NRDC’s Ann Alexander is glad BP’s tar sands project is getting scrutiny.

“If tar sands are going to be developed, we think it’s it’s critical they be developed in
a way that complies with the Clean Air Act, because the Clean Air Act is there to
make sure it’s not the community that pays for development of tar sands through
increased pollution and the health problems that result, but that it’s BP who pays
those costs.”

BP’s tar sands oil project in Indiana is just one of several going on in the Midwest.

Teen Pedals Across Canada for Climate Change

All over North America, people
are becoming more concerned
about the dangers posed by
climate change. Karen Kelly
spoke to a teenager who comes
from the far north of Canada,
one of the areas of the continent
that’s already feeling the effects:

Malkolm Boothroyd is 17. He lives in Whitehorse in the Yukon, a province at the northern tip of Canada.

It’s a wild mountainous place, with huge caribou herds, moose, bear, and foxes. It’s also a place where climate change is already evident.

The winters are shorter. The permafrost and sea ice are melting. And for young people like Boothroyd, it’s a source of worry.

“Climate change is impacting wildlife patterns, tundra ponds are vanishing. We are one of first places that will feel the severe impacts of climate change. Growing up in the Yukon, you’re maybe more aware of that.”

Boothroyd says already the native Inuit tribes are having a harder time living off the land. And he felt frustrated by what he sees as the Canadian government’s lack of action.

The government has not kept international commitments it made to reduce the gases that cause climate change. So he decided to head to the capital city of Ottawa to lodge his complaint.

Ottawa is 3,700 miles away from the Yukon.

(sound of gears)

Boothroyd hopped on his bicycle.

“I think there are days when you question your sanity, when you’re sitting out in the rain with black flies all around your head and with a soaking wet tent and wondering, ‘why am I doing this?’ But I don’t think there was any time I wanted to go back or anything like that. I just wanted to see the project through and make sure we were here on Parliament Hill to give our message to the government.”

It took him just under three months to ride from the northwestern tip of Canada near Alaska to Ottawa, which is just north of New York State.

His mom rode with him for the first 1,200 miles.

Then he joined up with other young riders, arriving for a rally on Parliament Hill in late September.

“I’m 17-years-old, and that means I’m too young to vote. But I believe I should have a say in decisions that are made on this Hill because when Parliament makes decisions about climate and energy, its people my age – people who are too young to vote – who will live in the world determined by what decisions made.”

(applause)

About a dozen members of Parliament and maybe 50 cyclists showed up for the rally. Boothroyd talked to hundreds more as he rode across the country.

He says he wasn’t just doing it for a good cause, he was doing it to protect his home.

“You’re very protective over wherever you grew up, and the place you know very well and love, so if you see a threat to that, you want to do everything you can.”

Now, Boothroyd is a regular twelfth grader again.
But unlike most, he’ll be keeping a close eye on the climate change talks taking place in Copenhagen in December.

He’s hoping his effort convinced the Canadian government to do more.

Destructive Beetle Creates Blue Wood

For more than a decade, mountain pine beetles have been devastating

For more than a decade, mountain pine beetles have been devastating

forests in Canada and the Western United States. Colorado
has been hit especially hard. Millions of dead pines are creating the potential for huge forest fires. So, the trees are being cut
down. Conrad Wilson reports, some business are using that
timber:

(sound of a beetle)

That’s the sound of mountain pine beetles hard at work, laying
eggs beneath a tree’s bark. That kills the tree.

Here in Colorado’s Rocky Mountains,
two million acres of pine trees have been killed.

But the same destruction caused by the bugs has also created an
opportunity.

The beetles introduce a fungus that stains the wood a unique
blue. And that’s caught the attention of Colorado’s woodworkers. They’re using the wood for everything from furniture to decking.

(sound of sawing and pounding)

Outside Boulder, a company called Kitchens by Wedgewood is using the wood for
cabinets.

Wedgewood President Jim Ames says his company started working
with the timber three years ago.

Despite the drop in the housing market, Ames says customers like the blue stained finish.

“People are starting to ask for it more and more. Again, as
we get into this green movement, everybody wants to see what all those
dead trees in Colorado look like when they’re turned into a cabinet door.”

Ames says, with so many trees being killed, there will be enough timber to make beetle
wood cabinets for the rest of his lifetime.

Commercial Fishing Gets Failing Grade

A new study out in the journal Nature grades countries on their ocean
fishing practices. Rebecca Williams reports even the top countries are not
getting a passing grade:

The US, Canada, and Norway are some of the countries doing the best job.
That means they’re fishing in a responsible way.

But they all come in at 60%. That’d be a D, maybe a D-plus.

Tony Pitcher is the main author of the study.

“Wasn’t very encouraging actually that even the top scoring countries were
not really that good. So it wasn’t anything to write home about – we were
at the top but it wasn’t a great field. At the bottom end some countries
were just disastrous. More than half the countries didn’t even pass the
40%.”

Countries are getting bad grades because there’s a lot of over-fishing going
on. There’s illegal fishing. And there’s a big problem with nets and traps
getting lost. They can snare marine mammals, birds and fish.

Tony Pitcher says it’s not always easy to know where your fish came from.
But he says you can look for a blue and white label when you’re shopping.
It’ll say Marine Stewardship Council on it.

Obama: Tar Sands Oil Will Work

President Obama indicates a willingness to continue to import Canada’s dirtiest source of oil. Lester Graham reports environmentalists don’t like it:

Transcript

President Obama indicates a willingness to continue to import Canada’s dirtiest source of oil. Lester Graham reports environmentalists don’t like it:

The United States gets about 20% of its imported oil from Canada. Half of that comes from tar sands in Alberta.

It takes two-tons of the asphalt-like substance to produce one barrel of oil.

Refineries in several states are expanding facilities to process the dirtier oil.

Henry Henderson is with the Natural Resources Defense Council.

He says takes a lot more energy to extract, transport and refine tar sands oil. That means a lot more greenhouse gases.

“At least three times what conventional oil involves. That brings with it a significant threat and impact on our national security in terms of changing global climate in a way that is a threat to us.”

Despite the environmentalists’ concerns, President Obama says the U.S. will work with Canada to use the tar sands oil reserves.

Nature on a Concrete Canvas

  • Artist Christopher Griffin, the owner of the house, uses a long smooth bone to draw a picture after each swipe of the trowel (Photo by Karen Kelly)

Sometimes cities can seem like drab, impersonal places. But every once in a
while, you see a building that stops you in your tracks. Karen Kelly tells a story about a house designed to do just that:

Transcript

Sometimes cities can seem like drab, impersonal places. But, every once in a
while, you see a building that stops you in your tracks. Karen Kelly tells a story
about a house designed to do just that:


(sound of construction and trucks)

When you first see it, you’re just not sure.

A two-story house is being covered with marks etched in concrete.

Is it intentional? Or just a layer of construction?

Then you see a large black figure on the west side of the house and realize- oh, it’s
a whale. Waves are etched in the concrete around it. Walk around the corner and
you see flocks of birds flying over roughly drawn buildings.

(sound of scraping)

And just past the birds, there are three men working silently on a platform. Two
are spreading layers of fresh concrete.

The third is artist Christopher Griffin, the owner of the house. He uses a long
smooth bone to draw a picture after each swipe of the trowel – and before the
concrete sets.

He says he has to work fast.

“They would scrape the mud on and I would be going around them, over top of
them, actually right behind their trowel and there’s no chance to stand back; there’s
no chance to second guess.”

Griffin has been a professional artist in Ottawa, Canada for almost twenty years.

Griffin’s motivation was simple: his house really needed a new exterior. But the
regular stuff that people put on their houses didn’t feel right to him.

Instead, he thought he’d try some drawings like he’d seen in a photo of mud huts in
Africa.

“It was irregular; it was organic; it wasn’t pristine; it wasn’t crisp; it wasn’t
heartless. And that sort of quality was something I was after.”

(sound of chatting and scraping)

But while Griffin had this vision of giant sunflowers and caribou, contractors had
no idea what he was talking about.

Several told him it couldn’t be done.

Dan Charette is part of a team that was willing to give it a try.

“It’s a fantastic opportunity to bring our craftsmanship to a different level. There’s
a whole other creative level to what we do here with constructive behaviors, so it’s
really a lot of fun.”

For instance, the contractors suggested adding fly ash to the cement. It’s a
byproduct of burning coal and it also makes the cement more elastic.

Griffin liked that it was more environmentally friendly.

He also recycled building materials and added solar panels. But usually that’s not
what people see.

He says what really makes him feel good is when people just stop and stare.

“Absolute strangers stopping their cars, getting out and having a look. There’s a
teenage skateboarder who stopped and said, ‘Wow, awesome house.’”

Griffin says, in that way, his house has become a public space.

In fact, he argues everyone’s house is a public space.

And he suggests people think about what they want their house to say to someone
walking by.

Part One: Canada’s Take on Trash

  • Jen Spence's collection of trash/ recycling containers on the east side of Toronto. The city has retooled its recycling program in recent years to make it easier for residents.

Sometimes it takes a little public
embarrassment to get on the right track.
Back in 2000, the city of Toronto couldn’t

Sometimes it takes a little public
embarrassment to get on the right track.
Back in 2000, the city of Toronto couldn’t
find a place to send its garbage – so it
started trucking trash across the border
to the US. Julie Grant reports that inspired
Toronto to create one of the most aggressive
recycling programs in North America:

Some days Toronto has sent as many as 150 trucks full of
trash 300 miles to a landfill in the U.S. For those of you
counting at home, that’s 90,000 highway miles a day. That’s
not only bad for the environment. As gas prices have risen,
it’s also bad for Toronto’s bottom line.

But the bigger issue was Toronto wasn’t taking care of its
own trash. It wasn’t even keeping it in Canada. It was
trucking it to Michigan.

And the people in Michigan – they didn’t like it too much.

They’ve complained about the stink of Toronto’s trash for
years.

They even got the U.S. Congress to look at ways to stop it
from crossing the border.

But, free trade even covers a commodity such as garbage.

The people in Toronto are a little embarrassed by it all.

(sound of a neighborhood)

David Wallett looks perfectly pleased with the landscaping in
his small lawn in east Toronto. But his eyes tilt downward
when he’s asked about shipping the city’s waste to Michigan.

“The downside of that is all those trucks ripping down the
401. I mean that can’t be good for the environment to have
lots of trucks burning gas just getting it there.”

But the City of Toronto had signed a contract with a
Michigan landfill. So the trucks kept ripping down highway
401, even as fuel costs got higher and higher.

Geoff Rathbone is Toronto’s general manager of solid waste.
He says the contract is a dark cloud – but it got the city and
residents on-board with recycling.

“The shipment to Michigan really became a wake up call that
allowed us to set very aggressive waste diversion targets.
And to realize that what we were shipping out of our country
was really more of a resource than a waste.”

Rathbone says Toronto set a tough goal – to reduce the
waste stream by 70%. And the city put up nearly a half-
billion dollars to do it.

But a funny thing happened as they started increasing their
recycling stream. Oil prices kept rising. That meant
commodity prices kept rising, too. Metals, plastics, and
paper have started to gain real value. Recycling paid!

And Toronto kept re-tooling its recycling program to make it
really easy for people.

(sound of a neighborhood)

On the east side of Toronto, Dick Wallett and his neighbors
each have one of those huge cart-like garbage barrels – the
ones with a handle and wheels. But it’s not for trash. It’s for
recyclables.

Jen Spence says it’s much easier than it used to be.

“For awhile it was very complicated. We had to put
newspapers in one bin and glass and bottles and jars in
another bin.”

Now they just throw everything into that one big container
and wheel it to the street. The city picks up and sorts the
recyclables. For free. It also picks up compost. You know,
food waste. Spence takes out a small pail from under the
kitchen sink to show me. It’s latched shut.

“This is the green bin. The city of Toronto sends this out to
anyone who’s going to be producing garbage. It collects
flies really badly, and it’s hard to clean, so they send out
these bags that are perfectly for it. It’s a nice size. It fills up
pretty quick and doesn’t stink. We used to have a huge can
and now it’s just that little guy that goes out every two
weeks.”

The city makes it kind of hard to take out regular trash –
things that can’t be recycled or composted. Like Spence
said, it’s only picked twice a month. And you pay as you
throw. The more you make, the more you pay.

Toronto has been able to cut the number of trucks headed to
the landfill in Michigan in half. And it’s moving toward it’s
goal of reducing the waste stream by 70%.

The city even plans to make energy out of the compost it’s
collecting.

The city plans to generate electricity and eventually make a
biofuel from the compost. That will be used to run Toronto’s
trucks to the landfill.

Oh, but those trucks won’t be going to the landfill in
Michigan.

The city has finally found a Canadian landfill that will start
taking Toronto’s waste in 2010.
