Farming the White House Lawn

Some people think American agriculture needs a makeover. They question why we waste so much fuel moving food long distances. A growing movement is calling for farmers and everybody else to produce more locally-grown, organic food. Shawn Allee reports some people want the President to set a good example:

Transcript

Last October Michael Pollan published a letter to the President in the New York Times.
Pollan is a sort of agricultural policy gadfly. His open letter to the President was full of big, policy-wonkish ideas about how to encourage local food production. But Pollan also wrote one small suggestion. NPR’s Terry Gross picked up on it.

GROSS: “You would like the next president to instead of having a White House lawn to basically have a White House garden. The president would set an example for the rest of us by having this garden of locally-grown foods?” (laughs)

POLLAN: “Now why is that preposterous, Terry? I mean, that’s actually one of the more practical things I proposed.”

Pollan went into how the President could even share some of his veggies with food banks.

POLLAN:” So you have this powerful image of the White House feeding Americans. What could be better than that?”

Some people heard this interview or read Pollon’s article and thought, “right on” – there should be a White House farmer. One family from central Illinois was especially intrigued. Terra Brockman talked about it with her father and sister.

BROCKMAN: “Well, it’s a great idea, but why don’t we bring it down to earth and make it real?”

ALLEE: “So, basically you translated it into reality by creating a contest on a Web site. White House Farmer dot com, as I understand it.”

BROCKMAN: “Yeah, we figured it was a way that we could get it out nationally without much time or money and ask people all across the country, ‘who do you think would be a good White House farmer?’ and have people nominate their farmers.”

Now, Brockman built her contest Web site even though President Obama never even talked about the idea of a White House farmer. But she’s hopeful because the White House actually has an agricultural past. At one time sheep grazed on the White House lawn, and during World War II Eleanor Roosevelt grew a Victory Garden there.

BROCKMAN: “It’s not like this is so, so way out there. And really, whatever the President does is pretty symbolic and people do pay attention.”

People paid attention to White Houser Farmer dot com, anyway.
The site gathered around 57 thousand online votes in just a few days.
And exactly who is the unofficial new White House Farmer?
That would be Claire Strader, from Madison, Wisconsin.
Strader invited me to see the land she works.

STRADER: “We’re at Troy Gardens. It’s in a parcel of land in the city of Madison, on the North Side. I haven’t actually seen the farm for a few months because the snow’s been so deep.”

ALLEE: “Can we get closer to the farm area?”

STRADER: “Yeah.”

Strader is the head farmer at Troy Gardens. She trains city people to grow food here. She also makes the soil fertile through organic growing techniques.

STRADER: “You can just start to see now, the green flush over the whole field. That’s our cover crop of rye. It looks really good. I’m happy to see it.”
ALLEE: “Could you tear yourself away to go to DC and leave all this behind?”
STRADER: “It would be difficult to pick up and leave it behind, but it would be a tremendous honor and a lot of potential to spread the good word of organic agriculture and the positive impacts that would have on our country in the future. It would be hard to accept and hard to reject.”

Even with a White House Farmer chosen for him, President Obama still hasn’t said anything about the idea.
But Strader says she and some top contest vote-getters are trying to sway him – even if he’d pick someone else to run his garden.
Strader says she loves the idea of cucumbers and zucchinis growing at the White House… even if she’s not there to pick them.

Growing a Garden on Your Garage

David Lanfear recently ‘installed’ one on his own garage roof, so his neighbors could see the benefits (Photo by Joyce Kryszak)

When most people put a new roof on
their home they usually use standard asphalt
or tile roofing. But other people are going
for something more natural. They’re planting
grass and flowers on their houses. Joyce
Kryszak talked with one builder in
Western New York who planted a green roof on
his garage to show his neighbors how it works:

Transcript

About 90% of all residential roofs are made out of manufactured
asphalt.

But builder David Lanfear knows that nothing tops mother nature.
He makes roofs out of gardens.

Lanfear recently ‘installed’ one on his own garage roof, so his
neighbors could see the benefits. There are beautiful flowering
plants visible over the edge of the flat roof. Lanfear says they’ve got
the whole birds and bees thing going on.

“We’ve noticed a big increase in insects, butterflies, birds all
sorts of new birds that I haven’t ever seen. They’re up there
eating something. Bugs? But its kind of nice to sit on the deck
and watch this nature in the city thing,” said Lanfear.

But the living roof isn’t a novelty. Lanfear says the roofs are more
eco-friendly. He says a living roof provides a whole cascade of
environmental benefits.

“Especially in a downtown when you get a hard rainfall the water
washes off all at once. There’s nothing to absorb it. If you had
a roof like this it absorbs the water and let’s it off slowly. So, it
not only slows the runoff, it cools the water and it starts to filter
the water. It filters some of the atmospheric crud out.
Otherwise, you get super heated water rushing off into the storm
sewer, and then out into the river or the lake and effecting the
environment there,” said Lanfear.

Once his neighbors understood the concept, they stopped thinking
Lanfear was crazy. A few even offered to give him a hand planting
his roof.

First the roof was reinforced with used lumber. Next are the
waterproof barriers – a rubber membrane, a root barrier made out of
old billboards and some old carpeting. Finally, recycled, crushed
concrete is shoveled on to be used as soil for the plants to grow in.

It’s all sustainable. And the native plants require very little water or
maintenance.

Neighbor Deborah Bach loves to garden. So, she was happy to
pitch in. Bach says the concrete soil needs to be doctored to enrich
it. But they have a reuse idea for that too.

“My son works at Starbucks and they give out free grounds for
gardens. So, we’re going to try doing that to try to balance this
out. You know, using recycled materials and things that have
already been used,” said Bach.

Another neighbor stopped by to help. Alex Sowyrda is a high school
technology teacher who’s interested in the science of green roofs.
He plans to share what he learns with his students.

“I try to bring it into my curriculum at school and, hopefully, the
kids graduating high school now take this knowledge with them
and are able to make responsible choices in the way they build
and the way they design in the future,” said Sowyrda.

The living roof builder David Lanfear says it’s a concept that can grow
on anyone. Even people who grew up with more traditional roofs. He
says to start small – with a garage roof – or maybe even smaller.

“We all have little expanses of roof in front of windows. And in
the summer you might notice that when the window is open the
hot air blows in, a lot of that heat comes from that little bit of
roof. If we could just put sections one square yard of living roof
outside of our windows on the porch roof, that would make a
drastic difference in cooling our house – simple,” said Lanfear.

And pretty cheap. Lanfear says the cost of materials is about the
same as an asphalt roof. But he says there’s savings in the long run
because the green roof can last three times as long.

And he says it’s a whole lot nicer to look at.

Saving Nation’s Seed Supply

Multinational corporations started taking control of seeds around thirty years ago. Now, ten corporations own over half the world’s commodity seed supply. (Photo by Scott Bauer, courtesy of the USDA Agricultural Research Service)

Some small gardening businesses
are noticing more customers want organic
and heirloom seeds. Experts think that
trend might be important for the world.
Kinna Ohman reports they believe
those seeds might be the hope of future
food supplies:

Transcript

John Meshna points to a half empty rack of vegetable and flower seed packets in his
store.

“We’ve emptied this thing at least a half a dozen times this year. I thought maybe
we’d have a rush in the spring and that’d be the end of it. And it looks like it’s
going to be going through the winter.”

Meshna owns and runs DirtWorks – a green garden supply business in New Haven,
Vermont. He’s been selling organic and heirloom garden seeds for more than twenty
years. Heirloom seeds come from vegetables that have almost disappeared. And Meshna
thinks people want those types of seeds more and more because they’re worried about our
food supply.

“People call us just to make sure sometimes before they order, now, ‘these are really
organic seeds, right?’ Yeah, it says it right on the label. It’s gonna make you very
happy when you get that package.”

And it’s making certain experts happy too.

Hope Shand is the research director of Etcetera Group. It’s an organization that’s
concerned about corporate control of the food supply. Shand says when more home
gardeners and small farmers grow plants from organic and heirloom seeds, that helps
keep variety in the world’s food supply.

“This is an incredibly important service. People, gardeners, small farmers, urban
gardeners, are conserving, and saving seed diversity. No one else is really doing that
job.”

Hope Shand says multinational corporations started taking control of seeds around thirty
years ago. Now, Shand says, ten corporations own over half the world’s commodity seed
supply. And she thinks that’s risky.

“The seed is the first link in the food chain. Whoever controls the seed literally
controls the world’s food supply. We can’t afford to have the level of vulnerability
and dependence that that entails when we have a handful of multinational seed
companies controlling the world seed supply.”

(sound of watering)

“I’m growing greens without heat.”

At a small organic nursery in Hinesberg, Vermont, Julie Rubaud is one of those who
wants to get these seeds and plants to more people. For her, it’s not just preserving a
strain of a vegetable, it’s trying to match up those plants with the right gardener.

Rubaud grows close to eight hundred varieties of organic and heirloom plants for her
customers. She says that helps her connect people with the right plants for their gardens
and tastebuds.

“I always start out asking, ‘how much room do you have?’ And then I ask them
how they like to eat tomatoes. It’s nice to be able to cater everyone’s garden plan to
their individual needs because we have so many varieties.”

And if next year’s anything like last year, Rubaud will have at least forty varieties of
organic tomato plants ready for new gardens by next spring.

She wonders – with the economy the way it’s been – if one plant might do exceptionally
well.

“There’s Radiator Charlie’s Mortgage Lifter Tomatoes. Have you heard of that
one?” (laughs)

Radiator Charlie’s tomato has been around since the 1940s. You probably won’t find it
at the big-box discount-store gardening department. It’s one of those colorful, hardy,
productive plants that many people think will help bring back variety to our food supply.

Lead Soil in Urban Gardens

More Americans have started
planting their own gardens in recent
years. But it turns out a lot of
urban gardens are contaminated with
lead. Julie Grant reports:

Last year 22% of Americans planted a garden.

Wendy Heiger-Bernays is professor of environmental health
at Boston University.

She says if you have an urban garden, she would expect to find heavy metals, especially lead, in the soil. It comes from old garbage, dripping oil, and peeling paint.

“Older homes have been demonstrated to leach lead from the home through the drip line and into the soil.”

Even small amounts of lead in the blood can cause learning disabilities in children.

Heiger-Bernays says you don’t have to throw away this year’s veggies. Just wash them well. And peel root vegetables.

And to get ready for next year, Heiger-Bernays says have your
soil tested. If there’s lead, add a foot of clean compost to the top of the garden bed. Next Spring plant only in that top layer.

Growing Food – Not Lawns

Many environmentalists knock the suburbs. They don’t like how

dependent suburbs are on cars. They don’t like the sprawl, the large

houses and huge lawns. They think it’s a waste of land. Ashley Gross

Many environmentalists knock the suburbs. They don’t like how

dependent suburbs are on cars. They don’t like the sprawl, the large

houses and huge lawns. They think it’s a waste of land. Ashley Gross

reports… one woman is on a campaign to see some of those expansive

lawns turned into something a little more productive:

(sound of movie music)

Ever since soldiers returned from World War II, the suburbs have been portrayed as
the family-friendly ‘good life.’

“And so they joined the stream of family life in the suburbs. Soon to become part of
its familiar sights. Soon to absorb its familiar sounds.”

One of the most constant of those familiar sounds is a lawnmower.

(sound of lawnmower)

That noise just grates on Aileen Eilert’s nerves. Her goal is to live a more
environmentally-friendly life in the suburbs.

(sound of opening door and walking outside)

She does have a lawn. But she and her husband are converting much of it to
vegetable garden plots.

“So I have some snow peas growing here and here’s you know four tomato plants
and Bruce planted some peppers all the way down here.”

Eilert says gardening means she drives less often to the grocery store – and she’s
not buying produce shipped in from a different continent.

That’s important to her. Eilert says she decided to use less oil after her nephew was
killed in Iraq in 2005.

“You know, we’re fighting over there and it was about oil, and so I just thought I’ve
got to do something. I mean, it’s too late for me to do anything about my nephew,
and he was such a good kid. I’d like it to be where people – oh we don’t need to buy
oil from countries that may not be friendly to us or may not be stable.”

Eilert is not alone. People in the suburbs are beginning to think about their lifestyles
in a different way.

Evan McKenzie is a professor at the University of Illinois-Chicago He researches the
politics of suburbia.

“The stuff that was planned and put in place in the 60s and 70s and even the 80s, I
think in some cases is giving way to new ideas. I mean they’re selling and giving
away rain barrels in the suburbs so people collect rainwater to water their plants
with. I never heard of that before.”

Not everyone is onboard with the environmental movement in the suburbs yet. Last
year Americans spent almost 11 billion dollars on do-it-yourself lawn care just to
keep the grass green.

Aileen Eilert wants to change that. She calls her new campaign “Grow Food, Not
Lawns.”

Her approach is one-on-one. Today she’s pulling a plastic wagon loaded with
tomato and pepper starter plants. She’s headed for the subdivision one block over.

(sound of wagon)

Eilert approaches Tim Lakis as he mows his lawn. He gives him a pepper plant.
Then comes the pitch.

Eilert: “Lawns actually use a lot of chemicals if you put chemicals on your lawn and
that gets into the water system.”

Lakis: “Okay.”

Eilert: “And then also your lawn mower has way more emissions than a car would,
not that I’m saying that…”

Lakis: “Okay, I’ll look it over.”

Aside from some strange looks, that went pretty well.

But Eilert learns pretty quickly there’s way more gardening going on here in this
neighborhood she thought. She’d pegged it as a lawn-addicted wasteland. But this
subdivision’s residents are kinda green.

Eilert: “I assume you use a gas mower?”

Man: “No. Electric.”

Eilert: “Do you? Oh you are just the perfect person to talk to today.”

Woman: “I mean, every year I grow my tomatoes and peppers and zucchinis.”

Second Man: “Every year I try to get rid of more grass and put in more plants.”

Eilert even gets a recipe for cooking dandelions. She leaves the subdivision
encouraged.

“People were concerned and people did think it was a good idea to have gardens
and they’d be willing to make a little more of a sacrifice to make the earth a little bit
better.”

She’ll be visiting more subdivisions soon, trying to get more people to turn those
suburban lawns into gardens. And maybe get them thinking, just a little about other
things they could do.

Big City Recycles Rain Water

Rain barrels are catching on as a simple way to capture water for the
garden. Some people are going even further to save water. They’re piping
rainwater into their indoor plumbing. Ann Dornfeld reports:

Transcript

For years, the rain that fell upon Seattle’s city hall vanished almost as soon
as it hit the roof. It gushed down to the street and washed away oil and
heavy metals left by passing cars. In minutes, the rain became toxic waste
that flowed into the city’s waterways.

These days, Seattle’s new city hall doesn’t let rainwater slip away. This city
hall puts rainwater to work.

(Sound of toilet flushing)

City Councilmember Richard Conlin demonstrates one of the building’s
rainwater-filled toilets. It looks perfectly normal. Conlin says that’s not
always the case:

“It actually does get discolored, particularly during the leaf season, or
when the rains first start in the fall. And so for a while we had notices
in the bathroom saying ‘don’t pay attention to the fact that this water
is discolored. It’s because it’s recycled rainwater.’ But I think people
have really gotten used to it now.”

Rain that doesn’t get absorbed into City Hall’s green roof is channeled to a
million-gallon tank in the basement. It goes through a series of filters, then into the pipes. It’s called a rainwater catchment system.

“Right now we’re using it for pretty much all of the non-potable
functions that we have in City Hall. It’s probably good enough quality
to use for potable functions, but we aren’t going to go there because
we have great water that we get in the city and we’d have to do some
treatment in order to meet legal standards.”

Conlin says the city installed the rainwater system as a way to
practice the conservation that city leaders preach.

Bob Scheulen is a member of the choir. When he and his wife built their
house several years ago, they built a hollow concrete patio that stores
7,000 gallons of rainwater.

Scheulen says despite Seattle’s rainy reputation, droughts are common in
the summer:

“Basically there’s two choices if people want to continue to
use water as the population grows: the city can either build a lot more
reservoirs and drown more land or people can conserve water or be
their own utility for those summer months.”

Scheulen lifts a metal hatch on the patio floor and sticks his head inside:

“I bet we can see how full it is right now. Oh, it’s gettin’ pretty full. It’s
probably 60% full. A couple more
rainstorms and it’ll be probably completely full.”

The family’s washing machine uses rainwater, and they flush their toilets
with it. But Scheulen says what uses the most water is the garden:

“This year we did not run out of water but last year I got a little
overzealous in watering my flowers and I did run out. (Laughs)”

Mike Broili says that kind of awareness is exactly what most Americans are
missing. He runs Living Systems Design, and he installed Bob Scheulen’s
filtration system. Broili says he learned how much water he uses when he
lived in a cabin in Alaska. He hauled his own water for 15 years:

“And when you have to carry your water, you become really
sensitized to how much you’re using and how you use it and where
you use it.”

Broili says you don’t need to live in a rainy climate to run your home on
rainwater:

“There’s enough water that lands on the roofs even in the Southwest
to supply their needs.”

Broili admits the rainwater catchment systems he builds are pricey: 1500 to
15,000 dollars. But he says his clients recognize the value of water:

“Of all of the water on the planet, and this is a water planet, 7/1000ths
of it is actually available for human consumption. That’s a tiny, tiny,
tiny portion.”

Broili says as the population grows, pretty soon the only affordable way to
get water will be from the sky.

Harnessing the Power of Permaculture

Jan Spencer (pictured) removed his driveway to make room for more landscaping features. This is part of the concept behind "permaculture," the practice of using resources on-site to fulfill as many needs as possible. (Photo by Ann Dornfeld)
Spencer's next door neighbors, the Finneys (pictured) say they'd like to make their home more energy efficient. Spencer suggests closing their covered back porch with removable clear panels. (Photo by Ann Dornfeld)

The word “suburbia” conjures up sprawling developments, huge lawns and
long commutes. It’s not the most eco-friendly arrangement. Jan
Spencer lives in the suburbs and he wants to change their reputation. His
version of home improvement is making his quarter-acre property as
energy-independent as possible. As Ann
Dornfeld reports, Spencer calls the process “suburban renewal:”

Transcript

When you get to Benjamin Street, you don’t need to look at house
numbers to find Jan Spencer’s place. His is the one with a jungle of berry
vines instead of a yard. Oh, and if you drove here, you’ll need to park on
the street:

“I removed my driveway early on when I moved here because I didn’t
need space to park five cars. So I took my driveway out and I kept a lot of
my driveway to make landscaping features!”

Spencer stacked pieces of the broken driveway to line two ponds. He
collects rainwater in a huge tank out back and fills the ponds with it:

“But that’s a habitat! There’s pollywogs in there, there’s fish in there, there’s
little water skimmers.”

This is more than just funky, utopian landscaping. It’s permaculture. That’s
the practice of using natural resources found on-site to fulfill as many
needs as possible. Permaculture takes the trend of “buying local” up a
notch. You don’t just eat organic asparagus grown 20 miles away, or heat
your home with wind energy from across the state. You produce those
things yourself, at home.

Even in a vinyl-sided tract house in the suburbs, Spencer says, there are still
plenty of natural resources available:

“Soil… sunshine… and rainwater.”

And, he says, multi-purposing can make the most of the space available.
For instance, Spencer converted his carport into living quarters for
roommates. That creates a higher-density living arrangement. Next, he
plans to grow watermelon or squash on the roof.

“When you really start looking around a location with a set of
permaculture eyes, ‘How can I use this space most effectively?’ even
familiar places take on a really different kind of an appearance.”

Spencer knows not many people are willing to tear out their driveways to
have more room for raspberries, but he says there are plenty of simple
ways to harness a suburban home’s energy potential. Solar panels on his
roof heat his water for the warm half the year. Low-tech systems work, too,
like composting and watering the garden with a can instead of soaking it
with a hose or sprinkler.

To see which of Spencer’s suburban renewal methods might work for the
average family, we go next door to visit the Finneys. Dan is a firefighter.
Eden stays home with their young daughters, Peyton and Madison. The
girls like to raid Spencer’s berry patch. But the Finneys are pretty fond of
their grass lawn. Their minivan and RV are parked in the intact driveway.

Eden says the couple does want to make their home more energy-
efficient, but for different reasons.

“For him, definitely it’s cost. But for me, the environment plays a big part in
it.”

The Finneys already grow fruits, vegetables and herbs in raised beds out
back. And they installed energy-efficient windows:

“It knocked our bill down considerably this last winter. That was a good
thing to do for us.”

Spencer and I wander out to the Finneys’ covered back porch. Spencer
says the Finneys could close it in with removable clear panels to lower
their heating bill even further:

“The solar orientation here is perfect. So part of the year it’d be totally
open like this, and part of the year this place could actually be helping to
heat the house.”

“Huh. Didn’t even think about that!”

Spencer says the trick is to look at under-utilized spaces, like the
boundaries of the Finneys’ property:

“And having some kind of grapes, kiwi fruit, some type of edible vine
growing along the front of that fence.”

“We talked about doin’ that and we will do that. We’re gonna build a trellis
there. I just haven’t got around to it. As you can see, this is the project
house. And we do want to grow some kiwi. And they can grow really fast.”

Spencer’s ideas are going over pretty well, so he decides to go out on a
limb.

“Okay, I’ll just suggest something. What would you think of the idea of
having a 1600-gallon water tank up on blocks there to help water your
garden?”

“No.”

“Maybe one behind the shop, and do the same kinda thing back there
where it wouldn’t be in the middle of our yard.”

“Ah, okay, so it’s the idea of where something like that would be.”

“Probably. Yes.”

“Yeah!”

Spencer needs this kind of feedback as he gets ready to take his
suburban renewal philosophy on a speaking tour. He’ll be talking to
longtime permaculture activists as well as more mainstream suburban
residents who just want to make a dent in their utility bills.

Road Salt Damage

Overuse of salt can cause damage to concrete, steel and the environment. (Photo by Lester Graham)
Liquid salt (brine) works more quickly than road salt and ultimately means less salt in the environment. (Photo by Lester Graham)

Each year about 118,000 people are hurt and 1,300 people are killed on
the roads during snowy and icy conditions. So, snowplows hit the
roads, scraping snow and ice off the surface… and spreading
incredible amounts of salt on highways, streets and roads to help keep
them clear. Lester Graham reports there’s some concern about the long-
term effects of all that salt:

Transcript

This dump truck is getting ready for a load of salt for a coming
winter storm. Salt helps make icy roads safer. It helps prevent
people from slipping and falling on sidewalks. And… it’s pretty
cheap. But there are problems with salt. Salt pollutes and salt
corrodes.

Mark Cornwell has spent a good deal of his career trying to convince
highway crews that there are better ways to keep things safe and reduce
how much salt is dumped on roads and sidewalks:

“Salt basically damages just about everything it comes in contact
with. Salt moves through concrete and attacks structural steel,
bridges, roads, parking structures; it eats the mortar out of bricks
and foundations. It damages limestone, you know, just on and on and
on.”

So, even though salt is cheap, the damage it does costs a lot. It’s a
hidden cost that’s seldom calculated. Imagine the cost of having to
replace a bridge five years early because the structure is weakened by
salt. And then there are your direct costs: trying to keep salt
washed off your vehicle, and still seeing rust attack your car.

Cornwell says there are some cities and road commissioners working to
reduce the amount of salt spread on the roads. But in most places, the
political pressure to get the salt trucks out early, and laying it on
thick to keep drivers happy, outweighs any concerns about trying to
reduce the salt:

“I’m sure the public expects full attention to snow and ice. And they
have absolutely no understanding, however, of what it costs to provide
that.”

Nobody thought a lot about the damage salt was causing until the last
couple of decades. In a few places, the people responsible for keeping
the roads and walkways safe have been trying to reduce the amount of
salt they use and still keep public safety tops on the list of
concerns:

“So, this is our shops. The brine-maker is right here.”

Marvin Petway is showing me some of the tools in his arsenal to reduce
how much salt is used and still keep things safe. He works at the
University of Michigan, where there’s a goal to cut the amount of salt
used in winter in half. What they’ve learned is using innovative ways
of putting down salt can actually help melt snow and ice faster. One
way is to mix it with water to get the chemicals in salt working
a little more quickly:

“Why use 5 pounds of rock salt when you can use 2 gallons of liquid
salt? We’re able to get better coverage, quicker, better cost, and
we’re putting the material that is effective in reducing ice build-up
directly to the area where we don’t want ice located.”

The crews trying to reduce salt use computer assisted spreaders to
measure out only the salt needed, they mix in less corrosive chemicals
that make salt brine more effective, and even just wetting the salt in
dump trucks with chemicals all help to melt snow and ice faster and in
the end use a lot less salt.

Nothing is going to replace salt altogether, but those efforts can add
up to a lot less salt. That means less destruction of infrastructure.

But there are more reasons for reducing salt than the damage to
roadways and parking decks. Salt also damages the environment:

Mark Cornwell first noticed the effects of salt because he was a
horticulturalist. He’d work all spring, summer and fall planting
shrubs, make the grass green, tending beds of flowers. Then the winter
would come:

“Unfortunately what we were doing in six months of winter was
undoing everything we did in the other six months of the year.
If you’re going to get ahead, you’ve got to solve the problem
and in my mind, that was misuse of salt.”

Use too much salt and it kills plants. And it turns out the cost of
using all that cheap salt could be even greater than anyone guessed.
For decades, it’s been assumed that rain washed away most of the salt, but
studies in Ontario find that a lot of the salt doesn’t get washed
away.

Instead, a good deal of it is percolating down into shallow aquifers.
Researchers predict that in the future we’ll start find salt is getting
into the groundwater that supplies many of the wells where we get our
drinking water.

For the Environment Report, this is Lester Graham.

Tossing Food Scraps to the Worms

Every day we have to deal with throwing away
garbage. For most, that means taking it to the curb.
But some people keep the food scraps for something
special. Richard Annal has the story of a
family that’s using a money-saving, all-natural way
to dispose of food waste:

heard about for years but have never actually seen. And she’s doing it in her basement. She’s taking her
family’s food scraps and feeding them to worms downstairs. Brenda
Lotito’s home is white and brown, and sits on a little hill in a suburban
neighborhood. Brenda is expecting me and greets me at the door. Behind
her, there’s a little commotion. That’s her son John and the family dog,
Charlie.

I have a seat at the kitchen table. I find out it was John who first
took an interest in worms. He likes the red, slimy night crawlers:

“What sparked my interest in the worms is how they feel when you touch
them and how you can’t hold them very well because they keep slipping
out of your hands.”

With a little research at their local library, Brenda and John found
worms work as a natural garbage disposal. So for the past five years,
instead of putting the garbage out, they’ve been feeding the worms.
They turn the food scraps into compost.

We all head down to the basement, including Charlie, the dog. That’s
where Brenda keeps the family’s worm box.

The Lotitos have a typical basement. Washer, dryer, sports equipment…
and a box of worms. It’s wood. It’s about 2 feet wide by 4 feet long.
Brenda tells me they can be different sizes depending on what you need.
This one is more than large enough for Brenda, John, her husband, and
Charlie, the dog. Brenda says she can put just about all her food waste
into the box:

“I don’t put meat or anything like that in there but we put all our
vegetables. Ya know, I don’t have to cut anything up. I just simply
throw the corn cobs in there throw the husks in there. And they eat
it.”

I open the lid and peer in. The first thing I notice is what I don’t
notice. There’s no offensive odor. The only smell I do detect is that
of fresh earth. I move the contents of the box around. There’s some
shredded newspapers, some corn cobs in the process of becoming worm
food, coffee grounds, and other food waste.

After a little poking around, I find the worms: dozens of red,
well-fed looking worms. They’re fat.

Brenda tells me she has been making worm boxes for years and she thinks
others can benefit from her experience. She’s selling worm composting
kits for a small price. She says worm boxing is easy to get started,
takes a little investment, and the maintenance is low:

“Once you buy a batch of red worms, they’ll just keep on multiplying every
7 to 10 days, and um, you’ve got yourself a great composting bin.”

Brenda says worm box composting has a lot of benefits. In her town,
the trash pick-up service charges by volume. So, she saves money on her
garbage bill by putting most food waste into the box instead of the
trash can.

And she saves money on fertilizer. Brenda is a gardener. The compost
left by the worms is a great all-natural fertilizer. And in addition,
the worm’s, um, leavings work as a natural bug repellant as well:

“What it does is it makes the plant create an enzyme that is bitter to
aphids and other creatures.”

And Brenda thinks fewer chemicals and fossil fuel-based fertilizers
makes the food in her garden that much better:

“You know I can pick the tomato right off the plant. Ya know, wipe it
off, wash it off, And feel comfortable that I’m putting it in my mouth.
Everything has come from the earth. It’s a circle, it’s awesome.”

Brenda says to her, the biggest benefit of worm box composting comes
from letting people know there’s another way to dispose of food waste.
It’s all-natural. It means less garbage to pick up, less garbage to
fill up the landfill, and at the same time it saves money, provides a
superior fertilizer that’s all organic, and puts nutrients back into
the Earth… where they come from.

Cougars Creep Into Suburbia

Wildlife biologists say cougars are gradually moving from the Mountain
West into Midwestern states. Usually the large cats avoid people, but in
one suburban neighborhood residents are worried. They say they’ve
spotted a cougar in their backyards six times in the last two years. They’re
worried about their pets. They’re worried about their kids. Bob Allen
reports:

Transcript

On a June morning two years ago, David Hanawalt was hunched over a
flower bed in his back yard loosening the soil with a hand rake. He says
he caught something out of the corner of his eye moving toward him:

“I started to prepare myself because it seemed like a large dog that was
making a beeline for me.”

(Allen:)”As if it was going to jump on you?”

“Yeah. And as soon as I stood up and turned it veered off. And the way it
ran, the way it moved, and its ears, I swear it was a cat.”

The cat disappeared into a patch of brushy woods behind his
house. Hanawalt says he became more convinced it was a cougar when his wife, T, saw
a big cat with a long tail sauntering across a neighbor’s blacktop driveway.

“…And it was just walking up like this. Just walking up. And then it went
just right off into those woods. Casually. It wasn’t in any hurry.”

The creature’s nonchalance is what has people in this northern Michigan
neighborhood worried. Some of them have read David Baron’s book
Beast in the Garden. It recounts how people have built their houses in
foothills surrounding Boulder, Colorado, right into prime mountain lion
country, then they saw cougars coming into their yards, taking their dogs and cats.
Eventually, a cougar killed a high school boy when he was jogging on a
wooded trail outside Boulder.

There are significant differences between the situations in Colorado and
Michigan, but author David Baron says if people are seeing a cougar and
it’s not running away from them, and in fact begins to approach them, then
that can be a warning sign:

“That’s what was seen in Boulder in the years before there was a fatal
attack not too far from Boulder. That’s what was seen in Missoula,
Montana back in the late ’90s before a little boy was attacked who did
survive. But again, if there are multiple reports of what is clearly a cougar
in one neighborhood, it’s probably worth looking into.”

Back in the northern Michigan subdivision Patty Barrons lives in the
house at the end of the cul-de-sac. It backs right up to a stretch of woods.
She was walking up the street one early morning last August when she
spied a big cat heading into her back yard. She took off running for her
front door because she remembered she’d left her housecat on the back
deck:

“…And I ran through the house, and onto my deck and down the two steps.
And went, I can’t believe I did this, it’s so embarrassing but I went, shoo,
shoo.”

It didn’t shoo.

Instead, Barrons says, it turned and took two steps toward her. She took
two steps back onto the porch. Barrons describes the animal as
enormous. She says she and the big cat watched each other from a
distance of fifteen feet for about half a minute:

“The face when we looked at each other eye to eye I felt that I was looking
at, I mean I knew I was looking at a lion. I knew I was looking at a lion,
there was no doubt. It was very muscular. It never crouched down or
anything so I didn’t feel threatened. But it stared at me and then, um, it
turned and walked around my flower garden, behind the tennis courts
and kept going.”

Patty Barrons keeps a careful eye out when she takes her early morning
walks, and she won’t work in her garden in the early morning or
late evening hours anymore.

(Sound of model airplanes buzzing)

Next to her house is an open field where kids play soccer and neighbors
walk their dogs, and its where T Hanawalt’s sons fly the remote controlled
model airplanes they love to build, but she won’t let them go out by
themselves anymore:

“Day or night. I mean they used to run around this neighborhood and play
with all the children at night and we’re not doing that anymore. I just, I
can’t have that it’s too scary. In fact, I’m looking to move.”

State wildlife officials won’t come out to investigate unless there’s clear
evidence of what could be a cougar. That means a photo, a paw print,
maybe some scat or droppings from the animal.

The people in this neighborhood didn’t get any of that, but now they have
their cell phone cameras handy.
