A National Park might not be the first place
you’d expect to turn into a crime scene. But John Ryan
found one – of sorts – on a boat touring Alaska’s Glacier
Bay National Park:

(music)

Scene of the crime. Glacier Bay National Park. 9 o’clock on a sunny Saturday morning.

The crime: Global warming. You know: ice caps melting. Sea level rising. Deserts and
disease spreading. Scientists say it’s big, very big.

(music)

Intergovernmental investigators have ID’d the perpetrator: it’s us. Emissions from fossil
fuels like coal and oil have started heating the earth.

But here on the Fairweather Express II, you’d never know it. Park ranger Kevin Richards
is at the mic, entertaining passengers as we cruise past mile-wide glaciers
in the sun.

“That snow fell when Thomas Jefferson was signing the Declaration of
Independence.”

Richards tells the crowd how the glaciers have retreated 60 miles in the past 200 years.

But he hasn’t once mentioned global warming.

In the audience, Anchorage pathologist James Tiesinga smells a rat.

“The rangers seem very reluctant to say the words ‘global warming’, they skirt
the issue of why the glaciers are receding. I can’t help but wonder if the Park Service
has communicated the message to its employees, ‘don’t bring this up, it’s a hot topic’.”

And I notice the visitors’ newsletter put out by the park talks in depth about the changing
glaciers, but fails to mention that the climate is being changed by humans.

During a break in the naturalist’s stand-up routine, Tiesinga asks why there has been no
mention of global warming? Are we witnessing a coverup?

(music)

As huge chunks of ancient ice tumble into the bay, the Park Ranger, Kevin Richards, says, no,
there’s no censorship of climate science.

“Until very recently, yeah, if you’re working for the government, you
probably didn’t talk a lot about it. But now it’s okay, it’s an open forum right now.”

He says he’ll get to the connection
between melting glaciers and a warming earth near the end of his talk, but it’s a lot more
complicated than you might think.

“We just can’t talk about tidewater glaciers the same way we do about
terrestrial glaciers. It’s not the same process.”

Here’s why it’s not the same: tidewater glaciers have snouts that stick out into the ocean. Terrestrial glaciers are
land-locked. Richards goes on to say that land-locked glaciers in the mountains above
Glacier Bay are shrinking under a warming climate. But he says the dramatic loss of 60
miles of ice from Glacier Bay itself is not a sign of global warming.

(music)

To fact-check the on-board nature talk, I called up Roman Motycka.
He studies glaciers at the University of Alaska-Fairbanks’ Geophysical
Institute. He confirmed that global warming is hitting most Alaskan
glaciers hard.

“90% of the glaciers in South-Eastern Alaska are wasting away, and that’s
complicated, but primarily due to global warming.”

So why aren’t tourists in Glacier Bay hearing that when they witness fall
ice chunks fall into the ocean?

“It’s really complex there. Here’s what happened when all
that ice got lost.”

Motycka explains that tidewater glaciers have their own cycles of
advance and retreat. In a nutshell, when the snout of a glacier ends up floating in deep water, it becomes inherently prone to calving – that is, dropping icebergs – independent of the climate. And that’s what’s happened in Glacier Bay. So, in other words…

“Your naturalist was right, the terrestrial glaciers are the
ones that are more important to look at in terms of straight climate
change.”

(music)

Back on the Fairweather Express II, Park Ranger Kevin Richards
finishes his day at the mic talking about global energy consumption and
making a plea for people to protect the environment back home,
wherever they come from.

So in the end, park rangers are still the nature lovers in funny green outfits you might
remember from your childhood. And as this episode of Thaw and Glacier comes to a
close, all is well in Glacier Bay. Except for a little thing called…

(music)

…global warming.

Crop-Based Biofuels Increase Co2

  • Sodbusting underway in South Dakota. (Photo by Boyd Schulz)

The government’s new renewable energy standards call for a big boost in biofuels, like ethanol, to replace some of the gas we burn in our cars and trucks. But a new study in a recent issue of Science magazine says not all biofuels are created equal. If they’re grown on land that’s converted from natural prairie or forest, they could make global warming worse. Stephanie Hemphill reports:

The government’s new renewable energy standards call for a big boost in biofuels like ethanol, to replace some of the gas we burn in
our cars and trucks. But a new study in a recent issue of
Science magazine says not all biofuels are created equal. If
they’re grown on land that’s converted from natural prairie or forest,
they could make global warming worse. Stephanie Hemphill reports:

There’s a lot of buzz about biofuels. American farmers are planting
lots of corn, to be turned into ethanol. In Brazil, they make ethanol
from sugar cane, and they’ve replaced nearly a third of their gasoline
with it. In Malaysia and Indonesia, huge plantations grow palm oil for
bio-diesel.

But there’s a cost to these crops.

“In the top chunk of soil, we lose 40% of the carbon from that soil
when we convert it to agriculture.”

Joe Fargione says there’s almost three times as much carbon in
plants and soil as there is in the air. So when the soil is disturbed, it
releases carbon. When rain forests are cut to plant sugar cane, it
releases carbon. When peatlands are drained to plant palm trees, it
releases carbon.

Fargione is a biologist. He did the study for the University of
Minnesota and The Nature Conservancy.

According to his calculations, clearing land to plant crops releases
more carbon than we save when we burn biofuels instead of gas.

“It’s like taking out a loan and then trying to save money, but you
can’t save any money until you’ve paid off your debt. And the debts
are so large it’ll take decades or centuries for us to pay off that debt.”

We’ve released so much carbon into the air, it’ll take years to capture
it again.

Midwestern farmers are plowing land that was once set aside for
wildlife, to plant corn for ethanol. Fargione says that racks up a
carbon debt that’ll take about 90 years to repay. And cutting down a
rainforest takes even longer to recapture the carbon.

Farmers operate in a global market. So what Midwestern farmers do
can affect the Amazon.

Farmers usually alternate each year between corn and soybeans.
But now some are planting corn every year to meet the growing
demand for corn ethanol. Fargione says that’s prompting farmers in
Brazil to clear more land for soybeans.

“We can’t ask the world’s farmers to feed six billion people and then
say ‘also produce energy,’ without them requiring more land. That
land has to come from somewhere.”

But we don’t have to eliminate biofuels from the scene altogether.

Fargione says waste products from agriculture and forestry can be
turned into fuel. They don’t contribute to global warming. And
farmers could plant perennial grasses like switchgrass, where they
don’t have to plow the field every year.

“We can take land that’s been degraded, plant it to perennials, there’s
carbon storage in the soil, and then we can harvest those perennials,
and use those for biomass, and that could have a real benefit.”

He says we need policies that will make it profitable for farmers to
grow these better biofuel stocks.

Nathaniel Greene is a policy analyst at the Natural Resources
Defense Council. He says the research shows the need to develop
biofuels that really can address climate change.

“We can do biofuels smart, or we can do them stupid, and we have to
really choose.”

Congress has noticed. The new federal energy bill actually does start
encouraging these better biofuels.

The law tells the Environmental Protection Agency to figure out the
real global warming impact of the different biofuels.

Farmers Work to Conserve Water

Some experts say water will be the “oil” of the next generation. As it become
more scarce, prices are going to go up. For farmers, that’s serious business.

Some experts say water will be the “oil” of the next generation. As it become
more scarce, prices are going to go up. For farmers, that’s serious business.
Kyle Norris recently spent time with several farmers who say they think
about water constantly:


Anne Elder and Paul Bantle are farmers, and they’re pretty hard-core about
water. They keep a hollowed-out rock — it’s like a natural bowl — next to
the barn, and every morning they fill it with fresh water for the farm’s
smaller animals:


“And this amazing thing the cat comes and drinks, the chipmunks come and
drink, the birds come and drink and the bees all drink from the same stone.”


These folks consider water to be a valuable resource. They use it to grow a
variety of fruits and vegetables on their eleven and a half acres. The farm is
a biodynamic farm. Which means it’s organic, but it kind of goes a few steps
further. Anne Elder says biodynamic farming emphasizes healthy soil, and
how to make soil benefit the most from water:


“Healthy soil means it’s alive, it’s active, it’s not compressed but fluffy. It
will have a lot organic matter which will make it more sponge-like rather
than compacted hard tight soil. So when it does rain or when moisture does come,
fluffy soil can take that in and it can just drain through and the roots can
absorb it.”


They till an organic compost into the soil. It’s made of manure, vegetable
matter, hay, and straw. And as biodynamic farmers, they spread herbal teas
on their fields. They do this to feed the plants, and to fight-off problems like
fungus. Their farm is in southeastern Michigan and they get plenty of rain
storms. Paul Bantle says they try to take as much advantage from the rain as
possible:


“Rainwater is way better than any kind of water you’re going to pull from
earth. Irrigation water is cold when it comes from 65 feet down, it’s cold.
Whereas rainwater is warm, in the summer, obviously. And in the late spring
and early fall.”


The thing about cold water is that it shocks plants that have been sitting in
the warm sun all day. And that’s no good. When they need to water the
fields, they pump water from a 65-foot well.


Bantle says he thinks long and hard before using this water for irrigation. He
doesn’t want to dig down further to tap deeper aquifers, even if that means
that the crops will go through a hard time:


“It’s an issue. I mean it’s a huge problem. So definitely I try to be very
conservative about pulling water for irrigation.”


Basically, there are two main irrigation techniques typically used in farming. The first is
drip or trickle irrigation, and this is what Bantle and Elder use. It’s a slow,
easy method that takes time for the water to soak deep into the soil. It’s kind
of like a light, slow rain.


The other technique is overhead irrigation. Picture your garden hose on
spray, with overhead irrigation the water sprays all over. The downside is
that it wastes water because it evaporates and runs-off from the fields.


Lyndon Kelley is an irrigation educator with Michigan State University and
Perdue Extensions. He says drip irrigation is like a mini-van and overhead
irrigation is like a school bus:


“It’s sort of like are you going to take three or four kids to the baseball game
after school each day, well then you’re going to take the mini-van. But if
you’re going to take fifty kids to the baseball game after school every day
then you’re going to want a school bus.”


So, drip is typically used on smaller operations and overhead is usually
used on the larger ones. But Kelley says drip irrigation can be used on larger
farms. It depends on how the roots of the plant take-in water. Grape
vineyards, tomato plants, and some other vegetables respond well to drip
irrigation.


The farm that Anne Elder and Paul Bantle run is a relatively small operation.
They pay a lot of attention to their crops and they water them accordingly,
and all that effort takes a thought and labor:


“It’s almost like a holding-back mentality. How can I let these plants do
what they need to do, until which time the rains will come.”


Farmers are going to have to reevaluate the ways in which they use
water. Some scientists believe climate change will make some places much
drier, and a growing population is already putting heavier demands on the
existing water sources.

Great Lakes Record Lows

  • Lower water levels on the Great Lakes make some channels such as the Muskegon River too shallow for big freighters to enter fully loaded. (Photo by Lester Graham)

The Great Lakes are hitting new record low water levels. The water is so low that
big 1000-foot cargo ships are running aground. There’s debate about
whether this is just part of the historic ups and downs of the Great Lakes, or if it’s the
effects of global warming. Lester Graham reports from Lake Michigan’s Muskegon

The Great Lakes are hitting new record low water levels. The water is so low that
big 1000-foot cargo ships are running aground. There’s debate about
whether this is just part of the historic ups and downs of the Great Lakes, or if it’s the
effects of global warming. Lester Graham reports from Lake Michigan’s Muskegon
River, a trouble spot for some of the big ships:


Here at the end of the pier next to the lighthouse, it’s cold, it’s icy and it’s windy. And
it’s hard to imagine a ship navigating its way into this channel, but ships do on a
regular basis to bring coal to a power plant. This year, however, some of the ships
have ended up aground here simply because of lower lake levels and more sediment
in the channel:


“There’s been three this summer here in Muskegon. They go hard up on the sand.”


Dennis Donahue is the marine superintendent for the National Oceanic and
Atmospheric Administration’s Lake Michigan field station at Muskegon, Michigan. He
says this year’s groundings of cargo ships just hasn’t happened that often in the
past:


“Well, we haven’t had a grounding here, certainly in the last 15 years due to water
levels.”


Lester Graham: “So what’s happening here? What’s going on?”


Donahue: “Well, there’s a couple of things, we’ve got the water levels dropping and
then we’ve got some weather patterns that are carrying sediment to the mouth of the
Muskegon River. So, those two compound and create shoal areas.”


So lower water and a rising bottom mean channels are more shallow. That means
ships have to carry less cargo, and that costs the shippers reportedly a million
dollars per ship per year.


Scientists have been monitoring the dropping lake levels for close to a decade now.
At NOAA’s Great Lakes Environmental Research Lab, Deputy Director Cynthia
Sellinger says she’s been seeing a trend in the weather that’s causing the problem:


“We’re having a lot less precipitation and a lot more evaporation. And that’s
impacting the water levels on the lake.”


Less snow pack and rain mean less water filling the lakes, and with warmer winters
Sellinger says there’s less ice cover to protect the lakes from massive evaporation.
Historically, about 50% of the lakes’ surfaces have been covered by ice. These
days, it’s more like ten to 20%. Cold air hits the warmer water and
carries it away. For Lake Superior alone, a one-inch drop is more than 500 billion
gallons. During the past decade, Superior has lost nearly 13 trillion gallons.


“The upper lakes, Superior, Michigan and Huron, are very close to their record low.
So, it’s approaching an extreme. Superior reached its record low in 1926 and just
this year it broke the record low for September. So, 2007 now is a new record low
for Lake Superior. Lakes Michigan and Huron are approaching their record low.”


Sellinger and her colleagues are not ready to say global warming is causing the
lower lake levels. It might just be a part of a long cycle of ups and downs of the lakes.
But the lower water levels do fit some of the computer model predictions about
global warming.


Lower lake levels causing problems for big cargo ships and marinas catering to
recreational boaters are problems enough. But, some environmentalists say if lower
water levels are caused by global warming, the pressures on the water in the Great
Lakes likely are going to get a lot worse. Andy Buchsbaum heads up the National
Wildlife Federation’s Great Lakes office:


“The hidden threat of global warming is that not only does it affect Great Lakes water
levels simply because of increased evaporation or increased temperatures changes
precipitation, but the threat it makes to Great Lakes water levels is even greater.
Because global warming, global climate change, is having massive effects already
and is likely to have even greater effects on water supplies in the Southwest, the
Southeast and all over the country. And as those pressures increase, the pressure
to divert Great Lakes water will increase exponentially.”


We don’t know whether new diversions to dry areas of the country could cause as
much of a problem as less precipitation and more evaporation of the Great Lakes
already do. But, it would certainly aggravate the problem. The effects of water
levels dropping further mean more economic hardship for shipping and tourism. And
environmentalists say ecological damage to coastal habitat that fish and other
wildlife need to survive could be on a scale that’s not been seen on the Great Lakes
in recorded history.

The League of Conservation Voters released its Voter Guide to show how
the candidates stack up. They consider the candidates’ voting records
and their plans to tackle the big issues. Everything from Superfund
clean-up to energy. But especially global warming:


David Sandretti is with the League. He says all of the Democratic
candidates have aggressive plans for controlling greenhouse gasses. He
says Senator John McCain comes out way ahead among the Republican
candidates:


“He has a plan, he has supported a plan, he’s been working on this for
years. And his Republican rivals just simply don’t have that kind of
record.”


Sandretti admits candidates without a federal or state voting record
are hard to compare to candidates with a long Congressional record.
But his group considers their records as mayors or governors.

Cities Brace for Global Warming – Part 2

  • Cities can expand mass transit, getting more cars off the road and giving people more options to help reduce emissions that contribute to global warming. (Photo by Karen Kelly)

Census figures show that more and more North Americans are now living in cities. For those who want to fight climate change, that means changing the way these urban folks live. In the second of a two-part series on climate change, Karen Kelly has the story of one city councilor who’s made that his mission:


“We’re at Bronson and Fifth. It’s a four lane roadway into Ottawa.”


Clive Doucet is a city councilor in Ottawa, Canada’s capital. He’s standing about half a block from where he lives:


“This kind of street is a community killer, it’s a planet killer. It’s the fruit of 5,560 years of building cities for cars and not human beings.”


Doucet loves cities, which is why it pains him to see a once-beautiful neighborhood street become, as he calls it, a traffic sewer. It’s loud, it’s polluted, and it’s not safe. Three pedestrians have been killed near this corner in the past five years, and there’ve been many accidents.


Doucet was an activist for a long time, but after running for city council he realized the city has the power to change the climate. It builds the roads and it controls the public transportation:


“Public transit has, every environmentalist knows is one of the main keys to solving the environmental crisis. I mean, 45 to 50 percent of greenhouse gases come out of our use of land and the tailpipes of cars and trucks. We can get rid of most of that and we can not change our lifestyle one bit; in fact, we can make it better.”


Doucet hops on his bike to show what he means. He winds through the traffic and then stops along Ottawa’s five-mile-long light rail track:


“This runs parallel to the road we were just on. It’s a test line. It carries a hundred and 50 passengers every 15 minutes and when we get the two lines up and running, it will carry three times the traffic or more as Bronson and it’s quiet. We’re standing at the station now. You’re like in a church. See the train’s coming. Do you hear any noise? It’s beautiful, isn’t it?”


Doucet’s vision for his city is a comprehensive light rail system. He says it will reduce air and noise pollution, and make the city friendlier for pedestrians and cyclists, but Doucet is thinking about the bigger picture, too. And there, he’s not optimistic. He’s noticed that the winters in Ottawa are warmer now, and that’s disturbing for people because they really embrace winter.


Almost every park has an outdoor hockey rink, and people ice skate, not just for pleasure, but to get around. Doucet says he’s afraid that climate change will destroy what makes his city special:


“It’s incredibly sad. I mean, I’ve skated to work all my life and I live about a block from the canal I take my skates down and I’d skate to work and skate home. And I’ve seen countless marvelous sunrises on the canal. It is difficult to imagine my life without that. Those experiences have given my life poetry.”


Doucet says he’s pretty much given up hope on the federal government. He says they’re too beholden to big industry to really curb the emissions that cause climate change.
But at the local level? He says a lot can be done.


He recently wrote a book, Urban Meltdown: Cities, Climate Change and Politics as Usual. In it, he says it’s time for city residents to get tough:


“Go after your municipal politicians and say, you know something, we want to have a city that’s pedestrian-based, that’s public transit-based and we want you to stop building roads. You can do stuff about your local government and the way you live locally.”


Doucet wouldn’t say it’s easy. Last year, Ottawa signed a contract to expand its light rail system. Then, a new mayor came in and the plan was scrapped. Doucet thinks it will happen eventually, but in the meantime, he’s still fighting the rush hour traffic on his bicycle.

Public health officials are stepping up their concerns about global warming.
Chuck Quirmbach reports:


Some predictions about rising global temperatures look at the potential threat to the environment
and wildlife, but the American Public Health Association says with more scientific evidence of
climate change, it’s time for local health departments to talk to people about the potential threat to
humans.


Environmental Studies Professor Jonathan Patz was a key author of a recent UN paper on
climate change. He says higher temperatures could lead to more heat waves, smog and
infectious diseases:


“…Carried by insects or water-borne diseases, if we’re talking about not only warming
but extremes of the water cycle and potential for contaminating our drinking water systems.”


The Public Health Association will take about six months to develop recommendations
for dealing with the human health impacts of climate change.

Lower Lake Levels: Multi-Causes

There’s more concern about lower water levels in the Great Lakes, both due to increased drainage, and possibly global climate change. Chuck Quirmbach reports:

Transcript

There’s more concern about lower water levels in the Great Lakes, both due to increased drainage, and possibly global climate change. Chuck Quirmbach reports:


More data from a privately-funded study show long ago dredging on the Saint Clair River near Detroit may be one of the reasons for low water levels in Lakes Huron and Michigan.


Another study by the US-Canada International Joint Commission is looking at what to do about the higher flows out of the lakes. But hydrologist Roger Gauthier, of the Great Lakes Commission, adds a long warming trend to the list of factors affecting levels in Lakes Huron, Michigan and Superior:


“We’ve had below average snowfall. We’ve had very little ice cover in terms of thickness or duration. Much warmer lake temperatures.”


Less ice cover leads to more wintertime evaporation. Experts say trying to fix the drainage problem and control global warming should be goals.

Transcript

Scientific data indicate lower Great Lakes water levels might be because of global
warming. But, Lester Graham reports many people believe the lower levels are
because of water withdrawals:


The National Oceanic and Atmospheric Administration’s Great Lakes Environmental
Research Lab has been investigating the lower water levels on the Great Lakes for
several years now. They’ve recorded less snow pack to replenish the lakes, and
less ice cover to prevent evaporation during the winter. That’s corresponded with the
lower lake levels.


The inference is climate change – or global warming – is causing the Great Lakes to
lose water. But many residents in the Great Lakes region are convinced the water is
being piped away, either by industry or diverted to Western states.


Most of the water diversions in the Lakes have been around for a century and are
well-monitored. But, some politicians play on fears that the lower lake levels are part
of a grand conspiracy to steal Great Lakes water for more politically powerful states
in drier regions.

PB &Amp; J SAVES THE WORLD

global warming. Jennifer Szweda Jordan recently visited the founder of the
PB and J Campaign:

Transcript

What could be more American, more humble, than a peanut butter and jelly
sandwich? And yet one activist suggests a PB and J a day could help slow
global warming. Jennifer Szweda Jordan recently visited the founder of the
PB and J Campaign:


(Brown:) “So we just spread some peanut butter on your banana bread.
Would you like to try it?”


(Jordan:) “Yeah. Yeah.”


Bernard Brown is trying to get people to see the peanut butter and jelly
sandwich in a new light. On his website, there’s a saintly glow behind a
graphic of the sandwich. He thinks eating a peanut butter and jelly sandwich
could just save the planet.


Brown estimates that eating one peanut butter and jelly sandwich for lunch
versus, say, a ham sandwich, or a burger, saves nearly three and a half
pounds of greenhouse gas emissions and 280 gallons of water. In Brown’s
kitchen, he waves a peanut butter covered knife. He explains why he’s using
this comfort food to change the world:


(Jordan:) “Why peanut butter and jelly? Like it’s a pretty processed, highly
processed kind of…”


(Brown:) “Yeah, it’s because it’s the most familiar food I could think of that
didn’t have, that was sort of purely plant-based and wasn’t animal-based at
all. It’s one of these things like people might be scared by words like vegan
or vegetarian. But there’s absolutely nothing alternative about peanut butter
and jelly.”


What’s more, some experts suggest Brown’s not, well, nuts. A Princeton
bioethicist says if 100 million Americans – that’s one of three of us – traded a
burger for a peanut butter and jelly sandwich, it would make an impact on
the environment. And if we made the same choice three times a week, it
would make a huge impact.


Those who worry that Brown’s dietary suggestions might make a huge impact on the
waistline, take heart. A serving of two tablespoons of peanut butter does have nearly 200
calories and 16 grams of fat. But the fat is not the worrisome saturated type and there’s
some evidence that eating a small amount of nuts each day might reduce the risk of heart
disease, and even prevent cancer.


Of course, Brown and nutritionists still suggest partnering a low-sugar peanut butter with
whole grain breads, and low-sugar jellies, or even fresh fruit. And Brown hopes people
consider moving beyond the peanut butter and jelly:


“On the website, we go into other different, other foods people could try – a
bean burrito’s a good example. Black bean soup. Falafel. We even tried
mentioning tofu. I’m not sure if it scares people away.”


Brown really wants to win over people by keeping the campaign from
becoming a crusade. He says that even a vegetarian like him is turned off by
overly radical, moralistic or bloody efforts against meat-eating, or for saving
the world:


“I think have a lot of messages that, ‘Things are very scary, you must change
your life.’ And so, it’s to try to come in with a softer approach, I think. The
ideal is to reach people who aren’t reached with more intense messages.”


Brown hopes to disarm you with playfulness. And what could be more playful than
playing with your food – turning peanut butter and jelly sandwiches into
people?


(Sound of fast typing)


On a laptop computer, Brown calls up a slide show he’s made of a
gingerbread-style cutout couple, peanut butter and jelly boy and girl. They’re
making a snowman and chatting. When PBJ boy gets a little sad, his
companion wonders why:


“He’s concerned that maybe global warming will mean there won’t be
conditions for making snowmen in the future.”


(Jordan:) “Can you read this one? They’re very sophisticated?”


(Brown:) “PBJ Girl says, ‘Well, anthropogenic climate change is a serious
problem. It should only affect the climate gradually. I’m positive we’ll able
to build a snowman next year.’ And then PBJ boy says, ‘Well, I guess that
makes me feel better, but what if our grandkids never see snow?'”


The girl says if we reduce greenhouse gas emissions, it might stay snowy in
the winter. Then she backs up Brown’s claim that it’s easy enough to do: just
have a sandwich that looks a lot like her and visit the pbjcampaign.org
website.


PBJ boy and girl are just the beginning.


(Sound of jingling cookie cutters)


Brown has a jar full of more cookie cutters like those he used to make the
boy and girl. He figures a wider variety of peanut butter and jelly creatures
could act in slide shows and carry out other environmental messages.


Brown’s not just limiting his work to online skits. He’s also trying to build a
calculator into his site so visitors can register the number of peanut butter
and jelly sandwiches they’ve eaten. Then he can track the impact. No
matter what, though, Brown plans for the campaign to remain light, fun, and
easy to swallow.
