A new report in the journal Nature Reviews
Cancer looks at cancer in wildlife. Mark
Brush reports, the disease in animals is
sometimes caused by pollution:

The authors of this paper looked at a lot of research on cancer in wild animals. Some of these studies linked the cancer cases to pollution.

Beluga Whales along the Canadian Atlantic coast developed tumors after they came in contact with chemicals from aluminum smelters. And some fish and clam species have developed cancers after being exposed to pollution.

Denise McAloose is a veterinarian with the Wildlife Conservation Society. She’s the lead author of the paper.

“People should care about cancer in wildlife because, especially in those cancers that are driven by environmental factors, those environmental factors affect not only the animals, but people as well.”

For example, the people who worked in those aluminum smelters also had higher rates of cancer.

She says more research into the link between pollution and cancer in animals needs to be done. Because looking at how the disease affects wildlife might help us treat or prevent cancer in people.

Television dolphins like Flipper
and the performing dolphins at
Sea World can trick people into
thinking it’s okay to feed and
swim with wild dolphins. But
Rebecca Williams reports dolphin
researchers say our behavior can
hurt and even kill dolphins:

(sound of a shorebird crying out)

Fort Myers beach is packed with tourists. I meet a guy named Justin who’s here in Florida from Cleveland. He’s already gotten close to wild dolphins.

“We were out here swimming and dolphins got within a foot of us. It was amazing. I’ve never seen that.”

In this case, he wasn’t doing anything wrong – because the dolphins came up to him. But swimming with wild dolphins can actually be considered harassment if you approach them or touch them.

That’s bad for the dolphins because it can change their behavior. It can disturb their feeding and resting behavior. And it can separate dolphins from their babies.

So it’s illegal to swim with or harass dolphins. You can get fined and even end up with some jail time. And that’s just the beginning of the dolphins’ problems.

Dolphin encounters are getting more common in Florida and Hawaii and a lot of other places. There’ve been more tourists and more boaters in the water… and more commercial operations that promise you’ll get a chance to feed or swim with dolphins.

As cool as it might be for us, it’s actually terrible for dolphins. When people feed them they can get addicted to human handouts.

Cartoon Dolphin PSA: “For me it started with one hit of sardines, oh sardines… that’s where I learned to beg. It was easy to score free fish… with this dolphin smile? Yeah it’s illegal but no one cares…”

That’s a cartoon dolphin in rehab with a bear, a raccoon and a seagull. All those other animals we’ve gotten into some bad habits with.

It’s a message put out by the Mote Marine Laboratory in Sarasota.

(sound of dolphin playing in tank at the Marine Lab)

Randall Wells is the head of dolphin research at the lab. He’s spent almost four decades studying dolphins.

He says, in recent years, there’s been a dramatic increase in the number of dolphins getting into trouble with people. More people feeding them and getting too close to dolphins in their boats.

“And we’ve seen an increase in mortality from these kinds of interactions – from people luring animals in towards boats, in towards fishing gear. Dolphins have begun to take bait from lines getting tackle including hooks and lures in their bodies and killing them or seriously injuring them.”

He says, if you feed a dolphin, it’ll often start begging for food from people. And that dolphin will teach its babies or other dolphins to beg.

Sometimes they’ll even eat things that aren’t food. One dead dolphin had a plastic snake in its stomach.

If dolphins get closer to boats, they can get snared in fishing line. It can slice through their flippers. Once, Randall Wells rescued a dolphin that had a Speedo on its head. And because it couldn’t shake it off, the suit was cutting into the dolphin’s flesh.

Wells and his team have been doing a lot of outreach to stop people from getting too close to dolphins. And he says most of the time, it works.

“But there’s still a half percent of people that, by their own admission, insist on interacting with these animals – feeding them and approaching them in ways that are illegal, just because they can and they’ve never seen the negative consequences of doing that.”

If you want to go on one of those dolphin viewing tours, there are some ways to make sure the tour operator’s not adding to the problem.

Stacey Horstman helps run a program called Dolphin Smart. It certifies dolphin tours as responsible.

Right now there are only four businesses in Key West and one in Alabama that’ve gotten certified. But, she says, if you’re in a place without Dolphin Smart tours, you can still ask questions.

“Just to make sure that feeding is not being promoted in any way, that they’re promoting responsible viewing from a distance.”

That means staying at least 50 yards away from dolphins.

She says any ad that shows people swimming with dolphins or handing them fish is usually a sign of an irresponsible business. So those are ones to stay away from.

Dolphins might look cute and friendly, but Horstman says they are wild animals and they need their space.

Native Americans Lose Land to Climate Change

Over the next century, rising sea levels will change coastlines all over the world. But the impact might be most dramatic in South Louisiana. A study out last month predicts the state will lose up to 5000 square miles in the next century – a chunk of land the size of Connecticut. If the report’s authors are right, that means a lot of people in Louisiana are going to have to relocate – become climate refugees. Samara Freemark has the story of one of the first communities to be displaced:

It was sometime in the mid-1970s that Albert Naquin first realized that Isle de Jean Charles was sinking. Naquin had grown up on the island. He’s the chief of a group of Choctaws who have lived there since the 19th century – and when he was a kid, it was a pretty good community: it had stores, a couple of churches, horse pastures and fields. But those are all gone now.

“Salt water kept coming in, faster and faster, and now it’s basically just beach.”

Isle de Jean Charles is sinking into the Gulf of Mexico.

The list of reasons why is long. There’s subsidence- that’s the natural phenomenon where delta regions kind of settle down on themselves. There are the dams that block the sediment that used to wash down and build the land back up. There are oil company canals that slice through the wetlands, hurricanes that tear up the island’s coastline, and, of course, there’s rising sea levels.

All together they explain why Isle de Jean Charles used to be about 4 miles across and now has shrunk to a quarter mile.

“Now, we see the disaster that is Isle de Jean.”

We’re in Naquin’s pickup truck, and he’s driving me out to the island.

“See this little house moved across the way, this house. These 1, 2, 3 are deserted.”

Naquin himself moved off the island awhile ago. But for years he was happy to support families who chose to stay. In fact, when the US government came to him in 2002 and offered to pay to help people move off the island, he resisted.

“So, I said, ‘what they gonna do, tell us they’re gonna move us there and then next thing send us a bill for the house?’ You know, so I said, ‘no, that’s just a modern day Trail of Tears. We’re not moving.’”

But lately Naquin has just gotten tired. Tired of evacuating people before storms, tired of helping them rebuild after, tired of watching the sea nibble away at the island.

And so he decided – enough. For the past year he’s been on a mission to convince the 25 families still living on the island to abandon it.

“They’re not going to save the island. It’s going to be gone. Either we move now or we move later, ‘cause we will move.”

But not everyone is ready to leave.

(sound of greeting and talking)

Naquin pulls over to talk to Dominique Dardar.

Dardar’s house was leveled by Hurricane Gustav last summer. He’s rebuilding it with pieces of other houses he’s found blowing around the island- bits of roof and siding. Dardar says he’s not moving.

“I ain’t never gonna move. I’m gonna stay over here. That’s my territory.”

Across the street Wenselas Billiot lives in a house raised 13 feet in the air.

Billiot is Naquin’s brother in law. He’s in his 80s and has lived on the island his whole life. I ask him what he’ll do if the island shrinks any more.

“That’s going to be rough. But, as long as I can stay, I’ll stay. I was born and raised on the island. As long as I can stay here I’m going to stay.”

Albert Naquin hasn’t given up. He thinks if he can get everyone to agree, the government will help the tribe get a big piece of land where they can all relocate as a group. He’s already thinking of names for the new town.

“We could say, Island Number Two, or Isle de Jean Charles New Beginning, or something like that. But I think we just name it Isle de Jean Charles 2. I think that has a good sound to it.”

In short, Naquin is trying to figure out how to keep the idea of Isle de Jean Charles alive, even when the island itself no longer exists.

It’s a challenge many Louisiana communities could soon face.

Food, Inc. Exposes Industry’s Secrets

A new film documentary that’s hitting theaters now looks at the underbelly of the food industry. We’ve all heard about food recalls because of E.coli bacteria contamination. There was peanut butter, hamburger, spinach – and the list goes on. Lester Graham reports the documentary, Food Inc., looks at why food gets contaminated and reveals a lot more about our industrial approach to producing food:

This documentary is disturbing. It shows some of the things that happen to our food behind the scenes.

“There is this deliberate veil, this curtain, that’s dropped between us and where are food is coming from. The industry doesn’t want you to know the truth about what you’re eating, because if you knew, you might not want to eat it.”

The film, Food Inc., looks at how raising animals and growing crops have been industrialized from the farm to the grocery store.

Food processors have relied more and more on technological and chemical fixes to food contamination problems and storage issues instead of questioning whether the assembly line factory, mass production approach is the best way of handling food.

It looks at how companies such as Monsanto are treating farmers who want to save their seeds to replant next year – hint — involves lawyers and lawsuits.

It looks at how companies fight against labeling that would give consumers more information on packages. They say more information might unnecessarily scare their customers.

And it uses video from hidden cameras to show how animals are treated at big factory slaughterhouses.

Robert Kenner is the film’s producer/director. He thinks most people won’t like what they see.

But, he also says things can change. If people think about it, they actually vote with their forks three times a day.

“On some level, I think it’s going to be lead by moms who don’t want their children to be eating this food that’s making them sick.”

Kenner says these massive food recalls we’ve seen over the last several years are bad enough, but there’s a greater threat to our health.

“Obviously E.coli and things like that are very frightening, but ultimately it’s the everyday stuff that we don’t see – such as the sugar, salt and fat – that are making us fat. And that’s what I think needs to be changed most. That we get food that’s healthy and that we don’t subsidize food that’s making us sick.”

Food Inc. interviews farmers and food processors and some food industry critics, including author Michael Pollan.

He says those foods subsidized by the government are the kinds of ingredients that are causing some of the leading health problems, such as early onset of diabetes and heart disease.

“All those snackfood calories are the ones that come from the commodity crops – from the wheat, from the corn, and from the soybeans. By making those calories really cheap, that’s one of the reasons the biggest predictor of obesity is income level.”

Pollan says it’s wrong when it’s cheaper to buy a cheeseburger than it is to buy broccoli.

The director and producer of Food Inc., Robert Kenner says he knows the film spends a lot of time looking at the dark side.

But he also gives some of the progressive food processors and even Wal Mart credit. He says they’re doing something about meeting the consumer demand for better, safer and more healthy foods.

“There are lots of great options out there and they are growing options.”

Such as farmers markets, grocery stores letting you know if food is grown locally, and a growing selection of organic foods.

Kenner says he hopes his film, Food Inc., not only outlines the problems with how our food is handled, but gets people to start asking questions about the choices they make when it’s time to eat.

Keeping Panthers and People From Colliding

People are killing Florida panthers.
Usually it’s not intentional. But
Rebecca Williams reports biologists
are trying to figure out how to keep
panthers and people from running into
each other:

There are only about 100 Florida panthers left in the wild. They’re endangered.

If you live down here, it’s one thing to know there are panthers hunting for food in the Everglades. But it’s something else when they visit your backyard.

(sound of tropical birds singing)

Rebecca Galligan and her husband didn’t give panthers all that much thought. Until one day, when they came home from work, and found their dog Riley had been killed.

“The scratches on the body and the way he’d been killed it was pretty obvious it was some sort of wild cat.”

Two days earlier something had killed their neighbor’s sheep. Then a dozen goats got killed.

A biologist decided the predator was a panther. In the past few years in South Florida, more people have been losing pets and farm animals to hungry panthers.

Galligan calling to dog: “C’mere, have a seat!” (Roscoe sniffs the microphone)

Now, when she’s away, Rebecca Galligan keeps her dogs Roscoe and Sable in a little panther-proof house. It’s made out of steel and chain link fencing.

“There’s so much nature and wildlife, and so I mean, we just can’t destroy it all because we want to be safe. That’s why we had this pen built, so we can keep the animals a little safer from the animals that live around us.”

And a lot of people here think the panthers have a right to stick around.

But some say there’s a gaping hole in the law that’s supposed to protect panthers.

The panther has never had what’s called critical habitat set aside. That means developers don’t have to consider the land panthers need to survive. Panther habitat or not, they can just build.

So panthers are getting crowded out by subdivisions and huge new cities.

Andrew McElwaine is president of the Conservancy of Southwest Florida. He’s asked the Obama Administration to officially give panthers that habitat.

“So, the more habitat we take away, we’re forcing panthers to move out. We’re getting reports of panthers in urban areas of Southwest Florida looking for somewhere to live, if you will.”

And, as people move in, panthers are becoming roadkill.

Last year 10 panthers were killed by cars. So far, this year, six more panthers have been killed.

(sound of cars whizzing by)

“There are some panther tracks here. There’s one there… and there…”

Mark Lotz is a panther biologist. We’re hanging out in an underpass below the highway. It was built for panthers. Miles of fences run along the highway and make a funnel, so panthers have to go below the road.

Lotz says there are 36 panther underpasses on this stretch of highway. And he says fewer panthers get hit here. But underpasses are expensive – about $2 million each. And giving panthers room to live isn’t always even that simple.

Lotz says the biggest challenge is getting people to adapt to panthers. To him, the cats are majestic. But he also knows a lot of people think they’re terrifying. Somebody actually shot a panther a few months ago.

“Naysayers could make the argument there’s no panthers in Pennsylvania or any other eastern state and things are going just fine. But then I would counter – look what’s happening with deer populations there. You know, panthers are part of the ecosystem. Without them there’s just something missing. In a way part of the wildness disappears.”

But if panthers keep running out of space, they could disappear.

We talked to the Secretary of the Interior, Ken Salazar. And we asked him whether he’d set aside critical habitat for panthers.

“Yeah, we’ll have to get back to you on that.”

That’s been the kind of response he’s given to other reporters too.

Giving panthers habitat protection would mean more obstacles for developers. And, in this economy, that could be pretty unpopular.

Keeping Chemicals a Secret

  • Drilling for natural gas includes pumping water and chemicals at high pressure into the ground to force out pockets of gas (Photo courtesy of Argonne National Laboratories)

The federal law that protects drinking water allows companies drilling for natural gas to inject chemicals into the ground. The exemption for gas drilling operations also allows the companies to keep the chemicals they use a secret. Conrad Wilson reports environmentalists want the exemption removed:

The federal law that protects drinking water allows companies drilling for natural gas to inject chemicals into the ground. The exemption for gas drilling operations also allows the companies to keep the chemicals they use a secret. Conrad Wilson reports environmentalists want the exemption removed:

For decades, drilling for natural gas includes pumping water and chemicals at high pressure into the ground to force out pockets of gas.

Environmental groups believe the chemicals are contaminating wells and aquifers here in the western U.S. Now gas drilling is moving east to places closer to cities such as Philadelphia and New York.

Several Democratic Members of Congress have introduced legislation to repeal the exemption in the Safe Drinking Water Act.

Randy Udall is a co-founder of the Association for the Study of Peak Oil-USA, an environmental group. He says as more gas is found, people in the East can expect more drilling.

“For better or worse, whether you like it or not, as time goes on, were going to be drilling in places where people are living.”

The oil and natural gas industry says the chemicals they force into the ground are “trade secrets.” They say the process is safe.

Sea Levels Threaten Coastal Towns (Part One)

It’s beach weather – and along the mid-Atlantic one of the most popular beaches is Ocean
City, Maryland. For years, engineers have been battling back the ocean to save the beach
and the town. And as Tamara Keith reports, that fight is only going to get tougher and
more expensive if predictions of sea level rise from climate change become a reality:

It’s beach weather – and along the mid-Atlantic one of the most popular beaches is Ocean
City, Maryland. For years, engineers have been battling back the ocean to save the beach
and the town. And as Tamara Keith reports, that fight is only going to get tougher and
more expensive if predictions of sea level rise from climate change become a reality:

When the sea level rises, Ocean City feels it. It’s on the front lines – a barrier island on
the edge of the Atlantic.

(sounds of water)

Terry McGean is the city engineer for a town he describes as a working class resort.

“Our industry is tourism, and the real reason people come here is the beach.”

But in the 1980s, that beach was reduced to a narrow strip. Not so today, all thanks to a
massive, and expensive, beach replenishment project. In 1991 countless tons of sand
were brought in, dunes were built. But that wasn’t the end of it.

To keep up with erosion, McGean says the beach here at Ocean City has already been re-
nourished 4 times.

“Approximately every 4 years we’re doing a re-nourishment project. To give you an idea
of the scale, that’s 100,000 truck loads of material that we’ll put on here. Though it
doesn’t actually come on a truck? No. It’s pumped in a dredge from out in the ocean.”

It is a constant fight, because the waves keep coming, keep pulling the sand back out to
sea. Scientists say this is partially just normal erosion. But some of it at least can be
blamed on global climate change and sea level rise. Over time, they say, the share of the
problem caused by climate change will grow.

“If you hadn’t done the beach replenishment do you have any sense of what this would
look like right now. There probably would have been no public beach left in many of
these areas.”

So far fending off the sea has cost $90-million, split amongst local, state and federal tax
dollars. But engineers estimate some $240-million in storm damage has been prevented.

“Holding back the sea is an economic proposition. If you’re willing to spend the money,
the sand exists to elevate any given barrier island.”

Jim Titus is the project manager for sea level rise at the Environmental Protection
Agency. And he’s been sounding the alarm about climate change for years. And he says
policy makers and the public will eventually have to decide which beaches, which
communities are worth saving.

“The challenge for communities like Ocean City is to persuade everyone else that they
are one of those cities that are too important to give up. And then to get their residents to
cooperate in doing what it takes to do to gradually elevate the entire community with a
rising sea.”

But if you think in geologic time, like University of Maryland professor Michael Kearney
does, there isn’t a whole lot of hope for barrier islands like Ocean City.

“It’s essentially a pile of sand. There’s really nothing permanent about it.”

Kearney studies coastal processes.

“The long term prospect of any barrier surviving the projected rates of sea level rise, even
at the moderate rates – the so-called moderate rates, that the IPCC predicted is pretty
slim.”

Ocean City engineer Terry McGean just isn’t buying it. He thinks Ocean City can survive
sea level rise.

“I think that we can design towards it and we can probably build towards it and with
responsible actions we can live with it.”

As long as there’s enough sand and money to keep it going.

Sea Levels Threaten Coastal Towns (Part Two)

Scientists are pretty certain climate change is going to cause the sea level to rise. It’s
happening already, actually. In communities around the Chesapeake Bay, people are
getting a sneak preview. Tamara Keith reports some people there are trying to work with
nature rather than resist it:

(sound of kids planting)

It’s been raining in Woodland Beach. The community is just off of the Chesapeake Bay
in Maryland. The ground here is so soft you sink into it. Mud is everywhere. And that’s
just fine with the volunteers planting native grasses on a sloping hillside.

Stephen Hult is trying to keep things in order.

“And when we plant them we want them all the way down. I’m telling everyone twice.”

Hult heads up shoreline restoration projects for the local property owners association.
And there’s a lot of shoreline to restore.

“The shoreline, in parts of the community since the 1930s, have eroded 20 feet. Year to
year, one barely notices, but if you look at aerial maps of what it used to be like
compared to what it is, it really is quite dramatic.”

There’s been tons of erosion here. The land all along the mid-Atlantic coast is also
slowly sinking. Combine that with global sea level rise and you get erosion in overdrive.

Hult says the community is trying to restore the beach with rock and dirt and sand and
grasses to hold it all together. This is what’s called a living shoreline.

“We have now, with this project it will be well over half a mile of living shorelines that
we’ve installed.”

It’s a relatively new concept, a more natural approach to the gnawing problem of
shoreline erosion. Living shorelines create buffer between the water and homes. They are
kinda like the tidal wetlands that used to be here – before property owners started building
sea walls, also called bulkheads.

Jana Davis is associate director of the Chesapeake Bay Trust. It’s one of the organizations
funding this shoreline restoration. And Davis also happens to live here.

“It’s a wonderful alternative that provides just as good shoreline protection while also
providing a lot of really important habitat benefits that a bulkhead or rock sea wall does
not provide.”

Good for wildlife, and she says, it’s adaptive in the face of sea level rise.

“If sea level were to rise another foot, for example. The marsh could kind of migrate
inland, whereas if you had a bulkhead obviously there’s no migration because it can’t
move.”

But most of the people with bulkheads are NOT buying it. They want to protect their
property from the sinking land and rising water, and a lot of them don’t think a bunch of
rocks and grass are going to cut it.

Kevin Smith is chief of restoration services for the Maryland Department of Natural
Resources.

“There’s many places you can go and look at miles of shoreline and not see any natural
shoreline at all. It’s all armored off.”

Smith met me at a nature center along the bay. A few years ago, a stretch of bulkhead
here was replaced with a living shoreline. The natural ebb and flow of these shorelines
has made some property owners skeptical. They want the shoreline to stay put.

“If these types of projects don’t protect that shoreline from erosion, then homeowners are
not going to want to do it.”

But Smith insists these projects do work, and long term they’re going to be more
sustainable and more flexible than bulkheads – which over time will lose the battle
against the constant pounding of the rising sea.

Predicting Wildfires in a Warmer World

Climate change has already brought
warmer temperatures, rising sea
levels and melting glaciers. Now,
researchers believe global warming
will cause major shifts in wildfire
patterns around the world. As Sadie
Babits reports, scientists hope to
predict where future wildfires will
light up:

Trying to predict where wildfires are likely to start decades from now, is
kind of like getting a full body scan.

(sound of medical scanner)

Except instead of a medical scanner, scientists scanned the earth using
satellite data, climate models and the history of present day wildfires to
map out global wildfire patterns.

“The impacts of climate change on wildfires are expected to be widespread
around the world.”

Katherine Hayhoe is a climate scientist at Texas Tech University. She’s part
of a group of scientists that has for the first time, tried to project where fire
hotspots will crop up around the world. She says they found that climate
change will affect wildfire patterns.

Hotter temperatures and rain and snow coming at different times in the
year or perhaps not at all, will mean forests and grasslands will dry out
quicker – becoming tinder boxes for fire.

In the next 30 years, scientists believe that the Western U.S. will continue
to see catastrophic fires like the recent blaze in Santa Barbara, which
destroyed 80 homes.

In the next 60 years, they predict wildfires will increase in the Corn Belt and
spread into the East Coast.

Hayhoe says having an idea of how wildfire patterns will shift will help
communities better prepare.

“We can never eliminate the risk of climate change entirely but by making
wise choices and planning strategically we can minimize those risks.”

Some communities are already taking steps to prevent wildfire. The city of
Bend, Oregon was one of the first in the country to launch a public
education campaign to get homeowners to fire proof their homes. The
program, called FireFree, started more than a decade ago, after a massive
wildfire burned nineteen homes and scorched thousands of acres.

“It was something that scarred our community.”

Gary Marshall is the deputy chief of Bend’s Fire Department.

“We have this history of people wanting to live outside the urban area and
live out in rural areas, where they can see the deer and be out in the trees
and live that lifestyle that most Americans who move out to the West want
to be a part of that.”

Bend lies in what’s known as wildfire alley. Every year there are dozens of
fires that crop up either from lightning strikes or from people. The flames
are fed by dried out grasses and forests so dense you can’t see through
them. Add homes to the mix and you have a recipe for disaster not just
here but throughout the West.

But Marshall says the Fire Free program is working.

(sound of a truck driving on a dirt road)

County forester Joe Stutler and Gary Marshall drive me through
neighborhoods outside Bend. We stop first at an upscale suburb called
Coldera Springs. Everyone here has volunteered to fire proof their new
homes.

But just down the road, there’s a much older suburb and a lot of trees that
have been thinned out.

Sadie: “You can’t see through the trees it’s so dense.”

Joe: “You can’t walk through.”

Gary: “And a firefighter won’t go in there. You’d write that off. So if you
don’t take care of it, the fire will.”

That’s a picture that climate scientist Katherine Hayhoe hopes to avoid.
She says having a long term view of where wildfires might pop up could
help communities to start now and follow Bend’s lead.

It took Bend years to get most of the homeowners here to take
responsibility, and give their homes a fighting change to survive a
devastating blaze.

Out West, a lot of cities figure many more people will be moving in over the next few
decades. Water engineers wish those people would bring along all the water they’ll
need, but of course they won’t. Shawn Allee reports these cities want to pipe more
water from far away, and some people think that’s a bad idea:

The air in Colorado Springs is usually so dry it quickly chaps your lips.

What gives? Colorado Springs sounds wet enough.

“There’re really no springs in Colorado Springs, so when you start talking
about water, it’s a divergence between our name and reality. Sounds like we
had a lot, and in reality we didn’t.”

This is Matt Mayberry, Colorado Spring’s historian.

I’ve heard about this massive water pipeline project the town’s cooking up, and I was
curious just how long the city’s worked to quench its thirst.

Mayberry’s got an exhaustive book on that with an exhaustive title.

“Blah, blah, blah … the emergence and appropriation of rights in Colorado
Springs.”

The crib notes version?

Early on, buffalo manure poisoned Colorado Spring’s creek, so people dug wells.

Then, the wells got infested with grasshoppers.

And the town grew, and grew, and grew again.

“Very soon you had to bring water from further away, and ultimately to the
Western Slope which is a couple hours drive of here.”

Today, Colorado Springs pipes water through the Rocky Mountain range.

Doing the extraordinary for water is kinda ordinary for Colorado Springs.

Its latest pipeline project is called the Southern Delivery System, and it’ll pump nearly
80 million gallons into town each year – and it’ll pump that water forty five miles –
completely uphill.

Impressive, but some people are asking tough questions about it.

“Our concern with this project is the greenhouse gas emissions that it would
contribute to.”

Stacy Tellinghuisen is with Western Resource Advocates, a Colorado environmental
group.

She says there’s a connection between pumping water uphill and a large carbon
footprint.

“Water is heavy. Pumping it over a great distance takes a lot of energy, and
in the process it would require something along the lines of 60 MW of power,
which is about a tenth of a power plant.”

And, for the most part, the utility burns natural gas and coal to generate power. Both
emit carbon dioxide, a greenhouse gas.

Tellinghuisen says Western cities are considering at least five other water pipeline
projects, some with even larger carbon footprints.

She wants Colorado Springs to set an example by using dedicated low-carbon sources
like wind power for its water pumps.

I ask the Colorado Springs Utilities about that.

Keith Riley helped plan the Southern Delivery System.

“We think there are some ways we can minimize the carbon footprint by
looking at some new technologies.”

Riley says there were lots of environmental regulations to wade through before the
Southern Delivery System got approved.

But a large carbon footprint doesn’t disqualify utility projects.

Riley says, even if carbon were considered, the project might have gone forward
anyway because the city’s expected to grow over the next few decades.

“Water is the essential element for all of us, so when it comes to that level of
sustaining our own lives, then you get to some trade-offs on what we’re
willing to do to keep ourselves alive where we we live, where our cities are.
No matter what happens, we’ve got to move water to Colorado Springs, and
we’re uphill from the river, so we’ve got to get the water uphill one way or
another.”

Riley says Colorado Springs Utilities is considering low-carbon renewable power for its
new pipeline.

But it’ll be expensive, and no one’s stepped forward with all the money.

Other Western cities are engineering clever ways of moving loads of water around,
too. And it’ll be a political and financial challenge for them to pay for the carbon
footprint.
