Environmental groups have pushed for decades to get the federal government solidly behind solar energy. Shawn Allee reports some of them don’t like the government’s most recent effort to promote it:

The Federal Bureau of Land Management developed 24 “solar energy study areas” in Western states.

The idea is to identify federal land that might be be good for solar power plants.

Some environmentalists scoured maps of these solar study areas and got concerned.

Jeffrey Morgan is with Tahquitz Sierra Club in California.

Morgan says a solar plant can take up hundreds of acres, and construction could disturb desert tortoise and cactus habitat.

“They have no concept the desert is a vital, living place with a vast diversity of species, unspoiled landscapes and many, many other things. They they just see it as a waste-land. That’s just not true – it’s not a waste-land.”

The Bureau of Land Management says the “solar energy study areas” are just that – they’re for study – and the government would not let solar energy developers disturb critical wildlife habitat.

President Barack Obama’s visit
to Nellis Air Force Base near
Las Vegas has more to do with
what’s on the ground than it
does the fighter jets in the air.
Lester Graham reports on the base’s
solar energy project:

Nellis Air Force Base is home to the nation’s largest solar photovoltaic power plant. The system generates enough electricity to power the equivelent of more than 13,000 homes.

The Air Force’s partner in the solar plant is MMA Renewable Ventures. Matt Cheney is CEO.

Cheney says there are lots of advantages, starting with no need for foreign or domestic fossil fuels that emit greenhouse gases.

“It gets its energy from the sun. And, by the way, the sun is pretty predictable and effectively the energy we get from it is free.”

That’s not to say solar energy is free. The array at Nellis Air Force Base cost 100-million dollars to build.

The Air Force saves about a million dollars a year. So, it’s going to take a while to break even.

But as the demand for more solar goes up, the technology gets cheaper, in just a few years you might be able to get solar energy for about the same price as from coal-burning power plants.

The experiment to create a migrating flock
of whooping cranes in the Eastern US is having a
parenting problem. Chuck Quirmbach reports:

About 70 whooping cranes now migrate between the Southeast US and the Midwest.
Wildlife experts have been hoping that more pairs of the birds would start hatching eggs
and raising chicks in the wild.

This spring, at their northern home in Wisconsin, several female cranes did lay eggs and
sat on the nests during cold weather. But when it warmed up, the adult birds abandoned
their nests to look for food.

George Archibald is co-founder of the International Crane Foundation.

“If there is a food stress, when it becomes warmer their drive to feed may increase much
more than when it’s cold.”

Some of the crane eggs were saved and hatched out by wildlife centers.

A report from environmentalists concludes the
American West is getting hotter faster than the rest of
the globe. Lester Graham reports:

Now, this report was not peer reviewed, but The Natural Resources Defense Council and the
Rocky Mountain Climate Organization insist the data show it’s gotten hotter in the West
when you compare the last five years to the global average during the last century.

Theo Spencer is with the NRDC. He says water is always important in the West, and
this climate change is causing problems.

“The Colorado River Basin, which provides water for about 30 million people in the West, the temperature over the past 5 years increased 2.2 degrees. So that’s 120% more than the rest of the globe.”

The report says the Colorado is in a record drought – and that affects Denver,
Albuquerque, Las Vegas, Phoenix, Los Angeles and San Diego.

Straining Water Supplies in the Southwest

  • Nancy and Dave Tom bought this home near Apache Junction, Arizona. They have to haul all the water they use with their pickup truck, so they quickly learned how to conserve. (Photo by Mark Brush)

Many areas in the Southwest are booming. With all this new

Transcript

Many areas in the Southwest are booming. With all this new
development, pressures on water supplies are growing. Mark Brush takes
a look at the lengths people go to, to get water in the desert:


Nancy and Dave Tom used to get their water from a city water supply.
That was back when they owned a home in Tempe, Arizona. Like a lot of
people in the area, they had a pool, plants that needed water year
round, and a green lawn out back. Not exactly a desert scene. It took
a lot of water to support their lifestyle.


But life in Tempe was getting crowded. And when somebody rang their
doorbell and offered to buy their house for almost twice what they paid for
it, they jumped at the chance to move to a smaller town.


(Sound of birds)


They found a house for sale just outside of Apache Junction. It’s a
small city in the desert about an hour’s drive from Phoenix. The house
is at the foot of a dry mountain range and has spectacular views. But
the house didn’t have city water service:


“When we saw this piece of property we pretty much fell in love with it
immediately. And it was stated in the multiple listings that you did
have to haul water. And that the water trailer conveyed with the
property (laughs).”


(Sound of hooking up the truck)


To get their water, Dave Tom hooks up a trailer with a big plastic
water tank. He tows the trailer about 4 miles into Apache Junction.
There’s a water filling station here. He gets about 90 gallons of
water for each quarter dropped into the machine:


(Sound of truck parking)


“I’ve got my four quarters here – we’re going to put it in the vending
machine and have at it.”


(Sound of quarter and water rushing)


He makes about two trips a week, so he figures they’re using about 600
gallons of water a week. That’s quite a bit less than the 6000 gallons
they were using in Tempe.


Some of the things they did to cut back were obvious. Since they no
longer had a pool – and they didn’t water a green lawn – that helped.
But in their new place, they also bought a high efficiency washer and
dishwasher. And, when they don’t have guests around, they cut down on
the number of times they flush the toilet.


And they’re not alone in trying to cut back on water use. Even their
neighbors who have a well are really careful with their water. Phil
Reinhart lives just up the road. He’s rigged up a system of gutters
and pipes to catch rain water:


“You see it drains the front of my house and it comes down these
gutters into these storage barrels. And then I have a little pump that
I use and a little twelve volt battery that I use to pump my washing
machine full and then my washing machine then discharges into my citrus
trees – this is a lemon – here, take a lemon back with you.”


Reinhart is careful with his water. And he’s worried that the
population boom will put a strain on his well.


(Sound of water)


The tank on David Tom’s trailer is full. He tries to shut the water
off:


“Alright we’ll push the shutoff button – and watch out, you’re going to
get wet… no the shutoff isn’t working. We’re going to dump 25 to 30, maybe 40,
gallons of water, which to me it’s a shame they need to come down and
fix this.”


(Sound of water flowing)


A lot of this water spilling onto the ground has traveled a long way to
get here. The Central Arizona Project pumps water from the Colorado
River 230 miles away.


“Rather than a river than runs downhill by gravity, we’re a river that
runs uphill by pumps. We’re the largest electric consumer in the state
of Arizona.”


Sid Wilson is the general manager of the Central Arizona Project. He
says most of the water pumped into this region is used for farming.
But with rapid development, that’s expected to change. More water will
be used to service the new homes sprawling out into the desert.


“The CAP right now provides 40% of the water to this area, 40%, and that will increase
some over time.”


Wilson says people are going to continue to move to the Southwest. So,
future water supplies will have to be developed.


Back at their home near Apache Junction, Dave Tom has finished filling
up their underground storage tank. It’s taken him two trips with the
trailer.


(Sound of gurgling)


His wife Nancy says their new home has changed the way they think:


“Life out here in the desert has given me a greater appreciation for
water. There’s a part of me that says this is how everybody should
live in the desert. That they should have that awareness of their
water usage and embrace the fact that you live in the desert rather
than trying to change it into a lush tropical paradise.”

Blazing New Atv Trails in Parkland

  • Advocates of special trails for ATV riding say the trails would reduce environmental damage from uncontrolled use. (Photo by Stephanie Hemphill)

Managers at state parks across the country are scrambling to figure out how to deal with a

Managers at state parks across the country are scrambling to figure out how to deal with a
rising demand for trails for All-Terrain Vehicles. Stephanie Hemphill reports park
managers are finding it’s not easy to satisfy both fans who have fun on four wheel drive
vehicles and people who want a quieter time in the park:


As the name suggests, All-Terrain Vehicles are built to travel rough. ATVs power over
rocks and logs. Their go-anywhere knobby tires grip the land and take their riders just
about anywhere they want to go, and a lot of them want to go to public parks.


Whether it’s forests, dunes, bogs or a desert, riders say four-wheeling can be a fun way to
get out into nature. The vehicles are popular. Dealers are selling close to a million ATVs
every year, and sales are growing steadily. With that many people looking for a place to
play, states are scrambling to accommodate them.


In Minnesota, the state decided a long ATV trail might be a good way to attract tourism
dollars to a struggling rural area in the state.


Ron Sluka jumped at the idea. He’s the trail coordinator for a local ATV club. He’d been
wanting for years to build a trail in his area. Then he heard the state would pay for a
“destination” trail so well-built and attractive, people would come from all over to ride it.
Sluka thought it would be great news for his area.


He and county officials worked up a plan, but when it hit the local news, Sluka says a
few people raised a ruckus:


“The way it was presented to the people, eminent domain would take over in cases if
need be, and there were going to be up to 20 feet of your land taken for this trail. None
of the above is true, totally none of it is true, absolutely zero. But it’s too late: once
things are rolling, it’s rolling.”


Sluka says now, it’s hard to get a rational discussion of the issues. Beyond property rights
issues and worries about the ATVs being too loud, there are other concerns:


“The residents have kind of been left out of the loop.”


That’s Deb Pomroy. She lives near the proposed ATV trail.


Pomroy says most of her neighbors don’t mind the local ATV riders. It’s that idea of
drawing ATVs from all over the state that freaks them out, and Pomroy has her own reasons
for opposing a trail here, where the Cloquet River has its beginning: wood turtles.
Pomroy is a biologist. She says this area is a refuge for the turtles. They’re endangered in
most of their range, and listed as a threatened species in Minnesota.


Wood turtles bury their eggs in sandy soil. Pomroy says they would love to bury their
eggs in soil disturbed by ATVs, but the eggs wouldn’t survive:


“Even stepping on a nest, which is buried in soil, don’t know there are eggs there, is
enough to destroy the eggs.”


The trail is on hold for now, while county officials and ATV riders try to come up with
an alternative. Concern about damage to sensitive environmental areas is one of the chief
reasons many environmentalists don’t like the idea of letting ATVs into parks.


Jason Kiely is with Wildlands CPR, a national non-profit group that works to prevent off-
road vehicle damage on public land. He says fights over ATV trails are inevitable, as
long as public agencies don’t involve all park users in a comprehensive planning process.


“Primarily because off-road vehicles affect every other use of the forest so significantly.
So we advocate for doing comprehensive travel and recreation planning, not just trying to
carve off the ATV piece, but multi-stakeholder planning efforts that offer something to
everyone.”


Kiely says the US Forest Service and many state agencies have a lot of work to do, to
find the right balance between preserving nature and allowing ATV riders to have their
fun on public land

Tourists Drawn to A-Bomb Historic Sites

Sixty years ago, the first nuclear weapon was tested in the New Mexico desert, ushering in the dawn of the atomic age. A month later, two atomic bombs were dropped on Japan. It brought World War II to a swift end. There are tourists who are interested in the history of weapons of mass destruction. They might find the historical sites of the atomic age are hard to get to and still controversial. The Great Lakes Radio Consortium’s Mary Ann Colihan reports:


(Sound of monks chanting)


Keigaku Muchu is a Buddhist monk. Since the atomic bombs were dropped in 1945 on Hiroshima and Nagasaki, Japanese monks have walked back and forth between these two cities with a lantern that was lit by a flame captured from the smoldering ruins of their shrine, which had been destroyed.


In Zen Buddhism, sixty years is considered a sacred cycle. So this summer, they took a new pilgrimage to the Trinity Site in New Mexico. That’s where the atomic bomb was first tested. They wanted to close the cycle from where the atomic destruction started to where it ended in Japan. Keigaku says his journey helped him join spiritually to countless supporters who never want atomic weapons used again.


“So if people in northern America want to come physically to the Trinity site, that’s great too. But if they can’t come, they can be connected. I can connect with them spiritually.”


The monks were not alone on their 1600-mile overland trek from San Francisco in searing desert heat to the Trinity site. This walk was organized by Matt Taylor, co-executive director of the Global Nuclear Disarmament Fund. He says the walk has multiple missions.


“The main thing we’re trying to achieve is bringing the atomic claim that has been kindled from the ashes of Hiroshima back to the trinity site where it began, closing a sixty-year cycle.”


The Trinity test site is located on the White Sands Missile Range. The military holds an open house at the Trinity test site just two days per year. Jim Eckles is a spokesperson for the missile range.


“We get two to three thousand folks during each open house, and they come from all backgrounds, all walks of life, from all over the country. You’ll see young families, young kids, students on a science project, old people who were alive at World War II, veterans who come up and say, ‘I was getting ready to go to the Pacific and this saved my life,’ motorcycle gang members – you name it they come.”


Eckles says the Department of Defense is not likely to stop using the missile range just to welcome more atomic tourists. But the military is preserving the Trinity site.


“It’s significant because it is the first atomic bomb explosion or test site. It did change our lives. The Cold War had a different tone to it because of nuclear weapons and them hanging over our heads. And of course, they are still out there so they still influence us.”


And world headlines about nuclear proliferation still make history a flash point.


At another historic atomic site, the job of preserving is a little more difficult. John Isaacson is a resource manager in the environmental stewardship division at Los Alamos National Laboratories. There, the Manhattan Project was the code name for the top-secret program to build the atomic bomb. Isaacson says we’re still trying to understand what to make of the beginning of the atomic age.


“This is history that is gone through a number of different sort of re-analyses in the past fifty years since the end of the war and it’s still very alive for many people, a very real history for many people”


But there’s a problem. Manhattan Project buildings at Los Alamos are deteriorating. Most are wooden and were thrown up hastily by the U.S. Army Corps of Engineers. Although today, the public doesn’t get to see the site because it’s deep within a security zone, Isaacson says it should be preserved.


“I think the Manhattan Project is a real good example of this very controversial, unresolved historical process that, by preserving the buildings, it allows people to think about it, and it’s important to think about it.”


Isaacson wants us to keep the buildings in good repair for the day when they can be opened to the public. He’s getting some help. The Atomic Heritage Foundation in Washington D.C. is helping them and other Manhattan Project sites across the country raise eighty-eight million dollars to refurbish properties that are historically significant to the start of the atomic age.

Proposals to Limit Great Lakes Water Diversion

  • The Great Lakes from space (Color satellite photo courtesy of NOAA).

Leaders of the states and provinces around the Great Lakes have released two draft agreements to manage the region’s water supply. The proposals’ aim is to block any attempt to divert water from the lakes to drier parts of the world. The Great Lakes Radio Consortium’s Sarah Hulett reports:

Leaders of the states and provinces around the Great Lakes have released a draft agreement to
manage the region’s water supply. The proposal’s aim is to block any attempt to divert water
from the lakes to drier parts of the world. The Great Lakes Radio Consortium’s Sarah Hulett
reports:


There’s no immediate threat by outside interests to ship or pump large amounts of Great Lakes
water to the arid Southwest, or to any other part of the world that needs freshwater. And the
draft agreements aim to keep it that way.


There are two documents up for consideration by the public and policy makers. One would be a
binding compact between the states. The other would be a voluntary agreement between the
states and provinces.


Ohio Governor Bob Taft co-chairs the Council of Great Lakes Governors – which released the
plans.


“The whole effort is premised out of our concern that we have a legally enforceable framework,
and a clear standard.”


There’s already a federal law on the books that allows any one Great Lakes governor to veto a
diversion of water from the lakes. But there are concerns about challenges under the U.S.
Constitution, or free trade agreements.


The Great Lakes Charter Annex would require the approval of all eight states for any proposal to
divert more than a million gallons a day out of the basin. Even if a diversion is approved, there’s
a catch: whatever’s taken out of the basin would have to be returned once it’s used.


Noah Hall of the National Wildlife Federation says the practical effect of those requirements
would be a guarantee that the lakes don’t get pilfered by drier parts of the U.S….


“…Where they have growing populations and dwindling supplies of water, and they’ve been
looking at using the Great Lakes to meet their water needs for some time. I think they’ll
obviously see this agreement for what it is, which is a pretty large barrier – perhaps an
insurmountable barrier – to accessing Great Lakes water down the road.”


The agreement would also allow any three states to block withdrawals from within the basin of
more than five million gallons a day. Existing users would be grandfathered in, so only the most
mammoth project would likely come up for consideration – a new power plant, for example.
Hall says that means at most one project a year that would come up for review.


“But what it guards against is the threat of the absolute largest diversions. The massive
withdrawals. The ones that could by themselves harm or impact the Great Lakes, and lower lake
levels.”


Eventually, states would be required to put rules in place for managing smaller withdrawals
within the basin. Even under a best-case scenario, that wouldn’t happen for at least a dozen
years. But Ohio Governor Taft says the end result will be preservation of the lakes for future
generations.


“We have a responsibility as stewards of this precious resource – 20 percent of the world’s fresh
water supply – to protect and preserve it for the benefit of the people within the region, and that
is what the draft agreement is intended to accomplish.”


The plan is up for public review over the next three months. Each Great Lakes state would have
to sign off on the interstate compact. It would also require the approval of Congress. And the
fast-growing arid southwest has more representation in Congress every term.

In the wake of the World Summit on Sustainable Development in Johannesburg, South
Africa, there’s been a lot of talk about how to balance human needs with the health of the
planet. Ecologists have been trying to measure the impact of humans on the environment
for a number of years, with some sobering results. The Great Lake Radio Consortium’s Daniel Grossman went to the New
York Botanical Garden recently to gauge mankind’s ecological footprint.


[Rain forest sounds, misters, tinkling of water, rain falling on leaves]


To get a good sense of the impact humans are having on earth, you could travel for weeks
on intercontinental plane flights, river boats and desert jeeps. Or, as Columbia University
biologist, Stuart Pimm suggested, visit a botanical garden. There, under the glass and
ironwork of a conservatory, Pimm says you can see a resource that humans are
over-using – Earth’s most important resource, its plant-life.


“We’re sitting in the rain forest here at the New York Botanical Society. And it’s a riot of
green.”


Professor Pimm says here beneath the misters in the Tropical Rain Forest Gallery is a
good place to start a whirlwind tour of Earth’s greenery. The air is heavy with moisture
and sweet-smelling.


“Rain forests are some of the most productive parts of the planet. They grow extremely
quickly and they are therefore generating a lot of biological production.”


What Pimm calls biological production most of us know as plant growth. Biologists say
all this green growth in tropical forests and elsewhere on Earth is the foundation upon
which all life rests.


“Everything in our lives is dependent upon biological productivity – everything that we
eat, everything that our domestic animals eat.”


And everything that every other animal eats as well. In a recent book, Pimm painstakingly
tallies up how much biological productivity we use. He starts with the rain forest. In the
last 50 years, loggers and settlers have cut down 3 million square miles of lush tropical
forests. Much was cut down for subsistence agriculture, a purpose Pimm says it serves
poorly.


“Although the tropical forest looks rich and productive, it is a very special place. And
when you chop that forest down the areas that replace it often become very, very much
less productive.”


[Sound of walking around conservatory]


Pimm speaks of the toll on greenery of cities and roads and of land converted to farming
in temperate regions such as the U.S. Midwest. Then, trekking along the botanical
garden’s gravel paths, he leaves behind the tropical mists and steps into the dry heat of a
Southwestern desert. Deserts and other dry lands are not very productive, but they
account for a substantial fraction of Earth’s land surface. Most of it is grazed by flocks of
sheep, goats, camels and cattle, often causing severe damage to vegetation. When these
uses are added to the other impacts of humanity on earth’s bounty, the results are
surprisingly large.


“What silence has shown is that we are taking 2/5ths of the biological production on land,
a third from the oceans. And that of the world’s fresh water supply, we’re taking half.”


[Fade out sound of conservatory. Fade up sound of Texas frogs.]


[Sound of plane engines]


Frogs and toads croak out a spring mating ritual in a concrete drainage ditch. Nearby, a
pilot practices maneuvers in a small plane occasionally drowning out the amphibian
serenade. Living in culverts, sharing the night with droning engines, these wild animals
are never completely free of human influences. From his Stanford University office,
Professor Peter Vitousek says wherever you look, the din of human activities is
interrupting and crowding out other species. Vitousek made one of the first attempts to
tally the impact of people on plant productivity in 1985.


[Frogs fade out in time for Vitousek’s act]


“The message to me was that we are already having a huge impact on all the other species
because of our use of the production of Earth and the land surface of Earth. That’s not
something that our models predict for some time in the future or something that we’re
guessing at on the basis of fairly weak information. It’s something that we’re clearly
doing now. That’s already happening.”


Many ecologists say this conclusion is beyond doubt. What they can’t say is whether
human domination of so much of nature’s output is good or bad. University of Minnesota
Professor David Tilman says as a member of the human race himself, he appreciates the
comforts in clothing, shelter and food our lifestyles buy us. And he acknowledges that the
survival of our own species is probably not imperiled – at least for the moment – by the
destruction of others. Still, he wonders if someday we’ll regret today’s resource intensive
practices.


“I think the more relevant question to me is, ‘Are we doing this wisely?’ ‘Are we wisely
appropriating the resources of the world?’ So, my concern is that we live in a balanced
way – a way that is sustainable through generations – that we leave our children and
grandchildren the same kind of world that we have.”


An expert on the impacts of agriculture, Tilman says we’re using up more resources than
can be replaced. He says if we don’t grapple with these important issues now, by the time
the human population reaches eight to ten billion or so people later this century, it might
be too difficult for us to do enough to save the planet’s life as we know it today.
