The bald eagle came close to extinction
before strong measures were taken to help pull
it back. The eagle was protected by the Endangered
Species Act for 40 years. And the government banned
toxic compounds such as DDT that caused damage to the
eagles’ eggs. Bob Allen caught up with researchers
who are monitoring the health of the birds. They’re
finding the birds are still being exposed to toxic
chemicals:


We’re on a steep, heavily wooded hillside about a mile above a
barrier dam on the Muskegon River in Michigan. The land is part of a private
church camp. So, human intrusion on the site is low. And the
pond behind the dam provides plenty of food for eagles rearing
their young.


Once every five years researchers are permitted to come here and
take young birds from the nest.


“Usually we try to keep people about a quarter mile away from the
nest. And that way we don’t have human disturbance that
would cause them to fail.”


Bill Bowerman is a wildlife toxicologist from Clemson
University. He first became part of this eagle survey as a grad
student at Michigan State more than 20 years ago, about the time
researchers began taking blood and feather samples.


Wildlife veterinarian Jim Sikarskie says eagles sit atop
the aquatic food chain, so any contaminants in the ecosystem
eventually show up in them:


“The contaminants that are in the plasma from the blood and
from the feathers then help us evaluate the quality of the water in
the area around the nest. So we do birds from different watersheds
every 5 years as part of the water quality surveillance plan.”


The nest is a tangled mass of twigs in an aspen tree swaying in a
strong breeze about 60 feet off the ground. As the research team
approaches, the female lifts off and begins to circle and squawk
just above the tree-tops.


They lay out syringes and test tubes on the ground. Walter
Nessen gets ready to climb the tree. He’s worked with
Bowerman monitoring sea eagles in his native South Africa.


Walter buckles into his harness and straps a pair of climbing
spikes to his boots. He has the kind of wiry strength and agility
that makes for a good climber. He prefers not to use gloves to
handle the eaglets because he relies on a sense of feel between
his hands and their legs:


“Immature birds, nestlings, are quite delicate because their
feathers are not hard-pinned. In other words, there’s still
blood circulating inside the feathers as it’s growing. One has
to be careful not to bend them or break them because they
will not develop further. That’s the most important thing.
The other thing is you need to take care the birds have big
claws. It’s one of the first things developing on the birds so
they can attack you and claw you and scratch you and that
kind of thing.”


Walter wraps his climbing rope, really a polyester-covered steel
cable, around the trunk of the tree, locks it into his harness and up
he goes.


First he checks nestlings to be sure they’re old enough and in
good condition before lowering them down in a special padded
“eagle bag.”


With young eagles on the ground, everyone becomes hushed and
businesslike. Bowerman writes down the eaglet’s weight and
other measurements. They’re four to five pounds with some
down-like feathers still clinging to them. Most prominent are
their dark beaks and yellow-orange claws.


Sikarskie carefully drops a cloth hat over an eaglet’s head to keep
the bird calm. Then, he talks a young grad student through
taking her first blood sample from the underside of a delicate
wing.


The two nestlings are examined for parasites. Then, they’re leg
banded, tucked gently back in the bags and hoisted aloft. They’re
out of the nest for maybe fifteen minutes.


Places like this, far upriver from the Great Lakes, were refuges
for eagles back in the DDT era. Eagles survived here because
fish couldn’t pass above barrier dams on the rivers and carry their
toxic burden with them, and Bowerman says the difference is still
noticeable today:


“If you live along the Great Lakes you still have higher levels
of PCBs. You still find DDE, which is the egg shell thinning
compound that caused the eagle’s decline in the first place. If
you’re in an area like this which is upstream of the Great
Lakes, there’s much less level in these inland birds.”


Eagle research in Michigan extends back 47 years.
Bowerman calls it the oldest continuous wildlife survey in the
world. It’s a record that documents the recovery of a species in
trouble, but sometimes the information has a more immediate
impact.


Bowerman says some years ago, tests on baby eagle’s blood
from Michigan showed a spike of an unknown chemical. Lab
tests found it to be from a product called Scotch Guard, a stain
repellent for fabric produced by the 3M Company.


When told about it, 3M hired Bowerman’s professor, John Geise,
to find out how widespread the compound was:


“John’s lab went all across the world collecting tissues of
different wildlife species. And they found it world-wide. And
that’s why 3M took scotch guard off the market.”


Bowerman worries that monitoring efforts will slack off when
bald eagles are off the Endangered Species list, and that new
contaminants will be missed. But he can’t help being inspired
by the birds’ recovery:


“Does it make you any more alive to watch that beautiful
eagle soaring around? And it’s really neat to see how many
there are now. So this is just spectacular.”

Eagles to Fly Off Endangered List?

Bald eagles could be taken off the endangered species list soon.
Rebecca Williams reports bald eagles have reached their highest numbers
since World War II:


The U.S. Fish and Wildlife Service says there are just under 10,000
breeding pairs of eagles in the lower 48 states. That’s up from a
record low of just 400 breeding pairs in the 1960s.


For many years, eagles were seen as predators and shot. After World
War II, the pesticide DDT weakened the birds’ eggshells… so they
couldn’t reproduce.


Valerie Fellows is with the U.S. Fish and Wildlife Service. She says
they’ll decide whether to take the eagles off the endangered species
list by the end of June:


“We can determine at any point if populations start to plummet,
that we can re-list them and add them
to the Endangered Species Act.”


Fellows says bald eagles also have other safety nets. They’re
protected by several federal laws that make it illegal to kill or harm
the birds.

Delisting the Bald Eagle

Federal wildlife officials have proposed removing the bald eagle from the endangered species list. In the lower 48 states, bald eagles have recovered from around 400 nesting pairs in the early 1960’s, to more than 7-thousand pairs today. The Great Lakes Radio Consortium’s Erin Toner reports:

Federal wildlife officials have proposed removing the bald eagle from
the endangered species list. In the lower 48 states, bald eagles have
recovered from around 400 nesting pairs in the early 1960s, to more than
seven thousand pairs today. The Great Lakes Radio Consortium’s Erin
Toner reports:


Major environmental groups hailed the government’s proposal to remove
the bald eagle from the endangered species list.


Doug Inkley is senior science advisor for the National Wildlife
Federation, which helped lead the bald eagle recovery.


“The success of recovering our nation’s symbol…the bald eagle…
demonstrates that with the right resources and with cooperative action by
all of those involved, the Endangered Species Act does chart a successful
path to recovery.”


The U.S. Fish and Wildlife Service will take public comment until May
17th on the proposed de-listing of the bald eagle. It was added to the
endangered species list in 1967, after becoming nearly extinct because of
the use of the pesticide DDT.


Some biologists are calling the proposed de-listing premature, saying the
bird’s numbers haven’t rebounded everywhere, and that its habitat still
needs protection.

Drama is a unique way to connect children with their textbooks.
That’s why a play on the achievements of Rachel Carson might be coming to
classroom near you. The Great Lake Radio Consortium’s Lisa Ann Pinkerton
reports on how the life of one prominent environmentalist is teaching
students about science:


The office of Professor Buck Favorini is in a tall gothic tower. It was the inspiration for Gotham City in the first Batman movie. Inside his tower at the University of Pittsburgh, Professor Favorini has his own superhero story. His children’s play, Rachel Carson Saves the Day, is a science lesson in the language of children.


“We have used the sort of idiom of superheroes in the play, because it’s a way of teaching kids about science that they can understand simply by looking keenly at the world around them.”


Favorini says if Rachel Carson hadn’t been smart, bold, and risky, pesticides like DDT might still be in wide use. Some people honored her for her book Silent Spring. Others saw her as a reckless, unpredictable scientist threatening their chemical superhero.


“People made some of the worst chemicals in the world launched a very expensive campaign to undermine Rachel Carson’s scientific abilities partly based on the fact that she was a woman.”


Perched on a hill, overlooking another part of Pittsburgh, is Spring Hill Elementary.


LOUDSPEAKER: “Third, fourth, and fifth grade teachers, we’ll call you to the
assembly as soon as the staff sets up in the auditorium. Thanks.”


The staff is actor Elena Block and stage manager Josh Futrell. They hustle to assemble silver pipes of scaffolding and hang two white screens.


“There are two DVD players that do these great images that do these scenes from science and pictures of Rachel Carson. Sort of become this floating back drop.”


While Block is on stage as Rachel Carson, Futrell controls the images, music, and the voice of “Little Rachel’s” Mother.


FICTIONAL MOTHER: “Alice in Wonderland is your breakfast companion again.”


FICTIONAL RACHEL: “Oh Mama, I love this book, and so does Candy when I read it to her.”


(Sound of barking)


The play begins with Rachel as a young girl. She grows up quickly to become a marine biologist with the U.S. Fish and Wildlife Service. Her scientific observations reveal chemicals like DDT are contaminating waterways and silently creeping up the food chain.


FICTIONAL RACHEL: “This is the bird. The bird that ate the clam, that ate the
plankton, that swam in the ocean, fed by the stream, that carried the
chemical Jack-”


CHILDREN: “Sprayed!”


(Sound of clock ticking)


FICTIONAL RACHEL: “I’m in the late afternoon of my life and I am so angry. The next book I right is going to make a lot of noise.”


(Sound of “Mighty Mouse” theme)


To write Silent Spring, the passionate scientist/writer rips away her dress
to reveal a green superhero suit. Quickly Super Rachel is attacked by a man who’s face is hidden behind a long
pointed gasmask.


(Sound of fighting)


The Chemical industry attacks Rachel for her ideas. Images of nature and chemical compounds flash on the screens behind them. Super Rachel uses cartwheels and karate chops to over power Chemical Man.


(Sound of hip hop battle)


CHEMICAL MAN: “The bugs are buggin’ me.”


FICTIONAL RACHEL: “The chemicals are killin’ me.”


CHEMICAL MAN: “We’re gonna hit ’em from the air.”


FICTIONAL RACHEL: “How can you not care?”


Super Rachel prevails and DDT is officially banned in 1972.


(Sound of applause)


After the play, it’s clear the students of Spring Hill Elementary were paying attention.


GIRL: “She was trying to think of better ways to kill the insects instead of just polluting them.”


BOY: “I think she thought it was really important about the environment, and I think that’s good, because most people don’t.”


Not everyone agrees with the conclusions of Rachel Carson’s book, Silent Spring. Some scientists say Carson misrepresented existing 1950’s data on bird reproduction, and others say the very threat of malaria in developing countries should trump possible environmental threats of DDT. Actress Elena Block thinks despite these criticisms, Rachel Carson’s story has much to offer children.


“If they can sort of come away the idea with the idea that you can exact change being yourself from the place that you’re from. I think that’s pretty good, don’t you?”


Rachel Carson Saves the Day starts its second year of touring this fall, and perhaps it’s fun, multimedia look at environmental protection will inspire America’s next generation of intrepid scientists.

Cormorant-Killing Policy Ruffles Feathers

  • Cormorant populations have risen exponentially from their previously dismal numbers. (Photo courtesy of the NOAA)

Across the Great Lakes region, the recovery of the cormorant
is booming. But some anglers and resort owners think the cormorants are eating too many of the fish that people like to eat.

Across the Great Lakes region the recovery of the cormorant is booming. But some anglers and resort owners think the cormorants are eating too many of the fish that people like to eat. In some areas, wildlife managers have resorted to killing cormorants on popular fishing lakes. In one case, critics say there’s not enough evidence to justify the killing. The Great Lakes Radio Consortium’s Stephanie Hemphill reports:


Larry Jacobson is the third generation in his family to run the Hiawatha Beach Resort on Leech Lake, about two hundred miles north of Minneapolis. Three years ago, on fishing opener weekend, all of his twenty-one cabins were full. This year, he had no guests. Jacobson says the word has spread that fishing is down on Leech Lake. He blames the cormorants. The birds nest on a small island in the south end of the lake. Eight years ago, there were fifty nests; last year, there were two thousand five hundred.


“The cormorants eat about a pound fish a day. The way the population was just exploding out there, you could see writing was on the wall, that this was really going to make dramatic impact.”


Jacobson says his guests are still catching big walleye, but the smaller, pan-sized walleye are getting hard to find.


There are several reasons why the walleye population might be down, but Jacobson and other business owners blame it on the cormorants, and they’ve asked the Department of Natural Resources to do something about the birds.


“Leech needs to be maintained as high quality fishery. There’s such an economic impact to the area from walleyes, that if you don’t maintain it that way, everyone’s going to be suffering.”


(Sound of boat motor)


Resource officials are responding to the resort owners’ concerns. The Leech Lake Band of Ojibwe owns the island. John Ringle is wildlife manager for the tribe.


“Okay we’re headed right at Little Pelican Island right now.”


Little Pelican Island is about three acres of sand and scruffy shrubs. Hundreds of cormorants cover the shore. Ringle says they fish out here in the open waters of Leech Lake.


“They’re omnivorous so they’re eating all sorts of different varieties of fish. Right now they’re probably eating large numbers of perch.”


Ringle is working with state and federal agencies to reduce the number of cormorants nesting here, eating fish, and crowding out other birds, such as the endangered common tern.


Normally, cormorants are a federally protected bird, just like eagles. That’s because they were almost wiped out by the insecticide DDT before it was banned in 1973. But a new rule allows resource officials to harass and even kill cormorants where they’re damaging other wildlife.


This summer, workers are sitting in hunting blinds on Little Pelican Island, shooting cormorants. They use air rifles to make as little noise as possible, so the other cormorants aren’t spooked away.


So far, they’ve killed more than two thousand birds. They plan to leave about five hundred nesting pairs alive. Ringle says nobody’s happy about shooting cormorants, but he says he thinks it’s necessary.


RINGLE: “My philosophy is that as mankind utilizes the resource, we have to manage them, we’re not in finite supply.”


HEMPHILL: “Do you think we know enough to manage them?”


RINGLE: “Not really. I think the public is demanding action prior to any conclusive study being conducted.”


And that’s a big problem for Francie Cuthbert. She’s a professor and cormorant researcher at the University of Minnesota. Cuthbert says the agencies that want to cut down the cormorant population skipped an important part of the management process: finding out what’s actually happening on Leech Lake.


“They’re really being driven by complaints from citizens and resort owners who are concerned about local economics, and who just don’t like the birds; they’re afraid of the numbers. If we responded to all natural resources conflicts this way, we’d be in a state of chaos.”


Cuthbert says even with the cormorants’ dramatic comeback since the days of DDT, there still aren’t as many as there were a hundred years ago. She says rather than kill cormorants, wildlife officials should try to boost the number of fish.


The state of Minnesota is working on that. It’s stocking Leech Lake with walleye for the first time this year. Conservation officials are studying some of the birds they killed to find out what they’re eating. And the state is also limiting what size of walleye anglers can catch so the fish can recover.


That makes resort owners like Larry Jacobson nervous, because he says a lot of anglers don’t like the limits. But at least he’s glad someone’s doing something.


“The fishery is a business, there’s no question about that. If you want to sustain our economy in this area, you’ve got to manage the lake.”


Workers will continue shooting cormorants occasionally through the summer. And the control effort could continue. Experts say it’ll take several years for the fish to recover enough to draw anglers back to the lake.

Cost of Taking Eagle Off Endangered Species List

With more than 7600 breeding pairs in the continental United States alone, the American Bald Eagle has made a remarkable comeback.

With more than 7600 breeding pairs in the continental United States alone, the
American Bald Eagle has made a remarkable comeback. A new proposal to remove the
bird from the Endangered Species list is expected soon. But that means removing a
powerful safety net that can affect future research, monitoring and habitat protection.
The Great Lakes Radio Consortium’s Sally Eisele reports:


In the history of the Endangered Species Act, only a dozen or so of the more than 1200
plants and animals listed as threatened or endangered have actually recovered. The eagle
may be the latest to join that little group.


(Young birder: “I see a big birdie…”)


This is a pretty unlikely spot for an eagle — a manmade wetland by a landfill in a busy
airport flight path on the outskirts of Detroit. But state wildlife biologist Joe Robison
shows this young visitor the bulky nest across the marsh where two adult birds are
teaching their gangly fledglings to fly.


“Something just landed in the tree out there. Oh. That’s the other juvenile. This is the
first time I’ve seen them flying this year. They look like they’re flying good though.”


These birds are among more than 400 pairs in Michigan monitored by state and federal
wildlife officials. The eagles are banded, the nests are watched and when a bird dies it
ends up in the freezer of wildlife pathologist Tom Cooley.


(sound of Cooley opening the freezer)


“Lots and lots of ’em. You can see that one was a road kill along I-75…”


Right now, Cooley’s freezer is brim full of dead birds stacked like frozen Thanksgiving
turkeys in plastic bags. Road kill has become the leading cause of death among eagles
he examines, but Cooley says they still investigate suspicious looking deaths for the
heavy metals and pesticides—like DDT—which once caused the eagles’ demise.


“Birds that kind of send up a red flag to us are adult birds that are in poor condition and
you don’t see a reason why they could be in poor condition. Those are the ones that we
especially look at for pesticide analysis because there are still the organochlorines out
there. The DDTs are still picked up by eagles or still contained in eagles. Those
pesticides can cause real problems for them and actually kill them.”


Cooley sends tissue samples to another state lab for analysis. But the testing is
expensive. And with the eagle on the way to recovery, it’s not as urgent. Right now, he
says all the samples he sends are being archived—shelved basically. That means the
testing won’t be done until the money is available.


“I never like archiving anything if I can help it. You’re probably not missing anything
but that kind of data is always nice to have if you can get it right away and look at it right
away.”


The question is, if it’s hard to get funding for monitoring and testing now—while the bird
is still on the Endangered Species List—what happens when it’s taken off the list? The
reality, say state and federal wildlife experts, is that budget priorities change as a species
recovers. Ray Rustem heads Michigan’s non-game wildlife program.


“There’s not enough money for every species. So you try to take a species to a level
where you feel comfortable with and you take money and apply it to another species to
try to recover.”


The federal Endangered Species Act requires the Fish and Wildlife Service to monitor
what it terms a delisted species for five years. After that, responsibility largely shifts to
the states. That concerns groups like the National Wildlife Federation. Attorney John
Kostyak questions whether states can really afford to protect fragile species and their
habitat over the long term.


“That’s going to be an issue with any delisting. A tough question that we’re going to
always be asking is: all right assume you go forward with delisting—how are you going
to be sure the species doesn’t turn right around and go back toward extinction again?”


With some species, that means habitat management. With others, like the recovering
gray wolf, it means public education—teaching people not to kill them. With the eagle, it
means ensuring that the birds are not threatened by the pesticides, heavy metals and
newer chemicals that contaminate the fish the eagles eat. Because of the bird’s
importance as an indicator species, Fish and Wildlife biologists are hopeful banding and
testing programs will continue after delisting. But it will likely mean finding new ways
to pay for them.

Eagle Soaring Off Endangered Species List

The American Bald Eagle is expected to come off the endangered species
list soon. Once a victim of hunting and pollution, the eagles are
rebounding, but scientists say monitoring must continue, for the sake
of the eagles and the sake of the environment. The Great Lakes Radio
Consortium’s Bob Kelleher reports:


If you’re looking at all, it’s hard to miss the bald eagles here. The
majestic birds glide overhead, or silently perch on a waterfront tree.
Their nests – made of branches – fill the treetops – sometimes ten feet
across, close to the lakes of Northern Minnesota’s Voyageurs National
Park.


Twenty years ago you might have been hard pressed to spot America’s
national symbol. Park Biologist Lee Grim says, it was obvious that
eagles were struggling.


“We saw how some of these birds were ill, and sick, and they had avian
pox and things. Something was keeping them from being healthy.”


An eagle found here in 1989 had the highest blood concentration ever
found of contaminants like the chemical PCB.


“So, we wanted to know why is that up here in Northern Minnesota, in
the middle of a beautiful, you know, almost wilderness area.”


It’s still a mystery how industrial chemicals like PCB’s get here, but
we do know what’s hurt the bald eagles in the past. The insecticide
DDT made bird eggs fragile – more likely to break under an eagles
weight than hatch. And Grim says DDT was all over the place. It was
sprayed on the region’s forests to kill insects like the spruce
budworm.


“DDT is pretty much everywhere, it has been, you know. And it’s a
pretty long lived chemical.”


At the top of the food chain, chemicals like DDT accumulate in the
eagle’s bodies. Sick eagles can indicate a poisoned environment. To
test the environment, you test the eagles.


(snd of climbing)


A naturalist is scaling 90-feet up one of the park’s White Pine trees
to the huge nest at the top. The parent eagles circle overhead –
noisily upset. There’s a pair of hatchlings – fuzzy, beaky, and
surprisingly big 8-week old bald eagles. They have bright yellow feet,
with shiny black, and what will become very dangerous talons. Soon,
one’s squirming in an orange bag, and lowered into the hands of
graduate students Faith Wiley and Katie Parmentier.


(snd of students talking about baby eagle)


In minutes, the young female is back up; short a few feathers for
mercury testing; and a little blood for other chemical tests. There’s
a pair of metal bands riveted around her ankles.


Bill Bowerman is an environmental toxicologist from Clemson University.
His testing proves that chemicals like DDT and PCB’s are slowly going
away, but chemicals were only part of the problems for bald eagles.
Man was another problem. It took decades to get people to stop
shooting eagles; or to catch them accidentally in beaver traps, but
it’s better now.


“It’s evident, when I go out to landowners that have eagle nests on
their property, that they know how to manage their eagles; how to keep
people away; and how to protect that eagle during that critical nesting
period.”


It’s believed there were once half a million bald eagles in North
America. As people spread, by the 1950’s, bald eagles nearly vanished.
In the lower 48 states, the last few hung on in places like the Great
Lakes.


In Voyageurs Park, bald eagle numbers have jumped from seven nesting
pairs in 1973, to 28 pairs today. There are more than 7-thousand
breeding pairs nation wide, but there are always new threats. One of
the nation’s first victim’s to West Nile disease was the bald eagle in
New York area zoos. Bowerman says several pair are missing now in
Michigan, and there are always new chemicals. Traces of poly
brominated flame retardants are doubling in the Great Lakes basin every
3 to 5 years. Bowerman says the chemical industry needs strict
monitoring.


“As long as we maintain our vigilance about the environmental toxicants
that are being created each year, we should be having the eagles
protected.”


Bowerman supports de-listing, but doesn’t want the birds in the
predicament they were twenty years ago. An official announcement of
the bald eagle’s de-listing is expected later this year.

“Problem” Cormorants to Be Killed?

The U.S. Fish and Wildlife Service is proposing a rule that would allow people to kill the Double-Crested Cormorant. The bird was once federally protected. The Great Lakes Radio Consortium’s Chris McCarus reports:

The U.S. Fish and Wildlife Service is proposing a rule that would allow
people to kill the double-crested Cormorant. The bird was once federally
protected. The Great Lakes Radio Consortium’s Chris McCarus reports:


The double-crested Cormorants have become a nuisance because they eat a
lot of fish and their waste destroys trees and grass. The U.S. Fish and
Wildlife Service wants tribes and conservation officials to identify Cormorants that pose a problem. They would shoot the birds with shotguns or destroy their
nests and eggs. Commercial fish farmers would also have the right to destroy
the birds.


Ray Rustem is with the Michigan Department of Natural Resources. He
says wildlife officials will need a coordinated effort to be successful.


“Well, these are very intelligent birds and hunting is going to be a lot more
difficult because they will learn very quickly if there is a boat around they are going to get shot at
and they’re going to avoid those kind of things.”


In the ’70’s, the pesticide DDT had killed most of the double-crested Cormorants in the Great
Lakes region. They’ve since recovered and now number about 1 million.


The federal government is accepting comment on its proposal to kill these birds.


For the Great Lakes Radio Consortium, this is Chris McCarus.

Falcons Hatch a Complete Recovery

Thirty years ago, peregrine falcons were nearly extinct in the Midwest. Today, environmental protection efforts have succeeded in returning the fast-flying raptors to their earlier numbers… and even better. The Great Lakes Radio Consortium’s Diane Richard has more:


A twenty-year program to restore peregrine falcons is seeing new signs of
success this summer: hatchlings.


Experts estimate that as many as 300 peregrine falcons will hatch this year.


In the sixties, DDT all but wiped out the population. But the peregrine
falcon is back, thanks to a ban on the pesticide and conservation efforts by the Midwest Peregrine Falcon Restoration Program.


Since the eighties, this regional partnership has released birds bred in captivity. Today, it’s monitoring peregrine falcons at 30 sites across 13 U.S. states and two Canadian provinces.


Mark Martell is a conservation coordinator with the restoration program. He
says the challenge now is to keep the population thriving.


“We don’t have a lot of experience with taking a species from zero
individuals up to a stable population. So we want to make sure this
population stays stable.”


To do so, Martell says researchers will spend the next 20 years keeping tabs
on the falcons and their chicks.

Distancing Ourselves From Our Food

Not too long ago, the fall harvest season was celebrated for its bounty of locally grown fresh fruits and vegetables.

Not too long ago, the fall harvest season was celebrated for its
bounty of locally grown fresh fruits and vegetables. Thanks to the
globalization of our food system we can now buy fresh produce 365
days of the year. Great Lakes Radio Consortium commentator Suzanne
Elston says the end result is that most of us have no idea where our
food actually comes from.

As a kid I grew up near the Okanagan Valley near Canada’s west coast.
The area was famous for its fruit trees. During harvest time, my
parents would stop at a roadside stand and buy a basket of cherries
and put then in the back seat for my sister and I to entertain
ourselves with. The first thing we’d do is look for double hung
cherries to hang over our ears like drop earrings. Then we’d bite one
of the cherries and use the sweet juice to paint our lips and cheeks.
We’d throw back our heads and do our very best Marilyn Monroe
impression before diving into the remaining fruit. We’d fill our
mouths to the point of bursting, and then spit the pits at each
other, giggling and laughing in a fit of harvest bliss.


This delicious ritual remains carefully etched in my mind because
it’s so rare today. My kids can eat fresh fruits and vegetables from
around the world on virtually any day of the year. They’ve already
tasted things that I didn’t even know existed when I was a kid –
kiwis from New Zealand, exotic star fruits and Jamaican plantain for
example.


On the surface, this seems like a good thing. Thanks to international
trade and modern storage technologies, we are no longer restricted by
local growing seasons and soil conditions. But in having so much,
we’ve actually lost sight of the process of growing food. Most of us
are about three generations away from having to go to the henhouse to
pick up the eggs on the family farm. And if our ancestors didn’t
actually grow their own food, they purchased it from a neighbor who
did.


Today instead of going out in the back garden and picking a tomato
for dinner, the tomato that ends up on your supper plate may have
traveled thousands of miles by truck. It’s then delivered to a
distribution center, shipped by yet another vehicle to your local
supermarket, and then given a ride home in the back of the family
van. This idea of being removed from our food source is something
called distancing.


Distancing not only adds to the cost of food, but it also places a
heavy toll on the environment. Trucking fresh produce across vast
distances burns a whole lot of fossil fuel – a major contributor to
both global warming and smog. Some of the countries that we import
produce from don’t have the same strict guidelines that we do about
pesticides. The result is that along with fruits and vegetables, in
some cases we’re also importing chemicals such as DDT that we banned
decades ago.


And then there’s the produce itself. Although it’s technically fresh,
it has to be picked long before it’s ripe in order to survive the
journey. Then it spends several days – or perhaps even weeks – before
it shows up on store shelves. Sure it looks great, but for those of
us who have experienced the taste of freshly picked fruit, it’s not
even in the same ballpark.


Which is perhaps why cherry is now my least favorite flavor. It’s so
far removed from the delicious cherries of my childhood, that I’d
rather not taste it.
