Part 1: A Long History of Dioxin Delays

In 1981, Valdus Adamkus was appointed to a regional Environmental Protection Agency office. One of his jobs jobs was to study dioxin pollution that got into the Great Lakes. His office compiled a report that said dioxin is a cancer risk, and that a Dow Chemical plant in Michigan was responsible for some dioxin pollution. (Photo source: Dantadd at Wikimedia Commons)

Dioxin pollution has been present in a
watershed in central Michigan for more
than thirty years. People around the
country might think it’s just a local
issue, but there was a time when this
very same pollution problem made national
news. In the first part of a series
on Dow and dioxin, Shawn Allee met the man who took the issue to Congress
and who feels it should make news again:

Transcript

In 1981, President Ronald Reagan appointed Valdus Adamkus to a regional Environmental Protection Agency office. From the get-go, one of Adamkus’ jobs was to study dioxin pollution that got into the Great Lakes. His office compiled this report that said dioxin is a cancer risk, and that a Dow Chemical plant in Michigan was responsible for some dioxin pollution.

Adamkus says his bosses in Washington called this report “trash.”

Adamkus: “We simply refused to retreat from our findings.”

Allee: “Did they ask you to retreat from your findings?”

Adamkus: “Yes, unfortunately we almost got instructions, let’s use a very mild word, to change our report. And that brought us Congressional hearings, which probably the entire country was watching on TV networks.”

Koeppel (ABC Archive ): “An official at the EPA today said the Dow chemical company was allowed to participate in the redrafting of a report on dioxin contamination that had been critical of Dow. And that official charged that Dow’s involvement was at the direction of the EPA’s acting chief.”

That was March 18, 1983, and ABC’s Ted Koeppel wasn’t the only one covering the Congressional hearings.

All the TV outlets caught this line from Adamkus –

Adamkus ( ABC Archive ): “It’s unethical, unusual, unprofessional to get the internal document approved by outside company.”

So, higher-ups in the EPA allowed Dow to edit the report critical of the company. But, in some ways, Adamkus won. His boss got ousted and Ronald Reagan gave Adamkus a civil service award for integrity.

As for Dow Chemical’s involvement?

For a month, I asked for comment.

A Dow spokeswoman said the company was interested in talking about the future, not the past.

Adamkus eventually left the EPA and he became President of Lithuania. But back in the US, there was a surprising follow-up to his fight over dioxin.

Mary Gade was a young staff attorney back when Adamkus was on TV. Twenty-three years later, President George W. Bush appointed her to Adamkus’ old job. When Gade arrived – dioxin was still a problem in Michigan.

“My staff in the region characterized this as probably the worst dioxin contamination in the country.”

And, she saw it as a national issue.

“You’d like to expect that your government will function appropriately, that corporations will act responsibly and that you can be assured of a safe and healthy environment for you and your family.”

So, Gade ordered Dow Chemical to clean up some hot spots.

“They would either do the work themselves or the federal government would go forward and do it on their own, and then go back and sue Dow to cover our costs.”

Michigan politicians complained about Gade, and some state officials felt some of her actions were counterproductive. In May 2008, she was forced to resign.

Gade told the Chicago Tribune, it was for being tough on Dow.

The EPA hasn’t commented on that, and Dow denies any involvement.

Recently, Mary Gade’s old boss, Valdus Adamkus, returned to his old EPA office to say hello. He asked about the dioxin problem in Michigan, and he learned it’s still around – after all these years, and after all the trouble he and Mary Gade got from it.

“When I hear from them what enforcement actions are being still considered, and that they are not big progress in that respect, that’s what really bothers me and to me this is inexcusable.”

Dow and the EPA are negotiating a final resolution on cleanup right now.

But Valdus Adamkus knows details need to be worked out, and he says all of this has been promised before.

“God help them. I hope this is really coming to the end.”

Risk the Shot or Risk the Flu

A study by the Harvard School of Public Health finds that only 51% of parents nationwide plan to get their kids vaccinated against the new swine flu. (Photo courtesy of the Centers for Disease Control and Prevention)

Public health officials want people
to get vaccinated for swine flu.
But only half of parents nationwide
say they plan to get their kids vaccinated.
Many say they’re worried about vaccine
side-effects. Julie Grant reports some
government policies may have inadvertently
made people concerned about vaccine safety:

Transcript

Some of the schools near where I live in Ohio have absentee
rates of 20%. Kids are reporting flu-like symptoms. Some
schools are even closing down to keep more people from
getting sick.

At the same time, a study by the Harvard School of Public
Health finds that only 51% of parents nationwide plan to get
their kids vaccinated against the new swine flu.

The vaccine has a serious public relations problem.

One reason people are worried: thimerosal.

Thimerosal is a preservative used in vaccines. It prevents
bacteria and fungus from contaminating vaccine bottles.
Thimerosal is almost half mercury, by weight. And that
makes a lot of people nervous.

As a precaution, it was taken out of most American vaccines
about twenty years ago. But it’s still used a lot in flu shots.

Lynn Gregor has two little children. She’s been leaning
toward getting them vaccinated for swine flu.
But she just heard about thimerosal, and she’s concerned.

“Because even if it’s a teeny, tiny bit of mercury, which is
what that product is connected with. Because a teeny tiny
bit of mercury can have a big impact.”

The Centers for Disease Control says the type of mercury in
thimerosal is different than the kind that’s in thermometers.
Lots of people think thimerosal is linked with increased
autism rates. But public health officials say science does not
bear that out.

“There has been no credible evidence of a harm that’s linked
to thimerosal.”

That’s Donn Moyer. He’s spokesman for the Washington
state Department of Health. It’s one of six states that have
passed laws making it illegal to give young children and
pregnant women flu shots that contain thimerosal.

Moyer says the health department didn’t ask for the law. It
says thimerosal is safe. But, politicians wanted to appease
people concerned about thimerosal.

The state of Washington’s concern is not about the actual
safety of thimerosal, it’s about the public’s perception of
thimerosal.

“The goal was to maintain public confidence in vaccine
programs and to encourage parents to have their kids
vaccinated.”

But now that the new swine flu is here, Washington is
suspending its law. The swine flu seems to be hitting young
children especially hard, and Moyer says infants and
pregnant women should get immunized – even if the only
shots available contain thimerosal.

“We don’t see any credible risk of health effect from the
thimerosal and it could protect against a very, very serious
influenza infection.”

That seems like a mixed message to parents. And it’s part
of the confusion between the science and politics of this
issue.

(Fox news music intro)

Anchor: “We are tracking H1N1 and health officials here in
the US…”

On this Fox news report Dr. Kent Holtorf is labeled an
“infectious disease expert”, and he warns people against the
vaccine.

Holtorf: “And it’s been shown to cause autism in children
with mitochondrial dysfunction. It’s controversial, though
highly implicated.”

Anchor: “Would you give it to your kids?”

Holtorf: “I definitely would not.”

Some Right-leaning commentators are sharing their
suspicions about the vaccine from the government. And, on
the Left, one natural health newsletter put out a special
edition warning against vaccination.

This all leaves federal health officials with a big job to do:
use the preponderance of science to convince people that
swine flu is potentially more dangerous than the vaccine and
thimerosal.

The mother we talked to – Lynn Gregor – wants to protect
her kids from swine flu, and she’s thinking about getting
them vaccinated.

“If they don’t get it, I’m going to be really worried all winter.
I’m going to be really concerned.”

But when Gregor hears so many people are opting out of the
vaccine – and that some states actually ban thimerosal most
of the time – she’s not sure what to do.

Atrazine in Our Water

People have been concerned
about farm chemicals getting
into drinking water supplies
for a long time. A recent report
showed that the chemical atrazine
peaks, in many areas, in concentrations
much higher than previously thought.
Julie Grant reports there are
things you can do to protect your
family. But, finding out if you
have a problem is harder:

Transcript

Bob Denges is worried. His water is discolored. So he’s
called a water purification company to test it.

(sound of running water)

They’re running water in the basement utility sink. It’s kind
of orange-y looking. So, it’s an easy diagnosis: too much
iron.

“You can probably see in the toilet, upstairs just on the first
floor, that there’s some brownish, reddish discoloration
around the toilets.”

That’s not great. But at least you can tell when there’s iron
in the water. You cannot see or taste other water
contaminants such as weed killers like atrazine.

Tom Bruusema is the water filter expert at the National
Sanitation Foundation. They test and certify water filtration
devices. He says the first place you can check is your local
municipality – the folks that monitor water in your area.

“That would be the place to start. They are required, by
federal law, to measure a number of contaminants, produce
an annual report for their consumers.”

But recently an investigative report by the New York Times
revealed water contamination can spike in some places –
and local water officials might not even know about it.

That weed killer – atrazine – is applied on farm fields and, in a
lot of places, you also find a lot of atrazine in the water
during that time.

If you’re looking for it at the right time.

Sometimes it spikes for longer than a month. But some local
water officials only test for atrazine once a month, or only
once a year, and often it’s not during that peak application
season.

So people can’t really find out about atrazine levels for their
drinking water in those places.

Some water systems are spending lots of money to treat
drinking water to get atrazine levels down to what the federal
government considers safe levels.

But that might not be enough, according to some of the new
scientific evidence about atrazine.

Five studies published in peer-reviewed journals recently
have found evidence suggesting that small amounts of
atrazine in drinking water causes health problems. Even at
levels considered safe by federal standards, atrazine might
be associated with birth defects. Things like low birth
weights in newborns. Skull and facial malformations and
misshapen limbs.

Forty-three water systems in six states — Illinois, Indiana,
Iowa, Kansas, Mississippi and Ohio — recently sued
atrazine’s manufacturers. They want to force the company
Syngenta and its partner Growmark to pay for removing the
chemical from drinking water.

Steve Tillery is an attorney in the lawsuit.

“Some of them have gone to the expense to cleaning it
completely out of their water supplies, so that it doesn’t exist
at all. And they should, in our view, be entitled to
reimbursement of expenses for cleaning it completely out of
their water supplies.”

But, some water systems are not cleaning out atrazine
completely. And, as we mentioned, there are times when
some don’t know they exceed the federal safe drinking water
levels.

There is something pretty easy you can do if you’re worried
about your water.

Tom Bruusema of the National Sanitation Foundation says a
simple carbon filter can remove atrazine. Those are the
filters you can attach to the faucet or the pitchers you refill.

“So it’s a good investment. Certainly can help them if they
have those kinds of concerns, and particularly those living in
an area that’s known to have potential contaminants in the
water supply.”

But first people have to be aware of a possible problem.
And, too often, they are not.

Dioxin Deal One Step Closer

The federal government and a major
chemical company have reached an
initial agreement about cleaning
up one of the nation’s largest dioxin
pollution sites. But, Shawn Allee reports, the public will
have to wait a bit to examine the
fine print:

Transcript

Central Michigan has a dubious distinction: The Environmental Protection Agency
claims that a flood plain there has some of the highest dioxin levels ever found in soil.

That dioxin came from a Dow chemical plant decades ago. The EPA and Dow just
concluded negotiations over a clean-up deal.

Wendy Carney is with the EPA’s regional Superfund cleanup office. Carney says the
deal is not done, though.

“This agreement doesn’t actually contain any cleanup options. It also doesn’t
address any cleanup levels for the site. That would be a part of things we would talk
about with the public in a public forum to get their feedback on those issues.”

Carney says the EPA could unveil its agreement with Dow in two weeks.

The EPA suspects dioxins cause cancer and other health problems.

Seeing Snakes as Worth Saving

As kids, many of us come to see
snakes as frightening, evil creatures.
In some places, that ingrained fear
has taken a toll on the snake population.
Karen Kelly met up with some folks
who are trying to improve one snake’s
image – before it disappears:

Transcript

(sound of truck, bumping on a road)

George Sheffield drives his truck along the dirt path that leads to his family’s
vacation cottage. He keeps an eye out for long, black snakes.

“It might be a good day to see a snake. It was cold last night so they’ll be
looking for sun today to heat back up.”

Sheffield’s land is one of the few places where black rat snakes still thrive in
Ontario. They’re a threatened species here, partly because people have moved
into their habitat.

But also, because they’re often six feet long, so people get scared and kill them.
The black rat snake is the longest snake in Canada. It’s not poisonous, but it’s a
constrictor that eats small animals.

(sound of walking towards cottage)

Once we’re at Sheffield ‘s camp, he checks out one of the snakes’ favorite spots
– the roof of his cottage.

“The one time, there 3 or 4 out on the roof, with portions of others, with their
heads or tails sticking out of soffits. So they do inhabit the cottage. I wish they
didn’t, but until I fix it, I can’t blame them.”

Sheffield is one of a growing number of landowners who are trying to protect
the black rat snake. They’re putting up nesting boxes in fields and wooded
areas to give the snakes a warm and safe place to spend the winter.

But the biggest challenge is just convincing people not to kill them.

Kiesewalter: “Do you want to hold the snake?”

Children: “He’s pretty heavy.” “He feels kind of like rubber.”

Tobi Kiesewalter is a biologist at Murphy’s Point Provincial Park in
southeastern Ontario. It’s used by as many as 500 black rat snakes – as well as
a lot of campers, swimmers, and boaters.

It’s a perfect chance to teach people about the snake. So every day, Kiesewalter
takes a rat snake out of a cage in the visitor’s centre and tries to persuade people
to leave them alone.

“I hear about it all the time, people coming and telling us about how their dad
had killed snakes before. Kids will tell you anything. And, as with many
reptiles, the loss of even one mature adult can cause a dip in population because
we know they’re only reproducing every two years.”

There’s a lot of effort to help this snake. Culverts are dug under highways to
give them a safe route back and forth. There are road signs that say, “Please
brake for snakes.” There’s even an adopt-a-snake program.

But the fact is, the black rat snake isn’t in danger in other parts of North
America. So why save it here?

For George Sheffield, the answer is simple.

“I grew up with them here, I think it would be a shame if man’s activities
caused the end of another species in another area. We’ve already done way too
much to degrade the environment and the number of species, so anything
anybody can do is good.”

Is Your Playground Toxic?

Playgrounds are supposed to be
safe places for kids to play.
But Tamara Keith
has the story of a leaked memo
from the Environmental Protection
Agency that indicates there might
be a problem with crumb rubber:

Transcript

(sound of kids playing)

Shawn Clancy’s two sons are having fun running around a community play set. And if they fall, he says there’s plenty of crumb rubber. It’s made from recycled tires and it should stop them from breaking any bones.

“I’ve seen kids fall from far distances. I’ve seen the give. I’ve seen them get right back up and kids are playing with it. It’s fun to dig in. They can kind of play with it. It’s about 8 inches thick, so there’s quite a bit of it.”

Clancy and his neighbors like the fact that it lasts a long time and that it keeps old tires out of landfills. And they’re not the only ones.

(outdoor sound)

I’m outside of the White House right now, just on the other side of the fence. And somewhere on those grounds, probably behind some tall shrubs, there is a play set. It’s a new play set that Sasha and Malia, the first family got. And underneath that play set is a pretty thick layer of rubber crumb to protect the girls if they fall.

I don’t think anyone is suggesting that this exposure is good for kids. The only question is how bad could it be.

Jeff Ruch heads Public Employees for Environmental Responsibility. His group got its hands on some documents where scientists at the Environmental Protection Agency question whether there’s stuff in the crumb rubber that could be toxic to kids.

“What’s known is very very little. They list, I think it’s 30 toxic chemicals in one of the memos. And so far work has only been done on two of them.”

An EPA spokesman says the agency is doing a preliminary study of 4 playgrounds, looking for lead and volatile organic compounds. The results aren’t in yet.

The Rubber Manufacturers Association says there are more than a hundred studies showing scrap tires are safe in playgrounds and that environmental groups are over hyping the concerns.

Richard Wiles isn’t buying it. He’s senior vice president of the Environmental Working Group. And he feels like he’s seen this movie before – with arsenic treated wooden playground equipment.

“It was a really bad idea to use arsenic in this way and for about 20 years this is what we did.”

And kids all across the country were playing on this contaminated wood. But the thing is, initially arsenic treated wood seemed like a great idea, because it prevented decay – and made play structures safe and strong for years.

Parents might be left with the feeling that you just can’t win. Wiles thinks there’s another lesson.

“The basic problem is, we tend to use these products before we evaluate the health and safety concerns. We tend to just throw it out there without thinking that oh this is a surface that is made out of something that was previously considered hazardous waste.”

With all the alarm about very real arsenic problems, and yet to be verified concerns with crumb rubber, Donna Thompson says it’s easy to forget that playgrounds today are safer than they’ve ever been. She’s executive direction of the National Program for Playground Safety. For now she’s standing by crumb rubber, because it does such a good job of preventing broken bones.

“I’m not going to worry about it yet until I hear what the results are because I think sometimes we make too big a deal out of something and then it’s just not the case.”

The EPA says it will have results in a few weeks.

Pet Pythons on the Loose in Florida

Foreign animals that get released
in the wild usually don’t spark that
much interest. But when that species
is a giant snake, well, most people
sit up and take notice. That’s the
problem facing the state of Florida,
where Burmese pythons have moved in
to Everglades National Park. Now,
scientists are trying to figure out
if the snakes could spread to the
rest of the country. Samara Freemark reports:

Transcript

Meet South Florida’s newest invasive species – the 20 ft long, 200 lb,
Burmese python.

“They’re impressive animals. They’re really impressive animals. And
they’re breeding
like crazy out there.”

That’s python researcher JD Willson. He says the pythons probably started
off as pets –
until their owners got bored of them and dumped them in the Everglades. Now
those pets
have procreated their way into a huge wild population.

“Certainly thousands. Certainly tens of thousands. Some people have gone
as far as to
say hundreds of thousands.”

Willson says most pythons won’t attack humans. But they do pose a big
threat to local
ecosystems.

“These are snakes that are top predators. They eat alligators, they got a
bobcat record, a
couple of white tail deer. These are a predator that native wildlife are
just not prepared to
deal with. They’re not used to having a giant snake around.”

Florida lawmakers are considering putting a bounty on the pythons – paying
hunters to
kill them. And people in neighboring states just have their fingers crossed
that the
pythons won’t spread north.

But no one really knows enough about the snakes to come up with a good
control plan.

Willson and some other researchers are trying to change that.

“This is the python enclosure.”

They’ve built a little artificial habitat in South Carolina, surrounded
it with a really tall
wall, and filled it with 10 pythons. The researchers want to learn more
about how the
snakes behave in the wild, and see if they can make it through a winter
with freezing
temperatures.

(sound of door opening)

The snakes are tagged with radio transmitters, so the scientists can track
them and record
data on how they’re doing.

Freemark: “It’s safe to be in here?”

Bower: “Oh yeah, they’re not aggressive.”

Inside a student volunteer, Rick Bower, is tracking the snakes with a radio
receiver.

“As you sweep it across, you can see how the signal strength changes and
you get an idea
of where the strongest signal is coming from.”

The receiver tells us we’re basically standing right on top of one of the
pythons.

“Yeah, he’s right at our feet. Yeah, he’s down there.”

But we don’t see anything, even when Willson starts jabbing a stick at
the source of the
beeping.

“Somewhere within an 8 foot radius of where we are, there’s an 11 foot
snake. And he’s
hiding in this aquatic vegetation. And not only can we not see him, but
poking in the
vegetation doesn’t seem to be eliciting too much of a reaction.”

He’s a really sneaky snake.

Whit Gibbons is also working with the crew. He says that if the scientists
have so much
trouble tracking down their pythons, in an enclosed cage, using radio
transmitters –
there’s no way bounty hunters could make even a dent in the Everglades
python
population.

“So they find a hundred, so what. There’s a hundred thousand left. No
one’s going to find
100,000. I mean, we’ve got ‘em in a small enclosure, 10 big snakes,
over 75 feet of snake
if you add them up. And you can’t find them.”

Instead, Gibbons says people could opt for a harm reduction strategy- focus
on limiting
the spread of the snakes, try to protect species they threaten.

“One position is, ‘okay, they’re here, here’s what they can do to
us, or to our pets, or to
the wildlife. Let’s learn to live with them.’”

The South Carolina python study ends next summer. JD Willson says he’s
not sure what
they’ll do with the snakes afterwards. But he does know one thing –
they’re not going to
release them back into the wild.

The Environmental Protection Agency
is trying to figure out how it might
regulate greenhouse gases. Lester
Graham reports language in the
Clean Air Act is not helping:

The U.S. Supreme Court ordered the EPA to decide whether greenhouse gases are pollutants. The EPA is making the case that they are.

But setting rules to reduce those emissions is problematic.

The Clean Air Act says it you emit 250-tons a year of a pollutant, you need a pollution permit. 250-tons of CO2 a year is not a lot.

Jeff Holmstead worked in the EPA on air pollution issues during the last Bush Administration. Now, he’s a lawyer with the Washington DC firm Bracewell and Giuliani.

“You know, 250-tons of CO2 according to EPA would include most schools, most apartment buildings, any kind of commercial building. It just isn’t possible to develop permits for all of these sources.”

So the EPA plans to raise the amount to 25,000-tons. But, that’s not what the Clean Air Act says.

That’s one reason why the Obama Administration prefers a climate change law passed by Congress.

Close Contact Endangers Dolphins

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:

Transcript

(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.

Commercial fishing in the oceans of the US has done a lot to reduce
accidentally catching marine mammals such as dolphins. But there are
still problems. Ari Daniel Shapiro reports on concerns about one kind
of tropical dolphin called the false killer whale:

Transcript

Jim Cook has been a fisherman in Hawaii for 18 years.

“You know, it used to be real simple: catch a fish, sell it, and go
back out and try and catch another one.”

Now he owns a company that operates six fishing vessels. Cook’s
ships catch deep swimming sashimi-grade tuna that ends up in sushi
restaurants across the US. They use a technique called longline fishing.

“We have around 45 miles of mainline to which we attach floaters
and 2200 to 2500 baited hooks.”

“The regulations imposed on the Hawaii longline fishery are
probably the most restrictive regulations on any longline fishery in the
world.”

That’s Bill Robinson. He’s an administrator with the National
Marine Fisheries Service. And these regulations he’s talking about are
meant to reduce bycatch. That means catching marine animals other than
the tuna. As a result of these policies, sea turtle bycatch has dropped
by more than 90-percent and seabird bycatch by 95-percent.

Things are looking up, but now there’s another problem. The numbers of
another kind of animal – the false killer whale – are declining. No one
knows why they’re disappearing. It might be related to longline
fishing, but it’s just not clear.

Robin Baird’s a biologist with Cascadia Research.

“There’s a whole variety of lines of evidence that imply the false
killer whale population around the main Hawaiian islands has declined
dramatically over the last 20 years. And I think it’s clearly the most
serious conservation or management issue for whales and dolphins in
Hawaiian waters today.”

Baird thinks the decline is partly related to fewer numbers of tuna
and other species false killer whales eat. He also suspects that the
false killer whales might be moving farther offshore, where they could
get hooked when trying to eat the tuna caught by the longline fishery.

So the question is: should the National Marine Fisheries Service come up
with even more regulations for the longline fishery in case more false
killer whales move offshore looking for tuna.

Bill Robinson with the Fisheries Service isn’t so sure that they
actually go that far offshore.

“That’s speculation, and it may or may not be true. What we
don’t really know is what the range of each population is.”

So, really, at this point, it’s anyone’s guess why the false killer whale numbers are declining.

The biologist, Robin Baird, is concerned that nothing’s being done.

“Unless something is done to change the factors that are
influencing the population, it probably will continue to decline.”

The environmental group Earthjustice and a coalition of
conservation groups have sued the National Marine Fisheries Service over
failing to develop a plan to protect the false killer whales.

The agency has not responded officially to the lawsuit yet. But Bill
Robinson says an action plan is in the works.

“Hopefully by the fall, we’ll be able to not only appoint the
team, but have the team begin work on a take recovery plan that will
make recommendations to the agency to reduce the incidental take of
false killer whales in the fishery.”

Such a plan might end up costing the commercial fishers money. But
Jim Cook says he’s willing to pay. That’s because false killer whales
pick fish off his lines. They eat the caught tuna before the fishers
can haul them in. That can mean a lot of lost income.

“We would very much welcome any methodology almost
irrespective of cost because we’re suffering quite a bit economically as
it is.”

But the National Marine Fisheries Service first has to find that
methodology.
