If you’ve been waiting all season
for that quintessential taste of
summer – a juicy, ripe tomato from
the garden – you might be disappointed.
This year a tomato blight has swept
across the Northeast and is moving
into Midwestern gardens and farms.
Julie Grant reports:

Walk around this outdoor farm market in Cleveland and just say the words ‘tomato blight’ – nearly anyone in earshot has a story to tell.

Susan Myers says her home garden has given over to what she thinks is late blight.

“But it’s pretty serious. I mean, it’s like wiping out everything. I have lots of tomatoes and all the leaves are dropping. I’ve never, ever had that before.”

It doesn’t look like the farmers here are having trouble with tomato blight. Most tables are piled high with bright reds and yellows.

Skip Conant has a beautiful display of heirloom tomatoes – but he’s not sure how many more weeks he’ll have fruit to offer.

Conant: “We definitely have tomato blight. It’s been a cool, wet spring, so, yeah. There’s a fair amount tomato blight.”

Grant: “What does it look like?”

Conant: “You’ll see a yellowing and curling on the leaves and then the stem will turn brown. The plant will become a very brown. Die from basically the inside out or the bottom up.”

It’s hard to tell yet if these Midwestern growers are starting to see the same blight that decimated the northeast tomatoes.

Bill Fry is a plant pathologist at Cornell University. He’s studied late blight for 35 years. Fry says it looks like irregular shaped black spots, and can appear on the leaves or the fruit. It can destroy an entire crop in just a few days.

This is the same blight responsible for the Irish potato famine in the mid-19 century. Growers have seen late blight since then. But Fry says, not at these epidemic proportions.

“The fact that it’s just everywhere is, I think, is the major difference from previous years.”

This wasn’t the first cool, wet spring on record. So, why has the blight so bad this year?

It’s kind of ironic. Fry and his colleagues have been studying the problem and think it’s probably because so many people are gardening. Millions more than just last year. And lots of those people bought tomato plants at stores like Home Depot, Kmart, Lowe’s and Wal-Mart.

“Infected plants were sold throughout the northeast in the box stores. They were transplanted to home gardens and from there the pathogen disbursed to other home gardens, to conventional and organic farms.”

Fry says you might not even notice at the supermarket. Commercial tomato growers spray lots of fungicide to keep away the blight. But organic tomatoes are getting harder to find.

But chefs and tomato lovers who’ve waited all season for those locally-grown heirloom – and especially organic – tomatoes aren’t finding what they want in markets in the northeast.

Back at the Cleveland market, chef and restaurant owner Karen Small has been waiting for tomato season – and it finally hit. She depends on this market for her produce and stops at just about every stand.

But as Small hears farmer after farmer describe what they think is late blight – she’s worried about the weeks to come.

“We’re accustomed to having tomatoes well into September, and maybe that’s not going to happen this year.”

Small plans to go home and rip out the tomato plants in her home garden – after hearing late blight described so many times, she’s pretty sure her tomatoes are infected.

Where Nothing Can Survive

  • Shrimpers have seen their catches dwindle down from thousands of pounds of shrimp a day to very little due to the dead zone in the Gulf of Mexico. (Photo by Samara Freemark)

Every summer, thousands of
square miles of the Gulf of
Mexico die. The Dead Zone is
caused by pollution that flows
down the Mississippi River. It’s
runoff from factories, sewer
plants, and farms. And it causes
a lot of problems for fishermen
in the area. This year, the Dead
Zone is projected to be huge –
maybe the largest ever. Samara Freemark explains:

Every summer, thousands of
square miles of the Gulf of
Mexico die. The Dead Zone is
caused by pollution that flows
down the Mississippi River. It’s
runoff from factories, sewer
plants, and farms. And it causes
a lot of problems for fishermen
in the area. This year, the Dead
Zone is projected to be huge –
maybe the largest ever. Samara Freemark explains:

Imagine for a moment you’re a shrimp fisherman. Every day you send out your fleet to the same waters you’ve fished for decades. And your boats pull in a lot of shrimp- thousands of pounds a day, millions a year. And then one day, a normal summer day, you send the boats out, and they come back empty.

“You go from about 5000 pounds to nothing. It’s dead. That’s why they call it the dead zone.”

That’s Dean Blanchard. He runs the largest shrimp company in America- Dean Blanchard Seafood. 


Blanchard started seeing the dead zone about five years ago, but it’s not a new phenomenon. For a long time, nutrient fertilizer from upstream has run into the Mississippi River and from there, into the Gulf. It fertilizes big algae blooms– and when the algae decays, it sucks oxygen out of the water, making it impossible for fish to live there.

What’s new is how much fertilizer there is now.

“It’s not natural.”

Nancy Rabalais is a marine biologist at LUMCON. That’s Louisiana’s center for marine research. She says that over the past several decades there’s been a surge in fertilizer use in the Corn Belt states. That eventually ends up in the Gulf.

“We’re having 300 times more than we did in the 1950s. And it’s just over loaded the system.”

Rabalais predicts this year’s dead zone will be almost three times as big as it was twenty years ago – more than 8000 square miles.

Of course, the bigger the zone, the further out shrimpers like Dean Blanchard have to send their boats. That means a lot of wasted time, fuel, and wages.

And the zones might mean even bigger problems. Don Scavia is a professor at the School of Natural Resources at the University of Michigan.

“There’s a half a billion dollar shrimp industry in the gulf. And the shrimp depend on that habitat. And what we’re concerned about is that if the dead zone continues or even grows, that fishery may collapse.”

Congress is taking some measures to address the problem. Conservation programs in the Farm Bill work to reduce how much fertilizer farmers use, and how they apply it.

But there’s something else in the Farm Bill too – a lot of subsidy programs. Those pay for ethanol production. Which means more corn. Which means a lot more fertilizer.

“And what is debated every 5 years is how much funding will go into those conservation programs, relative to funding going into subsidy programs. And, by far, the subsidies win.” (laughs)

Scavia says for every $1 spent on conservation programs in the Corn Belt, $500 go to subsidizing crops.


Shrimper Dean Blanchard says he’s not sure how long he can live with that balance, especially as he watches the dead zone grow.

“How big is this thing going to get? If we kill the oceans we have problems. We have serious problems.”

But Don Scavia is hopeful. He says we know exactly how to reduce nutrient runoff – in fact, the basic programs are already in place. It’s just a matter of Congress choosing the right funding priorities.

Investigating the Organic Label

Congress wants to dig deeper into an ongoing investigation of the National Organics Program. The program puts the little green “USDA Organic” label on products. Mark Brush has more:

Congress passed a bill that will put more money toward investigating the USDA’s organic program.

Some organic watchdog groups say the National Organics Program has been too loose with its rules.

Mark Kastel is with the Cornucopia Institute. He’s one of those critics.

“They have been accused by reputable independent auditors of having ignored the will of Congress in how they are managing the organic program – favoring large factory farms – favoring unscrutinized products being imported from China – all this competing with our family farmers here in the United States.”

Kastel says that’s not the way it’s supposed to work.

But he says the USDA organic label is still the gold standard. And most producers follow the law.

He and some leaders in Congress say an expanded review of the program will make sure that little green label keeps its credibility.

Lawn Chemicals Cause Concern

  • Nationwide, farms use the bulk of chemicals. But one expert says homeowners are more likely to overuse pesticides and fertilizers. (Photo by Rebecca Williams)

New laws restrict pesticides and fertilizers in some cities. In recent years, farms have cut the use of chemicals. But, Rebecca Williams reports, some environmentalists say there are still far too many chemicals polluting streams and lakes:

New laws restrict pesticides and fertilizers in some cities. In recent years, farms have cut the use of chemicals. But, Rebecca Williams reports, some environmentalists say there are still far too many chemicals polluting streams and lakes:

There are 40 million acres of lawns and sports fields in the US. That’s only one-tenth of the amount of cropland.

But some experts say lawn pesticides and fertilizers can be more of a problem.

Charles Benbrook is the Chief Scientist with the Organic Center. It’s a non-profit research group in Oregon.

“While there are many more acres of corn and soybeans and cotton treated with pesticides than there are lawns, the rate of application on lawns in urban areas often is far higher than on the farm.”

And, he says people are more likely to get exposed to chemicals on lawns.

“There’s many more opportunities for significant exposures, particularly for children and pregnant women in urban areas.”

Nationwide, farms do use the bulk of chemicals. But Benbrook says homeowners are more likely to overuse pesticides and fertilizers.

Growing Food With Fumes

  • John Vrieze has a machine called a digester on his dairy farm that's used to turn manure into energy (Photo by Todd Melby)

Big dairy farms produce more than just milk. They also generate manure. Lots and lots
of it. That can be a problem for farmers and the environment. Todd Melby reports on a
technology that reduces manure and generates electricity:

Big dairy farms produce more than just milk. They also generate manure. Lots and lots
of it. That can be a problem for farmers and the environment. Todd Melby reports on a
technology that reduces manure and generates electricity:

(sound of suckling cows)

I’m on a dairy farm with John Vrieze and his daughter Brittany.

Oh, and some cows too.

Vrieze is a frugal man. A couple of winters ago, he had a contest with his son to see who
could use the least electricity. Vrieze was willing to go to extreme measures.

His daughter Brittany tells the story this way:

Brittany Vrieze: “He’d shut his fridge off in the winter time. Just use the outdoors for his
fridge. He was definitely trying to keep the kilowatts down.”

Todd Melby: “So what did he do? He just kept his milk in the porch?”

Brittany Vrieze: “Yup.”

Todd Melby: “And kept his frozen stuff outside?”

Brittany Vrieze: “Yup. Yup.”

Today, Vrieze isn’t just trying to save energy. He’s trying to create it.

(sound of cow moos)

From cow dung.

He’s got 1,600 head of cattle at his place here in western Wisconsin. Those cows produce
milk that gets made into cheese. But they also produce about 50,000 gallons of manure
— every day.

Farmers are required to store that manure in a big pool-like structure called a lagoon.
John Vrieze covers his up with a giant tarp.

“It would blow up from the biogas. It would look like a great big balloon or like the
Metrodome, for folks in the Cities. It’s from the nature decomposition of the manure. It
creates biogas. We would have to take that gas out from underneath the cover and flare it
off, which got us to thinking that there has to be a better way to use that energy than just
to flare it off.”

So Vrieze bought a $1 million machine called a digester. And he had help from the
federal government. They paid for a quarter of it. The government is interested in these
things because they can turn manure into energy.

And it turns out — the reason it’s called a digester — is a farm thing.

“A cow has four stomachs. We call the digester really the fifth stomach. All the stuff that
comes out of the back of the cow we then put in that digester.”

So this “fifth stomach” produces energy. However, it’s not ready-to-use energy. To sell it
as natural gas, it has to be about 95% methane. The gas from the digester is only about
60% methane.

(sound of pipeline burn off)

Another option is to convert it to electricity. But in the U.S., electricity is cheap.

Todd Melby: “You tried to sell it to the electric company, but they didn’t want it.”

Brittany Vrieze: “They’re not offering us enough money. So …”

After all this investment by Vrieze and the federal government, some of the gas he
collects is just being burned off into the air.

But maybe not for long.

Vrieze wants to build a greenhouse right on his Wisconsin farm so he can grow
vegetables and herbs in the winter. He says he’ll power it with energy from the digester.

“So, instead of your produce coming from 2,000 miles away – from the central valley of
California – wouldn’t it be neat if it came from 45 miles away?”

Vrieze is planning to use the water from the cow manure for his vegetables and herbs in
his greenhouse. And he’s got a machine similar to ones used at wastewater treatment
plants to clean the manure water.

But even with the digester, there’s still leftover manure he has to deal with. But Vrieze
says the digester makes it more manageable.

(blowing sound)

Some of the dry manure is blown into a pile where it’s gathered up and used as bedding
for the cows. In the summer, it’s also used for another purpose.

“It’s just a clean version of manure. It stinks a little bit. Most of the stink has been taken
out of it. And we mix this with potting soil and it works great for the plants. So …”

That manure/potting soil mix is sold to gardeners in the city. It’s another way for Vrieze
to be frugal and environmental at the same time.

Pharmaceuticals Down on the Farm

Congress is looking at restricting antibiotic use on livestock farms. The drugs are added to the animals’ feed to help stop diseases. Antibiotics also make the animals grow faster, and that’s good for farmer’s profits. Mark Brush reports… public health officials are concerned:

Congress is looking at restricting antibiotic use on livestock farms. The drugs are added to the animals’ feed to help stop diseases. Antibiotics also make the animals grow faster, and that’s good for farmer’s profits. Mark Brush reports… public health officials are concerned:

A lot of researchers say overuse of antibiotics on farms can lead to bacteria that are resistant to the drugs.

A bill in Congress would stop the drugs from being used to promote growth… and just use them to treat sick animals. The Preservation of Antibiotics for Medical Treatment Act is sponsored by the only micro-biologist in Congress. Representative Louise Slaughter from New York:

“And we’re watching a whole new classification now of bacteria, which was basically just a cut above harmless, become deadly. Particulary Staphylococcus aureus, which was as common as dirt, but now is MRSA. And can kill you in twenty-four hours.”

Slaughter says the Food and Drug Administration is not doing enough. So Congress has to step in.

The livestock industry says current regulations are enough.

Hiring Lambs as Landscapers

  • Louise Engel admits she and her husband were initially a little nervous about setting the lambs lose in their valuable vineyard. (Photo by Joyce Kryszak)

Transcript

Wine makers are shaking things up in their vineyards. Some of them use natural and organic methods to control pests and weeds instead of using pesticides. Now, one winery has discovered a unique, natural way to prune their grape vines. Joyce Kryszak visited the winery to get a first hand look:

At the Featherstone Winery in Southern Ontario there are 20 acres of perfectly manicured grape vines. They stretch out in neatly groomed rows across rolling green hills.

But no man or machine maintains this vineyard. There are 40 cute, little, wooly lambs on duty pruning the grape vines into tip-top shape.

David Johnson says he knows the idea of using lambs on his vineyard is a bit odd. Johnson thought so too when he first heard the idea. He found out about it visiting wineries in New Zealand.

“I didn’t believe them at the time. I thought they were having fun with a tourist and that this would be a big joke, some Canadian when he went back home, telling a story. So, yeah, I’ve taken a ribbing on the lamb thing, for sure.”

But Johnson ignored the jokes and decided to try it out.

His wife Louise Engel admits they were a little nervous at first setting the lambs lose in their valuable vineyard.

“We watched these lambs like hawks. I mean, all the staff were sitting out there and following them around – ‘did they eat any grapes, did they eat any grapes?’ But they didn’t. They’ve got very nimble little mouths and little teeths and little lips and they just eat around them.”

You see, pruning grape vines is delicate business. Only a targeted area of leaves is removed from the lower part of the vines to help the fruit grow better.

But Engel and Johnson say the lambs are perfectly designed to handle the job. The young, spring lambs aren’t tall enough and their necks can’t stretch up to reach the grapes. And, since they only weigh about 50 pounds, they don’t trample the soil. And, yes, their droppings do make excellent organic fertilizer.

(sound of lambs bleating)

Three years, and three flocks of sheep later, nobody’s laughing. Area vintners even have copied them; and for good reason. It would cost about $300 an acre to hire seasonal workers to come in for seven weeks in the summer to hand prune the vines. The lambs cost a fraction of that. And, when the pruning is done in August, off they go to the butcher.

Johnson says it turns out that free-range lambs fed a diet of grape leaves end up being pretty tasty.

“We sold them off last year to some caterers and some pretty nice restaurants, and they got back to us and said, ‘wow, these lambs are really special.’ They’re different; they’re almost veal-like in color and flavor and very, very lean. And they’re going to do lamb specials all month and pair it with our wines all month.”

But he admits there are some drawbacks.

They had a tough time finding enough lambs to do the job. There are about fifty million of them in New Zealand. But, it turns out, they’re kind of sparse in Ontario.

Johnson says there are some logistical problems, too. Even some organic pesticides are toxic to lambs. And, there’s all that fence building and moving around to limit the lambs’ access, so they don’t over-prune.

Still, they think it’s worth the hassle. Engel says the lambs fit in beautifully with their philosophy of sustainable farming and diversity in the vineyard.

“They’re lovely, tranquil, placid things, and there’s something almost biblical about having lambs roaming the place and wine here. And, it’s just, I don’t know, there’s just some itch that scratches that’s quite fulfilling.”

People visiting the vineyard enjoy watching the lambs too.

Customers enjoy lunch on the veranda as they look out on the pastoral scene. And, of course, they have a little wine. And one of the top selling wines is Black Sheep Reisling.

Food, Inc. Exposes Industry’s Secrets

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Dollars and Streams

  • A creek runs through Melvin Hershberger's farm in Holmes County, Ohio. He was able to clean up the water with money from the Alpine Cheese Company. The company needed to offset phosphorous pollution from its factory, so it pays farmers to reduce their manure runoff. (Photo by Julie Grant)

When you hear about dead zones in the Gulf of Mexico and the Great Lakes, they’re largely caused by pollution draining from the farm belt. It can take a long time and a lot of money to reduce pollution at factories. So they’re starting to pay farmers to cut pollution instead. Julie Grant explains:

When you hear about dead zones in the Gulf of Mexico and the Great Lakes, they’re largely caused by pollution draining from the farm belt. It can take a long time and a lot of money to reduce pollution at factories. So they’re starting to pay farmers to cut pollution instead. Julie Grant explains:

When you eat cheese, you might not realize that something so delicious creates a lot of waste. And that waste – that pollution – ends up going into the drain. It eventually ends up in rivers and lakes.

(sound of a factory)

We’re at a cheese factory in Holmes County, Ohio where they make nearly 60,000 pounds of cheese a day.

The big stainless steel vats look immaculate. But our shoes are wet.

Bob Ramseyer is CEO of the Alpine Cheese Company.

He says the floors are covered with water because the equipment is constantly being washed.

“We have a pre-rinse – that goes to drain. We have a final rinse, and that goes to drain. And we have all the floors that are flushed down and so forth, so that all ends up as part of the wastewater.”

The cheese factory’s wastewater includes not only those caustic chemical cleaners, but wasted milk by-products. One milk nutrient is the chemical, phosphorous.

About a decade ago, the Environmental Protection Agency told Ramseyer that the cheese company had to reduce the phosphorous it was releasing into the nearby river. Ramseyer was concerned.

“The equipment alone was going to cost a half million dollars. We projected it was going to cost between a half million dollars and a million dollars a year in operating costs. So we were looking for any way we could to reduce that cost. That’s where we got into the nutrient trading program.”

Alpine Cheese was among the first to negotiate what’s called a nutrient – or water quality – trading program. Instead of reducing the phosphorous coming from his factory, he pays farmers to reduce manure – another source of phosphorous – from washing from feedlots into the river.

(sound of cows)

Mervin Hershberger is an Amish dairy farmer with 125 acres and 54 milking cows.

(sound of a stream)

His farm looks like a postcard – beautiful hilly green pasture.

But a lot of the manure was washing off his farm into the streams. Herberberger says the cows were grazing right around the water.

“With the cows being in the creek we could see dirty water. The rocks were covered with dirt from cow’s waste. You walk through the stream, you’d kick up dirt and waste from the cows.”

Hershberger didn’t like it, but he didn’t have money to change it.

So when the County Soil and Water Conservation District held a neighborhood meeting to explain that Alpine Cheese was going to pay to reduce pollution from nearby farms, Hershberger saw a way to afford to clean up his farm.

He did about a dozen projects to reduce manure run-off into the water, like building a fence to keep the cows out of the stream.

And the little creek is bouncing back:

“As of now, it’s just totally clean, what you see. For the minnows and all the critters that are in the creek.”

Hershberger gets paid for the amount of phosphorous he keeps out of the water.

About 25 other farms in Holmes County are doing similar projects to reduce water pollution. And Alpine Cheese foots the bill. In exchange, the company doesn’t have to clean up wastewater coming from the cheese factory.

It’s a lot like a cap and trade program on water pollution.

There are a growing number of small programs like this around the country. But some people are trying to create water trading projects on a much larger scale.

That would mean a factory in one state might be able to pay farmer in another state. Eventually, all of the thousands of factories in just one river basin could pay farmers enough to reduce dead zones like the one in the Gulf of Mexico and in some of the Great Lakes.

Coral Conservation in the Caribbean

  • The island of Bonaire is somewhat of an anomaly in the Caribbean due to its remarkably preserved coral reefs (Photo by Ann Dornfeld)

Scientists say nearly half of the coral reefs in the US are in bad shape.
Many are dead. The situation is similar in much of the world. But not
everywhere, as Ann Dornfeld found on the Caribbean island of Bonaire:

Transcript

Scientists say nearly half of the coral reefs in the US are in bad shape.
Many are dead. The situation is similar in much of the world. But not
everywhere, as Ann Dornfeld found on the Caribbean island of Bonaire:

(sound of waves on shore)

Jerry Ligon was working as the on-board naturalist on a small Caribbean
cruise ship when he first saw Bonaire.

“And I saw how clear the water was. And I’d been able to compare, during
my stint on the cruise ship, other islands in the Caribbean, and I realized
how special Bonaire was. So that was at the end of my contract, so I
decided to stay here. And I’ve been here for 15 years!”

It’s wasn’t just the clarity of Bonaire’s water that made Ligon stick around. It
was the remarkably healthy coral reefs that lay beneath the waves.

“I can even talk to divers who come to Bonaire and they say, ‘What
fantastic diving!’ and they remember, ‘This is how the way it was in Cayman
Islands 25 years ago!'”

Ligon says the Cayman Islands might have even had more impressive
reefs than Bonaire’s back in the day. But coral throughout the US and
Caribbean has been in sharp decline for decades.

So how do Bonaire’s reefs remain intact?

Ramón de León is the manager of the Bonaire National Marine Park. He
says the island has an advantage in that it has no industries to pollute the
water.

The island is mostly undeveloped, which means relatively little farm and
lawn fertilizer run-off that can create marine algae blooms. And cool
upwellings in the region help balance the rising ocean temperatures. Warm
oceans can cause coral bleaching, which often kills the coral animal.

But de León says Bonaire really owes its healthy reefs to its history of
conservation laws. They date back to an era when such policies were rare.

“Bonaire start to protect sea turtles and turtle nests in 1961, back when
everybody was promoting sea turtle soups and nailing shells in the walls.”

By the end of the 1970s, Bonaire had banned spear fishing and made it
illegal to damage coral. For years, divers have been required to pay a
sizeable fee and take an orientation course before they’re allowed to dive
on the island. That helps them avoid touching the coral, which can kill it.

De León says the island still allows too much fishing. So several years ago,
he told the island’s fishermen they needed to choose a no-take zone to let
the reefs recover.

“I refuse to decide myself. I give the fishermen some prerequisites that they
have to have to close, and they chose which area. Is not my number-one
option, but is their number-one option. So I have to respect that.”

De León says because the fishermen chose the no-take zone, something
important happened. Compliance is high.

For all of Bonaire’s success in coral conservation, there are still some
problems. De León says its reefs suffer from leaky septic tanks and boat
pollution. And there are few of the large predator fish that used to maintain
population balance on the reefs.

But the island is a haven for researchers like Mark Patterson. He designs
underwater robots at Virginia Institute of Marine Sciences.

Last year he led a NOAA expedition to use robots to map Bonaire’s reefs.
He says the island’s reefs are valuable as a baseline by which other reefs
can be judged.

“If you’re an up-and-coming marine scientist and you go to a lot of the coral
reefs on the planet now, you might think that all coral reefs have always
look like this. And they haven’t! So the fact that we’ve got some pristine
reefs left is very important, and we’ve got to work very hard to protect them
because it shows us how the ecosystem should look and used to look
around the planet before things started to go downhill.”
