Mississippi Delta’s wildlife, farmers, and restaurant owners battle climate change

Record flooding, human-made channels and environmental disasters have exacerbated the already harsh effects of climate change in Louisiana’s Mississippi Delta, impacting the region’s coastal wildlife and seafood supplies. Special correspondent Joshua Landis reports on how local oyster farmers are coping as part of our series, “Peril and Promise” in partnership with Nexis Media News.

Hari Sreenivasan:

The Mississippi Delta is one of America’s most picturesque and economically important regions. But the changes humans have made to it, made worse by climate change, have shaken up coastal wildlife and seafood supplies. NewsHour Weekend Special Correspondent Josh Landis has our story. It’s part of our initiative: Peril and Promise: the Challenge of Climate Change, produced in partnership with Nexus Media News.

Josh Landis:

Debbie Fountain and her husband are oyster farmers in the Gulf of Mexico. Restaurants up and down the East Coast are a booming market for seafood from these parts. A demand the Fountains would like to harness for their small business. And they see themselves as more than just seafood vendors.

Debbie Fountain:

I feel a stewardship, you know. We’re doing something that’s renewable. You grow an oyster, they filter the water, you can feed people, it’s a huge beautiful source of protein. What’s not to love about it? A lot of these cages become little habitats, little hatcheries. See the little crabbies? And all the other little crazy things in there?

Mr. Fountain:

Would you like another oyster?

Josh Landis:

Sure, I’ll have another one.

Mr. Fountain:

Salty, huh?

Debbie Fountain:

They have a complicated flavor. It’s a complicated mineral mix.

Josh Landis:

But last year, the couple confronted the volatile new reality of the Mississippi River even though their oyster bed is nearly 100 miles east. Rain and snow across the Midwest had swelled the river to record levels. The Army Corps of Engineers had little choice but to open a massive ‘safety valve’ called the “Bonnet Carre” spillway for an unprecedented 123 days. The gates add a temporary new branch to the river, lowering water levels in the main channel.

Josh Landis:

If I had been here earlier this year, I’d be facing a wall of water more than a mile wide. At that time, water was moving North from the river to Lake Pontchartrain across this vast expanse at a rate of nearly 200,000 cubic feet per second. The arrival of so much fresh water from the Mississippi into the saltier coastal water of the Gulf threw off a delicate balance. Local volunteers found the remains of more than150 dolphins and twenty-three turtles. Scientists on WLOX’s newscast in Biloxi, MS, blamed the loss of marine life on the influx of fresh water.

Tim Morgan:

Additional non-salt water that comes in decreases the salinity in their environment and that causes some major problems with these guys.

Debbie Fountain:

Two parts per thousand salinity. You can stick your finger in it and it tastes like fresh water. These animals are simply not made for that kind of fresh water. That kind of flexibility. For us it was 100% mortality. We lost about probably 14,000 oysters in that event.

Josh Landis:

Author and chef Melissa Martin sees the changes showing up in her kitchen. She’s the founder of The Mosquito Supper Club in New Orleans.

Melissa Martin:

I created these tables so we could start a conversation about South Louisiana and talk about sustainability and food and life and the environment. What we do here is try to give people a meal that they would have at my grandmother’s house or my mom’s house, serving the food that I grew up eating. I get worried when I peer into the future about running a restaurant. I won’t be running a restaurant based on seafood from other places. I will always be running a restaurant based on what I could get here. And that may mean that one day that I’m not a seafood restaurant. And that’s a really sad thought, but that’s kind of the reality of where we are.

Josh Landis:

Martin’s kitchen hasn’t suffered solely from the intrusion of fresh water into salt water. Salt water moving into fresh has been an even bigger problem. The numerous oil & gas production facilities in the area utilize a maze of man-made channels, allowing saltwater to invade marshlands, causing erosion and destroying seafood-rich habitat.

Melissa Martin:

Terrebonne Parish used to be one of the highest oyster producing places in the state, but once the saltwater intrusion started happening because of the oil fields, we lost pretty much all of our oyster beds. The amount of shrimp that we have has changed because we just don’t have estuaries for them to live in, you know they’re just being eaten away by salt water. It’s a huge red flag that we’ve got some major things happening.

Debbie Fountain:

For us, environmentally, our markers have become some of these big disasters. A huge hurricane. A huge oil spill. A huge flood situation. I would hate to think that that’s the only measures that we have of our time, but it seems like right now those are the measures of our time. We’re gonna have to do what farmers all over America do. Try and insure if we can. And a lot of prayer. Because we have no control over some of those things.

Josh Landis:

Aerial photographer Ben Depp, seen in PBS’s 2019 series Rivers of Life, is one of many artists in New Orleans for whom the Delta is a core inspiration. But in exploring the iconic landscape, he knows he is documenting a disappearing world.

Ben Depp:

Everywhere you look, you see the thousands of miles of canals cut through the wetlands, which caused saltwater intrusion, which killed the vegetation, and caused the ground to erode. You can see the marsh just fragmenting apart.

Josh Landis:

Some channels pre-date those created by the oil industry. They were made to transport trees during a surge in coastal logging in the late eighteen and early nineteen hundreds when Louisiana was the nation’s largest producer of timber.

Ben Depp:

This place used to be a thriving ecosystem, mostly forested with Cypress and Tupelo – just this expansive, wet hardwood forest full of alligators and fish. Some areas here are still incredible, but it’s kind of just the edges of what this place used to be.

Josh Landis:

The bald cypress can grow to 1,700 years old on this coast. Some scientists estimate it would require about that amount of time to undo humans’ impact on the Mississippi Delta. In the meantime, Debbie Fountain offers her own plan.

Debbie Fountain:

We all have to be better stewards of what we use and how we behave and what we do. All of us have to become better stewards.

DELTA IS ONE OF AMERICA'S MOST

PICTURESQUE AND ECONOMICALLY

IMPORTANT REGIONS.

BUT THE CHANGES HUMANS HAVE MADE

TO IT, MADE WORSE BY CLIMATE

CHANGE, HAVE SHAKEN UP COASTAL

WILDLIFE AND SEAFOOD SUPPLIES.

OUR STORY.

IT'S PART OF OUR INITIATIVE,

"PERIL AND PROMISE: THE

CHALLENGE OF CLIMATE CHANGE,"

PRODUCED IN PARTNERSHIP WITH

NEXUS MEDIA NEWS.

>> Reporter: DEBBIE FOUNTAIN AND

HER HUSBAND ARE OYSTER FARMERS

IN THE GULF OF MEXICO.

RESTAURANTS UP AND DOWN THE

EAST COAST ARE A BOOMING MARKET

FOR SEAFOOD FROM THESE PARTS,

A DEMAND THE FOUNTAINS WOULD

LIKE TO HARNESS FOR THEIR SMALL

BUSINESS.

AND, THEY SEE THEMSELVES AS MORE

THAN JUST SEAFOOD VENDORS.

>> OH, I FEEL A STEWARDSHIP, YOU

KNOW.

WE'RE DOING SOMETHING THAT'S

RENEWABLE.

YOU GROW AN OYSTER, THEY FILTER

THE WATER, YOU CAN FEED PEOPLE.

IT'S A HUGE, BEAUTIFUL SOURCE OF

PROTEIN.

AND WHAT'S NOT TO LOVE ABOUT IT?

A LOT OF THESE CAGES BECOME

LITTLE HABITATS, LITTLE

HATCHERIES.

>> Reporter: SEE THE LITTLE

CRABS INSIDE.

>> SEE THE LITTLE CRABBIES?

AND ALL THE OTHER LITTLE CRAZY

THINGS IN THERE?

>> Reporter: DELICIOUS.

>> SALTY, HUH?

>> THEY HAVE A... A COMPLICATED

FLAVOR.

IT'S A COMPLICATED MINERAL MIX.

>> Reporter: BUT LAST YEAR, THE

COUPLE CONFRONTED THE VOLATILE

NEW REALITY OF THE MISSISSIPPI

RIVER, EVEN THOUGH THEIR OYSTER

BED IS NEARLY 100 MILES EAST.

RAIN AND SNOW ACROSS THE MIDWEST

HAD SWELLED THE RIVER TO RECORD

LEVELS.

THE ARMY CORPS OF ENGINEERS HAD

LITTLE CHOICE BUT TO OPEN A

MASSIVE SAFETY VALVE CALLED THE

"BONNET CARRE" SPILLWAY FOR AN

UNPRECEDENTED 123 DAYS.

THE GATES ADD A TEMPORARY NEW

BRANCH TO THE RIVER, LOWERING

WATER LEVELS IN THE MAIN

CHANNEL.

IF I HAD BEEN HERE EARLIER THIS

YEAR, I'D BE FACING A WALL OF

WATER MORE THAN A MILE WIDE.

AT THAT TIME, WATER WAS MOVING

NORTH FROM THE RIVER TO LAKE

PONTCHARTRAIN ACROSS THIS VAST

EXPANSE AT A RATE OF NEARLY

200,000 CUBIC FEET PER SECOND.

THE ARRIVAL OF SO MUCH FRESH

WATER FROM THE MISSISSIPPI INTO

THE SALTIER COASTAL WATER OF THE

GULF THREW OFF A DELICATE

BALANCE.

LOCAL VOLUNTEERS FOUND THE

REMAINS OF MORE THAN 150

DOLPHINS AND 23 TURTLES.

SCIENTISTS ON WLOX'S NEWSCAST IN

BILOXI, MISSISSIPPI, BLAMED THE

LOSS OF MARINE LIFE ON THE

INFLUX OF FRESH WATER.

>> ADDITIONAL NON-SALT WATER

THAT COMES IN DECREASES THE

SALINITY IN THEIR ENVIRONMENT,

AND THAT CAUSES SOME-- SOME

MAJOR PROBLEMS WITH THESE GUYS.

>> TWO PARTS PER 1,000 SALINITY

IN WATER.

YOU CAN STICK YOUR FINGER IN IT,

AND IT TASTES LIKE FRESH WATER.

THESE ANIMALS ARE JUST NOT MADE

FOR THAT KIND OF FRESH WATER,

THAT KIND OF FLEXIBILITY.

FOR US, IT WAS 100% MORTALITY.

SO, WE LOST PROBABLY 14,000

OYSTERS IN THAT EVENT.

>> Reporter: AUTHOR AND CHEF

MELISSA MARTIN SEES THE CHANGES

SHOWING UP IN HER KITCHEN.

SHE'S THE FOUNDER OF THE

MOSQUITO SUPPER CLUB IN NEW

ORLEANS.

>> I CREATED THESE TABLES SO WE

COULD START A CONVERSATION ABOUT

SOUTH LOUISIANA, AND TALK ABOUT

SUSTAINABILITY AND FOOD AND LIFE

AND THE ENVIRONMENT.

WHAT WE DO HERE IS TRY TO GIVE

PEOPLE A MEAL THAT THEY WOULD

HAVE AT MY GRANDMOTHER'S HOUSE

OR MY MOM'S HOUSE, SERVING THE

FOOD THAT I GREW UP EATING.

I GET WORRIED, WHEN I PEER INTO

THE FUTURE, ABOUT RUNNING A

RESTAURANT.

I WON'T BE RUNNING A RESTAURANT

BASED ON SEAFOOD FROM OTHER

PLACES.

I WILL ALWAYS BE RUNNING A

RESTAURANT BASED ON WHAT I COULD

GET HERE.

AND THAT MAY MEAN THAT ONE DAY

THAT I'M NOT A SEAFOOD

RESTAURANT.

AND THAT'S A REALLY SAD THOUGHT,

BUT THAT'S KIND OF THE REALITY

OF WHERE WE ARE.

>> Reporter: MARTIN'S KITCHEN

HASN'T SUFFERED SOLELY FROM THE

INTRUSION OF FRESH WATER INTO

SALT WATER.

SALT WATER MOVING INTO FRESH HAS

BEEN AN EVEN BIGGER PROBLEM.

THE NUMEROUS OIL AND GAS

PRODUCTION FACILITIES IN THE

AREA UTILIZE A MAZE OF MANMADE

CHANNELS, ALLOWING SALT WATER TO

INVADE MARSHLANDS, CAUSING

EROSION AND DESTROYING

SEAFOOD-RICH HABITAT.

>> TERREBONNE PARISH USED TO BE

ONE OF THE HIGHEST OYSTER-

PRODUCING PLACES IN THE STATE.

BUT ONCE THE SALTWATER INTRUSION

STARTED HAPPENING BECAUSE OF THE

OIL FIELDS, WE LOST PRETTY MUCH,

YOU KNOW, ALL OF OUR OYSTER

BEDS.

THE AMOUNT OF SHRIMP THAT WE

HAVE HAS CHANGED BECAUSE WE JUST

DON'T HAVE ESTUARIES FOR THEM TO

LIVE IN.

YOU KNOW, THEY'RE JUST BEING

EATEN AWAY BY SALT WATER.

YOU KNOW, IT'S A HUGE RED FLAG

THAT WE'VE GOT SOME MAJOR THINGS

HAPPENING.

>> FOR US, ENVIRONMENTALLY, OUR

MARKERS HAVE BECOME SOME OF

THESE BIG DISASTERS.

YOU KNOW, A HUGE HURRICANE.

A HUGE OIL SPILL.

A HUGE FLOOD SITUATION.

I WOULD HATE TO THINK THAT

THAT'S THE ONLY MEASURES THAT WE

HAVE OF OUR TIME, YOU KNOW, BUT

IT SEEMS LIKE RIGHT NOW THOSE

ARE THE MEASURES OF OUR TIME.

WE'RE GOING TO HAVE TO DO WHAT

FARMERS ALL OVER AMERICA DO--

JUST TRY TO INSURE IF WE CAN

AND DO A LOT OF PRAYER, I GUESS,

BECAUSE WE'VE GOT NO CONTROL

OVER SOME OF THOSE THINGS.

>> Reporter: AERIAL PHOTOGRAPHER

BEN DEPP, SEEN IN PBS' 2019

SERIES "RIVERS OF LIFE," IS ONE

OF MANY ARTISTS IN NEW ORLEANS

FOR WHOM THE DELTA IS A CORE

INSPIRATION.

BUT IN EXPLORING THE ICONIC

LANDSCAPE, HE KNOWS HE'S

DOCUMENTING A DISAPPEARING

WORLD.

>> EVERYWHERE YOU LOOK, YOU SEE

THE THOUSANDS OF MILES OF CANALS

CUT THROUGH THE WETLANDS, WHICH

CAUSED SALTWATER INTRUSION,

WHICH KILLED THE VEGETATION AND

CAUSED THE GROUND TO ERODE.

YOU CAN SEE THE MARSH JUST

FRAGMENTING APART.

>> Reporter: SOME CHANNELS

PRE-DATE THOSE CREATED BY THE

OIL INDUSTRY.

THEY WERE MADE TO TRANSPORT

TREES DURING A SURGE IN COASTAL

LOGGING IN THE LATE 1800s AND

EARLY 1900s, WHEN LOUISIANA WAS

THE NATION'S LARGEST PRODUCER OF

TIMBER.

>> THIS PLACE USED TO BE A

THRIVING ECOSYSTEM MOSTLY

FORESTED WITH CYPRESS AND

TUPELO, AND JUST THIS

EXPANSIVE, WET HARDWOOD FOREST

FULL OF ALLIGATORS AND FISH.

SOME AREAS HERE ARE STILL

INCREDIBLE, BUT IT'S KIND OF

JUST THE EDGES OF WHAT THIS

PLACE USED TO BE.

>> Reporter: THE BALD CYPRESS

CAN GROW TO 1,700 YEARS OLD ON

THIS COAST.

SOME SCIENTISTS ESTIMATE IT

WOULD REQUIRE ABOUT THAT AMOUNT

OF TIME TO UNDO HUMANS' IMPACT

ON THE MISSISSIPPI DELTA.

IN THE MEANTIME, DEBBIE FOUNTAIN

OFFERS HER OWN PLAN.

>> WE ALL HAVE TO BE BETTER

STEWARDS OF WHAT WE USE AND HOW

WE BEHAVE AND WHAT WE DO.

ALL OF US HAVE TO BECOME BETTER

STEWARDS.
