GUARDIANS OF THE WILD

0:04
Every wild animal deserves our stewardship.

0:07
From the endangered golden lion tamarind to the threatened American bison, many iconic animal species have captured our imaginations.

0:16
Their conservation stories symbolize our responsibility to protect the wild places and animals of the world, and today we're highlighting a few of our favorites.

0:29
Sea turtles are one of the most beloved animals on Earth.

0:33
These long distance swimmers migrate thousands of miles across the world's oceans.

0:38
Thanks to global cooperation and awareness, sea turtles are protected, but all 7 species are threatened and some are critically endangered.

0:48
Turtles a conservation because they are threatened by pollution, they're threatened by climate change, they're also threatened by fishing and bycatch.

0:59
Today, I'm in the Bahamas to take part in a sea turtle conservation project.

1:07
Kristen, this is really cool.

1:08
All these sea turtles behind us.

1:10
Can you tell me what is going on right here?

1:13
They're between three and four years old.

1:15
So we've had them for that period of time with the intention of releasing them back into the wild.

1:19
How many have been released so far?

1:21
I want to stay over 7,000.

1:24
So somewhere around that.

1:25
Yeah.

1:25
Oh, my gosh.

1:26
You guys must be really proud of that.

1:28
We are.

1:29
We want to give back to the environment.

1:30
You know, we're here.

1:31
We're benefiting from it, and we want to be able to contribute to that.

1:34
So we we take joy and giving back.

1:38
The conservation staff chose a suitable candidate for release.

1:41
Hi.

1:42
I think this one's ready to go explore the ocean.

1:46
What do you say, bud?

1:48
All right, right in here.

1:50
Here we go, buddy.

1:52
Then we brought the young green sea turtle to the resort's fish hospital.

1:56
I'll help on the side.

1:58
OK.

1:59
This is exactly 40 centimeters.

2:02
Nice.

2:03
Recorded its measurements and weight.

2:07
Precious cargo right here.

2:09
Got it.

2:09
Got it.

2:12
And drove out along the coast, 20 minutes away from Atlantis.

2:17
The release site is full of lush seagrass beds.

2:20
A perfect grazing area for this endangered turtle species.

2:25
Your moment.

2:25
Here we go And just let it.

2:28
Let it go.

2:29
Yeah, just let it go a moment.

2:31
Bye.

2:32
This green sea turtle descending gently into its new home is living proof of the conservation work being done by Kristen and the team at Atlantis.

2:46
Yeah, awesome.

2:54
Sea turtles are ancient and iconic animals that must be protected.

2:59
Their species struggle for survival has come to represent the fate of Wildlife Conservation itself.

3:10
The mighty polar bear is a conservation icon that's become an ambassador for all forms of wildlife and for the larger cause of environmental protection.

3:20
I'm at the Columbus Zoo and Aquarium to study polar bears and learn about the challenges they face in the wild.

3:28
This is an incredible habitat.

3:29
Yeah.

3:30
I can't imagine anybody having been in the water before having polar bears swimming over their heads.

3:36
Yeah, there are two polar bears here at the Columbus Zoo, a female named Aurora and Lee swimming above me.

3:44
What is he doing?

3:44
Most people picture polar bears on the top of the ice.

3:48
They are super good swimmers.

3:50
Lee is our male.

3:51
He is actually diving for his favorite treat which is yogurt covered raisins.

3:57
Wild polar bears live in Arctic regions like Canada, Alaska, Russia, Greenland and Norway.

4:03
They spend most of their time on sea ice that floats on the surface of polar oceans and seas.

4:12
They are uniquely adapted to be able to live on the ice and swim in the Arctic Ocean.

4:16
Their paws and their paw pads are basically paddles.

4:21
They're giant.

4:22
They have a lot of surface area, they're webbed, and although they are great swimmers, they're not built for marathon distance swimming.

4:30
They are not seals, they're bears.

4:32
The changing of the sea ice when it forms, how much ice is forming, is making them have to swim super long distances to find food.

4:43
Polar bears are expert predators.

4:45
They rely on a technique called still hunting to ambush their primary prey, ring seals.

4:52
They lie in wait near the seals, breathing holes, ready to strike when a seal surfaces for a breath of air.

5:00
But heat trapping gases such as methane and carbon dioxide released by burning fossil fuels have warmed the Arctic by almost 6°F and rising more often than not.

5:12
The sea ice is now forming later and melting earlier.

5:16
Climate change is shrinking the bears icy hunting grounds and threatening their very survival.

5:23
Warmer climates, less ice, shorter hunting season.

5:26
Yeah, it takes a lot of energy to be a polar bear.

5:30
To survive in the Arctic.

5:31
You need to have a really thick layer of fat on your body.

5:35
So their biggest threat is climate change, and they really depend on that ice.

5:40
The growing climate threats confronting polar bears affect all of us as well.

5:45
These iconic creatures speak to us with a powerful voice, a cry for protection and stewardship for our Wild Kingdom.

Did you know animals have their own superheroes? They’re called guardians of the wild, aka the folks working in wildlife conservation.

We spotlight icons of conservation who work tirelessly to protect wildlife. In the Bahamas, Dr. Rae collaborates with a team of conservationists to release a young green sea turtle back to its ocean habitat. Then, Peter gets an up-close look at polar bears at the Columbus Zoo and Aquarium and hears about the challenges they face to survive in the wild. In Panama, Dr. Rae joins locals at a festival to celebrate the country’s national bird — the harpy eagle — and the cultural significance of this powerful predator protecting the rainforest. Finally, Peter dives deep with a research team in Mexico to study the impact of tourists who flock to the area to swim with massive whale sharks.

Go behind the scenes of filming whale sharks and polar bears. Then, learn what it was like to film harpy eagles in Panama.
