WE ARE ALL PART OF TEAM EARTH.

THIS IS THE ASIA THAT MOST OF US ENVISION -- CHAOTIC, BUSTLING, AND URBAN.

BUT BEYOND THE CROWDED CITIES OF NEPAL AND INDIA LIE PRECIOUS REMNANTS OF WILD ASIA WHERE RHINOS, TIGERS, AND BEARS STILL ROAM FREE.

I'M ART WOLFE.

THIS IS "TRAVELS TO THE EDGE."

FROM HERE IN KATHMANDU, THE GREAT HIMALAYAS RISE NORTH INTO THE CLOUDS.

BUT ON THIS TRIP, WE'RE SKIPPING THE BIG MOUNTAINS AND HEADING INTO THE LOWLANDS.

FIRST TO NEPAL'S CHITWAN NATIONAL PARK, AND THEN INTO INDIA IN SEARCH OF ASIA'S MOST IMPRESSIVE WILDLIFE.

AS DAWN BREAKS OVER THE RAPTI RIVER, I'M MAKING MY WAY TOWARDS ROYAL CHITWAN NATIONAL PARK.

IT'S A PEACEFUL SCENE AS THESE LOCAL THARU PEOPLE MAKE THEIR WAY TOWARDS THE SAL FOREST TO GATHER FIREWOOD.

NAMASTE!

NAMASTE!

CHITWAN IS ONE OF THE FEW REMAINING WILD AREAS THAT ONCE EXTENDED IN A WIDE SWATH ALONG THE FOOTHILLS OF INDIA AND NEPAL.

ITS RIVERS AND FORESTS ARE RICH WITH WILDLIFE, INCLUDING BIRDS, RHINO, AND REPTILES.

THIS IS THE ANIMAL I WAS HOPING TO SEE IN THE WILD.

THIS IS KNOWN AS A GHARIAL.

IT'S RELATIVELY HARMLESS TO HUMANS BECAUSE OF THE NARROWNESS OF THE SNOUT.

JUST A VERY UNIQUE ANIMAL.

I'VE NEVER SEEN IT BEFORE.

I'VE SEEN A LOT OF CAIMAN AND CROCODILES AND ALLIGATORS, BUT NEVER -- OH, AND IT'S COMING RIGHT TOWARDS ME.

THAT WAS EXCITING.

CROCODILE.

LET'S GO CLOSER.

THIS HAS GOT THE POTENTIAL FOR A VERY NICE IMAGE.

LET'S SEE WHAT I CAN DO WITH THIS.

I NEVER CAN GET ENOUGH SHOTS OF THESE REPTILES.

THEY'RE SO PRIMORDIAL, THEY'RE SO ANCIENT.

THEY'RE SO UNLIKE ANY OTHER ANIMAL.

AH.

GO UP, OKAY.

GO UP.

UP, UP, UP.

OKAY, OKAY.

IT WASN'T GLAMOROUS, BUT... SEE?

EASY.

OH, NOW, YOU DID IT SO SMOOTHLY.

I'VE RECRUITED DHAN BAHADUR TAMANG, A LOCAL NATURALIST, TO GUIDE ME THROUGH THE PARK.

GOING BY ELEPHANT GIVE US GREATER ACCESS, ALLOWING US TO EXPLORE THE FOREST WITHOUT DISTURBING OTHER WILDLIFE.

WE'RE MOVING THROUGH CHITWAN NATIONAL PARK, LOOKING FOR THE WORLD'S LARGEST RHINO, THE ONE-HORNED INDIAN RHINO.

Tamang: WE'RE GOING TO FOLLOW THE TRACKS.

CAN SEE, ACTUALLY, HERE, LOOK.

OH, YEAH.

YOU SEE THAT?

YEP.

THEY HAVE THREE TOE.

HUNTING FOR A RHINO.

WHO WOULD HAVE THOUGHT?

THIS IS COOL.

AND HE COULD BE JUST OUT HERE IN THE GRASS... OR NOT.

IT COULD BE.

IT COULD BE HERE, YES.

THAT'S THE RHINO THERE.

LET'S GO, GO, GO.

OVER THERE, OVER THERE.

Wolfe: HOW MANY RHINOS ARE IN THE PARK?

WE HAVE ABOUT 375 RHINOS IN THE WHOLE PARK.

THIS IS REALLY GOOD HABITAT TO THE RHINOS.

Wolfe: I REMEMBER COMING HERE 20 YEARS AGO, AND THERE WEREN'T THAT MANY RHINOS.

Tamang: THAT TIME, THERE WAS VERY LOW NUMBERS, LIKE ABOUT 80 OR SOMETHING LEFT.

SO IT'S GETTING BETTER NOW.

RHINO HORN'S ACTUALLY MADE BY THE HAIR.

THE HORN IS REALLY DENSE, HARD HAIR?

VERY HARD HAIR, YES.

IT'S NOT BONE AT ALL.

YOU SEE THE ARMOR PLATE THERE.

LOOK LIKE VERY STRONG NOW, BUT NOW IS VERY SOFT.

WHEN THE SKIN IS DRY, IT'S LIKE BULLET-PROOF.

THESE ARE REALLY FAST ANIMALS.

THEY ARE.

THEY RUN LIKE 40 KILOMETERS PER HOUR IF THEY WANTED.

BUT NOT FOR DISTANCE.

FOR A SHORT DISTANCE, THAT FAST THEY RUN.

YOU HAVE TO BE CAREFUL WHEN YOU ARE WALKING.

OH!

KEEP GOING, KEEP GOING.

THIS IS REALLY NICE.

MOTHER WITH ITS CALF, THE CALF IS RUNNING AROUND.

SO LET'S JUST GO A LITTLE FURTHER UP HERE.

NOT TOO CLOSE.

OH, STOP, STOP, STOP.

THAT WAS THE SHOT I WAS HOPING TO GET.

PERFECT LIGHT, JUST THE LAST FEW MOMENTS OF THE DAY WHEN THE LIGHT IS SUFFICIENT ENOUGH TO STOP THE MOTION.

REALLY NICE.

THEY'RE ABOUT TO GO OFF INTO SOME REALLY TALL GRASS RIGHT NOW, AND I THINK THAT'S IT FOR THE DAY.

THESE MAHOUTS ARE TAKING THESE ELEPHANTS IN FOR A BATH.

THE ELEPHANTS HAVE BEEN WORKING IN CHITWAN ALL MORNING LONG, AND NOW THEY LOVE NOTHING MORE THAN TO GET INTO THE WATER.

OH, LOOK AT THAT.

OH, NICE MOMENT.

OH!

IT FEELS SO GOOD.

CLEARLY THE MAHOUT AND THE ELEPHANT HAVE CREATED A VERY STRONG BOND OF TRUST, AND NOW, LOOK AT THIS MAHOUT.

HE'S CLEANING THE STONES OUT OF THE ELEPHANT'S FEET, AND HE'S JUST GENTLY LETTING THE WATER CREST HIS BODY.

IT'S JUST REALLY A NICE, TENDER MOMENT.

IT'S JUST AMAZING CONTROL AND TRUST BETWEEN MAN AND ELEPHANT HERE.

THEY LOOK LIKE BIG TEDDY BEARS.

NICE -- POWERFUL ANIMALS.

I JUST LOVE THIS VIEW WHEN THE ELEPHANT GIVES THIS GUY A BATH.

LET'S GO UP THIS ROAD.

DHAN BELIEVES THERE'S SLOTH BEARS IN THIS PARTICULAR FOREST.

SLOTH BEARS ARE REALLY FEROCIOUS AND VERY SECRETIVE ANIMALS.

JUST KEEP GOING, KEEP GOING.

A SLOTH BEAR WITH TWO BABIES ON THE BACK AND ONE ON THE GROUND.

THE BEARS ARE VERY UNIQUE IN THE BEAR WORLD IN THEIR ABILITY TO CARRY THEIR BABIES ON THEIR BACK.

LET'S GO UP THE ROAD.

OKAY, STOP.

I CAN'T BELIEVE THE BABIES ARE STILL ON HER.

LET ME SEE IF I GOT THAT.

YEAH, LOOK AT THAT PICTURE.

I'VE GOT -- YOU CAN SEE THE TWO BABIES, BUT NO HEAD ON THE MOTHER.

ALMOST A GOOD SHOT.

ALMOST A GOOD SHOT.

SOMETIMES YOU GET IT, SOMETIMES YOU DON'T.

TOMORROW, WE'LL TRY AGAIN.

THAT'S IT.

ALL RIGHT, LET'S GO HOME.

THIS IS REALLY NICE.

MOTHER AND ITS TWO-MONTH-OLD CALF RIGHT OUT IN WARM, EARLY MORNING LIGHT.

HELLO, AND THE BABY JUST RUNS THROUGH THE MOTHER'S LEGS FOR SECURITY.

SO IT GOES OUT 10, 15, 20 FEET AWAY FROM THE MOTHER, AND THEN IT COMES RIGHT BACK, AND EVERY TIME IT COMES BACK THERE'S SOME SORT OF CONNECTION WITH THE MOTHER.

THE BABY'S PUTTING ITS NOSE UP.

IT'S GOT ITS EYES LOOKING AT US.

IT TWEAKS ITS EARS, AND IT'S ALMOST GOT THIS GOOFY EXPRESSION, WHICH IS REALLY NICE TO CAPTURE ON SUCH AN ENORMOUS ANIMAL.

Tamang: SEE THE BABY, IT'S LOOKING AT US, AND IT GO TO THE MOTHER TO TOUCH IT AGAIN AND COME BACK, YOU KNOW?

Wolfe: IT'S JUST FASCINATING TO ME HOW ADORABLE A BABY RHINO CAN BE.

THESE ARE ANIMALS THAT HAVE BEEN HAMMERED IN THE PAST BY POACHING AND BY TROPHY HUNTING, AND IT'S GREAT TO SEE SO MANY OF THEM GIVING BIRTH TO BABIES AND RELAXED AND IN THEIR NATURAL HABITAT, WHICH IS EXACTLY THE WAY ONE WOULD HOPE TO SEE THEM.

YOU SAW HIM?

IT'S BETTER THAT WE JUST KIND OF LEAVE HIM.

[ LAUGHS ] IT'S SO AMAZING THAT IT WAS HERE.

[ TAMANG CALLING ] Wolfe: WILL IT BE OKAY IF I GET OUT?

YEAH, WE'RE NOT GOING TOO FAR.

WE'LL GO OVER HERE, BUT WATCH THE RHINO.

IF RHINO COME TOWARD US, LEAVE YOUR CAMERA THERE, WHATEVER YOU HAVE, AND WE'LL JUST RUN AT THE CAR.

THESE ANIMALS ARE SHORT-TEMPERED AND FAST-MOVING.

NOW WE'RE GETTING TO THE POINT WHERE WE ARE EXPOSED.

I'VE BEEN CHARGED BEFORE, AND WE DON'T WANT THAT, SO LET'S JUST BRING THE CAR DOWN.

IT'S THERE, IT'S THERE.

IT'S JUST IN THERE.

IT'S THERE.

YOU CAN SEE THE FACE.

THAT'S A BIG BULL.

BIG BULL, YES, BIG MALE.

BIG DOMINANT MALE OF THIS AREA.

AND HE'S GOT A BIG SCAR ON HIS SHOULDER.

HE'D BEEN FIGHTING WITH OTHER MALE.

SO HOW FAST CAN YOU RUN?

NOT VERY FAST, SIR.

NOT VERY FAST.

I CAN RUN UP TO THE TREE.

LET'S GO DOWN THE ROAD AND SEE WHAT WE CAN FIND.

OKAY, SIR.

GO THIS WAY.

LEAVE RHINO IN THE GRASSLAND.

LET'S SEE IF WE CAN GET A LITTLE CLOSER BY THE CAR.

RIGHT HERE.

RIGHT THERE.

THIS IS REALLY CLOSE.

THIS IS THE BEST VIEW I'VE SEEN, ESPECIALLY OF A MALE, AND HE IS CHECKING US OUT RIGHT NOW.

IT'S REALLY AMAZING WHEN IT LIFTS ITS HEAD AND SUDDENLY STARES RIGHT AT YOU.

IT GOES INSTANTLY FROM AN ANIMAL GRAZING IN THE GRASS TO BEING THIS POWERFUL PRESENCE.

WE'VE LEFT THE SAL FOREST OF NEPAL AND TRAVELED FURTHER SOUTH TO THE GREEN HEART OF INDIA AND THE JUNGLES OF BANDHAVGARH.

NOT ONLY IS BANDHAVGARH RICH WITH WILDLIFE, IT'S A SANCTUARY FOR ASIA'S LAST REMAINING BENGAL TIGERS.

FINDING A TIGER IN A JUNGLE IS LIKE A NEEDLE IN A HAYSTACK.

THERE'S A TIGER RIGHT UP HERE.

IT'S JUST MOVING THROUGH THE TREES.

OH, THERE'S TWO TIGERS RIGHT HERE.

TIGERS!

WILD BENGAL TIGERS IN INDIA.

AH, FANTASTIC.

RIGHT THERE.

THERE'S A TIGER JUST LAYING DOWN.

I'VE GOT A PARTIAL VIEW.

IT'S REALLY DIFFICULT TO GET A GOOD VIEW.

THIS BEAUTIFUL BENGAL FEMALE IS SITTING BEHIND SOME VERY FINE-LINED BAMBOO, AND SO I'M GOING TO SHOOT THIS ANIMAL WITHIN THE CONTEXT OF ITS ENVIRONMENT.

THE BAMBOO IS EVERY BIT AS IMPORTANT AS THE CAT ITSELF.

STAY, STAY, STAY.

[ TAMANG SHOUTING ] THIS IS FANTASTIC.

LOOK, HE'S GOING TO GET UP.. THAT'S INCREDIBLE.

OH, LAY DOWN AND LOOK AT US.

OH!

SO BEAUTIFUL ON THIS LOG.

I LOVE THE NATURAL, RELAXED BEHAVIOR.

WHEN A TIGER LOOKS INTO YOUR EYES, YOU NEVER FORGET THE MOMENT.

WOW, WHAT A POWERFUL CAT.

JUST BEAUTIFUL.

THIS TIGER KEEPS WANTING TO CHARGE THE ELEPHANT.

[ TAMANG SHOUTING ] JUST TO SEE THE POWER AND THE STEALTH OF THESE ANIMALS IS AMAZING.

EVERYWHERE THIS CAT GOES, HE LOOKS GREAT.

LOOK AT THE EYE SPOTS BEHIND THE EARS.

THEY'RE MEANT TO REALLY KEEP THEM FROM BEING ATTACKED FROM BEHIND BY OTHER ANIMALS, LIKE OTHER TIGERS, AND IT JUST LOOKS LIKE HE'S STARING RIGHT BACK AT US.

WE'RE IN THE SECOND MOST POPULATED COUNTRY IN THE WORLD, AND IT'S JUST AMAZING AND ITS A COMFORT TO ME TO KNOW THAT THERE ARE NATURAL ENVIRONMENTS WHERE THE TIGER STILL THRIVES.

FOR MY LAST EXCURSION INTO THE FOREST, I'VE BEEN LUCKY ENOUGH TO BE JOINED BY BELINDA WRIGHT, THE WORLD'S FOREMOST AUTHORITY ON BENGAL TIGERS, AND A PASSIONATE ADVOCATE FOR THEIR PRESERVATION.

Wright: THIS IS PRIME TIGER HABITAT, BUT THEY ALSO LIVE IN MANGROVES, THEY LIVE IN GRASSLANDS, AND THEY'RE VERY ADAPTABLE.

THIS PARTICULAR AREA, THIS HAS VERY HIGH DENSITY OF TIGERS.

THERE'S PROBABLY EIGHT OR NINE TIGRESSES WITH CUBS.

PROBABLY THE EASIEST WAY TO FIND A TIGER IS TO LISTEN, IS TO BE SORT OF QUIET AND LISTEN TO ALARM CALLS, BECAUSE A PREDATOR LIKE THAT JUST CANNOT WANDER AROUND A JUNGLE LIKE THIS WITHOUT SOMEBODY GIVING IT AWAY.

NOW I'M LISTENING.

[ ANIMAL CALLING ] OH, THERE'S A TIGER.

STOP, STOP, STOP, STOP.

THAT'S A NICE SHOT.

ISN'T THAT LOVELY?

YES.

THERE'S A THIRD CUB SOMEWHERE AROUND THE PLACE.

CUBS WILL STAY WITH THEIR MOTHER FOR A COUPLE OF YEARS.

YEAH.

AND SHE'S TEACHING THEM HOW TO HUNT.

SHE TEACHES THEM EVERYTHING.

HOW OFTEN DOES SHE HAVE TO TAKE AN ANIMAL?

THESE CUBS ARE LARGE, SO SHE WOULD BE EVERY THREE DAYS, FOUR DAYS, SHE'LL HAVE TO KILL TO PROVIDE FOR THEM.

SHE'S A BUSY LADY.

TIGERS OCCUR IN SMALL NUMBERS ALL OVER THE PLACE, BUT ITS ONLY INDIA THAT HAS A POPULATION OF OVER 500 WILD TIGERS.

IT'S FAIRLY MIRACULOUS THAT INDIA STILL HAS TIGERS AT ALL.

I MEAN, MOST COUNTRIES HAVE LOST THEIR BIG PREDATORS.

I NEVER DREAMED THAT I'D EVER PHOTOGRAPH A WILD TIGER, AND IT WAS JUST BEYOND MY WILDEST DREAMS AS A YOUNG BOY GROWING UP IN SEATTLE, AND HERE YOU GREW UP IN CALCUTTA WITH A TIGER CUB IN YOUR HOUSE.

YES, MY WHOLE LIFE HAS BEEN ABOUT TIGERS.

I THINK I'VE BECOME SUCH A TIGER ACTIVIST, I WORRY ABOUT THE CUBS' FUTURE.

WHERE ARE THEY GOING TO GO?

THERE ISN'T EXTRA SPACE NOW FOR ALL THESE CUBS.

IT IS SUCH AN IMPORTANT FLAGSHIP SPECIES.

BY SAVING THE KEY PREDATOR, YOU'RE SAVING EVERYTHING ELSE THAT'S IN ITS KINGDOM, AND AS SOON AS YOU LOSE AN ANIMAL LIKE THAT, THEN YOU ALSO LOSE THE REASON FOR PROTECTING THESE VITALLY IMPORTANT HABITATS.

WHAT I THINK THAT INDIA MUST AIM FOR IS KEEPING OUR -- CERTAINLY -- OUR IMPORTANT PROTECTED AREAS INTACT, MAKING THEM COMPLETELY INVIOLATE, SO THAT THEY'RE UNTOUCHABLE FOR NOW AND FOREVER.

TIGERS ARE MY OBSESSION AND MY SORT OF REASON FOR LIVING.

TILL THE DAY I DIE, I'LL FIGHT FOR THE TIGER.

Wolfe: THE MAGNIFICENT TIGER HAS LONG BEEN A SYMBOL OF WILD INDIA, BUT TODAY, IT'S MORE THAN THAT.

IT'S A SYMBOL OF THE NATURAL WORLD UNDER PRESSURE.
