NARRATOR: There are some places where a day at the beach...
Official YIFY movies site: YTS.MX
can turn into an unexpected encounter with the ocean's top predator.
(gurgling)
(dramatic music)
WOMAN: There's sharks out here? Right now?
SURFER: Look at that. I'm shaking like a leaf.
DR. CHRIS LOWE: We're seeing things that I just never expected
-I would see. -BOYS: Oh my god!
It's a different ocean.
MAN: This is Jaws unfolding.
(shouts)
(splashing, gurgling)
(gurgling)
(tense music)
NARRATOR: Santa Barbara, California.
The golden coast. Home to world-famous beaches.
(splashing)
And now, large numbers of great white sharks.
SURFER: Oh my god, right under the board.
(dramatic music)
LESTER HOLT: Great white sharks getting way too close up and down the coast.
NARRATOR: The surge in sightings is hitting the headlines.
KAYAKER: It was like a foot from my face, grabbing onto the kayak right here.
SURFER: Oh my gosh, dude.
NARRATOR: And with shark numbers still going up...
(rumbling)
...a team of scientists have come to investigate.
Chris Lowe's SharkLab have some big questions to answer.
LOWE: We have lots of sharks. We have lots of people.
The public are wondering what's going on,
what are the sharks doing here, and is it safe
for my kids to swim or surf in this beach?
(gurgling)
NARRATOR: With public safety at stake...
they must attempt an ambitious new scientific experiment.
(rock music)
(boats roaring)
One day, three miles of Californian coast,
and seven boats.
(rumbling)
This is a great white stakeout.
The aim?
Find out how many sharks cruise Santa Barbara's waters
and understand what's bringing them here.
Crucial data that could change how sharks and people share the water forever.
The stage has been set for today,
and now I'm just really excited to finally get out there and see what we find.
PATRICK REX: This has, to my knowledge, never been done before.
-NARRATOR: Joining the mission... -ANDY CASAGRANDE: SharkLab, do you copy?
NARRATOR: ...is filmmaker Andy Casagrande.
CASAGRANDE: While the SharkLab is in charge of the science,
I'll be filming the entire event. The science, the people, and the sharks.
NARRATOR: To stay on top of the action,
Andy has brought the ultimate in nonstop aerial surveillance.
CASAGRANDE: Drones are some of the coolest technology on the planet,
but you gotta land them to change batteries. But, this drone is different.
I'm powering this drone from the boat from a tether
which is going to allow me to fly essentially nonstop.
Just like great white sharks, they never stop swimming,
and this drone's never going to stop flying.
It's the perfect tool for the stakeout.
(click)
NARRATOR: Drones will be key to the success of today's mission.
They can search vast areas of water at speed.
And provide an incredible new perspective on these elusive predators.
(dramatic music)
(splashing)
(gurgling)
Great whites grow up to 20 feet long.
And can pack over 5,000 pounds of muscle.
Yet despite their size, they often go unnoticed.
A type of camouflage known as counter-shading
gives these sharks the predatory edge.
They're dark on top, but pale underneath.
So, under water,
they blend into the background, whether seen from above...
or below.
But all that changes...
from the air.
CASAGRANDE: Alright! Here we go! Tethered drone taking off.
-(beep, whirring) -(beeping)
NARRATOR: From high in the sky, a shark's camouflage can't hide them,
and their cover will be blown.
CASAGRANDE: Let's try to find some sharks here.
(whirring)
NARRATOR: The best view of what's below the surface
comes from high above.
Andy's drone scans from the sky.
-(laughter) -And while down at water level,
it looks like every other day at the beach...
-(waves crashing) -(chatter)
the view from above...
Whoa, whoa, right there!
NARRATOR: ...reveals a very different story.
A drone's-eye view detects an unmistakable silhouette.
Now, you see it.
Now, you don't.
CASAGRANDE: It's pretty incredible. There's sharks everywhere.
Literally right under the boards of these people.
Right under their noses, and they don't even see it!
NARRATOR: Down at water-level,
glare and reflections can easily distract,
hiding what looks obvious from high above.
(dramatic music)
CASAGRANDE: I got a lot of sharks in the area. This is incredible.
NARRATOR: It looks too close for comfort, but are people in danger?
(gurgling)
Despite Santa Barbara's increase in shark sightings,
there hasn't been a fatal shark bite here in almost a decade.
A stat that today's survey will help unpack.
(motors running)
-CASAGRANDE: Synchronize watches. -(watches beeping)
Alright, great white stakeout, here we go!
(whirring)
CREW MEMBER: Alright, and three, two, one, here we go.
(whirring)
(radio beep)
LOWE: The last sightings have been around 175 meters off the beach.
(radio beep)
NARRATOR: Where the sharks gather changes day to day.
(whirring)
-Drones help the team search the area. -CASAGRANDE: So far, I see a lot of kelp.
They can travel pretty far in a short period of time.
(whirring)
-Chris, how's it looking out there? -(walkie-talkie beep)
LOWE: So far Pat's covered a lot of water
and hasn't seen anything yet. How about you?
CASAGRANDE: I got nothing yet. I'll keep flying,
and if I see anything, I'll let you know.
LOWE: Standing by.
(whirring)
Hey, Patrick, you're almost out of juice.
Maybe it's time to come back and re-battery?
-REX: Roger that. -(radio beep)
Got the birds coming in.
NARRATOR: Leading the SharkLab drone patrol is Patrick Rex.
(drone whirring)
REX: Nice work, gentlemen.
CASAGRANDE: I love drones. Essentially a camera you can put anywhere,
and it's remote control.
But, for science, what exactly are you using these drones for?
Yeah, I mean, it's actually changed the game of ecology.
We can survey quite a large area in a really short amount of time.
So, what I do is I fly about a kilometer away,
following the shoreline,
looking for sharks and people in the same water at the same time.
CASAGRANDE: Sharks and people, so you're going for behavior?
REX: Yeah, exactly.
(waves crashing)
NARRATOR: The team wants to know...
how many sharks are out there.
So, another fleet of drones will run a head count.
(whirring)
Every shark passing through the football field-sized survey area
will be filmed and logged.
(beeping)
But the drones have their limits.
LOWE: The water is murky, and the shark is literally two feet
below the surface. You can't see it.
(tense music)
NARRATOR: The only way to confirm how many sharks are really out there
is to get above... and beneath the surface.
(boat roaring)
Andy is about to witness the ultimate chase.
CASAGRANDE: Coming right across the bow.
(dramatic music)
CASAGRANDE: We're trying to determine what happens
when a beach full of people meet an ocean full of sharks.
(gurgling)
SURFER: Oh my god. Right under the board.
NARRATOR: To understand Santa Barbara's surge in shark sightings,
SharkLab needs to know what numbers they're dealing with.
(beeping)
For the very first time,
they're combining two different techniques.
(whirring)
Drones count sharks from above...
while the next phase of the mission will count them from below.
Fitting sharks with tags.
-(clicking) -(indistinct chatter)
Time for Andy and the team to stalk the stalker.
Great whites are apex predators that hunt using stealth and speed.
They aren't used to being the ones being tailed.
CASAGRANDE: Alright. We got a diver in the water.
(tense music)
The entire team's deployed.
We got two drones up in the sky, three boats,
jet skis.
If the sharks are here, we're going to find them.
(boats rumbling)
Looks like we got one out here about 100 meters.
NARRATOR: Leading the tagging operation is Emily Spurgeon.
SPURGEON: We had to sneak up on these sharks
while they're swimming at the surface and use a pole spear or a harpoon.
We'll just jab the tag right at the dorsal fin
and give them a new bit of jewelry.
-(click) -CREW MEMBER: Yes!
SPURGEON: We essentially are doing a dance with the sharks.
(rock music)
We call it the do-si-do.
We'll just circle dance with these sharks.
(indistinct chatter)
-(click) -(splash)
(beeping)
NARRATOR: Each tag gives off a unique sound.
It can't be heard by sharks or people, but can be picked up
by the 27 underwater receivers rigged along this coast.
LOWE: Every time a shark swims within 300 yards of one of those receivers,
the receiver will log the time, the date, and the ID number.
So think of it like E-ZPass on the toll road.
-CREW MEMBER: Woo-hoo! -(click)
Perfect!
NARRATOR: Problem is to get the tracking data,
you need to go fetch it.
Diving deep into shark-filled waters.
CASAGRANDE: Great white sharks, murky water.
-What could go wrong, right? -REX: Let's do it.
(splash)
(gurgling)
NARRATOR: With water visibility this bad,
the divers have no idea what's right behind them.
Andy joins the mission, camera in hand, ready to film
any unexpected visitors.
(gurgling)
Data collected and device reset.
It's a shark-free dive. Just another 26 receivers to go.
(rock music)
Below and above water,
it's a huge team effort.
And today's research is crucial to the long-term goal
of keeping people and sharks safe
in California and across the globe.
Because Santa Barbara isn't the only place
-to attract these predators. -(distant siren)
(beach chatter)
DR. CATHERINE MACDONALD: The list of coastal US cities
that has a shark population
is every US coastal city that I can think of.
It would be much easier to identify one city with no sharks.
NARRATOR: One of these urban shark spots
lies just 200 miles south of Santa Barbara.
La Jolla, California...
where the beaches are packed...
with sharks.
But unlike the more recent sightings at Santa Barbara,
sharks have been coming here for over 70 years.
And when this old school shark hot-spot...
(yelling)
...meets new school tech, the view...
(whirring)
from high above is unbelievable.
Over 400 leopard sharks
swimming amongst beach-goers, surfers, and boarders.
(dramatic music)
DR. ANDREW NOSAL: This site is unique because it's in an urban area.
I mean, here we are along one of the most popular beaches in the United States.
And so, we have these leopard sharks mixing it up with sunbathers
and people getting in the water, and so it kinda gives new meaning
to the hackneyed phrase "shark-infested waters."
(tense music)
NARRATOR: But a bird's-eye view of this hot-spot
is just the beginning of the story.
Drop back below the surface
and things get even more mysterious.
Leopard sharks are so called because of their striking markings.
Like their big cat namesake,
they are perfect predators.
Their spots act as camouflage,
as they stalk their prey, cruising the shallows,
before a final pounce.
(gurgling)
But swimmers here can bathe easy.
Leopard sharks only eat prey like crabs and octopus.
But here in La Jolla, California, even they are off the menu.
These sharks seem to have lost their appetite.
And that has Andy puzzled.
They're just swimming. You don't see them do really anything.
NARRATOR: If the sharks aren't here to hunt,
then why come to such a busy beach?
(tense music)
NOSAL: Oh, that's a shark.
-MAN: You got it? -NOSAL: Okay, I'm gonna...
NARRATOR: It was only by Andy studying individual sharks...
NOSAL: Yeah, we got it.
NARRATOR: ...that he made a breakthrough.
NOSAL: Nice big shark.
NARRATOR: Because these sharks are hiding a secret.
(dramatic music)
NARRATOR: Every summer...
La Jolla's beaches face a shark takeover.
NOSAL: Yeah, we got it.
NARRATOR: Shark scientist Andy Nosal is close to revealing why.
NOSAL: So, we definitely have a female here.
NARRATOR: There's something different about these sharks.
NOSAL: We're going to get ready to do an ultrasound on her now
because we want to see if she is pregnant.
NARRATOR: Leopard sharks can have anywhere between six to 36 babies.
NOSAL: Alright, so I see movement here. I see a moving embryo.
-So, this shark is definitely pregnant. -NARRATOR: In fact,
almost all of the leopard sharks here are pregnant.
So, for almost every shark, there's at least another six inside.
NOSAL: Now, that we know that these sharks
are all mature females, and not just that, they're all pregnant,
the way I look at them has changed, right?
I don't just see them as sharks now. I see them as moms...
(gurgling)
...swimming around, taking care of their babies.
Alright, I think she's ready. Off you go.
(gurgling)
NARRATOR: La Jolla, California, is a magnet for shark moms-to-be.
But why?
The answer could have something to do with another shark hot-spot.
One that's over 7,000 miles away,
on another continent.
(dramatic music)
Here in Israel,
sightings of dusky sharks are rare.
(gurgling)
Except for this beach, where every winter...
gangs of 10-foot predators
swim fin to limb with the local beach crowd.
(splashing)
And that's not even the craziest thing about this place.
This is.
(dramatic music)
An aerial view shows 40 to 50 sharks
making a site visit
to a power plant.
(water roaring)
So, what's the attraction?
A drone's-eye view shows they gather at the water outlets...
(water roaring)
...where water, used to cool the plant's turbines,
is pumped back out to sea.
Up to 18 degrees warmer than the surrounding water.
It creates a coastal hot spa that attracts sharks
and beach-goers.
And like the leopards in La Jolla,
scientists believe these dusky sharks in Israel
are all pregnant.
So could there be a connection between pregnant sharks
and warmer waters?
NOSAL: Most sharks are coldblooded.
So, if they're actively seeking out warm water patches,
they are regulating their body temperature. They're warming it up.
(gurgling)
Our hypothesis is that
they're incubating their developing embryos
in the warm, calm water,
like a mother bird sitting on her eggs to keep them warm
and maintaining that optimal temperature for development.
NARRATOR: If dusky and leopard sharks might be gathering in warm water
to help their babies grow strong...
could water temperature also explain the large gatherings
of great whites in Santa Barbara?
It's a theory the SharkLab team need to test.
Because while the sharks here aren't pregnant,
there is something unusual about them.
What's really interesting about all these sharks
that we're seeing along our beaches...
is that they're all babies. They're all young sharks.
Maybe this is the nursery.
(dramatic music)
NARRATOR: Santa Barbara...
is having a great white baby boom.
So, if you think these six-foot youngsters are big...
just imagine the size of the parents.
This baby shark revelation could help explain the surge in sightings.
We have some hypotheses. White sharks are incubated in a warm mom.
So, we think that female white sharks are probably giving birth
in deeper water somewhere offshore,
and those babies are suddenly exposed to cold water.
And their bodies are so small that they quickly lose the heat.
So, the young sharks actually are very temperature sensitive.
And we think that drives them towards beaches where the water's warmer.
SURFER: Right under the board. I am shaking like a leaf right now.
(waves crashing)
NARRATOR: To confirm their theory and find out if baby great whites
really are here to keep warm...
...SharkLab must launch the final stage of the stakeout.
-(beeping) -(whirring)
Time to bring in the big guns.
-What is this thing? -This is an autonomous underwater vehicle,
-or an AUV as we call it. -It looks like a shark missile.
Are you studying sharks on the moon now?
SPURGEON: Yeah, this thing is pretty crazy. We can tell it
how deep to dive, so this thing will dive
-about two meters from the bottom. -CASAGRANDE: No way!
NARRATOR: The robot will create a detailed temperature map
of California's new shark nursery.
SPURGEON: Once I get the data that the AUV collects,
I'm able to now match it up with the positions of the sharks
to determine if there's any pattern to where the sharks are moving.
Just like if I'm in a swimming pool, and I get to a cold patch,
I'm gonna keep swimming till I find a warm patch.
And so, I think sharks are making these similar decisions
in the habitat where they are regulating their temperature
and deciding where they wanna be.
Let's get this robot wet!
(rock music)
Okay. See you, buddy. Good luck.
(whirring)
NARRATOR: If there's a connection between great whites and temperature,
this robot will find it.
(whirring)
But over on the east coast, there's one town
that always brings the heat.
Miami, Florida.
Can this beach help explain
the link between sharks and water temperature?
Because it's not only the party-goers and beach-lovers
that cruise these beaches.
Just off shore, a hungry 20-foot shark
is looking for its next meal.
-(gurgling) -(dramatic music)
(tense music)
NARRATOR: Spring break in Miami.
The beaches are pulling in the people.
But less than 100 feet off the coast, another crowd is gathering.
WOMAN 1: Are you kidding me? Like, there's sharks out here right now?
MAN: Like, within swimming distance here? That's a little scary.
WOMAN 2: I'm not wild about that. I feel like there should be a sign.
NARRATOR: Every spring, Miami's beach crowd share the water
with thousands of sharks...
whether they realize it or not.
(splashing)
MACDONALD: The vast majority of human-shark encounters
are encounters that humans don't ever know about.
Sharks have incredible senses.
They know we're there when we don't know they're there.
(engine starting)
NARRATOR: One person that knows exactly what he's looking for...
(roaring)
is shark scientist and pilot Steve Kajiura.
DR. STEPHEN KAJIURA: If those swimmers down there could see all the sharks
that I'm seeing up here, they'd run for the beach.
(rumbling)
NARRATOR: Because an aerial view of the action reveals...
thousands and thousands
of blacktip sharks.
It's a spectacle
only visible from the air.
(rumbling)
Good numbers down there. Beautiful.
NARRATOR: The very best view down into the water
comes from high above it.
(dramatic music)
-(splashing) -(chatter, laughter)
(waves washing ashore)
But why are so many sharks coming to such a busy beach?
(gurgling)
Scientists think that just like their great white cousins in California,
they could be following the heat.
Every year, the blacktips make a 1,000-mile round-trip
up and down the east US coast,
a route that follows the warmest waters
and lands them in Florida every spring.
The exact same time...
...another group of heat-seekers rolls into town.
But today,
the shark beach party
is about to get crashed.
KAJIURA: Okay, there's a bunch of blacktips.
There's also something much bigger.
NARRATOR: A new visitor sends the blacktips running.
A bigger, hungrier shark.
A predatory hammerhead...
is cruising along the coast.
KAJIURA: Look at that! Cool.
These blacktips are patrolling back and forth along the beach,
and this hammerhead comes from deeper water,
up toward this school of blacktips.
(tense music)
NARRATOR: Hammerheads can reach up to 20 feet...
(gurgling)
...and weigh up to 1,000 pounds.
Apex predators.
They hunt everything, from octopus to fish,
and even...
...other sharks.
KAJIURA: We can see the big hammerheads coming in
and chasing these blacktips right up onto the beach.
Because these blacktips are half the size of the hammerhead,
the blacktips are able to get much shallower.
And the hammerhead can't do that. It has to, basically,
turn around and go back into deeper water.
NARRATOR: This time, the hammerhead's going hungry.
Scientists think the blacktip sharks
use these Florida beaches as a refuge from predators.
And back in Santa Barbara...
I got multiple sharks, multiple sharks on the drone here.
MAN: Copy that.
NARRATOR: ...with the survey in its final hour...
LOWE: Keep heading north, maybe try to cover another kilometer.
NARRATOR: ...Chris believes the young great whites
may also have a reason to hide.
While there aren't many predators crazy enough to chew a chunk out of
of an adult great white, it's a different story for youngsters.
LOWE: This is a safe place for them because we don't see
big predators like adult whites sharks or orcas along our beaches.
They're using this to ensure their survival for their first year.
If they can make it through that first year,
there's a really good likelihood they're gonna grow up to be an adult.
NARRATOR: Knowing these nursery waters are crucial to shark survival...
(drone whirring)
...puts more pressure than ever on today's survey.
CASAGRANDE: From the sky, the drones are picking up sharks
pretty much everywhere.
-How we looking on the AUV? -(radio beep)
SPURGEON: Yeah it's good. We've been seeing the robot
-and the sharks, so that's pretty cool. -(radio beep)
This is our last run in the area.
NARRATOR: The day is winding down.
-(whirring) -CASAGRANDE: Drone's coming in now.
NARRATOR: They've filmed, tagged, and counted.
And when the data is analyzed, even Chris is shocked by the findings.
LOWE: This is the first time we've ever seen anything like this.
(dramatic music)
NARRATOR: In Santa Barbara, the great white stakeout is complete.
CASAGRANDE: What's up, you little shark magnet?
Good job today.
Somebody's getting an extra charge tonight!
-Yes! -(whirring)
NARRATOR: Now, after months of data crunching,
the results for this beach can be revealed.
There are some big surprises.
LOWE: So, the stars really aligned for this day,
and it paid out because we got some truly amazing data.
(tense music)
So, what we can see here in magenta are all the people.
Swimmers, waders, stand-up paddle boarders,
and there's a big pocket of people
right here that are closest to these parking lots right here along the beach.
But then, when we look at the sharks in teal triangles,
we see that they're more spread out,
and there's a big cluster of sharks down here
where there are very few or no people sighted.
(waves washing ashore)
NARRATOR: So far, the sharks seem to be avoiding people.
(drone buzzing)
But, what about the sharks the drones can't see?
CREW MEMBER: Yes!
NARRATOR: Underwater tagging tech helps reveal the full picture.
-CREW MEMBER: Perfect! -NARRATOR: Throw in these tagged sharks,
the yellow triangles, and things suddenly look a lot sharkier.
(gurgling)
LOWE: Now, we see that there are sharks all along this area,
but also off the area where there's the highest concentration of people.
What our data show is that there are sharks,
like 20 or 30, at a beach with potentially
hundreds of thousands of people in the water, in and amongst them.
NARRATOR: An astonishing result.
That means footage like this is just the tip of the iceberg.
So just how many sharks are really out there?
The team's shark count focused on
one football field-sized section of California coast.
(beeping)
LOWE: So, Patrick counted
92 times where a shark had crossed that frame,
and you can see them because they're in different colors.
NARRATOR: In just one day, in one small section of coast,
a shark passed through here almost 100 times.
LOWE: The sharks are just kind of cruising back and forth,
just doing laps through that area.
NARRATOR: The team has revealed a secret shark nursery,
an important safe haven,
right off one of the world's busiest beaches.
But do more sharks up the risk factor?
LOWE: Sharks don't seem to change their path. They're not heading towards people.
(somber music)
Usually, the path seems to be like, "I'm going in this direction,
and there's a person here."
And as long as our thing isn't affecting their thing...
they don't care.
NARRATOR: But if the sharks are ignoring beach-goers...
...how do you explain footage like this?
SURFER: Oh my god. Right under the board. I'm shaking like a leaf.
LOWE: We do see, on occasion, sharks move towards people.
They may be curious. They could hear sounds and do a blow by.
They'll kinda swim kinda close, and then veer off.
Who knows? Maybe we entertain them while they're swimming around.
NARRATOR: Chris's theory is backed up by the stats.
Over the last decade,
Santa Barbara's beaches have been visited by growing numbers
of sharks and people.
Yet, there's not been a single shark bite.
Great news,
but it's not something to get complacent about.
Sharing the water with a wild animal always brings risks.
And this is where SharkLab
hopes to use the survey data to maximum impact.
By creating the world's first shark forecast.
(tense music)
NARRATOR: The results of a new and ambitious shark survey are in.
Santa Barbara's beaches are packed with sharks.
LOWE: If anybody were to tell me I would go out
right off my front yard in Long Beach and see a dozen white sharks
off the beach, I would have said you're crazy.
NARRATOR: Famous for its golden beaches, California is now a key destination
for a very different kind of beach crowd.
(gurgling)
LOWE: It is one of the most densely- populated beach communities in the world.
(seagull cawing)
We have 22 million people
that live within 60 miles of the coastline between Santa Barbara and San Diego.
And now, that habitat is also
the primary nursery habitat for white sharks.
(gurgling)
SURFER: Oh my god. Right under the board.
LOWE: Now, I, as a shark biologist, cheer, but not everybody cheers with me.
BOY: Oh my god! It's under you guys.
LOWE: There's concern about safety.
There's concern about the economic impacts if there are safety issues.
NARRATOR: What's most worrying
is that nobody knows where the sharks will show up next.
(tense music)
SPURGEON: These hot-spots can change from year to year.
They're not in the same beach every year, and we don't actually know why
the sharks choose which beach that they do.
NARRATOR: But if SharkLab can understand what the attraction is,
there's a chance to get smart about beach safety.
LOWE: I think we might be able to predict where sharks will show up in the future.
NARRATOR: The great white stakeout is part of a much bigger ambition.
(waves washing ashore)
A project that could be a game changer for public safety.
Because once SharkLab know which conditions attract sharks,
whether it's water temperature, or a maybe a threat from their predators,
they might one day be able to use that intel
to predict where and when the sharks will appear next.
REX: What we're trying to be able to do is create a shark forecast.
We can give that to the lifeguards.
We can give that to the public, so that they can make decisions
of where they want to go to the beach that day.
(dramatic music)
CASAGRANDE: Good morning, folks! It'll be about 85, cloudy,
with a chance of sharks. I like that.
Exactly! Some people will surf, and some won't.
SURFER: There you go, Rocco!
NARRATOR: It's an idea that's already being supported
by the Santa Barbara beach crowd.
(splashing)
LOWE: The locals have just come to accept the fact
that there are white sharks off their beach,
and they're adapting their behavior
because the sharks aren't going to change theirs.
(dramatic music)
This is their home. We're just visitors.
NARRATOR: Locals are learning to live in a shark hot-spot.
And while these events may seem new and shocking,
(gurgling)
they are, in fact, a great comeback story.
(waves washing ashore)
LOWE: In the last 100 years,
California's ocean has really seen dramatic changes.
(gurgling)
Commercial fishing,
development, loss of habitat for many marine species.
Chances are if you ate fish tacos in California
back in the early '90s, you ate white shark, and you didn't know it.
But, probably about 40 or 50 years ago,
we started to do things that fixed some of those problems.
In fact, 18% of the coastline is now marine protected areas.
NARRATOR: New environmental protection laws have helped shark numbers return.
(drone whirring)
And now, thanks to new technology,
we're finding ways to safely live alongside them.
(rock music)
LOWE: The fact that white sharks are coming back is a sign
that the whole ecosystem is getting healthier.
To have some success stories like this means
that we can fix things.
It gives you hope.
