In the course of making
Blue Planet 2, we've explored

every corner of the underwater
world. We've encountered

extraordinary animals.

And discovered new insights into
how life is lived beneath the waves.

For years, we thought that
the oceans were so vast and the

inhabitants so infinitely
numerous that nothing we could do

could have an effect upon
them. But now we know that was

wrong. The oceans are under
threat now, as never before in

human history. In this final
episode, we will meet the

pioneers who are striving to
turn things around. HE SQUAWKS

People who are helping to save the
oceans' most vulnerable inhabitants.

And dedicating their
lives to protecting the seas.

But is time running out? Many
people believe that our oceans

have reached a crisis point.
So, just how fragile is our

Blue Planet?

Winter in the Arctic Circle.

Every year, the waters of
Norway are the setting for one

of the greatest wildlife
spectacles in the ocean. Over a

billion herring pour into these fields.

The Blue Planet 2 team spent three
years documenting this astonishing event.

Such a wealth of prey attracts
predators in extraordinary numbers.

Orcas.

And humpback whales. HE SQUAWKS

But this migration hasn't
always been so bountiful. Leif

Nogestad is a Norwegian
fisheries scientist. It's been one

of the most important fisheries
that we had for centuries

along the whole coast of
Norway. But in the late 1960s, the

herring stock we see around us
here was on the brink of collapse.

50 years ago, fishing was so intensive
that the herring had all but disappeared.

Orcas were seen as rivals,
and hundreds of them were killed.

It was only after the Norwegian
government imposed severe

restrictions that the herring
began to recover. ORCAS

SQUAWKS

Today, this is once again
an immensely productive

fishery. Closely monitored
by teams of scientists.

Marine biologist Yves Jourdan
is one of the resident orca

experts. From 1982, orcas
got protected in Norway, and we

have clearly one of the largest
orca population in the world out here.

There are now over 1,000 orcas
here, but with so many mouths

to feed, including ours, can
the mistakes of the past be

avoided? To answer this vital
question, Yves and her team

are using multi-sensor camera
tags. With the tags, we try to

see how the orcas interact
with their prey, how they hunt,

and all about the underwater
behaviour that we are not able

to see from the boat.
The tag has to be attached

to the orca in exactly
the right position.

Here it comes, here it comes.

Ah, that's a good shot.

It is the least invasive
method, it is suction cups. So it

is not a scratch on the whale
afterwards, which is something

we really like.

While studying the orcas, Yves
noticed a worrying change in

their behaviour. They had
worked out the easiest way to get

a meal. We have seen that
the orcas are waiting for those

fishing boats to drop the
net. It acts like a dinner bell,

and then all the orcas of
the area gather. Quite a lot of

herring slip from the net,
and this is exactly what the

orcas are looking for.

But this new tactic is dangerous,
as Yves has witnessed. We

were there to monitor the
behaviour of the orcas, scavenging

around the net. And we
realised that one large adult male

was actually trapped inside
the net. When the fishermen

started to retrieve the net,
the orca was obviously starting

to panic and trying to pull as
much as he could. This orca

was really fighting for his life.

Stringent rules require
fishermen to get permission

before they open their
nets. But that took time.

It was such a long process. We thought that
the whale was going to die of exhaustion.

Thankfully, the fishermen
finally got the clearance

to release their net,
freeing the exhausted orca.

It was a huge relief to
see that this orca made it

until the end and finally
got back to his family.

With marine mammals and humans competing
so directly, accidents are inevitable.

Two days after attacking an orca,
it's released and Yves collects it.

This tag is full of secrets,
you know, because it has been

on the whale for several
days and we just reveal exactly

what the whales have
been doing. Pictures from

the tag reveal a hunting
technique in detail.

They dive below the ball of fish.

And then backflip.

The powerful tail slap stuns the herring.

Yves can even work out how
many fish the orcas are taking.

They can kill up to 30 herring
with just one tail slap. And

then what is pretty amazing
is all the individuals of the

group share the dead herring.
And it's not just the orcas

feeding here.

Humpback whales are
also drawn to the feast.

They too are being tagged
and monitored, giving fisheries

scientist Leif a complete
picture of how much herring is

being eaten. The whales,
they take probably less than 1%.

The fishermen take less than
10%. So the balance here is

that there is enough for
everybody, given that we manage

this stock in a sustainable and
a long-term sustainable way.

But it's estimated that almost a third of
ocean fisheries are being over-exploited.

The remarkable recovery of
the herring here demonstrates

what can happen if a
fishery is carefully managed.

Our maltreatment of the seas
has many effects. Some are

predictable. But there are
others that are rather more

surprising.

Southeast Asia. The coral
reefs are the most important

and the reefs here are
among the richest on the planet.

Marine biologist Steve Simpson
is discovering how important

sound is to the animals that
live in these bustling coral

cities. We're only now
just realising by listening

underwater that the fish are
making all these sounds. They

use sound to attract a
mate, to try and scare away a

predator. You hear pops and
grunts and gurgles and snaps.

There's a whole
language underwater that

we're only just starting
to get a handle on.

Using an advanced
multi-directional hydrophone, Steve is

trying to make sense of this
extraordinary chorus by working

out who is making which noise.

One fish is especially talkative.

It's perhaps the reef's most
famous resident, the clownfish.

While filming for the series,
we followed this particular

family of Saddleback
clownfish as they searched for a

suitable place to lay their eggs.

It's a noisy affair.

The clownfish sound, really,
is everything. They spend

all day talking to each other.
You've got dominance in the

submission, you've got all
the others calling to each other.

It seems that they also use
sound in protecting themselves

from the many predators
that hunt around the reef.

The clownfish are known to be the
most dangerous fish including coral trout.

Will this model trout fool the clownfish?

They react almost immediately.

By mimicking a predator, Steve
manages to record their alarm

calls without putting them at
risk. You can really hear the

deeper pulsing sound of the
female as she tries to scare the

coral trout away. And all the
little ones are just popping,

pop, pop, pop, as if to say,
oh, my God, I'm going to die.

I'm still OK, I'm still alive.
So they've got this real

language of sounds that
they're using just to try

and defend the colony
against this coral trout.

But that discovery has
led to a serious worry.

The fish were really popping
away at the predator. But

as soon as the boat came
over, they looked completely

distracted. With all that noise,
it completely changed how

the fish were behaving. Unable
to make themselves heard

above the noise of boats,
the family can't warn each other

of danger, and so they are
now vulnerable to attack. You

think about how many boats
are driving around, all the

ships, all of the offshore
drilling, and all the noise that

we're making in the ocean,
you realise just how much we're

drowning out this natural,
biological noise. Robbing animals

of their ability to be
able to talk to each other.

All this noise may have serious
consequences for many reef

fish because their babies, as
soon as they hatch, are swept

out to sea.

There, they feed and grow
until strong enough to swim back.

And to find the reef, they
use sound. They listen in, they

eavesdrop to the noises that
they can hear, and they use

that to choose which reef they
want to make their home. But

obviously, because we're
adding all this noise to the ocean,

it's a wonder whether they
can even hear the reef at all.

Man-made noise is now
everywhere in the ocean, and

it has an effect on marine
creatures of all kinds.

From tiny fish... ..to gigantic whales.

But Steve believes there are
solutions. Noise in the ocean

is a real problem, but it's
something that we can control.

We can choose where we make
the noise, we can choose when we

make the noise. We can directly
reduce the amount of noise

that we make, and we
could start doing that today.

HEAVY METAL RUMBLING
We're only now beginning to realise

what an impact our noise is
having on the inhabitants of the

ocean.

Other forms of pollution are only too
familiar. HEAVY METAL RUMBLING

Since its invention some 100
years ago, plastic has become

an integral part of our daily
lives. But every year, some

eight million tonnes of it ends up in
the ocean. And there, it can be lethal.

While filming Blue Planet
2, the crews found plastic

in every ocean. Even in
the most remote locations.

South Georgia.

900 miles north of Antarctica,
this isolated wilderness is

the breeding place for vast
numbers of penguins and elephant

seals. HEAVY METAL RUMBLING
HEAVY METAL RUMBLING

It's also a favoured
nesting site for the

largest bird in the sky.
The wandering albatross.

HEAVY METAL RUMBLING
Here we learned of the extraordinary

lengths aged parents go to
give their chicks the best chance

of survival. HEAVY METAL
RUMBLING Each devoted parent

travels thousands of miles
searching for fish and squid to

feed their hungry chick. HEAVY
METAL RUMBLING But despite

all their efforts, the albatross
colony here is in trouble.

Lucy Quinn is part of the
British Antarctic Survey Team

studying the birds here
for the last 40 years. It's only

through looking at long-term
studies that you get a sense

of these creatures and the
albatrosses here over the past 10

years have been in decline.
There are a number of possible

reasons. While foraging at
sea, albatross can get entangled

and drowned by fishing
gear. But Lucy is particularly

alarmed by what the parents
are bringing back for their

chick. Albatrosses have
the ability to cough up bits of

food that they can't digest,
and from that we can tell what

they've been eating. A
healthy albatross chick in its diet

should really have things
like squid, so we can find the

squid beaks that come out
of the pellet, and also things

like fish, so we can find
fish bones as well. But these

chicks are being fed something
very different. We have some

plastic that this poor chick
has had to bring up. Plastic

bag.

Here we have some food
packaging, looks like rice. Luckily

for this chick, he has
managed to get this out of his

stomach, so fingers
crossed he doesn't have any

more plastic left in
there before he fledges.

For other chicks, plastic can
be fatal. Unfortunately, there

was a plastic toothpick that
had actually gone through the

stomach. Something just
as small as that has actually

managed to kill the
bird. It's really sad to see.

Lucy collects and records what
plastic she finds around the nests.

These are all items that
were regurgitated just from last

season, and that's going to
be a vast underestimation,

because that's just the
ones that we happen to find.

There'll be many more that we
never see being brought back.

To find out where all this
rubbish is coming from, Lucy

and her team have attached
GPS trackers to adult birds.

It's showing where they're
going to find food for themselves

and to find food to bring
back for their chicks. It really

shows us that they could
be picking up plastic from

thousands of miles away.
Plastic's coming from either being

dumped at sea or also from
people's homes. Plastic gets into

the rivers, and then the
rivers flow into the sea. So this

isn't just a problem around
the nests, it's a problem around

these remote parts. This is
happening worldwide, and it's

our rubbish that's going into the oceans.
It's our problem that we need to solve.

In some parts of the ocean,
it's estimated that there are

now over one million pieces
of plastic for every square

mile. And we're only
beginning to discover

just how seriously
that affects marine life.

On the east coast of the
United States, researchers are

investigating the mysterious
deaths of young dolphins.

The team is led by Dr Leslie
Hart. It looks to be a young

animal, maybe a little bit
over a year. So we're going to

try to find out more information
on why this dolphin died.

Looking at young dolphins, the very
young dolphins, it's always heartbreaking.

Leslie takes tissue samples.
Their chemical analysis could

provide crucial evidence.
We have a very high probability

that it's a young dolphin. We
are often shocked by the high

levels of toxins that we
detect in these animals. These

young calves are dying
for a number of reasons, but

we suspect man-made
toxins are playing a large role.

And plastic could be part of the problem.

Once in the ocean, plastic breaks
down into tiny fragments. Microplastics.

Along with all the industrial
chemicals that have drained

into the ocean, these form
a potentially toxic soup.

The really small organisms
can mistake these tiny, tiny

plastics as food, and then
the larger organisms eat the

plankton, the larger fish eat
the smaller fish, and so on

and so forth. Dolphins are
at the top of this food chain,

and it's now thought that
pollutants may be building up in

their tissues to such a degree
that a mother's contaminated

milk could kill her calf.

INDUSTRIAL POLLUTION
Industrial pollution and the discarding

of plastic waste must be
tackled for the sake of all life in

the ocean.

INDUSTRIAL POLLUTION
Around the world, people are now

devoting their lives to saving
some of the most threatened

sea creatures. As here in the Caribbean.

Every year, on just a few islands,
a remarkable event takes place.

INDUSTRIAL POLLUTION As the
sun sets, giant reptiles begin to emerge.

This magnificent creature
preparing... Whoops! Preparing to

lay her eggs is the largest
of all turtles, a leatherback.

They can grow up to half a
tonne in weight, and they have an

ancestry that goes back 100
million years to the age of the

dinosaur. But in recent times,
their numbers have fallen

catastrophically. Here,
however, in the Caribbean, there is

hope.

Leatherback turtles leave the sea in
order to lay their eggs in the dry sand.

But out of water, these huge
creatures are easy targets for hunters.

In a small fishing village
in Trinidad, Len Peters has

experienced this first hand. I
grew up in a household where

the presence of turtle meat
was normal. The fridge was

always full of it. Everybody
harvests a turtle, including my

parents. It's only when I
became exposed to things that

were being published about
leatherback and the verge of

extinction, and nobody cares,
that piqued my interest. Len

took the leatherback's future
into his own hands. He began

patrolling the beach at night to
protect the turtles. A brave thing to do.

We were met with tremendous
resistance. People would pelt

us at night. I have had persons
insult me, I have had person

curse me, I have had person
physically try to harass me. I'm

a little machete. So it was
really a hostile time back then.

If Len was going to save these turtles, he
needed to win over the whole community.

We had to find a way
to get the villagers to

benefit from the
presence of these animals.

He began to encourage
tourists to visit the beach

and train some villagers
to be their guides.

To help secure the turtle's
future, he took the message

to the next generation.
Now, what's the largest size a

leatherback can grow to?
Er... Shani. 2,000 pounds. That's

correct. Leatherbacks can
grow to 2,000 pounds. That's a big

turtle. Len's hard work paid
off, and now attitudes have

changed. I just want to touch
base on some of the things we

wanted to accomplish tonight.
It took us a while to reach

out to the villagers, but
gradually we got them involved as

well. We got some of the
poachers who would be hunting the

animals to be part of the
conservation programme. As well as

protecting the adult turtles,
the team also collect any eggs

that might be flooded at high
tide. If the eggs are laid too

close to the sea, we relocate
the eggs and rebury them.

Thanks to the efforts of this
community, these turtles have

had an extraordinary change
in fortune. This is now thought

to be one of the densest
leatherback nesting beaches in the

world.

When we started, at the
height of the sea, the nesting

season, the numbers would
be 30, 40 turtles a night. Now

it's over 500. So we have
seen an increase from 40

turtles to 500 turtles a
night in just around 20 years.

Precious new hatchlings
are also given a helping hand.

Any that emerge during
the day are collected to be

released safely back to the
sea, away from hungry birds.

This little leatherback will
have to face 1,000 hazards

before it returns as an
adult to this beach where it

hatched. And those dangers
will be greatly increased because

of damage that we have done
to the oceans. Good luck, little

leatherback.

Protecting breeding sites on
beaches may improve the fortune

of some marine animals. But
safeguarding them while they

roam the high seas is much more difficult.

Out here, there is little protection.

Every night, thousands of
miles of fishing lines laden with

hooks are set. There's
enough, it's said, to wrap twice

around the world.

Nets large enough to engulf
cathedrals trap hundreds of tons

of fish at a time. Long-distance
travellers, such as sharks,

are particularly at risk.

It's estimated that tens of
millions are killed every year,

including the biggest fish
in the sea, the whale shark.

Shark biologist Jonathan
Greene is concerned that time is

running out for these extraordinary
creatures. We know that

they're being fished, possibly
at a massive rate. They may

be taken by the thousands,
possibly tens of thousands a

year. If that is indeed true,
we don't know how long they

can withstand that kind of
fishing pressure. To save them,

Jonathan is trying to solve the problem. To
solve the mystery of where they give birth.

And for the first time, he has a
clue as to where this might be.

Pregnant whale sharks are
thought to be travelling from

across the Pacific Ocean to
Darwin Island in the Galapagos.

Jonathan is going to try
and attach a multi-sensor

camera tag to a pregnant
female. OK, we're good to go?

These sharks only stay in the
area for a few days. This may

be his only chance. He's going
to try and find out where the

sharks are.

Jonathan has to attach the tag before
the shark dives to dangerous depths.

He's going to try and find
out where the sharks are.

The tag will remain
on the giant's fin for

two days before it's
automatically released.

Once retrieved, it reveals
some unusual behaviour.

What beautiful, beautiful...

There's a silky rubbing up
against the front. Next to a

rock. The silky is trying to
find out where the sharks are.

The sharks are brushing up
against her rough skin, perhaps

to scrape off parasites. These
predatory sharks make the

surface waters very unsafe
places for young fish of any kind.

There is a surprise in store.
The tag's depth centre reveals

that she dived to a depth of
600 metres. But down there,

it's too dark for the camera.

The only way Jonathan can prove if they're
giving birth is to go down and look.

Deep rover, deep rover,
control. You are cleared

to vent. Cleared to
vent. Have a good dive.

Out of the gloom, a shape materialises.

Another massive whale
shark. Look at her. She's

having a look at us.
She's looking right at us.

She is huge. And look at
the belly. Absolutely massive.

That's a large pregnant
female. And she's staring around.

She's staring around.

It goes to show. We can follow them.
We can follow them in the submarine.

She leads them down into the darkness.

Deep rover, control. Passing
100 metres. Descending.

Heading down. I think
she accelerated slightly.

She's too fast. And
with a strong current

running against them,
the sub can't keep up.

But for the first time,
she can. Jonathan can

see for himself exactly
where she's headed.

What specifically Darwin
could provide is a safe refuge

for those newborn pups where
predators can't access them.

Perfect conditions for the formative
years of these ocean -travelling giants.

Dream of a lifetime.

His discovery that pregnant
whale sharks are visiting this

very deep patch of the sea
floor is strong evidence that

this is indeed where the
giants produce their young. If I

can actually prove that they
are giving birth in this area,

then we'll have the
information necessary to go to

governments to actually say
you must preserve those routes

that they're migrating through.
And then and only then can

we really truly afford
protection to this beautiful ocean

-traveller.

Today, less than 1% of our
international waters are protected.

And the creation of marine
reserves is vital if we're

to safeguard the future
of many ocean creatures.

It will require international
cooperation, but here, too,

there is hope. We can turn
things around. We've done so once

before. For centuries, the
sea-going nations of the world

hunted the great whales until
they were close to extinction.

And then in 1986, those
nations got together

and agreed to put a stop
to commercial whaling.

Today, although a few
nations continue to hunt whales,

some of the great whales
are making a recovery.

In the tropical seas
surrounding Sri Lanka,

there are stories of vast
gatherings of whales.

When the civil war
ended in 2009, locals here

were able once again
to fish these waters.

There were soon reports of
the great whales being caught

in the sea. There were also
reports of assemblies of sperm

whales, the likes of which
had not been seen for centuries.

Marine guide Dyer was
determined to get to the truth behind

these fishermen's tales. The
fishermen told me that there

are lots of whales a little bit
north from here. They didn't

actually tell me a number,
but in big numbers, not one or

two, many.

It took him three years, but eventually he
found evidence to support these rumors.

We saw about 15 sperm whales go past us.

Then another boat came past us.

After about 40 went past
me, I started counting.

Still, they kept coming, so I lost count. I
estimated we saw about 300 sperm whales.

Sperm whales were once
killed in vast numbers, and it's

thought that if the slaughter
had continued, the species

would be in danger of extermination.

But now, here at least, they
are being seen in huge numbers.

I believe they come here to
feed, mate, raise their young.

So this must be a holiday
spot for them, you know. At the

moment, I don't know of any
other place in the world that

sperm whales gather like this.

Although some whale populations
are still in decline, scenes

like this prove that when
seagoing nations come together,

they can achieve astonishing results.

But today, the oceans face
threats on a truly global scale.

The Great Barrier Reef.

The largest coral reef system in the world.

Here, we film stories which
reveal just how smart fish can be.

This ingenious tuskfish,
for example, used a

favourite coral anvil to
smash open shellfish.

This astonishing behaviour
has been closely studied by

local scientist Alex Phail.
We call him Percy, Percy the

Persistent, because he took
like an hour to open the first shell,

He must have hit it well
over 50 times, but he

just kept on going and
finally he got it open.

Alex grew up on the Great
Barrier Reef, on one of its

more remote islands, Lizard.
He knows the reef intimately.

But in 2016, while he was
filming for Blue Planet 2, Alex

witnessed a catastrophe. When
we started filming, everything

was pretty much fine, all
of the corals were basically

healthy. But in the last few
weeks, everything changed. I

have never seen anything like this before.

A combination of a warming
ocean and an unpredictable

weather event called El Niño
raised sea temperatures to

record levels.

And this had a disastrous
effect on the corals. The heat

causes reef-building corals
to lose their nourishing algae,

exposing their white skeletons.

When temperatures remain
high, bleached corals die off.

The bleaching this year has
been the worst in history for

the Great Barrier Reef. About
90% of the branching corals on

the reef out here at Lizard
Island are dead. It also has

disastrous consequences
for the other creatures that live

here.

Percy, swimming around out
there, the really sad thing is

that his castle is starting to
bleach. If we lose our coral,

there's a chance we're
going to lose our tuskfish. It's

incredibly sad to see areas
that you have dived on since you

were a little kid just turn to rubble.

I cried in my mask
when I saw, you know,

some of the devastation
from this bleaching.

In the last three years,
over two-thirds of the world's

coral reefs are thought to
have suffered from rises in ocean

temperatures.

This is not the only challenge they face.

Research is revealing how the fundamental
chemistry of the ocean is changing.

Professor Chris Langdon shows
me what this might mean for

the future of our seas by
pouring dilute acid over shells.

And how much more acidic
is this than the present ocean?

This is more concentrated
than the pH of the ocean, but it

accelerates the process so
we can see something visually.

So what's happening is these
shells, they're made out of

calcium carbonate, and the
acid is dissolving them. And

coral reefs are made out of
the same material as these

shells here. But surely this
is not happening. So what's

happening in the ocean now,
right now? What we're seeing

here is more dramatic than
what's happening in the ocean,

but the shells and the reefs
are really, truly dissolving.

Coral reefs could be gone
by the end of the century.

And the cause of this?
Carbon dioxide. Dissolved in the

seawater, it forms carbonic
acid. The more carbon dioxide in

the atmosphere, the more
acidic the ocean becomes.

Evidence points to the
burning of fossil fuels as the

primary cause for these
increasing levels of carbon dioxide.

And this is man-made beyond
question? Beyond question.

But Chris believes all is not
lost. All we have to do, I say

all, is reduce our CO2 emissions.
We can switch to renewable

fuels, wind and solar,
instead of natural or fossil fuels.

And so none of this has to
devolve to the worst case. And

not to fix it. Yeah,
absolutely. So this future

does not have to
play out, it's up to us.

As the climate changes and the seas warm,
our oceans are being seriously affected.

And this is nowhere more
apparent than at the poles.

Antarctica. Yeah.

For the Blue Planet 2 team,
this was their most ambitious

expedition. For the first
time in history, a manned

submersible will try to dive
to a depth of 1,000 meters and

reach the Antarctic seabed. A
true journey into the unknown.

SO rover, hatch secure,
life support running.

Control rover, passing 4, 0 meters, over.

Leading the team on this historic
dive is deep sea scientist John Copley.

We get our first glimpse
of this landscape. And the

carpet of life around us is
astounding. That's beautiful.

Diving in a submersible
gives John an entirely new

understanding of how this
rich ecosystem works. But it also

offers him a unique opportunity
to investigate how the ocean

here is changing. While we're
observing the marine life down

there, the subs are also
recording what the environment's

like. So we're getting
measurements of temperature, of

salinity that's hopefully going
to enable us to understand

the changes that are
happening in this vital part of our

planet.

To get a fuller picture, John also
lowers a deep sea temperature probe.

His data is contributing
to an international attempt

to chart the rise in both
sea and air temperatures.

What shocks me about what all the data
show is how fast things are changing here.

We're headed into uncharted territory.

To truly comprehend the effect
of the temperature increases

here, John takes to the skies.
From here, he can record the

number and size of the
icebergs being produced as the ice

shelves melt and break apart.
The bergs we're seeing all

around us give you some
idea of how huge this process

is that's taking place on
the Antarctic. As the floating

shelves break up, they allow
water which has been locked up

on land as ice for thousands
of years to empty into the sea.

And this is predicted
to push up sea levels.

If the ice shelves break up,
then that opens the floodgates.

Ice on land flows faster into
the sea and that's what pushes

up the sea levels. So what's
happening here right now affects all of us.

Already, cities like Miami
here are under threat. Scientists

predict that by the end of the
century, the sea levels could

have risen by a meter or
even two. Were that to happen,

parts of this city would
certainly be submerged.

Around the world, the world
is changing. Around the world,

hundreds of millions of people
live near the coast, and as

sea levels rise, their lives
will be seriously affected.

It's now clear that our actions are having
a significant impact on the world's oceans.

During the four years it
took to make this series,

we've witnessed many
of these changes firsthand.

But we've also worked alongside
men and women, dedicating

their lives to safeguarding
the ocean's future.

The oceans provide us
with oxygen, they regulate

temperature, they provide us
with food and energy supplies,

and it's unthinkable to have a
world without a healthy ocean.

I still think we have the
capability to change the manner in

which we're wasting the
resources in which we're poisoning

our oceans, and we can look
to a future with healthy oceans.

When I look forward, I believe
that if what we are doing can

be duplicated just a little
bit, these animals will have a

chance of surviving. It
comes down, I think, to us each

taking responsibility for
the personal choices in our

everyday lives. That's all
any of us can be expected

to do, and it is those
everyday choices that add up.

We are at a unique stage in
our history. Never before have

we had such an awareness of
what we are doing to the planet,

and never before have we had
the power to do something about

that. Surely we have a
responsibility to care for our blue

planet. The future of humanity, and indeed
all life on Earth, now depends on us.
