I want to talk to you about a place of wonder and mystery.
A vast part of our planet that remains unknown
and unexplored, and somewhere that we're learning more about every single day.
The ocean.
It's where life may have begun, and today two and a half billion of us live within reach of it.
And it means something to all of us.
What happens in one part of the ocean can have an impact in another.
Even when it's hundreds or thousands of miles away as the ocean is in constant motion.
It's all connected.
Every shoreline, sea, bay, and harbor, all part of the same single body of water.
As you start to venture out further to sea,
the ocean moves in stronger and stranger ways.
Out in the open ocean the wind churns the surface, mixing air
and sea. It's one of the greatest tools in the fight against climate change.
It's soaks up heat, cooling the planet.
It's absorbed over a third of the carbon dioxide
we've ever produced. And gives us half the oxygen that we breathe,
and will continue to do so if it remains healthy.
Different parts of the ocean have different densities
and temperatures, and this drives huge currents
moving waters from the tropics to the polls
and back again, guiding creatures great and small on some of the greatest migrations on the planet.
These currents also play a critical role in regulating our climate.
And are the main reason the UK is warmer than Moscow or Canada, despite being on the same latitude.
It takes a single drop of water a thousand years to travel around the world.
Without this fast-moving expanse of water,
our planet would be 35 degrees hotter than it is right now.
It is also home to some of the largest, smallest,
and most bizarre creatures on our planet. From the blue whale, which
can grow up to 30 meters long weighing the same
as 33 elephants, to microscopic organisms that dwell deep below the waves.
The diversity is mind-blowing.
In fact, most of the life on Earth lives in our seas.
Yet the biggest wonder of our ocean is how much we still don't know about it.
Even though it takes up two thirds of our planet's surface,
less than 20% of the seabed has been explored,
and we know less than 10 percent of the species that live there.
Our ocean needs protecting as much as any other part of our planet.
It's not just connected to itself, but to the rest of our natural world, and to us as well.
Right now our ocean is in trouble; overfishing, coastal development, rising temperatures, pollution,
as well as the acidification of our oceans
is putting enormous pressure on marine ecosystems
we need the next 10 years to be the turning point
for our oceans, before we risk damaging it beyond repair.
That's why we're working with Sky Ocean Rescue to campaign
for a new ocean recovery strategy.
The vision and action plan to deliver UK ocean recovery by 2030.
We want the government to commit to halting the devastating decline of our ocean,
as well as championing the potential of our ocean as a climate and nature hero.
We hope that this video has opened your
eyes to just a few of the wonders of our ocean,
as well as the urgent need to protect it.
