Ocean – Nature is Speaking – Harrison Ford

The Ocean helps us breathe; it helps to regulate climate; the ocean is an important food source; it has incredible biodiversity and creates tens of millions of jobs.


“I am the Ocean
I am water
I am most of this planet
I shaped it
Every stream, every cloud, and every raindrop
It all comes back to me.
One way or another
Every living thing here needs me
I am the source
I am what they crawled out of
Humans are not different
I don’t owe them a thing
I give, they take
But I can always take it back
That’s just the way it’s always been
It’s not their planet anyway
Never was, never will be
But human, they take more than their share
They poison me, then they expect me to feed them
Well it doesn’t work that way
If human want to exist in nature with me, and off of me
I suggest they listen close
I’m going to say this once
If nature isn’t kept healthy, human’s won’t survive
Simple as that
Me – I could not give a damn, with or without humans
I am the Oceans
I covered this entire planet once, and I can always cover it again
And that’s all I have to say.”


Five reasons why we need to safeguard the Ocean’s future.

1. It helps us breathe

Phytoplankton – tiny plant-like organisms that live in the sea – are responsible for at least 50% of the oxygen on Earth. Just like land-based plants, they contain chlorophyll to capture sunlight and use photosynthesis to convert it into the energy they need, producing oxygen as a byproduct. They also consume carbon dioxide, transferring about 10 gigatonnes of carbon from the atmosphere deep into the oceans each year.

2. It helps regulate the climate

The ocean absorbs huge amounts of heat from the sun. “More than 90% of the warming that has happened on Earth over the past 50 years has occurred in the oceans,” according to the US National Oceanic and Atmospheric Administration.

That heat tends to be at its most intense nearer the equator, with the water nearest the surface warming the most. Sea currents then transport that heat around the world; north and south, towards the poles. As some of the sea water evaporates it becomes denser and heavier, due to its relatively higher salt content. That causes it to sink, taking some of the warm water deeper.

Some currents are directly responsible for specific climatic effects. One example is the Gulf Stream, which takes warmer water from the Gulf of Mexico across the Atlantic to Europe. If the Gulf Stream were disrupted, much of the western part of Europe – including the UK, Ireland and France – could become colder.

3. It’s an important source of food

Fish is on the menu for billions of people around the world every day. It accounts for almost 16% of all animal protein consumed globally. Of course, there’s more to seafood than fish, crustacea and other edible creatures. A range of algae and sea plants are also commonly used in cooking.

The UN Food and Agriculture Organization lists sodium, calcium, magnesium, and iodine among some of the important nutrients in seaweed. Iodine deficiency has been identified as the “most prevalent and easily preventable” cause of impaired cognitive development in children.

Pressure on resources and the environment have led to calls for food production and for people’s diets to change. A cow, for example, produces 2.8kg of greenhouse gas per kilo of live body weight and needs 10kg of feed for every kilo it weighs.

Plus, to get just one gram of protein from cattle, you need 112 litres of water. The oceans, if properly managed and maintained, could form an important part of a more sustainable approach to feeding the planet’s growing human population.

4. Its biodiversity is incredible

It’s not just a source of food. The ocean is also home to an abundance of life. While estimates on the number of species that live in the sea exist, no one knows with absolute certainty what that number is.

According to the US National Library of Medicine’s National Institutes of Health, “91% of species in the oceans still await description.” That’s due in no small part to the vastness of the oceans, which cover around 70% of the planet’s surface and are up to 11,000 metres deep. The number of yet-to-be-discovered creatures living in the sea could easily run into the millions.

One example of how mysterious the deep oceans can be is the coelacanth. Found in fossils and believed to be extinct, a living coelacanth was pulled out of the ocean in 1938 off the coast of South Africa.

This fascinating deep-water creature could yield invaluable insights into how marine animals were able to adapt to life on land, as the way they move their fins resembles the way many four-legged creatures walk.

5. It creates millions of jobs

By 2030, ocean-based industries will employ more than 40 million people worldwide, an OECD report estimates. The biggest share of those jobs is likely to be in the fisheries sector, followed by tourism.

The economic health of maritime industries is fundamentally linked to the overall health of the oceans, of course. The ocean economy is of particular importance in developing countries, which are home to most of the 3 billion people who rely on the sea for their livelihoods.

Challenges like climate change, pollution and a simple lack of awareness of sustainable ocean stewardship techniques continue to put maritime resources at risk. That will limit the potential socioeconomic benefits those resources represent for future generations, as well as stifling people’s earning abilities in the present.

It regulates rainfall and droughts, holds 97% of our planet’s water, and absorbs CO2, helping keep the carbon cycle in balance. From food to jobs, it’s a lifeline for billions of people, too.

But the ocean is also a beautiful natural environment with an invaluable recreational role to play. And with research showing a connection between spending time in the natural world and lowering your stress levels, that might be something else worth holding on to.
