Oceans in Peril

Oceans in Peril 

The oceans are the beating heart of our living planet. They regulate climate, absorb carbon, feed billions

By Geoffrey Holland

The oceans are the beating heart of our living planet. They regulate climate, absorb carbon, feed billions, and shape the rhythms of life itself. Now, after centuries of relentless human exploitation, this vast blue pelagic lifeforce is under extraordinary strain. The story of our seas is the story of human civilization — onward and upward in so many ways, but blind, until now, to the limits of its own massive, unsustainable appetites.

The Scale of Exploitation

Over the past seventy years, the exploitation of our oceans has grown to rival the land-based desecration of our Earth. Industrial fishing fleets now range across nearly every corner of our seas, extracting about 90 million metric tons of wild fish every year — roughly the same total we’ve maintained since the 1990s. In a few regions, like the North Atlantic and U.S. coastal waters, stricter management has stabilized declining stocks. But globally, the picture is troubling. The United Nations reports that more than one-third of all assessed fish populations are now overfished, compared to just 10 percent in the 1970s.

The Reasons are Familiar

It’s about relentless demand, subsidies that reward overexploitation, and weak enforcement in international waters. Massive trawler nets scour the seafloor, destroying coral and sponge habitats that took millennia to grow. Bycatch — the unwanted species that die in the nets — includes turtles, dolphins, sharks, and seabirds in the millions each year. 

Adding to this pressure is the shadow economy of illegal, unreported, and unregulated fishing. Estimates suggest it accounts for one in five wild fish caught worldwide. It’s a story of human inequity as much as ecological decline: fleets funded by wealthy nations often strip the waters of developing nations, leaving local communities impoverished and food insecure. 

In many ways, our ocean have become a microcosm of our planetary dilemma — a shared inheritance divided by greed, short-term gain, and the illusion that the natural world can withstand unchecked extraction.

Climate’s Rising Tide

As the climate crisis intensifies, our oceans bear the brunt. They have absorbed over 90 percent of the excess heat trapped by greenhouse gases. As a result, marine ecosystems are shifting and collapsing in real time. Fish populations migrate toward the poles in search of cooler waters, leaving tropical nations — often those least responsible for emissions — with empty nets. Ocean acidification, the result of dissolved carbon dioxide, weakens coral reefs and shellfish alike. Deoxygenation zones, starved of life-giving oxygen, now stretch for tens of thousands of square miles.

What we are now experiencing is a looming biological catastrophe, driven by what we humans must acknowledge as our own moral uncertainty. Our oceans are a mirror of our collective cultural choices — and they are sending an undeniable warning.

Flickers of Hope

Despite this sobering picture, there are encouraging signs. Human ingenuity, compassion, and the will to change are also forces of nature, and they are becoming ever more real in so many wonderfully reassuring ways.

More than 8 percent of our earth’s oceans are now designated as marine protected areas (MPAs) — places where fishing is restricted or banned entirely. While enforcement remains uneven, studies show that well-managed MPAs lead to dramatic rebounds in biomass, biodiversity, and resilience. When given space to recover, life returns with astonishing vigor.

Meanwhile, the rise of sustainable aquaculture — fish and seaweed farming done responsibly — offers promise. For the first time, farmed fish now account for over half of all seafood consumed. When managed with ecological awareness, aquaculture can relieve pressure on wild stocks, while also recycling waste, and even absorbing carbon.

And at the diplomatic level, the 2023 High Seas Treaty marked a historic milestone. For the first time, the nations of the world agreed to extend conservation and fair-benefit principles into the 60 percent of the ocean that lies beyond national borders. This initiative is imperfect, and fragile, and late — but it is a serious and worthy beginning.

The Nature of Interdependence

To redeem our relationship with our oceans, we must build around one profound truth: there is no separation between humanity and our Earth’s oceans. 

Every breath every human takes includes oxygen from plankton drifting in ocean currents. Every meal, every bit of rainfall; the stability of our world’s weather depends on our living oceans.

Earth’s natural worlds, including our oceans, are not owned by humans, we are linked to and dependent on them. We are inseparable from them. For humans, that recognition is the first step toward a global brand of informed gratitude. That kind of shared human expression, and the commitment that goes with it, inspires us to become the best kind of humanity we can be.

In the natural world, everything thrives on partnership — corals and algae, mangroves and fish nurseries, whales and the nutrient cycles they drive. The human species is the only kind of animal that has tried to stand apart and overreach. The result of our collective human overreach is ecological ruin on a global scale. 

Despite that undeniable reality, cooperation and planetary-scale partnership are our path to remaking oursleves. It can happen when fishermen, scientists, policymakers, and citizens choose to work together instead of being at odds; when nations work together and share data and enforcement rather than hiding behind sovereignty; when consumers choose seafood certified as sustainable; and when educators teach children that every drop of water connects them to our living seas.

A Path to Redemption

Redemption, in this context, does not mean atonement through guilt — it means reconnection through love and common interest. It means becoming open to the beauty of the ocean not as a resource to be owned, but as a living, biological partner in the great web of existence.

A partnership pathway for the seas could rest on five pillars:

1. Protection: Expand fully enforced marine protected areas to cover at least 30 percent of the ocean by 2030 — the “30x30” target that science says is essential for regeneration.

2. Regeneration: Support community-based fisheries and aquaculture that restore ecosystems instead of depleting them.

3. Transparency: Use satellite tracking, AI monitoring, and open data to end illegal fishing and hold industrial fleets accountable.

4. Education: Inspire a new generation to see the ocean as part of themselves — not a frontier to conquer, but a miracle to nurture.

5. Partnership: Foster collaboration among governments, industries, and civil society guided by the principle of common interest before private gain.

In truth, these same pillars define the broader transformation humanity must undertake if we are to find joy and harmony with our Earth. The oceans teach us that balance is not static — balance is dynamic, rhythmic, and responsive. Like the tides themselves, recovery is possible when the forces of destruction yield to those of renewal.

Toward a Living Covenant

A century from now, historians may look back on this moment as the time when humanity either turned the tide — or allowed our seas, all of our planet’s living systems, to slip beyond repair. Those of us here now must come together and choose our humanity over inhumanity.

If we can embrace a global commitment grounded in partnership — partnership between nations, partnership that includes all gender identities, partnership that binds all humans with the living systems that sustain us — if we do that, we will discover that redemption is not only possible, it is joyful and transformative. The health of our oceans can once again mirror the best reflections of the human spirit.

The same intelligence that built engines of mindless extraction can rethink and build a commitment to creative regeneration. The same human history that mindlessly plundered our seas can learn to revere and revitalize them. The same human species that brought the Earth to the brink of biological exhaustion can choose the better path. We can engage joyfully and choose to live in harmony with nature.

The path to global cultural redemption begins with common purpose inspired by cooperation and partnership. Where our oceans are concerned, that is the only tide worth following.
