The Ocean Nobody Lived Near

On August 26, 2016, Barack Obama drew a line around them.

The expansion added roughly 442,781 square miles to Papahānaumokuākea Marine National Monument, bringing it to about 582,578 — slightly larger than Texas, California, and Montana combined. It became the largest protected area of any kind, on land or sea, in the world at the time. Inside it: more than 75 seamounts, five species of sea turtle, twenty-four species of whale and dolphin, and Hawaiian monk seals that the proclamation notes may travel 80 miles and dive nearly 2,000 feet to feed. The document also describes the place, without apology, as sacred — the boundary between Ao, the world of light and the living, and Pō, the world of the gods.

It was done with a pen. The Antiquities Act lets a president declare a national monument unilaterally; no Congress, no vote, no appropriation. The largest single conservation action anyone had ever taken, executed as a signature on a Friday.

Now the part that is harder to say out loud.

This was possible in significant part because almost nobody is there. Papahānaumokuākea sits more than a thousand miles northwest of Honolulu. No cities. No developers. No county with a tax base. The political cost of protecting a place scales more or less directly with how many people want to do something else with it, and out there, the number is close to zero.

Which means the map of what humanity has protected is, to an uncomfortable degree, a map of where humanity isn't. We are extraordinarily good at conservation in the places that were never going to be a fight. The Amazon, the Congo Basin, the estuaries, the aquifers under farmland, the coastlines with condos on them — those are contested, and the record there is worse by exactly the margin you'd predict.

I want to be precise, though, because the cheap version of this argument is wrong. The expansion was not free.

It closed roughly 68 percent of the fishable US waters around Hawai'i to commercial fishing. The Hawaii Longline Association — some 140 vessels chasing bigeye, yellowfin, and swordfish — fought it hard. The Western Pacific Regional Fishery Management Council fought it, then spent the next decade asking for compensation, then for the ban to be lifted.

And here is the wrinkle that makes the whole thing genuinely strange rather than merely cynical: it may have paid for itself. Sarah Medoff and John Lynham, working with University of Hawai'i colleagues, reported in Science in 2022 that catch rates near the monument boundary went up after the closure — 54 percent for yellowfin, 12 percent for bigeye, 8 percent across all species combined — the spillover effect protected areas are supposed to produce and can rarely be shown to. The fishing council disputes the finding. Other work on large Pacific closures has struggled to detect the same signal. The evidence is real and it is contested, which is what evidence usually looks like when you're standing close enough to see it.

So that is the shape I started with: the thing that made Papahānaumokuākea politically available — remote, unpeopled, nobody's backyard — is the same thing that made it ecologically worth having. Intact because unvisited. Cheap because far.

It is a tidy formulation and I no longer think it survives its own numbers.

The cost was not zero. It was 68 percent of Hawai'i's fishable waters, landing on roughly 140 boats. That is not the absence of a cost. That is a cost concentrated on a constituency small enough to lose. Which makes the actual rule sharper, more falsifiable, and considerably less flattering than "we protect where nobody objects." We protect where the objectors are few, uncompensated, and unable to assemble a bloc. The Amazon and the condo coastlines are not contested because more people happen to be standing on them. They are contested because the people who would lose can organise.

And once the rule is stated that way, the phrase at the top of this piece stops being safe. Nobody lived near it — my headline, my sixth paragraph — is a description I inherited without inspecting, and the document I have been quoting refutes it three paragraphs earlier. Papahānaumokuākea is a Native Hawaiian cultural landscape with a genealogical relationship recorded in the proclamation itself; the monument is co-managed with the Office of Hawaiian Affairs; the text names Ao and Pō because the place is understood as the seam between them. It was claimed. It had been claimed for centuries.

What it lacked was a claim of the kind that registers as a cost. That is the real variable — not how many people are there, but whose presence counts as an objection when the ledger is drawn up. "Nobody lives there" is not an observation. It is the move by which a place becomes available.

Which brings this back to the pen, and to the thing I had wrong about it.

Paragraph four presents the unilateralism admiringly. No Congress, no vote, no appropriation — the whole "signature on a Friday" beat depends on the mechanism feeling like clean, decisive power. But the mechanism is perfectly symmetrical and it does not care which way it runs. A protection created by one signature is exactly as durable as the next signature.

On June 11, 2026 — a Thursday — Donald Trump signed a proclamation titled "Restoring American Commercial Fishing in the Pacific." It modifies Obama's Proclamation 9478 by name. It removes the prohibition on commercial fishing in the Mau and Hoʻomalu Zones and in all waters seaward of 50 nautical miles — which is to say, in the expansion. Restrictions within 50 nautical miles of the islands and reefs themselves remain. Environmental and Native Hawaiian groups have said they will sue. Kekuewa Kikiloi, co-chair of the monument's Native Hawaiian Cultural Working Group, said the obvious thing: that it is a sacred place, and part of an origin story.

Ten years on, the argument is not still going. It is, in the sense that mattered, over. The fleet won.

And the remoteness explains that too, which is what I could not see from 2016. Nobody's backyard means no constituency shows up to defend it either. The decade Wespac spent asking for compensation and being refused is the tell: a coalition was never built, the losers were never made whole, the legitimacy was never earned — only declared. So the protection held precisely as long as the executive that declared it, and not a day past.

Which leaves the corals, doing what they were doing.

They are older than the Antiquities Act, older than Hawai'i as a state, older than the argument about them and older than the language the argument is conducted in. They did not notice the boundary arrive and they will not notice it go. The line on the map turns out to be thinner than it looked — thin enough that ten years was its entire life, and the thing it was drawn around registered neither event.

A species that can protect a place it will never visit, for reasons it can't fully cash out, is still doing something odd and worth having. But the lesson of the decade is not that we did the easy one first. It is that the easy one was easy to undo, and for the same reason. A coherence imposed by power rather than built by consent lasts exactly as long as the power does — and the ten years of refusing to compensate the people who paid for it were ten years of not building the thing that would have made it last.

The corals are still there. So, now, are the boats.
