If there were a place that embodied what British environmentalists claim to cherish, it would be the Chagos Archipelago.
Sixty low lying islands scattered across the Indian Ocean, ringed by vast coral reef systems, with waters thick with tuna, sharks, turtles, rays and reef fish, and skies crowded with seabirds. For decades, this has been one of the least disturbed island chains on Earth.
Britain has spent half a century keeping it that way.
The UK has resisted tourism, commercial development and speculative exploitation. Only one island, Diego Garcia, is inhabited. The other fifty nine remain given over entirely to wildlife. The surrounding seas have been treated as a sanctuary, patrolled at UK public expense, with vessels intercepted, trawlers driven away and illegal fishing deterred. Britain did not do this for profit. It did it for conservation, and for the global commons.
This was not cheap. It required ships, surveillance, administration and political will. It required saying no, again and again, to commercial interests that would have liked to turn paradise into revenue.
Now all of that is being placed at risk by a Labour Government determined to transfer sovereignty to Mauritius, a country more than a thousand miles away, which has already spoken openly about issuing fishing licences and seeking to monetise the territory.
Mauritius does not have the same record in Chagos because it has never had responsibility for Chagos. It is a poor country that does not have permanent patrol assets in the region. It recently required assistance from another country simply to reach the islands in order to conduct a symbolic visit. Distance matters in conservation. Capability matters even more.
And yet MPs and peers who habitually proclaim their devotion to environmental causes have fallen conspicuously silent.
Where are the urgent questions in the Commons about enforcement, resourcing and future protection. Where are the speeches in the Lords from Labour demanding binding conservation guarantees before sovereignty is surrendered. Where are the Green MPs, who campaign tirelessly on marine protection at home, but appear curiously absent when confronted with one of the most extraordinary marine ecosystems for which Britain is currently responsible.
The risk is not abstract.
These waters contain commercially valuable species. Once licensing regimes change, once budgets tighten, once political pressure grows to generate revenue, the temptation to allow industrial fleets closer access becomes relentless. It is how overfishing happens everywhere, not through sudden catastrophe, but through gradual erosion of restraint.
Open the door a crack, and it rarely closes again.
That is why sovereignty matters environmentally, not as a flag waving exercise, but because it determines who makes the rules, who pays to enforce them, who says no to short term profit, and who has the ships and power to back that up.
Instead of grappling with these realities, Parliament has pressed on. Conservative, DUP and non-affiliated peers have tabled amendments seeking greater scrutiny, environmental protections and transparency over the deal. Again and again, Labour Peers and MPs have voted them down. The Green voices, so audible on other ecological battles, have not registered.
This is not principled environmentalism. It looks far more like political convenience.
Because the uncomfortable truth is that Chagos does not fit neatly into fashionable categories. It is a British administered territory with a superb conservation record, and that makes it awkward for those whose instincts are always to assume the worst of British stewardship, even when the evidence points the other way.
Britain has not exploited Chagos. It has preserved it, at considerable cost, for decades, for scientists, for biodiversity, and for future generations who may never visit, but who benefit from its existence all the same. The Chagossians themselves overwhelmingly want to remain British too.
To hand that record over without ironclad guarantees, without demonstrated capacity, without long term funded enforcement mechanisms, and without proper parliamentary scrutiny is not progressive. It is reckless.
If Green politicians genuinely believe what they say about protecting fragile ecosystems, this is the moment to prove it.
Because environmentalism is not supposed to be selective. You do not defend coral reefs only when it is comfortable. You do not champion biodiversity only when it aligns neatly with party loyalties.
You defend it precisely when the politics are difficult.
The Chagos Islands are not an abstraction. They are a living system, a rare refuge in an ocean under mounting pressure.
If Parliament allows that to be gambled away, history will not be kind, and neither will voters who were told that environmental protection was non negotiable.
Silence, in this case, is not neutrality.
It is complicity.
