Atacama lithium extraction exacts heavy social and environmental toll

The Brine and the Kingdom of Ends

The principle operating here, stated plainly, is: When an end is urgent enough for humanity as a whole, I may draw the means to it from the land and water of those few who live far from the people the end will serve. Let us ask whether this principle, universalised, produces coherence or contradiction.

First, what is actually done in the Atacama. Lithium there is not dug like coal. It is pumped up as brine from beneath the salt flats and left to evaporate in vast shallow ponds under the Chilean sun. In the driest non-polar desert on earth, the product is, in effect, water removed from a place that has almost none. The communities who have lived around these flats for generations, the Lickanantay among them, do not experience this as an abstraction about supply chains. They experience it as a question about which lagoons will hold water next season and whether the pastures will hold.

Now universalise. Let every agent adopt the maxim that urgent global ends license drawing means from the remote. The trouble begins with the word “remote,” which is not a property of a place but a relation between places. The Atacama is remote from Stuttgart and Shanghai. Stuttgart is remote from the Atacama. A law of nature under which every place may be spent for the benefit of whoever lies elsewhere is a law under which every place is spent. Each region becomes, at once, the sacrifice and the beneficiary, and the distinction the maxim depends on, between those who pay and those who are served, dissolves. The maxim cannot be thought as universal without destroying the very asymmetry that made it attractive. It survives only as an exception its holders grant themselves, and a principle that survives only as an exception is not a principle at all.

The defender of extraction will not be moved by this, and should not be, until I have met his strongest argument. He says: the climate crisis threatens hundreds of millions of persons, the poorest first; the transition to electric storage requires lithium; to halt the Atacama pumps on grounds of conscience is to choose clean hands over drowned deltas. This is not the argument of a cynic. It is the argument of a man who has counted the stakes honestly.

But observe what grounds his argument. Why does the climate crisis command us at all? Not because carbon is ugly, but because persons, present and future, have a dignity that a warming world would trample. The entire moral force of the transition comes from the principle that no human being may be treated as a mere instrument of others’ comfort. And here lies the contradiction the defender has not noticed: he proposes to honour that principle by suspending it for a particular group of human beings, chosen because they are few and far away. He would rescue the kingdom of ends by evicting some of its citizens. His will contradicts itself, not at the level of outcomes, but at the level of the reason he gives for wanting the outcome.

There is a distinction that resolves this, and it is not a technicality. The duty to mitigate climate harm is a wide duty: it obliges us to pursue an end, but leaves open how. The duty not to use persons merely as means is strict: it binds the how. A wide duty may never be discharged by violating a strict one, just as a debt to one creditor may not be paid with money stolen from another. Nothing in this forbids lithium. It forbids lithium obtained on terms the people of the salt flats could not rationally accept, terms that hide the water accounting from them, decide their aquifers in ministries they do not sit in, and offer royalties as though a lagoon were a commodity they had agreed to sell.

I confess some amusement at the moral bookkeeping of the age. A battery carries the label “clean” because its emissions occur nowhere in particular, and its costs occur somewhere very particular indeed. The label is not false. It is only written from the point of view of whoever is holding the car keys.

The duty, then, is this: extraction may continue only where those who bear its cost are treated as co-legislators of its terms, with the right to know, to refuse, and to be heard before the pumps are switched on, not after the lagoon is gone.

Somewhere in a showroom far from Chile, a buyer runs a hand along a silent car and feels he has done his part. The water that made it possible will not be coming back to the flat it left.
