Since the turn of the millennium, one Marxist line of inquiry into environmental problems has outshone all others in creativity and productivity: the theory of the metabolic rift. Developed by John Bellamy Foster and his colleagues Richard York and Brett Clark, with crucial contributions from Paul Burkett and Marina Fischer-Kowalski and many others, it can be summed up in the following, highly condensed sequence. Nature consists of biophysical processes and cycles. So does society: human bodies must engage in metabolic exchanges with nonhuman nature. That need not be particularly harmful to any of the parties. Over the course of history, however, the relations through which humans have organized their Stoffwechsel might be fractured and forcibly rearranged, so that they not only harm the people disadvantaged by this change, but also, at the very same time, disturb the processes and cycles of nature. A metabolic rift has opened up.

Distilled through Foster’s pioneering exegesis, the theory makes inventive use of Marx’s comments in the third volume of Capital on how capitalist property relations "provoke an irreparable rift in the interdependent process of social metabolism, a metabolism prescribed by the natural laws of life itself"; operationalised in a variety of ways, it has elucidated everything from the imbalances in the global nitrogen cycle to climate change. 1 It is a method for tracking disruptive combinations of the natural and the social. In a recent tour de force of metabolic rift analysis, The Tragedy of the Commodity: Oceans, Fisheries, and Aquaculture, Stefano B. Longo, Rebecca Clausen, and Brett Clark start from the self-evident yet so often lost premise that "ecological concerns are not problems derived internally, originating from ecosystems themselves, but are produced externally, by social drivers. For example, the oceans are not polluting themselves; humans are doing it." That tragedy is possible, however, only because "human society exists within the earthly metabolism." 2 In the case of fishing — a primordial form of Stoffwechsel — a dramatic shift occurred in the middle of the nineteenth century, when companies armed with steamboats could catch hauls at new orders of magnitude; since then, but particularly since the post-war period, global fish stocks have come under lethal pressure. Rifts in the reproductive cycles of fish have opened up everywhere, from the bluefin tuna of the Mediterranean to the salmon of the Pacific Northwest — a result of how the elements of company and commodity mix with water. If this sounds like a theory and a method that abide by all the precepts suggested above, it is because any twenty-first-century ecological Marxism necessarily stands on their shoulders.

Of late, however, the metabolic rift school has come under sustained fire from Jason W. Moore. In a series of essays culminating in Capitalism and the Web of Life, he seeks to demonstrate that Foster and colleagues repeat the original sin of Cartesian dualism. The proof of their guilt lies, first of all, in their choice of conjunctions: they speak of nature and society, of interaction between the spheres, of capital as having an ecological regime. Moore wants the "and" replaced with an "in." It should be labour-in-nature, capital-in-nature, and so on — never and, the false bridge that betrays a worldview of nature/society as two hemispheres divided by a chasm. Likewise, one must not talk of metabolism between any two things, but always have to say through — and most essential of all: capitalism does not have an ecological regime, it is an ecological regime. By developing these series of conjunction swaps, in effusions of supposedly non-Cartesian language games of hyphenation and formulae, Moore proposes his "world-ecology" as a superior dialectical framework, to great acclaim from parts of the academic radical ecology community. 3

What the analytical advantages consist of, beyond a new terminology, is initially unclear. So, for instance, Moore faults Foster and colleagues for using the word "interaction" to describe the relation between nature and society, since this wrongly presupposes that the two can be separated to begin with — for two things to interact, they must first be apart — and proposes that we should instead ask how the two "fit together." 4 But exactly the same critique can of course be levelled against that choice of words. For two pieces to fit together, they must first be two different pieces. Moore himself seems forced to employ the foul conjunction in phrases such as "human and extra-human nature," "the soil and the worker," perhaps because a language of permanent in-hyphenation would be unreadable. 5 It certainly would not solve any real conceptual problems.

Why all this phraseology? It seems, at a closer look, that Moore has fundamentally misunderstood the requirements for transcending the Cartesian legacy. In a sentence of the kind repeated ad nauseam in Capitalism, he declares: "In place of a Cartesian optic — the 'exploitation of labor and nature' [words from Foster et al.] — I would begin with two forms of labor-in-nature." 6 But there is nothing Cartesian about saying "labour and nature." Foster et al. would be Cartesian if they thought that labour and nature consisted of different substances or inhabited separate spheres, so that the one could be analysed without reference to the other — a very common perception in the history of capitalist modernity but precisely the opposite of what the metabolic rift school teaches. As Foster himself retorts, "there is no contradiction in seeing society as both separate from and irreducible to the Earth system as a whole, and simultaneously as a fundamental part of it. To call that approach 'dualist'" — in the Cartesian sense — "is comparable to denying that your heart is both an integral part of your body and a distinct organ with unique features and functions." 7 What Moore does here is simply to succumb to the temptation of substance and property monism.

Beneath the arid semantic quibble, then, there is substantial disagreement on whether nature and society should at all be distinguished from one another. It is here that one finds the core of Moore’s theoretical project: an unbridled hybridism in Marxist garb. He has taken on the task of importing "the philosophical victory" of such thinkers as Neil Smith and Bruno Latour into the theory of capitalist development, setting out from a postulate that should by now be familiar: "The old language — Nature/Society — has become obsolete. Reality has overwhelmed the binary’s capacity to help us track the real changes unfolding, accelerating, amplifying before our eyes." 8 The aim of "world-ecology" is to act as a solvent on all related distinctions. "Put in these terms, the apparent solidity of town and country, bourgeois and proletarian, and above all Society and Nature, begins to melt." 9 Moore has found a way to abolish even the opposition between the classes — in language.

Several versions of hybridism are here banded together: much influenced by the production of nature theory, Moore opposes references to "a nature that operates independently of humanity," and to external limits, and to biophysical flows as having "ontological priority" over social relations, leading him right back into the blind alley: "We can dispense with the notion that something like climate change can be analyzed in its quasi-independent social and natural dimensions." If so, we can dispense with the notion of analysing it at all. Skidding in the other direction, Moore adopts the terminology of the material turn, defines agency as a "relational property of specific bundles of human and extra-human nature," dresses up water and oil as "real historical actors," attributes agency to climate as such, says that capitalism is "'co-produced by manifold species" and, logically, contends that coal formations were "subjects of historical change" in England. They were not, of course, in any meaningful sense of the word, subjects in what happened in England or anywhere else, and the picture does not become a speck clearer by labelling coal an "actant" possessing "agency." The singular achievement of Moore turns out to be a double collapse, such as in the following précis of his view: "Capitalism makes nature. Nature makes capitalism." 10 Neither of those propositions is true. Capitalism emphatically does not make nature; nature most definitely does not make capitalism. It is the utter disharmony between the two that needs to be accounted for, and it is that which the theory of the metabolic rift has so consistently foregrounded.

The double collapse partly flows from a view of dialectics as a method not so much for articulating antagonism as for achieving holism. It would be edifying here to keep in mind the admonition of Levins and Lewontin: "There is a one-sidedness in the holism that stresses the connectedness of the world but ignores the relative autonomy of parts." 11 Among the effects of that one-sidedness is that the parts disappear from view. Moore casts doubt on the belief "that such a thing as 'society' exists" and suggests that "entropy is reversible and cyclical," when entropy is defined by the second law of thermodynamics precisely as never being that. 12 With no laws of society and no laws of nature — what is there left to study?

On the other hand, there are, symptomatically, passages where Moore seems to accept the need for a binary of the social and the natural. When it comes down to saying something concrete about what capitalism actually does to (or in) the web of life, the explanatory model of historical materialism slips through cracks in the jargon. Now Moore argues that certain societies in the long sixteenth century developed the law of value as a new set of relations between people, which induced a complete shift in how these people related to non-human nature: for the first time in human history, "the law gives priority to labor productivity, and mobilizes uncapitalized natures without regard for their reproduction." Further, "a civilization premised on money and labor-time called forth a very different kind of time," based on which capital sought to remake material reality "in its own image, and according to its own rhythms": again, an impulse at changing nature emanating from property relations. Moore is then able to identify a clash "between the finite character of the biosphere and the infinite character of capital’s demands." Or: "Nature is finite. Capital is premised on the infinite" — hence ecological crisis. 13 And there we have the whole package again: a duality, a separation and conjunction, an attribution of inherent and antithetical properties, an intelligible argument about why capital must go berserk in nature.

Hybridism resists any juxtaposition between relations and laws of motion internal to capitalist society, on the one hand, and relations and laws of motion internal to nature on the other. But when Marxists write about the environment, they are pulled to the magnetic opposition between those poles. Take for instance the greatest classic of Marxist ecological feminism, The Death of Nature: Women, Ecology and the Scientific Revolution (which, contrary to appearances, contains no end-of-nature thesis). In this groundbreaking study from 1980, Carolyn Merchant traces the historical shift from a conception of nature as a mother to be revered and respected, an organic living being, sometimes benevolent and sometimes wrathful, to one of nature as a dead, inert object to be manipulated and controlled with maximum efficiency. The shift pivoted on a transition in social property relations in Europe, England in particular: starting in the fourteenth century, the English ruling class moved towards capitalist arrangements in agriculture, drained the fens, enclosed the fields, cut down the forests, removed the taboos on mining and pitted the peasant as worker against the landlord as capitalist. 14 Some priceless things were broken in the process.

The Death of Nature departs from the postulate that "natural and cultural subsystems" develop "in dynamic interaction." Moore would presumably disapprove of this wording, but it allows Merchant to identify a contradiction appearing at a specific moment in time: "Particularly important is the question of how environmental quality was affected by the transition from peasant control of natural resources for the purpose of subsistence to capitalist control for the purpose of profit." The latter type of property relations fathered a force that conflicted with environmental quality. "Built into the emerging capitalist market economy was an inexorably accelerating force of expansion and accumulation, achieved, over the long term, at the expense of the environment" — in the fens, for instance, the hitherto abundant wildlife collapsed as the pumps and windmills took over. It was this epochal transition that called forth the abandonment of the old conception of nature, which suited the novel relations and their inbuilt expansionary force poorly; instead, more and more people came to regard nature as a depot of resources to be owned and mastered. Since nature remained widely associated with women, this — the most well-known aspect of Merchant’s argument — translated into more aggressive subordination of the female body under the brute mechanisms of male power. At the end of her book, she turns to the environmental woes of the present and offers a strategic suggestion that has since become the stock of the trade of ecological Marxism: we need "a revolution in economic priorities." 15

Or, to take but one other example: in an excellent, long overdue Marxist intervention into the debate over the biodiversity crisis, Extinction: A Radical History, Ashley Dawson observes that "capital must expand at an ever-increasing rate or go into crisis." As it does so, "it commodifies more and more of the planet, stripping the world of its diversity and fecundity," puncturing holes in the web of life with incalculable consequences: "biologists are only just beginning to understand the cascading, ecosystem-wide impact of the destruction of the megafauna." 16 One emergent property comes into conflict with a whole planet of other emergent properties. This is the necessary and fundamental form of a Marxist account of ecological crisis, which does not exclude other drivers but centres on a feature unique for capitalist relations: the compulsion for perpetually expanding absorption of biophysical resources. Such a property cannot be found in nature. Any creature that had it would be fantastically maladaptive and quickly go extinct; capital has been able to maintain it into the twenty-first century only by establishing complete dominion over tellurian nature. But it cannot go on forever.

The ongoing sixth mass extinction looks particularly amenable to the sort of analysis outlined here. Thus we have strong evidence that the long postponement of the crackdown on the bustling London ivory market promised by the Tories has provided continuous incentive to criminal syndicates to slaughter African elephants and smuggle their tusks into Britain, but we have no signs of the elephants jumping off cliffs or otherwise committing mass suicide. 17 The biodiversity being torn apart is neither a human creation nor a source of agency in this disaster. On that environmental issue as well as on any other, it is possible to say something of ecological Marxist import only by practising property dualism.
