3306. Misrepresenting Marx’s Ecology: A Response to Daniel Tanuro’s “Was Marx an Ecosocialist?

By John Bellamy Foster, Monthly Review, January 14, 2020

Daniel Tanuro is an agricultural engineer and leading socialist activist who has made numerous contributions to ecosocialist thought and practice, most notably, in his book Green Capitalism: Why It Can’t Work.(1) Yet, this has been coupled with persistent claims that there are “fundamental flaws” in Karl Marx’s ecological critique of capitalism.(2) Tanuro has previously charged that Marx failed to recognize the centrality of fossil fuels to capitalist industrialization, and that Marx discounted peasant/indigenous knowledge by rejecting French agronomist Léonce Lavergne’s notion that forage crops were capable of obtaining all the nutrients they needed directly or indirectly (through manure) from the atmosphere.(3) These and other criticisms of Marx by Tanuro were refuted by Paul Burkett and myself in our book Marx and the Earth (2016).(4)
Tanuro has now shifted his argument in a number of ways, requiring a further response. In his recent review “Was Marx an Ecosocialist: A Reply to Kohei Saito,” on Saito’s Karl Marx’s Ecosocialism, Tanuro has dropped his accusation that Marx and Engels ignored the role of fossil fuels—something that did not hold up in the face of the mass of evidence to the contrary. Instead, he now faults Marx for being unaware even in the context of his time of the global energy imbalance caused by the anthropogenic emissions of carbon dioxide into the atmosphere.(5) He follows this up with the charge that Marx incorrectly denied that some plants could obtain nitrogen from the atmosphere, while coupling this with the observation that Marx also neglected the role of earthworms and soil organic matter in soil fertility.(6) Tanuro asserts that both of these were parts of traditional peasant knowledge, which Marx “disdained.” Additionally, the role of earthworms, he notes, was emphasized in Charles Darwin’s The Formation of Vegetable Mould through the Action of Worms (1881).(7) Finally, Tanuro claims that Marx and Engels’s well-known failure to develop a full critical analysis of the expropriation of women’s unpaid domestic labor is related to these general ecological failures.
Marx’s ecological conceptions were naturally limited by the nineteenth-century material conditions and knowledge. Marxian ecology does not rest simply on what Marx and Engels knew or didn’t know about concrete ecological problems, relative to our own time, but rather on their overall critical method. Nevertheless, it is important to scrutinize the “orrery of errors” that Tanuro himself manufactures in his misrepresentation of Marx’s ecological views.(8)

Marx and Nineteenth-Century Ecological Knowledge

In “Was Marx an Ecosocialist?” Tanuro deftly underscores the importance of Marx’s theory of metabolic rift as explored most recently in Saito’s Karl Marx’s Ecosocialism. Yet, he criticizes Saito for “exaggerating” the importance of Marx’s ecological critique. This is followed by an attempt to single out certain ecological shortcomings in Marx’s argument. Tanuro’s initial criticism of Marx is to say, “As far as I know, the possibility of a global energy imbalance in the Earth due to the burning of fossil fuels did not catch his [Marx’s] attention. It could have been otherwise—John Tyndall discovered the radiative power of CO and other atmospheric gases in 1859. But Marx’s interest in science was mostly focused on other areas of research. (Let’s add that [Carl] Fraas [whom Marx studied] was talking about local climate change caused by deforestation, not global warming.)”(9)
In saying that “it could have been otherwise,” and that Marx could have recognized both the earth’s energy imbalance and global warming if his interests in science had not been “mostly focused on other areas of research,” Tanuro is in effect suggesting that Marx is to be judged not by his understanding of the science of his day, but rather by his failure to supersede it. Here a few facts are in order. Although Tyndall had empirically demonstrated that carbon dioxide played a role in producing a greenhouse effect, neither he nor anyone else in Marx’s lifetime put forward the hypothesis of anthropogenic global warming. This had to await the Swedish scientists Svante Arrhenius in 1896.(10) Marx, it is worth noting, attended some of Tyndall’s lectures at the time that the latter was presenting his experiments in relation to solar energy and carbon dioxide. Marx was also aware of general speculations with respect to the role of human production in earth warming—though lacking any clear scientific basis—from his studies of the work of the early Marxist ecological economist Sergei Podolinsky.(11)
There was in fact no such thing in Marx’s day as a developed theory of the energy balance of the Earth System. The concept of energy itself (as distinct from force, motion) was still fairly new in the mid-nineteenth century—having been introduced in the context of the scientific revolution associated with the development of thermodynamics, to which Marx and Engels paid close attention.(12) It was not until the 1958, that Mikhail I. Budyko in the Soviet Union published the first estimates of global energy balance in his Heat Balance of the Earth System.(13) The concept of the Earth System itself was thus a late twentieth-century creation.(14)
As Tanuro partly acknowledges, Marx was influenced by the work of the German scientists Carl Fraas and Matthias Schleiden, who documented climate changes in ancient societies. Marx and Engels were also aware of the environmental effects of colonialism on islands like St. Helena (and even in parts of India). Thus, they referred a number of times to local climate change associated with deforestation. Marx carefully took notes from the work of geologist Joseph Beete Jukes on the movement of isotherms due to paleoclimatic change and their effects on species extinctions in geological time over tens of millions of years.(15)
In addition to questioning Marx’s understanding of Earth System changes, Tanuro goes on to challenge Marx for his criticisms of Lavergne’s Rural Economy of England, Scotland and Ireland (1853). Marx derided what he called Lavergne’s “fairy story” with respect to forage plants and soil fertility. Tanuro contends that this amounted to a denial of nitrogen fixation in the soil on Marx’s part. Thus, Tanuro points to what he takes to be: the fact that Marx considered the notion that certain plants could fix nitrogen from the air in soils as a fable…. I think there is little doubt that Marx…expresses a disdain [for this reason] for what he sees as the superstitions of peasants (and those of indigenous peoples). We find a trace of this scientism in Marx’s admiration for Liebig’s theory that chemical nutrients are the main explanation for soil fertility: it is certain that peasants knew the role of earthworms and other organisms of soil fauna—a role confirmed by Darwin in 1881—but peasant knowledge did not hold the attention of Marx.(16)
Tanuro is alluding here to Marx’s objection to Lavergne’s extraordinary claim that “Forage plants derive from the atmosphere the principal elements of their growth, while they give to the soil more than they take from it.”(17) In fact, Marx was entirely correct in treating this as a bourgeois nursery tale, indicating that both parts of Lavergne’s statement were fallacious. It is not true that forage plants, even in the case of legumes, derive from the atmosphere all the principal elements of their growth. Like all other plants they depend largely on nutrients from the soil. For most plants only carbon dioxide plus atmospheric oxygen (which plays a secondary role in removing the waste electrons in the respiratory process and does not enter directly into plant growth) are obtained from the atmosphere. The remainder of the sixteen essential chemical elements have to be obtained by most plants from the soil, including nitrogen. However, legumes (such as clover, peas, and beans) can utilize atmospheric nitrogen and fix it in the soil (with the help of bacteria at their roots). But even legumes are dependent on the soil in order to obtain all the other essential chemical elements in plant growth (aside from carbon dioxide, oxygen, and nitrogen). And all plants exhaust the soil, requiring soil chemicals to be recycled. Lavergne’s contention that legumes give to the soil more than they take from it is therefore wrong—as Marx contended.(18)
Nowhere in all of this does Marx go so far as to deny that some plants (legumes) are capable of drawing nitrogen from the atmosphere and fixing it in the soil (a fact that had been demonstrated by Jean-Baptiste Boussingault in 1836, though the exact mechanism by which it occurred was not known until 1880). Moreover, Marx makes no reference at all to nitrogen in this context, so there is no basis for Tanuro’s charge that he denied the existence of nitrogen fixation. Logically, to challenge, as Marx did, the “fairy story” that forage plants get from the atmosphere all of the “principal elements of their growth” is not the same as to adopt the fallacious notion that they get none of these chemicals from the atmosphere. Nor does this say anything about nitrogen specifically. Liebig, who was Marx’s principal source on soil chemistry, had concluded by the third edition of his Agricultural Chemistry in 1843 that the nitrogen that plants obtained from the atmosphere was “quite sufficient” (a position, however, that did not distinguish legumes from plants in general) so that additional nitrogenous fertilizer was unnecessary. Although this conclusion was rightly questioned at the time by farmers and scientists, Marx, would have had little reason on this score to doubt the reality of nitrogen fixation.(19)
Marx’s wider opposition to Lavergne was based on the latter’s advocacy of English high farming with its emphasis on meat-based agricultural system geared to the consumption of the rich, as opposed to a cereal- or grain-based agricultural system geared to the consumption of workers. Far from denying peasant knowledge in this sphere, Marx, as one would expect, was questioning the new, meat-based system of English industrialized agriculture and generally siding with the common people (the people of the commons) and their traditional agricultural practices.(20)
But what of Marx’s neglect of earthworms and other soil fauna in his treatment of the soil? Here Tanuro is undoubtedly correct that this received no attention from Marx,  mainly because major advances in science in this area required the study of soil microorganisms, which had not yet occurred in Marx’s day. It is true, as Tanuro points out, that Darwin published his book on earthworms in 1881, but this was a mere two years before Marx died (one year before Darwin’s own death). Still, it is hardly possible to argue on this meager basis, as Tanuro does, that Marx had “a disdain for what he sees as the superstitions of peasants (and those of indigenous peoples),” or that he was guilty of “scientism.”(21) One has only to look at Marx’s very detailed treatment of the forms of spade cultivation practiced by the Irish peasantry, including their management of the subsoil, to disprove the allegation of his disdain for peasant cultivation.(22) Moreover, Marx’s Ethnological Notebooks and writings on the indigenous more generally contain numerous detailed investigations into indigenous agricultural methods.(23)
With respect to gender, Tanuro throws out logic altogether, contending that Marx’s famous statements in Capital and in the Critique of the Gotha Program that nature and labor are the two sources of wealth constitutes a direct indication that Marx took “into account neither the reproductive work mainly performed by women, nor the specific exploitation of female employees.”(24) This seems to be based on two presumptions strangely attributed to Marx: (1) women’s reproduction in the household does not belong to the categories of either corporeal nature or social labor, and cannot be seen as producing real wealth in the form of use values; (2) labor in industry is mainly to be identified with men and excludes women. In contrast, Marx recognized the importance of the reproduction of labor power within the family (while failing to investigate this sufficiently) and could not even have conceived of the idea of reducing all of social labor to capitalist commodity production, which would have undermined the entire basis of historical materialism. Moreover, he indicated in Capital that women were the bulk of the laborers in the main value-generating sector, particularly textiles, in the Industrial Revolution. He carefully examined the specific conditions of women’s labor, as in the chapter on “Modern Domestic Industry” in volume 1 of Capital.(25)
There is no question that Marx and Engels only tangentially dealt with the problem of domestic labor and the fact that women’s contributions to social reproduction in the household were not compensated within the capitalist system. This then is a clear shortcoming in their political-economic analysis. True, there were historical reasons for this in their time, since proletarian women were not stay-at-home housewives in this period—even if they still carried on their backs the main household tasks—but spent the majority of their hours slaving in factories (together with men and older children). The result was that the working-class family was in a state of dissolution, giving rise to the protectionist movement that subsequently relegated women increasingly to the home. Nevertheless the theoretical gap in the analysis of the social reproduction of labor power constituted a crucial weakness in Marx’s critique of capitalism.(26) Marx’s fundamental methodology, together with the recognition of the shortcomings of his analysis in this area, however, has opened the way to the revolutionary development of social reproduction theory over the last half-century, and particularly in the last decade or so.(27) One of the results of this analysis is the growing recognition that capitalism has to be understood in terms of a dialectic of exploitation and expropriation, with the latter including the robbery of both domestic/subsistence labor and nature.(28)

The Centrality of Marx’s Ecological Critique

Tanuro concludes that Saito’s Karl Marx’s Ecosocialism though important is “exaggerated and counterproductive” in its contention that the thrust of Marx’s critique was to put ecological contradictions increasingly at the center of the analysis. Yet, in understandably asserting that the exploitation of labor power was more important to Marx than the expropriation of nature, Tanuro artificially divides what Marx thought was a dialectical unity, the robbing of both “the soil and the worker,” failing to understand that, as a materialist, Marx invariably went to the root of the problem: the metabolic rift generated by capitalist production, which was at the same time the ultimate manifestation of the alienation of human species-being.(29) “The irreparable rift in the interdependent process of social metabolism, a metabolism prescribed by the natural laws of life itself” was not to be viewed as a separate reality, but rather as the deepest material consequence of the alienation of human labor.(30) It is this unified critical outlook that makes Marx’s work an indispensable starting point for understanding capitalism’s creative destruction of the earth as a place of human habitation.

3305. Was Marx an Ecosocialist? A Reply to Kohei Saito

By Daniel Tanuro, International Viewpoint, January 12, 2020

Kohei Saito’s book Marx’s Ecosocialism is an essential contribution to the current debates on Marxism and the environmental question. [1] What makes Saito’s work particularly interesting is that it traces the evolution of Marx’s thought from a “productivist” to an “anti-productivist” vision of human development, in particular by incorporating natural limits into perspectives for agriculture. This historical approach allows the author to transcend the quarrels between Marxists who see Marx’s ecology as a glass which is empty, half empty, half full or full.
Thanks to careful reading of Marx’s Notebooks, Saito brilliantly shows how Marx abandoned the idea that agricultural productivity could increase indefinitely under socialism until, in 1865-1868, he came to the opposite conclusion that only socialism could stop the absurd and destructive capitalist tendency to unlimited growth.

John Bellamy Foster, in his book Marx’s Ecology [2], highlighted the impact of Liebig’s work on Marx’s understanding of the problem of soil depletion. Like Foster, Kohei Saito considers that the disruption of the exchange of matter between humanity and nature (metabolic rift) - caused by the combined processes of enclosures, capitalist industrialization, urbanization and the breaking of the cycle of nutrients that resulted - is a fundamental concept of “Marx’s ecology”.

But Saito goes further: he shows that Marx, because he still believed in the unlimited potential of agricultural production, was initially interested in Liebig because the German chemist provided arguments against Ricardo’s “law of diminishing agricultural returns” and Malthus’s “theory of absolute overpopulation”. However, in the seventh edition of his “Agricultural Chemistry”, Liebig distanced himself from his own overly optimistic positions, “recognizing that there are natural limits to agricultural improvements” and concluding that fertilizers could not compensate for “robbery agriculture”.

“Liebig did not highlight his change of position,” says Saito. But Marx was so focused on the debate over the (non) proportionality between agricultural productivity and capital investment “that this hidden modification did not escape him.” On the contrary, he remarked that “the new formulation [of Liebig] implied a critical point of view on agriculture subjected to profit by capitalist relations, incapable of improving the soil sustainably and in the long term”.

For Saito, the German chemist’s turn was “decisive” for Marx’s break with productivism. Hence the fact that this rupture occurred “relatively late”, from 1865. Saito writes: “In the London Notebooks, the Prometheanism of Marx is always discernible, but, having integrated Liebig’s reversal, he corrected, during 1860s, his own optimistic view of the possibilities of agriculture.”

Of course, Marx did much more than correct his vision based on the work of Liebig. The chemist was a great scientist but also an industrialist producing fertilizers for profit. He had no social or historical understanding of soil depletion. Marx, on the contrary, immediately perceived the parallel between the exploitation of labour and the destruction of nature by capital. From this moment, he saw the two phenomena as a common result of mediatization by the abstract value of the relationships between humans as well as between humans and their environment.

Kohei Saito rightly insists on the general importance in Capital of the concept of a humanity-nature “metabolic rupture”. Even if Marx concentrated on agriculture and other sectors directly exploiting natural resources (forestry for example), it is obvious that the concept, for him, transcends the problem of soil exhaustion to include all trade of material (Stoffwechsel) between humanity and its environment. Agriculture is a starting point, because Marx had a major theoretical interest in the question of rent, and he saw the enclosures as “the great tearing apart” of the relationships between humans and nature.
We can only agree with Saito when he emphasizes that Marx saw the “breaking of the metabolism” as a global phenomenon, aggravated in particular by the imperialist plunder of colonised countries, such as India and Ireland for example. Thus, Marx was aware that the nutrients included in Indian cotton manufactured in British factories would never return to the soils where the cotton had grown. This is another example showing that “Marx did not integrate Liebig’s theory passively but quite actively, applying it to his own political analysis.”

The historical approach by Saito to the evolution of Marx’s thought on the issue of natural limits is similar to that used Kevin Anderson in his book Marx At The Margins, devoted to non-Western societies - another area where the views of the author of Capital changed remarkably. For Saito, there is a link between these two research fields since Marx, in his Promethean period, “attributed soil depletion to the technological and moral backwardness of so-called primitive farming techniques.” In this regard, it is undoubtedly likely that “Marx’s critique of modernity deepened during his investigation of natural sciences in 1865” as Saito says.

On the basis of his careful study of Marx’s Notebooks Saito argues that Marx nuanced his enthusiasm for Liebig after 1868. The reasons could be twofold: first, Marx could only oppose the development of Malthusian tendencies in Liebig’s thinking; secondly, he discovered the work of other scientists, especially Fraas who defended the idea that nature, under certain climatic and alluvial conditions, could compensate for the loss in the soil of nutrients absorbed by plants.

For Fraas, Liebig “magnified the risk of soil depletion, in order to popularize his theory of fertilizer.” Moreover, Fraas also supported the idea that agriculture, because it involves deforestation, brings local climate change which in the long term results in the decline of civilization. It is clear that such a theory would stimulate Marx’s thinking on the conditions for a “rational management” of human-nature metabolism.

The concept advanced by Saito of an “unfinished critique of political economy”, particularly in the field of ecology, creates an adequate framework for debates between Marxists, not only on the assessment of the work of Marx but also on research fields open to continuing the development of an eco-socialist alternative.

I leave aside Saito’s criticisms of my own work on the theme of “Marx and ecology”. According to Saito, “Daniel Tanuro maintains that the Marx era is now so distant in terms of technology and natural sciences that his theory is not appropriate for a systematic analysis of current environmental issues, in particular because Marx did not pay enough attention to the specifics of fossil energy compared to other forms of renewable energy.” This criticism is so contrary to my writings for over 20 years that an answer is superfluous.

In my opinion, there is indeed something like an “ecology of Marx”, but it is incomplete and sometimes contradictory. If I really appreciate “Marx’s Ecosocialism”, it is precisely because Saito gives a dynamic, historical and consequently non-apologetic explanation of this incomplete and contradictory character. What is more, he gives this explanation without falling into the Althusserian theory (false, in my opinion) of the so-called “epistemological break” in the development of Marx’s thought.

It is certain that ecosocialists have different opinions on the degree of incompleteness and contradictions in Marx’s ecology. At the end of his chapter “Capital as a theory of metabolism”, Saito devotes a few pages to the “contradiction of capital in nature”. I am in general agreement with the content of this text, but it essentially consists of a (re) construction of Marx’s ecology by Saito himself. I admit that Marx could possibly have written something like this at the end of his life. But he did not, probably because he was not confronted with the global ecological crisis.

Saito says that Marx “did not elaborate on the waste of natural resources in as much detail as on the cruel exploitation of labour power”. It is indeed the least we could say. Therefore, it is, in my opinion, exaggerated and counterproductive to claim that Marx would have analysed “the problem of the ecological crisis as the central contradiction of the capitalist mode of production.”

It seems to me preferable to consider “Marx’s ecology” as an unfinished project. The practical question, therefore, is: “what should we, as ecosocialists, do to continue the work?” Obviously, the priority is to apply the brilliant concept of capitalist rupture of metabolism to ecological imbalances other than the depletion of soils, on which Marx focused. As far as I know, the possibility of a global energy imbalance in the Earth system due to the burning of fossil fuels did not catch his attention. It could have been otherwise - John Tyndall discovered the radiative power of CO² and other atmospheric gases in 1859. But Marx’s interest in science was mostly focused on other areas of research. (Let’s add that Fraas was talking about local climate change caused by deforestation, not global warming.)
But the most important ecosocialist task is clearly to identify new areas of research, fuelling new programmatic developments. In my view, three areas are particularly fertile from an ecosocialist point of view.

The first is the deep connection between the exploitation of nature, exploitation of labour and oppression of women by the patriarchy. Marx’s formula (in Capital) on “the only two sources of all wealth, nature and the worker”, takes into account neither the reproductive work mainly performed by women, nor the specific exploitation of female employees. This specific exploitation and oppression constitutes a pillar of capitalism, as important as the exploitation of nature and that of labour in general.

The second area is the necessary break with scientism. This is an important question because scientism had an influence on Marx (and even more on Marxists of the 20th century). As an example of this influence, I mentioned the fact that Marx considered the notion that certain plants could fix nitrogen from the air in soils as a fable. Saito replies that “it is expeditious to criticize Marx on this one point”: what Marx rejected as fable, according to him, was not the possibility of this mechanism but Lavergne’s idea that it could favour short term crop growth. However, I maintain my interpretation. I think there is little doubt that Marx in this quote expresses a disdain for what he sees as the superstitions of peasants (and those of indigenous peoples). We find a trace of this scientism in Marx’s admiration for Liebig’s theory that chemical nutrients are the main explanation for soil fertility: it is certain that peasants knew the role key of earthworms and other organisms of soil fauna – a role confirmed by Darwin in 1881- but peasant knowledge did not hold the attention of Marx (who was on the other hand quite aware of the knowledge of artisans).

The third area is the place and the role of peasants in contemporary capitalism. Marx believed that peasants were doomed to disappear by the evolution of capital, but the reality was different. Because of the gap (identified by Marx) between production time and labour time in agriculture, capital chose not to invest directly in agriculture in the strict sense but to indirectly control upstream (machinery, seeds and so on) and downstream (processing, distribution and so on). The result of this process is that a large fraction of the peasantry (and even more of the landless peasantry) does not act as an intermediate class oscillating between bourgeoisie and proletariat but rather as a layer opposed to the multinationals and financial capital. This is why peasants often play a vanguard role in ecosocialist struggles, as seen in the action of Via Campesina. The strategic implications of this should be discussed carefully by ecosocialists.

In The German Ideology, Marx and Engels defined communism as “the real movement which abolishes the present state of things”. They added that “the conditions of this movement result from the premises now in existence”. Because it defines “Marx’s ecosocialism” as an “unfinished criticism of political economy” and underlines the general direction of its development, the works of Kahei Saito constitute a powerful invitation to ecosocialists to unite in order to debate and collaborate in the elaboration of a new eco-communist program.
