(Continuing our series on metabolic rifts.)
As we’ve seen, metabolism, a defining feature of all life, always involves exchanges with the world outside the organism. Life cannot exist without ingesting matter and excreting waste. The fact that the Earth is a sphere surrounded by a vacuum, and that we have access only to its outer few kilometers, means that the amount of matter available for life to use is finite, and that life’s wastes have nowhere else to go.
If metabolisms were linear, if inputs were simply consumed, the nutrients needed by living organisms would soon be depleted. Plants could consume all the carbon dioxide in the atmosphere in about 8,000 years, and all the nitrogen in a million years. Life has lasted far longer than that because its support systems are circular. Vast recycling operations endlessly reprocess and reuse essential elements and compounds. Radical biologist Barry Commoner described the Biosphere as “a closed, circular system, [in which] there is no such thing as ‘waste’; everything that is produced in one part of the cycle ‘goes somewhere’ and is used in a later step.”(1)
This permanent recycling regime would be impossible if Earth were a totally closed system — because, as the second law of thermodynamics says, totally closed systems eventually run down. Entropy (disorder) increases until everything comes to a stop. Fortunately for us, while the Earth System is closed to external matter apart from occasional meteorites, it is open to external energy.(2) The constant inflow of light and other radiation from the Sun, combined with the existence of organisms that can convert solar energy into chemical energy, makes endless recycling — and thus all life — possible. All biogeochemical cycles are ultimately powered by photosynthesis.
The nineteenth century scientists who discovered the circular metabolic processes that make life possible tended to view them as local or regional. The idea of global metabolism wasn’t even considered until the twentieth century — and even then it was a minority view until almost the twenty-first.
The first scientist to undertake a serious study of the dynamic relationship between life and the Earth as a whole was the Russian geochemist Vladimir Ivanovich Vernadsky. Born in 1863 and educated in St. Petersburg, Munich and Paris, by 1900 he was well-known both as a geologist and as a liberal opponent of Tsarist autocracy. A founder of the Constitutional Democratic (Kadet) Party and member of its central committee for many years, he represented the universities’ constituency in the Duma (Parliament) from 1906 to 1911, when he resigned to protest government attacks on academic freedom. In 1915, he founded the Commission for the Study of the Natural Productive Forces of Russia (KEPS), to identify sources of strategic raw materials: its work continued under the Soviet government until 1930. Although he opposed the Bolshevik revolution, he resigned from the Kadets when the party supported military action against the new government. After the Civil War, he returned to Petrograd and resumed his position as head of the Academy of Sciences.
In the early 1930s, Vernadsky criticized the government’s takeover of scientific institutions, and objected to attempts to impose dialectical materialism as an official and mandatory philosophy. He frequently intervened privately to aid scholars who faced official censorship or persecution. But for the most part he refrained from publicly opposing Stalin’s policies, to avoid endangering his scientific work. He wasn’t a Marxist, but he was a Russian patriot, eager to contribute to the country’s development, and that probably saved him from the fate of many other scientists in the purges. As his biographer notes, “it was not uncommon for Stalinists to worry more about Marxists with whom they disagreed and whom they distrusted, than they did about non-Marxists who worked loyally for the regime, did not intrigue, and were no real threat to Stalin’s position.”(3)
In 1922, while studying and teaching in Paris, Vernadsky wrote “A plea for the establishment of a biogeochemical laboratory,” and sent it to scientific bodies in Europe and the United States, hoping to get international funding, but only the Soviet government responded positively.(4) He established his laboratory — really a small research institute — in Leningrad in 1926.
Vernadsky’s focus on biogeochemistry — he created both the word and the science —reflected his conviction that the composition and principal characteristics of our planet could not be explained by geology and chemistry alone. “I realized,” he later wrote, “that the basis of geology lies in the chemical element — in the atom — and that living organisms play a prominent role, perhaps the leading one, in our natural environment — the biosphere.”(5)
He summarized his views in 1926 in the pathbreaking book Biosfera (The Biosphere). Geologists had long recognized the existence of three “envelopes” surrounding the Earth’s crust — atmosphere (air), hydrosphere (water), and lithosphere (soil and rock). The biosphere was a fourth, “a specific, life-saturated envelope of the Earth’s crust,” comprising all living matter on Earth, and all parts of Earth where life exists, from the crust to the upper atmosphere.(6) His argument was revolutionary in two major respects: it treated the entire planet as an object of study, and it identified life itself as a major factor in creating shaping the planet.
No chemical force on Earth is more constant than living organisms taken in aggregate, none is more powerful in the long run. The more we learn, the more convinced we become that biospheric chemical phenomena never occur independent of life…
Life is, thus, potently and continuously disturbing the chemical inertia on the surface of our planet. It creates the colors and forms of nature, the associations of animals and plants, and the creative labor of civilized humanity. And also becomes a part of the diverse chemical processes of the Earth’s crust. There is no substantial chemical equilibrium on the crust in which the influence of life is not evident, and in which chemistry does not display life’s work.(7)
He described organisms as “transformers” that use solar energy to power their metabolic relationships with the rest of the planet. “This transformation of energy can be considered as a property of living matter, its function in the biosphere.”
The radiations that pour upon the Earth cause the biosphere to take on properties unknown to lifeless planetary surfaces, and thus transform the face of the Earth. Activated by radiation, the matter of the biosphere collects and redistributes solar energy, and converts it ultimately into free energy capable of doing work on Earth.
The outer layer of the Earth must, therefore, not be considered as a region of matter alone but also as a region of energy and a source of transformation of the planet. To a great extent, exogenous cosmic forces shape the face of the Earth, and as a result, the biosphere differs historically from other parts of the planet. This biosphere plays an extraordinary planetary role.
The biosphere is at least as much a creation of the sun as a result of terrestrial processes.(8)
He identified recycling as a central feature of global metabolism.
The biosphere’s 1020 to 1021 grams of living matter is incessantly moving, decomposing, and reforming. The chief factor in this process is not growth, but multiplication. New generations, born at intervals ranging from tens of minutes to hundreds of years, renew the substances that have been incorporated into life.
Because enormous amounts of living matter are created and decomposed every 24 hours, the quantity which exists at any moment is but an insignificant fraction of the total in a year.
It is hard for the mind to grasp the colossal amounts of living matter that are created, and that decompose, each day, in a vast dynamic equilibrium of death, birth, metabolism, and growth.(9)
In a 1938 article, he described the intimate connection of living organisms with their environments through metabolic processes.
Living organisms are connected with the biosphere through their nutrition, breathing, reproduction, metabolism. This connection may be precisely and fully expressed quantitatively by the migration of atoms from the biosphere to the living organism and back again — the biogenic migration of atoms. … There is no natural phenomenon in the biosphere more geologically powerful than life….
Between the living and inert matter of the biosphere, there is a single, continuous material and energetic connection, which is continuously maintained during the processes of respiration, feeding, and reproduction of living matter, and is necessary for its survival: the biogenic migration of atoms of the chemical elements, from the inert bodies of the biosphere into the living natural bodies and back again.(10)
Until his death in 1945, Vernadsky and his co-workers conducted cutting-edge research on the composition and dynamics of the biosphere. A recently-translated selection of papers he wrote in that period includes articles on the oxygen and carbon cycles, the organic origins of coal and petroleum, the sources of atmospheric carbon dioxide, and more. I was particularly struck by one that showed that “the Earth’s atmosphere itself, consisting primarily of oxygen, nitrogen, and carbon, is the creation of life.”(11) In these areas and others, Vernadsky’s work was well ahead of science in other countries.
Humans and the Biosphere
Vernadsky insisted that biogeochemistry was not concerned with life as such. Science could not explain life, so discussions of it tended to be “permeated with philosophical and religious concepts alien to science.”(12) Nor did biogeochemistry study individual organisms: that was the domain of biology. Biogeochemistry addressed planetary questions, so its concern was with the planetary impact of “living matter as a whole — the totality of living organisms.”(13)
He did not, however, adopt the artificial holism that is sometimes invoked as an alternative to dualism. As the research topics listed above show, Vernadsky was fully aware of the need to investigate parts of the biosphere in order to build a picture of the whole. He was certainly aware that many planetary cycles can’t be understood without knowledge of the differing metabolisms of the species involved — for example, his work in the 1930s included consideration of the different planetary impacts of autotrophs (organisms that live by photosynthesis) and heterotrophs (organisms that live by directly or indirectly consuming autotrophs).
Above all, he was very aware of the unique biospheric impact of one particular species: homo sapiens.
Long before he developed his views on the biosphere, Vernadsky’s practical work as a geologist made him aware of the destructive effects of extractive industries on the environment. In 1913, for example, after visiting the nickel and cobalt mines in Sudbury, Ontario, he wrote home to his wife:
This new technology—American technology—which has given so much to mankind, has its dark side. Here we see it in everything: a beautiful land has been made ugly, the forest burned out; for tens of miles the land turned into a wasteland, all plant life poisoned and burned out, and all of this in order to achieve a single goal: the quick mining of nickel.(14)
After the revolution, he and two of his former students convinced the Bolshevik government to ban mining and other commercial activity in a geologically significant region of the southern Urals. On May 4, 1920, Lenin signed a decree establishing that area as the first territory anywhere in the world to be protected for scientific study.(15)
In the 1920s, Vernadsky began to consider whether intelligent matter (humans) might be overwhelming the impact of the rest of living matter. In his 1926 book The Biosphere, he noted that human intelligence had enabled the species to “reach places that are inaccessible to any other living organisms,” which made it difficult to determine what the limits of the biosphere might be.(16) What’s more, humanity was making unprecedented changes in the “film of life” that covers the land.
Civilized humanity has introduced changes into the structure of the film on land which have no parallel in the hydrosphere. These changes are a new phenomenon in geological history, and have chemical effects yet to be determined. One of the principal changes is the systematic destruction during human history of forests, the most powerful parts of the film.(17)
More research into biogeochemical cycles made it evident that economic activity was changing the global metabolism in measurable ways. This passage, from an essay Vernadsky wrote in the 1930s on the carbon cycle, has a very modern feel.
The release of carbonic acid [carbon dioxide] by Man in the process of his technical work is considered biogenic, such as the release occurring in factory furnaces, calcinating lime, fermentation, and in many other processes. Is a very interesting and characteristic fact in the history of carbon that the quantity of carbonic acid released by mankind in this way increases with the progress of civilization. It has already reached such an order that it must be taken into account in the geochemical history of the biosphere.
Thus, according to A. Krogh’s calculations, the quantity of carbonic acid released by the consumption of coal reached 7×108 tons in 1904, and rose to 1×109 tons in 1919 (F. Clarke). This amounts to as much as 0.05% of the entire mass of carbonic acid existing in the atmosphere. Such an increase acquires the status of an important geochemical phenomenon. In this way, civilized Man breaks the established terrestrial balance. With the civilization of Homo sapiens, a new geological power has appeared…(18)
Entering the Noösphere
In the 1930s, Vernadsky concluded human activity was creating a new planetary envelope that he dubbed the Noösphere (pronounced no-osphere), from nous, the ancient Greek word for mind or intelligence. He borrowed the word from Pierre Teilhard de Chardin, a Jesuit priest and geologist he met in the 1920s in Paris.
That borrowing has been a source of confusion, since the two men defined the word in radically differently ways. Teilhard, a Catholic mystic, defined the Noösphere as the spiritual realm that humanity would achieve when it evolved out of the material world, out of the biosphere — the “omega point” where humans would meet Christ. Vernadsky, an atheist and materialist (he called himself a “cosmic realist”) viewed the Noösphere as the part of the Biosphere that was being physically transformed by human activity. So it’s important, when the word appears, to determine which version the writer means, or if the writer is even aware of the deep difference.
Vernadsky’s most complete account of the Noösphere was a chapter in his unfinished book Scientific Thought as a Planetary Phenomenon. The new envelope, he wrote, began to take form with the invention of agriculture, which “radically transforms nature … clearing the land from other living organisms.”
You might say that within the last five to seven thousand years the continuous creation of the Noösphere has proceeded apace, ever increasing in tempo, and that the increase of the cultural biogeochemical energy of mankind is advancing steadily without fundamental regression, albeit with interruptions continually diminishing in duration. There is a growing understanding that this increase has no insurmountable limits, that it is an elemental geological process.(19)
Vernadsky strongly believed in evolution as an inevitable and progressive advance to a better future, that any negative side-effects caused by the expansion of the Noösphere would be overcome by human intelligence. It was already having positive social effects.
Profound social changes, giving support to the broad masses, advanced their interests into the first rank, and the question of eliminating malnutrition and famine, became a realistic option that can no longer be ignored.
The question of a planned unified activity for the mastery of nature and a just distribution of wealth associated with a consciousness of the unity and equality of all peoples, the unity of the noösphere, became the order of the day.(20)
In one of his last articles, one of the few published in English during his lifetime, he wrote that in modern times, human economic activity was literally changing the chemical composition of the biosphere.
That mineralogical rarity, native iron, is now being produced by the billions of tons. Native aluminum, which never before existed on our planet, is now produced in any quantity. The same is true with regard to the countless number of artificial chemical combinations (biogenic ‘cultural’ minerals) newly created on our planet. The number of such artificial minerals is constantly increasing. All of the strategic raw materials belong here. Chemically, the face of our planet, the biosphere, is being sharply changed by man.(21)
He described the Noosphere in terms that sound very like 21st century discussions of the Anthropocene.
Proceeding from the notion of the geological role of man, the geologist A. P. Pavlov [1854-1929] in the last years of his life used to speak of the anthropogenic era in which we now live … He rightly emphasized that man, under our very eyes, is becoming a mighty and ever-growing geological force … In the twentieth century, man, for the first time in the history of the earth, knew and embraced the whole biosphere, completed the geographic map of the planet Earth, and colonized its whole surface.(22)
The Noösphere would be “the last of many stages in the evolution of the biosphere in geological history.” For him, progressive geological evolution and the democratic fight against Nazi barbarism were related.
Now we live in the period of a new geological evolutionary change in the biosphere. We are entering the noösphere. This new elemental geological process is taking place at a stormy time, in the epoch of a destructive world war. But the important fact is that our democratic ideals are in tune with the elemental geological processes, with the laws of nature, and with the noösphere. Therefore we may face the future with confidence. It is in our hands. We will not let it go.(23)
There are obvious parallels between Vernadsky’s view that human activity was transforming the Biosphere into the Noösphere and the current view that human activity has so changed the Earth System that a new geological epoch has begun. His description of humanity’s impact on the biosphere could fit easily into any modern account of the disruption of profound disruption of biogeochemical cycles—in fact, of metabolic rifts.
Man always increases the number of atoms leaving the ancient cycles—the geochemical ‘eternal’ cycles. He intensifies the breach of these processes, introduces new ones, and interferes with old ones. With Man, an enormous geological power has appeared on the surface of our planet. The balance of the migrations of elements that had been established in the course of geological time is being broken by the reason and activities of Man. At present we are changing the thermodynamic equilibrium inside the biosphere in this way.(24)
We should not overstate the similarities. The research that defines Earth System science, including studies of global biogeochemical cycles, didn’t even begin until years after Vernadsky’s death. What’s more, as Clive Hamilton and Jacques Grinevald point out, he saw the Noösphere as the inevitable and progressive evolution of the Biosphere, while the Anthropocene represents “a very unwelcome rupture … a radical breakdown of any idea of advance to a higher stage.”(25)
More practically, Vernadsky’s influence on the development of Earth System science was limited because until recently his work was virtually unknown outside of the Soviet Union. When he died, fewer than half a dozen of his articles had been translated into English, and only a handful more into French or German. A full translation of The Biosphere wasn’t published until 1997. Even in the Soviet Union, most of his work was unavailable until the publication of his Selected Works in 1967.
In 1970, the influential magazine Scientific American published a special issue on the Biosphere, edited by George Evelyn Hutchinson, a Yale professor who is often called the father of modern ecology. His introductory article provided an overview of biospheric science, incorporating recent advances and fully crediting Vernadsky as originator of the field. He concluded by arguing that Vernadsky’s positive view of the Noösphere is difficult to maintain now that growing environmental crises are threatening the very survival of the Biosphere.
The Scientific American article generated new interest in Vernadsky’s work, but its impact was limited, particularly because so little of his work is available in languages other than Russian. Perhaps publishers and translators don’t think his thoroughly interdisciplinary works will sell in western academia, where geologists study geology and biologists study biology and the twain never meet. As Jacques Grineveld writes,
The revolutionary character of the Vernadskian science of the Biosphere was long hidden by the reductionist, overspecialized and compartmentalized scientific knowledge of our time.(26)
Although Vernadsky’s work didn’t directly influence the development of Earth System science, it remains important as an alternative materialist approach to understanding the relationships between life and planet. Seven decades after his death, Vernadsky’s insights into the nature and development of the biosphere can still illuminate our efforts to understand global metabolism—and global metabolic rifts.
