Soylent Green (*Soylent Green*, Richard Fleischer, 1973)

What it is

Soylent Green is a food product — a small, green wafer produced by the Soylent Corporation — distributed to the population of an overcrowded, resource-depleted 2022 New York City as a nutritious and affordable food source. It is advertised as being made from "high-energy plankton." It is not made from high-energy plankton. It is made from people. This is the revelation at the center of one of science fiction cinema's most iconic single lines of dialogue, delivered by Charlton Heston as Detective Robert Thorn in a full-throated scream at the film's conclusion: "Soylent Green is people!"

The horror of Soylent Green is not the horror of primitive cannibalism. It is the horror of industrial efficiency applied to a human ethics problem and producing a monstrous but internally coherent solution. The people who created Soylent Green are not monsters in the conventional sense. They are technocrats who identified a resource problem (too many people, too little food, an ecosystem that has collapsed to the point where it can no longer feed everyone) and solved it with the most efficient available input (the people who are dying anyway, in a society where death by euthanasia — "going home" — is presented as a mercy). The horror is the logic. The horror is how reasonable it all sounds from inside the system.

The source work

Soylent Green (1973), directed by Richard Fleischer. Screenplay by Stanley R. Greenberg, based on Harry Harrison's 1966 novel Make Room! Make Room! — though Harrison's novel does not include the cannibalism revelation. In Harrison's book, the food crisis is real and the food products (Soylent steaks and similar) are genuinely made from soybeans and lentils (Sol-Lent — the name is a portmanteau). The cannibalism was a screenplay addition by Greenberg, and it transformed a competent ecological science fiction novel into something mythologically durable.

How it's described

The film's New York of 2022 is presented as a city of approximately forty million people in a state of perpetual, managed suffering. The streets are carpeted with homeless people. Food riots erupt regularly. The wealthy live in fortified apartments with security guards and actual vegetables — unthinkably luxurious items in this world. Real food — a jar of strawberry jam, a piece of celery, a slab of beef — is so rare that it functions as currency, as status symbol, as sacrament.

The food system that feeds most people runs on three Soylent products:

Soylent Red: A cracker or wafer in red, presumably made from some protein source. It is rationed and distributed in weekly allocations. It is adequate.

Soylent Yellow: The yellow equivalent. Also adequate. Neither Red nor Yellow receives much narrative attention because they are not the point.

Soylent Green: The new product — just released, still in limited supply, the subject of intense demand. Soylent Green is presented as superior to Red and Yellow: more nutritious, better tasting (presumably), more satisfying. People queue for it. The queues themselves become crisis flashpoints. The scarcity of the "good" Soylent even within a world of scarcity is a pointed detail: even in the most dystopian resource distribution system, there is still a premium tier. Even when everyone is eating wafers made from the dead, some wafers are marketed as better than others.

Detective Thorn investigates the murder of a Soylent Corporation board member and gradually uncovers the secret: the corporation disposes of human bodies from the government-facilitated euthanasia program (called "going home") by processing them into the Soylent Green formula. The government knows. The corporation knows. The supply chain is managed efficiently. The horror is not that someone evil did something. The horror is that the whole system did it, collectively, and everyone who needed to know was told not to know.

Real-world basis

The film's ecological projections for 2022 were, in 2022, both more accurate than the filmmakers might have hoped and less accurate than climate scientists feared:

The accurate parts: The film correctly identified the trajectory of global temperature rise, urban overcrowding in megacities, ecosystem collapse affecting food systems, mass extinction of marine species, and the widening gap between what wealthy and poor people could afford to eat. When the film was released in 1973, these were alarming extrapolations. By 2022, they were the front page of any newspaper on any given week.

The less accurate parts: New York in 2022 did not have forty million people. The specific form of collapse the film predicted — total ecosystem failure by 2022 — did not occur on that schedule. The film's timeline was wrong, as fictional timelines usually are. The direction it was pointing was not.

The food system critique: The film's most pointed observation is not about cannibalism. It is about what happens when a food system becomes fully industrialized and fully opaque. When you cannot see what is in your food, you are dependent on the honesty of the system that produces it. The industrialized food system of the real 2022 — with its complex global supply chains, its processed food industry, its opacity about ingredients, its regulatory capture by the corporations it regulates — is not producing Soylent Green. But the structural conditions that make Soylent Green possible in the film — a population that has ceded knowledge of its food supply to corporate management, a regulatory system that has been compromised, a government that has made a calculation that some people don't need to know certain things — those conditions are genuinely present in the real food system.

The horsemeat scandal of 2013, in which products labeled as beef across Europe were found to contain undisclosed horse meat, was not Soylent Green. But it demonstrated, on a small scale, exactly the dynamic the film is describing: that when food processing is sufficiently complex and sufficiently concentrated in large corporations, the people eating the food lose meaningful ability to know what they are eating, and the companies know this and sometimes exploit it.

The euthanasia-resource link: The film's darkest specific prediction is the managed euthanasia system — "going home" facilities where people are encouraged (gently pressured) to end their lives when they become a resource burden, then processed into food. This is not a reality in 2026. But the connection the film draws between resource scarcity, population management, and the calculus of which lives are worth the resources they consume is a genuine ongoing political tension. Debates about end-of-life care, assisted dying legislation, and the economics of healthcare for elderly populations involve exactly the question the film is raising: in a world of finite resources, who gets to decide whose consumption of those resources is justified, and what do we do with the answer?

The Soylent Drink Company: The Audacity of the Name

In 2013, a 24-year-old software engineer named Rob Rhinehart launched a Kickstarter campaign for a meal replacement drink he was calling Soylent. He named it after the film deliberately. He knew exactly what he was doing, and the cultural response — a mixture of disgust, dark humor, and genuine curiosity — was exactly what he was counting on.

Rhinehart's argument was straightforward and, in its way, idealistic: food preparation is inefficient and time-consuming; most people don't actually enjoy most of the meals they eat most of the time; a nutritionally complete, affordable, shelf-stable liquid food could be a genuine solution to both food insecurity and the opportunity cost of cooking. Soylent (the product) contains a complete protein blend, carbohydrates from oats and maltodextrin, fats, and a comprehensive vitamin and mineral package. It is drinkable. It is beige. It is, by most accounts of people who have tried it, mildly pleasant or neutral in flavor. It is not people.

The company's marketing from the beginning leaned into the film reference with a winking directness that managed to be both brave and slightly off-putting. The implicit message was: "We know what you're thinking. The name is a joke. But the product is not a joke, and maybe the reason you find the idea of meal replacement unsettling is worth examining." Whether this was genius or bad taste or both, it worked: Soylent attracted significant investment and media coverage, and as of 2026 remains in business as a commercially available product with a dedicated user base primarily among tech workers and people who find cooking genuinely burdensome.

The cultural response to Soylent (the company) is itself a data point about the film's legacy. The name generated instant recognition forty years after the film's release. "Soylent Green is people" had become one of those cultural phrases that exist independent of direct knowledge of the source — like "Big Brother" or "Catch-22," known by people who have never seen the film. The company appropriated this recognition brilliantly: they got massive free publicity because "startup names itself after cannibalism film" is an automatically interesting story, and the product itself was substantively different enough from the film's product to make the joke land rather than appall.

There is also a genuine intellectual engagement with the film buried in the Soylent product. Rhinehart's stated goal — to create a food system that is more efficient, more transparent about its nutritional content, and less dependent on the complex and often exploitative supply chains of conventional food — is, in a sideways sense, an attempt to solve the problem that the film's world failed to solve. If you can feed people nutritiously and affordably from a fully disclosed and ethically produced formula, you reduce the pressure that leads fictional technocrats to make monstrous decisions. The joke name contains a genuine engagement with the film's argument.

The Horror Logic: Why Industrialized Cannibalism Is More Disturbing Than the Other Kind

The specific contribution of Soylent Green to the resource allegory genre is this: it identifies that the most frightening version of any atrocity is the managed, bureaucratic, normalized version. Premodern cannibalism appears in mythology and historical record as a crisis behavior — something done by people in extremis, in famine conditions, as an act of desperation that the perpetrators usually recognize as transgressive. The horror is acute but it is comprehensible.

The Soylent Green system is something different. It is cannibalism that has been absorbed into the regulatory apparatus, assigned a permit number, integrated into the supply chain, and presented to the consumer as a product benefit ("high-energy plankton!"). The people who run it are not experiencing it as cannibalism. They are experiencing it as a resource management solution. The atrocity has been processed into something indistinguishable from ordinary corporate activity, and that processing is the horror.

This is the same insight that Hannah Arendt identified in Eichmann in Jerusalem (1963, two years before Soylent Green's source novel) — that the most effective evil is not cackling villainy but bureaucratic normality, that atrocity at scale requires not monsters but functionaries who do not have to look at what they are enabling. The Soylent Corporation is Eichmann's logic applied to food. The horror of the revelation is not just "this food is made of people" but "this food is made of people and the system is working exactly as designed."

Cultural legacy

"Soylent Green is people" has achieved a cultural permanence out of proportion to its film's artistic reputation. The phrase functions as a shorthand for any revelation that a comfortable system is built on something hidden and horrifying. It has been applied, in journalism and popular culture, to meat processing exposés, pharmaceutical industry critiques, social media platform analyses (the product is the user), gig economy labor conditions, and any other context where the question is "but what is this really made of, and who is paying the hidden cost?"

The real achievement of Soylent Green as a cultural artifact is that it made "what is this food really made of?" into a question with moral urgency. Before the film, that question was primarily a nutritional concern. After it, the question acquired a political and ethical dimension: who decides what goes into mass food products, who knows, who is told not to know, and whose body is the ultimate input into the system?

Reference notes

• Soybeans — the "Sol" in the original Sol-Lent portmanteau; soybeans are the most significant source of mass-produced protein globally and the actual basis of many real meal replacement products
• Lentils — the "Lent" in Sol-Lent; one of the oldest cultivated legumes; a primary protein source in global food security contexts
• Protein powders and meal replacements — the real-world category that Soylent (the company) inhabits; connects to athletic nutrition, food security, and the ethics of food industrialization
• Plankton and sea vegetables — the cover story the Soylent Corporation tells; connects to real emerging food technologies around algae-based proteins (spirulina, chlorella) as sustainable food sources
• Insect protein — not in the film, but the logical next step in the "sustainable protein from unconventional sources" trajectory the film identifies; see also Snowpiercer entry below
