Pre-packaged foodstuffs compliments of oil industry, not Greens political spin and rhetoric

By Harry Richardson

Walk through a modern supermarket for a moment and look carefully.

Rows of fruit in perfect colour. Meat sealed in tidy packages. Bread stacked in quiet abundance. Freezers full of meals from cuisines most people would not have recognised two generations ago. Forty thousand products under bright lights, available seven days a week.

It is one of the quiet miracles of modern civilisation.

We rarely think about it anymore.

But the abundance resting on those shelves depends on something most shoppers never see.

Oil.

Not metaphorically. Literally.

Modern food is, in a very real sense, rearranged petroleum.

For most of human history, agriculture ran on three energy sources: sunlight, human muscle, and animal muscle.

A farm in medieval Europe was essentially a solar energy system. Crops captured sunlight through photosynthesis. Animals converted those crops into labour. Humans organised the work and hoped the weather cooperated.

Productivity was low. Harvests were uncertain. Entire communities could be pushed into crisis by a single failed season.

Agriculture produced food, but it did so slowly and precariously. Then fossil fuels entered the field.

The first transformation was mechanical. Horses and oxen gave way to tractors. Irrigation pumps driven by diesel replaced the limits of rainfall. Mechanical harvesters replaced large armies of seasonal labour.

The scale of farming expanded dramatically. One farmer who once fed a household could now feed a village. In many modern economies, a single farmer produces enough food to sustain more than a hundred people.

Cheap energy did not simply transform industry. It transformed the farm.

The deeper revolution, however, came from chemistry.

Modern agriculture depends heavily on nitrogen fertiliser produced through the Haber–Bosch process. The chemistry itself pulls nitrogen from the air and converts it into ammonia that crops can absorb. But the process requires enormous energy inputs, and those inputs come overwhelmingly from natural gas.

The result is a quiet but extraordinary fact. A substantial share of the world’s food supply is effectively produced by the natural gas industry.

Estimates vary, but many researchers suggest that roughly half of the global population is fed by crops grown using synthetic fertiliser.

The Green Revolution was not purely agricultural. It was petrochemical.

Modern farming is therefore not simply a biological activity taking place in fields. It is part of a much larger industrial system.

Tractors the size of small houses cultivate land using satellite guidance. Diesel pumps draw water from deep aquifers. Fertiliser factories operate hundreds or thousands of kilometres away from the farms that depend on their output.

A medieval farmer needed a plough and a horse. A modern farmer requires diesel deliveries, replacement parts manufactured in global supply chains, fertiliser plants powered by natural gas, and transport systems capable of moving enormous volumes of crops across continents.

The farm has become an industrial site that happens to grow plants.

And industry runs on energy.

Now widen the lens beyond the farm itself.

Modern food systems assume that distance is cheap.

Beef travels from Brazil to European markets. Soy grown in Argentina feeds livestock in China. Apples harvested in New Zealand appear in northern supermarkets long after local orchards have gone dormant.

In the late nineteenth century, refrigeration changed the meaning of distance in food. Before that, meat was either eaten locally or preserved by being salted, dried, or smoked. Freshness did not travel. The breakthrough came with mechanical refrigeration and the first successful refrigerated shipping lines, which allowed frozen and chilled meat from Australia and New Zealand to reach British markets in usable condition. That was not just a commercial innovation. It was a sanitary one. Cold did what distance and time had always undone: it slowed bacterial growth, stabilised food, and made it possible to handle, store, and transport perishable goods without rapid spoilage. Modern food safety, the expectation that meat can sit in a cabinet for days without becoming dangerous, rests on that cold chain.

But refrigeration is not an independent system. It is an energy system. From the earliest ammonia compressors driven by coal-fired engines to modern refrigerated containers powered by diesel generators and electricity grids, the cold chain has always depended on abundant, continuous energy. Every refrigerated warehouse, every supermarket freezer, every chilled truck is a small, ongoing claim on the same underlying fuel base. Remove that energy, and refrigeration does not degrade gracefully. It stops.

The global food system is not merely agriculture. It is a vast logistical network that spans the planet. Container ships move grain across oceans. Refrigerated trucks distribute food across national highway systems. Fertiliser travels thousands of kilometres before it ever reaches a field. Oil made those distances economically manageable. In effect, cheap energy turned the world into one interconnected farm.

But distance has a way of returning when the cost of energy rises.

Even inside the supermarket itself, the system depends on speed rather than stockpiles. Most stores hold only a few days’ worth of inventory. This is not recklessness. It is the logical outcome of a supply chain optimised for efficiency. Food moves continuously through a chain that rarely stops. It moves from farm to processor, from processor to distributor, and from distributor to supermarket. Efficiency keeps prices low and shelves full. It also removes the buffers that once protected the system from disruption. When the flow slows, the shelves empty quickly.

Efficiency is a remarkable achievement. But it is not the same thing as resilience.

One way to understand the transformation of agriculture is through the language of energy. Traditional farming largely ran on solar income. Industrial farming runs on sunlight organised by fossil fuels. Fertiliser production requires natural gas. Farm machinery consumes diesel. Food processing, refrigeration, packaging, and long-distance transport all draw energy from the same industrial system.

And this is where the present moment stops being abstract. In the past few days, the war in the Middle East has moved beyond threats to actual damage. Iran’s strike on Qatar’s Ras Laffan complex has knocked out roughly 17 per cent of Qatar’s LNG export capacity, with two LNG trains reportedly damaged badly enough to be offline for years. Before that, Israel struck Iran’s South Pars gas field and the Asaluyeh processing hub attached to it. Trump then warned Iran against any repeat strike on Qatar, while reports elsewhere described an explicit threat against the rest of South Pars. This is not diplomatic theatre. It is the targeting of the machinery that keeps global energy moving.

That matters because modern agriculture is downstream from all of it. Natural gas is not just something that heats homes. It is the feedstock for fertiliser. When LNG capacity is destroyed, when gas fields are hit, when shipping risks rise, and cargoes are redirected, fertiliser costs move with them. Oil does the same work elsewhere in the system. It powers farm machinery, road freight, shipping, and cold storage. What begins as a strike on energy infrastructure quickly becomes a rise in the cost of producing food.

You can see it already, in small ways. A few cents more at the bowser. A missing brand on a supermarket shelf. Nothing dramatic. Nothing that looks like a crisis.

That is how these things begin.

But take the worst-case scenario seriously for a moment. Not as a thought experiment, but as a baseline.

Australia sits in an especially brittle position. It exports enormous volumes of LNG, yet the infrastructure to direct it locally quickly does not exist. And LNG is not a substitute for oil.

Petrol stations run dry first. Panic buying will empty the system even before the boats stop arriving.

No fuel, no logistics. No logistics, no supermarkets. It is a brutally simple chain.

The initial shock is psychological as much as physical. Households do not wait for empty shelves. They anticipate them. They buy early, buy more, and strip the system of its buffer. What looked like a supply problem becomes a behaviour problem, which then becomes a real supply problem.

It’s an unstoppable feedback loop once confidence disappears.

After that first shock, the deeper damage begins.

Fertiliser supply tightens hard enough that farmers pull back immediately, not cautiously. Application rates drop across an entire planting cycle. That decision is invisible to most people at the time. Fields still look the same. Tractors still move.

But agriculture runs on delayed consequences. What is not put into the soil now is not harvested later.

At the same time, diesel, if available at all, becomes scarce enough to change behaviour. Marginal land is not planted. Harvesting decisions become selective. Transport begins to falter across a continent where distance is not an inconvenience but a governing reality.

Distance itself becomes an enemy.

Imported food does not provide relief. It simply does not arrive as global supply tightens and other countries begin quietly, then openly, protecting their own populations. Export restrictions appear first as temporary measures, then harden into policy.

Australia is not immune to that logic. It participates in it.

So the system does not collapse in a single dramatic moment. It degrades in layers.

First, the servos become unreliable. Then the shelves become inconsistent. Then the prices become prohibitive.

Abundance does not disappear. It thins. Variety goes first. Then affordability. Then trust. And once trust goes, everything accelerates.

People do not shop for what they need. They shop for what they fear they will not be able to get tomorrow. Businesses hold inventory rather than sell it. Governments intervene with price controls here, export restrictions there, usually just enough to distort signals without restoring stability.

Everyone begins acting as if scarcity is inevitable. That’s how it becomes so, even before the physical logistics make it so.

The modern world did not solve food security. It outsourced it to energy and logistics, then built a culture that forgot the dependency. No supply lines, no abundance.

For a long time, those supply lines were so stable they became invisible. Supermarkets looked like systems of production rather than systems of distribution. It felt as though food simply existed.

But it does not simply exist. It has to be moved.

And if the movement stops, if gas fields burn, if LNG trains go offline, if oil does not come in or go out, then what Australia faces is famine.

Not a theatrical collapse on day one, but a fast-moving unravelling.

Shelves empty, then stay empty. Distribution breaks, then cannot be restored. Production falls, then fails to recover. A country with food somewhere, but not where people are.

Since World War II, politicians have been able to manage crises rhetorically. They rely on spin and process. They will believe that it will work again, just as it always has.

Until it doesn’t.
