The Factory Farm Waterworks

The system as one hydraulic works. Every channel width is a real, sourced quantity, so the argument is carried by geometry, not adjectives.
← back to the main site

Water enters at the left as 1,000 broiler chickens hatched and flows to the right. At every stage a spillway drains some away into a labelled waste basin. Header tanks above feed the works with grain, water, gas-made fertiliser and antibiotics. A money aqueduct runs alongside; externalised costs seep into the groundwater below. Storm clouds mark where the system is under pressure, and sluice gates on the far side show what could be diverted. Hover, tap, or tab to any figure for its number and source.

This works best on a wider screen, where the full channel is visible at once. On a phone the diagrams scroll sideways.
01

The main channel – the attrition funnel

Of 1,000 birds hatched, most clear every gate on the way to slaughter. The counter-intuitive truth the geometry reveals: the largest single leak is not on the farm or at the plant, it is the meat scraped off the plate at the very end.

Main channel:
live flow (birds still moving) drained to waste basin channel width ∝ head-count

Depth legend: 1 bird ≈ 0.22 px of channel height. The stage percentages come from different denominators (live birds for mortality and condemnation; carcass weight for retail and consumer loss), and the food-waste figures are US 2010 mass shares applied to the flow, not per-bird measurements. Widths are drawn strictly to the head-counts shown; nothing is exaggerated for effect.

02

Header tanks – what feeds the works

The system is an inefficient converter: it draws down a large share of the world's cropland, grain, water and pharmaceuticals and returns a modest fraction of human food. Each tank shows its own gauge in its own units; storm clouds mark the fragile inlets.

🌾 Feed reservoir

The biggest inlet. Two crops dominate the rations.

Global soy grown for animal feed77%11
US corn used as animal feed40%12

Corn is over 95% of US feed-grain use. Ethanol takes a further ~45%, but its distillers-grain co-products loop back into rations, so the two overlap.12

🌾 Feed-conversion loss

Kilograms of feed per kilogram of edible meat (Smil, edible-weight basis). These bars are strictly comparable.

🐄 Beef cattle25 : 113
🐷 Pig9.4 : 113
🐔 Chicken4.5 : 113

💧 Water tank

Green + blue + grey water footprint per kg. Beef is several times any other.

🐄 Beef, litres per kg15,415 L14

Pork and chicken are several times lower per kg; the dossier gives a firm figure only for beef, so no invented numbers are drawn for the others.

🟩 Fertiliser tank

Nitrogen fertiliser for feed crops is made from natural gas.

Gas as share of ammonia/urea cost~80%16

In 2022 this coupling snapped: the fertiliser price index hit an all-time high of 1,270.4.17 Russia is ~23% of ammonia exports.18

💉 Antibiotics tank

Livestock is the dominant driver of global antimicrobial use.

Global antibiotic tonnage to livestock~73%15

131,109 tonnes were consumed by food animals in 2013, projected to rise ~53% by 2030 – a key antimicrobial-resistance concern.15

The money aqueduct

Subsidies flow in, the retail dollar is captured mid-chain, and the costs the price never mentions seep into the groundwater below. Global meat is a market of roughly $1.4 trillion a year (commercial estimates vary).

Who captures the retail food dollar (2023)

15.9¢ post-farm marketing 84.1¢

Farm share by product: beef 41%, pork 26%.38

The chicken grower's cut

99.5% of US broilers (by value) are raised by contract growers paid under a "tournament" system, benchmarked against their neighbours. The median fee in 2020:

6.79¢/lb against retail chicken of several dollars a pound

Top four integrators control ~60% of the US market.41 Meanwhile compelled "checkoff" marketing funds pour back in: the Beef Checkoff alone approved ~$38m for FY2026.28

Subsidy inflow

EU farm subsidies (CAP) supporting animal products82%36

In the US, EWG tallied at least $72bn to livestock producers cumulatively over 1995–2023 (a multi-decade total, not annual).40 Feed is ~65–75% of a broiler's production cost, so feed-crop support is an indirect animal-ag subsidy.

Who owns the pumphouse

A handful of vertically integrated giants control the flow, and upstream an even tighter set of genetics firms controls the water source itself.

🍗 Big Four beef packers

US fed-cattle slaughter~85%2021

Up from ~25% in 1977. JBS (the world's largest, $77.2bn revenue22) listed on the NYSE in 2025; Cargill is the largest private US company (~$160bn23).

⚠ bottleneck

🥚 The broiler genetics duopoly

Two firms' global broiler-genetics share70–90%19

A single German family holding (EW Group / Aviagen, ~44% alone) and one US meat conglomerate (Tyson / Cobb) sit atop the entire world's chicken gene pool.

🏛 Levers that already moved

California's Proposition 12 (sow/hen/veal confinement minimums) was upheld 5–4 by the US Supreme Court in May 2023.24

Over 3,000 companies have pledged cage-free; the Good Food Institute (~$16m budget) works alternative proteins.

05

Demand – the pressure at the tap

These are figures for meat supply per person (carcass weight), which runs above what is actually eaten. Bars are strictly comparable within the chart.

Meat supply per person, 2023 (kg/year, excluding fish)

The defining story is China: from 3.4 kg in 1961 to 73.5 kg in 2023, a roughly twenty-fold rise. World output already tops 350 million tonnes a year and FAO projects ~455 Mt by 2050.26

Demand is moderately inelastic: a 10% price rise cuts consumption only ~7% (own-price elasticity beef −0.75, pork −0.72, poultry −0.68).27

06

Storm clouds – pressure over the reservoirs

Dense monocultures of genetically uniform animals are fragile to the very forces the system accelerates. Each cloud sits over the part of the works it threatens.

FAO's long-run scenario puts 2050 output ~50% above 2012, poultry supplying most of the growth.26 India and Southeast Asia replace China as the engine.

Sluice gates – what could be diverted

On the far side of the works, gates and diversion channels show reforms that are technically feasible and already market-tested where mandated. Each shows what it diverts.

welfare technology

In-ovo sexing

diverts the ~7 billion male chicks culled yearly34

Germany (2022) and France (2023) banned chick culling; 28% of EU hens are now sexed in-ovo, at under one euro-cent extra per egg.

Replaces conscious live-shackle slaughter. Perdue, Tyson pilots and a McDonald's sourcing pledge have driven partial US adoption.

Better Chicken Commitment

200+ companies on slower breeds & lower density35

Slower-growing breeds cut on-farm mortality (3.2% conventional vs 1.9% slow-growth). Enforcement is uneven.
