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.
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.
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.
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.
Green + blue + grey water footprint per kg. Beef is several times any other.
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.
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).
Farm share by product: beef 41%, pork 26%.38
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:
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
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.
A handful of vertically integrated giants control the flow, and upstream an even tighter set of genetics firms controls the water source itself.
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).
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.
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.
These are figures for meat supply per person (carcass weight), which runs above what is actually eaten. Bars are strictly comparable within the chart.
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
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.
Killed since February 2022, the worst US outbreak on record.29 Culls drove eggs to a record $6.23/dozen in March 2025.30 In 2024 H5N1 spilled into 800+ dairy herds with ~58 human cases – a pandemic-preparedness flag.
Projected global cattle heat-stress losses by 2100 under high emissions.31 Livestock both drive warming and are its victims; India could lose >45% of dairy output.
The fertiliser price index hit an all-time high in March 2022 after Russia's invasion.17 US anhydrous ammonia nearly quadrupled from ~$487 to ~$1,500 a ton.
Killed or culled in China in 2018–19, halving the national herd, with losses near $141bn.32 One pathogen can crater a system built on dense, homogeneous herds.
Denmark is the first country to tax livestock methane, from 2030.33 The Global Methane Pledge (~155 countries) targets a 30% cut by 2030.
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.
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.
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.
Slower-growing breeds cut on-farm mortality (3.2% conventional vs 1.9% slow-growth). Enforcement is uneven.
Denmark's methane tax, Prop 12, and the Good Food Institute's alternative-protein work all divert flow away from the worst of the system.
