Factory floor
A single production line: fossil gas and feed crops in at the left, a plate at the right. The red โ on a building marks a market controlled by a handful of firms. Belts run left to right; some cargo never makes it.
Attrition funnel: 1,000 broiler chickens
Follow 1,000 chickens hatched for meat. Units drop off the belt into loss bins at each stage. The largest leak is not on the farm, it is the food scraped off the plate.9
Percentages use different denominators (live birds vs inspected weight vs total food mass), so they are stacked for legibility, not summed. On-farm and slaughter losses are small; retail and consumer waste dominate.
