Cereals: production, energy and human and animal consumption
published: 26/07/22, 21:36
The majority of grain in the world is not consumed by humans.
The Economist newspaper did a series of infographics on cereal utilization around the world with 2019 data:
- Of the almost 3 billion tonnes produced in 2019, less than half (46%) is directly consumed by humans
- For the rest, a third (34%) is used in breeding as animal feed, 9% as biofuel, 2,5% as future seeds and the rest (8%) is lost in industrial processes.
- Since 2010, the use of cereals in the world has increased by 20 kg per person per year. Direct human consumption has not increased, while 17 kg of the 20 increase is attributed to livestock. 17kg of wheat provide 56 calories, enough to produce 000 baguettes.
- Yet animals are not effective: they waste between 60 and 97% of the calories from the cereals they are given, this is due to the intrinsic inefficiency of vegetable-to-meat conversion. So the best student is whole milk which wastes "only" 60% of the calories from cereals, while the worst student is cattle farming, which wastes 97% of the calories from cereals.
These figures are 78% for eggs, 88% for chickens and 90% for pigs.
"If the 750 million pigs were a country, it would be the largest grain consumer by far, consuming as much grain as 2 billion people."
The authors of the article conclude: "Ironically, one of the most effective ways for individual consumers to address the world's grain shortage is to eat more grains, at the expense of meat."
No kidding ?
