PROFETAS: The production of animal proteins is inefficient

During the last forty years, the supply of animal proteins has steadily increased from 7 kg to 10 kg per person globally (by comparison, animal protein supply in the European Union has reached the point of saturation at 20 to 27 kg!). During the same period, the total supply of animal protein production more than doubled from 25 billion kg to 60 billion kg due to the increased number of people.

The production of animal proteins is inefficient: 2 to 15 kg of plant foods are required to produce 1 kg of animal products. Presently, 40-50% of the global cereals harvest is used to feed the animals and satisfy the demand for their products. In theory, a reduction of animal proteins in high income diets would reduce such inefficient use of grains and spare the resources (land, water, nitrogen) required for their production and would thus be more sustainable...
