Efficiency of food production

The efficiency of food production can be improved by reducing the amount of energy lost to the surroundings. This can be done by:

  • preventing animals moving around too much
  • keeping their surroundings warm

Mammals and birds maintain a constant body temperature using energy released by respiration. As a result, their energy losses are high. Keeping pigs and chickens in warm sheds with little space to move around allows more efficient food production. But this raises moral concerns about the lives of…
