10.Now, consider ratios of animals killed to protein produced. For lack of a better term, you can calculate a relative ‘efficiency’ rating using these numbers. The lower the number, the greater the efficiency of the farming method. In plain English, this amounts to saying that the method with smaller numbers in the second column is less costly in lives per unit of protein:
- at least 25 times more sentient animals being killed per kilogram of useable protein
- more environmental damage, and
- a great deal more animal cruelty than does farming red meat.
