DirectionalPain and Euthanasia Rates Interpretation
If these statistics were presented not as sterile data but as the living conditions for the victims they describe, we would recognize a sprawling, taxpayer-funded dystopia where the baseline unit of scientific currency is protracted and often unrelieved animal agony.
