Modern animal welfare science goes beyond preventing suffering to actively promoting positive experiences. The concept of positive welfare recognizes that animals can thrive, not merely survive.
The shift from negative welfare (freedom from suffering) to positive welfare (promotion of positive experiences) represents a maturation of animal welfare science. Animals do not merely need to avoid pain and fear; they benefit from opportunities for play, exploration, social bonding, and mastery. Positive welfare frameworks require richer assessments of animal lives and more demanding standards for housing and care. This evolution improves both the science and ethics of animal welfare.
