The scientific community increasingly embraces the 3Rs principle : Replacement (using non-animal models like organs-on-a-chip), Reduction (using fewer animals), and Refinement (minimizing pain and distress through better anesthesia or housing). Entertainment and Tourism

Should we expand on or historical milestones ?

: This movement rejects the property status of animals. It argues that animals have inherent value and deserve fundamental legal protections, such as the right not to be killed or used as resources.

A science-based approach focused on the humane treatment of animals under human control. It does not necessarily oppose the use of animals for food, research, or entertainment, provided they are kept in conditions that minimize suffering and satisfy their biological and behavioral needs. Key frameworks include the "Five Freedoms" (freedom from hunger, discomfort, pain, fear, and to express natural behavior).

Mammals, birds, and increasingly recognized organisms like cephalopods (octopuses) and decapod crustaceans (crabs and lobsters) possess sentience. This means they can experience positive and negative emotional states, including joy, affection, fear, anxiety, and physical pain. Studies show that pigs can play video games, crows can manufacture tools, and elephants mourn their dead. This growing body of evidence forces society to expand its circle of moral consideration. Critical Frontiers in Animal Advocacy

(ensuring conditions and treatment which avoid mental suffering).

Ethical arguments are increasingly reinforced by economic and environmental realities. Industrial livestock farming is a primary driver of deforestation, biodiversity loss, and greenhouse gas emissions. Furthermore, the overuse of antibiotics in animal farming accelerates global antimicrobial resistance risks.
