Acharya Prashant explains that animal testing in the pharmaceutical industry is not a technical necessity but a choice driven by cost-effectiveness. He points out that while modern computing power and simulations can replace animal trials, the lack of compassion and investment prevents this shift. He suggests that the transition to cruelty-free medicine requires a strong collective resolve from consumers. If people demand vegan alternatives and refuse products involving animal suffering, the profit-driven pharmaceutical industry will be forced to adapt and provide ethical options. The speaker highlights the role of doctors in this change, advising them to prioritize medicines with minimal animal cruelty and communicate these preferences to pharmaceutical representatives. He reflects on the historical use of animal parts in primitive medicine, describing it as a sign of a dark age and a lack of spiritual or scientific maturity. He asserts that as humanity becomes more spiritually aware and scientifically advanced, these barbaric practices will eventually be abolished. He envisions a future where the current methods of testing on animals will be seen as an unbelievable and primitive part of human history.
