This document discusses the moral implications of animal testing. It notes that over 1 million animals are used for research in the United States each year, and these animals experience pain, suffering, and stressful conditions. While animal testing has led to discoveries like penicillin and HIV/AIDS medications, it can also be wasteful and involve euthanizing animals. The document proposes following the 3Rs strategy - reduction, refinement, and replacement of animal testing, with alternative measures like computer software and microorganism studies. It concludes that in scientific research, we hope to gain knowledge through productive and respectful experiments while recognizing animals cannot consent, and we should seek to phase out animal testing.
