Recent years have seen significant progress in developing and validating alternatives to animal testing. New Approach Methodologies (NAMs)—including human cell models and advanced computer-based methods—can identify hazards faster, more cheaply, and often with results that are more relevant to humans than to laboratory animals. The U.S. Environmental Protection Agency has committed to eliminating all mammalian animal testing by 2035 and has expanded its list of approved alternative methods. However, while federal policy promotes reducing animal testing, no U.S. law currently mandates the use of validated non-animal alternatives when available. By contrast, the UK and EU require the use of non-animal methods when available.
The modern conversation surrounding animal protection is built on two distinct yet deeply intertwined pillars: animal welfare animal rights Sex bestiality zoo horse - Young Indian Woman with Horse.mpg
Peter Singer, an Australian moral philosopher, published Animal Liberation in 1975, a book widely credited with launching the modern animal rights movement. Singer's approach is utilitarian: he argues that a moral action is one that minimizes suffering or leads to the greatest happiness. Critically, Singer asserts that the capacity to suffer—sentience—rather than membership in the human race is the characteristic that entitles a being to equal consideration of its interests in the utilitarian calculation. Science has shown that all vertebrate animals (and at least some invertebrates) are sentient; they can suffer both physically and mentally and have an interest in not suffering. To fail to consider the interests of nonhuman animals is what Singer terms "speciesism"—a prejudice as irrational as racism or sexism. Recent years have seen significant progress in developing

Animals serve as models for human disease testing, toxicological screening, and psychological experimentation.
While often used interchangeably, welfare and rights represent two distinct philosophical approaches to the same goal: reducing suffering. Understanding Animal Welfare: The Standard of Care
