① To paraphrase 18th-century statesman Edmund Burke, “all that is needed for the triumph of a misguided cause is that good people do nothing.” ② One such cause now seeks to end biomedical research because of the theory that animals have rights ruling out their use in research. ③ Scientists need to respond forcefully to animal rights advocates, whose arguments are confusing the public and thereby threatening advances in health knowledge and care. ④ Leaders of the animal rights movement target biomedical research because it depends on public funding, and few people understand the process of health care research. ⑤ Hearing allegations of cruelty to animals in research settings, many are perplexed that anyone would deliberately harm an animal.
