An 18th-century statesman Edmund Burke once said, “All that is needed for the success of a misguided cause is that good people do nothing.” One such cause now seeks to end biomedical research because of the theory that animals have rights to decide whether to be used in research. Scientists need to respond forcefully to animal rights advocates, whose arguments are puzzling the public and threatening advances in health knowledge and care. Leaders of the animal rights movement attack biomedical research because it depends on public funding, and few people understand the process of health care research. Hearing false reports of cruelty to animals in research settings, many are puzzled that anyone would harm an animal on purpose.
For example, a grandmotherly woman setting up an animal rights booth at a recent street fair was giving out sheets that encouraged readers not to use anything that comes from or is tested in animals－no meat, no fur, no medicines. Asked what will happen when epidemics(传染病) return, she said. “Don’t worry, scientists will find some way of using computers.” Such well-meaning people just don’t understand.
Scientists must communicate their message to the public in an understandable way－in human terms, not in the language of biology. We need to make clear the connection between animal research and a grandmother’s organ replacement, a father’s bypass operation, a baby’s vaccinations(接种疫苗), and even a pet’s shots. To those who know nothing about the animal research that was needed to produce these treatments, as well as new treatments and vaccines, animal research seems wasteful at best and cruel at worst.
Much can be done. Scientists could give middle school lessons and present their own research. They should be quick to respond to letters to the editor, in case animal rights misinformation goes unchallenged and gains a false appearance of truth. Research institutions could be opened to tours, to show that laboratory animals receive humane care. Finally, because there are a lot of patients, the health research community should actively recruit(招募) not only well-known personalities such as Stephen Cooper, who has made courageous statements about the value of animal research, but all who receive medical treatment. If good people do nothing, there is a real possibility that uninformed citizens will wipe out the precious of medical progress.
