Late last month, the New York Times reported that researchers used monkeys to test the effects of inhaling diesel fumes from a Volkswagen. The research was commissioned by the European Research Group on Environment and Health in the Transport Sector, an organization funded by three big German car manufacturers: Volkswagen, Daimler and BMW.
The reaction to this revelation has been unequivocal repudiation – by the public, the German government and Volkswagen itself – of the use of the monkeys for these tests. Why? Could the vehemence of the response indicate a tectonic shift in ethical attitudes toward animals? To answer that question requires examining some details about the experiments and the reaction to them.
The research, carried out in in Albuquerque, New Mexico, involved placing 10 monkeys in small airtight containers into which, over a period of four hours, the exhaust fumes were piped. Later, a tube was stuck down the monkeys’ throats to take tissue samples from their lungs.
I have never seen such categorical repudiation of experiments on animals as we are now witnessing in Germany.
It is clear that the experiments were extremely distressing for the monkeys. The Guide for the Care and Use of Laboratory Animals, a manual of good practice for those who use animals in research – published by the US National Academies of Sciences, Engineering, and Medicine and now in its eighth edition – states: “Like all social animals, nonhuman primates should normally have social housing.” These monkeys were confined in individual chambers and forced to breathe polluted air, including exhaust fumes from an older Ford truck, which was supposed to enable a comparison with the cleaner Volkswagen. A video of the experiments included in the Netflix documentary “Dirty Money” shows a monkey in a state of panic, pawing at the window of the chamber in a desperate effort to escape.
[Editor’s note: VW has since denied the video was from the original experiments, saying they were reconstructions for the documentary.]
Making matters worse, we now know that the only results the experiments could have yielded would have been misleading. Unknown to Jake McDonald, the scientist who oversaw the research, the Volkswagen vehicle that was used to produce the exhaust gases had software installed that reduced emissions under laboratory testing conditions, so the results could not provide reliable information on the health hazards of the car’s emissions during normal driving. No wonder Mr. McDonald told the New York Times, “I feel like a chump.”
The reaction to news of the research was swift. Two days after the story broke, Volkswagen tweeted that it “explicitly distances itself from all forms of animal cruelty. Animal testing contradicts our own ethical standards.”
Over the next two days, criticism mounted. At a meeting in Brussels, Volkswagen CEO Matthias Müller addressed the experiments, saying that the European Research Group’s methods were “totally wrong.” He added: “There are things you just do not do.” Thomas Steg, Volkswagen’s chief lobbyist, told a German newspaper: “We want to absolutely rule out testing on animals in the future so that this doesn’t happen again.” This didn’t help Steg himself, whom Volkswagen promptly suspended.
The other funders of the European Research Group quickly distanced themselves from the experiment. Daimler said that it was “appalled” by the studies, and would investigate them. BMW said that it didn’t participate in the research. Representatives of General Motors, Ford and Fiat Chrysler said that they do not test the effects of emissions on humans or animals.
The public response to the experiments reached a level that even the German government could not ignore. Steffen Seibert, a spokesperson for Chancellor Angela Merkel, said that, “the disgust many people are feeling is absolutely understandable,” and that the tests on monkeys “can in no way be ethically justified.”
I have been arguing against the way we treat animals for the past 45 years, yet I have never seen such categorical repudiation of experiments on animals by senior corporate executives and government spokespeople as we are now witnessing in Germany. If the reactions had condemned Volkswagen for seeking to mislead the public by supplying the researchers with a rigged car, I would not have been surprised. But Volkswagen’s use of “defeat devices” in its cars to cheat on emissions tests has been known since 2015. It is the abuse of the monkeys that is driving the condemnations, and the desire of the companies to distance themselves from the research.
A 2015 Gallup poll showed 89 percent of respondents in Germany opposed animal testing that causes pain and suffering.
It isn’t news that animals suffer in painful and unnecessary experiments. In every edition of Animal Liberation since the original in 1975, I described dozens of experiments in which the suffering of animals was severe and the likelihood of any significant benefit to human health or well-being was as remote as it was in the Volkswagen experiments. Today, organizations like People for the Ethical Treatment of Animals, or Peta (see photo above), continue to highlight how millions of animals, including monkeys, suffer in unnecessary experiments.
Nearly 3 million animals are used in experiments in Germany each year. If Volkswagen, Daimler, BMW and the German government are saying that experiments like those commissioned by the European Research Group to test the health impact of diesel exhaust are unethical, then many other experiments also fail to meet the same ethical standard.
What has changed, gradually and over several decades, is concern for animals. A 2015 Gallup poll showed that almost one in three Americans agreed with the statement that animals should be given the same rights as people, while nearly all the rest (62 percent) thought that animals should be given some protection. In Germany, 89 percent of those polled said that they oppose animal testing that causes pain and suffering. In several other European nations, including France, Italy and the United Kingdom, opposition was also above 80 percent.
No car manufacturer or other corporation that values its brand can afford to alienate 80 percent of its potential customers. If using monkeys to test the safety of emissions from diesel engines is ethically indefensible, it becomes possible to hope that the end to painful experiments on animals isn’t far off.
