The largest breeding company in the United States is Charles River Breeding Laboratories(CRBL). It is headquartered in Massachusetts and owned by Bausch and Lomb. It commands between 40-50 percent of the market for mice, rats, guinea pigs, hamsters, gerbils, rhesus monkeys, imported primates, and miniature swine(PETA, campaigns). The University of Washington was the worlds largest monkey nursery, with 150 infants, which you can find in the Health Sciences basement. Baboons that carry backpacks to monitor stress are among 450 primates on the seventh floor. Infected monkeys on that floor are used to test Aids Drugs(Dietrich, A1). Since the University of Washington was unable to get a renewal grant for the federal government. It had to move more that 1,200 primates to Louisiana, Oregon and Seattle. Animal studies range from benign to unpleasant. They go from observing bird intelligence in aviaries to using pistons to crack the skulls of rats. This is used so that Harborview Medical Center researchers can learn to cope with human head traumas. Research animals are used to test drugs and vaccines, pioneer medical procedures, determine poisonous doses, indicate which products in animals might cause cancer, test cosmetics, toiletries and household cleaners. Animals are also used to study the behavior that ultimately influences human psychology. Much of the human benefit comes at a price to animals. For instance, an estimated 1-5 million monkeys died in the hunt for the oral polio vaccine. In the last few years there has been no shortage of horror stories about laboratory cruelties with dubious benefit. Thus resulting in a complex thicket of laws, regulations, and oversight committees(Dietrich, A1). .
In the 60's, Harlow isolated monkeys in cone shaped enclosures he theatrically called "pits of despair". The purpose of this particular experiment was to drive the monkey insane. This is only one of many examples of animal cruelty by scientists.
