Good for you!
Then these laws will not affect your research, or that of all the other biologists who have kept pace with technology, huh? They would probably only affect that small percentage of repetitious experimental work that is done by corporations seeking approval for new cosmetics, food additives, clothing treatments, and so on. What would that be? Only 90% of all the research that is being done today?
According to USDA, there were 1.1 million animals used in research in 2010 (the latest year of data). However although it breaks out dogs, cats, hamsters, and guinea pigs separately, it excludes the most common lab animals: rats and mice. It most certainly under reports in other areas, since the data are acquired only on the research that the USDA has responsibility for. Research on testing the efficacy of a possible drug that might eventually go on sale is definitely included, but screening studies to exclude candidate drugs that prove to be toxic probably is not. I have seen estimates that the actual number of animals used in all research is 10 to 50 times what the USDA reports, but these are from anti-vivesection groups, etc, so they have even less authority than the USDA numbers.
More significantly, the USDA numbers do not include animals that are involved in producing lab animals but are not directly used themselves. For instance when a strain of mice is developed for a specific trait, the young that do not exhibit that trait are destroyed, but that is not reflected in the USDA numbers. Cats, dogs, primates, and other subjects that are destroyed in developing techniques for implanting brain monitoring devices are not included.
The numbers of lab technicians and interns who are taught to disengage and suppress their normal emotional involvement with the animals they are handling significant. That "clinical detachment" is definitely an aberration from a healthy human psyche, and for that reason alone the use of animals in research needs to be as limited as possible. There are significant numbers of students who do not complete their training/education but who do learn how to turn off the normal human empathetic response when it gets in their way: that ability is part of the basis of terrorism and the kinds of mass shootings we have seen lately. We really don't need any more persons trained in that kind of "clinical detachment"; we need to curtail the number of persons we are exposing to this kind of training.
Are you and your colleagues actively involved in monitoring the use of laboratory animals? Can you provide more substantive data on how many are being used in the USA every year? If that is not the case, are you not a part of an ongoing problem?
