Animal rights organizations estimate that approximately 500 million animals are killed annually as a result of their use in science. Although this figure accounts for 5 percent of all animal deaths by human intervention, clearly the impact of scientific research on animal mortality is significant. Estimates of the number of animals used annually for biological research alone range from 15 million to 120 million (2:197-199). Animals serve a wide variety of purposes in scientific research. Animals are used to test the safety of consumer products, e.g., the toxicity of pesticides or household cleaners. Test animals are injected with the product, force-fed it, have it rubbed on their skins, or have it dropped in their eyes. Animals used in behavioral research are usually subjected to psychological deprivation or distress as opposed to physical pain.
