What happens to the animals used for dissection?
Some animals, such as amphibians and reptiles, may suffocate or become crushed during transportation to biological supply companies; most of the animals used for dissection are killed and processed at such companies. Undercover investigations have revealed animal abuse at biological supply companies. Frogs, for instance, may be piled into bags for days or even weeks while still alive. Rats may be embalmed alive. Cats may be forcibly injected with preserving fluids after being only partially euthanized, thrown into gas chambers, or drowned. The Effect on the Environment When one type of animal is removed from an ecosystem, the entire food chain is affected. Frogs, for example, naturally consume many insects. With so many frogs disappearing (as a result of habitat destruction, pollution, and dissection), the insect populations have risen substantially. Because there are more insects, there is greater use of pesticides, which can damage the water supply and food chain. Types of Classes in
