Environment & Cost
Millions of animals are taken from their habitats annually for dissection. The World Conservation Union’s 2004 report found that a third of all amphibians worldwide are threatened with extinction. While the causes for this decline are varied, at least six million frogs alone are captured in the wild and killed for dissection each year in the U.S. As the most commonly dissected animal, frogs are especially sensitive to even subtle adverse changes in the environment; the large-scale removal of them from the wild exacerbates their already fragile populations.
As biological supply companies deplete frog and other amphibian populations, insect populations rise, and populations of species that rely on frogs for food decline. This can lead to increased use of pesticides by farmers who once relied on frogs to help control insects naturally.
Alternatives to dissection are extremely affordable. Modern computer programs and anatomical models can cost thousands of dollars less than animal specimens, last for years, and do not need to be re-ordered for each incoming class
