Each year millions of animals are dissected in high school classrooms. These animals are taken from the wild, disturbing the natural cycle or purchased from breeding facilities who cater to the experimentation of animals. It is unnecessary and inhumane and many students are taking a stand against dissection in their schools as there are many humane alternatives, such as computer simulations and life size models. "Research has shown that a significant number of students at every educational level are uncomfortable with the use of animals in dissection and experimentation." High school students do not need to know how to properly dissect any animal at there level of education and the money put towards purchasing these animals in high schools could be used for a number of other schools supplies needed such as text books.
