I have always believed that having animals in the science curriculum is a great way to learn about the systems of the body. I also believe the use of animals sparks the love of science and gives inspiration to future careers and likewise informs people whether or not they have the gut to deal with the dirty work. The experience is very important and very useful. Also having live animals in the class help students understand how animals interact in different environments. This also helps the students understand why animal research is so important. for those who put up the case that dissection is inhumane there are rules that protect the animals from improper treatment and most of the animals used have a really high population so that it does not damage the ecosystem.
