Illegalize the dissection of animals in schools

Schools all over the nation are disecting cats, frogs, chickens, mice, ect. There is no real need to dissect these animals. What good is dissecting a frog if you are going to become an accountant? They are killing animals so we can take a look inside and then just toss them aside. The companys supplying the animals are "creating" the animals for the purpose of later killing them. Please help me to prevent this act from continuing on!
