Cows are naturally herbivores, but many are fed a meat and bone meal made from the remains of other cattle. We know that feeding beef products to cows is the cause of Bovine Spongiform Encephalopathy, more commonly known as Mad Cow disease. If we ban this practice by requiring that all cattle is fed a 100% vegetarian diet, we should be able to greatly reduce and maybe even eliminate instances of mad cow disease.

Mad Cow disease can be transmitted to humans who eat beef products from infected livestock, causing a variety of neurological symptoms and dementia.
