Mad Cows

In environmental chemistry, I am doing a prezi about mad cow disease. It turns out it is some scary stuff. It affects the cows nervous system and makes them act strange and loose their ability to walk.  It can spread to humans if they eat the brain and/or spinal tissue, or the meat surrounding it. TIME FOR SUPPER!!!!! TASTY!!!!   that is also how it passes from cow to cow.  I know you are probably thinking WHAT!?!? COWS EAT OTHER COWS BRAINS AND SPINAL TISSUE!?!?  but there are other ways a cow can unknowingly eat fellow cows brains.  People mix useful cow parts into their feed.  The poor moo cows have to eat their fellow cows brain.....I'm very happy I'm not a cow. The disease effects the human nervous system as well.  It can cause dementia and it is fatal.  So if I were you I would keep cow brains and spinal tissue out of your diet for good.
