People and their unquenchable thirst for exotic animals... Why would anybody in his right mind keep dangerous animals?! We have rheas back home (we call them Ñandus) and, although they are not anywhere as dangerous as the cassowaries, we know to stay away from them. Their legs are incredibly long and strong and they use them to attack as well as their large beaks. These birds are taller than people!
