I'm actually a vegetarian, not because of peta or nasty slaughterhouse videos, i personally believe that as mammals, humans aren't above any others in a spiritual sense, eating a cow is like eating a person
also, regarding the elephants in the video, you have to be an idiot to try to domesticate an elephant. Look up some stories, in India elephants may go and kill half of a village because they're mad. seriously look how many people it takes to kill ONE pissed-off elephant...bad idea.
