Easily . I have a degree in biology , I can tell you now that all these behaviors are completely natural , however uncomfortable it may be to believe . If you wish it of me , I ' m willing to back up my claims with the appropriate sources . A Naturalistic fallacy is the mistaken belief that because something is natural , it must be good . There are many examples of behaviors which are completely natural , but no reasonable person would consider morally acceptable . Meat eating has been ingrained in our culture and has been necessary for our survival in the past , so I understand that it is difficult to group alongside other behaviors such homicide , rape etc . However , how different is it really ? To eat meat , you make the choice to take a sentient being ' s life against its choice . To produce dairy , the cows are effectively raped to become pregnant and produce milk . These things are acceptable because it ' s a cultural paradigm to accept that this pain and suffering are a necessity to produce our food . Yet today , most of us live in a world in which we do not need meat to survive .
