In a hypothetical situation I am a vegan talking to a meat eater who buys his meat from a supermarket and has no interest in where it came from. I say that I don't think people have the right to eat meat unless they are willing to learn about what it takes to provide that meat, witness it first hand or even produce it for themselves. He says that he doesn't want to know where it came from and is quite happy for someone else to do the dirty work if they are happy to and does not feel at all guilty. Is he morally wrong and do I have a valid argument?

Omnivores are often defined as opportunistic feeders, in other words; they eat what they can get their hands on. As vegetarian sources of food are generally plentiful in the developed world; are there any valid reasons for eating meat? I’m finding it extremely difficult to think of any rational reasons for eating meat in my own life since I’m entirely able to survive on vegetarian options whilst still getting the nutrients I require. The strongest ‘weak’ argument I’ve came up with is it is ‘natural’ for us to eat meat – our bodies are able, and ready, to digest it. Like I said; this argument doesn’t win me over; there are many ‘natural’ things in this world that aren’t necessary for one to live a good life (and many more to contradict living one). For example; cancer is entirely natural – it is observed in the natural world. Likewise; the process of rape as a means of propagating has been observed in the animal kingdom (i.e. in chimpanzees and even dolphins), but I would never use the ‘natural’ argument...
