indeed, I feel really bad after I watched the movie, The COVE, about Japanese hunting on dolphins. not only because I have special feeling on dolphins (more than other so-called intelligent animals like dogs, pigs, seals...), but more because of the mercury
Now I alredy stop eatting tuna coz it is said it contains a big amount of mercury.
And about the brain wash discussion, I think in the end killings are all cruel on any creatures with consciousness. It is more of a emotion and direct feeling problem than a logical issue. In a one part of a logic world, in the name of selfish gene, killings
proves the ability of survive. It helps innovation, evoluation, modernization and world equilibrium.
Eatting beef is pretty ok, but you may feel bad when u see calf is killed. it is just like, Pressing the bottom of a gas chamber was much easier than murdering someone by knife....Mencius said it is a 恻隐之心，it is, in most cases, more of a illogical instinct
rather than a culture, cultivated thing.
