Farm animals and humans
Link: BBC NEWS | Science/Nature | Farm animals.
I was reading this article on BBC describing that even farm animals like cows and sheep can feel different emotions and are intelligent. Scrolling down I saw this comment, from someone in UK:
" Animals are stupid! I saw this group of animals only the other day attacking a lone animal of their own species for no other reason than he was a slightly different colour! In another instance I observed a large group of these animals stockpiling food only for it to rot rather than sharing with other animals nearby who were starving. We should think ourselves lucky we’re not so dumb and we can invent things like nuclear weapons to protect ourselves. "
Nice sarcasm
