A controvensial topic about the right of animal In recent years, there has been much controversy over the cultivating of animals for feeding. In the past, The ancients lived in a harsh environment, fighting against the beast and hunting for living. As the cultivating technology developed, our ancestors tended to plow, or feed some animals such as pigs and chicken as food resources. The animal right folks view the cultivation of animals for food as a brutal behaviour. A large proportion of these people are vegetarian, and they always claim that the animals, even meat pigs have the same right as humans to live in a free environment, and cannot be killed for pork at will. The domestic animal is also a life, and it has emtions, and should be treated equally. Conversly, those who consume a lot of meat everday may think that the dishes made from meat are really tasty. They have spent a lot of time and materials on cultivating these meat animals, thereby treating them as a source of food is reasonable. Another viewpoint is that humans have been at the top of the food chain, so they can eat what they want to. If the pig live in the jungle, they will be killed by other big cats such as tigers as well. In my view, I think the cultivation of tamed animals as edible materials is reasonable, and is just a consequence of competition in the nature world. However, hunting or killing the endangered creature should be banned, since they are also invaluable.
