Why should we do that? Animals can provide us with many useful things. Wherever we live, we gain profits from animals. Imagine what our life would be like if we were dispossessed of meat, egg and milk, let alone many services animals provide free of charge. In other words animals play an important role in the progress of our human beings. It seems that we cannot live without them, because we make clothes out of their skins and take their meat as food. Human beings are omnivorous animals, but vegetables and fruits do not contain all the nutrition we should take our live a healthy life. In fact, many animals we use are raised artificially. Therefore, meat is essential in our daily life.
As we all know, since human beings existed in the world, animals have always been accompanying with us. Since the primitive society people begin to eat animals meat. Why people should eat animals we need get energy and nutrition from animals. The energy includes heat and carbohydrates. Also the nutrition at least includes seven classes of nutrients people’s body need. Some people will say we can get nutrition from vegetables and fruits, that’s not enough. According to Hilling in 2011.Human beings are omnivorous animals, but vegetables and fruits do not contain all the nutrition we should take to our live a healthy life. The animals what we eat just rise artificially. Means people can make more animals from one animal.
