Explanation:

Eating meat is an extremely complex and difficult topic, because it involves a great ethical dilemma. This ethical dilemma is related to the realization that it is not correct to cause pain and fear in animals, but human beings supply many of their needs with animal products, especially meat. In this sense, many people claim that animals should not suffer in order for the human race to be served, since there are other non-animal sources that can be used. However, other people affirm that these products are important for the health of the body and that these animals are already bred for this purpose.
