Nowadays, there are many types of medicines made from animals and used as traditional medicine. For example, in East Timor, which is the second newest country in the world, the local community uses deer blood to treat cancer and tumors. Surprisingly, it worked perfectly and obviously it will be really helpful for the local community in that area, as we know that cancer and tumor are two types of malignant tumors in the world. Furthermore, according to the World Health Organization (2007) in the Britannia Encyclopedia, almost four-fifths of human needs related to medicine for human primary health are met by plants and animals, especially in China, where they are most used by traditional medicine. Having the detailed explanation mentioned before, we clearly understand that everyone in the world must protect the endangered animals because as human beings we will always use some animal species as important raw material to produce medicine in the world.
