Man Should Be a Vegetarian
Man, naturally, should be a vegetarian because the whole body is made for vegetarian food. Even scientists concede to the fact that the whole structure of the human body shows that man should not be a nonvegetarian. Man comes from the monkeys and monkeys are vegetarians – absolute vegetarians. If Darwin is correct, then man should be a vegetarian. Now, there are ways to judge whether a certain species of animal is vegetarian or nonvegetarian: it depends on the length of the intestine. Nonvegetarian animals have a very small intestine. Tigers and lions have a very small intestine because meat is already a digested food. It does not need a long intestine to digest it. The work of digestion has been done by the animal and now you are eating the animal’s meat. It is already digested; a long intestine is not needed. Man has one of the longest intestines – that means man is a vegetarian. A long digestion is needed and there will be much excreta which has to be thrown out.
