Authors note: I am just placing scientific discovery here in a black and white sense. Animals are animals. Animals have emotions, I know. What do we do in return for our meat consumption? Positive actions would be a good start in exchange for their nutrients, in my view.
Milton (1999) findings suggested that humans have a long history of eating meat.
An ape’s gut has a colon, a large winding tube designed to process a vegetarian diet.
Human gut is dominated by the small intestines. Proteins are rapidly broken down and nutrients absorbed.
The human body doesn’t produce Vitamin A and Vitamin B12. Both of which are vital for human survival. These two are found in meat.
