Before continuing with the discussion about vegetarianism or other dietary choices, a couple of questions should first be asked. One is: Why do we eat? If that sounds a little silly and rhetorical, then try another question: Why do humans have the longest childhood of all known animals, requiring around 20 years before full maturity? No other creature needs such a long time to mature – even whales are considered mature between seven to 10 years of age.
The answers to both questions are related, and complex – and they start with human breast milk.
