Don't forget about for example Nestle giving doctors money to tell new parents to use Nestle products instead of mothers milk. Mothers milk is the best for children and is very important for their immune system. I'm all for saving lives, but there are some very greedy people in the world, and to some account Hanlon's razor. Antibiotics has side effects, such as killing all bacteria. Our life depends on many of the bacterias living in our body, especially in the digestive system.
