As I read this article over at ABC news all I could think of was, "But will any large number of people be willing to trade higher infant mortality for a lower incidence of asthma?" Cleaner living may not challenge our immune systems like living in an open sewer but this may just be a price we have to pay. I can imagine that if Dr. Parker can isolate one or a number of non-pathogenic challenges that this might be good thing but this will, I imagine, take a while.
