A report in 2005 by the Environmental Working Group found two hundred eighty-seven chemicals in the cord blood of newborn babies, 208 of which are known to cause birth defects or abnormal development in animals, 217 of which are known neurotoxins, and 180 of which are known carcinogens. This may be the cause of the significant increase in chronic illnesses in children and a reason that more adults are facing the same.
