1 in 4 women are induced in the United States. If this were actually necessary, there's no way the human race would have survived all of these thousands of years.
Interventions are tools, designed to accomplish a predisposed medical outcome. It is not the use, but rather the over use, of interventions that is problematic. Birth is inherently safe - interventions introduce new risks to the physiological birthing process. (adapted from the CAPPA Childbirth Educator Manual)
"Passion and love are as powerful a combination at birth as they are in sexual activity. And in birth, as in sex, we release oxytocin, the hormones of love, in huge quantities from deep inside the brain. Here again, our hormones are directing us toward optimal and ecstatic experiences, yet this system is extremely vulnerable to interference. … The drug Pitocin, which has been called the most abused drug in obstetrics... A synthetic form of the hormone oxytocin, it is used for induction and for augmentation (or acceleration) of labor. The majority of women in the United States receive large doses of this drug in labor." - Gentle Birth, Gentle Mothering by Dr. Sarah Buckley
