You nailed it, natural is good but it is not always the best. We can't compare natural with artificial when it comes to medicine. I was discussing with my mother recently how that death as a result of childbirth in women has drastically reduced recently.
Technology has greatly helped in terms of health services and I am glad it is ever increasing. Natural is good but unfortunately, we can't depend on it alone.
Nature is good but we need to balance it with artificial too.
