Sam Stea is a practicing physician, proud husband, and father of a wonderful son and daughter. Some time ago, Stea took a simple and deliberate step back from the complexities of life to see himself in a much bigger picture, within a context of past and future, within the balance of the human species with nature, and with what is truly lasting beyond one's own years. His great hope is that others in health care, physicians, nurses, therapists of all kinds, scientists and administrators, and young people everywhere will join him in his fight to better inform the public that climate change is the greatest imminent health challenge humanity has yet to face.
