Bill

Bill Frist, the former Republican Senate majority leader, racked up a slew of notable medical successes during his years as one of the country’s top heart and lung surgeons.He founded one of the country’s busiest transplant centers. But now, Mr. Frist, 74, advocates for the health of the biggest, most famous patient of all: the Earth. In earnest writings, folksy videos recorded on his front porch in Tennessee, podcasts, speeches and congressional testimony, Mr. Frist has been highlighting the inseparability of planetary and human health. “A healthier planet means healthier people,” Mr. Frist said. “The science shows it. Our experience shows it. Nobody can really argue against that.”
