Thinking ecologically—about human health

Doctor and professor of public health Wendy Johnson saw in her medical practice people who thrived against all odds, and those who suffered grave challenges due to environmental factors like toxicity, poverty, stress, loneliness, and isolation. Her new book, Kinship Medicine, explores the reality that 80% of our health is determined by factors outside of us—which are largely ignored by our industrialized medical system. What's missing is ecological thinking, and understanding ourselves as part of an environment—from our microbiome to our community, to our ecosystem.
