After billions of years of Earth’s development, it’s still the same five elements that shape so much of human evolution. Stephen Porder is associate provost for sustainability and professor of ecology, evolution and organismal biology at Brown University. He is also a fellow in the Institute at Brown for Environment and Society, and he joins host Krys Boyd to discuss hydrogen, oxygen, carbon, nitrogen and phosphorus and how these building blocks of life affect the climate. His book is “Elemental: How Five Elements Changed Earth’s Past and Will Shape Our Future.”
