Next, Host Steve Curwood and the Living on Earth team explore Earth as a complex and self-sustaining organism called Gaia. Over billions of years life has interacted with the air, water and rocks of this planet to keep life in the sweet spots for temperature and resource supplies. With the help of scientists, deep ecologists, children, an astronaut and more, we explore our place on this living planet.

Science and policy are vital in building a more sustainable world, but they often don’t convey the values we need in order to engage people to do so. With spiritual guides who carry diverse traditions and teachings, Host Steve Curwood surveys the values that can guide us along this path towards ecological harmony. Indigenous stories, holy scriptures, East Asian cosmologies, papal encyclicals and divine revelation all shed light on our duties and relationship to each other and to our common home.

As we celebrate Living on Earth's 30th year on the air, we're offering an Earth Day special that examines this decisive moment for the human species and our challenging relationship with our planet. Host Steve Curwood starts by meeting people who envision a future reshaped by an emerging energy system and new power structures, as we wean off of fossil fuels.
