Interviews and ideas on the changing state of our world. How can we meet the needs of the estimated 9 billion humans who will inhabit the earth in 2050 when the natural environment seems already to be stretched beyond its sustainable limits? How can the economy be restructured in a way that will provide for everyone fairly while respecting the earth's ecological and resource limitations? What is the way forward and how do we get there? These are some of the questions being explored through the Earthgauge series of podcasts.
