Overdrafting Earth's Ecosystems | William Rees

“The only way out of overshoot is less production and less consumption, so it means a much smaller economy and far fewer people.” William Rees, ecologist and co-creator of ecological footprint analysis, joins us. “Humankind is using up the biophysical basis of its own existence.” That’s the bottom line of this Earth Overshoot Day conversation with William Rees, the father of ecological footprint analysis. According to Rees, “the only way out of overshoot is less production and less consumption, so it means a much smaller economy and far fewer people.” Earth Overshoot Day in 2021 is July 29. At this point in the year, we've already demanded a year's worth of the Earth's sustainable regenerative capacity.

The podcast explores needed narrative, behavioral, and system shifts for recreating human life in balance with all life on Earth. With expert guests from wide-ranging disciplines, we examine the forces underlying overshoot: from patriarchal pronatalism that is fueling overpopulation, to growth-biased economic systems that lead to consumerism and social injustice, to the dominant worldview of human supremacy that subjugates animals and nature. Our vision of shrinking toward abundance inspires us to seek pathways of transformation that go beyond technological fixes toward a new humanity that honors our interconnectedness with all beings.  Hosted by Nandita Bajaj and Alan Ware.
