The essence of the proposition that Professor William Rees presents in The Human Ecology of Overshoot: Why a Major ‘Population Correction’ Is Inevitable, is that human population, consumption and pollution have combined to exceed the ability of our planet’s limited ecological systems to sustain it.

Reality 101: Overshoot
The podcast and article that follow expresses opinions not necessarily shared by the Cortes Radio Society, its board, staff, volunteers or membership.

Editor’s note: Reality 101 with Rex Weyler was one of the lunchtime lectures at Cortes Island’s Folk University. This session was recorded and broadcast over Cortes Radio in the regular Cortes Currents slot on November 6, 2019. The theme is overshoot, and what this means to the future of humanity and our planet. Rex also writes about overshoot in the article below; the embedded podcast is Rex’s Folk U presentation.

- A: Build higher dikes to fight it?
- B: Develop underwater transit technology to embrace it?
