When I was reviewing Paul Gilding’s book The Great Disruption I was frequently aware of similarities with Lester Brown’s writing, most recently World on the Edge. The parallels were highlighted further for me when I viewed an excellent recent documentary on Lester Brown’s advocacy which has recently screened on PBS in the US. I recommend the film as providing a clear overview of Brown’s thinking. It is available streamed during the month of April. For those who don’t have the time to look at it I’ll briefly highlight one or two significant points which are echoed by Gilding and which sound themes that are surely central to any hope of preventing the full danger inherent in climate change.
