Podcasts come in all shapes and sizes. Short, pointed and single-header stuff (take a bow Alex Steffen). Looooong, not quite as insightful as it thinks it is, single-or-multi-header (you know who you are – as in, if you think this is about your podcast, it probably is).

a) about a really important topic
b) not a second shorter or longer than it needs to be
c) super use of archival audio.
The Tipping Point series, a three-parter on the origins, reception and after life of the Club of Rome’s The Limits to Growth report is all of those and more. LISTEN TO IT NOW FOR THE LOVE OF GAIA.

It is what popular education should be, but so often isn’t.
Would I have put a bit more in there at the beginning about previous efforts to raise environmental alarm? Yes, but thank goodness I was not running the podcast, because it would have dragged the whole thing down. There could be a different podcast about that, the “before the Limits to Growth” – from, say, Malthus, through Vogt and Osborn to Carson and on to Ehrlich. That I would listen to. For now, though…
