The new documentary GrowthBusters: Hooked on Growth explores why our economy and footprint and population can’t keep on expanding forever. It features green luminaries galore — Jane Goodall, Paul Ehrlich, Lester Brown, Raj Patel, Bill McKibben, Hunter Lovins. And, in the decidedly non-luminary category, I make a brief appearance too, talking about population and my decision to go childfree. Watch the trailer: 

If you’re in the D.C. area, you can catch the premiere screening on Nov. 2. If not, check out the screening schedule to find out if the film is coming to your town soon. Or buy it yourself on DVD.

Read more on population. Check out our series 7 billion: What to expect when you’re expanding.If you’d like to delve further into our growth dilemma, I recommend the new book The End of Growth by Richard Heinberg, known for his warnings about Peak Oil and Peak Coal. The book may freak you out — our current economic and social systems are poised for total collapse, he argues — but it’ll leave you wiser.

For a lighter and shorter perspective on our growth quandary, listen in on this conversation in David Roberts’ head.

This is the latest in a series of GINK videos about population and reproduction (or a lack thereof). It’s also part of Grist’s 7 Billion series.
