Can Americans get over our love affair with big, gas-guzzling pickups and SUVs? Are you considering environmental impact when you choose your car or coffee maker? One of our goals at GrowthBusters is to make it second nature to consider your footprint in all you do. The newest episode of the GrowthBusters podcast examines EPA plans to rollback auto fuel efficiency standards. What policy prescriptions would be fair AND effective in encouraging us to make lower carbon-footprint decisions?

The Ultimate Guide to Recycling K-Cups, from Consumer Reports, sparks a lively discussion and quest to determine the lowest-impact way to brew your coffee. Did Ben and I hurt Kaitlyn and her parents’ feelings when we characterized the Keurig single-serve coffee craze as “silly”? Not our intention, but what do you think? Do we really need single-serving coffee pods? You might be surprised that these account for a huge percentage of the coffee maker market. The conversation does reveal fascinating facts about the recyclability of various types of pods. . . .

Are children bad for the health of the planet, and therefore human civilization? Should we stop making them? Or do we need to step it up and make lots more than we’re currently making (does anyone have a good recipe)? Or does the intelligent answer lie somewhere in-between?

The GrowthBusters podcast team doesn’t shy away from tough topics when the fate of human civilization hangs in the balance. In this episode, Ben, Kaitlyn and I discuss recent news headlines about fertility rates and offer their opinions on the views of Matt Lewis (The Daily Beast) and Travis Rieder (Berman Institute of Bioethics). Over 15,000 of the world’s scientists also weigh in. . . .

The new GrowthBusters podcast is now active, with three episodes available now for your enjoyment and enlightenment.

Why a GrowthBusters podcast?

Many lively discussions begin on our webinars, on my media bias analysis at www.growthbiasbusted.org, and in response to Facebook posts. And those have continued here in the office (thanks to the presence of our two student interns, Kaitlyn and Ben). So, we decided the time is right to launch an official GrowthBusters podcast.

You can listen to the first episodes right here (just below, in this post), or you can find the GrowthBusters podcast (and subscribe, for free) at iTunes, Stitcher or the Apple Podcasts app. Subscribing means you’ll automatically get new episodes when available. (You’ll also find a couple of old episodes of our Paving Paradise podcast, which I started last summer but abandoned due to lack of time.) . . .

Here’s the 7th and final installment of questions from our Solving Overshoot webinar. I’m sharing the questions we didn’t have time to address, and I’m including comments received from Madeleine Somerville and Paul Ehrlich, our panelists. If you missed the first few installments, start here with installment one. Your comments are welcome below. I’ve jumped in and offered some of my own thoughts because of the importance and relevance of these. I look forward to reading your thoughts.

24. Libby Sharpe asked: “I hate to be the one to raise the immigration question, but any thoughts about that? I am compassionate toward immigrants, but it seems to me that unfettered immigration just disseminates populations without lowering birthrates, as much of the immigrations is from countries where there is high selective pressure for increased birth rates.” . . .

Here’s the 4th installment of questions from our Solving Overshoot webinar. I’m sharing the questions we did not have time to address, and including any comments I received from Madeleine Somerville and Paul Ehrlich, our panelists. If you missed the first few installments, start here with installment one. Your comments are welcome.

12. Brian Sanderson asked: “Which is easier to alter, per-capita consumption or overpopulation?
Ultimately, if nothing is done, nature will force a reduction in per-capita consumption.
On the other hand, if the question is which we as human agents will find most easy to alter, it’s population that is easier. The data are clear on this.”  But it would take something like a century to get significant shrinkage, and we likely don’t have a century. . . .
