In Avengers: Infinity War the villain Thanos wants to solve overpopulation by exterminating half the population of the universe. Whenever overpopulation pops up in the movies, it’s always a villain with an inhumane solution. Dave and Dana discuss whether this helps or harms the cause of achieving a sustainable human population (yes, the world IS overpopulated today, and the forecasts are to add several billion more). Aren’t there humane, noble solutions to overpopulation?

Plus: Are we hardwired to reproduce? Population control, Paul Ehrlich, Thomas Malthus, Dan Brown’s Inferno novel and movie, Soylent Green, ZPG, and Dave’s Top 10 Overpopulation Films also come up. (See links below) . . .

While the U.S. announced intention to pull out of the Paris Climate Agreement is bad news, it seems to have inspired a lot of carbon-reducing promises at other levels across the country. And that is good news. In this episode of the GrowthBusters podcast, Dana and Dave lament the biggest hurdle in the path to a survivable climate – the fact that economic growth is the number one public policy goal around the world. In many cases it is the one thing policymakers won’t sacrifice in efforts to curb the growth of greenhouse gases in our atmosphere.

We seem to be putting all our eggs in the technology basket, hoping we can run an ever-growing economy on more and more solar, wind, geothermal and hydro power and use technology to shrink that mushrooming global economy’s carbon footprint. Some economists think we can do that. Many scientists do not. Ozzie Zehner, in his 2012 book Green Illusions, noted several studies that indicate we might need to change our ways beyond just switching power sources. . . .

Imagine you can live large – trophy house, fancy toys, caveman diet – but the costs are miniscule. Would you find that appealing? Or would you rather simplify your lifestyle and make your footprint the thing that’s miniscule? Is downsizing simply a way to supersize your consumption without maximizing your footprint? The latest episode of the GrowthBusters podcast examines these questions, as explored in the film, Downsizing.

“Downsizing may be about a small world, but it is an audacious, out-sized peach of a picture.”  – Ian Freer, Empire Magazine

The film, starring Matt Damon and Kristen Wiig, is now available for rent and purchase – on Amazon, GooglePlay and YouTube. The DVD is available on Netflix. GrowthBusters director Dave Gardner is joined by new co-host Dana Hicky to discuss the film, and that means overpopulation, overshoot, overconsumption, and climate change are on the agenda. . . .

Are human beings too stupid to manage the planet? Just asking the question invokes some misplaced conceit; we’ve wreaked havoc on the Earth largely because of our assumption that Earth is all about us. The truth is, we have no business trying to “manage” the planet. But, the scale of the human enterprise has become so gargantuan, that – in many respects – we ARE managing the planet (managing it into oblivion).

In the newest episode of the GrowthBusters podcast, we discuss a Raw Story interview with the great, great grandson of Charles Darwin. One of Chris Darwin’s thoughts is that we are poorly equipped to manage the planet. Of course he is right. Chris has launched an app called Darwin Challenge (link below). He’s also focusing a lot of attention on the destructive, unsustainable nature of our appetite for meat. . . .

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. . . .
