Did the heroes solve a problem or make it worse? Did super-villain Thanos in the blockbuster movie, Avengers: Infinity War, solve the overshoot problem when he killed off half the beings in the universe to end overpopulation? Should the Avengers undo his deed if they can? Dave and Erika dissect Avengers: Endgame and how it treats these sustainability issues.

We’re looking for a podcast editor or producer with great audio editing skills. If you’re interested, email us.

Do Only Villains Care About Overpopulation?
We dissected last year’s Avengers: Infinity War in GrowthBusters episode 15. . . .

How do we handle the despair of knowing we may not win this battle with climate change (which is really a battle with ourselves)? Should we keep fighting? And if we do, WHO needs to be making the drastic changes we know are needed to avoid the worst of climate change disaster? Is it you and me? The big corporations? Or is it our elected policymakers? Are we assuming too much personal responsibility for goosing climate change or not enough? Are we in such a dire situation that we shouldn’t even bother “greening” up our lives, because that is so far from enough?

In this episode former UK Guardian columnist and author of All You Need is Less, Madeleine Sommerville, joins host Dave Gardner to ponder these questions. . . .

Is Earth Overshoot Day meaningful? How sound is ecological footprint and biocapacity data behind it? Dave and Grace examine a critique from Robert B. Richardson, Associate Professor of Sustainable Development at Michigan State University.

Plus: This summer’s heat and fires are NOT “the new normal.” (It will get worse. Sorry.) More forest fire destruction comes with climate change. If you want to be a green hero, recycling is not nearly enough. How women who decide not to have children are treated. Men should take more responsibility for contraception.

Note: The forest fire story mentioned in this podcast as from the Washington Post was actually an AP story. . . .

We should NOT be celebrating (or pursuing) 4.1% economic growth, according to co-host Dave Gardner. Listen to this podcast to find out why pursuing GDP growth today is suicidal. Also on tap, listener comments about Earth Overshoot Day (the subject of our last podcast), and more single-use plastics we want to avoid. Dave stumps us with this question: What single-use disposable item do we want to see used more widely? Try to guess before Dave gives you the answer halfway into this episode.

In this episode we hear U.S. President Donald Trump brag about economic growth at a 4.1% annualized rate. Even his sharpest critics celebrate robust growth, as we hear from Joe Scarborough and Mika Brzezinski on Morning Joe. Many economists responded to this news that they don’t think we can keep that growth rate up, but their reasons differ from Dave’s. On a finite planet, perpetual growth in economic throughput is impossible. . . .

Did you know we are in overshoot? What does that mean, and what should we do about it? Also in this episode, which has a smaller footprint – milk, or milk alternatives like almond milk? Dana informs us that, “Eating food is one of the worst things you can do for the environment.” Are some health departments preventing bulk filling of reusable containers? Carrying reusable utensils and napkin on your travels. And choosing carefully the trash can in which to deposit your refuse.

August 1, 2018 is Earth Overshoot Day. Data collected and analyzed by the Global Footprint Network tells us this is the date when humanity’s annual demand on nature begins to exceed what Earth’s ecosystems can regenerate in the entire year. If it falls anytime before December 31, it means we’re using more ecological resources and services than nature can regenerate – through activity like overfishing, overharvesting forests, and emitting more carbon dioxide into the atmosphere than ecosystems can absorb. . . .
