Hurricanes, Climate Change & Contraception (Podcast Episode #19)

Yes, they are related. Our business-as-usual response to Hurricane Florence last month starts the conversation. (This episode was recorded before Hurricane Michael devastated the Florida panhandle.) Grace and Dave do also share some good news: climate change is getting more attention (of course the recent IPCC report has turned that volume up to 11, and we’ll discuss that in the next episode).

Also in this episode: Does Dave need to shut up already about using condoms? How reliable are various forms of contraception? A challenge to the top environmental NGOs to start telling the truth about the unsustainability of economic growth. And a politician startles the world by quitting because his government isn’t doing enough about the climate. . . .

Overshoot - 1.7 Earths

How Fast is Our Goose Being Cooked? (podcast episode 18)

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. . . .

Donald Trump and growth chart turning down

Trump Can’t Keep It Up (Economic Growth) – Podcast Episode #17

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. . . .

What is Earth Overshoot Day?

Earth Overshoot Day (Podcast Episode 16)

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. . . .

Do Only Villains Care About Overpopulation? (Podcast Episode 15)

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 GreenZPG, and Dave’s Top 10 Overpopulation Films also come up. (See links below) . . .
