Humankind has outgrown the planet, so we explore ways to recover from growth addiction. We dig into the more fascinating and hard-hitting aspects of public policy and the joy of living sustainably. It’s all about ending our culture’s love affair with “more,” which is not making us happier and is killing our planet. No half-hearted greenwashing here; we share the brutal and joyful truth! Co-host Dave Gardner directed the documentary GrowthBusters: Hooked on Growth, which Stanford Biologist Pa ...

A new study debunks depopulation panic. For decades economists have perpetuated the false narrative, “If population growth reverses and begins to decline, the economy is doomed.” This belief has so frequently been repeated by economists, politicians, business people and the public, that it is generally taken as gospel. Psychologists have characteri…

The Michigan Governor is apparently unaware that the world, the U.S. and even Michigan are overpopulated. Michigan population has been growing a little too slowly for her taste, so Whitmer has appointed a Chief Growth Officer and formed the Growing Michigan Together Council. Not surprisingly, her bottom line is to “spur economic growth.” In an epis…

Are many vegans self-righteous, overbearing and insufferable in their efforts to recruit us? Would you believe “overpopulation” is still a taboo word? Or that human population numbers are still an “off-limits” topic at some conferences? This episode continues the conversation we began in episode 79 with five smart people: Nandita Bajaj, executive d…

Five thought leaders break the silence on the role of human overpopulation in ecological overshoot –with an informed, engaging conversation about the subject. This is what intelligent discourse sounds like. For thirty years, many people – some well-intentioned – have been trying to silence discourse about human overpopulation. One of our goals on t…

Why do discussions of overpopulation often elicit emotional responses of fear, anger, or indignation? Are anger and indignation what prevents productive discussion of population? These responses in a graduate college class provide an opportunity to explore how we might pave the way for productive conversations. Our guest in this episode, Professor …

The news that China’s massive population dropped by nearly a million people last year was almost universally reported as a “crisis.” In this episode we unpack the news coverage and take journalists to task for completely overlooking the fact that, in an overpopulated world, population contraction should be greeted with a collective sigh of relief. …

More men are stepping up and taking responsibility for avoiding unplanned parenthood. Dave celebrates this trend as he shares GrowthBusters plans for the new year in this special year-end mini-episode. A typical vasectomy takes about ten minutes. It’s much less invasive, and less expensive, than the equivalent procedure for women. GrowthBusting hig…

Examining news coverage and commentaries about human population passing 8 billion on November 15, we unpack the reasons far too many of us avoid discourse about human overpopulation. Why are we tap-dancing around the very dialogue needed so people around the world can make informed, responsible family-size decisions? We conclude the guilt many feel…

While Elon Musk erroneously claims population collapse is our biggest worry, world population is hitting 8 billion, adding the latest billion faster than any time in history. The UN has declared world population will surpass 8 billion on November 15, 2022. We persist in adding about 80 million people to the planet every year, despite overwhelming e…

World population may peak this decade and start dropping, over 60% of Coloradans are fed up with the negative consequences of growth of their communities, a new online community and resource for sustainability advocates, Elon Musk keeps populating our conversations, and should Dave run for president of the U.S.? Stephanie and Dave sit down with pro…

As we approach the 8 billion population milestone, activist/author Valorie Allen thinks it’s high time we stop avoiding the overpopulation subject. Yet here we are, on World Population Day 2022, and the UN is still beating around the bush, journalists rarely report on the subject (and when they do, it's usually with a pro-growth bias), and most env…

Biologist Paul Ehrlich reflects on the 1972 MIT study, The Limits to Growth, on its 50th anniversary – including the fact that it has been refuted (poorly), ignored, and confirmed. The study was done by a team of scientists commissioned by the Club of Rome to develop a computer model to simulate the interaction of earth and human systems. It reveal…

While nary a week goes by that we don’t get a new report of the destruction we’re wreaking on our home planet, the news has been particularly bad over the last few weeks. Plus: Bill Maher, usually praised by us for speaking the truth, needs to get there on the benefits of a shrinking economy. We devote half of this episode to the news, and half to …

Should we be sitting around eating burgers and driving pickup trucks, and just wait for the system change needed to live sustainably on this planet? We attempt here to put to rest the tired and misdirected debate about whether individual footprint-shrinking action is a distraction that slows needed systemic change, and whether it's worth doing. Joi…

OK, boomers, we blew it. Our best hope is that younger generations are aware and smart enough to save the planet. What do they know, and what are their planet-saving intentions? We went straight to the source, and sat down with a University of Denver Ecological Economics class to get their perspective. This conversation explores awareness and solut…

Get married, buy a house, raise a family. For many of us, that’s the expected life trajectory. Are we entitled to meet that expectation? If many follow the typical trajectory, including having two or more children, then we drive human civilization right off a cliff. On an overpopulated planet, does society have an obligation to make parenthood poss…

“If people don’t have more children, civilization is going to crumble,” according to Time Magazine’s “Person of the Year” – Elon Musk. He is, of course, dead wrong. We briefly explore that in this episode, and offer our take on Musk’s stone-age solutions to traffic congestion. We also share thoughts about several growthbusting news items: Recent Ar…

The climate pact achieved at COP26 was woefully inadequate. We could be in for over four degrees Fahrenheit of warming this century over pre-industrial temperatures, and some scenarios would put us closer to eight degrees. In this episode, Paul Sutton shares his observations from Glasgow, and we get assessments from a few other noted experts. Polic…

We generate 23% more waste during December than other months of the year, but more than three in four Americans wish the holidays were less materialistic. Our retail and consumer culture have gotten out of hand over holiday gift-giving. 9 in 10 believe holidays should be more about family and caring for others than about giving and receiving gifts.…

We’re running out of booty on planet Earth, so billionaires are racing to mine and populate the rest of the universe. In this follow-up to our Billionaires in Space episode, we examine and applaud points made by economist Tim Jackson in his recent essay, Billionaire Space Race: The Ultimate Symbol of Capitalism’s Flawed Obsession with Growth. We al…

“Once a species becomes powerful enough to take over a planet, then is it also intelligent enough to understand the limits to its own power?” This is a question posed in the new book, Power: Limits and Prospects for Human Survival. Author Richard Heinberg is a Senior Fellow at Post Carbon Institute and author of 13 books, including Power Down, The …

In this episode Mike explains why he is promoting the mantr…

Can we achieve some unity without giving up our integrity and core values? That’s a very current conundrum, so this seems the perfect time for us to publish this conversation.

If we were on a spaceship, the end really would be near – August 22. That is Earth Overshoot Day for 2020. We all know we can’t graze 100 head of cattle for long on a one-acre patch of land. We’d have a barren wasteland and a bunch of dead cattle in no time. It’s a little more challenging for us to make this calculation about meeting the needs of 7…

Is there any use in choosing to live more sustainably if you’re surrounded by an unsustainable system?

Coronavirus has brought the economies of the world to a grinding halt. The world is (almost) universally mourning the recession – almost.

When the world’s scientists are concerned enough about something that they issue a warning – to the world, you might think we’d all take notice. Once you get to three warnings, however, well, you start to wonder just how intelligent we humans really are. After a 1992 warning, and another in 2017, world scientists have this month issued what our gue…
