Paul Ehrlich: “Was the Population Bomb Defused?”

TGS09 Paul Ehrlich The Great Simplification

On this episode, we meet with Professor Emeritus of Population Studies at Stanford University and author of The Population Bomb, Paul Ehrlich.

Ehrlich discusses what has happened with the human population situation in the decades since he published The Population Bomb. Why has humanity not responded to our long-term sustainability challenges? How would Ehrlich frame contemporary discussions about population?

In a wide-ranging conversation spanning stories about his appearances on The Tonight Show Starring Johnny Carson to how the environmental movement merged with corporate greenwashing, Ehrlich provides colorful and interesting commentary on the human predicament.

About Paul Ehrlich

Paul Ehrlich is the Bing Professor Emeritus of Population Studies at Stanford University and author of many books, including The Population Bomb.

In French, we have a motto that says that a simple drawing is often better than a long explanation. Jean-Marc Jancovici Carbone 4 President

That’s very understandable because with left atmosphere thinking, one of the problems is that you see everything as a series of problems that must have solutions. Iain McGilchrist Neuroscientist and Philosopher

We can’t have hundreds and hundreds of real relationships that are healthy because that requires time and effort and full attention and awareness of being in real relationship and conversation with the other human. Nate Hagens Director of ISEOF

This is the crux of the whole problem. Individual parts of nature are more valuable than the biocomplexity of nature. Thomas Crowther Founder Restor

Algorithmic CancerWith Connor LeahyThe Great SimplificationEp 184 | Connor Leahy

Recently, the risks about Artificial Intelligence and the need for ‘alignment’ have been flooding our cultural discourse – with Artificial Super Intelligence acting as both the most promising goal and most pressing threat. But amid the moral debate, there’s been surprisingly little attention paid to a basic question: do we even have the technical capability to guide where any of this is headed? And if not, should we slow the pace of innovation until we better understand how these complex systems actually work?

Rod SchoonoverThe National Security Risks We’re Not Prepared ForWith Rod SchoonoverThe Great SimplificationEp 183 | Rod Schoonover

National security concerns have been the invisible hand guiding governance throughout recorded history. In the 20th century, it was defined by a country versus country dynamic: whichever nation was the strongest and most strategic was also the safest. But today, our biggest national security threats don’t come from opposing nations – they are “actorless threats” that emerge from the breakdown of the complex systems we all depend on – from the stability of our planetary systems to our intricately complex and fragile global supply chains. In this unprecedented landscape, what is required of us in order to keep our citizens safe?
