Welcome to Overshoot: Have a Nice Day - 2020 Edition
The best scientific estimates tell us human civilization is in overshoot. Were you aware of this? Do you know what overshoot is? Earth Overshoot Day in 2020 is August 22. Computer modeling by a team of MIT scientists in 1972 estimated the scale of human activity on the planet would cause systems to fail within a hundred years. Such failure is expected when humanity’s footprint on the planet consistently exceeds its carrying capacity. Since 1972, study after study, and report after report, has warned we are in overshoot – the sum total of human activity is too much for the Earth’s ecosystems to bear. Since 2003, scientists at Global Footprint Network have been analyzing UN data and satellite imagery to estimate the planet’s capacity to meet our needs (biocapacity), and humankind’s footprint - or demand (ecological footprint) - on that capacity. Their analysis suggests we have been in overshoot since about 1970. Welcome to Overshoot explores overshoot’s causes, effects, and possible solutions, as well as some of the barriers to solving the problem.

Durable Future: Bill McKibben (#115 Encore)

Durable Future: Bill McKibben (#115 Encore)
Relocalization may be the most important strategy for minimizing climate change. According to Bill McKibben, “working as communities is the most important thing that we can be doing right now.” In this wide-ranging conversation about the sustainability of our civilization, McKibben shares his thinking about much more than climate change, including the fact that having “more” is not necessarily the key to our happiness. Bill McKibben has played a major role in public awareness and discussion about climate change. His 1989 book, The End of Nature, was likely the first book for a general audience about climate change. He’s one of the founders of the planet-wide, grassroots climate change movement, 350.org, he spearheaded resistance to the Keystone Pipeline, and launched the fossil fuel divestment movement. Local food, small farms, suburban isolation, more leisure and less stuff, community connections, and greater satisfaction all come up for discussion. Dave Gardner sat down with McKibben in 2007, shortly after publication of his book, Deep Economy: The Wealth of Communities and the Durable Future, the year before he co-founded 350.org, for this macro-level look at climate change, human behavior and happiness, and public policy. We're sharing encore episodes from Season One while we take a break between seasons two and three.

Predictably Irrational: Dan Ariely (#114 Encore)

Predictably Irrational: Dan Ariely (#114 Encore)
Do we behave rationally? You might be surprised how often our decision-making deviates from what is in our best interest. Behavioral economist Dan Ariely studies human behavior and decision-making. His experiments have led him to startling conclusions.    “We repeatedly and predictably make the wrong decisions in many aspects of our lives.”   We may be rats in a maze for scientific study, but Dan Ariely puts a refreshingly human face on the scientific study of why we do the things we do. He offers an insightful explanation of why Republicans and Democrats in the U.S. can't agree on facts:   “When we have an initial belief, reality doesn’t matter as much as we think.  We have an illusion that we’re actually observing reality, but it’s filtered dramatically by what we’re experiencing in our brains, and our expectations.”   Ariely offered this about climate change: “If you were starting from scratch, and you said, ‘Let me create a problem that people would not care about,’ it would look very much like global warming.” Listen to this conversation to find out why. This fun and fascinating dialogue explores the decoy effect, inter-temporal choice, hedonic treadmill, identifiable victim effect, behavior substitution, the happiness conundrum, keeping up with the Joneses, and even being choosy about who you compare yourself too. It’s a fascinating journey into the human psyche. NOTE: We are between Season 2 and Season 3. For the next several weeks we’ll bring you encore episodes from the first season of Conversation Earth. Season 3 is in the works. Thanks for listening, and thank you for visiting http://tinyurl.com/ceseason3 and pitching in to make the next season possible.

Behaving Against Our Interests: Paul Ehrlich (#110 Encore)

Behaving Against Our Interests: Paul Ehrlich (#110 Encore)
Today it could be argued that human beings daily act against our own self-interests. How? Biologist Paul Ehrlich and fellow scientists tell us we are expanding our population and economy beyond the Earth's carrying capacity - at our peril.  Why do we insist on continuing? Ehrlich has been a keen observer of human behavior for over 50 years, and he thinks “we need a millennium assessment of human behavior.” If we can understand how we behave, and why we behave that way, perhaps we can figure out how to behave as though we want to hang around another thousand years. We're sharing the best episodes from Season One while we take a break and fundraise for Season Three. Please check out our story and pitch in a little at http://tinyurl.com/ceseason3 to make sure the series continues.   Ehrlich is best known for authoring The Population Bomb, published in 1968 at the suggestion of the Sierra Club’s first executive director, David Brower. Paul’s wife, Anne Ehrlich, co-authored the book (though the publisher insisted only Paul’s name adorn the book). Paul and Anne preferred a different title, Population, Resources and Environment, as the book was about much more than human population. The book offered dramatic warnings about the impact of the expanding scale of the human enterprise, which included not just the number of people on the planet, but also their behavior – levels of consumption and the size of their economies.   Growth boosters have criticized Paul Ehrlich since the 1960s. Some claim his ideas have been disproved and discredited, but generally those detractors have been economists (and not all economists). Ehrlich is a serious scientist with an impressive command of the facts, and the scientific community continues to publish and devour his work. His frank and direct approach, and colorful way with words, have continued to make him a lightning rod for discussion of a question that is central to the notion of sustainability of human civilization:    Can technology and innovation perpetually expand the carrying capacity of our planet?   In this 2007 interview, only very brief portions of which have ever been released, Paul Ehrlich shares his opinions on population, economics, hunger and poverty, and climate change. He takes aim at politicians, economists, television news, and human beings in general.   “It’s not a matter of needing more science to know what do.  We can use more science, but the big problem is why is there such a gap between what the scholarly community knows and what the politicians and public know and are willing to do anything about.” Learn more about Ehrlich, find links to his work, and learn more about the series at http://www.conversationearth.org

Running on Empty: Rex Weyler (#109 Encore)
Rex Weyler has lived the life dreamed of by those who want to make a difference. As a young man he joined early Greenpeace expeditions to document and stop commercial whaling. He went on to co-found Greenpeace International, and as a journalist has covered the subject of ecology extensively. We're sharing the best episodes from Season One while we fundraise for Season Three. Check out our story at http://tinyurl.com/ceseason3 . Your tax-deductible donation fuels this non-profit project. “The human machine is just steamrolling…toward disaster.” Weyler has lived a rich life and has a keen understanding of the source of joy, but there is sadness in his voice when he talks about how civilization grew right past ecological limits to growth. “I'm not concerned that my children will consume less stuff and have to live lifestyles more like my grandparents. I'm more concerned that my children will have to live in chaos because we were stupid and we tried to drive right past all these limits….” In this newly released 2010 interview, Weyler shares his observations of “what can happen as a civilization grows out of control.” Technology, economics, consumption, population and politics are all in his cross-hairs. Weyler does express some hope for the future, as well, and outlines changes needed to bring human civilization back to living within ecological limits. “What I'm working toward in my life and in my community is that we make these changes intelligently, peacefully, within our communities.” Learn more at http://www.conversationearth.org
Cornucopian Myth: William Catton (#107 Encore)

Cornucopian Myth: William Catton (#107 Encore)
“The age of growth and the age in which growth is going to be considered a good thing is coming to an end.” The late sociologist William R. Catton was certain of this, but spent a significant portion of his professional life attempting to understand why mainstream society was reluctant to prove his point.   Catton authored the landmark book, Overshoot: The Ecological Basis of Revolutionary Change, published in 1980. He brought important sociological perspective to a subject dominated by biologists and physicists. He observed that our lives are built around an obsolete cultural belief system, developed when the size of human civilization had not yet outgrown the carrying capacity of the planet.   According to scientists at the Global Footprint Network, human civilization surpassed a sustainable scale (a combination of population and consumption) in the 1970s. Catton observed a lag between that reality and the dominant worldview that affects our rate of consumption – of both renewable and nonrenewable resources. Bill Catton passed away on January 5, 2015. At the time of my conversation with Bill Catton, he had just published his third book, Bottleneck: Humanity's Impending Impasse.
