Check the website here: http://enlites.com/ Dr. Rodolfo Dirzo is Associate Dean at the Doerr School of Sustainability, Bing Professor in Environmental Science, Professor of Earth System Science and Senior Fellow at the Woods Institute for the Environment at Stanford University. His scientific work examines the study of species interactions in tropical ecosystems from California, Latin America, and other tropical areas of the world. Recent research highlights the decline of animal life (“defaunation”), and how this affects ecosystem processes/services (e.g. disease regulation). In this episode, we first talk about species interactions, and the role they play in evolution. We also talk about hybrid networks, and how they can be disrupted by human activity. We discuss why biodiversity conservation is so important, and how climate change impacts animal populations. We then talk about mass extinctions, and we focus on the ongoing sixth mass extinction. Finally, we discuss the signs that the sixth mass extinction is the result of human activity, and how it can impact humans. -- A HUGE THANK YOU TO MY PATRONS/SUPPORTERS: PER HELGE LARSEN, JERRY MULLER, HANS FREDRIK SUNDE, BERNARDO SEIXAS, OLAF ALEX, ADAM KESSEL, MATTHEW WHITINGBIRD, ARNAUD WOLFF, TIM HOLLOSY, HENRIK AHLENIUS, JOHN CONNORS, FILIP FORS CONNOLLY, DAN DEMETRIOU, ROBERT WINDHAGER, RUI INACIO, ZOOP, MARCO NEVES, COLIN HOLBROOK, PHIL KAVANAGH, SAMUEL ANDREEFF, FRANCIS FORDE, TIAGO NUNES, FERGAL CUSSEN, HAL HERZOG, NUNO MACHADO, JONATHAN LEIBRANT, JOÃO LINHARES, STANTON T, SAMUEL CORREA, ERIK HAINES, MARK SMITH, JOÃO EIRA, TOM HUMMEL, SARDUS FRANCE, DAVID SLOAN WILSON, YACILA DEZA-ARAUJO, ROMAIN ROCH, DIEGO LONDOÑO CORREA, YANICK PUNTER, ADANER USMANI, CHARLOTTE BLEASE, NICOLE BARBARO, ADAM HUNT, PAWEL OSTASZEWSKI, NELLEKE BAK, GUY MADISON, GARY G HELLMANN, SAIMA AFZAL, ADRIAN JAEGGI, PAULO TOLENTINO, JOÃO BARBOSA, JULIAN PRICE, EDWARD HALL, HEDIN BRØNNER, DOUGLAS FRY, FRANCA BORTOLOTTI, GABRIEL PONS CORTÈS, URSULA LITZCKE, SCOTT, ZACHARY FISH, TIM DUFFY, SUNNY SMITH, JON WISMAN, DANIEL FRIEDMAN, WILLIAM BUCKNER, PAUL-GEORGE ARNAUD, LUKE GLOWACKI, GEORGIOS THEOPHANOUS, CHRIS WILLIAMSON, PETER WOLOSZYN, DAVID WILLIAMS, DIOGO COSTA, ANTON ERIKSSON, CHARLES MOREY, ALEX CHAU, AMAURI MARTÍNEZ, CORALIE CHEVALLIER, BANGALORE ATHEISTS, LARRY D.

A renowned scientist and environmental advocate looks back on a life that has straddled the worlds of science and politics. Acclaimed as a public scientist and as a spokesperson on pressing environmental and equity issues, Paul R. Ehrlich reflects on his life, from his love affair with his wife Anne, to his scientific research, public advocacy, and concern for global issues. Interweaving the range of his experiences—as an airplane pilot, a desegregationist, a proud parent—Ehrlich's offers valuable insights on pressing issues such as biodiversity loss, overpopulation, depletion of resources, and deterioration of the environment. A lifelong advocate for women's reproductive rights, Ehrlich also helped to debunk scientific bias associating skin color and intelligence and warned some 50 years ago about a possible pandemic and the likely ecological consequences of a nuclear war. His new book Life: A Journey Through Science and Politics, focuses on the human predicament, including problems of governance and democracy in the 21st century, and insight into the ecological and evolutionary science of our day. It is a must-read for anyone interested in understanding global change, our planet's wonders, and a scientific approach to the present existential threats to civilization. Paul Ehrlich is the Bing Professor of Population Studies, Emeritus, and president of the Center for Conservation Biology at Stanford University. He has carried out field, laboratory and theoretical research on the dynamics and genetics of insect populations, the evolutionary interactions of plants and herbivores, the behavioral ecology of birds and reef fishes, the effects of crowding on human beings, human cultural evolution, and health problems related to industrialization. He is author and co-author of more than 1,100 scientific papers and articles and more than 40 books. Ehrlich is a member of the U.S. National Academy of Sciences, the American Philosophical Society and a Foreign Member of the Royal Society. Among his many other honors is the Royal Swedish Academy of Sciences, Crafoord Prize. He has appeared on more than 1,000 TV and radio programs and was a correspondent for NBC News.

We discussed recent developments in the ongoing Mass Extinction Event, including co-extinctions and the potential reduction of the aerosol masking effect as the worldwide insurance industry teeters on the brink.
Introduction We have had multiple “existential threats” over the centuries, yet here we still are, alive and well, and listening to the dire warnings about yet another end-of-the-world threat. Are we listening to a resurrected Chicken Little screeching about how The Sky is Falling, or is the threat for real this time? That is the subject of today’s 10-minute episode. Continuing To the best of everyone’s knowledge, only one existential threat has ever visited our planet, and that was when the dinosaurs were wiped out. I’m with the group that blames asteroids. If for no other reason than asteroids are not a protected group, and have not hired lawyers. More recently, various wars and their new technologies have been seen as life-on-earth-ending threats. In WWI, poison gas and machine guns were seen that way. In WWII, the airplane, perhaps especially long-range, high-capacity bombers, were seen as a dire threat. In both world wars, the major concern of those issuing the threats was the new technology's ability to wipe out civilian populations on a widespread basis. And the atomic bomb, used almost 75 years ago, caused even more catastrophic predictions. In 1963, post Korean War, and prior to Vietnam, Bob Dylan wrote and performed his haunting song, “Masters of War”. Let’s look at some of the lyrics: “You've thrown the worst fear That can ever be hurled Fear to bring children Into the world For threatening my baby Unborn and unnamed You ain't worth the blood That runs in your veins” From this then popular song, we can see that climate change worriers are far from the first to claim that a threat is so dire that not having children is the preferred path. “Fear to bring children into the world.” Do you suppose that any would-have-been parents went childless because of the anti-war viewpoint in Dylan’s song? “Masters of War” remained very popular throughout and past the Vietnam War. Anti-war sentiment and distrust of “the man” was at least as strong as today’s climate change furor and the distrust of anyone who disagrees. Well before Dylan, Thomas Malthus, an English cleric and scholar, influential in the fields of political economy and demography in the late 1700s, wrote: “That the increase of population is necessarily limited by the means of subsistence, That population does invariably increase when the means of subsistence increase, and, That the superior power of population is repressed by moral restraint, vice and misery.” In other words, Malthus was convinced that we were going to run out of food for the expanding population and starve. In 1800, there were 1 billion people; today we are close to 8 billion. And we have more food per person than ever. In the same vein, in 1968, Paul R. Erlich, an American biologist, and the Bing Professor of Population Studies in the Department of Biology at Stanford University, and president of Stanford's Center for Conservation Biology, wrote “The Population Bomb.” Here’s a quote, "The battle to feed all of humanity is over. In the 1970s hundreds of millions of people will starve to death in spite of any crash programs embarked upon now. At this late date nothing can prevent a substantial increase in the world death rate.” Does Erlich’s prediction of imminent death on a global scale have a familiar ring? Ah, and let’s not forget the peak oil existential threat. More recent than the unfounded Erlich scare, the peak oil crowd was claiming that we were going to run out of oil; lights would go out, gas would go to $25 a gallon--disaster! The idea was that we knew about all the oil there was to know about, and with increasing use, we would run out--in about 10-12 years from then. And, by the way, America was going to become a nation subject to the whims of the oil-rich countries, because we would need to import a greater and greater percentage of our oil consumption. We were addicted to oil, and OPEC was our pusher.
This month's show features Dr. Paul Ehrlich for the third time on Nature Bats Last. Dr. Ehrlich is the Bing Professor of Population Studies in the Department of Biology of Stanford University and president of Stanford's Center for Conservation Biology (https://ccb.stanford.edu/paul-r-ehrlich). He is a renowned biologist and ecologist best known for his warnings about the consequences of human population growth.
In their 1968 book The Population Bomb, Paul and Anne Ehrlich warned of the dangers of overpopulation. These included mass starvation, societal upheaval and environmental ruin. This and other dire predictions about humankind earned Ehrlich a reputation as a prophet of doom, and fifty years later he doesn’t see much in the way of improvement. Harvard cognitive psychologist Steven Pinker, on the other hand, prefers to look on the bright side: people are living longer, extreme poverty has been decreasing globally, worldwide literacy is on the rise. Is the glass half empty, or half full? Guests: Steven Pinker, Johnstone Professor of Psychology, Harvard University; author, “Enlightenment Now: The Case for Reason, Science, Humanism, and Progress” (Penguin, 2018) Paul R. Ehrlich, Bing Professor of Population Studies, Stanford University; co-author, “The Population Bomb” (Ballantine, 1968)
“The agricultural and industrial revolutions transformed the entire biosphere … now we humans are paying a high price for it.� Returning guest Dr. Paul Ehrlich, along with co-author Dr. Sandra Kahn, serves us a dose of reality in his new book, Jaws: The Story of a Hidden Epidemic. From mouth-breathing to heart disease and depression, we’ll look at the science of how and why our health is impacted, and what – if anything – we can do about it. Dr. Ehrlich, Ph.D., is Bing Professor of Population Studies Emeritus and President of the Center for Conservation Biology at Stanford University. A member of the National Academy of Sciences and a recipient of numerous international honors, he investigates a wide range of topics in population biology, ecology, evolution, human ecology, and environmental science. Dr. Sandra Kahn, D.D.S., M.S.D., has 25 years of clinical experience in orthodontics and is part of craniofacial anomalies teams at the University of California, San Francisco and Stanford University. Later, Outstanding Health: A Longevity Guide for Staying Young, Healthy, and Sexy for the Rest of Your Life , introduces six steps you can use to achieve a healthier, happier lifestyle at home. Author Michael Galitzer, M.D., has worked for decades on his unique blend of conventional and complementary medicine, helping patients gain control of their health and stave off sickness. Dr. Galitzer, M.D., is a nationally recognized expert in energy medicine, integrative medicine, and bioidentical hormone replacement therapy (BHRT). For more than 40 years, he’s been an innovator in the field of longevity and anti-aging medicine.
In 1968, the best-seller “The Population Bomb,” written by Paul and Anne Ehrlich (but credited solely to Paul) warned of the perils of overpopulation: mass starvation, societal upheaval, environmental deterioration. The book was criticized at the time for painting an overly dark picture of the future. But while not all of the Ehrlich’s dire predictions have come to pass, the world’s population has doubled since then, to over seven billion, straining the planet’s resources and heating up our climate. Can the earth continue to support an ever-increasing number of humans? On its 50th anniversary, we revisit “The Population Bomb” with Paul Ehrlich. Guest: Paul R. Ehrlich, President, Center for Conservation Biology, Bing Professor of Population Studies, Stanford University; co-author, “The Population Bomb” (Ballantine, 1968) This program was recorded at Stanford University.
My guests today are Dr. Sandra Kahn and Professor Paul Ehrlich. Dr Kahn is a graduate from the University of Mexico and the University of the Pacific in San Francisco CA. She has 25 years of clinical experience in orthodontics and has been part of several craniofacial anomalies teams. She has done graduate work in the area of physical anthropology at the University of California in Berkeley and recently retired from traditional orthodontics to focus on Airway Centric orthodontics and pediatric Obstructive Sleep Apnea prevention using Forwardontics. Her approach is to promote harmony of the jaws… not just straightening teeth. Paul Ehrlich is Bing Professor of Population Studies Emeritus & President of the Center for Conservation Biology at Stanford University as well as Adjunct Professor at University of Technology Sydney. Professor Ehrlich is author and coauthor of more than OneThousand scientific papers and articles and over 40 books. He is best known for his efforts to alert the public to the many intertwined drivers that are pushing humanity tow
Paul Ehrlich is the Bing Professor of Population Studies of the Department of Biology at Stanford University and president of Stanford's Center for Conservation Biology. In this episode, Paul and I discuss the very severe loss of biodiversity on this planet in recent decades, human civilization and its detrimental impact on animal and insect populations, abrupt climate change, the toxification of the environment, the looming spectre of nuclear war, as well as the psychological blind-spots in the individual and collective human psyche that allows for this massive level of destruction to take place without much attention and meaningful change to ensure our collective survival.
