Oceans are the next frontier of destructive human expansionism and extraction. Peruvian marine biologist and ocean life advocate, Daniel Cáceres Bartra, argues that human population growth and expansionism have already devastated nonhuman life on land, making it critical to protect the oceans before they suffer the same fate. From overfishing to deep-sea mining, Daniel advocates for top-down international action to protect marine life before humanity consumes the last great frontier of biodiversity. Highlights include:

• How Daniel became disillusioned with the fact that academic marine biology in Peru was captured by the commercial fishing industry and decided to pursue ecological advocacy;
• Why Daniel believes that 'waiting until we have enough science' to protect biodiversity means more species will experience population crashes and biodiversity loss;
• How Daniel's experience as a diver inspired him to protect life in the oceans before humanity decimates marine life as it has wildlife on land;
• Why the assumption that small-scale fishing means small-scale impacts on marine biodiversity is misguided;
• How the denial of small-scale fishing's impacts can also extend to the false assumption that indigenous groups, whose populations numbers and technological sophistication continue to grow, cannot also engage in overfishing;
• How deep sea mining threatens fragile ocean ecosystems and why resisting it offers a rare opportunity to stop an industry of destructive extraction before it begins;
• Why Daniel is a firm believer that, despite the fact that they're often not popular, international, top-down approaches are required to protect biodiversity;
• Why Daniel sees human overpopulation and the resulting human expansionism into virtually all ecosystems on Earth as inarguable ecological facts that explain much of our biodiversity crisis.

OVERSHOOT | Shrink Toward Abundance

OVERSHOOT tackles today's interlocked social and ecological crises driven by humanity's excessive population and consumption. The podcast explores needed narrative, behavioral, and system shifts for recreating human life in balance with all life on Earth. With expert guests from wide-ranging disciplines, we examine the forces underlying overshoot: from patriarchal pronatalism that is fueling overpopulation, to growth-biased economic systems that lead to consumerism and social injustice, to the dominant worldview of human supremacy that subjugates animals and nature. Our vision of shrinking toward abundance inspires us to seek pathways of transformation that go beyond technological fixes toward a new humanity that honors our interconnectedness with all beings.

Low-fertility alarmism is rampant in many countries. Who is and isn't encouraged to reproduce has always been a question of power in the US. Legal scholar Michele Goodwin traces a disturbing lineage from the forced breeding of enslaved women and the sterilization of primarily poor white women deemed genetically unfit to the very different reproductive choices available to women on the basis of race and class. She reveals how reproductive rights in the Roe era came to focus on abortion rights and failed to address broader reproductive injustices, especially the use of state power to police the wombs of Black and brown women. Highlights include:

• How Michele's visits to her relatives in the Deep South of the US in the 1970s, and seeing their lack of basic necessities like clean water or indoor plumbing, heightened her desire to address social injustice;
• How US pronatalism up until the Civil War was characterized by promoting reproduction of the enslaved girls and women for the sake of increasing the value of property;
• How the practice of 'hypodescent', or the one drop rule, in the US of determining blackness, allowed for the systematic and ongoing rape of Black women, while guaranteeing all their children remain property as slaves;
• How following the US Civil War, a fear of newly freed African Americans outnumbering the white population led to the implementation of coercive pronatalist policies pushing reproduction among white women;
• Why, with restrictive Jim Crow laws that maintained the low status of African Americans as the servant class, early 20th century eugenics, as marked by forced sterilization laws in the majority of US states, was primarily directed at poor white people deemed genetically unfit;
• How both Jim Crow laws and eugenics practices in the US became the primary models for Nazi Germany;
• How Michele's travels to India revealed the severe limitations on reproductive freedom of young women, with many resorting to becoming child brides, prostitutes, or gestational surrogates for survival;
• How Black women's pregnancies during the half century of Roe V. Wade abortion legality were marked by policing of low-birth weight babies and an assumption of drug use; whereas the mostly white IVF pregnancies and their offspring's low-birth weights were given broad cultural support;
• How the reproductive rights movement in the time of Roe became limited to abortion rights, driven primarily by the needs of white women, while ignoring larger issues plaguing Black women, such as lack of availability of sex education, contraception, and cancer screening.

"There is no alternative" is the story that keeps us trapped in a world that is unraveling. Jeremy Lent, author of Ecocivilization, imagines what becomes possible when we move away from competition, separation, and domination and trust grassroots democracy to build lives rooted in the collaboration, diversity, and mutualism found throughout nature and human history. As disenchantment with the dominant story grows, Jeremy discusses the alternatives already taking root that might provide the foundations for a future ecological civilization. Highlights include:

• How the worldview of separation from nature, beginning with sedentary agriculture and accelerating in the modern era, leads humanity to see nature as both a machine and as ripe for exploitation;
• How British and northern European elites enclosed and seized the commons, using law and force to dispossess people of their land and push them into wage labor; how this model of enclosure was exported around the world through colonialism; and how enclosure continues today through everything from patented seeds, state and corporate digital surveillance, and AI's enclosure of humanity's knowledge commons;
• How cultural hegemony, the cultural conditioning of peoples' mindsets, shapes what people believe is possible - convincing the majority that capitalism, economic growth, and existing systems serve everyone's interests and that we live in 'the best of all possible worlds';
• Why an ecological civilization would require moving from the primacy of capital to the recognition that people and other species have a right to flourish, and drawing its principles from life itself - including mutualistic symbiosis, heterogeneity, and diversity;
• How governance in ecocivilization should be grounded in subsidiarity and genuine participatory democracy, pushing decisions to the lowest feasible level and replacing today's electoral oligarchy with lottery-selected citizen juries and assemblies that have real-world power;
• How the mainstream panic over declining fertility rates reveals the continued cultural hegemony of the 'growth is good' story;
• Why, as dominant systems unravel, the emerging alternatives become 'islands of coherence' that attract increasing numbers of people, especially the young, who become disenchanted with the hollow promises of the dominant culture;
• Why the ultimate message of the book is the dethronement of TINA - There Is No Alternative - and why the unraveling of the dominant system creates an opportunity to reweave the social tapestry and build alternatives based on how human beings evolved to live, in cooperation with each other and the natural world.
