When laws destroy nature

How many species even are there?

How many species are there on Earth? Marine biologist and taxonomist Manuel Caballero Gutierrez explains how scientists estimate global biodiversity, discover new species, and why humanity may currently know only around 25% of the life forms that exist on this planet. This episode of Green Frequency explores taxonomy, ocean exploration, extinction, climate change, and the long scientific process of naming and cataloguing species. From deep-sea expeditions and DNA analysis to museum archives and biodiversity conservation, the conversation reveals why understanding life on Earth is essential for protecting ecosystems and human society alike. Recorded live at The American University of Paris, with the full presentation video and slides available on YouTube.  Episode Guests: Dr. Manuel Callebar Gutierrez [https://www.aup.edu/profile/mcaballergutierrez] Browse Dr. Callebar Gutierrez’s publications on Research Gate [https://www.researchgate.net/profile/Manuel-Caballer-Gutierrez] WATCH THE FULL VIDEO ON YOUTUBE [https://youtu.be/u3d8UKgcAqM] Explore the Pine Forest Media [http://pineforestpods.com] digital ecosystem on our website [http://pineforestpods.com] Find the full-length video on YouTube @PineForestPods [https://www.youtube.com/@PineForestPods] Follow us on Social Media @pineforestmedia Audio Editing by Clark Marchese, Video Editing by Oscar Padula Videography and Set Design by Le Studio Du Passage [https://studiodupassage.com/] Cover Art by Laurel Wong [https://laurelawong.com/] Theme music by Nela Ruiz [http://nelaruizcomposer.com] Find some more Pine Forest Media podcasts below Listen to Oceanography on Spotify [https://open.spotify.com/show/6cg6LgAEvCP32rj24KixpP] or Apple Podcasts [https://itunes.apple.com/us/podcast/id1826543626?mt=2] Listen to Plastic Podcast on Spotify [https://open.spotify.com/show/4Iv20PynWeNKEZtq5O5UOj?si=MW-ZYI8zS0mUroec9T_lfA] or Apple Podcasts [https://podcasts.apple.com/us/podcast/plastic-podcast/id1737963995] Listen to South Pole on Spotify [https://open.spotify.com/show/292f9HcD3eCI2V6hLQG2Hi] or Apple Podcasts [https://itunes.apple.com/us/podcast/id1748730442?mt=2] Listen to Something in the Water on Spotify [https://open.spotify.com/show/5HGQytPxV6FfcX03OUBXYf?si=YszhS8C4ToafplCEsEErAQ] or Apple Podcasts [https://podcasts.apple.com/us/podcast/something-in-the-water/id1740586381] ---------------------------------------- Hosted on Acast.

When laws destroy nature

Colonial law helped shape modern deforestation. Legal historian Mariana Dias Paes explains how 19th-century property law, land dispossession, and colonial legal systems accelerated rainforest destruction in Brazil’s Atlantic Forest and continue to influence environmental conflicts today. This episode of Green Frequency explores colonialism, Indigenous land rights, private property, environmental history, and the legal foundations behind modern climate and conservation crises across the Atlantic world, including the Amazon and Congo rainforests. Recorded live at The American University of Paris, the conversation connects legal history to present-day environmental governance, climate justice, and biodiversity loss.

Science can't change the world on its own

We already understand many of the world’s biggest problems. So why are they still unsolved? A lot of the science is in. We know what is driving climate change, biodiversity loss, and pressure on global food systems. But knowledge alone does not create change. Somewhere between evidence and action, people have to make decisions. This episode explores that space. Using food systems as a case study, this conversation looks at what happens when science, policy, and lived experience meet. It asks who gets to shape solutions, how decisions are actually made, and why simple answers often fall short. Featuring Amanda Harding and Sarah Glavan of Convene, the discussion introduces the idea of deliberate dialogue. Carefully designed spaces where farmers, researchers, policymakers, and communities work through complex challenges together. Not by avoiding disagreement, but by working through it. Across this conversation: * Why scientific knowledge does not automatically translate into action * How power, culture, and politics shape environmental decision making * What science-policy-society interfaces actually look like in practice * Why listening may be just as important as producing evidence At the center of it all is a simple idea: Science can help us understand the world, But changing it requires something more human.

Drinking water and the complexity of sustainability

Water is simple to drink, but complex to understand. Water is essential to life, yet 2 billion people lack reliable access to clean drinking water. At the same time, millions of tons of plastic waste come from single-use bottles each year. So what actually makes water “sustainable”? Environmental scientist and water sommelier Dr. Elena Berg uses drinking water as a case study to unpack the complexity of sustainability from water sources and mineral content to local infrastructure, plastic use, and global inequality. Learn why not all water is the same, how small-scale “water farmers” approach stewardship, and why simple good vs bad narratives can be misleading. A deeper look at sustainability, environmental decision-making, and the hidden systems behind everyday choices.

What does climate justice even mean?

Climate justice explained: beyond emissions and policy. What does climate justice actually mean—and why is it so hard to define? This episode of Green Frequency breaks down climate justice as both a political and ethical challenge, not just an environmental one. Political scientist Dr. Rebecca Marwege explores how climate change reflects global inequalities, from coastal communities in Senegal to post-disaster recovery in New York. The conversation highlights why reducing emissions alone isn’t enough, and how adaptation, access to resources, and decision-making power shape real-world outcomes. Learn why interdisciplinary approaches, bringing together science, policy, and lived experience, are essential, and what can go wrong when they’re ignored. A clear, accessible introduction to climate justice, sustainability, and global climate policy.
