    Earth911 Podcast: Author Nadina Galle on The Nature of Our Cities
    Sep 16 2024
    More than half the world's population—4.4 billion people—live in cities today. That number is expected to rise to 80% by 2050. Our guest, Nadina Galle, is a trailblazing ecological engineer and author of The Nature of Our Cities. She is an ecological engineer who studies the intersection of nature and technology in urban environments. Nadina developed the concept of an Internet of Nature (IoN) that uses tools like artificial intelligence, automation, and sensors to support and enhance ecosystems within cities. Nadina's book offers a transformative perspective on how urban spaces can be reimagined in the face of climate change and sprawling development. She shares the inspiring story of the Groene Loper project in Maastricht, Netherlands, where soil sensors were deployed to monitor tree health. The results were remarkable, with trees supported by this technology growing up to three times larger than those without it. This is a powerful example of how technology can not only protect trees but also transform urban spaces into healthier, greener environments.

    From fire and the wheel to the reinforced concrete frames that define modern buildings, we are surrounded by technology. We tend to forget that technology emerged in response to nature — too often, we treated nature as the enemy, the chaos to be contained instead of recognizing that nature’s cycles and changes are the harmony we need to join to sustain society. The loss of any semblance of natural patterns, which ultimately leads to the depletion of the resources necessary for life, has inevitably led to the collapse of previous major civilizations. Modern society has more runway than previous societies because we have created a global economy, but that risks an even greater fall for our species when the ecological underpinnings of our prosperity collapse. The Nature of Our Cities is a powerful, straightforward, and emotionally resonant book to help you think through your role and choices in the restoration of nature. You can find it on Amazon or Powell's Books.

  • Earth911 Podcast: Cemvita’s Biotech Breakthroughs

    Earth911 Podcast: Cemvita’s Biotech Breakthroughs
    Sep 9 2024
    The global push for sustainability has reached a critical juncture, particularly in industries traditionally associated with high environmental impacts, such as chemical manufacturing and mining. These sectors, vital to the global economy, are also significant contributors to carbon emissions and environmental degradation. However, innovative approaches are beginning to transform how these industries operate, making sustainability not just an option but a driving force of innovation. On today's show, you'll meet and hear Tara Karimi, co-founder and Chief Scientific Officer of Cemvita. Tara and her brother, Moji, bring unique backgrounds -- Moji in petroleum engineering and she in biochemistry -- to the challenge of converting CO2 into the raw materials, known as feedstocks, for new chemicals, materials, and food products. They use of synthetic biology to turn a greenhouse gas into a useful resource. Cemvita’s breakthrough is just one of many CO2 capture and conversion strategies that could drastically reduce the carbon footprint of industries that are often criticized for their environmental impact.

    Cemvita applies biomimicry, the science of learning how nature acts to produce the cornucopia of life-supporting materials. The idea emerged in the early 1980s and now, 40 years later, we’re seeing not just occasional biomimetic innovation but potentially industry-transforming changes in strategy and environmental impact. There's a long way to go before, as Tara explains, we reach a carbon neutral and still prosperous economy. Cemvita’s approach, which combines organic and inorganic chemistry with the insight to see biomimetic alternatives to heat-intensive chemical refineries by, for instance, seeing a depleted oil well as a natural bioreactor to make gold hyrdogen or replacing leaching ponds filled with toxic chemicals with enclosed, non-toxic processing columns, point to just two of the paths out of our planet-killing industrial models.

  • Earth911 Podcast: Rachael Z. Miller Tracks Microfiber Pollution

    Earth911 Podcast: Rachael Z. Miller Tracks Microfiber Pollution
    Sep 2 2024
    Rachael Z. Miller is a leading voice in the fight against microfiber pollution, the plastic smog that trails our clothing like exhaust from a car. You might not see them, but our synthetic clothing sheds millions of tiny plastic fibers that make their way into our atmosphere, oceans, and rivers. It’s been less than a century since the introduction of synthetic textiles — nylon was the first about 90 years ago — but microfibers are already found everywhere on the planet, from the peaks of the Himalayas to the guts and bloodstreams of our bodies and those of mammals and marine life. As the founder of the Rozalia Project for a Clean Ocean, Rachael has dedicated herself to documenting and mitigating the impact of this invisible pollutant, including launching the Cora Ball, a laundry accessory that reduces the microfibers released during a wash.

    Rachael’s work shines a light on how something as simple as washing our clothes can have far-reaching consequences for ecosystems and wildlife, as the story she shared in a recent Earth911 explains: Polar Bears and Penguins Aren’t Wearing Our Clothes But They Might Be Eating Them. She’s also a National Geographic Explorer who has visited the Arctic and Antarctic to study the spread of microfibers. We discuss Rachael’s pioneering efforts to raise awareness, her innovative solutions, and what we can all do to reduce microfiber pollution in our daily lives. Tune in for a conversation that could change how you think about your laundry routine. You can find out more about Rachael and her work at https://www.rozaliaproject.org/
