    Ivy Insights

    The Shape of the World podcast is a hidden gem among environment-based podcasts. As someone who typically doesn't seek out these types of podcasts, I was pleasantly surprised by how thoroughly enjoyable it was. This podcast covers a range of interesting topics and manages to avoid the drone that can sometimes be found in educational podcasts. It also provided me with a newfound knowledge, as I discovered that I had been incorrectly referring to multiple octopus as "octopi."

    One of the best aspects of The Shape of the World is its ability to bring hope and honest conversations about our world. The podcast features diverse and interesting voices, providing a refreshing perspective on environmental issues. The host, Jill, asks all the right questions during interviews, making each episode both informative and engaging. The educational aspect of this podcast is top-notch, leaving listeners feeling inspired and motivated to make positive changes in their own lives.

    Another standout aspect of this podcast is its appeal to a wide range of interests. Whether you're into science, nature, the environment, or even art, The Shape of the World has something for everyone. The content is not only interesting but also inspiring and informational. Each episode invites listeners to explore different facets of our world and learn something new along the way.

    While it may be difficult to find any faults with this podcast, one potential downside could be its narrow focus on environmental topics. If you're looking for a more diverse range of subject matter in your podcasts, this may not be the best fit for you. However, if you have an interest in cities or nature specifically, this is definitely a must-listen.

    In conclusion, The Shape of the World podcast is an incredibly well-done production that offers insightful conversations about the nature that surrounds our cities. Jill Riddell's talent for interviewing shines through as she engages with each brilliant mind featured on the show. With its mix of education and inspiration, this podcast leaves a lasting impact on its listeners. Both seasons are binge-worthy, and I highly recommend giving this podcast a listen if you want to expand your knowledge and appreciation of the world around us.
