What happens when you wear your own trash for 30 days?
You start a podcast. 



Welcome to Mama Earth Talk—a podcast for eco-curious individuals and conscious businesses who want to make a real difference, live lighter on the planet, and do it all without the pressure to be perfect.



I’m Mariska Nell, founder and host of Mama Earth Talk—a sustainability advocate, and passionate believer in progress over perfection. With a Master’s in Sustainable Design, postgraduate studies in Environmental Science, and years of hands-on experience, I’m here to help you take meaningful, heart-led action that works in real life. 



Mama Earth Talk shares an episode every second month packed with inspiring guest interviews, uplifting good news stories, and practical insights to keep you grounded and motivated. 



We also offer themed seasons, each diving deeper into specific topics like low-waste living, sustainable business, and planet-positive design—giving you the tools and inspiration to make real, lasting impact. 



Whether you're here to learn something new, feel inspired, or connect with a global community of changemakers—this space is for you. No guilt. No overwhelm. Just real talk, soulful progress, and hopeful stories—one small step at a time.
