Listeners will hear from the world’s most renowned ocean explorer, a man who has dedicated his life to protecting penguins, a volcanologist who found a way to predict eruptions and a Peruvian biologist who is safeguarding sea life with the help of coastal communities. Taken together, the podcast will offer an intimate portrait of the diverse and dynamic people who are at the forefront of the quest to keep the planet perpetual.

😲🤯 She is a wonderful speaker! I know our oceans need help, not simply some help, but seriously massive amounts of help and now! I hear a lot of the "Is it useful?, IDK what it is so KILL it!". I drive about 12 miles round trip to the closest ♻️ location, which is nothing, I look at it like a nice little 15-20 min break for so me time! Shockingly for a fair ammount of selfish and stubborn people it is. That would be completely inconvenient. Dude! This entire moving, insanely scary, impossibly beautiful and living entity we call earth is amazing and you are incapable of giving a single second of your precious time to save it? Even to save yourself?! I also constantly pick up trash I see out exploring with my son and on weekends my partner joins in while home. But now I feel like a p.o.s😞. There needs to be ppl speaking out, we should all be! THANK YOU BOTH 💯👏👏👏 Thank you and every single person that TALKS about this. on a large scale such as this or maybe to your neighbors and co-worke
