Emily is talking about whales again. Listen in to learn about one of the most endangered species on earth, what is being done, and some controversies surrounding it. The North Atlantic Right Whale is a struggling species, this episode dives into the reasons for their status, and the most recent information on this year's calves.

Let us close this ever-important month off with a spotlight on black conservationists that inspire us. This episode gives a short history of black people's place in North American and African conservation and hopes to give recognition to some incredible people who are helping change the world.

This week Clara and Emily travel to the lush nation of Columbia! In this beautiful country you'll find ugly river dolphins, condors, manatees and... cocaine hippos? Introduced by Pablo Escobar is the Columbian hippo, the worlds largest invasive species. Listen along to learn the difficulties of castrating a hippo, a strange take on rewilding, and why you shouldn't eat hippo meat.

Clara and Emily are taking root this year on new and interesting topics. Your favourite podcasters are back and here to share the wonders of Arbuscular Mycorrhizal Fungi (AMF), their fascinating punishment-reward relationship with plants, and how the agricultural industry can benefit from these fungi.

Radiation, and freezing, and drought oh my! Tardigrades are resistant to all this and more. Emily shows Clara the weird and wacky side of scientific studies including one that shot tardigrades out of a gun. To learn about the only animal that can (BEAR-ly) survive in space, make sure to listen to this week's episode of right up your algae.
