Episode Four:

pOTTERcast Part 2: Rats. Locusts. Sea otters?

For them, sea otters have destroyed their fisheries and destroyed their livelihoods. Learn more about this complex relationship and how the ecosystem has shifted with the growing presence of this top-level predator. (The music in this trailer is “Partly Sage” by Blue Dot Sessions, provided under the Attribution-Noncommercial License.)


Earthwatch depends on donations—above and beyond what we raise from volunteers who participate on our expeditions—in order to deliver our global conservation mission. In fact, volunteer contributions provide only half of the total resources Earthwatch needs to sustain over 40 field research expeditions, a wide variety of educational programs, corporate sustainability trainings, and more each year.
