In Australia, conventional conservation wisdom has stated that in order to save the small indigenous mammals, it's necessary to kill invasive predators. But is it?  Today on the show, we follow environmental writer Emma Marris as she explores the concept, and possible limits, of compassionate conservationism.

Also, are you noticing that we're in your feed a little early? That's because this month, we're asking for you to pitch in and support the podcast with a donation, and because we know that's kind of annoying, we want to give you something a little extra as thanks. So for the month of April, instead of just 2 episodes, we're going to give you four.

Not only that we're giving away swag! We've lined up a bunch of nifty thank you gifts, which you can peruse at outsideinradio.org

So, if you want to send a little love our way click here to donate to our Outside/In Fund Drive, and get a limited edition O/I button (among other cool stuff)!
