It's not easy being evergreen

The team peers into the Outside/Inbox to answer listener questions on the theme of “green,” a prompt which sends us exploring the hanging gardens of Babylon, xeriscaping, and the evolution of the human eye. 1: What’s the benefit of being evergreen? 2: How water-friendly is my lawn? 3: How many city buildings have green roofs? 4: Why did we evolve to see so many different shades of green? Featuring Georgia Silvera Seamans, Rubab Saher, Kate England, Abraham Wu, and Adriana Briscoe. Special thanks to Steven Peck.  How to submit a question to the Outside/Inbox Call our hotline, 1-844-GO-OTTER, and leave a voicemail. Send a voice recording to [email protected]. We also post regular call-outs for questions in our stories on Instagram. We’re seeking questions on a new theme for an upcoming episode: “the deeps.” Think caves, life underground, geothermal energy, and deep existential questions about our life on earth.    SUPPORT Outside/In is made possible with listener support.
