Guy's Favorites: What Is Original?
As we transition to our new host Manoush Zomorodi, Guy Raz looks back on some of his favorite episodes from his seven years hosting the TED Radio Hour. This episode originally aired on June 27, 2014. When is copying flattery, when is it thievery, and when is it sheer genius? In this hour, TED speakers explore how sampling, borrowing, and riffing make all of us innovators.

#548 Land and Ocean Conservation 101
This week we're talking about land and ocean conservation: what it means to protect our land and oceans, the complexities of competing interests and international boundries, and how well Canada is doing at conserving its most important wild areas. Helping us wrap our heads around it are National Parks Program Director Alison Ronson and National Oceans Program Director Candace Newman from the Canadian Parks and Wilderness Society (CPAWS). This episode is hosted by Rachelle Saunders.

Body Count
Right now, at this very moment, all across the planet, there are 7.6 billion human beings eating, breathing, sleeping, brushing their teeth, walking their dogs, drinking coffee, walking down the street or running onto the subway or hopping in their car, maybe reading a summary of a podcast they're about to hit play on ... and the number is only going up. Everyday 386,000 babies are born (16,000 an hour). We're adding a billion new people every 12 years. So here's a question you've probably never thought about: Are there more people alive right now than have ever lived on the planet in history? Do the living outnumber the dead? Robert got obsessed with this odd question, and in this episode we bring you the answer. Or, well, answers. This episode was reported by Robert Krulwich and produced by Annie McEwen and Pat Walters, with help from Neel Danesha. Fact-checking by Michelle Harris. Music and mixing by Jeremy Bloom.
