If you like Whose Century Is It?, check out this preview of my new limited series podcast with the Global Reporting Centre, On China's New Silk Road.

Modern slavery in your grocery cart

Next time you sip your tea or bite into a bar of chocolate, or load up your grocery cart with other treats, spare a thought for the underpaid or unpaid workers who made it possible. Modern slavery comes in many guises, and politics professor Genevieve LeBaron of the University of Sheffield in England, who's done field studies on the subject, is here to tell you how it happens, and what you might want to look out for as you shop.

Wizards, Prophets & the Fate of the Earth

We're pretty clever, we humans, but we ignore unintended consequences at our peril -- like climate change, after a couple of centuries of fossil fuel-driven growth and innovation. Can we innovate our way out of that growing crisis, or must we cut back and conserve if we want a habitable planet? Or both? Science journalist and author Charles Mann, author of 1491, 1493 and The Wizard & the Prophet,tells the tale of these two competing approaches through the lives of the 'wizard,' Norman Borlaug, father of the Green Revolution, and the 'prophet,' William Vogt, early ecologist and author of the hugely impactful 1948 book,Road to Survival.

Sci Fi Future

In the imagined world of novelist Eliot Peper's near-term future in such books asBandwidth andBorderless,San Diego's burning, polar ice caps have melted, everyone's got their heads in their digital feeds, and a powerful social media company called Commonwealth controls --well, seems like just about everything. Eliot talks to host Mary Kay Magistad about writing speculative fiction, about the value of sci fi in helping us all think through current crises and possible futures, and about what sci fi has seen coming, and what it's gotten just plain wrong.

Why half the world's languages may disappear in this century

Embedded in each language is a reflection of life as lived by its speakers, over thousands of years. And when a language disappears, that embedded knowledge is lost. As the world grows more connected, and as dominant cultures push their own languages for wider use – think English, Chinese and Arabic, for starters -- languages are disappearing. As many as half the world's 7,000 languages may be gone by the end of the century. The good news is that linguists are on it, like this episode’s guest Laura Welcher, who oversees the Long Now Foundation’s Rosetta Project in San Francisco.
