To achieve lasting change sometimes requires the hard, even radical, choice of partnering with people you'd least expect. Justice reform advocate Nisha Anand shares her story of working with her ideological opposite to make history and save lives -- and urges us all to widen our circles in order to make progress with purpose.

"The good news is it's now clearly cheaper to save the planet than to ruin it," says engineer and investor John Doerr. "The bad news is: we are fast running out of time." In this conversation with climate policy expert Hal Harvey, the two sustainability leaders discuss why humanity has to act globally, at speed and at scale, to meet the staggering challenge of decarbonizing the global economy (which has only ever increased emissions throughout history) -- and share helpful examples of promising energy solutions from around the world.

Rituals for the dead span much of the natural world, seen in practices from humans and elephants to bees, dolphins and beyond.

The clash of ideas is fundamental to creativity and progress, but it can also be deeply destructive and create divisions within companies, communities and families. How do you foster productive debate while protecting against harmful speech and misinformation? Constitutional lawyer Ishan Bhabha lays out structures that organizations can use to navigate ideological disagreement and responsibly bring facts and context to a larger dialogue.

"This decade is a moment of choice unlike any we have ever lived," says Christiana Figueres, the architect of the historic 2015 Paris Agreement. The daughter of Costa Rica's beloved President José Figueres Ferrer, she shares how her father's unwillingness to lose the country he loved taught her how stubborn optimism can catalyze action and change. With an unshakeable determination to fight for the generations that will come after us, Figueres describes what stubborn optimism is (and isn't) -- and urges everyone to envision and work for the future they want for humanity.

Sometimes, a single decision can change the course of history. Join journalist and author Isabel Wilkerson as she tells the story of the Great Migration, the outpouring of six million African Americans from the Jim Crow South to cities in the North and West between World War I and the 1970s. This was the first time in American history that the lowest caste people signaled they had options and were willing to take them -- and the first time they had a chance to choose for themselves what they would do with their innate talents, Wilkerson explains. "These people, by their actions, were able to do what the powers that be, North and South, could not or would not do," she says. "They freed themselves."

During publicity interviews for The 99% Invisible City someone asked us, “What is your favorite way to experience the city?” The answer is walking. If you have nothing to do, take a walk. If you are overwhelmed with things to do, take a walk. We’ve been working so hard on the book release and new miniseries we’re launching in December that we’re going to take a walk with our friends at Pop Up Magazine. Pop Up Magazine's team spent weeks interviewing dozens of people about walking, including Jenny Slate, Anna Sale (Death, Sex & Money), Antwan Williams (Ear Hustle), author and radio host Lulu Miller, writer Sam Jay (Saturday Night Live), NASA Astronaut Drew Feustel, Sergeant Julian Torres, and many others.

Our food systems have not been designed to adapt to major disruptions like climate change, says environmental journalist Amanda Little. In this eye-opening talk, she shows how the climate crisis could devastate our food supply -- and introduces us to the farmers, entrepreneurs and engineers who are radically rethinking what we grow and how we eat, combining traditional agriculture with state-of-the-art technology to create a robust, resilient and sustainable food future.
