For generations, everything has been getting faster, better, and cheaper. Finally, we reached the point that almost anything you could ever want could be sent to your home within days - even hours - of when you decided you wanted it. America made that happen, but now America has lost interest in keeping it going.

This radio dramatization of the classic movie is introduced by its director, Frank Capra, and features James Stewart re-creating his Oscar-nominated role. It aired on May 8, 1949.

Bill Gates shares what he's learned in more than a decade of studying climate change and investing in innovations to address the problems, and sets out a vision for how the world can build the tools it needs to get to zero greenhouse gas emissions. Bill Gates explains why he cares so deeply about climate change and what makes him optimistic that the world can avoid the most dire effects of the climate crisis. Gates says, "We can work on a local, national, and global level to build the technologies, businesses, and industries to avoid the worst impacts of climate change."

Just as World War II called an earlier generation to greatness, so the climate crisis is calling today's rising youth to action: to create a better future. In Unstoppable, Bill Nye crystallizes and expands the message for which he is best known and beloved. That message is that with a combination of optimism and scientific curiosity, all obstacles become opportunities, and the possibilities of our world become limitless.

In this remarkable challenge to conventional thinking about the environment, David Owen argues that the greenest community in the United States is not Portland, Oregon, or Snowmass, Colorado, but New York City.

Waste. We spend a great deal of energy trying to avoid it, but once you train your eyes to look for it, you’ll see it all around you - in your home, your business, and your everyday life. In Wasted, futurist Byron Reese and entrepreneur Scott Hoffman take readers on a fascinating journey through this modern world of waste, drawing on science, economics, and human behavior to envision what a world with far less of it - or none of it at all - might look like.

Through an unforgettable cast of characters, Pulitzer Prize-winning author Richard Rhodes explains how wood gave way to coal and coal made room for oil, as we now turn to natural gas, nuclear power, and renewable energy. Rhodes looks back on five centuries of progress, through such influential figures as Queen Elizabeth I, King James I, Benjamin Franklin, Herman Melville, John D. Rockefeller, and Henry Ford.

Jeff Speck has dedicated his career to determining what makes cities thrive. And he has boiled it down to one key factor: walkability. The very idea of a modern metropolis evokes visions of bustling sidewalks, vital mass transit, and a vibrant, pedestrian-friendly urban core. But in the typical American city, the car is still king, and downtown is a place that’s easy to drive to but often not worth arriving at. Making walkability happen is relatively easy and cheap; seeing exactly what needs to be done is the trick.

Take a look at the vehicle sitting in your driveway. It may be the last one you ever own. With an estimated 33 million fully autonomous cars and taxis projected to hit the road by 2040, an automotive renaissance is soon to be upon us. Personal car ownership currently costs the average sedan owner $9,000 annually. But car ownership may soon be a thing of the past.

Using interviews, data, and deep exploration of the hidden world of ports, traffic control centers, and the research labs defining our transportation future, acclaimed journalist Edward Humes breaks down the complex movements of humans, goods, and machines as never before, from increasingly car-less citizens to the distance UPS goes to deliver a leopard-printed phone case.

After water and air, sand is the natural resource that we consume more than any other - even more than oil. Every concrete building and paved road on Earth, every computer screen and silicon chip, is made from sand. And, incredibly, we're running out of it. The World in a Grain is the compelling true story of the hugely important and diminishing natural resource that grows more essential every day, and of the people who mine it, sell it, build with it - and sometimes, even kill for it.

In the twentieth century, wealth and power was dictated by access to oil. This century will have different kingmakers, perhaps different wars. We depend on a handful of metals and rare earths to power our phones and computers. Increasingly, we rely on them to power our cars and our homes. Whoever controls these finite commodities will become rich beyond imagining. Sanderson journeys to meet the characters, companies, and nations scrambling for the new resources.

The water coming out of your tap is four billion years old and might have been slurped by a Tyrannosaurus Rex. We will always have exactly as much water on Earth as we have ever had. Water cannot be destroyed, and it can always be made clean enough for drinking again. In fact, water can be made so clean that it actually becomes toxic. As Charles Fishman brings vibrantly to life in this delightful narrative excursion, water runs our world in a host of awe-inspiring ways, which is both the promise and the peril of our unexplored connections to it.

Twenty years ago, with The End of Nature, Bill McKibben offered one of the earliest warnings about global warming. Those warnings went mostly unheeded; now, he insists, we need to acknowledge that we've waited too long, and that massive change is not only unavoidable but already under way. Our old familiar globe is suddenly melting, drying, acidifying, flooding, and burning in ways that no human has ever seen.

The Colorado River is an essential resource for a surprisingly large part of the United States, and every gallon that flows down it is owned or claimed by someone. David Owen traces all that water from the Colorado’s headwaters to its parched terminus, once a verdant wetland but now a million-acre desert. He takes listeners on an adventure downriver, along a labyrinth of waterways, reservoirs, power plants, farms, fracking sites, ghost towns, and RV parks, to the spot near the US-Mexico border where the river runs dry.
