Bernie Krause has been recording the wild â€” the wind in the trees, the chirping of birds â€” for 45 years. He has seen many environments radically altered by humans, sometimes even by practices thought to be environmentally safe.
Sustainability consultant Jane Poynter tells her story of living two years and 20 minutes in Biosphere 2, a hermetically sealed environment in Arizona. The experience provoked her to explore how we might sustain life in the harshest of conditions.

The news that Microsoft co-founder Bill Gates now says it was a mistake to long ago force Windows PC users to type "Ctrl-Alt-Delete" at start-up is getting tons of attention because his public mea culpas are rather rare.
This may be premature, but it is best to think of this post as an obituary for the BlackBerry, a phone struck down seemingly in its prime. Gone so soon.
BB, we'll miss you.
Over the course of its existence, BlackBerry sold smartphones to more than 200 million people. It became ubiquitous in places like Indonesia, but it began with an invasion of Wall Street and Washington.
During an experiment, marketing professor Remi Trudel noticed a pattern in what his volunteers were recycling versus throwing in the garbage. He then went through his colleagues' trash and recycling bins at Boston University for more data.
He found the same pattern, says NPR's Shankar Vedantam: "Whole sheets of paper typically went in the recycling, but paper fragments went in the trash."
Same type of paper, different shapes, different bins.
Los Angeles Unified School District started issuing iPads to its students this school year, as part of a $30 million deal with Apple. The rollout is in the first of three phases, and ultimately, the goal is to distribute more than 600,000 devices.
One thing you can say about the diminutive speckled sea louse: it's always on time.
Scientists studying the tiny crustacean, a marine cousin of the wood-louse, found that it runs not one, but two internal clocks. Not only does the creature have a circadian rhythm, or so called "body clock" like most land-dwelling animals, including humans, but it also has a circatidal clock that follows the 12.4-hour cycle of the tide.
The Internet, from its inception, has been embraced as a great democracy, a leveler, a town square. Upload a video, like a friend's status, write a comment about an article you read, insert your thoughts here. Well, you can no longer do that on the Popular Science magazine website, Popsci.com. It announced on Tuesday that comments can be bad for science.
And joining us to explain more about the decision is Jacob Ward, editor and chief of Popular Science magazine. Welcome to the program.
The technology world is reeling. That's after press reports earlier this month that the National Security Agency may have weakened computer software. The reason, to make it easier for the government to read encrypted messages. The stories have upset many encryption experts, the very people who help scramble digital communications to keep those messages secure.
