One of our listeners is in a pickle. He’s looking to buy an engagement ring but wants to make sure the diamond comes from an ethical and sustainable source. So he sent us an email asking for help.

This is our latest addition of “This, That, or the Other Thing.” It's a series about the choices we make in our lives to try and build a more sustainable world, whether they have any effect, and what we can do instead if they don't.

Today… Host Nate Hegyi looks into the most sustainable ways to source that big, sparkly rock. Should it be a diamond from the ground? A diamond grown in a lab? Or maybe a different gemstone altogether?

Featuring Saleem Ali, Rachelle Bergstein and Anna Provost.

Produced by Nate Hegyi. For full credits and transcript, visit outsideinradio.org.

The Kimberley Process helped reduce the number of conflict diamonds in the world – here’s a list of countries that are participants.

Anna Provost features a lot of her really cool Montana-mined sapphires on Instagram.

A recent study in the journal Nature found that mining diamonds produces millions times more greenhouse gas emissions than growing them in a lab.

Alexis Nikole Nelson, better known to her millions of fans as @blackforager, was raised by a mother who is an avid gardener and a father who loves to cook. Foraging allowed Alexis to fuse her love for wild plants and food from a very young age.

But before Alexis became the @blackforager many know today, there was a period in her life where Alexis lost that love and connection to foraging, and where food became very much the enemy.

This episode comes to us from our friends at Going Wild with Dr. Rae Wynn-Grant, a podcast about the human drama behind saving animals. From a paleoanthropologist who hunts fossils in conflict zones, to someone who helped save an endangered species while in prison, show host and wildlife biologist Dr. Rae Wynn-Grant takes us inside the work of the extraordinary people who are protecting wildlife.

Featuring Alexis Nikole Nelson.

Mike Strizki drives the only hydrogen-powered car on the East Coast. That’s because he’s the only person with access to fuel… which he makes, by himself, in his backyard in New Jersey.

And it’s not just his car. Mike’s house, his lawnmower, even his bicycle are all powered by hydrogen. He’s convinced that this element could be the single most important solution to the climate crisis, if only people and governments would just get on board.

But he’s been screaming this from the rooftop of his hydrogen house for two decades. And today, fewer than 0.2% of cars in the US run on hydrogen. What’s it like to be the earliest early adopter of a technology that never catches on? And does Mike still have a chance to be proven right?

In the race to decarbonize cars, battery electric vehicles have proven more popular than hydrogen. But debate still rages on which is the better zero-emission technology. Some say hydrogen cars cannot catch up to battery-electric vehicles, whereas others claim EVs aren’t the future, hydrogen is.

Mike Strizki and his hydrogen-powered house have been featured on The Wall Street Journal, ABC World News, and a number of New York Times articles including “The Zero-Energy Solution,” and “The Gospel of Hydrogen Power.”
