Gas stoves are found in around 40% of homes in the United States, and they've been getting a lot of attention lately. A recent interview with Richard Trumka, the commissioner of the U.S. Consumer Product Safety Commission (CPSC), quickly became fodder for outrage, viral disinformation and political fundraising after he proposed regulating the appliance. The proposal stems from a growing body of research suggesting gas stoves are unhealthy — especially for those with asthma, chronic obstructive pulmonary disease and children. NPR climate and energy correspondent Jeff Brady joins us today to separate fact from fiction.

Today, we're going full nerd to talk about a new board game — Catan: New Energies. The game's goal is simple: Build and develop a modern-day island without catastrophically polluting it. Although the concept mirrors the effects of climate change, those words don't actually appear in the game. NPR correspondent Nate Rott talks to Emily about the thinking behind the new game and how the developers hope it can start conversations around energy use and pollution.

How The New Catan Board Game Can Spark Conversations On Climate Change

Ten years ago, Flint, Mich. switched water sources to the Flint River. The lack of corrosion control in the pipes caused lead to leach into the water supply of tens of thousands of residents. Pediatrician Mona Hanna-Attisha recognized a public health crisis in the making and gathered data proving the negative health impact on Flint's young children. In doing so, she and community organizers in Flint sparked a national conversation about lead in the U.S. water system that persists today. 

Today on the show, host Emily Kwong and science correspondent Pien Huang talk about the state of Flint and other cities with lead pipes. Efforts to replace these pipes hinge on proposed changes to the EPA's Lead and Copper Rule.

10 Years After Flint, The Fight To Replace Lead Pipes Continues

NPR's Tom Dreisbach is back in the host chair for a day. This time, he reports on a story very close to home: The years-long battle his parents have been locked in with the local wild beaver population. Each night, the beavers would dam the culverts along the Dreisbachs' property, threatening to make their home inaccessible. Each morning, Tom's parents deconstructed those dams — until the annual winter freeze hit and left them all in a temporary stalemate.

As beaver populations have increased, so have these kinds of conflicts with people...like Tom's parents. But the solution may not be to chase away the beavers. They're a keystone species that scientists believe could play an important role in cleaning water supplies, creating healthy ecosystems and alleviating some of the effects of climate change. So, today, Tom calls up Jakob Shockey, the executive director of the non-profit Project Beaver. Jakob offers a bit of perspective to Tom and his parents, and the Dreisbachs contemplate what a peaceful coexistence with these furry neighbors might look like.

Beavers Can Help With Climate Change. So How Do We Get Along?

Roughly 196 million tons of fish were harvested in 2020, according to the Food and Agriculture Organization of the United Nations. The organization also notes that the number of overfished stocks worldwide has tripled in the last century.  All of this overfishing has led to the decline of entire species, like Atlantic cod.  

Enter the Monterey Bay Aquarium's Seafood Watch. It and other free guides give consumers an overview of the world of fish and seafood, helping people to figure out the most sustainable fish available to them. With the help of Life Kit's Clare Marie Schneider, we figure out how to make informed decisions about what we eating – whether that's at a restaurant or the local supermarket.

Sustainable Seafood Is All Around You — If You Know Where To Look

When the dinosaurs walked the Earth, massive marine reptiles swam. Among them, a species of Ichthyosaur that measured over 80 feet long. Today, we look into how a chance discovery by a father-daughter duo of fossil hunters furthered paleontologist's understanding of the "giant fish lizard of the Severn." Currently, it is the largest marine reptile known to scientists.
