A Texas pecan farmer spent years rethinking whether he needed so many chemicals to grow food. He cut back on things like weedkillers, but when it came to ditching insecticides, crop pests posed a challenge. That’s what brought him together with a famous bat scientist — who helped him build an insect-eating army of bats.

Astronomers need your help! And you don’t have to be an expert, because it’s as easy as stepping outside your home and taking a good look at a constellation like Orion. For 20 years, the citizen science project Globe At Night has helped advance our understanding of light pollution — as scientists figure out how fast stars are disappearing from our sky.

As we embark on our third year of Up From Dust, we discuss why we started an environmental podcast in the Midwest — and what we’ve learned along the way. In 2026, stay tuned for stories about farmers, astronomers, turtles, bats and more. We’ll overcome fears and rethink how we grow food and build our cities. And we’ll meet the people in the Heartland who tackle the challenge of climate change with determination and resolve. Thanks for coming along with us.

In one long-polluted Ozark river, the little fish darting through the water and the rare mussels hiding on the pebbly bottom tell a story worth celebrating. They’re signs that the Spring River is benefitting from environmental cleanups after a century of mining pollution. A professor and his students are uncovering the evidence of recovery. But there’s a twist: They’ve also found a new environmental challenge unfolding farther upstream.

Trevor Starks is on a mission. He wants to help the humble but powerful creatures that clean the waters of the Neosho River: freshwater mussels. For decades, their populations dwindled due to overharvesting, pollution and dam construction. To right the wrongs of the past, Trevor and his colleagues are releasing rare mussels by the hundreds. Now, the only thing left is to find out if it worked.

The Midwest has a reputation for vast fields of corn and soybeans that stretch to the horizon. But on some farms, strips of wildflowers and little bluestem now interrupt the crops, tiny glimpses of the prairie that once dominated the region. They’re an effort to hold back the fertilizer runoff that pollutes drinking water and then travels hundreds of miles downstream, where it fuels the Gulf of Mexico’s infamous Dead Zone.

Have you ever wondered how much life a tiny patch of land can hold? Nebraska scientist Chris Helzer photographed one square meter of prairie from every angle for two years, getting to know the creatures that call it home. By blending art and science, he hopes to open people's eyes to this underappreciated ecosystem on the Great Plains that’s shrinking more and more every year.

Microplastics are everywhere. They’re in the air we breathe, the clothes we wear, even the food we eat. Scientists are still trying to understand what these tiny particles are doing to the environment and our bodies. But an accidental discovery at the University of Michigan in 2019 – involving baby diapers and rubber tires – has broken ground on an idea for how to get them out of our water. (This episode comes to us from the podcast Points North at Interlochen Public Radio.)

This episode was produced by Michael Livingston, hosted by Dan Wanschura and edited by Morgan Springer, Ellie Katz, Ed Ronco, Peter Payette and Dan Wanschura.

For decades, the world’s longest prairie river was treated as a convenient dumping ground by cities and industries. Government regulation dramatically improved water quality here and around the country. Today the Kansas River is a place to scope out beavers and bald eagles. But decades-old garbage and other pollution still plague the river, so a motley crew of kayakers took it upon itself to dig out the trash.

We have inadvertently filled our world with poorly designed outdoor lighting. The price? We’re losing our starry skies, hurting our health, killing pollinators, wasting billions of dollars and releasing millions of tons of avoidable carbon dioxide. Now people in a Missouri college town and a state park are proving that picking the right bulbs and fixtures can curb light pollution and its harms.
