In the heart of Berlin’s Tempelhof-Schöneberg district sits a hulking, crumbling concrete cylinder—an abandoned relic of a Nazi plan to rebuild the city as a grand imperial capital. But this eerie structure isn’t just a forgotten engineering experiment; it’s a lasting monument to one of the Third Reich’s most colossal architectural failures.

Last week, we delved into story of how the Tennessee Valley Authority, which started out as a public institution, ended up acting like a private for-profit company, and the lawsuit that attempted to finally bring the TVA to its heel. Today, Montana Public Radio’s podcast The Wide Open tells the story of a different lawsuit against the TVA that had even bigger consequences. In the 1970s, the fight to save a tiny fish called the snail darter turned the Endangered Species Act from a minor bit of federal law into the most powerful and controversial piece of environmental legislation of the past 50 years.

We've all got problems. Sometimes your problem is a massive roadblock in your life, or maybe it's this little thing that quietly annoys you that you've learned to grudgingly put up with.
