Whatever happened to acid rain?

Josh and Chuck dive into the surprisingly fascinating world of acid rain, exploring how this 1980s environmental boogeyman actually works and what happened to it. They break down the science behind how sulfur dioxide and nitrogen oxides turn regular precipitation into something with the acidity of orange juice or coffee, and trace its journey from industrial smokestacks to damaged ecosystems. The hosts also celebrate one of environmentalism's biggest success stories, revealing how cap-and-trade programs dramatically reduced acid rain levels since the 1990s, proving that comprehensive action can actually solve large-scale environmental problems.
