Does Earth Have Limits?: The Chemistry of Pollution, Episode 4

Pollution is only one way humans are altering our planet. There’s climate change, sea level rise, biodiversity loss, and much more. Earth system scientists, including biological oceanographer Katherine Richardson, developed the nine planetary boundaries, a framework to understand what Earth systems are critical for life, and what will happen if human-caused changes to our planet continue. Katherine unpacks these boundaries, revealing how chemistry sits at the heart of both the problems and solutions to the equilibrium of many of these critical systems. It’s a sobering yet hopeful look at humanity’s future on a finite planet. Transcripts and episode sources at acs.org/chainreaction
