One Planet, Three Crises

We are facing a triple planetary crisis. Climate change, biodiversity loss, and pollution aren’t separate problems – they’re interconnected threats that are unravelling our world.

This week, we’re exploring how these three crises collide through the lens of three seemingly different stories: frogs fighting for survival against chytrid fungus, sea ice melting in response to a warming planet, and air pollution suffocating ecosystems and human health alike.

Nina Ross and Dylan Scott make their research and radio debuts as undergraduate students from Australia and New Zealand. Over the summer, they worked in labs at The University of Melbourne as Amgen Scholars, and now they share what they’ve been up to.

We’ll explore the science behind each crisis, discover how they amplify each other, and ask: what can we actually do about it? Because frogs can’t hop away from these problems. Sea ice won’t freeze our solutions in place. And we can’t just blow off air pollution.
