Greenhouse gas emissions.

We talk about that a lot on shortwave.

And it's a useful comparison because that existential issue is also human caused and could be human solved, so to speak.

So in comparison to climate change that we're all struggling with now, why do you think the ozone issue was dealt with so swiftly?

Giving up CFCs was a lot easier than giving up like oil and gas.

How does that make you feel as a researcher, that humanity, scientists working with policymakers, working with many stakeholders were able to do this?

How do you feel about that?

I hope I do.

You're listening to Shortwave from NPR.

Hey everyone, Emily Kwong here and welcome back to Nature Quest, our monthly segment that brings you a question from a fellow short waver who's paying attention to the environment and how our choices shape the world.

The stories Alessandra covered at the time were unfolding in other countries, in Thailand and in Canada.

But over time, she watched these climate narratives get closer to where she's from, Puerto Rico, Flint, Michigan, and eventually to her home state of California.

And more recently, Alessandra has had other reasons to be thinking about the future.
