I'm glad Tucson's ozone issue is being covered. Resolution Copper is at Oak Flat, not Rosemont.

Ozone is also dangerous for athletes, little children and anyone who is running or exercising.

Ozone is highly reactive. Among other things ozone fades dyes and damages plastics.

When exposed to bright sunlight, chemicals in car exhaust react to form ozone. That's one more reason tax breaks on EVs are a good thing.
