When I was a kid, we never heard of smog, ozone depletion, acid rain, green house gasses.
We're looking at Earth science, observing our planet. Also space science, looking at the ozone in the atmosphere around our Earth. Also looking at life science. And on a human level, using ourselves as test subjects.
So I'm going to go on and work on preserving the ozone layer, encouraging everyone to recycle.
Since I was growing up in New Zealand where there's a hole in the ozone layer above us, we get so much sun damage to our skin, and the thing we can do to look after ourselves is use sunscreen during the day, but making sure your skin is well hydrated while you sleep.
Despite Arizona's remarkable growth in recent years, we have met the current federal health standards for ozone pollution and the Environmental Protection Agency recently approved our dust control plan.
