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.
From a scientific perspective there is some indication that a nuclear war could deplete the earth's ozone layer or, less likely, could bring on a new Ice Age - but there is no suggestion that either the created order or mankind would be destroyed in the process.
The park lies directly downwind from a slew of coal plants. Virtually all of the major contaminants in the local air and water are direct results of coal emissions. Coal produces ozone, which kills trees. Coal produces sulfates, which kill fish. No other park in the country has more ozone or sulfates than Shenandoah National Park.
What's happening to our world? Imagine the year 2000 and our ozone layer has vanished... Our planet has a fever and she is burning up - what will you do?
The way I see it is that love can put an end to this bureaucracy people go through in their relationships. But it can't blind you to the fact that maybe there are bombs, there are problems and the ozone layer is depleting.
Sometimes the media gives us the impression that we are terminal patients, because of problems of global warmth or the ozone layer. And the people, they don't understand that they can could change this situation for the better if they could act locally in a city.
