Letters: We need to protect the Earth

Last week we traveled from Dallas to Fresno on American airlines.

I enjoy flying over the southwest. You can see the effects from millions of years of change on the surface of the High Desert. I noticed a volcano cone, and a bit west was a great wall. Looked like the Great Wall of China. It was north-south following the tectonic plates, breached by water. I could see the erosion scars as the water rushed through. Further west was another ridge that was the shoreline of a huge lake.

Last night on the news was a story of college kids going to D.C. to discuss politics in a face-to-face setting instead of on social media. Their most concern was climate change. They are alarmed and that’s good. We need to be concerned, but not alarmed.
