re: We don’t have to turn off all the lights
As usual you take a practical approach to saving energy and use great examples of common sense. The trouble is, not everybody thinks as cleverly a syou so the worldwide dramatic gesture could open the eyes of the normally ignorant people and have a glimmering affect on them and there waste of energy.
I guess I’m lucky to be living in a suburban neighborhood that has no streetlights and crime is unheard off. In the downtown cities there really is no way to scrap lighting but facing them down instead of towards the sky works for me.
