Earth Day Number 48

Walt Kelly's famous Pogo poster done for the first Earth Day back in 1970.

I went off to Colorado State to work on my Masters in 1972 and was shocked by the terrible air quality and noxious brown cloud. Back then the only city with worse air pollution than Denver was LA. Over the years much progress has been made due to a number of changes that were driven by air quality regulations that were put into place along the Front Range - as per the two images shown here - 1970s vs this morning.

Let's hope that the common sense of the majority will prevail during this trying time and that our air quality will not be allowed to deteriorate back toward what it was in the last century.
