My daughter was born on Earth Day.
Earth day was born in 1970 at a teach-in.
Since then the Earth's environment has, unfortunately, been more and more abused by humanity even though we must have a healthy Earth to have a healthy humanity.
But in some ways we have come a long ways.
Even the NY Times in those days warned of the growing "hysteria" of the idea of global warming.
Almost everyone is "hysterical" about it now.
It can even be discussed in the context of economy and the survival of the human species on the earth.
