According to Senator Nelson, the moniker "Earth Day" was "an obvious and logical name" suggested by "a number of people" in the fall of 1969, including, he writes, both "a friend of mine who had been in the field of public relations" and "a New York advertising executive," Julian Koenig, who had been on Nelson's organizing committee in 1969, has said that the idea came to him by the coincidence of his birthday with the day selected, April 22; "Earth Day" rhyming with "birthday," the connection seemed natural. Other names circulated during preparations—Nelson himself continued to call it the National Environment Teach-In, but press coverage of the event was "practically unanimous" in its use of "Earth Day," so the name stuck.

 

Our Earth

The Earth is ours to enjoy
For every little girl
We must never ever abuse
Our sweet Earth that's ours to use.

The Earth is ours to enjoy
For every little girl and boy.
But we must always be aware.
That all its beauty we must share
With all the children yet to come,
Who want to laugh and play and run
Around the trees and in the fields.

So we must keep our planet free
From messy trash and debris
With air that's clean and fresh and clear
For all to breathe from year to year.
We must never ever abuse
Our sweet Earth that's ours to use.
