earthday symbolIn 1969, artist, writer and political cartoonist Ron Cobb created an international symbol for ecology. The symbol was formed by taking the letters “e” and “o”, taken from the words “environment” and “organism”, and putting them in superposition, thereby forming a shape reminiscent of the Greek letter Θ (Theta). He published it in the Los Angeles Free Press on October 25, 1969, and placed it in the public domain.
