The Environmental Movement

This button depicts the ecology symbol, a small letter “e” inside the larger letter “O,” the letters standing for “environment” and “organism.” Cartoonist Ron Cobb invented the symbol in 1969. The ecology symbol appeared in a green U.S. flag for the first time in the April 21, 1970 issue of Look magazine.
