The ecology symbol was designed by cartoonist Ron Cobb in 1969 and was placed in the public domain so that it soon took off and became and iconic symbol of the 1970s, seen on buttons, T-shirts and posters. The ecology symbol, together with the raised fist, was a symbol of solidarity of the new ecology movement and a call to action to save the environment. The 1970s saw the first era of environmental awareness in the United States that resulted in the birth of the ecology movement, Earth Day, recycling, and the concept of being “green”.
