Reply #45: It's a way to unify an idea/ideal, in the same way "Green" unifies an idea/ideal

I'm hearing green used in everything these days. It was the main trope in a librarian conference I went to a few weeks ago. It peppers the advertising one sees on television. It is used to indicate areas of conservation of resources. I saw that bicycle lanes are being painted green in NYC (and perhaps other big cities).

The color green and the word has been latched onto by modern society to unify folks toward the notion of saving the planet. It's really the same process that the flag was used for--especially in times of crisis such as the American Revolution, World War Two, or the Cold War.
