Looking at the Discussion Group home page and noted the 4 gca periods defined as:
1. Pre-1899 "Natural Challenges"
2. 1900-1937 includes "The Golden Age"
3. 1949-1985 "The Dark Ages"
4. Present "Shaping Options, penal, to subtle sustainability"
Shouldn't the last 30 years be better defined than just "Present?" Does sustainability concept mark the current present state of the art gca?
Perhaps a New Golden Age?
