It must be sad to be an old environmental warrior: to reminisce about the days of barricades, placards, chants, feathers, drums and, well, copious amounts of hair. Clearly Clive Hamilton has been in a reminiscent mood. Perhaps he’s been fretfully stroking his shiny cranium while remembering the good ole Franklin Dam protests and what they achieved. Perhaps he nibbled on one of those special cookies that were so popular in those days.

How else could he come to the conclusion that mainstream environmentalism has failed because of "the professionalisation of environmental activism over the past two decades?"
