Richard, I had another thought. Mostly, the people who are advocating for better policies about the environment are nice, gentle people.
Nobody really pays them much mind. Especially since most of the solutions involve loss of money to the perps.
There is a crusty old saying "You have to fight fire with fire". In my view this applies to a lot of things, including dealing with the complete disregard for the environment leading to disaster for millions.
They HAVE to do something really big, to get that message across.
Okay, so maybe I tend to be a reactionary, but I have seen that nicey nice tactics simply do not work. Look at Gretta. they like to get their picture with her and they pat her on the head and tell her she is a good girl, but behind closed doors, they do sweet FA.
