A group that has become active in my area is the waterkeeper alliance.
They come across as relatively rational till you start looking deeper and realize that their real problem is all us filthy humans. The only way to save the planet is global governance and the elimination of private property rights.
They don’t like logging, dams, private wells, farming, mining, construction, fossil fuels, fishing hunting..........
Waterkeepers = Another numbnuts Kennedy telling people how to live.
