The greenie's hysteria about blocking all dam construction illustrates a common element of almost all the socialist/greenie policies.
They planned on using the natural, and generally well documented climate cycles, along with restrictions on normal and necessary water/power supply infrastruture expansion, to create and magnify a fear campaign in order to stampede the public into support for their radical, leftist, social engineering policies.
Most people who have lived more that a few decades are quite familiar with these natural weather cycles and recognise the fundamental necessity to build water and power supply infrastructure to cover for the extremes of the cycle in accordance with population and industrial growth.
The radical socialist/greenies political agenda was to block these necessary infrastructure expansions, while encouraging an open-borders policy to place further strain on this now purposely insufficient infrastructure.
Water and power supply are choke points of control for all communities and these were prime targets for the greenies.
As we know the greenies have been quite successful at this destructive anti-human campaign.
The greenies did not plan on elements of the public waking up to their deception in such a short time and being less that cooperative.
The greenie strategy required a wholesale "collapse" of communities due to purposely resticted water and power infrastructure prior to the turn of the climate cycle.
The greenies, with a corrupt and complicit media, raised the public hysteria and fear through the lows of the climate cycle, to such an extreme that the greenies, claiming to have an answer, were even considered as suitable by a growing portion of the electorate to be appointed as our leaders and decion makers.
The greenies were not that far away from at least a partial success in their plans.
