A graveyard of ships — in the desert.
This environmental disaster in the Soviet Union was caused more by that failed country’s centralized state-run command society than the technological society they were trying to create. Though technology in any kind of society can certainly do harm to the environment, when all decisions are controlled by a single entity — in this case the communist Soviet government — it is practically impossible to adapt and adjust when things start going wrong.
In a free democracy, however, you have many safety valves. No project is ever so big that it effects everything, and if things start to go wrong the chaos of freedom will allow people to choose differently, correcting the problem more quickly.
