The Club of Rome said that if we didn't freeze economic activity at 1975 levels, and let the government take control of all resources and all economic activity, then all sorts of terrible things would happen.

In fact, it is precisely because of economic growth that we were able to invent the technololgy that made things better.

These things gave Eastern Europe the worst pollution that any area of the world has ever had.
