Let us not forget: socialism wasn't just tyranny, it wasn't just poverty; it was an environmental disaster. And for those of you old enough to remember, I'm not just talking about the Trabant motorcar. The Eastern cities were ugly, crowded, and dimly lit, covered in soot and grime, broken roads and footpaths. I remember the air was blue with exhaust smoke. And from trains passing through towns and villages, I saw factories spewing industrial waste into the supposed blue Danube on its way to the more aptly named Black Sea.
