If you care so much about imagined problems of dumping sludge in rivers, file a lawsuit or get someone with property downstream to do so and the courts will grant injunctive relief and all without the Marxist claptrap. The theory is that a PROPERTY OWNER has the right to enjoy undisturbed by the acts or negligence of others, having a clean unpolluted river flowing by is an amenity and property right of abutting landowners. We call this theory CAPITALISM or ECONOMIC FREEDOM. Envirowhackos should try it sometime. Unlike Marxism, it works!
Ok, so you don't see a moral problem with it. Fine, that's all I was asking. No need to rave on.
