"The machine invades the landscape with destruction and transformation; it grows factories and whole manufacturing cities overnight, cities grotesquely hideous, where human misery is glaringly revealed; cities which, like Manchester, represent an entire stage of technology and which have become synonymous with hopeless dreariness. Technology darkens the air with smoke, poisons the water, destroys the plants and animals. It brings about a state in which nature has to be "preserved" from rationalized thinking, in which large tracts of land have to be set apart, fenced off, and placed under a taboo, like museum pieces. What all museum-like institutions make evident is that preservation is needed. The extension of protected areas, therefore, is an indication that destructive processes are at work."
