To feed hungry furnaces, the land was stripped of trees. Sulphur fumes destroyed the undergrowth. Soon only a desert of red earth remainedand erosion left gullies deep and wide enough in some places to hide a two-story building. Now waste fumes are converted into sulphuric acid. Ducktown with itsgreen trees rises asanoasis (page 567).
