Let us not, however, flatter ourselves overmuch on account of our human victories over nature. For each such victory nature takes its revenge on us. Each victory, it is true, in the first place brings about the results we expected, but in the second and third places it has quite different, unforeseen effects which only too often cancel the first. The people who, in Mesopotamia, Greece, Asia Minor and elsewhere, destroyed the forests to obtain cultivable land, never dreamed that by removing along with the forests the collecting centres and reservoirs of moisture they were laying the basis for the present forlorn state of those countries.
If you understand that the prairies surrounding Houston, the wetlands to the south of New Orleans and the brush that grew across the coastline around greater New York were closely related to the forests of the earliest class societies that Engels refers to, you will realize that “each victory” will bring us closer to the ultimate defeat of civilization itself. Just consider the words that follow those above:
When the Italians of the Alps used up the pine forests on the southern slopes, so carefully cherished on the northern slopes, they had no inkling that by doing so they were cutting at the roots of the dairy industry in their region; they had still less inkling that they were thereby depriving their mountain springs of water for the greater part of the year, and making it possible for them to pour still more furious torrents on the plains during the rainy seasons.
Furious torrents. Are there any words better matched to the pictures of Houston seen on television every night?
