What They Predicted:
People at the turn of the century fully expected that mankind would have utterly devastated the natural world by now. They envisioned an Earth with no wildlife whatsoever remaining, save for what we specifically bred and protected. And they had a word to describe this barren, lifeless wasteland:
Apparently the people in the past were pretty sure we would've finally gotten our shit together and won the war against Mother Nature that we all forgot we were waging. They saw a future where there were literally "no Mosquitoes nor Flies. Insect screens will be unnecessary. Boards of health will have destroyed all mosquito haunts and breeding-grounds, drained all stagnant pools, filled in all swamp-lands, and chemically treated all still-water streams. The extermination of the horse and its stable will reduce the house-fly." They not only thought we would have intentionally burned, paved over, and chemically sterilized all the world's marshland, but look at how they thought we'd reduce the house-fly problem: "The extermination of the horse." The horse. As in, the collective horse. The entire species.
