Collapse_ How Societies Choose to Fail or Succeed - Jared Diamond [20]
The announcement of the Stock Farm’s development plan came as a shock to some Bitterroot Valley long-timers, who predicted that no one would pay so much money for valley land, and that the lots would never sell. As it turned out, the long-timers were wrong. While rich out-of-staters had already been visiting and buying in the valley as individuals, the Stock Farm’s opening was a symbolic milestone because it involved so many very rich people buying Bitterroot land at once. Above all, the Stock Farm drove home how much more valuable the valley’s land had become for recreation than for its traditional uses of growing cows and apples.
Montana’s environmental problems today include almost all of the dozen types of problems that have undermined pre-industrial societies in the past, or that now threaten societies elsewhere in the world as well. Particularly conspicuous in Montana are problems of toxic wastes, forests, soils, water (and sometimes air), climate change, biodiversity losses, and introduced pests. Let’s begin with seemingly the most transparent problem, that of toxic wastes.
While concern is mounting in Montana about runoff of fertilizer, manure, septic tank contents, and herbicides, by far the biggest toxic waste issue is posed by residues from metal mining, some of it from the last century and some of it recent or ongoing. Metal mining—especially of copper, but also of lead, molybdenum, palladium, platinum, zinc, gold, and silver—stood as one of the traditional pillars of Montana’s economy. No one disagrees that mining is essential, somewhere and somehow: modern civilization and its chemical, construction, electric, and electronic industries run on metals. Instead, the question is where and how best to mine metal-bearing ores.
Unfortunately, the ore concentrate that is eventually carried away from a Montana mine in order to extract the metals represents only a fraction of the earth that must first be dug up. The remainder is waste rock and tailings still containing copper, arsenic, cadmium, and zinc, which are toxic to people (as well as to fish, wildlife, and our livestock) and hence are bad news when they get into groundwater, rivers, and soil. In addition, Montana ores are rich in iron sulfide, which yields sulfuric acid. In Montana there are about 20,000 abandoned mines, some of them recent but many of them a century or more old, that will be leaking acid and those toxic metals essentially
