The record of people's manipulation of nature in the Florida Everglades is replete with examples of remedies that were never fully analyzed before they were applied -- remedies that inevitably turned out to be more disastrous than the troubles they were intended to cure. It was people's judgment, for example, that the rich muck of South Florida was going to waste under waste; so people drained off the water only to discover that muck, expod to the heat of the sun, oxidizes into thin air. In some agricultural districts now as much as 40 percent of the organic soils are gone. Some farmers will be ploughing limestone by the year 2000. But they won't be raising any crops. Similarly, drainage undertaken to increa food production in one area has inhibited productivity in another; in periods of drought, the long canals became arms of the a and salt water intruded on the land. In 1945, salinity in the soil killed off 18,000 acres of vegetables in southeast Dade country. Now increasing salinity in Florida Bay, caud by the decreasing outflow of fresh water from the Everglades, threatens the natural offshore nurry ground of the Tortugas shrimp and a '20 million annual commercial fishery.
