The new airport, connected by a bridge or tunnel to the city, would be only 12 miles from the Loop. But environmentalists talked of problems. They worried that the huge dike could dis rupt lake currents that now help to disperse pollutants. Jet-fuel spills from the pipeline or tankers could play havoc with aquatic life. Rock for the giant rampart might be mined from the lake bed, and that, too, could have major environmental consequences. Resistance to the plan has been heavy; it seems unlikely, now, that the airport will be built. Still, the controversy points up a battle that will be fought in coming years. Land seekers will continue to cast speculative looks offshore at all that potential "real estate." Increasingly, though, they will find environ mentalists barring their way.
