...places was already a slim margin of safety. Making the problem even worse is the loss of what Florida International University coastal expert Stephen Leatherman calls "living landforms," which would otherwise buffer that rise. Consider the wetlands that are an integral part of all river deltas, he says. Plants trap sediment from floodwaters flowing downriver, and the more they trap, the higher these wetlands grow. The problem is, people don't much like floods, so they build levees, which keep sediments from washing out of the rivers. They also don't much like wetlands, so they drain them...
...many contaminants have been markedly reduced in the Great Lakes (Superior is the cleanest), toxic chemicals like PCB remain a problem. Researchers plan to devote 16 dives to studying the nepheloid, a cloudy, particle-laden 6-in. layer of water just above the lake floor that seems to trap, and then rerelease, pollutants. "We had thought that bottom sediments were sort of permanent sinks for contaminants attached to particles," explains Steven Eisenreich, a professor of environmental engineering at the University of Minnesota. "Now we're finding out that under certain conditions these particles get recycled...
...years ago, using an ordinary modem and telephone, a young software saboteur penetrated the system at Manhattan's Memorial Sloan-Kettering Cancer Center with another kind of subversive programming, called a "trap door." The program collected users' passwords as they logged on. No matter how often legitimate users changed their sign-on codes, the hacker was able to gain unauthorized access to the hospital's records by summoning the intervening trapdoor and reading off the newly accumulated list of passwords. The culprit was later apprehended. He pleaded guilty and faced a maximum penalty of six months in jail...

Though the story evades the trap of complete triteness by eventually introducing a mysterious and deadly disease plaguing the community, oft-tread cliches weigh down the story’s first half...
Still, the play avoids the trap of caricature; Posner is genuinely excited about cancer and poetry, while Kelekian and Bearing share a moment complaining about the ineptitude of their respective students...
