Another technological approach would not prevent bombings, but it could help identify those who commit them. Explosives can be chemically "tagged" so that telltale traces can be used to determine their origin after a blast. If producer nations could agree on a tagging system for military explosives, it would increase the chance that future terrorists might be tracked down and brought to justice...
...nuclear reactors work by splitting large atoms into smaller pieces, thus releasing heat. The challenge is to keep the core of nuclear fuel from overheating and melting into an uncontrollable mass that can breach containment walls and release radioactivity. One way to prevent a meltdown is to make sure the fuel is always surrounded with circulating coolant -- ordinary water in most commercial reactors. To guard against mechanical failures that could interrupt the transfer of heat, most reactors employ multiple backup systems, a strategy known as "defense in depth...
...would be packed inside tiny heat-resistant ceramic spheres and cooled by inert helium gas. Then the whole apparatus would be buried belowground. Lawrence Lidsky, an M.I.T. professor of nuclear engineering, calls this an "inherently safe" approach: it relies on the laws of nature, rather than human intervention, to prevent a major accident...
...things are lost. For example, the real names of some people who were central to the case. Even though these names are matters of public record and appeared often in newspapers, McGinniss changes them to, as he says, "preserve privacy." A more probable reason for fictitious identifications is to prevent libel suits. Because the impact of true crime depends on melodrama, the scenes and dialogue are liberally re-created by the author. Some of the dialogue seems too good to be true -- unless it appeared in a George Higgins novel. To readers this may seem like New Journalism...
What can be done to prevent the world from wallowing in waste? Most important is to reduce trash at its source. At the consumer level, one option is to charge households a garbage-collection fee according to the amount of refuse they produce. Manufacturers too need more prodding. Higher fines, taxes and stricter enforcement might force offending industries to curb waste. Industry must also re-examine its production processes. Such an approach already has a successful track record. The Minnesota Mining and Manufacturing Co. has cut waste generation in half by using fewer toxic chemicals, separating out wastes that...
