Manytheoriesconcerningthecausesofjuvenil
Many theories concerning the causes of juvenile delinquency (青少年犯罪) focus either on the individual or on society as the major contributing influence. Theories{{U}} (56) {{/U}}on the individual suggest that children engage in criminal behavior{{U}} (57) {{/U}}they were not sufficiently penalized for previous misdeeds or that they have learned criminal behavior through{{U}} (58) {{/U}}with others. Theories focusing on the role of society suggest that children commit crimes in response to their failure to rise above their socioeconomic status{{U}} (59) {{/U}}as a rejection of middle-class values. Most theories of juvenile delinquency have focused on children from disadvantaged families, {{U}} (60) {{/U}}the fact that children from wealthy homes also commit crimes.

The wandering ship was a dramatic symbol for a problem plaguing our age. In 1987, the ship, loaded with thousands of tons of New York garbage, spent weeks wandering from one port to another in search of a dump before finally returning home, mission unaccomplisheD、 New York, like other communities throughout the world is running out of space to put its trash.As throwaway societies, the US and other industrialized countries expect their garbage to be picked up by trucks that magically transported the refuse to some out-of-sight incinerator (焚化炉) or dump.But in the developing counties ofAsia,Africa and LatinAmerica, thousands of tons of trash collected daily are thrown into open dumps, where it feeds huge populations of rats that swarm through poor neighborhoods. "The world is literally swimming in garbage," says a scientist. "Communities worldwide are being forced to confront the problem." Green Peace spokesmanBryanBence adds, "The crisis in garbage stems in part from the fact that we’ve ignored long-term disposal problem in favor of cheap quick fixes." The garbage glut (过剩) has inspired many communities in the U.S., Japan and WesternEurope to start recycling programs. Once considered a curious counter culture activity recycling has moved firmly into the mainstream. Recycling involves separating usable products from trash, processing them so they can be substituted for more expensive raw materials and returning them to the marketplace as parts of new products. Many countries now have mandatory recycling programs, and others plan to follow the trend soon. Most notably, Japan has stood out as a model and leader of the waste management trend, recycling an estimated 65 percent of its waste. "That’s what we should do, to the garbage crisis", saysDavidAntonioli, a staff member with the New York Public Interest ResearchCorp. "The earth is not a dump!" |
