LOS ANGELES, May 9 (Xinhua) -- Drinking alcohol may raise the likelihood among teenagers to spend more time on computers, a new study suggests.The study, conducted by researchers at Weill Cornell Medical College, was based on a survey of 264 teenagers, aged 13 to 17.Results showed that compared with teens who did not report drinking, those who drank alcohol in the last month used a computer more hours per week for non-school-related activities, including the use of social networking sites.Drinking was also linked to more frequent social networking and listening to and downloading music, according to the study published Monday in the on-line edition of the journal Addictive Behaviors.However, there was no demonstrated link between alcohol use and computer use for school work, neither there was strong link between video games and drinking or on-line shopping and drinking."While the specific factors linking teenage drinking and computer use are not yet established, it seems likely that adolescents are experimenting with drinking and activities on the Internet," said Dr. Epstein, assistant professor of public health at the college."In turn, exposure to on-line material such as alcohol advertising or alcohol-using peers on social networking sites could reinforce teens' drinking."Children are being exposed to computers and the Internet at younger ages. For this reason it's important that parents are actively involved in monitoring their children's computer usage, as well as alcohol use."Teenagers typically first experiment with alcohol at age 12 or 13, according to the study.Family risk factors include lax parental supervision and poor communication, family conflicts, inconsistent or harsh discipline and a family history of alcohol or drug abuse."According to a national study conducted by the Pew Internet and American Life Project, more than half of parents of teenagers had filters installed on the computers their child uses to block content parents find objectionable, yet many parents do not use any form of parental monitoring, particularly for older teens," Epstein said.

MEXICO CITY, May 18 (Xinhua) -- The Mexican government signed an agreement with the non-governmental group TRAFFIC on Tuesday to exchange information about illegal seizures of flora and fauna species in Mexico.The agreement with the wildlife trade monitoring network also called for the Mexican government to provide information on the routes used to transport such organic materials.The agreement was signed on the sideline of the 16th meeting of the Trilateral Committee for Wildlife and Ecosystem Conservation Management in the city of Oaxaca, south Mexico. Representatives of Canada, the United States and Mexico also attended the meeting.Among the list of 20,000 animals, vegetation and insects that TRAFFIC considers to be threatened by illegal trafficking worldwide, 2,500 of the organisms have their origins in Mexico. This amounts to 12 percent of the species most subject to buying, selling and transporting in the black market and threatens the survival of various ecosystems.The Mexican species that are listed among the most threatened by illegal trafficking are the cactus, orchids, reptiles, maguey plants, ferns, amphibians and fish.
