Pope Benedict has warned young people about the dangers they face, not only in the physical environment, but online as well.

Speaking at Youth Day celebrations in Sydney, the pontiff said young people need to address challenges brought about by the erosion of the social environment.
These included the "exaltation of violence and sexual degradation, often presented through television and the Internet as entertainment".
He said people who had suffered from violence and sexual degradation would battle to understand them presented merely as entertainment.
