In his policy address yesterday, Chief Executive Donald Tsang Yam-kuen proposed introducing voluntary canteens in schools, in a move aimed at reducing disposable lunch boxes. Addressing lawmakers at the Legislative Council, Tsang said schools should be encouraged to do away with disposable lunch boxes and provide canteens for students. New schools could be built with canteens, he said, while existing schools could be retrofitted through an environment and conservation fund grant. He also suggested making it easier for mainland students to study in Hong Kong. 'We will explore the possibility of allowing mainland senior secondary students to study in Hong Kong,' he said, adding they could be offered short-term courses by degree-awarding schools or placement in non-public schools. In an effort to boost the moral fibre of young people, Tsang also said a 'happy family campaign' will be launched by the Family Council to encourage families to be more happy, kind, supportive, appreciative, and responsible. 'Many social problems, including juvenile drug abuse, prostitution and the neglect of elderly people and children, can be traced back to the family. Better family relationships mean fewer social problems,' he said. He added the Commission of Youth will also be hosting more arts, cultural, sports and recreation programmes. 'Parents should maintain good communication with their children, understand their interests, abilities and needs and develop their strengths in different areas. Moreover, parents should have reasonable expectations of their children,' he said. Acknowledging that secondary school students were still coming to grips with the new school structure, Tsang said young people not interested in formal education should explore cultural and creative industries, which are part of his six-pillar strategy for development. On the drug front, Tsang said a pilot drug-testing scheme in Tai Po would go ahead by year-end, while hair testing would be looked into. He said mentoring would be provided for drug users and for at-risk youngsters, while rehabilitation venues would be increased. Tsang also pledged further co-operation with the mainland on tackling cross-border drug abuse. Entitled 'Breaking New Ground Together', Tsang's fifth policy address maintained a cautiously optimistic tone, with a focus on youth, developing key industries and looking towards a continued recovery for Hong Kong in the years ahead.
