St Catherine's School for Girls' 'earth day' was packed with fun and also plenty of ideas on how to protect the environment. The girls put their books aside to take part in the day's activities, which included videos, bingo, role-play and group discussion on subjects ranging from ecosystems to land reclamation. School principal Sun Pong Tak-ling told Young Post that the event was aimed at boosting students' awareness of environmental problems. 'It's a good occasion for them to think more about the issues that they or the next generation may come across in future,' she said. Ms Sun was pleased that her school was recognised as the pioneer in this field. 'Both teachers and students have shown a good example,' she said. Many students helped by planting trees and selling fruit. They also tried to eliminate wastefulness and use more recycled materials. Sixth-former Joan Ng Wai-sze, chairperson of the Green Society, was proud of her colleagues' efforts. 'We can breath fresh air and see green spots on our campus. How wonderful,' she said. 'We combine interactive and interesting approaches to convey to lower-form students environmental messages. 'We encourage them to take steps to solve the problems.' Wai-sze said bringing home environmental ideas through fun days and other channels was more effective than compulsory lessons on the topic. 'You can do simple things like using the paper on both sides and fully utilising resources,' she said. 'Even eating at the canteen and not picking up food outside helps.' Seventh-former Tsang Yuk-yan said enthusiasm over environmental protection should be a continual process - not just for special days. She joined environmental group Friends of the Earth last year and decided to organise more activities after her A-Level examinations. 'We should join our hands together to bring the environmental messages to all walks of life,' Yuk-yan said. said. Chinese teacher Lau Lai-foon said students had a basic knowledge of the subject. Geography teacher Charles Liu Kwok-hung said that if students had a concrete idea about methods of environmental protection it could help alleviate problems. He said parents should play a crucial role in educating their children about protecting the environment. Green issues will be raised through the school's parent-teacher association.
