HONG Kong exhibited a collaborative spirit on green issues last week as over 150 exhibitors took part in a first of its kind environmental extravaganza at the Hong Kong Convention and Exhibition Centre. Organised by local green agency Friends of the Earth (FoE), the three-day Green World Expo 94, drew local and overseas organisations from both the government and private sectors, on the theme ''Turn Over A New Leaf Towards a Sustainable Environment''. Environmental innovations in all sectors, from utilities to entertainment, were demonstrated through the displays and the public was encouraged to contribute to a greener world. The event was opened with a call from FoE chairman and Legislative Councillor Christine Loh Kung-wai to help improve Hong Kong's fast deteriorating air and water quality. ''Our current political and economic development emphasises 'more is better'. Fewer things, however, don't necessarily mean a poorer quality of life.'' In response, officiating guest Secretary for Planning, Environment and Lands Tony Eason announced that the Government's recently established Environment and Conservation Fund would soon be open for applications from community groups for environmental projects. Mr Xie Zhenhua, head of China's National Environmental Protection Agency, said China saw the need to increase co-operation with Hong Kong in fighting environmental pollution. An overseas booth, United States-Asia Environmental Partnership, displayed straws and bags made of the patented EnviroPlastic that could decompose within weeks. Kodak organised its first collecting centre for film canisters which would be sent to China to be recycled into plastic beads before being finally turned into other plastic products. Major local universities offered an insight into their environmental education programmes. The Hong Kong University of Science and Technology initiated the territory's first masters of science degree in Environmental Engineering for the 1995-96 academic year. Hong Kong Polytechnic will see its first batch of graduates taking the Environmental Engineering degree next year. A few tertiary students were awarded by Chevalier Telepoint for their prize-winning drawings in the Telepoint Green Education Programme. The Expo also featured a 3-D movie corner, animations, art, a green food bazaar, and a robot talk show. that was broadcast live on RTHK.
