To enhance public awareness of the importance of 'greening' the environment, various community involvement projects and educational activities were organised in 2002. These included the Green Hong Kong Ambassadors Scheme, community planting days, Green Hong Kong Activities Subsidy Scheme, green camps, theme flower shows, horticultural courses and seminars. The Green School Subsidy Scheme was also organised to promote greening initiatives at schools and it attracted the participation of over 660 schools and kindergartens. In addition, nine schools took part in a pilot scheme in September in which students learned how to maintain plants in parks.
