Around 1,000 activists from local environmental protection groups lined up to form a giant 'CO2'at the Chiang Kai-shek Memorial Hall to mark Earth Day Sunday. Taiwan Environmental Information Center (TEIC) sponsored the activities in line with events held in New York, London, Sydney, Barcelona, Tokyo and Beijing. TEIC Chairman Chen Chien-chih said Taiwan first celebrated the international Earth Day 20 years ago at the same venue. Attendees from both the private sector and government agencies took part in a run to show their commitment to protecting the earth. Activities were also held in other parts of Taiwan, including a jogging event in Changhua County and other green activities in Nantou County and offshore Penghu County. Hu Ya-mei, chairwoman of the Homemaker's Union and Foundation, urged the government to fully implement carbon-reduction measures instead of only paying lip service to the issue.
