Int'l Seminar Marks Bio-diversity DayAn International Workshop on Bio-diversity and Management of Alien Invasive Species was held in Zhuhai, Guangdong Province, Tuesday, which is also International Bio-diversity Day.Experts and governmental officials from home and overseas, including those from the United States, Britain and New Zealand, discussed alien invasive species in China's ecological system at the workshop, such as harmful moths and weeds, the economic losses because of them and the way to prevent and control such an invasion and enhance China's legal construction for the purpose. As one of the countries with the most abundant bio-diversity resources in the world, China has taken great efforts to protect its natural resources and ecological systems. A series of laws and regulations have been enacted to protect bio-diversity in recent years. Nearly 1,300 natural reserves had been built by the end of 2000, amounting to 9.85 percent of the country's total area. Large numbers of zoos, wild animal breeding centers, botanic gardens and gene banks have jointly contributed to maintaining China's bio-diversity, sources said. |
