Each time you throw something as garbage‚ think of where it will finally end up. Whether

the adjacent cities such as Wujiang‚ Suzhou and Wuzhong. Lake East Taihu is a typical macrophytic lake‚ the richness and diversity of hydrophyte vegetated in Lake East Taihu are the highest in Taihu area‚ helping with the low occurrence of eutrophication[2]. As the development of economic and population increasing in the lake basin‚ Lake Taihu has suffered increasingly from serious pollution. Diversity of the aquatic macrophyte has been decresing from 75 species in total in 1980s to 55 species[3]
