“Fresh water lake in China has been very fragile ecosystem, there are 14,000 square kilometers of lake eutrophication, or has the edge in eutrophication, algal bloom events have occurred,” yesterday’s meeting, the Chinese Academy of Engineering, China Environmental Science Research Institute researcher Liu Hongliang concern expressed that, in 2007, survey of 43 lakes, 27 lakes in the eutrophic state of Lake Taihu, Chaohu and Dianchi lakes, such as 12 in the severe eutrophication.

Experts criticized the bad habits people
“Lake management is not the interception in the difficulty, but in the quality of the people, particularly littering the greatest harm to the lake.” Yesterday, the International Lake Environment Committee of the Scientific Committee Vice WalterRast an interview that the life bad habits into lake pollution “stumbling block.”

WalterRast said pollution was mainly the two lakes, one is business, residential sewage pipes, a very simple way to deal with, as long as the government to build sewage interception pipeline and sewage treatment plants can; another source of pollution is a lot of rubbish into the the lake, some garbage could be easily decomposed, on the lake’s pollution greatly. In fact, these people are not interested in rubbish thrown into the lake, but throw in the street, the rain into the lake after it rains.

Present, some countries and regions are trying to separate storm sewers, sewage treatment plant re-entry, but the investment is huge. The most direct and effective solution is to make the public aware of its importance, try not to throw rubbish at random.
