This would eventually lead to the final solution. However, the problem solution scenario is not so simple. Naturally, consumers＇ behaviors are difficult to be predicted and they do not always necessarily follow the rational-mind purchasing criteria. When purchasing food, mostly they choose the product because of its taste, quality and price, and lastly maybe due to its environmental friendliness from one hand. From the other hand, the manufacturer＇s priority is for the quantity sold and profit rather than product＇s environmental safety. Recently, is it possible to change consumers＇ mind-set and make them behave and select products in environmentally friendly manner？ The author thinks it＇s possible and the key is the kind of trigger through heart-moving incentive. This paper focuses on the Acorn Point System Project, which incorporates carbon foot print and carbon offset scheme, and argues about methods that can be used effectively and efficiently to facilitate those environmentally unmotivated companies and consumers to adopt environmentally friendly mind-set and shift to more proactive ones. This paper has confirmed that the most effective factors to stimulate unmotivated consumers to better acquire environmentally friendly mind-set, which leads to proactive eco-mind products purchasers and activists, are： （1） non-environmental product benefits must be stressed even for the environmentally friendly products; （2） environment consideration project incubation involves various interest parties and mechanism of shared satisfaction as a team; （3） start with small scale community project, which enables participants to recognize their project contribution.展开更多

A three-year monitoring campaign from 2008 to 2010 was conducted to identify the controlling factors of algal blooms and effective preventive measures. The following results were obtained: 1) Layered and bidirectional currents, called intrusive density currents, dominate the tributary bays of the TGR year round; 2) continuously increasing water level can make the intruding density current shift from the middle to the surface, and surface intrusive water can reduce the surface water temperature and break the stable stratification of the tributary; 3) the appearing or fading away of algal blooms is closely associated with fluctuations in the TGR water level. Thus, the water level fluctuation patterns of different "tide-types" may prevent the occurrence of algal blooms in the spring and summer, and the "stair-type" tides may control autumn blooms during the impounding period. These methods were feasible and effective throughout the actual TGR's operation in 2009 2011. These patterns formed an eco-environmentally friendly operation (EEFO) to mitigate algal blooms. As an in situ treatment with easier operation and less negative impact and loss, compared with chemical and filter-feeding fish methods, the EEFO is currently considered as the most feasible remedial measure to remit the eco-environmental problems at the Three Gorges Dam (TGD).展开更多
