The rapid development of mariculture in China in recent decades has satisfied people's demand of seafood, and has made a great contribution to economic development. However, mariculture has also caused some negative impacts on the eco-environment. By statistically analyzing national data(as well as data for four main provinces) regarding the mariculture area and cultivation species in China since reform and opening up, the historical evolution of mariculture during the past 40 years was analyzed, the driving factors related to policy, market and technology innovation were discussed, and the potential impacts of mariculture on the coastal eco-environment were also illustrated. The statistical results indicated that the maricultural area increased radically during the past 40 years, from 1979(116.47 × 10~3 ha) to 2012(2205.65 × 10~3 ha), with an increase of nearly 20-fold. Shandong Province represented the fastest-growing region, with an increase of 31-fold. Moreover, the cultivated species had gradually become diversified. Initially, shellfish and algae were major species, and then it developed to various species including fish, and currently shellfish and crustaceans were the major species. The development of mariculture was driven by government policies, market economy and technology innovation. Rapid development of mariculture also caused significantly adverse impacts on the eco-environment of the coastal regions. For example, the sea reclamation for mariculture decreased the area and function of coastal wetlands and the contaminants originating from mariculture destroyed the coastal aquatic environment. Fortunately, the implementation of ‘13 th Five-Year Fisheries Planning' is expected to help both improve the seafood quality and reduce the contamination in coastal aquatic environment. This current study will provide reference for management and structure adjustment of mariculture in the future.

Plastic bags, though commonly used for packaging of goods, are highly durable and nonbiodegradable. Plastic bag litter serves as a negative environmental externality detrimental to animal health and natural beauty of the environment. In an effort to curtail the excessive use of plastic bags in Botswana, the government introduced a plastic levy targeted at consumers at retail points. This study uses primary data collected from 367 respondents randomly selected from six geospatially and purposively selected shopping malls to determine the consumers' willingness to pay(WTP) for continued plastic bag usage and their willingness to accept(WTA)to shift to eco-friendly alternatives. The results of the study revealed that open dumping and burning of plastic litter are more common in Maun than in Gaborone. It also showed that there is a significant relationship between the level of education and WTP. Further, there is a significant variation in income and education in respect to environmental awareness. The government should improve its efforts of sensitizing the public about the improper disposal of plastic bags.

Situated in the hinterland of the Qinghai Xizang Plateau, the eco environment of the source regions of the Changjiang (Yangtze) River and the Huanghe(Yellow) River are getting worse in recent years and has attracted increasing attention of researchers around the world. This paper discusses several major problems concerning the eco environment of the source regions. The authors hold that the two eco environment extents of the source region of the Changjiang River should be demarcated with the confluence of the Deng’ailongqu River to Zhidoi as its boundary, or 1.15×10 4 km 2 larger than the hydrological source area; while that of the Huanghe River should be delimited with Medotangumaxia in Darlag County as its limit, or 1.84×10 4 km 2 larger than the hydrological source area. The eco environment of the source regions with vegetation, soil, wetland, lake and river as the main elements, has always been affected by climatic changes, freeze thaw processes (including frozen soil freeze thaw processes and glacial snow cover freeze thaw processes), rodent damage and human activities. From an evaluation angle of fragile ecosystem, a study index system is established and several important issues for future research are suggested.

The construction industry is facing a big challenge in reducing the burden it is putting on the environment. There is an urgent need to develop and use eco-efficient construction materials with proper functional performance, a low carbon footprint and a less adverse impact on the environment. Nanotechnology is a new and very promising technology that helps fulfil the need for more environmentally friendly construction materials.
