This study, from the perspective of environmental ethics, duly proposed the brand-new concept of 'appropriate garden of primitive ecology', proceeded from the orientation, form, value, theoretical basis, realistic significance, culture and consumption psychology of 'garden of primitive ecology', fully developed outstanding ecological wisdoms and morals in traditional Chinese garden culture, boosted garden designs to the environmental ethics level of eco-justice, to seek for the approach to 'garden of primitive ecology' with indigenous Chinese environmental ethic characteristics.展开更多

Furthermore, utilization of WCO will refrain waterways pollution and endanger ecosystem. In Malaysia, more than 50-tone of WCO from various sources was produced every day. This study evaluates combustion performance and exhaust emission characteristics of several WCOs with different sources. Modification on fuel properties has been done to improve the combustion and exhaust emission of using WCO as diesel fuel. Regular diesel fuel also has been used for comparison in the test. A 0.6 liter, single-cylinder, air-cooled direct injection diesel engine was used to perform this experiment. Experiment was done at variable engine loads at constant speed.展开更多

But now there are some difficulties in native trees’ utilization and popularization dueto few study on landscape plant. In order to seek an abnormal and artificial landscaping and to produce an effective resultas soon as possible, native and foreign plants can be properly used as an available resource by improving their technological level and emphasizing natural balance. Then Chinese classic culture and green economics can be combined with beautiful forestry by implementing urban sustainable development.展开更多

This would shift the terrain of social critique and emancipatory social struggles. The paper introduces the debate on ＂social-ecological transformation＂ which emerged as a radical part of a more comprehensive debate on ＂great＂ or ＂societal transformation＂ and high- lights its core issues： the issue of a necessary attractive mode of production and living for all, the role of pioneers of change and changing political and economic institutions, the acknowledgment of shifting social practices, the requirement for alternative imaginaries or ＂stories＂ of a good life as part of a contested process which is called ＂futuring.＂ As an example for alternative imaginaries, the current debate on ＂degrowth＂ is outlined and evaluated. The second part of the paper focuses more concretely on issues around the formation and existence of a global green-left. After mentioning a crucial problem for any global alternative--i.e., the structural feature of economic and geopolitical competition which historically divided the global Left and pulled it into compromises at national or regional scales--four requirements or characteristics of a global green-left are highlighted： to weaken and change capitalistically driven competition and competitiveness, to push a social-ecological transformation in democratic ways and not at the back ofordinary people （like conservative and liberal proposals for transformation tend to do）, to link more systematically green issues with labor issues and, finally, to transform the overall dispositive of political action from a ＂distributive＂ to a ＂transformative Left.＂ One dimension of such an enhancement, it is concluded, is a broader understanding of the ＂economy＂ itself by acknowledging the demands and achievements of a ＂care revolution＂ which will be crucial for an alternative mode of production and living.展开更多
