Over the past four decades, numerous professionals in the field of environmental education (EE) have attempted to take stock of conditions within and outside of EE. In turn, many used the results of their analyses to describe challenges to and opportunities for EE. Many of these challenges and opportunities continue to ring true today, although the purpose of this article is not to explore those, but to explore several contemporary challenges and opportunities. The first challenge posed is to continue to expand and make use of the range of professional development opportunities within the field, such as is apparent in several of NAAEE's sets of Guidelines and related initiatives, particularly as the field continues to grow in numbers and in different directions. A second challenge pertains to the need for increased attention to sustainability in developed and developing nations' contexts, the rapid growth of “Education for Sustainability” (ESD) since UNCED, and the need to maintain clarity over the complex and dynamic relationships between EE and ESD with respect to sustainable development needs. A third challenge pertains to climate change as the most recent “environmental crisis” and set of problems we face, as evidence continues to mount. However, climate change represents a different kind of challenge, and underscores the challenge of preparing citizens to participate in problem-solving and in envisioning desirable futures through EE. In addressing these challenges and opportunities, we must continue to seek out and affirm the best of what is traditional and innovative, as well as effective and adaptive, within the field. 相似文献

水是生命的根基,也是人类社会一切物质活动的基础.在不同自然地域、不同经济生产、不同社会形态和不同民族文化以及不同时空环境中,水资源利用方式和水文化价值是不尽相同的.蒙古族传统游牧文化中水是神圣的资源,人、畜和草的命根.牧民在长期的游牧经济社会实践中形成了独特的水资源节约文化与环境保护知识.在草原地区进行水资源开发和现代经济建设时,必须要借鉴蒙古族独有的传统水资源保护文化和本土游牧生态知识,从而创建新世纪草原人地和谐共生模式,营造富有人文内涵的可持续发展局面. 相似文献

初中地理新课程与环境教育的相关性分析 总被引:1,自引:0,他引:1
HAN Mei 《课程.教材.教法》2008,28(2)
我国基础教育中的环境教育主要是以学科渗透的形式开展的,地理学科的性质和特点决定了它是渗透环境教育的主要载体。初中地理新课程从课程基本理念的引领、课程目标的相关、课程内容的支持、课程实施的落实等角度全方位体现了它与环境的密切关联,为初中地理新课程更有效地渗透环境教育提供了依据和保障。 相似文献

中国环境保护的难点与破解之道 总被引:1,自引:0,他引:1
周建 《北京师范大学学报(社会科学版)》2007,(4):138-142
中国环境保护事业飞速发展,在经济高速增长的同时,环境质量恶化的趋势得以减缓。但由于治理的速度仍赶不上污染的速度,环境形势依然严峻。做好新形势下的环保工作,必须加快环境与经济的融合,加快实现三个转变:一是从重经济增长轻环境保护转变为保护环境与经济增长并重;二是从环境保护滞后于经济发展转变为环境保护和经济发展同步;三是从主要用行政办法保护环境转变为综合运用法律、经济、技术和必要的行政办法解决环境问题。必须在国家战略层面将环境与经济有机结合起来,将环境保护的要求渗透到产业政策、货币政策、价格政策、财税政策和贸易政策之中,以环境友好的政策确保发展战略的顺利实施;将环境保护的领域由以生产为主,拓展到消费、分配、流通的各个环节,形成覆盖再生产全过程的环境管理体系;坚持从经济全球化的战略高度驾驭环境保护。 相似文献

Several studies have found a relationship between college students’ academic majors and their environmental attitudes and behaviors. Results from this study of incoming first-year students at a medium-sized public university suggest that students majoring in different programs of study were likely to have different environmental attitudes and behaviors. There were also differences in the proportions of women, political liberals, and financially secure students in each of the different majors. When controlling for the effects of gender, political ideology, and financial security, incoming business majors scored lower on two of the four measures of environmentalism than incoming students in the other majors. The findings in this study suggest that incoming students choose majors that are consistent with their worldviews. 相似文献

Two field studies form the basis of this article. The major purposes of Study 1 were to examine significant life experiences affecting the cultivation of environmental activists in eastern Taiwan, and to reconstruct the life paths followed by those active people who engaged in effective environmental action. 40 usable autobiographical memories were collected and content‐analysed to derive 17 significant life experiences. Based on the 17 accounts, a quantitative questionnaire of 24 items on significant life experiences variables was developed for Study 2. Four hundred and thirty valid questionnaires were analysed. Eighty two respondents with a high level of environmental action were determined to be environmental activists, and 153 with a low level of environmental action were determined to be people apathetic towards environmental protection. It was found that the significant life experiences identified in Study 1 could effectively distinguish environmentally committed people from those apathetic to environmental protection. Study 2 also found that 54.6% of the variances in environmental actions could be explained by the significant life experiences. 相似文献

目前,我国环境信息公开制度还相当落后,实践中的环境信息公开基本上是以政府为义务主体的主动公开(政府环境信息主动公开制度),以政府为义务主体的依申请公开制度(政府环境信息依申请公开制度)和以企业为义务主体的环境信息公开制度(企业环境信息公开制度)基本处于空白状态。随着环境问题的日趋严重,现有的政府环境信息主动公开制度暴露出越来越多的缺陷与不足,需要完善。本文指出了我国政府环境主动信息公开制度的不足,在此基础上,提出了一些完善建议。 相似文献
