Reflectionafterteaching________________________________________________________________________________________________________________________________________________________________________________________________________________________Ⅰ.国际知名环保组织介绍这些国际性的环保组织克服了重重困难,获得了世界范围内的响应和支持,依靠组织手段,将提倡的环保概念普及,并通过各种环保项目的实施,切实推动世界各地的环保进程。(1)世界环保组织(IUCN)全名为InternationalUnionforConservationofNatureandNaturalResources,缩写为IUCN,该组织历史悠久,1948年即在瑞士格兰德成立,是政府及非政府机构都能参与合作的少数几个国际组织之一。由全球81个国家、120个政府组织、超过800个非政府组织、10000个专家及科学家组成,该组织共有181个成员国,实际工作人员已超过8500名。6,组织每3年召开一次世界自然保护大会(WorldConservationCongress)。IUCN旨在影响、鼓励及协助全球各地的协会,保护自然的完整性与多样性,并确保在使用自然资源上的公平性,及生态上的可持续发展。(2)世界自然基金会(WWF)WWF是在全球享有盛誉的、最大的独立性非政府环境保护机构之一,在全世界拥有将近500万支持者和一个在90多个国家活跃着的网络。WWF的使命是遏止地球自然环境的恶化,创造人类与自然和谐相处的美好未来,保护世界生物多样性;确保可再生自然资源的可持续利用;推动降低污染和减少浪费性消费的行动。该组织的标志为大熊猫。(3)全球环境基金(GEF)GEF是关于生物多样性、气候变化、持久性有机污染物和土地荒漠化的国际公约的资金机制。GEF通过其业务规划,支持发展中国家和经济转型国家在生物多样性、气候变化、国家水域、臭氧层损耗、土地退化和持久性有机污染物的重点领域上开展活动,取得全球效益。自1991年启动以来,GEF已通过1000多个项目,向140多个发展中国家和经济转型国家提供了大约40亿美元赠款,并从各种渠道吸引了120亿美元的项目融资。2002年8月,32个捐资国保证,在随后4年内,向GEF提供近30亿美元,用于GEF活动。(4)国际绿色和平组织1971年,12名怀有共同梦想的人从加拿大温哥华起航,驶往安奇卡岛(Amchitka),去阻止美国在那里进行的核试验。他们在渔船上挂了一条横幅,上面写着“绿色和平”。尽管在中途遭到美国军方阻拦,他们的行动却触发了舆论和公众的声援。次年,美国放弃在安奇卡岛进行核试验。在此后的30多年里,绿色和平组织逐渐发展成为全球最有影响力的环保组织之一。该组织继承了创始人勇敢独立的精神,坚信以行动促成改变。同时,通过研究、教育和游说工作,推动政府、企业和公众共同寻求环境问题的解决方案。绿色和平组织在中国的环保项目包括气候与能源项目——致力于减缓由燃烧煤、石油和天然气等化石燃料造成的气候变化,还有致力于消除有毒污染物的污染防治项目,森林保护项目品等。(5)地球之友(FriendsofEarth)在香港地区创立的“地球之友”(FriendsoftheEarthInternational)是著名的环境非政府组织之一,还是反全球化运动的一支重要力量。与其他环境组织一样,“地球之友”近年来也改变了就环境问题谈环境的做法,转而将环境问题与社会问题及发展问题联系起来,既扩大了活动领域,也扩大了影响。自1983年成立以来,“地球之友”曾经走过一段艰辛的路。在香港的超级物质主义的大潮流下,“地球之友”仍然坚守使命,捍卫公众利益,维护环境公义,不屈不挠地推动环保,反对扩充发电厂、滥用杀虫剂、侵占郊野土地、关注过度消费、城市空气污染、水质污染、填海和环境管理失误等问题。Ⅱ.KidsF.A.C.E.(儿童环保组织“为了世界更清洁”)MelissaPoewas9yearsoldwhenshebeganacampaignforacleanerenvironmentbywritingalettertothethenPresidentBush.Throughherownefforts,herletterwasreproducedonover250donatedbillboardsacrossthecountry.TheresponsetoherrequestforhelpwassohugethatPoeestablishedKidsforACleanerEnvironment(KidsF.A.C.E.)in1989.Therearenow300000membersofKidsF.A.C.E.worldwideandistheworld'slargestyouthenvironmentalorganization.PoehasalsoaskedtheNationalParkServicetocarryouta“Children'sForest”projectineverynationalpark.In1992,shewasinvitedasoneofonlysixchildrenintheworldtospeakattheEarthSummitinBrazilaspartoftheVoicesoftheFutureProgram.In1993,shewasgivenaCaringAwardforhereffortsbytheCaringInstitute.Sincetheorganizationstarted,KidsF.A.C.E.membershavedistributedandplantedover16,milliontrees!Ongoingtree-plantingprojectsincludeKid'sYards—thecreationofbackyardwildlifehabitats(栖息地)andnowKidsF.A.C.E.isinvolvedintheexcitingEarthOdyssey,whichisagreatwaytostarthelping.“Startingtheclubturnedouttobeawaytohelppeoplegetinvolvedwiththeenvironment.Clubmembersstarteddoingthingslikerecycling,pickinguplitterandplantingtreesaswellasinvitingotherkidstojointheirclub.”“Wetrytotellkidsthatit'snotOKtobelazy,”sheexplains.“Youneedtostartbeingaresponsible,environmentallyfriendlypersonnow,rightaway,beforeyoubecomearesource-suckingadult.”6
