大学生环保论文2000字英文版高中版

保护地球，从我做起古往今来，地球妈妈用甘甜的乳汁哺育了无数代子孙。原来的她被小辈们装饰得楚楚动人。可是，现在人类为了自身的利益，将她折磨得天昏地暗。人类只有一个地球；而地球正面临着严峻的环境危机。“救救地球”已成为世界各国人民最强烈的呼声。我为周围环境的恶化而感到心痛，我想：作为未来接班人的青少年，如果不了解人类环境的构成和环境问题的严重性，无视有关环境保护的法律法规，不去增强环境保护意识，自觉履行保护环境的义务的话，我们的生命将毁在自己的手中，老天将对我们作出严厉的惩罚。为此我下定决心要从我做起爱护环境，保护我们这个赖以生存的家园，做一个保护环境的卫士。在刚过去的一年中，我积极参加学校开展的植树活动，带领我们初一(6)中队的班干部创立了“绿色天使”植绿护绿小组，鼓励队员们在校园里认养了一棵小树苗，利用课余时间给它梳妆打扮，为它长成参天大树打下了基础。在学校组织的“让地球充满生机”的签字活动中，我郑重地在上面签下自己的名字，并写下了自己对环保的决心和期望，对美好未来的憧憬。我积极参加学校在世界环境日举行的有奖征稿，认真查阅、收集各类资料，进行社会调查，撰写有关环境治理设想方面的文章，我经常去参加学校组织的环保讲座，观看环保方面的录相带，积极参预环保知识问答调查活动，认真填写每一项提问。我参与了“红领巾植绿护绿队”的网站建设，在上面发布大量的环保图片和环保知识，以及关于环保的各方面的法律知识，我国在环保方面发展动向、世界各国的环境保护情况；每个月我都利用网络、报纸，查找一些最新的不同的专题和板块“环保资讯”来告诉大家；还定期制作一些宣传板来宣传环保知识和生活中的环保常识。提高了大家的环保意识；号召同学们从不同的方面来关爱自己的家园，从身边的小事做起，为周围的环境奉献自己的一份力量!我积极动员身边的人一起来依法保护和建设人类共有的同样也是仅有的家园，为促进经济和社会的可持续发展，为人类的文明做出贡献。我还和同学们共同发起“养一盆花，认养一棵树、爱惜每一片绿地，让我们周围充满绿色”和“小用塑料袋不使用泡沫饭盒和一次性筷子，让我们远离白色污染”的倡议。让我们放下方便袋，拿起菜篮子，让我们共同走向美好的绿色的明天，走向辉煌、灿烂的未来! 据我收集到的一份报告说：“环境问题是由于人类不合理地开发和利用自然源所造成的。触目惊心的环境问题主要有大气污染、水质污染、噪声污染、食品污染、不适当开发利用自然资源这五大类。”一个个铁一样的事实告诉我们，它们像恶魔般无情地吞噬着人类的生命。它威胁着生态平衡，危害着人体健康，制约着经济和社会的可持续发展，它让人类陷入了困境。为此我作出宣告：“只要我们——人类有时刻不忘保护环境的意识，有依法治理环境的意识，地球村将成为美好的乐园”。未来的天空一定是碧蓝的，水是清澈的，绿树成荫鲜花遍地，人类可以尽情享受大自然赋予我们的幸福。 “真正检验我们对环境的贡献不是言辞，而是行动。

低碳经济与低碳生活论文摘要：阐述了低碳经济与低碳生活的概念和两者之间的关系。“低碳经济”是国际社会应对人类大量消耗化石能源、大量排放二氧化碳引起全球气候灾害性变化而提出的新概念。它不仅意味着制造业要加快淘汰高能耗、高污染的落后生产能力，而且意味着要引导公众反思那些浪费能源、增排污染的不良嗜好。从而充分发掘消费和生活领域节能减排的巨大潜力。指出“低碳经济”仅有先进技术的支撑是不够的。必须依托于“低碳乍活”才能实现减排的目的。而“低碳生活”是一种简单、简约、俭朴和町持续的生活方式，要实现“低碳生活”，宣传引导和制度保障是缺一不可的。论文关键词：环境科学；低碳经济；低碳生活；可持续消费低碳经济的概念及形成背景2008年6月5日“世界环境日”的主题定为：“转变传统观念，推行低碳经济”。“低碳经济”，是近年来国际社会应对人类大量消耗化石能源、大量排放二氧化碳引起全球气候灾害性变化而提出的新概念。它的核心是在市场机制基础上，通过制度框架和政策措施的制定及创新。形成明确、稳定和长期的引导和鼓励，推动提高能效技术、节约能源技术、可再生能源技术和温室气体减排技术的开发及运用，并促进整个社会经济朝向高能效、低能耗和低碳排放的模式转变。进入21世纪，全球油气资源不断趋紧，保障能源安全压力逐渐增大。全球环境容量瓶颈凸现。同时气候变化问题也成为有史以来人类面临的最大的“市场失灵”问题。在此背景下。英国率先提出“低碳经济”的概念，并于2003年颁布了《能源白皮书（英国能源的未来——创建低碳经济）》。现在，欧美发达国家大力推进以高能效、低排放为核心的“低碳革命”，着力发展“低碳技术”。并对产业、能源、技术、贸易等政策进行了重大调整。以抢占先机和产业制高点。日本作为推动“低碳经济”的急先锋。每年投入巨资致力于发展“低碳技术”：美国参议院2007年提出了《低碳经济法案》，美国政府制定了低碳技术开发计划。这一切对我国而言，已形成压力和挑战。我国现在正处于工业化、城市化、现代化加快推进的阶段。基础设施建设规模庞大。能源需求快速增长。“高碳经济”特征突出的现实，成为我国可持续发展的一大制约。怎样走出一条既确保经济社会快速发展。又不重复西方发达国家以牺牲环境为代价谋求发展的老路，同时又不盲目让西方国家牵着鼻子走，是我们必须面对的课题。从技术角度看低碳经济保障能源安全和应对气候变化无疑是“低碳经济”要实现的最重要的两个目标。英国所倡导的“低碳经济”。是通过制定和实施工业生产、建筑和交通等领域的产品和服务的能效标准及相关政策措施，通过一系列制度框架和激励机制促进能源形式、能源来源、运输渠道的多元化。尤其是对替代能源和可再生能源等清洁能源的开发利用，实现低能源消耗和低碳排放的目标。最终实现以更少的能源消耗和温室气体排放支持经济社会可持续发展的目的。1新能源二氧化碳排放量的不确定性从技术创新的角度看，“低碳经济”的理想形态是充分发展太阳能光伏发电、风力发电、氢能以及生物质能技术。一般把太阳能光伏发电、风力发电、氢能等称为新能源或替代能源，生物质能是替代能源中的可再生能源。风力发电虽然近年来发展很快。技术有一定程度的突破，但目前它的成本也还是高于煤电、水电。此外，由于风力发电在发电过程中不排放二氧化碳。而火力发电过程要排出大量二氧化碳。因此人们认为风电不排放二氧化碳。这实际上是一种误解！与火力发电相比，风力发电在发电过程中虽然不排放或很少排放二氧化碳。但在制造风力发电设备及其维修、维护过程中却是一定要排放二氧化碳的。我们不能光比较发电过程的二氧化碳排放量，应当比较火力发电和风力发电发出单位电量全程的二氧化碳排放量。由此可见，认为风力发电、电动汽车不污染环境，不排放二氧化碳的观念并不是很科学的。现阶段太阳能发电的成本是煤电、水电的5～10倍。作为二次能源的氢能，目前离商业化目标还很远。技术还很不成熟。应认识到。一方面由于技术不过关，目前新能源开发的成本高：另一方面。由于新能源二氧化碳排放量的不确定性。在没有进行全程二氧化碳排放量的计算之前，不能轻言新能源是低二氧化碳排放的能源。2推行粮食生物质能燃料的后果生物能源是可再生能源。发展生物质能技术，看似“一石两鸟”。既解决化石能源的替代和紧缺问题，又改善环境。但从目前实施的结果看，它带来的问题似乎比解决的问题还要多。美国发展生物质能的新政策出台后，美国的粮农们纷纷扩大玉米的种植面积。或将种植其他作物的土地也改种为玉米。据统计，2007年美国玉米种植面积和产量均创下1944年以来的最高纪录，产出的玉米中多达1／5被用来生产乙醇汽油。如此旺盛的需求当然也造成了玉米价格的上扬。仅2007年一年。美国国内的玉米价格就上涨了50％。此外，由于被玉米挤占了种植空间。大豆的供应量减少。价格也开始上涨。因此布什的新能源政策招致了不少人的批评。联合国粮农组织专家琼·齐格勒警告说。一些国家将粮食转化为燃油的做法是一种“反人类罪”。这种做法将加剧全球范围内的粮食短缺。抬高粮食价格，让更多贫困人口难以承受。利用粮食作物转换成生物燃料的政策，对于日益严峻的全球粮食短缺问题无疑是雪上加霜，必将给世界造成更大规模的饥荒。在中国，2007年猪肉和食用油价格的一路飙升。一个非常重要的原因就是饲料价格的上涨，而且粮食价格飞涨波及的不仅仅是中国。美国的一项能源政策对世界范围内的食品价格产生这么大的影响。可谓是美国生物燃料政策的实施，客观上已经形成了全球8亿有车族与20亿最贫困人口之间针对粮食展开的较量。而具有讽刺意味的是，开发生物质能的计划并未带来化石能源紧张问题的丝毫缓解，倒是使新旧问题相互交织，给人类带来了更多的困扰。然而这并不意味着技术创新和新能源的发展对于“低碳经济”不重要。而是在推行“低碳经济”的同时要倡导“低碳生活”，或者说，“低碳生活”应当是“低碳经济”的重要组成部分。低碳经济应依托于低碳生活“低碳经济”的重要含义之一，不仅意味着制造业要加快淘汰高能耗、高污染的落后生产能力，而且意味着要引导公众反思那些浪费能源、增排污染的不良嗜好。从而充分发掘消费和生活领域节能减排的巨大潜力。在市场经济的体制和观念下，“低碳经济”高能效、低能耗技术状态下的生产仍然是追逐最大利润。因此大量的生产就不可避免，所生产的产品最终一定要想办法卖出去，而且卖得越多越好。然而大量生产必然会产生大量污染、大量排碳。单位能耗虽然降低了。但能耗总量因大量生产而大大增加。二氧化碳的排放量不会减少多少或许还会增加。举例来说，通过几十年的努力，小汽车行驶100km的耗油量下降了约50％，但由于小汽车的总量增加了几十倍。显然污染和二氧化碳排放量也增加了许多倍。因此说。“低碳经济”仅有先进技术的支撑是不够的。必须依托于“低碳生活”才能实现真正的节能减排目的。1“低碳生活”是可持续的生活方式“低碳生活”是一种简单、简约和俭朴的生活方式。人们的衣食住行都与二氧化碳的排放量乃至于气候变化有关。比如一张A4纸的能源含量接近于1kW·h电，由此就可算出它的二氧化碳排放量。如果绝大多数人的生活能够采取低排碳的适度消费的方式。那么“低碳经济”的实现是有可能的。什么样的生活方式就有什么样的经济。“低碳生活”不只包括制造业、建筑业中许多节能技术改进的细节，还包括人们日常生活习惯中许多节能的细节。对于目前世界上第一人口大国的中国，每个人生活中浪费的能源和二氧化碳排放量看似相对微小。而一旦以众多人口乘数计算。就是巨大的数量。如今在许多发达国家。很多人已经自觉第接受了支撑低碳经济的低碳生活方式，他们愿意放弃享受，从生活的点点滴滴做起。从关掉暖气到放弃驾车上班。今天欧洲人越来越喜欢乘坐火车出行。一个主要原因是乘高速列车带来的人均碳排放只有飞机的1／10。简约生活，也正在成为更多中国人家庭生活的准则。一些收入早已进入中产阶级的市民，也会穿着旧衣服去早市买便宜青菜。骑自行车出行。使用最老款的手机。煮鸡蛋早关一分钟煤气、用洗衣服的水冲厕所、随手关灯、打印用双面纸等习惯早已深入到那些最有教养的阶层中去，从而带来心灵的宁静。然而，能够自觉接受可持续消费价值观指导，做到适度消费的人是不多的。追求高消费依然是社会生活的主旋律。绝大部分情况下低碳经济还只是人们心目中的一个概念。低碳生活也只是处在令人尴尬的纸上谈兵阶段。在实际生活中，以大量消耗能源、大量排放温室气体为代价的“面子消费”、“奢侈消费”的比例太高。一方面在努力实现“低碳经济”，一方面又不停地挥霍。这些都是消费主义文化使然。消费主义文化总是不断刺激你去换最新款的手机、电视、衣服、鞋子：轰炸般的商业广告煽动着公众一浪高过一浪的消费欲望，把人变成商业利润的工具。不少刚参加工作不久的年轻人，用一个月的收入买一款新式手机或一个名牌皮包眼睛都不眨一眨。中国现在每年平均淘汰近7000多万部手机，产生着大量的电子垃圾。不少年轻女性家里堆满了各种款式的鞋子和皮包。但还是要去买更新的款式。在提倡“低碳生活”的今天，“能挣会花”的口号不再象征着现代化理念。而象征着一种浪费资源的野蛮消费方式。大量生产、大量消费、大量废弃的生活方式，正走向人类文明的反面，严重制约了可持续发展战略的实施。不但污染了生态环境，而且污染了人们的心灵。正是这种无限膨胀的消费欲望造成了世界能源、资源的紧缺。2“低碳生活”要有制度保障2008年6月13日。湖北省首次公示部分省直机关办公建筑能源审计结果，包括省建设厅、交通厅、发改委在内的20个省直机关办公楼，每年每平方米的平均耗电量为80kW·h，是普通民宅的3-4倍。而在这之前，国务院办公厅以及湖北省政府都发布了节能降耗建设节约型机关的通知，并且还作出了一些具体的要求。政府部门的规定不能取得明显成效的根本原因。在于公务人员的节能纯粹是个人道德、认识的体现，即使有一些具体的要求，也只是柔性的，没有一种刚性的制度约束来催逼人们节约能源。如果政府对节能的要求有制度性的保证，那么公务人员一旦不节能，就会受到组织、经济、行政等方面的惩戒，那样将会极大地推进节能措施在政府层面的有效落实。2008年6月16日《解放日报》报道，上海市将办公节能措施具体化，如制定了“夏季着清凉装上班。除外事礼仪需要外不穿两装不系领带”、“办公楼四楼以下不乘用电梯”、“公务出行拼车、乘用公交车”等规定，正在将办公节能措施具体化，并率先在公务人员中推行。这在大方向上应该看作是走向了制度化。如果这些制度再辅之以惩戒措施，将会更现实化，也将便于操作。全民的环境与可持续发展宣传教育已开展多年，公众的环保意识有了一定程度的提高，除了道德层面的教育引导外，还必须有制度的约束。2008年6月1日之前，许多人怀疑“限塑令”的可操作性，但颁布后，还是得到了广大市民的理解，并且取得了实效。总之，“低碳生活”的广泛实施，将扼制“高碳经济”的蔓延，促进“低碳经济”发展。要实现“低碳经济”这一目标。“低碳生活”的宣传引导和制度保障是缺一不可的。

人或动物的生存与植物有密切的关系，你相信吗？如果不想信，让我们一起瞧瞧下面的文章，带你走如环保世界！不久前，我们家搬入了现在的新房子。刚搬完家，叔叔阿姨们就送来了好几盆花和几株树。门口、客厅里、房间里和阳台上都摆上了盆景。我笑眯眯的爸爸说：“我们家都有成植物园了，摆那么多的植物干吗？”爸爸笑着说：“植物能制造气氛，净化空气，人和动物谁都离不开它们，离开了它们都有不能生存。”人或动物离开植物后不能生存？为什么人或动物离开植物后不能生存？我将信将疑，时不时还发出一些疑问的声音。决定做几个小实验来证明这个问题。星期天，我从车库里抓来两只老鼠。这两只可怜的小老鼠即将成为我的实验品。它们不停地挣扎着，圆溜溜的一次性薄膜桌布小眼睛瞪着我。我把第一只小巧玲珑老鼠放在一个大鱼缸里，用把玻璃瓶封得严严实实的，生怕瓶里的空气与外界的空气相通。我仔细地观察着，只见小老鼠沿缸着壁，绕着缸底快速地向前窜。咦，小老鼠不是活得好好的吗？难道爸爸说的不是真的？可是，没过几分钟，只见小老鼠绕圈的速度越来越慢，直到停滞不前，奄奄一息的样子。顿时，我把一次性薄膜桌布轻轻拿开，捉出第一保小老鼠，放进第二只小老鼠，又搬入了四盆枝繁叶茂的植物。然后轻轻盖上一次性薄膜桌布。我不停地拍打鱼缸，只见小老鼠惊慌地乱窜。过了好久也没要咽气的样子。这个实验证明了植物可以输送动物所需要的氧气，为了进一步证明人类和动物对植物的依赖性。来到我们老家附近一个饲料加工厂。那儿的空气里到处弥漫着一股哝哝的灰尘味，熏得我直咳嗽，不停地，我感到十分难受。然后，我又跑向我们家屋后的一片竹林里，那是一极为空气新鲜的地方，我感觉格外清爽。在植物的孕育下，一股股清新而淡淡的竹子的清香飘进个个人的心田……这个实验证明植物可以净化空气，使人呼吸顺畅。这两个实验证明，人类和动物的生存与植物有密切的关系。这其中到底有多大的科学道理呢？我为了追寻答案，来到图书馆去查阅了很多很多的科技书籍，还到百度上搜索了许久，终于总结出以下几点：一、人必须依靠植物提供氧气，只有植物才能制造氧气。如果说一个人几天不吃饭、几天不喝水且有一息尚存的话，几分钟就可能性命难保，氧气可是人生命活动的第一需要呀！一个成年人每天呼吸约2万多次，吸入氧气75千克，呼出二氧化碳9千克。二、动物与植物的呼吸，物质的燃烧，也都要消耗氧气，释放二氧化碳。这样一来，空气中的氧气不就一天天增加么？不！天地间之所以没有产生过这种危机，就是因为植物既是天然氧气“制造厂”，又是二氧化碳的“广阔市场”。有科学家做过统计，1公顷阔叶林，在生长季节每天能制造氧气750千克，吃掉二氧化碳1000千克。所以算起来，只要有10万平方米的林木，就可以供给一个人一身的氧气的需要量，并把呼出的二氧化碳吸收掉。因为有植物源源不断地补充氧气，空气中的氧气才能保持基本恒定。相反，如果没有植物，地球上的氧气只要500年左右的时间既可以用完。所以，人类和动物能够维持生命，活动时所需要的氧气，必须归功于绿色植物。植物与我们人类和动物的生命有着相当密切的关系。在此，我们成都玉林中学附属小学四年级四班何佳懋同学呼吁全社会的人们不要再砍伐植物，不要再让植物哭泣！让植物成为我们最好的朋友，好吗？

How to protect the environment?　　Nowadays， more and more people realize it`s necessary and important to protect the Also，there are some people who don`t pay attention to hygiene and they can`t stop littering the rubbish casually or spitting everywhere all the And in addition， there are a few factories often cutting down the trees， discharging chemicals and dirty water and so And it causes many problems like the Greenhouse EIf they do these day by day and our life will be harder and harder，so we have to stop To stop them we can put up commonweal advertisements and tell them the detriment of destroying the So we can start from now to make a beautiful

Protection of the EnvironmentOnce man did not have to think about the protection of his There were few people on the earth， and natural resources seemed to be Today things are The world has become too We are using up our natural resources，and polluting our environment with dangerous If we continue to do this， human life on earth will not We realize that if too many fish are taken from the sea， there will soon be none Yet，with modern fishing methods， more and more fish are We know that if too many trees are cut down， forests will Yet， we continue to use powerful machines to cut down more and more We see that if rivers are polluted with waste products， we will Yet， waste products are still put into We know that if the population continues to rise at the present rate， in a few years， there won’t be enough What can we do to solve these problems?If we eat more vegetables and less meat， there will be more food Land for crops feeds five times more people than land where animals are Our natural resources will last longer if we learn to recycie The world population will not rise so quickly if people use modern methods of birth Finally， if we educate people to think about the problems we shall have a better and cleaner planet in the 保护环境过去，人们不必担心保护环境的问题。因为那时地球上人口稀少，自然资源似乎取之不尽。如今，一切都改变了。世界变得拥挤异常。我们正在耗尽我们的自然资源，有毒化学制品的使用也正污染着环境。如果我们继续这样下去，地球上的生命将不复存在。我们都知道如果从海里捕捉太多的鱼，海里就不会再有鱼了。但是，现代化的捕鱼技术使得捕鱼量越来越大。我们都知道如果砍伐太多的树木，森林就会消失。但是，我们仍旧使用强大的机械砍伐越来越多的树木。我们都知道如果河水被废弃物污染的话，我们只有死路一条。但是废弃物仍然源源不断地进入河里我们知道，人口继续照现在这个速度增长的话，不出几年，就会发生食物短缺。我们该如何解决这些问题呢?如果我们多吃蔬菜，少吃肉类的话，我们就会有更多的食物。因为同样大小的土地如果种庄稼的话会比养殖动物多养活五倍多的人。如果我们学会再利用的话，自然资源就能持续更久。如果人们使用现代化的生育控制方法，世界人口就不会增长如此迅猛。最后，如果我们能够教育人们都意识到这些问题的话，未来我们就会有一个更好、更洁净的星球。

Since the first time having blown bubbles in my Open Water class， I've logged over 100 This love for diving has evolved into an intense passion towards protecting the ocean， and all of its I've chosen to put my love for the ocean into action， as an Actually， this passion extends out towards efforts that look to help all the planetary domains gain As such， I appreciate when others take the time educate me on those other realms for which I know less To be an environmentalist， one must choose the cause which resonates within ones sole， and run with One must be willing to educate people about the environment while being open to education from those people who support other Together we can help each other towards learning how to become a true "Environmentalist" We must all encourage positive collaboration and education as opposed to being against For example， sharks are being decimated to near extinction simply for their The fins are used to make Shark Fin soup， a delicacy popular particularly in Taiwan and S It would be easy to blame these communities for creating the However， in conversing with Asian environmentalists， they liken the culture around eating Shark Fin soup to the culture surrounding Americans eating turkey for Thanksgiving There are ongoing efforts to educate these people， by members of their own community， on just how dangerous this cultural practice is and the devastating impact this could have on their (our) world if all the sharks were to disappear as a Environmentalists everywhere are making a difference! Famous restaurants have taken endangered Swordfish off their menus， these same restaurants are buying wild-caught salmon (and boosting the economy of local fisheries in the process)， laundromats have started selling green detergent， this just to name a few of these enlightened This is how the "Environmentalist" can begin the Just find something you believe in and make a One by one， we can make our planet a cleaner place to live， steeped in healthy bio-diversity for generations to 3Giving 1% to Protect Our Environment Though most of the world's surface is covered by water， since the Earth is so large relative to human horizons， there doesn't appear to be a shortage of However， when one begins to think of land in terms of a human resource，， a producer of food， a provider of wood， an expanse for passage， one realizes that many portions are either too lacking in nutrients， too high in elevation， too prone to flooding， or too cold or ice-ridden for extensive Furthermore， habitable lands are becoming less abundant due to desertification (the expansion of deserts due to the misuse of land)， agricultural expansions and rising sea Since humans aren't the only species that need land， it isn't surprising that this resource is becoming limited for other forms of life In part as a result of this added stress on living things， we are also witnessing extinctions of grand proportions-at a rate of many thousands species per Since these losses are largely due to human actions， such as deforestation and non-native species introduction， many are beginning to pay attention to how we use and protect Recent ecological research has also recently provided a message of hope concerning the future well-being of life on this In the world today， scientists estimate that the Earth is losing at least 1 percent of species every ten years， and the percentage loss may be close to 5 Even if only the lower rate persists， the Earth will have lost near half of its biological diversity by Can this be possible? Many esteemed scientists think While the future appears bleak， several recent insights tell us that we have the potential to significantly reduce what amounts to a biotic holocaust， one not witnessed on Earth for over 60，000，000 While there are hopeful signs in the area of human activities (such as increased acreage of nature preserves and national parks)， the hope of which I speak of here stems from specific characteristics of the other forms of life which may enable us to mutually coexist in the long The Earth's organisms are wonderfully varied in size， shape， function， behavior， and genetic One only need to consider that there are ~ 15，000 species of butterflies and ~50，000 species of mushrooms worldwide to begin to fathom the immensity of variety that this planet Yet， as different as the species come， the bulk of living things are also similar in a couple of very important Most living things live in relatively small regions and do not travel far from where they or their parents were In fact， recent biological and ecological work has determined that most land species are very particular about where they As opposed to humans whose choice of home is largely driven by economic and political forces (mobility driven by availability of wealth or forced relocation)， flora and fauna find themselves in locations for which they are We now know that many species of insects and plants have a very restricted range in which they Very few organisms are ubiquitous like we It goes without saying that you aren't going to find a Great Blue Heron or a Grizzly visiting Antarctica or climbing M Everest; yet you might find the snow bear (recently discovered and previously known as the Abominable Snowman) doing the Recognizing that most living things are rather localized during their lifetimes has profound implications， both hopeful and On the one hand， it suggests that we can learn a lot about species by parking our scientific minds in specific On the other hand， it means that if we destroy even small areas of the globe we are likely causing great and even irreversible destruction to the species that are found We have also determined that there are specific locations on our planet where a disproportionate number of species For our species， Asia serves as the homeland for In fact more than 60 percent of humans lives on this largest of continents (which only makes up 24 percent of the land surface on the planet) With other life forms， geographic concentrations sometimes defy We only recently became aware that the vast majority of terrestrial (as distinguished from oceanic or riparian) species collectively live on just 1 percent of the Earth's land (If humans lived at a comparable concentration level， we'd all have to cluster together in an area roughly the size of Antarctica or twice that of A) This mind-blowing realization has prompted those that have been struggling to protect organisms a new way of thinking about such They have concluded that if we humans could somehow find a way to avoid disturbing just 1-2 percent of the land surface， nearly 70 percent of the world's terrestrial species might be able to Recently some conservationists have refocused their attention on these unique The regions of the globe that contain such a splendid array of biological diversity have been named "hot spots，" a name that communicates their critical In what has to be the most beautiful books I have seen， Hotspots represents the collective work of scientists Russ and Cristina Mittermeier and Norman Myers as well as photographer Patricio Robles G In this oversized volume， these four scholars have assembled more than three hundred vivid photographs of some of the world's endangered species and threatened These absolutely breath-taking images come from the what they refer to as "the 25 most critically important regions" in the These regions originally constituted almost 12 percent of the world's land surface but now， due to human pressure at many levels， only a little more than 1 percent remains What makes these locations， which are found on all continents except Antarctica， so "hot" is that they are home to hordes of the Earth's plants and animals and they face imminent danger from a variety of human The Hotshot authors and others strongly believe that the global community can do wonders if these areas move to the top of our priority But what will have to happen for these spots to be protected? There are no simple answers to this central Unfortunately， those of us in the United States who have the luxury of time to even ponder such questions， face many obvious First， nearly all of the hotspots are located outside of our territorial boundaries， exceptions being the forests of Oregon and California as well as portions of Southern Florida (namely the Keys and the Everglades) Key hotspots are found in New Zealand， Madagascar， and Indonesia as well as the continental parts of south-east A Obviously we cannot expect that we will be able to force other countries to enact and enforce laws that will greatly reduce biological Yet， while many other countries have ratified the Biodiversity Treaty that was drafted at the 1992 Rio Earth Summit， it has never reached the floors of the US Congress for a vote; Canada， Japan， and the European Union are among those to ratify By this inaction our nation apparently lacks the wherewithal to support global conservation efforts as a matter of However， given that the wealthy nations in concert with international banks promote unsustainable extraction of resources in the world's developing countries， it would appear that we have an obligation to do If our national policy makers are unwilling to commit themselves to the protection of global ecosystems and species， we still have ourselves to look to for sources of positive All of us have tremendous purchasing power， especially in comparison to the majority of the other human residents on this planet; Barry Bearak， a Pulitzer Prize-winner journalist who recently spoke at Knox College's convocation， referred to the residents of the United States as "filthy rich，" a conclusion he came to after spending a great deal of time in the poorer regions of the world， particularly Afghanistan and I What we buy makes a The environmental campaign to support shade coffee rather than sun coffee is just one of many attempts for the consumer to support sustainable practices in regions of great ecological According to the Northwest Shad Coffee Campaign， shade coffee agricultural allows for the extraction of a desired resource but at the same time allows between 3-8 times as many birds species to persist not to mention many more mid-size mammals as well as amphibians and Coffee is also a particularly important commodity in terms of the health of ecological systems because the countries that produce the bulk of it are precisely the same countries that are home to the majority of the world's species; the countries of Brazil， Bolivia， Indonesia， Vietnam collectively produce ~40 percent of the 17 billion pounds of coffee that are harvested each year (folks， that's more than 3 pounds per person!) Burdensome debts also force many developing countries to endlessly delay infrastructure Debt-for-nature swaps， an idea proposed by D Thomas Lovejoy of the World Wildlife Federation in the mid-1980s， have enabled poor countries to relieve foreign debt and international nongovernmental organizations (NGOs) to increase commitment to conservation programs both at the same In these swaps， NGOs pay off a poor country's debt to a bank or well-to-do country at greatly reduced costs in order to establish agreements for investment in national parks， for While not a cure-all， these efforts have begun the paradigm shift from unabated expansion and unhealthy extraction to one supportive of saving natural ecosystems and securing the health and welfare of all human Threats to these locations represent massive scale intrusions taken by societies found on every Unfortunately， there is so much that will be lost if these "special" places aren't quickly protected from future On the bright side though， so much of the world's genetic diversity lives in just a couple handfuls of "hotspots" that if these locations were saved hordes of species would be able to persist into the next The time is now to respond to this fairly recent observation and It is time for the world to begin to act like a civilized 21st Century It is incumbent upon us， those with time and wealth， to maintain the momentum that others have The masses of life forms are relying on us to make the best attempt at this daunting yet critical Hopefully our species will be sensible enough to leave at least 1 percent of land alone， so that other life forms may continue to Do we need all 100 percent? 写不下了，如果觉得不够，邮箱可否留一下，我继续补充
