And if we see someone do the harm things to the environment, like spit on the ground or step on the grass, we can stop them from doing so. If there’s a factory which destroy the environment, it’s our right and incumbency to tell the relative department or the police about it.
All in all, although we are students we can still do a lot of things to protect our environment. So we should act from now on to make our contribution to the environment, for it’s our conjunct home.
今天,我们的环境也存在着一些问题.作为一名中学生,我们应该做些事情来改善我们的环境条件.
我认为首先是我们自己不应该破坏了环境,例如乱扔垃圾.我们还可以参加一些公益活动,种更多的树,因为它们能做很多帮助我们的环境.如果我们看到别人做的事情对环境的危害,就像吐唾沫在地面或步骤在草地上,我们可以阻止他们这样做.如果有一个工厂,破坏了环境,这是我们的权利和义务告诉相关部门或警察.
总之,虽然我们都是学生,我们还是可以做很多事情来保护我们的环境.所以我们应该从现在开始行动作出我们的贡献的环境,这是我们的相连的家.

Do not neglect the water pollution water is the source of life, and the water is not divided. Adult body accounts for about 65% of the water body weight. Human blood 80% water, the water consumption per capita per day for 2 ~ 3 liters. All human physiological activities, such as the body's temperature control, nutrition, conveying, waste discharge all need water to complete.

不可忽视的水污染水是生命的源泉,人和水是分不开的.成年人体内含水量约占体重的65％.人体血液中80％是水,每人每日的用水量为2～3升.人体一切生理活动,如体温调节、营养输送、废物排泄都需要水来完成.如果人体减少水份10％,便会引起疾病,减少20～22％就要死亡.生活中人们一天也离不开水.水对生命来说是必需的,然而,水也是疾病传播的重要媒介. 水污染对人体的危害是多方面的,当人体受到化学有毒物质污染后(如666),会引起人的急性或慢性中毒.如果汞、镉、砷、氰化物、农药、多氯联苯等侵入人体后,都可以引起人体中毒.污水中有害物质在土壤中积累并被植物吸收,加上不适当地使用化学农药,会使大量残留的有害物质散布到田间,继而污染粮食、蔬菜、烟叶等农副产品,引起疾病.另外,水污染还会引起水媒介的传染病,如人畜粪便等生物性污染,可以引起细菌性肠道传染病,如伤寒、痢疾、霍乱等.总之,水污染已成为人类自己的大敌,如果忽视了对水污染的防治,终有一日人将难以在地球上生存.保护水资源、防止病从口入,人人尽一份力,我国的水环境一定会好起来.

世界水资源的缺乏World Water Shortage
A new study warns that about thirty percent of the world's people may not have enough water by the year 2025.
一项新的研究结果提出警告：到2025年,世界上将有30%的人没有足够的水饮用.
A private American organization called Population Action International did the new study. It says more than three-hundred-thirty-five-million people lack enough water now. The people live in twenty-eight countries. Most of the countries are in Africa or the Middle East.
这项研究是由美国一家名叫“人口行动”的私立机构进行的.报告说现在世界上有三亿三千五百万人没有足够的水.这些人主要分布在非洲或中东的28个国家.
P-A-I researcher Robert Engelman says by the year 2025, about three-thousand-million people may lack water. At least 18 more countries are expected to have severe water problems. The demand for water keeps increasing. Yet the amount of water on Earth stays the same.
人口行动组织的研究人罗博特.安格曼说,到2025年大约三十亿人缺水.至少还有其他18个国家将可能面临同样严重的水短缺问题.人类对水的需求不断上升,但地球上水的还是保持不变.
Mr. Engelman says the population in countries that lack water is growing faster than in other parts of the world. He says population growth in these countries will continue to increase.
安格曼先生说,水短缺的国家的人口增长率要高于世界其他地区的人口增长率.他还说这些国家的人口出生率将持续增长.
The report says lack of water in the future may result in several problems. It may increase health problems. Lack of water often means drinking waters not safe. Mr. Engelman says there are problems all over the world because of diseases, such as cholera, which are carried in water. Lack of water may also result in more international conflict. Countries may have to compete for water in the future. Some countries now get sixty percent of their fresh water from other countries. This is true of Egypt, the Netherlands, Cambodia, Syria, Sudan, and Iraq. And the report says lack of water would affect the ability of developing to improve their economies. This is because new industries often need a large amount of water when they are beginning.
报告表明,在未来,水资源的缺乏可能会导致一些严重的后果.首先它可能会产生更多的健康问题.水资源的缺乏就意味着饮用水不再有保障.安格曼先生说,诸如霍乱等在水中传播的疾病会使世界出现许多问题.水缺乏也会引起更多的国际纷争.各国可能由于水而发动战争.现在有些国家,例如埃及,荷兰,柬埔寨,叙利亚,苏丹和伊拉克等,60%的纯净水是从国外进口的.报告认为水缺乏将影响发展国家发展经济的能力.这是因为新工业在开始阶段经常需要大量的水.
The Population Action International study gives several solutions to the water problem. One way, it says, is to find ways to use water for more than one purpose. Another way is to teach people to be careful not to waste water. A third way is to use less water of agriculture.
人口行动组织的研究报告为世界的水短缺问题提出了几个解决的办法.第一,找到多用途的用水方法.第二,教育人们不要浪费水资源.第三就是少用农业水.
The report also says long-term solutions to the water problem must include controls on population growth. It says countries cannot provide clean water unless they slow population growth by limiting the number of children people have.
报告同时表明,控制人口增长是长远解决水缺乏问题不可缺少的措施之一.它说除非各国能通过限制生育来降低人口的增长,否则它们不可能提供干净的水.
Global warming a bigger threat to poor全球变暖加剧贫穷 气候变化急待控制
Global warming, modelled on computer here, kills more people than terrorism
Global warming threatens to reverse human progress, and make unachievable all UN targets to reduce poverty(联合国所有减少贫穷的目标), according to some of the world's leading international and development groups.
In a report published today, Oxfam, Greenpeace, Christian Aid, Friends of the Earth, WWF(英国牛津救济委员会、“绿色和平”组织、基督徒互援会、“地球之友”组织、世界野生动物基金组织) and 15 other groups say rich governments must immediately address(致力于) climate change to avoid even "obscene levels(无法忍受的程度)" of worldwide poverty.
"Food production, water supplies, public health and people's livelihoods are already being damaged and undermined," the report says. "There is no either/or approach possible(想找一个‘非此即彼'的办法是不可能的). The world must meet its commitments to achieve poverty reduction and also tackle climate change. The two are inextricably linked(二者的联系是难解难分的)."
The report, which draws on UN predictions of the effects of climate change in poor countries over the next 50 years, says poor countries will experience more flooding, declining food production, more disease and the deterioration or extinction of entire ecosystems(整个生态系统的退化甚至消失) on which many of the world's poorest people depend.
"Climate change needs to be addressed now. The poor will bear the brunt of the impacts. The frontline experience of many of us working in international development indicates that communities are having to combat more extreme weather conditions."
Climate change will play havoc（大范围的破坏；浩劫） with agriculture and water supplies and will increase diseases. "By 2025 the proportion of the world's population living in countries of significant water stress will almost double, to 6 billion people. Tropical and sub-tropical areas will be hardest hit - those countries already suffering from food insecurity(食品短缺)".
Poor communities mostly do not need hi-tech solutions, but would most benefit from education, research and being shown how to farm better. The report says unchecked global warming(尚未得到抑制的全球变暖), more than wars or political upheaval(政变), will displace millions of people and destabilise many countries.

重视一颗树的命运
重视一棵树的命运,不知有多少人能够认同这个观点.
我们不妨先作个假设：如果设一个“森林法庭”,我们每个人都会成为被告.通过陈述实录,就可以作出明确的判断——比如,在成片的大面积林区发生山火,至少要达到“亩”的数量才能称为灾.即使像1987年大兴安岭森林大火那样的灾害,人们虽然给它定性为“特大”,但烧死了多少树,谁也数不清.在这里,树作为生命被“草菅”了.多数人以为原始森林,是祖先留下的,烧掉太可惜了,而发出的也只是感叹.
自然保护区或西部干旱地区,砍伐或毁烧了树木,是要以棵为单位来脏水、堆垃圾的废料场,油污的侵蚀,使一些树木在返青之前就葬送了自己的生命……
计算的,因为这些地方的树木太珍贵了.有山没树是很荒凉的,人们渴望有树.
在内蒙古赤峰地区,树是政府和老百姓的“眼睛”.最典型的事例是,砍掉一棵树也要惊动当地政府官员,山上一冒烟,不管烧没烧着树,市长都会出动.道理很简单,生活在沙窝子里,几十年几代人种树,在树的身上他们投入了太多的血汗,也收到了显而易见的成效.人们看重树,也依赖着树.“案情”已经相当明了：“家大业大”,手就会松一点,“小门小户” 就要精打细算,要是“贫困户”更不敢轻易动血本了.从以上的陈述,可以看出,树作为一个活的“生命”,生存的地位被以这样或那样的形式给剥夺了.而这些“犯罪”行为,恰恰是我们人类至今没有引起重视的一个“盲点”.
对生命的伤害,尤其是对无辜生命的伤害,每个人都应该感到愧疚,包括一棵树、一根草和一切微观世界的生命.但在生活中,人类的生存和发展,在需要和保护面临选择的时候,对待树的“生命”就出现了人为的不平等.大到引发火灾、乱 滥伐,小到随意践踏、不经意的伤害,这样的例子数不胜数.在树叶渐渐枯萎的悲凉中,一座座大楼破土动工了.在冬季树木休眠的季节,树的立足之地,也就成了倒

We may wish to make an assumption: if you set a "forest court", we everyone becomes the defendant. By stating memoir, can make clear judgment - for example, in the large tracts of forest fire occurring, at least to want to achieve "mu" quantity can be called the evil. In 1987, even like the greater hinggan mountains forest fires that disaster, although men give it as a "severe" qualitative, but how many trees were burnt, who also countless. Here, the tree as life by "grass jian". Most people think primeval forest, is the ancestors left, burn too regrettable, sends out also just sigh. Nature reserves or western drought areas, cut or destroyed burned trees, is to tree for the unit to the waste water, rubbish, oil field of erosion, makes some trees in the regreening before they wrecked his life... Calculation of, because these local trees is too precious. Goats with no tree is very desolate, people are eager for trees. In Inner Mongolia chifeng district, the tree is the government and public "eyes". The most typical example, cut down a tree is also want to disturb the local government officials, the mountain a smoke, whether burn have no burning tree, the mayor will go out. It is simple, living in sand WoZi, decades generations upon the tree planting trees, they gave too much blood, also has received the obvious effect. People will value trees, and rely on trees. "Case" are fairly clear: "home greatundertaking big", hand will loose a bit, "small small" will have carefully, if "poor" more daren't move unprofitable. From the above statement, we can see that the tree as a living "life", survival's status was in one form or another to deprived. And these "crime" behavior, exactly is our human has not been attached a blind spot. The damage to life, especially on innocent lives damage, everyone should feel guilty, including a tree, a blade of grass and all the microscopic life. But in life, human survival and development, in need and protect faced with a choice, treat tree "life" appear factitious inequality. Big to fires, disorderly denudation, small to trample on, casual damage, such examples is endless. The leaves of the dismal gradually wither, imaging whole building ground-broken. In winter trees

世界地球日(Earth Day)
Earth Day
April 22th Earth Day was first observed in Spring of 1970.An estimated 20 million people nationwide attended festivities out of which came the largest grassroots environmental movement in U.S.history,and the impetus for national legislation like the Clean Air and Clean Water Acts.By the twentieth anniversary of that event,April 22,1990,more than 200 million people in 141 countries participated in Earth Day celebrations.
Former U.S.Senator Gaylord Nelson,Earth Day's co-founder,modeled Earth Day on anti-Vietnam War demonstrations,called "teach-ins," that were common on college campuses."At a conference in Seattle in September 1969,I announced that in the spring of 1970 there would be a nationwide grassroots demonstration on behalf of the environment," says Nelson."The response was electric.Telegrams,letters,and telephone inquiries poured in from all across the country." As many as 20 million Americans participated in environmental rallies,demonstrations and other activities in the 1970 Earth Day.
Since the first Earth Day,however,the environmental movement has increasingly transformed itself from a largely grassroots,citizen crusade to a professionally-organized,established special interest.
有关环境保护的英语作文
Many people are active in fighting against unfair treatment to colored people,women ,animals and so on.Right now I am talking about fighting for respect to our environment.Though the environment doesn't have a mouth to deprecate what humans have done to her,she retaliates through action.In the early years the Chinese cut down large quantities of trees,at the source of the yellow river,which led to the disappearance of big forests and terrible floods.As a result,the Huangtu plateau which was once covered with grass and forests was turned into barrens that supported fewer plants.Another example was in several developed countries.Because many chemical factories discharged poisonous gas without filtering it,cities were covered with so much poisonous gas that people were killed by the air they breathed in.What horrible scene!What we are suffering is only a small part of what the nature once suffered.If we don't take action to show respect to the environment,we will have to face an increasingly awful situation.
Measures should be taken to protect the environment on which we are relying.First governments should forbid destroying vegetation,rivers and lakes,oceans,as and the atmosphere as well.Second voices should be made to announce the public of the importance of protecting the environment.Third enterprises should pay special attention to the effect they have on the environment and work out solutions for the problems.
Only by changing the way we treat the environment can we get along well with it.Only by saving the environment can we save ourselves.
保护水资源
As we can see,the world population is growing rapidly day by day.So enough fresh water is needed to feed such a big population.What's more,with the development of industry,factories and vehicles produce poisonous gases or wastes,which consequently results in the pollution of water.Though fresh,a good amount of it can no longer be used.Only quite limited fresh water resource is available to human beings.So it's high time for us human beings to take quick action to protect water resource.Stop pollution and save water,otherwise,we cannot survive on the earth.
With fresh water,the world will be prosperous.

环境污染概述
由于人们对工业高度发达的负面影响预料不够,预防不利,导致了全球性的三大危机:资源短缺、环境污染、生态破坏.人类不断的向环境排放污染物质.但由于大气、水、土壤等的扩散、稀释、氧化还原、生物降解等的作用.污染物质的浓度和毒性会自然降低,这种现象叫做环境自净.如果排放的物质超过了环境的自净能力,环境质量就会发生不良变化,危害人类健康和生存,这就发生了环境污染.
环境污染有各种分类：
按环境要素分：大气污染、水体污染、土壤污染.
按人类活动分：工业环境污染、城市环境污染、农业环境污染.
按造成环境污染的性质、来源分：化学污染、生物污染、物理污染（噪声污染、放射性、电磁波）固体废物污染、能源污染.
环境污染会给生态系统造成直接的破坏和影响,如沙漠化、森林破坏、也会给生态系统和人类社会造成间接的危害,有时这种间接的环境效应的危害比当时造成的直接危害更大,也更难消除.例如,温室效应、酸雨、和臭氧层破坏就是由大气污染衍生出的环境效应.这 种由环境污染衍生的环境效应具有滞后性,往往在污染发生的当时不易被察觉或预料到,然而一旦发生就表示环境污染已经发展到相当严重的地步.当然,环境污染的最直接、最容易被人所感受的后果是使人类环境的质量下降,影响人类的生活质量、身体健康和生产活动.例如城市的空气污染造成空气污浊,人们的发病率上升等等；水污染使水环境质量恶化,饮用水源的质量普遍下降,威胁人的身体健康,引起胎儿早产或畸形等等.严重的污染事件不仅带来健康问题,也造成社会问题.随着污染的加剧和人们环境意识的提高,由于污染引起 的人群纠纷和冲突逐年增加.
目前在全球范围内都不同程度地出现了环境污染问题,具有全球影响的方面有大气环境污染、海洋污染、城市环境问题等.随着经济和贸易的全球化,环境污染也日益呈现国际化趋势,近年来出现的危险废物越境转移问题就是这方面的突出表现.
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!
共筑校园和谐的蓝天
和谐,多么美好的一个词语,多么美好的意境.请让我们一起来感受一下和谐吧:春风是和谐的,她使坚冰融化,万物复苏,把人们带到美好的季节；春雨是和谐的,她“随风潜入夜,润物细无声”.古往今来,和谐思想绵绵不绝.从孔子提倡的“礼之用,和为贵”“和而不同”,到到孟子“天时不如地利,地利不如人和”的论断；从洪秀全提出的“有田同耕,有饭同食,有衣同穿,有钱同使”的理想方案,到康有为描绘的“人人相亲,人人平等,天下为公”的社会状态,从孙中山“大同世界”的理想,到毛泽东“环球同此凉热”的追求,悠悠中华几千年,历代思想家、政治家,无不推崇团结互助的理念,和谐社会始终是人们最崇高的理想. 和谐就是融洽和睦、协调发展.和谐社会应该是团结友爱、互帮互助的社会.但现实生活中,由于许多同学、思想觉悟、价值观念、利益追求、兴趣爱好的差别,有些人的行为方式不利于团结互助,甚至一些损人利己现象也时有发生；还有的同学喜欢搞小自由主义,当面不说,背后乱说,班级不说,校外乱议论,导致同学与同学之间互相猜疑,引起同学之间不和睦；甚至有的同学把社会上一些：惟利是图,损人利己,爱占便宜；甚至于尔虞我诈、坑蒙拐骗的行为,也或多或少的带到了校园,这样不仅可耻,简直可以说是道德的囚犯.胡总书记把“以团结互助为荣、以损人利己为耻”作为社会主义荣辱观的重要内容提出来,丰富了社会主义道德建设的内容,同时也丰富了我们的校园文化,我们中学生在这个富有感召力的今天,我们应该做的是；同学之间要和谐,要团结友爱互助；校园要和谐,构筑一个团结友爱、文明向上的和谐校园. 历史经验一再告诉我们：有没有团结互助的道德风尚,是判断一个群体是否健康、一个社会是否和谐的重要标志之一.继承中华民族优良的传统文化,很重要的一个方面,就是弘扬团结友爱、互帮互助的美德. 是啊!我国素以“礼仪之邦”著称于世,讲“仁爱”、行“友善”、重“人和”的传统美德.我们新一代的中学生应该传承这些传统美德、今天要为构建一个和谐的校园努力,明天我们要为构建一个和谐的社会而付出,这是历史付与给我们的重任!这是时代付与给我们的使命!
环保,从身边小事做起...
最近,北京一群中学生给朱镕基总理写了一封提倡环境保护的信,引起了总理的高度重视……扪心自问,我们每一位又何尝不应该对此深刻反省呢?
环境保护对我们来说并不是一个新问题,我国政府也早就提出了明确的治理目标.作为现实生活中的每一个普通人,虽然不可能都直接从事环保工作,但我们完全可以从小事做起,从我做起.当看到洗手间的水龙头在滴水时,是不是能够举手关上呢?当电池用完后能否分类收藏处理而不是随手扔掉呢?当购物时能否自觉不使用超薄塑料袋呢?……一件件小事虽然都很不起眼,但却体现我们究竟具备了多少环保意识.
笔者知道有一位老太太,她每次上街买菜都要自带一个小布袋,每次上餐馆吃饭都要自带一个小钢勺.看起来很平常,但能够像这位老同志那样,长年自觉坚持不使用白色塑料袋,不使用一次性筷子,确实不容易.这不但要有坚定的环保信念,还需要有良好的习惯.无可置疑,环境意识与人们的受教育程度密切相关,在大学校园里我们最容易找到环境保护的支持者.但是,我们同样也能够经常在大学的食堂垃圾桶里发现大量的剩饭剩菜.笔者还听说有这么一位大学生,他热心环保事业,曾积极奔赴云南边陲保护金丝猴,但他却可以数次忘了关掉水房里哗哗流的水龙头.这提醒我们,全面的环境保护和全民族环保意识的普及与提高,决非轻而易举；环境保护不仅仅包括动物、森林的保护、防止大气和水的污染这样一些“大事”,也包括我们周围生活中无处不在的各种小事.
人类对环境的保护,归根结底是基于保护地球上日益枯竭的资源,保护我们生存发展的最起码条件.当工业文明进入21世纪后,它对环境的破坏日趋严重,对资源的使用走向了滥用,这引起了人们越来越高度的警惕.各国政府为了保护环境,采取了许多措施,环境保护也取得了长足的进展,并且成为人类社会的共识.今天,提起环境保护,几乎没有什么人会公开反对,但是真正做到自觉长久地保护环境,保护资源,还有许多工作在等待着我们去做.我认为首要的就是要在全民族树立起环保意识,具体地说就是树立资源意识,生存意识.要让大家都认识到,保护环境与资源和我们每个人息息相关,保护环境不仅是关乎子孙后代的千秋大业,而且已经直接关系到人类社会今天的生存!不能抱着环保多我一人少我一人差别不大的思想,也不能对保护环境有任何松懈和怕麻烦的思想.政府部门对环境保护固然负有重要的责任,而每个单位,每个企业,每个人对此更是承担了更为直接、更为具体的责任.只要我们从自己做起,从小事做起,大家共同努力,持之以恒,就一定能为社会、也为自己留下一片碧水蓝天.在这一点上,北京的中学生们已经为我们提出了不少好的建议,难道我们还有什么需要犹豫的吗?
环境保护知识
什么是环境保护?
环境保护是指人类为解决现实的或潜在的环境问题,协调人类与环境的关系,保障经济社会的持续发展而采取的各种行动的总称.其方法和手段有工程技术的、行政管理的,也有法律的、经济的、宣传教育的等.
其内容主要有：
（1）防治由生产和生活活动引起的环境污染,包括防治工业生产排放的“三废”（废水、废气、废渣）、粉尘、放射性物质以及产生的噪声、振动、恶臭和电磁微波辐射,交通运输活动产生的有害气体、废液、噪声,海上船舶运输排出的污染物,工农业生产和人民生活使用的有毒有害化学品,城镇生活排放的烟尘、污水和垃圾等造成的污染；
（2）防止由建设和开发活动引起的环境破坏,包括防止由大型水利工程、铁路、公路干线、大型港口码头、机场和大型工业项目等工程建设对环境造成的污染和破坏,农垦和围湖造田活动、海上油田、海岸带和沼泽地的开发、森林和矿产资源的开发对环境的破坏和影响,新工业区、新城镇的设置和建设等对环境 的破坏、污染和影响；
（3）保护有特殊价值的自然环境,包括对珍稀物种及其生活环境、特殊的自然发展史遗迹、地质现象、地貌景观等提供有效 的保护.
另外,城乡规划,控制水土流失和沙漠化、植树造林、控制人口 的增长和分布、合理配置生产力等,也都属于环境保护的内容.环境保护已成为当今世界各国政府和人民的共同行动和主要任务之一.我国则把环境保护宣布为我国的一项基本国策,并制定和颁布了一系列环境保护的法律、法规,以保证这一基本国策的贯彻执行.
臭氧层保护
一、什么是臭氧
太阳是一个巨大的热体,表面温度高达6000℃,是地球取之不尽的能量来源.我们都知道,人类肉眼可以看到的“赤橙黄绿青蓝紫”的七彩光是可见光范围的太阳辐射,实际上到达地面的太阳光还有红外线和紫外线等.太阳辐射的紫外光中有一部分能量极高,如果到达地球表面,就可能破坏生物分子的蛋白质和基因物质,即我们所熟知的DNA,造成细胞破坏和死亡.然而,自然的力量改变了这一过程,地球的大气层就像一个过滤器,一把保护伞,将太阳辐射中的有害部分阻挡在大气层之外,使地球成为人类可爱的家园.而完成这一工作的,就是今天已经妇孺皆知的“臭氧层”.
臭氧与我们熟知的氧气是“亲兄弟”,只是臭氧由三个氧原子构成,而氧气由两个氧原子构成.由于臭氧和氧气之间的平衡,大气中形成了一个较为稳定的臭氧层,这个臭氧层的高度大约在距离地面表面15~25千米处.生成的臭氧对太阳的紫外辐射有很强的吸收作用,有效地阻挡了对地表生物有伤害的紫外线.因此,实际上可以说,臭氧层形成之后,才有了生命在地球上的生存、延续和发展,臭氧层是地表生物系统的“保护伞”.
二、南极臭氧空洞
臭氧层在大气中是极其脆弱的一层气体,如果在零度的温度下,沿着垂直的方向将大气中的臭氧全部压缩到一个大气压,那么臭氧层的总厚度只有3毫米左右.
科学家在南极地区最早发现了严重的臭氧层破坏.南极是一个非常寒冷的地区,终年被冰雪覆盖,四周环绕着海洋.在过去10～15年间,每到春天南极上空平流层的臭氧都会发生急剧的大规模耗损.极地上空臭氧层的中心地带,近95％的臭氧被破坏.从地面向上观测,高空的臭氧层已极其稀薄,与周围相比像是形成了一个“洞”,直径上千千米,“臭氧洞”就是因此而得名的.臭氧洞可以用一个三维的结构来描述,即臭氧洞的面积、深度及延续时间.1987年10月,南极上空的臭氧浓度下降到了1957～1978年间的一半,臭氧洞面积则扩大到足以覆盖整个欧洲大陆.从那以后,臭氧浓度下降的速度还在加快,有时甚至减少到只剩30%,臭氧洞的面积也在不断扩大.1994年10月观测到臭氧洞曾一度蔓延到了南美洲最南端的上空.近年臭氧洞的深度和面积等仍在继续扩展,1995年观测到的臭氧洞的天数是77天,到1996年几乎南极平流层的臭氧全部被破坏,臭氧洞发生天数增加到80天.1997年至今,科学家进一步观测到臭氧洞发生的时间也在提前,1998年臭氧洞的持续时间超过100天,是南极臭氧洞发现以来的最长记录,而且臭氧洞的面积比1997年增大约15%,几乎可以相当三个澳大利亚的面积.这一迹象表明,南极臭氧洞的损耗状况正在恶化之中.
三、臭氧洞是怎样形成的
臭氧洞一经发现,立即引起科学界及整个国际社会的震动.最初对南极臭氧洞的出现有三种不同的解释.一种认为是底层含臭氧少的空气被风吹到平流层的天然结果；第二种解释认为,南极臭氧洞是由宇宙射线在高空生成氮氧化物的自然过程；但是,美国的两位科学家Monila和Rowland指出,正是人为的活动造成了今天的臭氧洞.元凶就是我们现在所熟知的氟利昂和哈龙.
越来越多的科学证据否定了前两种假说,而证实氟利昂和哈龙产生的氯和溴在平流层通过化学过程破坏臭氧是造成南极空洞的主要原因.那么氟利昂和哈龙是怎样进入平流层,又是如何引起臭氧层破坏的呢?我们知道就重量而言人为释放的氟利昂和哈龙的分子虽然都比空气重,但它们在低层几乎不与任何分子发生反应,因此不能通过一般的大气化学过程去除.经过一两年的时间,这些物质于全球范围内在对流层分布均匀,然后主要在热带地区上空被大气环流带入平流层,风又将它从高纬度地区向低纬度地区输送,在平流层内混合均匀.在平流层内,强烈的紫外线照射使氟利昂和哈龙发生分子解离,释放出原子状态的高活性的氯和溴,生成破坏臭氧层的主要物质,它们对臭氧层的破坏是以催化剂的方式进行的.据估算,一个氯原子可以破坏104----105个臭氧分子．而由哈龙释放的溴原子对它的破坏能力是氯原子的30～60倍.而且,氯原子和溴原子还存在协同作用即二者同时存在时,破坏臭氧的能力要大于二者的简单加和.
南极臭氧空洞的形成是包含大气化学、气象学的三维复杂过程,但根源是地球表面人为活动产生的氟利昂和哈龙,氟利昂和哈龙在大气中的寿命很长,一旦进入大气就较难去除,这意味着它们对臭氧层的破坏会持续一个漫长的过程．
四、臭氧层保护
氟利昂是美国杜邦公司30年代开发的一个引为骄傲的产品被广泛用于制冷剂、溶剂.塑料发泡剂、气溶胶喷雾剂及电子清洗剂等,哈龙在消防等行业发挥着重要作用、当科学家研究令人信服地揭示出人类活动已经造成臭氧层严重损耗的时候,“补天”行动非常迅速.实际上．现代社会很少有一个科学问题像“大气臭氧层”这样由激烈的反对、不理解,
迅速发展到全人类采取一致行动来加以保护.
1985年,也就是Monlina和Rowland提出氯原子臭氧层损耗机制后11年,同时也是南极臭氧洞发现的当年由联合国环境署发起．通过保护臭氧层的维也纳公约．首次在全球建立了共同控制臭氧层破坏的一系列原则方针.
1987年,大气臭氧层保护的重要历史性文件《蒙特利尔议定书》通过．在该议定书中,规定了保护臭氧层的受控物质种类和淘汰时间表．要求到2000年全球的氟利昂消减一半,并制定了针对氟利昂类物质生产、消耗、进口及出口等的控制措施.
由于进一步的科学研究显示大气臭氧层损耗的状况更加严峻,1990年通过《蒙特利尔议定书》伦敦修正案.1992年通过了哥本哈根修正案,其中受控物质的种类再次扩充．完全淘汰的日程也一次次提前.
从这里我们不仅可以看到人类日益紧迫的步伐,而目也发现,即使如此努力地弥补我们上空的“臭氧洞”,但由于臭氧层损耗物质从大气中除去十分困难．预计采用哥本哈根修正案．也要在2050年左右平流层氢原子浓度才能下降到临界水平以下．到那时,我们上空的“臭氧洞”可望开始恢复.臭氧层保护是近代史上一个全球合作十分典型的范例.这种合作机制将成为人类的财富,并为解决其它重大问题提供借鉴和经验.
