More and more countries are trying to work out some effective means to bring it under control， but no great success has been The environmental protection is the most major problem which in the modern life the humanity Must solve this problem must start from First， must massively propagandize， enhances people's consciousness with understanding， strengthens the environmental protection Next， must carry on waste recovery use， reduces to forest-tree's Also must strengthen to white pollution processing， little uses the plastic Finally， must make improvement to clean Causes the city's appearance to be For

As everyone knows ， the environment has become worse and worse because people cut down more trees ，throw the waste everywhere and many factory put the dirty water into the It causes many serious Now river dirty， dirty air， the temperature So we must protect our environment We can plant more trees and throw the waste into the litter and so We only have one earth Let's put our effort to protect our environment

Water pollutionWater pollution is a major problem in the global It has been suggested that it is the leading worldwide cause of deaths and diseases， and that it accounts for the deaths of more than 14，000 people An estimated 700 million Indians have no access to a proper toilet， and 1，000 Indian children die of diarrheal sickness every Some 90% of China's cities suffer from some degree of water pollution， and nearly 500 million people lack access to safe drinking In addition to the acute problems of water pollution in developing countries， industrialized countries continue to struggle with pollution problems as In the most recent national report on water quality in the United States， 45 percent of assessed stream miles， 47 percent of assessed lake acres， and 32 percent of assessed bay and estuarine square miles were classified as pollutedWater is typically referred to as polluted when it is impaired by anthropogenic contaminants and either does not support a human use， like serving as drinking water， and/or undergoes a marked shift in its ability to support its constituent biotic communities， such as Natural phenomena such as volcanoes， algae blooms， storms， and earthquakes also cause major changes in water quality and the ecological status of Causes of water pollutionThe specific contaminants leading to pollution in water include a wide spectrum of chemicals， pathogens， and physical or sensory changes such as elevated temperature and While many of the chemicals and substances that are regulated may be naturally occurring (calcium， sodium， iron， manganese， ) the concentration is often the key in determining what is a natural component of water， and what is a Oxygen-depleting substances may be natural materials， such as plant matter ( leaves and grass) as well as man-made Other natural and anthropogenic substances may cause turbidity (cloudiness) which blocks light and disrupts plant growth， and clogs the gills of some fish Many of the chemical substances are Pathogens can produce waterborne diseases in either human or animal Alteration of water's physical chemistry includes acidity (change in pH)， electrical conductivity， temperature， and Eutrophication is an increase in the concentration of chemical nutrients in an ecosystem to an extent that increases in the primary productivity of the Depending on the degree of eutrophication， subsequent negative environmental effects such as anoxia (oxygen depletion) and severe reductions in water quality may occur， affecting fish and other animal

Nowadays， the biggest problem in our world is the environment is The environment around us gets worse and worse， and the environment pollution is becoming more and more serious all over the Many lakes and rivers are seriously polluted and much water is polluted by Many trees are cut down， and the animals don’t have home to The earth is our home and it is our duty to take care of it for ourselves and our future Good environment can make people feel happy and And the bad environment will bring illness to To protect the environment means to improve our As a middle school student， we must do our bit towards protecting the It is our duty to do But what can we do for our Mother Earth? In my opinion， I think protecting the environment should from We shouldn’t throw the rubbish And we should also tell others not to do We should put the trash into their own houses—trash Whenever and wherever we see litter on the ground， we should pick it up and throw it into trash Never spit in And don’t draw on public As we know， water is the limited resources， and it is very important for human beings， we can’t live without But some people don’t care about it， and many cities need water So we shouldn’t waste the How to save the water? I have some my own First， we can use some water which we have used For example， we can use the water we wash rice to water the Second， we should turn off the tap when we We should try to protect the water To protect trees， we can go to plan as many trees as we We can use cloth bag instead of plastic bag while we are And I think we should tell others to protect environment， We should stop the people who throw the trash on the ground， and tell them it’s wrong to do We can also write to the boss of factories which discharge the We can call our friends to plant more flowers and trees We should let people realize the seriousness of the environment “There is only one earth，” I hope everyone will protect the If everyone makes their contribution to protect the environment， our earth will be more and more beautiful!

英语论文3000字有关水污染怎么写

自己去翻译吧地球的储水量是很丰富的，共有5亿立方千米之多。地球上的水，尽管数量巨大，而能直接被人们生产和生活利用的，却少得可怜。首先，海水又咸又苦，不能饮用，不能浇地，也难以用于工业。其次，地球的淡水资源仅占其总水量的5%，而在这极少的淡水资源中，又有70%以上被冻结在南极和北极的冰盖中，加上难以利用的高山冰川和永冻积雪，有87%的淡水资源难以利用。人类真正能够利用的淡水资源是江河湖泊和地下水中的一部分，约占地球总水量的26%。全球淡水资源不仅短缺而且地区分布极不平衡。按地区分布，巴西、俄罗斯、加拿大、中国、美国、印度尼西亚、印度、哥伦比亚和刚果等9个国家的淡水资源占了世界淡水资源的60%。约占世界人口总数40%的80个国家和地区约15亿人口淡水不足，其中26个国家约3亿人极度缺水。更可怕的是，预计到2025年，世界上将会有30亿人面临缺水，40个国家和地区淡水严重不足。中国水资源总量为8万亿立方米。其中地表水7万亿立方米，地下水83万亿立方米，由于地表水与地下水相互转换、互为补给，扣除两者重复计算量73万亿立方米，与河川径流不重复的地下水资源量约为1万亿立方米。按照国际公认的标准，人均水资源低于3000立方米为轻度缺水；人均水资源低于2000立方米为中度缺水；人均水资源低于1000立方米为严重缺水；人均水资源低于500立方米为极度缺水。中国目前有16个省(区、市)人均水资源量(不包括过境水)低于严重缺水线，有6个省、区(宁夏、河北、山东、河南、山西、江苏)人均水资源量低于500立方米。中国水资源总量并不算多，排在世界第6位，而人均占有量更少，2240立方米，在世界银行统计的153的国家中排在第88位。中国水资源地区分布也很不平衡，长江流域及其以南地区，国土面积只占全国的5%，其水资源量占全国的81%；其以北地区，国土面积占全国的5%，其水资源量仅占全国的19%。面临这严峻的水资源形势，我们是该做些什么了： 1、要有惜水意识，长期以来，人们普遍认为水 “取之不尽，用之不竭”，不知道爱惜，有的甚至将水白白浪费。应当知道我国水资源人均量并不丰富，地区分布也不均匀，而且年际差别很大，年内也变化莫测，再加上污染，使水资源紧缺，自来水更加来之不易。爱惜水是节水的基础，只有意识到“节约水光荣，浪费水可耻”，才能时时处处注意节水。 2、养成好习惯，据分析，家庭只要注意改掉不良的习惯，就能节水70%左右。与浪费水有关的习惯很多，比如：用抽水马桶冲掉烟头和碎细废物；为了接一杯热水，而白白放掉许多冷水；先洗土豆、胡萝卜后削皮，或冲洗之后再择蔬菜；用水时的间断（开门接客人，接电话，改变电视机频道时），未关水龙头；停水期间，忘记关水龙头；洗手、洗脸、刷牙时，让水一直流着；睡觉之前、出门之前，不检查水龙头；设备漏水，不及时修好。 3、使用节水器具，家庭节水除了注意养成良好的用水习惯以外，采用节水器具很重要，也最有效。为了省钱，很多人宁可放任自流，也不肯更换节水器具，其实，交这么多水费长期下来是更不合算的。使用节水器具，既省钱，还能保护环境，岂不是一举两得？节水器具种类繁多，有节水型水箱、节水龙头、节水马桶等。随便用上几个就为节水做出了不少贡献啊！ 4、查漏塞流，在家中“滴水成河”并非开玩笑。要经常检查家中自来水管路。防微杜渐，不要忽视水龙头和水管节头的漏水。发现漏水，要及时请人或自己动手修理，堵塞流水。一时修不了的漏水，干脆用总开关暂时控制水流也好。管好水龙头，把水龙头的水门拧小一半，漏水流量自然也小了，同样的时间里流失水量也减少一半。就生产而言，特别对一些高消耗水的行业，我们要围绕如何优化水系统的运行，如何提高循环水的浓缩倍数，如何提高水资源的循环利用等作为节水工作的重点，积极组织技术攻关，提高水的综合利用率；同时制定切实可行的操作制度，对产品水消耗实行定额管理，并作为一项技术经济指标进行考核，减少浪费现象。长期以来，大多数人有节约用水的理念，但缺少具体的行动，大手大脚的现象还比较普遍。一些人认为家大业大，再加上身处长江边，总认为这源泉取之不尽，用之不竭，缺少节水的紧迫感和忧患意识。如果真正到了“水比油贵”之时，我们再抓节水工作就悔之晚矣
