平时没事时,我们就吃一块口香糖,嚼完后随口吐在地上,口香糖牢牢地粘在地上,清洁工人得用铲子才能把它弄掉,而且口香糖也污染土地。我们经常在购物时,会用到大大小小的塑料袋,却不知塑料袋被火烧后会制造有毒气体,填埋后还不容易降解,还会导致土地被破坏,中国人口这么多,可想而知会有多少塑料袋在污染我们的环境。

篇2:地球的环境污染
全文共 591 字
+ 加入清单保护地球作文 人类只有一个地球,它是生存的资源。地球就像我们的家园,所以我们应该要保护地球,而不是一味地破坏它。近几年来,地球的环境越来越恶劣,大片的森林被砍伐,碧绿的青山被挖掘了,美丽的大草原成了荒漠,清澈的小河变成了臭水沟。树林少了,青山秃了,草原荒了,河水黑了,人们生存的环境变坏了,呼吸的空气变差了……因此,人类的疾病也多了。 现在树林越来越少了,那是因为人们在不断的砍伐树木,所以树木才会越来越少,我们因此不能呼吸到更多的新鲜的空气,我们才会患上非典、禽流感等等疾病,使我们的体质下降,让这些病毒轻而易举就进入我们的身体。
不断砍伐树木,在台风来临时,就会抵挡不住台风,受难的不还是我们人类吗? 几年来,工厂不断增加,排放污水也在不停的增加,污水常常排放在附近的小河里,使原来清澈见底的河水变得臭气熏天。人们常常把喝完的饮料瓶随地乱扔,白色垃圾到处可见。你说,生活在这样的环境中,心情会好吗? 我们就从节约用水说起,也许大家都会说,浪费几滴水破坏不了环境。全世界每个人都浪费几滴水,如果每个人都浪费三滴水,那全世界五十亿人就要浪费一百五十亿滴水,如果把这些水送给那些干旱的地方,可以拯救多少人啊!节约用水,人人有责,所以我们大家应该节约每一滴水,不要浪费每一滴水。否则,地球上的最后一滴水将是人类的眼泪! 人类只有一个家园--地球,它是人类赖以生存的地方,我们要好好保护它。

+ 加入清单Our modern city is too crowded, and to solve the problem, three proposals are put forward. Most people believe that we should fist practise the policy “Late Marriage” and “One Couple, One Child” in order to reduce the birth rate. Secondly, the city government must have a tight control over rural people entering cities to engage themselves in trade or do various physical jobs so as to lessen the pressure on the city caused by the increased population. Finally more and more people suggest that living blocks with shopping centers, schools, hospitals as well as cinemas and theatres round them or even satellite towns should be built in city suburbs or the countryside round the cities. In this way city citizens will be encouraged to move there to live and work. If these three proposals are well carried out, the city population will be greatly reduced.
我们现代城市太拥挤了,要解决这个问题,提出了三点建议。大多数人认为我们应该在政策上“迟婚”和“一对一”,以降低出生率。其次,城市政府必须严格控制农村人口进入城市,从事贸易或从事各种体力劳动,减少人口增长造成的压力。最后,越来越多的人建议,居住在购物中心、学校、医院、电影院、剧院等生活街区,城市郊区或郊区的城市应该建在城市郊区或城市周边的城市。在这个方式中,城市居民将被鼓励在那里生活和工作。如果这三项建议都很好地实施,城市人口将大大减少。

篇8:家乡环境污染
全文共 550 字
+ 加入清单哦!家乡变了,家乡变了,我怀着无比激动的心情来到家乡。
下了车,眼睛突然一亮,哇!家乡简直是梦幻美丽的天堂。眼前,是一排排苍翠挺拔的大树,像一位位士兵守卫着这梦幻般的仙境。脚下的路更加宽阔平坦,不再蜿蜒崎岖。向前走10分钟,一条清澈见底的小溪便印入眼帘,水底的鱼虾清晰可见,它们无忧无虑地在小溪里穿梭,快乐的好像神仙一样。在阳光的照耀下,水面破光粼粼,像一面洁白无瑕的璞玉。小溪旁,是一片翠绿的草坪,几棵小草,伸着懒腰,从土地里钻了出来,探视着这五彩缤纷的世界;小花涨红了脸,呼吸着春天的香气息。
家乡的变化可真大啊!想当年,家乡的环境十分恶劣:山上,一群肌肉结实,身体强壮的年轻男子,拿着一把把锋利的电锯,无情地把高大粗壮的树木砍伐一空。生活在山林的小动物都仓皇而逃,过着定无居所的日子。生活在小溪旁的人们更受着百倍的煎熬,溪水恶臭浑浊,鱼虾奄奄一息。溪旁的小草面黄肌瘦。无精打采,小花也垂头丧气,没有了往日的生机。更恐怖的是,环境的污染使得可怕的自然灾害降临到家乡。瓢泼大雨使山体滑坡,严重的泥石流,造成了许多人财产受损。幸亏人们对家乡长生了保护意识,在荒山上植树造林,把小溪的垃圾清除一空……这才把家乡从死亡的边缘拉了回来。
我们美丽的家园需要爱,请保护环境吧!让我们的地球永远拥有美丽、青春的活力。

保护野生动物
许多野生动物正面临绝种的危险,因为它们生活的环境发生了极大的变化。譬 如,随着城市的发展,杀虫剂的使用和严重的污染,野生动物的生活区域变得越来越狭小。许多野生动物目前正面临着食物方面的危机。同时,为了获取野生动物的毛、皮、角、牙齿和肉,人类正在屠杀野生动物。
为了保护生态资源,人们应当意识到任何物种的缺失,至少意味着知识资源和自然美的缺失。因此,应采取以下措施:制订污染标准以降低有毒物质;严禁杀害某些稀有物种;应建立国家公园作为野生动植物保护区。
我们只有采取一些有力措施,才能保护野生动物。

英语作文汽车环境污染二
Too many cars have caused a lot of serious problems in our world. Besides congestion, accidents and fast fuel consumption, cars are responsible for a good part of air pollution in big cities. One possible solution is to design and develop clean cars and clean fuels. In Shanghai, some of the public buses begin to run on natural gas, which does not give off as much carbon dioxide as petrol. Another solution is to develop modern public transportation systems and restrict the use of private cars. If the price of petrol rises constantly and the public vehicles are efficient and convenient enough, most people will not buy private cars. Thus, the total number of cars in big cities will reduce greatly. On the whole, the elimination of air pollution needs the collective efforts from the government, the public and the environmentalists.

污染物对环境和生物有很大的危害,它会使空气变得浑浊,对人类的肺部也有害。生活垃圾处理不好还会产生细菌,还会影响到人类的健康。污水会影响到人类喝的水,这样的话,这些水就会直接进入到人类的身体里。
所以,我建议大家做到以下几点,一.不用一次性木筷。二.不污染水源。三.不乱扔垃圾。四.不随地吐痰。五.多植树造林。六.不践踏草坪。七.废旧电池和垃圾要处理好。八.不要用动植物的东西。
我们要保护好周围的环境,不要再让家乡受到污染。
篇19:家乡环境污染小学作文
全文共 895 字
+ 加入清单走过一条条小路,路过一条条小河,经常会看到一些垃圾,如:被吃过的水果的果皮、零食包装、塑料瓶子等,工厂和汽车放出的气体,使到处变得乌烟瘴气。大家都想知道是谁在破坏,现在揭晓答案:“是我们,人类!”
目前世界上百分之六十的地区街上都会出现有垃圾的现象,只有少数的国家有一尘不染的“美誉”,比如说:日本,日本的大街上几乎没有垃圾桶,有的话也是规定了倒垃圾的时间,其余时间不能倒垃圾,他们一般在要逛街的情况下,都会随身带个垃圾袋,以免买了东西的袋子或是遇到突发情况都不用丢脸地找别人借袋子,他们都不会像我们国家的有些人那样自私,他们每个人都有一个共同的信念:保持清洁卫生,不能让其他国家的人决得日本的卫生习惯很差!
有一种污染名叫白色垃圾,我简单介绍一下:塑料制品作为质轻,防水,防腐蚀的新型材料,在全世界被广泛运用。
塑料最早运用于农业地膜,给农业生产带来了极大的发展,可使农作物在任何季节生长,促进了市场消费。据市场统计,自1990~1995年,塑料的生产以每年8.9%的速度增长,已经席卷了整个地球。简直可以称作“白色革命”。但它在为人们提供方便的同时,也给人们带来了一场“白色灾难”。
至今,“白色污染”已经成为众所周知的一个新型名词。它主要指各种发泡塑料袋,农用地膜等给环境造成了污染,并且得到社会的普遍关注。
还有人做过统计,火灾中被浓烟熏死呛死的人是烧死者的4?5倍。在一些火灾中,被"烧死"的人实际上是先烟气中毒窒息死亡之后又遭火烧的。
浓烟致人死亡的主要原因是一氧化碳中毒。在一氧化碳浓度达1。3%的空气中,人吸上两三口气就会失去知觉,呼吸1?3分钟就会导致死亡。而常用的建筑材料燃烧时所产生的烟气中,一氧化碳的含量高达2。5%。此外,火灾中的烟气里还含有大量的二氧化碳。在通常的情况下,二氧化碳在空气中约占0。06%,当其浓度达到2%时,人就会感到呼吸困难,达到6%?7%时,人就会窒息死亡。另外还有一些材料,如聚氯乙烯、尼龙、羊毛、丝绸等纤维类物品燃烧时能产生剧毒气体,对人的威胁更大。
所以,我想提醒大家:“千万不要破坏环境,害人害己,而且对自己的身体没有好处!”
