生态环境之环境污染.docVIP

生态环境之环境污染 美丽的地球现在已经被污染得不成样了。如果我们再不努力去拯救地球的话，这个地球总有一天会被我们自己毁灭! 目前环境污染也算是毁坏地球美丽的杀手之一，而且是第一杀手。 环境污染也分好几种“小杀手”。第一种，水环境污染：以前地球有很多清澈的小溪，可是现在那些澈的小溪大部分都被污染了：以前清澈的小溪有许多活泼乱跳的小鱼，可现漂着的是鱼骨头,死鱼；以前清澈的小溪可以供人们洗澡，饮用等，可现在人们连碰都不敢碰。为什么会这样？因为大部分的小溪旁边或者后面都有一些工厂，这些工厂每天都会排出一些废水，而且人们不懂得珍惜小溪的清澈，每天都会随手往溪里乱扔垃圾，导致溪水被污染。第二种，垃圾污染：现在虽然有很多人都在说垃圾分类的重要性，可现在垃圾污染还是很厉害。为什么呢？因为他们都是口头上说说，行动上却没有。比如说：现在有很多小学生都会说：“能卖拿去卖，有害单独放，干湿要分开！”他们在学校承诺回家会做好垃圾分类，可是一回到家就把这件事抛到九霄云外。也有很多人懂得垃圾分类，也会动手做，可就是有时会忘了，有时突然不想做，就又会乱分、乱扔。 其实环境污染对我们的伤害真的很大：环境污染会给生态系统造成直接的破坏和影响，比如：沙尘暴，森林破坏、砍伐。有时会给人类造成间接的危害，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 所以，美丽的环境是需要大家去维护的，让我们一起去保护我们的地球吧！The environmental pollution of ecological environmentThe beauty of the earth has now been away to a kind of pollution. If we dont try to save the earth, it will one day be destroyed by ourselves!At the moment one of the environmental pollution is destroying the earth beautiful killer, and is the first killer.Environmental pollution is several small killer. The first kind, water environmental pollution: The earth had a lot of clear brook before, but now most of the clear stream is polluted. There were many lively fish in the clear brook before, but itis now floating fish bone, dead fish. Limpid streams could be for people to take a bath and drinking, etc., but now people are afraid to touch them. How did that happen? There are some factories near or behind most of the streams. And some waste water discharges from the factories every day. And that people dont know to cherish the clear streams. People throw rubbish into the stream every day, and it leads to water contamination. Second, the garbage pollution: Although there are a lot of people are saying the importance of garbage classification, now garbage pollution is still severe. Why is that? Because they are both verbally , but no action. For example, now a lot of primary school students say , “Can sell to sell, harmful put alone, dry wet to separate!” They promise to do home garbage classification in school, but when they get home , they just throw it to the outside of the cloud . Many people know the garbage classification, they will begin to do it , but they sometimes forget it , they sometimes dont want to do that, and then they are randomly classified trash and litter. Environmental pollutionis really harmful to us. Environment pollution can cause direct damage to the ecological system, such as dust storms, forest destruction, cutting down. The pollution of the environment sometimes is indirect harmful to human beings. Sometimes indirect harm to humans, the harm of the indirect environmental effect than the more direct damage, and much harder to eliminate. For example, the greenhouse effect, acid rain and ozone depletion is derived by atmospheric pollution environment effect. The environmental effects derived from the environmental pollution has lag, often occur in pollution is not easy to detect or anticipated at the time, however, in the event of means hav
