水污染演讲稿范文有没有？

今天我发言的题目是《应加大水资源的保护力度》。
众所周知，我国是一个干旱缺水严重的国家。我国的人均水资源只有2200立方米，仅为世界平均水平的1／4、美国的1／5，在世界上名列121位，是全球13个人均水资源最贫乏的国家之一。水资源的无序开采和严重污染，加剧了其供需矛盾，对正在实施的可持续发展战略带来了严重影响。
如今，地域辽阔、资源丰富的塞外赤峰也已成为缺水地区之一。赤峰市人均占有水资源量已不足900立方米，仅为全国人均水资源占有量的40%，是全自治区人均水资源占有量的41%，远远低于国际公认的人均1700立方米的用水安全线。而“十年九旱“已成为我地去的气候特点，旱魃为虐，随之而来的是赤峰大地河流中断、湖泊干枯，地下水位严重下降。使得我们不得不把水资源的保护与利用上升为战略性高度，作为民生问题对待。
严峻的现实使我们认识到“水“不再是“取之不尽、用之不竭“的资源，每个塞外赤峰人都陷入沉沉的思考：目前赤峰市水资源究竟危机到什么程度？地上和地下水资源缺
乏给农牧业生产乃至人民生活造成多大影响？政府乃至民众应采取哪些应对举措，才能扭转危机局面？
下面，我以阿旗为例分析水资源现状。
一、水量逐渐减少客观原因是：丰枯悬殊，年际季节变化大，全旗年降水主要集中在6—8月份，约占年降水量的75%，多年平均降水量308.1mm，年际降水变率大，1998年降水562.4mm，20xx年仅为117.5mm；分布不均，导致水资源不丰富，并且地表水资源开发利用难度较大；植被覆盖率低，水土流失严重使得土地蓄水、保水性能极差；连年干旱致使四条主要河流已常年断流；基础设施薄弱，蓄水能力差，导致无法利用自然降水，只能依靠地下水来发展农牧业和工业。目前，我旗灌区灌溉水利用系数仅为0.5左右；水位逐年下降且不断加快，城镇地下水以每年2米的速度下降，从20xx年至20xx年为止，已下降10米。
主观原因是：人为因素已成为水

Dear Sir or Madam,
I’m writing to you to state my view on the water pollution problem.It is generally accepted that water pollution is a serious public hazard today.Rivers all over the world are becoming polluted with garbage and dangerous chemicals.Ships contribute to the problem because they rely on rivers for disposing of wastes.Oil and other chemicals can kill fish and make water unsafe for drinking.Because they rely on rivers for disposing of wastes.Oil and other chemicals can kill fish and make water unsafe for drinking.In a word, polluted water is a big problem to everyone.From joozone.com.
As you know, people depend on water to live on.They should be involved in finding a solution to this problem.I think, certain counter measures need to be taken as soon as poible.To begin with, the governments of all countries are supposed to formulate rules and regulations to deal with the pollution problem.In addition, factories in towns and cities must be prohibited from draining waste liquids into rivers before they are totally treated and purified.I feel if they violate relevant rules or laws, they should be fined heavily.Certainly, there are some other cures which are worth adopting.
