大家好,我是大一(10)班的__。
首先我给大家一些数据。
美国国家大气研究中心研究员预计,由于全球气候日益变暖,覆盖北极圈70%面积的冰层正逐渐融化,按照这个速度进行下去的话,在未来30年到50年内,几乎所有北极冰层都会从地球上消失。
能源开采的速度越来越快,据预算,煤炭还可以有100年,石油只有50年将几乎耗尽。而水资源耗尽速度比石油还快。地球上可被人类利用的水源仅占总水量的十万分之七,新华社北京3月21日电,20世纪,世界人口增加了2倍,而人类用水增加了5倍。世界上12亿人用水短缺,30亿人缺乏用水卫生设施,每年有300万到400万人死于和水有关的疾病。联合国粮农组织20__年6月13日发表声明全世界每年浪费的粮食数量达到13亿吨。倘若这些粮食中有四分之一能够得以保留,就足以养活全世界目前约为9亿的饥饿人口。
不仅这些,大气污染,臭氧空洞等等问题都在威胁着人类,逼迫我们思考生死。
面对这些令人震撼的数据,作为大学生,我们能做些什么呢?
在食堂用餐时,建议饭量小的同学饭和面条可以盛的少一点,以免造成不必要的浪费,如果不够的同学可以提出多盛一点。另外,每次用完水应该确保水龙头关紧,免得白花花的水流走。我还建议每个班级配备一个放同学用剩的本子和草稿纸的箱子,以及放饮料瓶的箱子,全校定时组织卖掉,费用还可以作为班费。我们的考试用草稿纸可以用再生纸,以便形成一个良性的环保循环。
新世纪的大学生,我们的目光如果只是自己和当前,觉悟就太低了。为了未来和太阳的照常升起,我们从身边做起,不要再用饮水机里的水洗手洗杯子了,不要再用饮水机里的热水来捂手了。环保也不能流于形式,三分钟热度,或者为了环保而环保,千万不能让最后一滴水是人类的眼泪这个预言实现。
我想,我在这里说这些,并不能一下子改变一切,这关乎责任心的问题。环保的理念,必须从心底感化和植入,让人们从内心认可。我们的行为展现我们的责任心,我在此作出倡议,希望大家可以一起做一个环保主义者,保护环境,影响他人,带动他人。
我的讲话完了,谢谢大家。
Hello:
everyone!Now I want to talk about a beatiful world!
When I was young,I always dreamed that I lived in a beautiful country. There were many flowers and trees around our city.We counld hear the birds singing and see the children dancing. The streets were clear and the the air was very fresh! How nice it was!But that only was a dream of mine!How I wish that it would be come true! So I think we should do something to protect our environment. Everyone should make a contribution to protect the environment.
Taking care of our environment is very important.Wherever you live,you can do something around your neighbourhood.
Have you ever thrown any litter onto the ground?Have you ever drawn pictures on public walls?Have you ever spat in a public place?Have you ever cut down trees?If your answers are "No",it means that you have already helped protect our environment.
It is our duty to keep our envionment clean and tidy. You might ask yourself,"Have I ever picked up some rubbish and thrown it into a dustbin?Have I ever collected waste paper or bottles for recycling?Have I ever planted any trees or flowers in or near my neighbourhood?"If your answers are"Yes",it means that you have already done something useful to improve the environment.
Now I want to say :Let's do our best to make our world more beautiful!
