英语演讲稿 有关节约用纸
Teachers and students:Good morning!I'm worried about my country.There is polution everywhere.It's time to do something about it.I remember that at the beginning of my coming to America, I often went to my father's working place, the United States Geological Survey, to have fun. Each time I found a lot of people riding bicycles to their offices. Among the cyclists, an old man with white hair attracted my attention. Curiously, I asked my father, Why does the old man ride his bike to work every day? Doesn't he have enough money to buy a car? Father laughed, No, not because of money. Actually, he is one of the greatest scientists in the world. He can afford to buy a motorcade if he likes. He is just an environmentalist and usually doesn't drive unless going shopping, or in bad weather. In America, there are a lot of environmentalists, who actively protect their environment. For example, in Palo Alto city we are living now, there is even a bicycle-to-work day on May 19th every year to encourage people to decrease air pollution caused by cars. We need fresh air to breathe.We need pure water to drink.We need a clean environment to be healthy. People have to stop littering.We have to respect our surroundings.We must become friends of the earth.First,everyone must get involved.Everyone must lend a hand.Together we can clean up our neiborhoods.Second,we can practice conservation.We can reduce waste and reuse things.We can recycle paper,bottles,and plastic.Third,we can put up more Don't litter signs.We can trashcans on every corner.We can pick up garbage when we see it.We must take action to fight pollution.It's our future we're protecting.It's our duty to keep our planet clean.So,please don't pollute.Don't be a litterbug.Don't be afraid to remind others,too.Let's protect nature's beauty.Let's make our future bright.Let's start to clean up now.
请告诉我节约用纸的演讲稿
节约用纸 保护环 纸的发明人类文明的伟大贡献，目前生产的纸约有500种。
随着我国改革开放现代化步伐的加速，人们经济文化水平的提高，对纸张的需求猛增。
我国人均每年耗纸量约10公斤。
造纸的原材料主要是树皮等植物的纤维。
森林是大自然的清洁工，在保护环境方面，森林的生态效应大大高于直接经济效益，例如：森林是制造氧气的工厂，森林能够吸收有害物质，森林能够保持水土，森林能够涵养水源，树冠像一把张开的伞，可以截留10~20%雨量。
5万亩森林贮水量相当于100万立方米的小型水库。
节约纸张，回收废纸可以大大降低原材料的消耗。
废纸张是生活垃圾的一部分，在中国的垃圾构成中，纸类占17·99%。
据有关资料统计：少浪费1500张纸，就可以保留一棵树，少浪费一百万张纸，意味着节约680棵树；一个办公室节约6吨纸垃圾，相当于拯救120棵树。
国外有一个颇为流行的抵御垃圾侵害的四R措施，是提供保护环境，抵御垃圾侵害的新哲学的一个口号。
实际上，它的意思是：减少（REDUCTION），再循环（RECOEY），回收（RECYCLE）。
随着垃圾日益增多，全世界都面临着垃圾包围的危险。
比如，70年代以来，北京市共做了三次航空遥感观测，发现沿三环、四环50平方米以上的垃圾堆竟有7000多个。
您如何看待垃圾，又如何看待垃圾的处理问题
其实，我们对垃圾，包括纸张、废塑料等等，更习惯于把它们看成是一类放错位置的资源我们之所以习惯于这样说，是因为，某些人对垃圾的认识是错误的。
有相当一部分的垃圾有着一定的重复使用价值，而由于科学的局限，人认识的局限，我们并没有达到所谓的物尽其用。
至于垃圾处理。
目前我们中国只有2%的垃圾被回收。
如果我们不想让自己生活在垃圾中，我们就必须放弃使用--丢弃的模式，而采取使用--回收的模式，如果我们不约束自己，大自然就会惩罚我们。
我们只有一个地球，让我们从自身做起，从节约每一张纸做起，珍惜和保护我们的生态环境。
