teachers, students, hello, everybody!
each of us has a family, also love their home, but you know we have a common house? - that is our planet! earth is our common "home", and is a very beautiful home, then there is blue sky with white clouds, a tree with red flowers, birds contention, how beautiful all the ah, but that we have not thought about how to protect the earth ? october 15, 2003 astronaut yang liwei and the family telephone said excitedly, "i - see our beautiful home", which sounds from space, how many chinese people moved, the number of foreigners yeah.
today, however, when we again face the "beauty of our home", we can also say? blue sky, how life used to be a brilliant landscape, now trapped in the gray, the clean air become very close to a desire to dream. faced with an increasingly serious air pollution, looking at the sky, you say? know of a small village called demonstration of field do? the place was surrounded by the castle peak, green river flows, a beautiful place ah! however, the villagers are aware of the environment, no one important, they are deforestation, land reclamation, deforestation, forest gradually disappeared, the stream gradually dry, well water gradually withered. today, this no longer see the mountains and never see green water, and the village people use very little water, wash your face, then keep feet, and finally carefully pour the water in a vat .... .. keep pouring in ah ....... this is a natural right to their punishment, which is the earth for their ambitions ah!
students is only one earth. earth is our lovely "home"! let us join hands, for our home planet to create a better tomorrow.
when the earth has no green,whentheriverhasnowater,when the bird has no home,when all the flowers wither，will we be ashamed!
whose mind is numb,whose hand made the disaster powerful，people, people, don‘t make small profits,kneel to selfish desires，you see, the tree has been cut down,dust storms make the sky cry;
you see, the sewage overflowing by the stream,let the free fish lose the dignity of life;you smell, the air stinks,it is invading our healthy lungs，how many times of unrestrained demands,destroyed the vegetation on which we live，how many times of crazy greed,let our home face destruction，friends, friends, wake up,send the most sincere repentance to the earth。
put down the axe to be raised,let the big tree become a fortress to protect the wind and sand;close heavily polluted workshops,let the spring water irrigate the full ears of wheat;
push down the chimney emitting turbid gas,let the birds fly gently with the colorful clouds singing，we should return love with love,a sincere awe of nature，today, we should start from scratch,engrave the awareness of environmental protection in your heart，with our actions and wisdom,make the grass green and the landscape picturesque,make the blue sky bluer and the four seasons charming;makethevillagepeacefulandthecitybeautiful,
let life be harmonious and the environment beautiful，only in this way can we be worthy of our mother,worthy of children and grandchildren!
we live in the world every day. we eat food, drink water, wear clothes, watch tv, use computers and so on. we are producing waste every moment.
generally speaking, there are four sorts of waste. they are material waste, organic waste, inorganic waste and poisonous & harmful waste. now, we are going to talk about each sort of waste one by one.
material waste: it means the waste of substance or things from which something else can be made. for example, people throw away the used metal products and buy a new one, so the old metal waste accumulates. at last, they become waste. for example, when people finish reading newspaper, the paper will become waste. when the glass is broken, it also becomes waste. nobody wants to use a broken window or drink with a broken glass or wear a pair of broken glasses. once it is broken, it becomes waste. the rate of using plastics is increasing day by day. people use plastic bags because they are convenient. when they get home, they throw the plastics way, paying no attention to the environment. the more convenience plastics brings to us, the more plastic waste is produced. this is called “white pollution” as most plastics are white. some of our products we use every day are made of rubber, just like the tyres and the bottom part of our shoes. it’s true that rubber plays an important role in our life. however, it also brings us some trouble when it has been used for a long time and becomes old. the old tyres become waste because it can’t break down by nature. this is really a big problem.
environmental problems are becoming more and more serious all over the world.
for example, cars have made the air unhealthy for people to breathe and poisonous gas is given off by factories. trees on the hills have been cut down and waste water is being poured continuously into rivers.furthermore, wherever we go today, we can find rubbish carelessly disposed. pollution is, in fact, threatening our existence.
the earth is our home and we have the duty to take care of it for ourselves and for our later generations. fortunately, more and more people have realized these problems. measures have been taken to cope with these problems by the government. laws have been passed to stop pollution. i hope the problem will be solved in the near future and our home will become better and better.
as we all know the challenge and opportunity always confused with hope in the 21st century is also twin human facing challenges period. special performance in this aspect of the relation between man and nature. human deforestation blind development farming damaging the vegetation causes soil erosion desertification any natural resources make the underground mining mineral deposits in the increasingly exhausted wastewater and waste exhaust gas emission make continuous natural environment seriously deteriorating.
human nature is excessive to take suffer the nature ruthless retaliation: hurricane rainstorm storms floods and drought insect heat forest fires earthquake etc. the world because of drought disaster equipoised reasons caused the transference refugees until 2025 reach 100m. painful ecological lesson has attracted the attention of the world and all mankind ioc commission inspection bid cities improving the eco-environment is one important content. china has issued a lot of environmental protection policies and regulations. our country also attaches great importance to the protection of environment education the "building a green campus activities" in the country for grandeur.
students our school is always in advocating "green wanli" which is one of important content protection beautify our campus. we often see many students on campus each picking up litter with our own hands to protect a beautiful campus. however we also often see some we dont want to see their scenario: the playground stairs corridor have the paper scraps the profession. again see the lawn some classmates in trample the schools green belts sometimes found to have deep foot-prints some places even gone became trail.
my fellow students we is the 21st century master awareness of environmental protection is modern signs. we must have the era of responsibility. responding to global focus on the side based on the campus. many curved waist dont pick up peel confetti throws anywhere disorderly vomit more step dont cross green belts grassland. "kindness small and not for is a sin to steal a pin" starts from me since the childhood starts from the side with starting from now. to protect the earth mother purify the campus.
