Paper on light analysis of dunes
Sunshine and rain are the hope of flowers; Pine and cypress are the hope of evergreen all the year round; Youth is the hope of the motherland's prosperity. Elegant environment, the first thing that comes to mind is the words clean and tidy, green and environmental protection. Breathing fresh air and looking at the beautiful scenery in front of you are really comfortable. In the flower beds on both sides of the road, pines and light green boxwood sway from side to side in the spring breeze.

Usually, when you take out the garbage in your community, you may find that most communities have at least four garbage bins side by side, which will read: kitchen garbage, recyclable garbage, harmful waste and other garbage. This is the garbage classification now. Now with garbage sorting, it can reduce the floor space and environmental pollution, and also turn some recyclable garbage into treasure. Creating a garbage-free society really only needs us to lift a finger.

Everyone saves a little every day, for example, office workers who are close to home can go to work by bike instead of driving, and choose trains instead of planes for short trips. Then a little saved by each of the 6.5 billion people in the world will come together in one day and become a lot. Saving resources and reducing exhaust emissions is a theme advocated by all of us, but it is useless to always take these principles and university questions as slogans. We need Qi Xin to work together and start with the little things in life.

Saving water resources is an important issue that our country attaches great importance to. There is a well-known water-saving slogan: "Don't let your tears become the last drop of water on the earth". In fact, this is not an exaggeration. When the water resources are really gone, it's too late for you to cry. At that time, what good life can we talk about? In fact, Taomi water is a great detergent, which can be reserved for washing dishes. Water for washing hands, bathing, washing clothes, washing vegetables and relatively clean dishwashing water can be collected for cleaning floors, washing rags and flushing toilets.

There are many cool, fashionable, beautiful and expensive cars and sports cars on the market now, and many rich people, big and small, have to spend this money to buy a "face". But is this really the so-called "face"? This is vanity, waste and luxury. Environmentally friendly gasoline and diesel can improve the performance of cars. It can clean the engine of the car, reduce the friction of the engine and make the fuel burn more fully, thus reducing air pollution. Cars should be environmentally friendly, generous, dignified and practical, and reduce carbon dioxide emissions.

At present, it is the period when the winter tiger is raging, either cloudy, snowy or sleet. In this weather, as long as it is a family with a little well-off foundation, it will turn on the air conditioner to keep warm. But as long as you do more exercise and check whether the gap between doors and windows is closed, you can reduce the time and frequency of turning on the air conditioner. Also, even in winter, you need to open the window to ventilate and let the air circulate. You can't stay together all the time, or you will catch a cold.

Sadly, Mother Earth thinks people will wake up. However, she was wrong. The pace of human destruction of the earth has not stopped, and it is getting worse. This time, for self-interest, the factory did not pay attention to protecting the environment, and even discharged sewage into the river. The fish suffocated and the pebbles sank. People have built tall buildings on the former growth base of trees, dense forests have disappeared and buildings have sprung up. "The riverside is as green as blue" can only be a beautiful memory. It is sad and ridiculous that people pass by the river and hide their noses and run away. All kinds of animals have lost their natural living environment and nutrition and are on the verge of extinction. The war is still going on, everywhere is filled with smoke and lives are destroyed. Have they ever thought that all this is caused by themselves! The exhaust gas from the factory roof is also "not to be outdone". Thick smoke turned the white clouds in the sky into "dark clouds" and acid rain began to fall. These waste gases and pollution in life make the global temperature warm, leading to the greenhouse effect.

To this day, mankind still doesn't know how to love peace. Mother Earth's beautiful coat has been torn, and her strong body has become increasingly emaciated ... Let's keep a sensitive heart of loving ourselves and respecting life, listen to the voices of earth residents, protect our only earth, and help ourselves, others and the earth together!

I love life, and I prefer dripping water. Boil a pot of clear spring water on the stove every day, which is sweet and refreshing. It is this water that has watered our lives for thousands of years.

In fruits, vegetables, crops, flowers, grass, fields, rivers ... it is everywhere, constantly changing all kinds of States, rain, snow, steam, are your gestures, you are so ordinary, we have you as naturally as we have ourselves. However, your broad mind and changing body, when you flow through the dirt, you wash them, but leave the harm to yourself; When you flow through the sewage channel of the factory, it is fatal, and you hurt it! When you float back to the blue sky, you encounter waste gas. How can your pure soul endure their swallowing? Did you cry?

This is because we hurt you. You gave us too much and we gave you too little. We can't fail you. After washing the vegetables, we will water the fields for you so that the crops can absorb you again. In the factory, we will no longer discharge waste water into your arms; We won't let smoke fly into the blue sky and give you back your pure soul. This is our yearning, and we will make further efforts to invent scientific methods, just as you treat us.

Look at it! Farmers care for you with their hard sweat and baptize you more pure and fearless; Workers protect you with their hard work and don't let sewage persecute you; Scientists spend their whole lives protecting you and developing ecological pesticides and fertilizers; The most respectable thing is our soldiers in white, who insist on working for eight hours in a row, enduring the limit of life and not letting a little toxin enter your body.

Because, we already know that you are ordinary but too precious. In the river, your body becomes thinner and thinner. In the hot summer, Miao Miao's hope for you is dying, but you don't come to see it. You make us wait so anxiously, even the kindest mother earth is irritable, and the wind and sand all over the sky are all because of your absence. We will build canals and dams, cherish you and take root in trees to raise you.

Turn the desert into an oasis; Make the grass fatter and the trees greener; The water in the river is flowing happily, and it brings us food and goods. Open the dam and water the farmland during drought; Artificial rainfall, sprinkled on the earth; If you are fierce, let it be tamed and let people generate electricity.

Let us have you, but we should cherish you and return your pure soul and unyielding incarnation to you.

2 1 century calls for environmental awareness, green mountains and clear waters, pure blue sky ... this is the responsibility entrusted to you and me by the times. We only have one earth! While cherishing life, what human beings need more is environmental protection!

Do you know what festival is March 12 every year? (Arbor Day)

So who knows which country made the earliest Arbor Day in the world? (The earliest Arbor Day in the world was made in Las California, USA. )

When was it formulated in China? In February, the 6th meeting of the 5th the NPC Standing Committee in China decided to designate March 12 every year as the Arbor Day in China. )

Students, do you know what forests do? Provide us with wood, fruits, medicinal materials and industrial raw materials, and also adjust the climate, reduce noise, purify the air, prevent wind and fix sand.

Yes, forests have many functions. It is said that four billion years ago, when the earth was just born, hot carbon dioxide gas gathered on the surface of the earth, with a temperature as high as 540 degrees Celsius. At that time, there were sandstorms everywhere and nothing. Due to the stability of the earth's crust, the temperature drops, green plants are born, life begins, and animals and people are born. Green plants provide various conditions for human survival and compose a song of life that resounds through the sky. However, due to people's deforestation, the global forest area is getting smaller and smaller.

Students, do you know? In addition to the shrinking forest area, we are also facing many environmental problems. What else would you think? Air pollution, water pollution and soil pollution. So how are these pollutions caused?

1972 On June 5th, the United Nations held the first conference on human environment in Stockholm, Sweden. The Declaration on the Human Environment was adopted, and the slogan "There is only one earth" was put forward, calling on governments and people of all countries to make joint efforts to protect the living environment of mankind. It is decided to designate June 5th of each year as "World Environment Day".

Protecting the environment is everyone's responsibility. How should we start from the little things around us?

Modern life is full of many disposable articles: disposable tableware, disposable tablecloth, disposable diaper, disposable toothbrush, disposable scraper, disposable pen, disposable camera ... disposable articles bring temporary convenience to people, but pay a high price for the ecological environment; They have accelerated the depletion of the earth's resources and brought disasters to the earth. Using less disposable goods and more durable goods should become a new social atmosphere and a new way of life. Although choosing this fashion is a trivial matter in life, it can reflect our awareness of environmental protection. Because we don't want to use the resources overdrawn to future generations to create our own temporary convenience. Let's get rid of the temptation of "one-time consumption" and enter the era of repeated use and sustainable development.

Who will tell a short story about environmental protection? Let me tell a story first. The name of this story is grass and tree. )

One sunny afternoon, there was silence all around, and the grass and trees were talking. Grass said first: "People nowadays don't pay attention to environmental protection. There is rubbish everywhere around us. It stinks! " "The tree said," Yes, where the sewage in the factory flows, it will suffer. It will flow into the river and all the fish in the river will die. "Grass added," It's not too late to mend, but the guests don't pay attention to it. "The tree said," Don't talk about all people. Some pupils attach great importance to environmental protection. They will spend time picking up garbage when they have time, but some adults will litter. " Grass said, "then we have to thank those pupils!" " The tree said, "destroying the forest is complete suicide." Even primary school students know this truth, why don't adults know it? " It is not good for them to do so. If trees are cut down too much, it will rain heavily and cause mudslides. ""there will be. You kill people at will, flow into the river, make it burst and change its course. These are the reasons why people don't protect the environment and cut down trees indiscriminately. Human beings are greedy for petty gain, but forget that this will cause natural disasters. "

"Although we can't tell people that this is not good, I believe that those primary school students will definitely manage the environment in an orderly way when they grow up, let the vegetation grow freely and let the river flow smoothly."

The grass said, "I am looking forward to this day."

The earth is our home for human survival. However, in recent years, our living environment has been continuously destroyed and the global temperature has risen. White garbage and water resources are polluted. Faced with so many problems in ............................................................................................................................................., I asked myself: Are we just going to sit back and watch?

In China, such scenes can be seen everywhere. In the street, there are always people spitting and littering; In the tree, you can clearly see that someone is painting and changing; Even, in some places, some people will defecate everywhere. These people simply don't have the self-control and morality as a person, but we are still helpless in the face of these problems and can only watch them do these things. As a primary school student, the future of the country, I believe that environmental protection should start from itself, from the dribs and drabs of life. For example, no littering, no spitting, collecting waste paper and so on. We should abide by the daily behavior norms of primary school students and jointly protect our homes.

Students, let's protect the environment together!

Energy Saving and Emission Reduction, Strive to Create Brilliance

"The progress, stagnation or decline of a civilization, or the increase, leveling or decrease of per capita energy consumption; Or the efficiency of energy development and utilization is improved, leveled or decreased; Or the impact of energy development and utilization on the environment and society is reduced, leveled or increased. " Highlighting the practical significance of energy conservation and emission reduction as an important means to promote scientific development and an important standard to test whether Scientific Outlook on Development has implemented it shows the importance and urgency of this work in the future.

"China's energy problem has reached the point where it will affect the whole body. Without reform, there is no way out and it is difficult to compromise. "

In the early 1990s, China was still self-sufficient in energy, because it had its own coal, its own oil fields, rich hydropower resources and bioenergy. At present, the general view is that the rise in oil prices will not affect the overall steady growth of China's economy. However, if there is no long-term concern, there will be future trouble. At present, China's energy consumption per unit GDP is 70% higher than the world average, its heating energy consumption per unit building area is 2-3 times higher than that of developed countries, its dependence on foreign countries is close to 50%, and its oil import is second only to that of the United States. According to the research report of the National Research Center, by 2020, the lower limit of China's oil demand will be 450 million tons, and the upper limit will be 66,543.8+tons, while the domestic output is expected to be only/kloc-0.8 billion to 200 million tons, which means that China's dependence on overseas resources will reach at least 55%, which is roughly equivalent to the current 58% dependence of the United States on foreign countries. Obviously, China's energy and some mineral resources are highly dependent on foreign countries, which seriously restricts the sustainable development of China's economy. However, we have not done enough in the education of basic national conditions. Not long ago, a Japanese scholar asked college students, graduate students and staff in China about "the ranking of China's total resources and per capita possession in the world", but no one could answer accurately. But even primary school students can give accurate answers when asked such a situation in Japan. This situation is thought-provoking, and it also highlights the urgency and importance of strengthening basic national conditions education and making energy-saving awareness deeply rooted in people's hearts.

In addition to the grim situation of "energy saving", the completion of this important task of "emission reduction" is not optimistic. In fact, according to the current economic growth inertia, China's demand for fossil energy will continue to grow, and it is difficult for enterprises or institutions to reduce emissions immediately. Under the background of economic globalization, China's existing development model has been unable to cope with the pressure of carbon dioxide emission reduction. Therefore, in order to establish a good national image and corporate brand, we must be brave enough to undertake the corresponding binding responsibility of emission reduction, which inevitably requires changing the mode of economic development, optimizing the industrial structure, strictly controlling the energy use and pollution emissions of enterprises, accelerating the popularization and application of advanced and applicable technologies, and eliminating backward production capacity.

At present, the situation of energy conservation and emission reduction is still very grim, mainly because the scientific cadre performance evaluation system has not been fully established and the scientific enterprise development concept has not been truly established. In some places, the assessment of cadres still regards GDP growth as a hard task, and energy conservation and emission reduction as a soft indicator; Some enterprises still only pay attention to the acquisition of economic benefits, but ignore the control of environmental costs and resource and energy losses. Based on this, the Central Economic Work Conference proposed to realize the development of "good and fast, giving priority to good words", which not only put forward higher requirements for energy conservation and emission reduction, but also provided greater impetus for us to break through the bottleneck of energy and environment. Without energy conservation and emission reduction, it is impossible to achieve scientific development.

As a developing country, China can't blindly follow the western industrialized countries to use fossil energy to develop its industry, let alone blindly accelerate the increase of private cars ... Otherwise, China will be hit by the energy crisis in advance! Only by implementing clean production, vigorously advocating civilized consumption and taking the road of sustainable development is our inevitable choice.

The public is both a consumer and a producer and manager of the environment. Achieving the goal of sustainable development means a profound change, a change in people's world outlook, values and morality, and a change in people's behavior. Whether the public is willing to accept and actively participate is a necessary condition for implementing these changes. If 65.438+300 million people in China use less disposable wooden chopsticks, a piece of white paper and a New Year card, what a huge number the whole country adds up to, which is equivalent to how many forests have been protected! If all the lighting lamps in the country are replaced by energy-saving lamps, the country can save about 60 billion kwh of electricity a year, and to produce so much electricity, it needs 30 billion kilograms of coal. To promote energy conservation and emission reduction, only the active promotion and guidance of the government, the implementation of the majority of enterprises is not enough, but also the support and participation of all sectors of society, especially all urban and rural residents!

Let each of our citizens take action, starting from me, starting from scratch, starting from now, starting from the side, making their own contribution to the realization of the national energy conservation and emission reduction goals, and creating a more economical, cleaner and more civilized and sustainable life.
