Second grade environmental diary

Environmental protection is everyone's responsibility, without exception. The second grade environmental diary I compiled below is welcome for reference!

Environmental diary (1): protecting the environment is not a temporary thing, and we need to persist in it every day and put it into practice anytime and anywhere. As long as each of us takes action, we will certainly be able to save our home-the earth.

Save electricity, protect resources and reduce pollution.

Electricity is something that every primary school student comes into contact with every day, that is, something that we can't live without every day, but it is amazing at the moment. Therefore, every move when using electricity should start with saving.

In China, power generation mainly depends on burning coal, and the coal on the earth is limited. According to the current consumption rate, the global coal will be consumed within 250 years. After that, we will have no coal for our future generations.

Saving electricity means saving coal, which directly helps to reduce air pollution. Because acid rain is caused by coal burning, it can strongly corrode buildings, acidify soil and water, lead to reduced grain production and death of plants, fish and shrimp. According to calculation, the annual economic losses caused by acid rain in southwest and south China alone amount to 654.38+0.4 billion yuan.

Saving electricity can slow down global warming. Because of the excessive carbon dioxide emitted by coal burning, it blocks the heat from the ground from radiating to the outside of the sky like a hood, resulting in the greenhouse effect. If the earth's temperature rises, it will cause drought or flood and melt icebergs. If all the icebergs on the earth melt, countries and islands with lower altitudes will disappear.

Living today, we will definitely enter the next century. Many of them are vulnerable to global warming. Germany 192 school. 50,000 children vowed to reduce the harmful gases that cause greenhouse effect in their communities by 65,438+00%. They put on energy-saving lamps, refused to use air conditioners, put down their cars and chose bicycles. After seven months of hard work, they achieved their goal.

In a blink of an eye, we are about to enter the beautiful June, which is a great opportunity to plant trees and green the country. In order to create a good green home and protect the ecological environment, I suggest that students:

Love nature, love flowers and trees, protect animals, and carry out tree planting and green protection activities.

Promote environmental protection with your heart and bring environmental awareness into thousands of households.

Diary of environmental protection (2): The earth is our home, just like our mother, it brings us resources and conditions for survival. We are the masters of the earth, and we should protect it as well as ourselves.

Who doesn't want to make their home more perfect and beautiful? However, with the development of science and technology, there are more and more kinds of domestic garbage, most of which will cause environmental pollution. For example, our commonly used batteries will cause great environmental pollution if they are not handled properly after use. According to research, a section of waste button cell can make 600,000 liters of water undrinkable. If everyone throws away a waste battery, then water will become a luxury at that time.

So, in order to protect the environment, please classify the garbage.

On June 2008 1, China implemented the "plastic restriction order", saving 37 million barrels of oil every year. Plastic bags, this kind of thing is common for ordinary families, but it is, but do you understand that plastic bags are a major factor in polluting the environment? Plastic bags are made of petroleum, which not only consumes a lot of resources, but also takes 500 years to decompose naturally.

Therefore, to protect the environment, please reduce the use of plastic bags.

The recent global climate change conference in Copenhagen once again sounded the alarm. Although it didn't achieve the expected results in the end, if it didn't, it would be useless to hold a meeting. At the meeting, it was said that the global average temperature is rising gradually and most icebergs have begun to melt. If this goes on, the world will be submerged. At the moment, the global average temperature is higher than before 1. 1℃, although it is only a small 1. 1℃, but this is the "global average temperature"! If the global average temperature rises by 4℃, the temperature in the Arctic and Antarctic will rise by 16℃. By then, trees can also be seen in the North Pole and South Pole. Think about it, what will the world be like at that time?

In fact, the chief culprit of these disasters is us humans. According to research, electrical appliances or other things we use every day will emit too much carbon dioxide, which is one of the main factors to raise the temperature. If you reduce the use of electrical appliances, carbon dioxide emissions will also decrease. Automobile exhaust also contains too much carbon dioxide, so parents should be reminded at any time to take the subway or bus as little as possible when going to work or going out, and drive less private cars, which can reduce the emission of too much carbon dioxide.

Therefore, in order to protect the environment, please reduce the use of electrical appliances and drive less private cars to work or travel.

As the masters of society, it is our bounden duty and obligation to improve the global environment. At this time, if everyone in the world is environmentally friendly every day, we can create a brand-new beautiful world!

Diary of environmental protection (3): There is only one earth for human beings, which is the natural resource on which human beings depend. If people want to live a happy and perfect life, they must consciously protect the natural environment and care for the earth.

However, in recent years, the environment of the earth is getting worse and worse: global warming, frequent disastrous weather such as hurricanes and rainstorms, and frequent infectious diseases such as SARS and bird flu have brought serious threats and inconveniences to human life and work. These are the results of people constantly "hurting" the earth. Large areas of forests have been cut down, and at this time, green hills have been dug up, beautiful grasslands have become deserts, and clear rivers have become turbid. With fewer trees, bare mountains, bare grasslands and dark water, people's living environment becomes worse, the air they breathe is worse, and the living environment is "occupied" by many harmful things. Viruses will take the opportunity to enter people's bodies, and we humans will suffer from some terrible diseases.

A few days ago, I saw a cartoon in the newspaper: a man was sitting at the top of a tree, cutting branches where he was sitting. "Hum, that's funny." Some people may think so. Don't you think this is just a funny cartoon? Isn't that sarcasm? Don't you realize that it is warning us that human beings are unconsciously hurting themselves while destroying the environment?

When you are walking in the street, what will you do if you want to spit? If you choose to throw up on the ground, have you ever thought that you are hurting yourself? A mouthful of sputum contains a lot of germs, which will multiply and infect as soon as the sun shines. Similarly, when you cut down a tree, when you dig up a meadow, when you pour mud into the river, don't you think it is destroying the environment and "hurting" yourself?

As the saying goes, "predecessors planted trees, and later generations enjoyed the cool." Our predecessors gave us large areas of forests and green spaces, but what did we leave for future generations? It's a bare desert, and it's a dense forest. You must choose a dense forest. What is there to hesitate about? Let's protect the environment, care for the environment, green the environment, improve our living environment and create a perfect future!

Diary of Environmental Protection (IV): Looking around, there are only uneven land, and a large area of forest has been cut down, which has become a wood product in people's lives. People just make groups of animals homeless and rush to other places for their own self-interest. This is not a false fantasy, this is a bloody fact.

Once upon a time, a large number of animals and plants in the world were extinct, and many animals and plants were on the verge of extinction. That's why. This is all because of human deforestation and destruction of the ecological environment, which is the fundamental reason.

Land resource is one of the three major geological resources (mineral resources, water resources and land resources), and it is the most basic resource and labor object of human production activities. The degree of land use by human beings reflects the development of human etiquette, but it also causes direct damage to land resources, mainly manifested in soil erosion, land desertification, secondary salinization of land and soil pollution caused by unreasonable farming, among which soil erosion is particularly serious, which is another serious crisis facing the world today. At this time, it is estimated that the global surface soil loss of cultivated land is about 23 billion tons/year.

Some people think that acid rain is a silent crisis, the most serious environmental threat that has ever attacked us, and an invisible enemy. This is not an alarmist. With the increase of industrialization and energy consumption, acid emissions are also increasing. They enter the air and form acid rain after a series of actions.

Although red tide has existed since ancient times, with the rapid development of industrial and agricultural production, water pollution is becoming more and more serious. Since 1933 was first reported in China, 1994 * * has had 194 large-scale red tides, of which there were only four before the 1960s and 157 after the 1960s. Oil pollution is very harmful to water quality and aquatic organisms. The oil floating on the water surface can quickly spread to form an oil film, which prevents the water surface from contacting with the air and reduces the dissolved oxygen in the water. At this time, the oil contains polycyclic aromatic hydrocarbons carcinogens, which can be enriched by aquatic organisms and endanger human health. Sulfur dioxide is mainly produced by the combustion of sulfur-containing substances such as coal and fuel oil, followed by natural sources, such as volcanic eruptions and forest fires. Sulfur dioxide has a strong stimulating effect on human conjunctiva and upper respiratory mucosa, which can damage the ventilator pipeline and cause bronchitis, pneumonia, even pulmonary edema and respiratory paralysis. Short-term exposure to sulfur dioxide concentration is 0. The mortality rate of the elderly or chronic patients in 5 mg/m3 air increased, and the concentration was higher than 0. 25 mg/m3 will worsen the condition of patients with respiratory diseases. Long-term exposure concentration is 0. Respiratory diseases increased in people with 1 mg/m3 air. In addition, sulfur dioxide is easy to cause corrosion, peeling, fading and damage to metal materials, construction, cotton and chemical fiber fabrics, leather paper and other products. It can also make plant leaves yellow or even die.

Protecting the environment is everyone's responsibility.

Environmental Diary (5): The earth is a world with many resources. With the progress of our human science and technology, we have used a lot of resources, but if we humans don't know how to save resources, we will reduce the resources of the earth ... "Nature sometimes breeds things, land makes money limited, but people's desires are infinite." Bai Juyi, a poet in the Tang Dynasty, still has his own interests. The era we live in is facing serious problems such as lack of resources and environmental pollution. For the sustainable development of our living environment and economy and society, conservation and environmental protection are imminent. Every one of us holds precious "resources" and the "lifeline" of the development of the Chinese nation. The invention of paper is a great contribution to human politeness. At present, there are about 500 kinds of paper produced in China. At present, we have the necessary stationery-paper. Paper can be seen everywhere: textbooks, exercise books, draft books, etc. Many, many. But that is, many students waste paper and throw it around on campus. Let's act together to save paper.

Saving paper means planting trees.

From study to life, we can't live without paper, and the raw material of paper making is mainly the fiber of plants such as bark, but because people cut it blindly. There are fewer and fewer trees now, so we should save paper. It is everyone's responsibility to start from the little things around us.

The concept of "saving paper" seems a bit far away from saving water and electricity for us. Few people know what is the direct relationship between saving paper and protecting the ecological environment. Each of us uses paper every day, using different types of paper. Have you counted them? How many sheets of paper do you use every day? How much paper do you need a week? How many sheets of paper do you need a month or even a year? The result is amazing. Where does a piece of paper come from? Paper is transformed from a tree. It often takes decades for a tree to be used by human beings. Humans are ruthless. With the sound of chainsaws, trees that have grown for decades fall to the ground. Wood was transported to the paper mill and turned into pieces of paper. Paper has brought convenience to human beings, but at the same time it has also brought great influence to forests.

Trees can be used not only to make paper, but also to bring wood. A large area of forest can conserve water, prevent water loss and purify the air. If there are no trees, there will be no oxygen, and there will be no place for human beings to live. The harm of forest disappearance is great: the Loess Plateau was originally a forest, lush and endless, with green waves rippling. However, due to people's destruction, the Loess Plateau has really become a plateau with only loess at the moment, and the earth has taken off its coat and exposed its yellow skin, which is very sad. Moreover, because there are no trees and too much soil is lost, the sediment concentration of the Yellow River is extremely high. How can human beings be indifferent to such great harm? Afforestation is imminent.

Forests are factories that make oxygen. Forests can absorb harmful substances, maintain soil and water, and conserve water. The canopy is like an open umbrella, which can intercept 10~20% rainfall. The water storage capacity of 50,000 mu of forest is equivalent to a small reservoir of 6,543.8+0,000 cubic meters.

March 12 every year is "Arbor Day". On this day, many people take tools to plant trees. At present, the forest coverage rate in China has increased. This is the result of human introspection, which is gratifying. However, although the forest coverage rate has increased, it is still very low. Therefore, afforestation is an arduous task, which is the eternal task of mankind. It's summer. Although the best period of planting trees has passed, we can sow the seeds of "saving paper" in our hearts and plant trees for afforestation. By the next spring, these trees will sprout and grow tall. We can go outdoors with tools, sow the seeds of trees on the earth, take good care of them and make the motherland full of green!

Environmental diary (6): The earth is our home, that is, our mother. We rely on it and explore it. How beautiful this blue planet is, but we must understand that there is only one earth!

Unfortunately, many people turn a blind eye to this simple truth and continue to do whatever they want, regardless of the safety of the earth's homeland. Qu, an environmental scientist, once said: "Only change can save the fate of mankind, and only change can make our descendants survive." One of the "changes" is environmental protection. That's right, so now many people are holding slogans and shouting empty slogans in the street, but they don't see much action. Will the pollution get better? Don't!

You see, the rivers in our city are black and smelly; Long queues of cars emit too much exhaust gas; A piece of green land has become a "stone forest"; The crisp birdsong disappeared without a trace. In this way, China will continue to be short of water, the air will become more and more turbid, and 10% of bird species will disappear in this century. The above things, we humans are the culprit!

Everyone knows that trees can absorb carbon dioxide, release oxygen and purify the air, which is a necessary condition for our human survival. However, some people cut down trees for money, which leads to excessive soil erosion, serious damage to the earth's vegetation, and desertification of oases and cities, threatening our human survival. As for the disposable chopsticks we usually use, it consumes dozens of acres of forest every day. In the eyes of those people, trees seem to have no value except for furniture and building materials. Does anyone not understand what trees mean to us? Our living area is already very small. If we go on like this, we may even lose our only land. In addition, the Yellow River, our mother river, has become one of the most polluted rivers in China in recent years. We can't watch the Yellow River dry up from our hands, so many environmentalists have studied plans to control the pollution of the Yellow River and tried to improve its water quality. However, without our participation, the Yellow River, the cradle of our life, will run dry and die.

If we destroy the environment again without restraint, we will naturally be punished. Those catastrophic floods claimed countless lives, and due to the greenhouse effect, glaciers in Antarctica and the Arctic melted, resulting in rising water levels and seawater flooding coastal areas, which caused great economic losses. Isn't this the best proof?

My hometown Guangning relies on Zhuhai eco-tourism to develop its economy. Now, the environment of some bamboo forests is so chaotic that people complain. Eco-tourism in Zhuhai is the foundation of our development in Guangning. If the roots are destroyed, how can we grow lush branches and leaves and produce beautiful flowers?

Let's be kind to human beings and nature! I wonder if you have read the article 100 things you can do to protect the environment. In fact, there are many things we can do. For example, plant a pot of flowers and a tree on Arbor Day; Protecting wild animals means ecological balance; Cherish water resources and don't dump garbage into the river; To be a little environmental guardian, we should use every green anniversary to publicize environmental awareness, so that green mountains always exist, green water always flows, and the soil always smells ... This is what we can do. Why don't we want to practice it?

At present, the ecological environment of the earth is deteriorating day by day, and the environmental alarm has sounded. Let's join the ranks of environmental protection, create a perfect future where man and nature live in harmony, and let man and nature live endlessly.

Environmental Diary (7): A long time ago, the stars in the sky lit up the beautiful blue earth like small lights.

I don't know that the earth has turned for billions of years, and one day an animal like a monkey appeared. At first, they were friendly to all kinds of creatures on the earth. But after that, their intelligence developed and their greed grew. They eat whatever they want, wear whatever they want, and plunder everywhere with open hands.

They chopped up Uncle Lin's hair and beard to make their favorite greeting cards, disposable chopsticks and paper cups, and often dug up their favorite oil, coal, various minerals and precious stones in Uncle Earth's stomach.

In this way, they pulled out all the hair on the earth, leaving a bare world. They also invented something called air conditioning. They drilled one big hole after another in Aunt Sky's skirt, broke the mysterious palace of the sun, and poured a knife-like beam onto the earth. They throw things into the sea every day, and Mother Ocean's children are poisoned by those dirty things.

"We can't wait for death like this, we must find a way to save ourselves." Uncle Forest said to Aunt Sky.

"But it is. What shall we do?" Mother Ocean frowned and couldn't think of any good ideas at the moment.

"Let's go and see the great and omnipotent goddess of nature. She must find a way. " Aunt Sky put forward her recommendation.

They came to the goddess of nature and poured out their sufferings in tears. "We must destroy them, otherwise, we will not survive!" Uncle Forest gritted his teeth, clenched his fists and said angrily.

"At the moment, it's still a little premature to destroy them. You can give them some color to see see first, and show them a yellow card warning. If they don't repent, it's not too late to destroy them. " Mother Nature's eyes sparkled with kindness.

"Well, let them know what we can do!" Mother Ocean and Aunt Sky said together.

Mother Ocean caught fire first, and the typhoon 10 lifted the roof and blew all the crops away. Aunt Sky's tears merged into a downpour, and the flood surged, and the earth soon became a Wang Yang. Those tall trees and buildings were submerged in the blink of an eye. The running cattle and sheep were washed away by the flood in the blink of an eye.

Flies and mosquitoes are everywhere, happily spreading the plague. All kinds of bacteria come out, and compete to show their abilities, to see who is the most destructive and who is the most destructive!

From the hole in Aunt Sky's skirt, there is a terrible light, which contains toxins. When standing on the skin, the skin will rot.

Uncle forest said to the children, "our hair has been pulled out, turning the earth into a desert, so that they can never see flowers and grasslands again."

The air is dirty, the water is dirty, fish die in groups, eagles disappear into the sky, and only groups of animals like monkeys are left on the bare land-monkeys!

So, one day, they asked themselves, "How can we live at this moment?"
