Composition of forest encounter

People think of the forest when the wind and sand are blowing all over the sky, and people think of the forest when the soil and water are lost, because the forest is our irreplaceable home. The following is the composition of meeting the forest, welcome to read!

There used to be many forests on the earth, but most of them were destroyed to varying degrees due to human deforestation.

Due to soil erosion and the destruction of vegetation, many originally fertile lands have become deserts. Just like the Yellow River, because the vegetation in the place where the Yellow River flows is destroyed, the soil is washed into the river by rain, turning the river into turbid yellow, hence the name of the Yellow River.

Forest is the strong backing to maintain the ecological balance of the natural environment, which can resist the attack of sandstorm and reduce noise. After heavy rain, the forest can absorb rainwater well and reduce the possibility of flooding. In the event of an earthquake, mudslides are prone to occur in mountainous areas. However, if the vegetation is dense in the mountainous area, their roots can firmly penetrate into the cracks in the stones, fix the soil and stones, and reduce the harm to human beings.

Forests are also oxygen processing plants. In the sun, trees can carry out photosynthesis, absorb carbon dioxide and release oxygen.

Forests have many benefits. There are many small animals living in the forest, such as squirrels, sika deer and antelopes. The forest is also the place where we can't live without medicinal materials. With them, we can form our beautiful ecological home.

The extensive destruction of forests is an inestimable loss for us human beings. The world we live in is chaotic and noisy. Air pollution and noise pollution seriously affect our life and health. The incidence of human diseases rises sharply every year, which cannot be said to have nothing to do with the reduction of forest distribution area. Therefore, we humans should wake up one day earlier to protect the forest. In fact, we are protecting our home! I hope those short-sighted people don't give up everyone for their small families. In the long run, the world will really be in danger. The forest is the protector of our lives, and it needs all of us to protect it.

Chapter two: The experience of forest composition Last week, the math teacher told me the lesson "The harm of disposable chopsticks", which made me remember it vividly. When I got home, I also participated in the online "Save the Forest, Chopsticks Action!" Let me introduce the harm of disposable chopsticks to you.

Disposable chopsticks do great harm to the human body, of which the biggest harm is three: the first is to damage the respiratory function. Disposable chopsticks should be fumigated with sulfur in the production process, so when heated during use, sulfur dioxide will be released and the respiratory mucosa will be eroded. The second is to damage the digestive function. Disposable chopsticks are bleached with hydrogen peroxide in the production process. Hydrogen peroxide is very corrosive, which has corrosive effects on oral cavity, esophagus and even stomach. The use of talcum powder in the grinding process can eliminate impurity, which will make people suffer from gallstones. The third is bacterial infection. Sterilized disposable chopsticks have a shelf life of up to four months. After the shelf life, it may bring Staphylococcus aureus, Escherichia coli and hepatitis virus.

China consumes 45 billion pairs of disposable chopsticks every year, and every 5,000 pairs of wooden disposable chopsticks consume a poplar that has been growing for 30 years. Every disposable wooden chopstick produced in China consumes more than 65,438,000 mu of forest, totaling 36,000 A Mu years. China disposable chopsticks are exported to Japan. If an adult tree can produce 10,000 pairs of chopsticks, then China needs at least 2.5 million trees to export more than 20 billion pairs of disposable chopsticks to Japan, and tens of thousands of square kilometers of forests need to be cut down. Different from the "thinning" method adopted by Japan, most of China's forest harvesting adopts the "one-day illumination" method, which is destructive to China's forest resources. The original renewable forest resources have become disposable resources, which is a great waste of forestry resources in China. The results of the sixth national forest resources inventory released in 20XX show that the national forest coverage rate is 18. 2 1%, and the per capita forest area is only 0. 08 hectares, ranking 134 in China. In order to produce disposable chopsticks, less trees and more carbon dioxide will have a greenhouse effect.

From now on, we should take chopsticks to the restaurant without disposable chopsticks, so as to achieve the "action of eating with chopsticks". Let's all take part in the "Action to Protect Forests and Chopsticks"!

Start with me and plant all kinds of trees to make China a shady country!

Forests are the source of life. Without forests, we would have no home, no fire and no cooked food. If there were no forests, our breath could not be oxygen. Without oxygen, we will die of lack of oxygen. So trees are essential in our life. We can't live without trees.

Trees can absorb carbon dioxide and produce oxygen, so that living things can survive better. If trees are cut down wantonly, birds will be homeless. If deforestation fails to maintain ecological balance, it will become a desert. We need trees in our life. Trees are essential resources for human beings. It is ok to cut down trees reasonably. In order to express our apologies to the trees, we designated March 14 as Arbor Day.

There are many pests, so every animal has natural enemies, and pests also have natural enemies. That's a woodpecker. If humans chop down trees indiscriminately, woodpeckers will not have enough to eat, so birds will have no home. In order to prevent pests from eating trees, trees can be made to grow better and contribute to human beings, while human beings cut trees indiscriminately, which brings harm to trees. There was once a story: a man came to a big forest with a cigarette in his mouth to cut down trees. When he was about to chop, a woodpecker came and pecked his head, which showed that there were worms in this man's brain. After reading this story, we should protect trees and prevent humans from damaging the environment. Some factories discharge some sewage into the river for convenience, which causes the pollution of the mother river. Now there are more and more sandstorms in Beijing, our capital. If the environment is not protected, our capital will become a desert.

So we must plant all kinds of trees, so as not to hurt ourselves and let us become good friends of trees.

I saw a cartoon today, which said: a lush forest, but the trees in that part of the forest have exposed bare stumps, and the other half of the trees are still thriving. Not only do they know that they will be cut off like them when they grow up. At this moment, a man came up with a cigarette in his mouth and said, "There must be bugs in this piece of wood." Then he picked up a big axe and cut it at a tree. Then a woodpecker flew in, landed on the man's neck and said, "There must be bugs in this tree." Peck the man's head from time to time.

This cartoon reminds me of a story: the mystery of the disappearance of forest kingdom. It tells a story: Once upon a time, there was a kingdom called "Forest Kingdom". Under the care of an old king, everything in the forest is so harmonious. There are vibrant plants here, which can stop the wind and sand, adjust the temperature of nature and balance the ecology. However, in order to live in a tall building and show his "cleverness", the new straw bag king cut down trees at an alarming rate. Finally, the straw bag king was helpless in the face of the revenge of nature's "rain demon", "sand demon" and "hail demon", but he still stubbornly refused to plant saplings, so the yellow sand swallowed up the whole palace with this stupid king and turned the whole king into a desert.

After reading this short story, I was deeply inspired. We should not show our "cleverness" in order to ignore the ecological balance, which will eventually lead to the demise of this king. Forests are indispensable friends for creatures living on the earth. It is the "lung of the earth", which can absorb carbon dioxide and produce oxygen necessary for human survival. She is "the great natural reservoir of the earth". People who cut down trees are hateful. They cut down trees for their own benefit and destroy the ecological balance. We should cherish forest resources, environment and the earth.

One night, I had a wonderful dream that I walked into the big forest in my dream.

"ah! The scenery in the big forest is really beautiful! " As soon as I entered the big forest, I couldn't help admiring it, like a beautiful landscape painting. The green grass is full of colorful flowers, including white, yellow, red, pink and purple ... red is like fire, yellow is like gold, white is like jade, pink is like chardonnay, butterflies are dancing among the flowers, and bees are collecting honey, which is very beautiful. Rows of tall trees are lush, like handfuls of green velvet umbrellas. Birds are chirping, streams are gurgling, a group of insects are giving a concert, crickets are playing the violin happily, Jin Lingzi is singing with a microphone, and grasshoppers are beating drums, like melodious songs. The little monkey is swinging on the tree, and the little animals are playing happily.

I am enjoying the beautiful scenery of the forest. Suddenly, a serious lion came to me, and I was afraid. The lion said to the animal policeman behind him, "Look, this is a man, arrest him for me!" " The animal police handcuffed me and took me to the forest court.

Soon, Judge Tiger announced the trial. First, a deer came crying and said, "You took my sister away and put her in the zoo. I lost my sister, and there is no one to play with me anymore! " Then a panicked bird said weakly, "Humans often hit us with slingshots, leaving me nowhere to hide and displaced." "Human beings are really hateful." Animals scrambled to tell their misfortunes, louder and louder, and their anger almost shattered the roof of the court. Finally, Judge Tiger decided to sentence me to life imprisonment. I cried and said, "No! Don't! "

At this time, my mother's familiar voice came: "Get up quickly, the sun is shining on your ass!" " "I was awakened. I got up and sat on the bed, thinking of those little animals who lost their loved ones, and I was very sad. I think it would be great if humans and animals live in harmony, love each other, become good friends and enjoy the same blue sky and the same earth!

Chapter 6: Forests are closely related to human beings, close partners of human beings and an important part of the global ecosystem. If there is no forest, most of the life on land will be extinct, and most of the water will flow into the ocean; Oxygen in the atmosphere will decrease and carbon dioxide will increase; The temperature will rise obviously, and floods and droughts will occur frequently. Forests can also improve air quality, reduce sediment loss, conserve water, reduce sandstorm hazards, reduce noise pollution, beautify the natural environment and so on.

However, forest fire is the most dangerous enemy and the most terrible disaster in forestry. This will bring devastating consequences to the forest. Forest fires will not only burn patches of forest, harm animals in the forest, but also reduce the regeneration ability of the forest-a fire may take decades or even hundreds of years to restore the forest. It will also cause soil impoverishment, destroy the function of forest to conserve water, and even lead to imbalance of ecological environment. Despite the rapid development of science in the world today, human beings have not made great progress in putting out forest fires.

Forest fire refers to the behavior that forest fire is out of human control, spreads and expands freely in woodland, and brings certain harm and loss to forest, forest ecosystem and human beings. Forest fire is a sudden, destructive and difficult natural disaster.

Many people don't know the present situation of forests. Look-"countless tractors and bulldozers rumble and countless trees fall to the ground. Animals were scared away and pieces of land were bulldozed. Then flames, smoke, birds whine, monkeys howl ... "

Is this human behavior? Love the forest! Come on, let's go!

Deforestation is a foolish act of human beings. Don't do such a harmful thing. We must protect the existing forest resources!

Beware of forest fires from happening again!

Some people say, "Without forests, there would be no human beings". This sentence is not exaggerated. Forest is the basis of food production safety, and it is very important to protect farmland and preserve nature!

Ecological balance and beautifying the environment are very important. Among all ethnic groups in China, the Dai people's awareness of ecological life and ecological protection is probably the most conscious and prominent. In the eyes of the Dai people: without forest, water, farmland, farmland and food, people can't live; The relationship between man and ecology should be the order of forest, water, land, grain and man. Therefore, whenever the Dai people go to a new place, they must swear to care for the forest as much as their own lives.

In the forest, the relationship between animals and plants is also very close. Some insects will invade trees, and birds will devour these insects, so that the whole forest world will be balanced. Lush forests not only provide a lot of food for animals, but also provide a place to live. In turn, many animals, especially birds, protect green forests.

There are many pests in the forest, which threaten the survival and development of plants. Some pests are particularly rampant and can eat large areas of trees and leaves. For example, Dendrolimus punctatus is the enemy of the forest. When the situation is serious, it is necessary to control pests manually. However, chemicals commonly used in artificial pest control have great side effects. The best way is to create good conditions for birds, the natural enemies of pests, to control pests with birds. The familiar woodpecker is a good forest doctor. Birds are not only the protectors of the forest, but also our friends. An owl. It can take back a ton of food from mice for human beings in one summer. Therefore, we must protect human beings and protect forests; Protect the forest and protect the birds. We can make many wooden boxes and hang them on trees to provide birds with superior habitats, so that they can have children and survive and develop better. In this way, it is not only beneficial to their growth and reproduction, but also can protect the forest.

Only by protecting forests and birds can human beings really protect themselves. Students, you must be willing to build a warm home for birds, right? Then act quickly!

Chapter 8: Encounter of Forest Composition Spring is over and lush summer has arrived. Blue sky, dense forest, everything is so bright. Milky white fog shrouded the lush forest, and the "shy" little girl loomed from the clouds. The forest under the sunshine is like an endless green ocean.

The forest is the home of animals and their paradise. There is a touching story about this forest! Let me tell you something!

In a season of lush leaves and drizzle. Larks compete and sing on ancient trees, little monkeys swing on trees, pandas play "slides" in the forest ... All animals are doing what they like. At that time, the forest was their paradise and their home. However, one day, something unfortunate happened. Because some people scribble on trees for memory; Others only care about immediate interests and cut down trees quickly. The birds have no place to nest, and they all fly away. Animals have no homes and run around. What is even more frightening is that one day, a big storm was warned, and there was no forest to stop the sandstorm, which blew down all the houses in the village not far from the forest, killing and injuring many people. The animals are heartbroken.

Under the leadership of uncle elephant, the animals organized themselves and wanted to rebuild the forest themselves. Birds brought some tree species, moles were busy digging holes, and monkeys kept carrying water. After a while, the green saplings came out. The spirit of unity and tenacity of animals touched people. Everyone took action, fertilizing, weeding and caring. A few years later, the tree grew new branches and lush green leaves. How beautiful! A new forest is unfolding before people. Since then, no one has come to destroy the forest. People live in peace with animals, and everyone lives a happy life.

Chapter 9: The experience of forest fire is the first lighting tool for human beings. In ancient times, cooking, boiling water and heating were all inseparable from fire. Or was regarded as a "hero" in ancient times. They will also think of many great men according to the different shapes of the fire when it burns. However, today, if we use it or are not careful, it may cause irreparable disasters and losses to the forest.

Humans can't live without oxygen. Oxygen comes from green forests. If forests don't exist, humans will have to carry oxygen tanks on their backs. How troublesome it is! Therefore, protecting our green forest is our best choice. If we don't protect the forest, we have no choice.

As the saying goes, "A little star can destroy a hundred forests. This sentence is true in life. /kloc-from 0/980 to 2006, there were about 200 serious fires, 800 small and medium-sized fires, and 200,000 hectares of forest were destroyed. According to the survey, 99.9% of the fires are man-made. In the man-made fire, 98% is caused by a match or a cigarette butt, and the rest is caused by a small Mars that is not handled properly after the fire. If someone steps on cigarette butts, sparks, etc. Over time, these tragic gambling events will not happen! How much loss can that avoid?

So according to these, only by protecting the forest and using fire carefully can we avoid forest fires and learn some fire fighting knowledge. If the forest is on fire, you can put out the fire yourself. If you can't put out the fire, call for help If you don't have a telephone, shout to put out the fire to avoid forest fire.

Forests are for the benefit of mankind. We should protect the forest and call on the villagers around us to tell them not to cut down trees indiscriminately and use fire carefully. This is our duty.

Our happy life now is given by green! We bite the hand that feeds us. We should work together to protect our green forest and make it better for our future generations! Protecting the forest is everyone's responsibility.
