Afforestation has many benefits! First, afforestation can prevent wind and fix sand. Every time the wind blows and the sand flies, people who have to go out are like fish struggling in stormy waves. People who follow the trend can't help but fly forward, their legs go forward against the wind and their bodies fall back, which makes people miserable.
In order to resist the attack of sandstorm, we must plant trees vigorously to prevent wind and fix sand. Secondly, afforestation can provide many valuable resources.
Wood is the main product of forest, which can be used for building houses, building bridges and making paper. Wood can also be used as tools, furniture, handicrafts and other daily necessities.
There are edible aspects, such as sweet and sour fruits, butter tea, high-grade medicinal materials and so on. In short, it played a great role. Third, afforestation can eliminate air pollution and beautify the environment.
These "environmental guards" such as dust and carbon dioxide we absorb every day have played an inestimable role in purifying the air and ensuring people's physical and mental health. In addition, afforestation can prevent soil erosion, reduce noise, protect ecological balance, and provide people with an ideal place for study, work, entertainment and life.
Forests are indeed people's loyal friends, but now, forests are disappearing rapidly, which has become a major concern for us. So afforestation has become a top priority! We want to plant trees, and we want to green the motherland.
2. How to write a composition about afforestation Spring has come and Arbor Day has arrived. Three young pioneers from Sakura Primary School are going to plant trees.
One morning on the weekend, Young Pioneers Bing Bing, A Hong and Mix had put props on their bodies. On the way, the three young pioneers all had excited and proud expressions on their faces, as if the saplings they planted had grown into towering trees, which could purify the air, beautify the environment, absorb carbon dioxide and exhale oxygen ... Soon, they came to Xuanwu Lake, where they were going to plant saplings.
Bingbing dug two big holes with a shovel. A Hong carefully put two saplings in the hole for fear of damaging one of them. Xiaoxiao got some fertilizer and sprinkled it in the pit. Finally, Bingbing "filled in" the pit with a shovel, and propped it up with her feet.
Xiaoxiao scooped up half the water in a bucket in the lake and poured it into the soil. The young trees began to grow. Every Sunday after that, they will send someone to water and fertilize the young trees.
Three generations of gentlemen. Several years have passed, and the trees planted by Bing Bing, A Hong and Xiao Xiao have grown into towering trees.
3. Composition of Afforestation I like cultivation since I was a child and have a special affection for trees. I am glad to see my growth year after year.
Now I can't hold the acacia tree planted more than 20 years ago. In recent years, I have rarely returned to my hometown because of my work, and occasionally I feel that the trees have grown bigger and thicker. Looking up at the high supply and protection of Gaoshutou, I not only have many ideas. Trees not only bring me material rewards, but also prove my contribution. I don't plant many trees, but I love and want to plant trees. I don't know if the tree that I can't forget the most is growing well now. It was in 2000 when my workmates and friends at Bayi Steel planted elms at the foot of Tianshan Mountain. I have been thinking that the elm forest in the distance will be remembered every year on Arbor Day.
Greening the motherland refers to carrying out afforestation activities and covering the whole country with green plants. Afforestation has many benefits!

We want to plant trees, and we want to green the motherland!
The annual Arbor Day is coming, and we begin to protect trees and forests. More than half of people think that forests and trees should be protected only on Arbor Day, but my opinion is just the opposite. We should always protect forests and trees, not just on Arbor Day.
Hundreds of millions of years ago, when the earth was owned by animals, plants were lush, vibrant and green. However, after the emergence of human beings with much higher IQ than other animals, plants decreased sharply as if they were enchanted. That's because humans cut down trees to build houses. For commercial needs, some people cut down a lot of trees to make room for buildings. It is precisely because many people cut down forests and trees without authorization that nature is destroyed.
Cutting down trees has many disadvantages. Everyone knows that trees can recycle carbon dioxide. If a large number of trees are cut down, the number of trees will decrease sharply, and the carbon dioxide we breathe out cannot be recycled. Dense trees can stop sandstorms. Two years ago, Beijing was hit by a sandstorm, and the whole city was covered with sand, which was also caused by poor tree protection.
Everyone knows about the two bay cities in the Central Plains! In the past, it was in rags. The tiles of those bungalows are one hole in the east and one hole in the west. The doors are made of wooden boards, and the streets are full of rubbish and dirty. Now apartments and buildings have been built in two bays in the Central Plains. The river is crystal clear, and the willows along the river sway gently with the breeze. This is why people realize the importance of respecting nature and protecting the environment.
I hope everyone can protect the forest, protect the trees and add a little green to the life of the city!
The earth is our home and the mother of mankind. We rely on it and explore it. How beautiful this blue planet is, but you know, there is only one earth! Regrettably, 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 environmentalist, once said: "Only change can save the fate of mankind, and only change can make our descendants survive." The word "change" means environmental protection. That's right, so now many people are holding slogans and shouting empty slogans in the street. Don't! You see, the rivers in our city are black and smelly; Long queues of cars emit a lot of exhaust gas; A piece of green land has become a "stone forest"; The crisp birdsong disappeared without a trace. If this continues, China will continue to lack water resources, the air will become more and more turbid, and 65,438+00% of bird species will disappear in this century. 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 has caused excessive soil erosion, seriously damaged the vegetation of the earth, the desertification of oases and cities, and threatened our human survival. In the eyes of those people, the disposable chopsticks we usually use consume dozens of acres of forest every day. Trees seem to have no value except 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 riverbed and sediment content of the Yellow River, our mother river, has been increasing in recent years, making it one of the most polluted rivers in China. We can't watch the Yellow River dry up from our hands. Therefore, many environmentalists have studied the scheme to control the pollution of the Yellow River in an attempt to improve the water quality of the Yellow River. However, without our participation, the Yellow River, the cradle of our life, will run dry and die. If we destroy the environment without restraint, we will naturally be punished. Those catastrophic floods claimed countless lives. Due to the greenhouse effect, glaciers in the Antarctic and the Arctic melted, leading to rising water levels. Seawater flooded the coastal areas, causing serious economic losses. Isn't this the best proof that my hometown Guangning relies on bamboo eco-tourism to develop its economy? Now the environment of some bamboo forests is very bad, which makes people complain. Bamboo eco-tourism 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, we can do many things, such as planting a pot of flowers and a tree on Arbor Day. Protecting wild animals is the balance of ecology; Cherish water resources and don't dump garbage into the river; Being a little environmental guardian, using every green anniversary to publicize environmental awareness, so that green mountains are always there, green water is always flowing, and the soil is always fragrant ... these are all things we can do. Why don't we want to practice? Now, the ecological environment of the earth is getting worse and worse, and the alarm of environmental protection has sounded. Let's join the ranks of environmental protection, in order to create a bright future in which man and nature live in harmony, and let man and nature continue to live endlessly. Chapter 2: Everyone has the responsibility to look ahead and protect the environment. There are only uneven land, and a large area of forest has been cut down and turned into wooden products in people's lives. People only seek their own interests. 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 others were on the verge of extinction. 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 utilization by human beings reflects the development of human civilization, but it also causes direct damage to land resources. This is mainly manifested in soil pollution caused by soil erosion, land desertification, secondary salinization of land and unreasonable reclamation, among which soil erosion is particularly serious and is another serious crisis facing the world today. 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 and the most serious environmental threat that has ever hit us. It is 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, there have been 194 large-scale red tides up to1994 *, of which only four occurred before 1960s, and 157 occurred after 1990. Oil pollution has caused great harm to water quality and aquatic organisms. The oil floating on the water surface will quickly spread and form an oil film, which hinders the contact between the water surface and the air. It can be enriched by aquatic organisms and endanger human health. Sulfur dioxide is mainly produced by burning sulfur-containing substances such as coal and fuel oil, and secondly comes from nature, such as volcanic eruption and forest fire. Sulfur dioxide has a strong * * effect on human conjunctiva and upper respiratory mucosa, which can damage ventilator pipes and cause bronchitis and pneumonia. Even pulmonary edema and respiratory paralysis. The elderly or chronic patients exposed to sulfur dioxide with a short-term concentration of 0.5 mg/m3 will increase the mortality rate, and the concentration is higher than 0.25 mg/m3, which may aggravate the condition of patients with respiratory diseases. People who have been exposed to air with a concentration of 0. 1 mg/m3 for a long time have more respiratory diseases. In addition, sulfur dioxide is easy to cause corrosion, peeling, fading and damage to metal materials, buildings, 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. Chapter 3: Protecting the environment means protecting the future earth, which is our home, just like our mother.
Today, my sister, two friends and I came to the park to plant trees.
Let's put the saplings in carefully first, and everyone is busy. My sister is holding the sapling, and I step on the soil, cultivate some soil, and then step on the soil again and again with my feet.
At this time, my two friends came back with a bucket of water, and they poured the water evenly under the tree. Everyone is not afraid of hardship and fatigue, and they all work very hard. There were bursts of laughter from time to time.
We are all sweaty, but I still don't want to rest. No matter how hard and tired you are, you must stick to it.
I use a ruler to look from left to right, so that the saplings become a straight line. Then I heard my sister shout, "Great! Great! Small saplings can take root and sprout in the soil! " I asked my sister, "Is it true?" My sister said, "Yes!" When two friends saw it, they jumped three feet like victorious soldiers.
Suddenly, the breeze blew, and the sapling bent down and bowed to me, my sister and my friends: "Thank you! Dear friends, thank you for your cultivation. " I slowly poured water into the roots, and the water immediately penetrated into the soil.
The sapling drank enough water and nodded and smiled frequently, as if to say, "friends, watch, I will grow into a tree that covers the sun and let you play in the cool." The afterglow of the sunset sprinkled on the earth, and we packed up our tools and reluctantly left the saplings.
Planting trees today is really interesting.
