Environmental protection ingredients 1
Environmental pollution has many consequences, among which smog is the most profound one, which has affected our daily life and travel activities.
So do you know what smog is? Haze is mainly composed of nitrogen oxides, sulfur dioxide and inhalable particles. The abbreviation of particulate matter is PM, and PM2. 5 indicates that the diameter is less than or equal to 2. 5 micron pollutant particles are not only a pollutant, but also carriers of many toxic substances such as heavy metals and polycyclic aromatic hydrocarbons.
What harm does smog do to us? Because the diameter of particles in smog is generally 2. Below 5 microns, it can be directly inhaled into human respiratory tract and lungs, causing respiratory diseases and lung diseases, and even inducing lung cancer in severe cases, which is extremely harmful to human body. At the same time, due to the low fog weather, the oxygen content in the air drops, and people will feel chest tightness, shortness of breath and headache in this environment. It can be seen that smog will have a serious impact on human survival and health.
Knowing the harm of smog to human body, how should we prevent it? Do less outdoor sports in foggy days, pay attention to cleanliness, don't open windows for ventilation, drink more water and eat more fruits. We should wear masks to travel when we go out. In order to protect the environment, we should drive less, plant more trees, use clean energy and protect the environment, starting from me!
There are many ways to protect the environment, such as garbage sorting, which can maximize the use of garbage resources, reduce the amount of garbage disposal, reduce land occupation, turn waste into treasure, save energy, reduce environmental pollution and improve the quality of living environment. Convenient for others, but also convenient for yourself!
There is also the protection of wild animals. As we all know, eating wild animals is easy to infect diseases. This year's novel "Coronavirus" is a typical case, which makes us spend a long winter vacation and realize that "seeing you again in winter is summer". Therefore, protecting wild animals not only maintains the ecological balance, but also protects ourselves and our common home.
Protecting the environment is everyone's responsibility. Green lifestyle is what we need to advocate and implement, and each of us needs to take care of our living environment and our mother earth. Let's put "environmental protection, start with me" into the little things around us and make our country more beautiful. Let's take action and work together for the future of our motherland. Protecting the environment is urgent!
Environmental protection composition II
With the progress of science and technology and the development of economy, people's living standards are getting higher and higher, but environmental pollution is also increasing: cars emit exhaust gas; Factories pollute water sources; Trees are cut down at will ... Have people who only pursue economic interests ever thought about the serious consequences and heavy costs that these actions have long been used to destroying the environment ...
Now cigarette butts in factories often emit some exhaust gas, and cars in the streets also emit exhaust gas. Because these gases contain a lot of toxic and harmful substances, so there will be so many haze weather. This phenomenon is not only common in large and medium-sized cities like Beijing, Shanghai and Guangzhou, but also in towns and villages. So, what can be done to avoid these phenomena? Of course there is. If the factory chooses to use those environmentally friendly combustion materials, or add filtration systems and other treatment methods when discharging waste gas. People travel: when the road is far, you can choose to take the bus; When the road is not too far, you can choose to ride a bike; You can choose to go when the road is near. These methods not only protect the environment, but also exercise the body.
At present, because factories discharge a lot of sewage, people dump garbage into rivers, lakes and oceans at will, the water quality is destroyed and most of our drinking water is polluted. If every factory has a sewage filtration system, every community has garbage bins everywhere, and every region has a unified garbage storage station and garbage treatment plant, such pollution problems can also be solved.
Now, in order to increase the amount of cultivated land and get more food, farmers use trees for heating and cooking in rural houses, so they cut down a lot of trees, disposable chopsticks are widely used in urban catering industry, and high-grade solid wood furniture is used by urban and rural residents, which is one of the reasons for the large number of trees being cut down. Trees are cut down and there is no forest, so natural disasters, such as sandstorms, deserts and mudslides, will attack us ... If farmers stop destroying forests and open up wasteland but return farmland to forests, biogas, gas and coal will be used in farm houses. For heating and cooking, city restaurants also use sterilized chopsticks. When people cut down trees, they will plant many trees and cut down many kinds less. In this way, some natural disasters such as sandstorms and mudslides can be avoided.
Not only air and water, but also the grain, vegetables, fruits, meat, eggs and milk we eat now are artificially "polluted": the grain is genetically modified, and crops use a lot of preservatives such as fertilizers, pesticides, ripening agents, contraceptives and formaldehyde ... livestock are also fed with some fast-growing and oxytocin-inducing feeds, so meat, eggs and milk are also "polluted". ...
I heard from my grandfather and my parents that when they were young, the sky was blue and they didn't know what smog was. The water is clear, and fish and shrimp swim in the river; Crops are healthy and farmyard manure is used; Moreover, every spring and autumn, everyone will organize or even spontaneously build water conservancy projects and plant trees, and even primary school students will plant trees under the leadership of teachers.
But now the environmental pollution is too serious, it is difficult to find the past, and it has reached the point where it can't be cured. As Stephen Chow said in The Mermaid, "If there is not even a drop of clean water and a breath of fresh air in this world, no amount of money will be a dead end." Indeed, due to environmental pollution, people are faced with the threat of serious diseases and death every day, so what's the use of making more money and creating more social wealth? Life can buy money, but money cannot buy life. Let's keep the world vigilant! Eliminate environmental pollution, protect the earth, protect our homeland and protect ourselves!
Composition 3 on protecting the environment
I want to breathe fresh air under the blue sky, fish want to swim in clear water, and birds want to sing euphemistic songs in green. We all want to live in a clean, beautiful and comfortable environment. Protecting the environment is my wish.
I grew up in a small county. According to their parents, when they were young, they drank water from the well. There are many small fish in the clear river. My friends often go to the river to catch fish, dig wild vegetables and cut grass together. Every family doesn't have a car. When they go out to visit relatives, they either ride bicycles or walk. They buy vegetables with baskets and eat authentic crops. At that time, the sky was blue, the clouds were white, the mountains were green and the water was clear.
In recent years, with the development of economy, people's lives have been greatly improved, but also brought about environmental damage. The wastewater discharged from the factory pollutes the water environment; Exhaust gas from factories and many cars pollutes the atmospheric environment of PM2. 5. These once unfamiliar words have become a topic that people often care about; Plastic bags instead of vegetable baskets have caused "white pollution"; Deforestation causes soil erosion; Abuse of pesticides threatens food safety. A series of behaviors that destroy the environment have seriously affected our study and life. Let's take action to protect the environment, starting from me and starting now.
As students, we should take good care of flowers and trees, do not trample on the lawn and pick flowers indiscriminately; No littering, classified by recyclable and non-recyclable; Save water, use more water, and form a good habit of turning off the tap at will; Save electricity, turn off the lights, turn on the air conditioner less, and support green lighting; Do green travel, try to take buses, ride bicycles and drive less cars; Bring your own shopping bag and lunch box, and pack items in detachable bags; Protect animals and plants, refuse to eat wild animals, refuse to use wildlife supplies, and make good friends with animals and plants; Persuade patiently when you see acts that damage the environment, publicize the obligation to protect the environment, and let people realize the importance of protecting the environment.
"Lucid waters and lush mountains are invaluable assets". The earth is our home. We should protect the ecological environment of the earth as we protect our eyes, so that it can benefit mankind from generation to generation.
Arbor Day arrived on the 3rd 12. Let's plant saplings ourselves, and also plant the wish to protect the environment. "It takes ten years to plant trees, but it takes a hundred years to cultivate people", so that the environmental protection baton can be passed down from generation to generation.
Composition 4 on protecting the environment
People often say: "Don't let the last drop of water on the earth turn into human tears!" " "This sentence embodies the voice of many volunteers!
The earth is our common home. The respectable Mother Earth has given us many things: rich mineral resources, precious water resources, various animal resources and plant resources ... Without Mother Earth, there would be no human beings and such a warm home.
The earth has given us so much, but human beings treat our earth like this:
Deforestation. With the harsh roar of the chainsaw, the trees groaned and tried to resist, but the trees could not resist the arrogant woodcutter after all. Finally, it landed on the land where it was attached with a thud, giving the last sigh of its life. ...
Destroy water resources. A clean stream was singing happily and ran out of his hometown-the mountain forest, hoping to have a look at the outside world. When it came to the metropolis excitedly, it regretted it: people always poured dirty sewage into its clean body, and its fragile body was full of garbage and scars left by garbage. Over time, it is no longer that clear and lovely stream, but a dirty and smelly gutter. To this end, it stays in Lacrimosa all day. ...
Overexploitation of mineral resources. Once the mineral resources are exploited too much and the formation time can't keep up with the mining speed, it will only accelerate the depletion of mineral resources on the earth. Pits left by mining resources are likely to lead to heavy metal pollution and ecological disasters.
According to statistics, there are1300 million people in the world who do not need clean water; More than 6.5 million tons of garbage are dumped into the ocean every year, and fishery resources are on the verge of exhaustion; Every year,170,000 hectares of forest disappear; More than 100 species are extinct every day ... In Shanxi, the mined-out area formed by coal mining is equivalent to 1/8 of the total area of Shanxi!
I was shocked to see this shocking data. The earth was riddled with "children" and devastated.
People, the earth is our home. Without the earth, we would not have a comfortable life now. However, we don't cherish what the earth has given us. Deforestation, over-hunting, over-exploitation, even if it will make our pockets swell, have we ever thought about the earth? Have you thought about the fate of our descendants? With the deterioration of our artificial environment, our descendants will either evolve into "monsters" who have to resist the deteriorating environment, or human beings will perish directly. As the textbook says, "what comes to the earth will eventually come to the children on the earth."
So, let's start from ourselves: when shopping, replace disposable shopping bags with cloth bags and baskets; Replace disposable chopsticks with stainless steel chopsticks; No littering; Turn off the tap at will; When traveling, you can walk or ride a bike for a short distance. If you want to travel, you can take a bus ... to give Mother Earth blue sky and vast land. Protect the environment, start with me!
Composition 5 on protecting the environment
The happiness of the sky lies in its blue skirt; The happiness of sunshine lies in its dazzling brilliance like crystal; The happiness of the earth lies in the colorful life; People's happiness is to have a beautiful earth; In my eyes, the earth is a kind mother who holds us in her arms.
However, sometimes Mother Earth gets angry: rivers dry up, plants wither, the earth cracks, forests catch fire ... After these things happen, people get busy. They planted many trees, cleaned the streets and alleys, and Mother Earth began to become gentle again.
As we all know, the earth is the cradle of life and our home. Mother Earth has given us a warm home. If we leave her, we can't live for a minute. Therefore, we should care for the environment and repay Mother Earth.
As we all know, no littering, no spitting, no cutting down trees, no trampling on lawns, no picking flowers … However, some people deliberately litter everywhere. I remember once, I saw a little boy throw an empty jar into the river. I immediately went up to him and said, "We can't litter and pollute the environment. We should be small environmental guards." After listening to my words, he bowed his head in shame.
Water is the source of life and the most important part of energy needed by our human body. It can not only quench thirst, but also nourish plants. Water has brought us a beautiful living environment with lush trees, birds and flowers, picturesque scenery and peace. So, let's protect the water source together!
Plants are also one of our most needed friends, because they can purify the air, absorb the nitrogen dioxide we exhale and create new oxygen for us to breathe. Without fresh air, human beings will not survive. If there are no plants to help us resist sandstorms, Mother Earth, on which we live, will become a desert ... They are like "greenguard", guarding us all the time.
Sowing green is to save yourself. If you want to breathe fresh air and drink pure water, you must protect and care for the environment.
Although the air in the country is good and the scenery is good, the tall buildings in the city are beautiful and neat. But people's awareness of environmental protection is very poor. The factories in this city always emit black smoke, which seriously pollutes the air and water. The clear and bright stream became dirty and smelly. It is unreasonable for us to pollute the water source. When plants are destroyed, we lose fresh air, water sources are destroyed, our drinking water will be affected and our lives will be threatened.
Nature is our flesh and blood relatives. Therefore, protecting the environment means protecting ourselves. Let's do more things to make Mother Earth happy, protect the fragile and great mother, plant trees and make her healthy!
