I think everyone knows that people nowadays have become "drivers", even my family is no exception. However, because of this, vehicles consume a lot of energy and emit a lot of exhaust gas every day.
Because of this, our living environment is being destroyed day by day and getting worse and worse. ...
Therefore, we all advocate "green travel" to protect our "kind and kind grandfather of the earth"-take an extra bus to prevent him from getting weaker every day; Drive less to stop him sighing all day; Riding a bicycle, don't let him hang a drip in the ward; You can also walk to keep him from vomiting and diarrhea; You can also take the subway to stop him from dragging his tired figure all the time. ...
In addition, the exhaust gas from cars is not only harmful to beautiful flowers and trees, but also harmful to our health: I am no exception, so I always insist on "green travel".
According to the statistics of the scientist's uncle, Beijing is now equivalent to a "waste gas city", and the waste gas is like a dirty cauldron, covering the originally desirable Beijing! There are many towering buildings in Beijing, which block the air flow, reduce the wind speed and increase the vortex, so the pollutants discharged into the air by the city are not easy to spread; Coupled with the dustpan-shaped geographical features of Beijing surrounded by mountains on three sides, it is easy to form an inversion temperature over Beijing, that is, the ground temperature is much lower than above! In this way, the up-and-down convection of air is destroyed, and the air containing pollutants on the ground cannot be exchanged with the air above in time, which further aggravates the air pollution in Beijing. Therefore, when the wind is light, it is like building a dirty cauldron over Beijing!
This dangerous situation has sounded an extremely huge alarm for people. Don't drive any more, don't emit any exhaust gas, and don't let the kind-hearted grandfather Earth suffer any harm that he shouldn't have suffered. ...
Here, I silently wish our kind and kind grandfather, the weak body, get better day by day. ...
Green Travel Speech 2 During the National Day holiday, my parents and I discussed how to play. In the end, everyone unanimously decided to have a green trip-hiking Yushan. The next morning, we put on sports clothes and sneakers, prepared a big pot of water and set off with food.
We went to Yushan along LAM Raymond Road and Yushan North Road. There are not many people on the sidewalk, but the cars in the middle of the road are constantly flowing. At every traffic light at the intersection, cars lined up. The driver honked his horn impatiently and urged the car in front. The air is filled with the pungent smell of car waste, and the black tail gas is filled in the air, muddling the clear blue sky. At the foot of Yushan Mountain, the parking lot is full, but people waiting for parking are still lined up. We crossed the queue and headed straight for the mountain road.
There are many people climbing mountains on foot. Everyone is talking and laughing in small groups, enjoying the scenery on the mountain while walking. The road is getting steeper and steeper, my legs and feet are getting sour, my breathing is getting faster and faster, my heart is beating faster and faster, and my head is starting to sweat. Stop, find a roadside stone to sit down, have a drink and catch your breath. The cool mountain breeze blew head-on, and it suddenly cooled a lot. Looking around the mountain, the maple leaves in the mountain are red and rustled by the autumn wind; Wild chrysanthemums on the roadside are in full bloom, purple, gold and white, and bees are flying around them; Birds are twittering in the Woods, flying from tree to tree, as if playing hide and seek; Pomegranate trees in the roadside farmhouse yard are covered with heavy fruits, bending the branches. Seeing this, we are happy and refreshed, stand up and continue to set off.
After a long journey, we finally reached the top of Yushan Mountain. The sky here is particularly blue, and white clouds float on it like white sheep. The endless tea trees are neatly trimmed, and a burst of osmanthus fragrance combined with fresh air is refreshing. We lament the beauty of nature and realize the great significance of low-carbon life travel. We call on everyone to make our mountains greener, our water greener, our flowers more beautiful and our cities more harmonious. From now on, please restrain yourself, get off the bus and have a fashionable and green trip, which not only protects the environment, but also exercises our bodies and cultivates our sentiments.
Hello, I'm Liang Yuxin from Class 4, Grade 8. The topic of my speech today is "Green Travel, Environmental Protection and Energy Saving".
Speaking of green travel, environmental protection and energy saving, I think everyone is familiar with it. The meaning of these eight words is very important, which is related to our personal physical and mental health, to the harmonious development of society and even to the bright future of mankind.
With the development of science and technology and the improvement of living standards, people's lives are getting richer and richer, and all kinds of private cars have become an indispensable part of modern life. Nowadays, people seldom walk, don't want to ride bicycles, and don't want to squeeze buses. More and more people like to drive private cars, which leads to more and more crowded roads. Automobile exhaust is more and more harmful to air quality and human living environment. The endless traffic in the city emits a lot of exhaust gas, such as nitrogen oxides, carbon monoxide, carbon dioxide and hydrocarbons. The sharp increase of these waste gases will seriously lead to the deterioration of the natural environment and do great harm to our health. We can't deny that private cars bring convenience to personal travel, but they have an unshirkable responsibility for environmental deterioration.
Therefore, we should establish the life concept of "green travel, environmental protection and energy saving", use green travel modes such as walking, cycling, taking bus or subway as much as possible, and drive fewer private cars, which can not only reduce automobile exhaust emissions, but also be conducive to environmental protection and energy saving. Walking or cycling can achieve fitness effect and relieve the increasing traffic pressure in the city.
In order to better improve the urban environment, reduce waste gas and noise pollution, and let us breathe fresher air, I propose to actively promote the concept of green travel, environmental protection and energy saving to family and friends, establish a civilized awareness of environmental protection and energy saving, and participate in the activities of "green travel, environmental protection and energy saving".
Dear students, green travel starts with one step. Let us use practical actions to support green travel, environmental protection and energy conservation, so that green transportation will gradually become our travel habits, making the city less polluted and more fresh; Make roads less congested and smoother; Let's have fewer children and more diseases, and realize the dream of an ecologically livable city as soon as possible!
Thank you, my speech is over.
Speech on Green Travel 4 Dear teachers and students:
Low-carbon life is a very environmentally friendly and civilized lifestyle. Saving water, electricity, fuel and solar terms can help us turn a low-carbon life into reality.
At present, our country has made a public commitment to the world emission reduction target, and decided to reduce greenhouse gas emissions by 40%-45% by 20xx compared with 20xx. The low-carbon era has arrived as scheduled and is changing our lives. Low carbon is around us. In summer, when we use the air conditioner at home, don't turn it on for a long time. After a few hours, turn off the electric fan and turn it on again. This can save electricity by 50%; When putting food into the refrigerator, the amount of food should be 80% of the volume, and the plastic box should be filled with water to make ice before putting it into the refrigerator, which can prolong the downtime, reduce the start-up time and save electricity. When food is processed by microwave oven, it is best to add a layer of non-toxic plastic film or cover it, so that the moisture in the processed food is not easy to evaporate, the food tastes good and saves electricity. When driving, try to avoid sudden speed change, choose appropriate gears, avoid low-speed driving, change the oil regularly, keep the tire pressure appropriate, and turn on the air conditioner less. When the computer is not used for a short time, enabling sleep mode can reduce energy consumption to below 50%; Turn off unused programs and peripherals, such as speakers and printers; Do not let the hard disk, floppy disk and CD work at the same time; Reduce the brightness of the display appropriately.
Usually, you can achieve low carbon by diligent hands and brains. There are many discarded boxes in ordinary families, such as soap boxes, toothpaste boxes and milk boxes. In fact, as long as they are cut slightly, they can be used conveniently, such as making a storage box, in which items such as tea bags and cosmetics can be placed; You can also make a beautiful desk lamp with instant noodle boxes, cans and yogurt bottles. Dried tea residue, dried in the sun as a tea pillow, is comfortable and can improve sleep.
In addition, replacing ordinary light bulbs with energy-saving lamps, walking, riding a bike or taking a bus as far as possible, and unplugging electrical appliances casually are all seemingly casual things that contribute to carbon reduction.
We should start with such small things as saving electricity, water, carbon, oil and solar terms. Low-carbon life is a green lifestyle we want to build. As long as we act, we can approach the low-carbon life and reach the standard of low-carbon life. In short, low-carbon life is not only to protect the environment, but also to save yourself.
Then, for our primary school students, are there any other good ways to reduce consumption and low carbon? Let's take a look at my suggestion.
Double-sided use of paper saves paper;
Do not use disposable chopsticks and disposable lunch boxes;
Do not use disposable plastic bags;
Reduce food waste;
Turn off the lights, turn off the tap.
Use handkerchiefs instead of paper towels.
Our earth needs our common care. Let's start from the small things around us, cherish resources, reduce energy consumption and make our life better.
Green Travel Speech 5 Dear teachers and students:
Hello everyone! The topic of my speech is "protecting the environment and traveling green". Whenever environmental problems are mentioned, it is a commonplace topic. We have made a lot of efforts in environmental protection and achieved initial results, but the great cause of environmental protection still has a long way to go. Almost when we were very young, we heard the saying that it is everyone's responsibility to protect the environment. Along the way, people around us are committed to environmental protection in our country, but the problem of environmental pollution still exists now.
I think no one doesn't want to breathe fresh air, no one doesn't want to see the sky bluer and the water clearer, and no one doesn't want to see the clean and healthy environment we live in every day. However, plastic garbage bags that are discarded at will can still be seen everywhere in our lives. Perhaps the most intuitive feeling for each of us is the rather poor air quality. The "unknown objects" such as smog, smoke and particles are still with us, perhaps in the breathing room, we inhaled a lot of pollutants. At present, our environmental pollution mainly includes water pollution, soil pollution and air pollution. Today we will discuss air pollution in particular. As we all know, serious air pollution will lead to respiratory diseases, and worse, it will lay a curse in the body. There are many reasons for air pollution, and we have taken relevant rescue measures many times. For example, we should severely resist some sewage companies, pay attention to the transformation of discharged gases, and try our best to ensure that things entering the air are pollution-free.
Nowadays, one of the most useful countermeasures is "green travel". With the improvement of China's economic level, people's living standards are getting better and better, and cars have almost become a necessary travel tool for every household. Wider and wider roads symbolize the speed of economic development in our city, but at the same time, the appearance of more and more vehicles also profoundly affects our living environment. Automobile exhaust emission is also one of the important factors that cause air pollution. Now people are used to driving when they go out. No matter what you do, no matter the distance, you are used to driving. Vehicles are not only our means of transportation, but even our "legs". According to the fact that every household travels twice a day, the daily automobile exhaust emissions of so many families in the world will be a terrible figure, that is, these exhaust gases continue to pollute our living environment, and the air quality is getting worse and worse, which will harm ourselves over time. Therefore, we must always pay attention to "green travel" and reduce environmental pollution.
Green represents hope and rebirth. In the face of environmental problems, we should give the greatest hope and make the greatest efforts to make the environment "reborn" and give all of us a green and quiet living place. Green travel is actually very simple. We should always pay attention to establishing the concept of green travel, especially for children, and tell them the significance of green travel from an early age. We can also set an example for them and enjoy riding bicycles by public transport, such as buses, subways and the popular * * *. Of course, when choosing vehicles and fuels, we should try to choose new energy vehicles and vehicles with high energy-saving and emission-reduction performance. Sometimes some short-distance routes can be reached by walking or cycling. , so as to minimize the utilization rate of cars.
Students, green travel is none of our business. We need to work together. Every family can work together to make the earth green! Protect the environment and travel green. From now on, we must work hard to stick to it! Thank you, my speech is over!
Speaking of green travel, people always have a wrong idea: only driving is the best and most comfortable. This is the psychology of enjoyment.
I think cycling is the best choice.
First of all, there are more and more people driving now. Although the road has been widened, it is still crowded. Some people are unhappy when they are blocked, and they swear at the horn, which is very uncivilized. Some are in a hurry to go to work, others are in a hurry to do something urgent, but what can they do? Wait, you look blank. I can't help it But the problem of cycling no longer exists, the road is unimpeded, and the mood is like a bird flying, so a happy day begins.
Secondly, although driving looks ostentatious, it costs real money to maintain. You can buy a bicycle every time you spend, plus one year of insurance, maintenance, cleaning, fines and so on. how much is it? Cycling is free, so it saves money.
Also, cycling is not only convenient, but also can exercise. I couldn't run long distances before. Since I learned to ride a bike, I have gone out for a ride every night. In less than a month, I successfully took it down and ran a long distance. My mother has been losing weight, and it has no effect. I suggested that she stop driving and go to work by bike. I didn't expect the weight loss effect to be super ideal, and my physique was enhanced. I advise those who are worried about losing weight to start cycling if they want to lose weight.
Riding a bike has so many benefits, let's start riding together!
If the 20th century is a century of war, then 2 1 century is a brand-new century. You see, cars that used to be affordable only to the rich have entered thousands of households. We can often see such a phenomenon: the streets are full of traffic, especially during the peak hours of going to school, leaving school and commuting, cars are driving one after another. Sitting in a comfortable car, you see so many cars emitting exhaust gas at the same time. Have you considered environmental pollution? Yes, cars are coming and going in the street, and clouds of smoke come out from behind the cars, which pollutes the environment.
So, how harmful is the tail gas emitted by cars to human beings?
According to relevant data, the composition of automobile exhaust is quite complex, with more than 100 substances, and the pollutants discharged are mainly carbon monoxide, hydrocarbons, hydrocarbons, nitrogen oxides, particulate matter and lead compounds. Although the proportion of these pollutants in automobile exhaust is not large, they are the chief culprit of polluting the environment and endangering human health. The most direct consequences are global warming and carcinogens. It can be seen that the emission treatment of automobile exhaust is not a trivial matter.
First of all, we should reduce the utilization rate of cars, take more public transport, be nearby, and even choose to walk. Walking not only exercises the body, but also reduces the exhaust emissions, killing two birds with one stone.
Secondly, we can also carpool. Take the last parent-child activity as an example. Except for a few students who choose public transportation, most of our classes drive cars, but if two families drive one car to the farm, they can drive 20 fewer cars, which can reduce a lot of exhaust emissions. For example, parents can take turns to pick up and drop off students living in the same community or nearby, which saves time and effort and reduces exhaust emissions, killing two birds with one stone.
There are electric cars now, but charging is a bit inconvenient. I hope that in the near future, solar cars can be invented to replace the cars that burn gasoline now. By then, the cars we drive will no longer emit tail gas that pollutes the environment. Solar energy is an inexhaustible green energy source and can also save the use of other energy sources.
Green travel, start with me! If everyone becomes a little guardian of environmental protection, then our only home will become more beautiful!
Green Travel Speech 8 Recently, the sky is getting darker and darker, the air is getting worse and worse, and there is smog everywhere.
The students in our class are very concerned about air pollution, so they held a seminar on this topic. The seminar began and everyone was in full swing. Some students say how to reduce air pollution, some students say that air pollution is harmful to us, and some students say why there is air pollution. In short, each has its own reasons.
Beibei said excitedly, "The air pollution is too serious now. If you want to travel green, you must! "
"Yes, all of us must travel green, drive less and take more buses. Walk more and ride a bike. This will reduce smog! " The rumble meaningfully supplemented Beibei.
"How slow you walk! It' s hot to squeeze the bus! " Yao Ming retorted. "Hum, what's wrong with driving? Fast, cool and convenient. Reducing smog has nothing to do with driving! "
You said thoughtfully, "Obviously, this is not right. Green travel is everyone's business, not one's. So be sure to live a low-carbon life and drive less. "
Li Dongdong should know: "There are many advantages to driving less. For example, it will not emit too much waste gas and pollute the environment. Therefore, you should drive less, cycling will not emit exhaust gas, and you should ride more bicycles. "
"Oh, I see. We want to travel green and live a low-carbon life, right? " Clearly said.
"Yes, yes." Everyone says "green travel, low-carbon life."
Yes, everyone should be environmentally friendly, drive less, ride more bicycles and walk more. Come on, let's try to breathe fresh air!
Around us, "car" is a common word. Cars are closely related to our lives. It can improve our travel speed and bring convenience to our life, but its negative effects should not be underestimated.
With the development of science and technology, cars are also making progress, and the development of cars has also caused excessive energy consumption and air pollution. In life, we see the phenomenon of car congestion every day. Maybe when we keep using private cars, it has a great influence on our air. Now our sky is gray, and the usual smog weather has quietly entered our lives, and the smog has made our air turbid.
Then what can we do to restore our past blue sky and white clouds? We can take fewer private cars and walk more, which not only exercises our bodies, but also reduces exhaust emissions. Why not? You can also ride bicycles and electric cars, which is also good for reducing obesity.
I remember once again, I watched TV, and many people lost their precious lives because of drunk driving. Cars can be abandoned, but life is only once, and cars have many negative effects on us, so we should put an end to the situation of using cars in large quantities.
Here, I propose:
First, be a pioneer in green travel. If your family wants to buy a car, please buy a car with low displacement, low fuel consumption and low pollution.
Second, to be a practitioner of green travel, we use the "135" plan: 1 km within walking, 3 km within cycling and 5 km within public transportation. If you have to travel by car, you should drive in an environmentally friendly and civilized way.
Third, be an advocate of green travel and pass on low-carbon life and green travel to classmates, teachers and parents.
For the beauty and health of our home, let's join hands from now on, start from ourselves, start from the little things around us, and travel green together to make our home greener, smoother, more civilized, bluer, healthier and happier!
"Green Travel, Low Carbon and Environmental Protection" starts from me!
