# Keynote Speech on Environmental Protection (Selected Articles 1)#

Teachers and students: Good morning, everyone!

The topic of my speech under the national flag today is: practicing environmental protection under the dome.

Recently, some aunts in Xicheng continued to dance square dance in foggy days, causing cough and asthma attacks. First of all, I hope my aunts will recover soon. At the same time, I am also surprised that the square dance that human beings can't stop was defeated by smog! Where is the smog? So powerful!

Haze is actually a combination of fog and haze. Fog is water vapor condensate composed of small water droplets or ice crystals suspended in the atmosphere, not pollution. Haze refers to the turbidity caused by a large number of particles such as smoke and dust suspended in the air, which will cause air pollution, and its core substance is dust particles. Fog and haze often accompany each other and sometimes can be transformed into each other, so they are collectively called "haze weather".

Haze will endanger traffic safety, ecological environment and human health. When smog occurs, bacteria and viruses are often carried in the air, which easily leads to the spread of infectious diseases and the occurrence of various diseases. Speaking of foggy weather in winter, if we encounter serious air pollution, it may form poisonous fog, which seriously threatens people's health. If inhaled for a long time, serious people will die.

In order to resist smog, various methods to prevent smog are circulating on the Internet. For example, grapefruit peel is used as an anti-smog mask, and even cigarette filters are inserted in the nostrils to prevent smog, not to mention whether these methods are useful. Such a "heavy taste" is not affordable for everyone. So, what can be done to effectively prevent smog? Don't open the window in foggy days, wait for the smog to disappear, and then open the window for air after the sun rises. Go out as little as possible, cancel morning exercises, wear a mask when you go out, and wash exposed skin immediately after you come back. Usually drink more water, eat more fresh fruits and vegetables, eat less irritating food, and eat more foods such as pears, oranges and lilies that have lung moistening effects. A classmate said to me, "Teacher Han, in order to prevent smog, I will not drink coke in the future, but drink rock sugar and Sydney drinks every day." In fact, water is a drink! Vitamin D supplementation can promote calcium supplementation. Not basking in the sun in foggy days will affect the body's production of vitamin D. Here I also want to talk about professional throat protection. Professional throat users, such as teachers, are more likely to have throat problems in foggy days. I suggest that I use my voice as little as possible in foggy days. I'm learning oral skills recently. To keep the indoor temperature and humidity, you can drink some chrysanthemum and wolfberry tea. Besides self-protection, what can we do for the air?

Next Monday, we will celebrate World Meteorological Day on March 23rd. The theme of this year is-Climate knowledge supports climate action. Teachers and students, think about how long we haven't seen the blue sky. Let's take Meteorological Day as an opportunity to take active actions and use what we have learned to support the prevention and control of smog. Under the dome, practicing environmental protection, "Wuxi Blue" will stay in the sky forever one day.

Thank you!

# Keynote Speech on Environmental Protection (Excerpt 2) #

Beautiful nature brings beautiful mood, and beautiful mood brings beautiful life. For thousands of years, human beings have constantly recognized, utilized and transformed nature to benefit themselves. "There is moonlight in the pine forest and crystal stone in the stream", which makes us feel quiet; "The desert is lonely and straight, and the long river sets the yen", which makes us feel magnificent; "The butterfly dances from time to time, and the warbler just crows". Let's listen to the noise. "The spring water is as blue as the sky, and the painting boat listens to the rain and sleeps", which makes us close to leisure; "The leaves of Li Tang are rosy, and the flowers of Zizania latifolia are fragrant with snow", which makes us appreciate Ban Lan. Blue sea and blue sky, watching seagulls fly; Frozen snow floats, listening to Song Tao roar; Fei Ying grass grows and warblers fly, and birds and flowers are fragrant. In the morning, watching the sea gives birth to the sun; At night, look up at the shining stars in the light; On rainy days, let raindrops kiss your cheeks; Make snowflakes smile on snowy days; Feed the ants a good meal, water the flowers and honey; Greet the morning light "Hello" and bid farewell to the moonlight "Good night".

These amazing figures, the online vocabulary, have actually given us a solemn warning: if we just suck the milk of nature without taking immediate action, we will be destroyed in the battle to protect the environment and save our homeland.

So please start with me! Pick up a plastic bag from your foot, save a piece of paper from your hand, use less electricity from your home and throw away an old battery ... From now on, if every friend who has a car can drive less once or twice a week, and every classmate who asks his parents to pick him up by car can take the initiative to ask their parents to take a bus or ride a bike instead, we will have more blue sky. ...

If we don't want to wait for death, then we should wake up and consciously start from the little things around us, and the blue sky, white clouds and green grass will settle here. A trickle can merge into a surging sea, and patches of green leaves can create a vast forest. As long as each of us picks up the pen of environmental protection in our hands and adds a touch of green to this beautiful and ancient picture in the streets and alleys where we live, we can hide our home in a green and healthy ocean.

Let's act together, win this environmental protection competition with our collective strength, make the earth beautiful, make the land that we have thrived for generations cleaner and give mankind a better living space!

# Speech on the theme of environmental protection (selected article 3) #

Student:

The theme of my speech today is "protecting the environment and cherishing the earth".

We live on the earth because it is the only place where we can live. Without sunshine, plants, oxygen and water, we can't live.

But do students know? Mother's green on the earth is turning yellow bit by bit. Scientists estimate that in the near future, if the flower of morality is in full bloom, the mother's green color will disappear. I once had a real dream that the whole world was desertified. At first glance, I can only see boundless sand and black sky. I walked to a spaceship. ...

Do the students know the green speech? Mother will face a disaster-global warming, melting ice and snow in the Arctic and Antarctic, rising sea level, flooding of the earth, ozone hole over Antarctica, disappearance of air and mass extinction of animals. ...

But do students know? The water that we can directly use accounts for only 7/100,000 of the world's total water, which can be said to be minimal. But these floods are constantly polluted, and the color of water on the earth is constantly changing. ...

Watching TV the other day, I learned that in the Yangtze River, the Chinese sturgeon unique to China has been extinct, and the living fossils that have made dozens of generations of China people proud have disappeared from our eyes.

I have a wish. I want a three-color earth, where the water is blue, the ground is green, the clouds are white, the forest coverage rate is 100%, the blue sky and white clouds set each other off, and there is only an attractive green earth.

Let's protect the environment and cherish the earth, so that the last drop of water is not human tears, and the last breath is carbon dioxide exhaled by people. Study hard for the tricolor earth!

# Speech on the theme of environmental protection (selected article 4) #

In the vast and beautiful universe, the birth of a new star gives a new life a home. Green grassland, quiet jungle, blue ocean. ...

Everything is so beautiful, that is the place where we live-the earth. People living on the earth have different races, different appearances and different ways of communication, but the only thing that is the same is that we are all children of the earth, connected by blood and soul mates.

As early as hundreds of millions of years ago, dinosaurs appeared in this fertile land, breathing fresh air. Tens of thousands of years ago, dinosaurs died out and new animals and plants appeared. It's their turn to breathe fresh air. Thousands of years ago, our ancestors appeared, they lived in various ways, they used their own methods to protect the beautiful nature, and nature became more vibrant.

From ancient times to modern times with extremely rapid economic development. People forget the kindness of Mother Earth to us and hurt her unscrupulously. For our own benefit, we seriously damage the environment and cut down trees unscrupulously. To this end, we have also been punished as we should: floods, sandstorms ... these disasters swept through and killed countless people.

Everyone must have learned the "food chain"! By learning the lesson of "food chain", we can know that everything depends on grass. For example, on the grassland, mice eat grass, snakes eat mice, and eagles eat snakes ... Now, for example, the grass on the grassland suddenly disappeared overnight, and the mouse lost its food source and had to starve to death. The mouse starved to death, and it is just around the corner to let the snake die. Finally, it's right in front of us.

Why did the grass disappear? The culprit is us humans. Because human beings keep making rubbish, the biological chain on the earth is out of balance. If we throw away an abandoned battery casually, even in a small corner of a piece of land, there will be no flowers and plants in that small corner and its vicinity all year round, and even flowers and plants may never grow.

If we throw a piece of bread near the plant, it will soon rot and mold, and finally attract a group of flying insects. After they stay on the bread for a while, they will soon produce new destroyers to destroy it. This time, the object of their destruction is the flower. Since we have chosen the earth, we should take good care of it and create a beautiful environment for our life. Let's work together!

# Keynote speech on environmental protection (selected article 5) #

Hello, dear teachers and classmates. I'm Yue Huang from Class Two, Grade Two. This time I'm here to run for the star of environmental protection and energy conservation.

Protecting the environment is the responsibility of every citizen, and protecting the environment should start from us. For example, we can use environmental protection bags instead of plastic bags. Plastic bags can't be recycled and degraded, and the last resort is incineration or landfill, which is very harmful to the environment. In order to solve this problem, we should refuse to use disposable plastic products.

Energy saving can also be achieved in many ways. On weekdays, I treat my unused exercise books as drafts and try to stuff paper into them. No correction fluid is used. At home, you can replace ordinary incandescent bulbs with energy-saving lamps. Under the same luminous flux, energy-saving lamps save 80% electricity compared with incandescent lamps, and the cost of purchasing energy-saving lamps can be recovered from (8 ~ 10) months of energy saving.

Various household and office appliances, such as televisions and computers, can be turned off when not in use. In standby mode, the average power consumption per hour of TV set, air conditioner, monitor, PC host and range hood is 8.07 Joules, 3.47 Joules, 7.69 Joules, 35.07 Joules and 6.06 Joules respectively. Turning off the power supply can not only save electricity, but also protect the environment.

At school, we should turn off the tap when we see it is not turned off, which can save valuable water resources. Try not to waste food when eating. Take care of greening. Plants can not only beautify the environment, but also maintain soil erosion. Therefore, environmental protection and energy saving are not difficult, and can be reflected in many small things in life. Please vote for me.
