The impromptu speech of haze

Smog is not terrible, as long as everyone can take it seriously, starting from me, and actively protect the environment. Below is a collection of impromptu speeches about smog that I have collected for everyone. Welcome to learn from it.

Speech on Smog Prevention

Dear students:

I heard from the elders that Beijing was not like this in the past. In the past, the sky in Beijing was blue, there were not so many people, and there were not so many cars. But Beijing now is a different story.

Why does smog occur? It turns out that it is mainly caused by three substances: sulfur dioxide, nitrogen oxides and inhalable particulate matter. The main sources of these three substances are automobile exhaust, exhaust gas generated by burning coal for heating in winter, and dust generated by construction sites and road traffic. The harm of smog is not small! It can cause various diseases, especially respiratory infections, and it also brings a lot of inconvenience to people when traveling.

What can we do to reduce the occurrence of smog? How should we protect ourselves when there is smog? I think we must first travel green and reduce the number of self-driving trips, thereby reducing vehicle exhaust emissions. Thirdly, try to use clean energy for heating in winter to reduce the generation of soot. Finally, plant more green plants to reduce the exposed area of ??the land, thereby reducing the generation of dust. When there is haze, you must do a good job in personal protection, go out less often, wear a mask correctly when going out, wash your face and hands in time after returning home, and maintain good personal hygiene.

Smog is not terrible, as long as everyone can take it seriously, starting from me, and actively do a good job in environmental protection. I believe the weather in Beijing will definitely get better and better.

Protect the environment and stay away from smog

Dear teachers and students:

Good morning everyone! I am. The title of my speech today is "Protecting the Environment" , stay away from the haze.”

In the past few days, the biggest news in the newspapers has been the haze weather, which has caused schools in many places to suspend classes for several days. The biggest enemy we face now is a variety of environmental problems! Air pollution exceeds standards, the greenhouse effect is enhanced, land desertification, water pollution is serious, species disappearance is intensifying, haze phenomena are increasing, etc. Why are there more and more environmental problems? It is because of our unreasonable use and destruction of natural resources and ecological environment.

On campus, we often see some scenes that we don’t want to see: paper scraps and food bags on the playground, stairs, and corridors; handprints and footprints on the snow-white walls and ball marks; are there hard-to-remove chewing gum stains in the classrooms and corridors?

A journey of a thousand miles begins with a single step. To protect the environment, we must start from me and start from small things. As long as we develop good habits, don't litter, don't waste food, save water, save energy, save paper, refuse to use disposable "white pollutants", plant more trees and grass, etc. Then, the sky above our heads will become bluer, the river water around us will become clearer, the birds in the sky will chirp louder, and the people living there will become healthier and happier.

Let us all start taking action today to protect the environment, starting with me!

Thank you everyone!

Sample Speech on Smog Prevention

Dear teacher, dear students, hello everyone:

I don’t know since when, the sky is no longer blue, the clouds are no longer white, the air is no longer fresh, take a breath of turbid The air, "cough, cough" sounds are coming and going. Which "murderer" is causing this? I found this "demon" haze on the news.

Smog is caused by automobile exhaust, chemical plant exhaust and fireworks. Smog can also cause great harm to our bodies, such as acute bronchitis, rhinitis, asthma, etc. It is especially harmful to the growth and development of our teenagers. ?

In the future, we should open less windows, drive less, and go out less; eat more vegetables and fruits, and pay attention to environmental protection, so as to reduce the formation of smog. We can't burn straw yet, plant more trees and cut down less.

I will introduce to you some vegetables and fruits that can prevent the harm of smog, such as: white fungus, lily, and fungus? Although these are things that many of my classmates don’t usually like to eat, I must eat more of them in the future. , enhance the body’s resistance.
