Atmospheric Pollution Essay 2: Air Pollution

This morning, I woke up and found that the sky was blue, the kind of gentle waves, pure blue. The blue is intoxicating and refreshing.

The sky is so blue today because it has been cleaned by the storm, otherwise it would still be gray. Why is this happening? When my parents were young, the sky was still blue. The culprit behind all this is environmental pollution.

The exhaust gases generated by factories during work are directly discharged into the blue sky without treatment, and the exhaust gases generated by companies burning gasoline are also dispersed in the air. At the same time, with the development of the economy and the increase in population, energy consumption has increased, and the waste gas generated has also increased many times. The number of cars, motorcycles and other motor vehicles is increasing rapidly, and their exhaust emissions are increasing. These exhaust gases contain large amounts of carbon dioxide and soot. This causes serious environmental pollution. Environmental pollution in turn causes atmospheric pollution, which causes the sky to turn gray.

The harmful effects of air pollution are not just gray skies, but sometimes life-threatening.

In the early morning of December 3, 1984, the Bhopal, India, incident that shocked the world occurred. At midnight, a toxic gas leak occurred from the security gate of a pesticide factory located on the outskirts of Bhopal - a pesticide factory that stores 45 tons of chemical hazardous substances.

Soon toxic smoke hit the city. A poisonous fog-shrouded area with a radius of 25 miles was formed. First, hundreds of people died in their sleep in two neighboring towns; then some beggars died in the train station. When the poisonous fog spread significantly, residents panicked. Some thought it was an "atomic bomb explosion", some thought it was an "earthquake", and some thought it was "the coming of the end of the world." A week later, 2,500 people died from the pollution accident, more than 1,000 people were in critical condition, and more than 3,000 people were critically ill. 150,000 people entered the hospital for treatment due to pollution hazards. Four days after the accident, the number of affected patients was increasing at a rate of one per minute. The accident also blinded more than 200,000 people.

It can be seen how harmful air pollution is! In order to alleviate air pollution, please start with small things around you, do not burn fires in the wild, and try not to use cars with high exhaust emissions... I believe that with your support, the harm caused by air pollution will disappear! ! !

Air Pollution Essay 3: Fight Air Pollution Together

Nowadays, the pollution in our cities should be getting more and more serious, and our once green home is gradually disappearing. It is precisely because of this that we must stop these sources of pollution.

I think the most serious problem now is air pollution. There is a slogan that says "Smoking is harmful to health", but most people today are still smoking. Smoking not only harms people's physical health, but also harms the health of the environment. The smoke adds a touch of blackness to our cities.

Look around, what can you see everywhere on the streets? It’s all kinds of cars! Nowadays, most people have their own cars, but the exhaust gas emitted by various cars pollutes the city. You can imagine how many cars drive by on the road every day, and how much car exhaust collects in the air, causing the air to be polluted.

Around us, air pollution invisible to our naked eyes is floating everywhere, and they dominate our entire city.

To deal with these stubborn sources of air pollution, of course we have to take some "measures". First of all, we can do publicity campaigns about "smoking is harmful to health" and make suggestions to people to smoke less, or even not to smoke. Then, we should try to reduce traveling by driving ourselves. It is best to take a bus, ride a bicycle, or even walk. If there were dozens fewer cars on the road every day, the air pollution in our cities would slowly decrease. Finally, we need to promote more tree planting. Trees can absorb some harmful gases in the air and produce new pure substances for human beings to breathe. In this way, the air pollution in our cities will also slowly decrease.

So, from today on, each of us must be an environmental pioneer. We must fight against air pollution together. We must defend our city and make our city truly a A healthy, pollution-free city becomes a truly green home.

Air Pollution Essay 4: Air Pollution in Hometown

My hometown is in Qiandao Lake. There are lush forests, crystal clear lakes, deep blue skies, fresh Sweet air.

Unfortunately, some unconscious behaviors of people in my hometown are still affecting the environment here. For example, setting off fireworks and firecrackers during the New Year and festivals seriously pollutes the air (our home has the most polluted air this year). Let’s take our family as an example.

On New Year’s Eve, before having the New Year’s Eve dinner, my father went downstairs to set off firecrackers. The sound of crackling firecrackers sounded, and in an instant the downstairs turned into a heaven. The ground could not be seen, as if it were all clouds. I felt like I was in a sea of ??clouds, filled with thick smoke, giving people a suffocating feeling.

There will be even greater smoke at night.

We watched the gala first... As the TV show counted down, "five, four, three, two, one", almost at the same time my father and I raised the firecrackers downstairs to set off to welcome the new year. arrival.

Crackling, only the sparks of the firecracker explosion were seen. Damn it, I can't breathe fresh air. I ran into my house as fast as I could, shutting the door and closing the windows. Breathing hard.

That night, the sound of firecrackers kept ringing for several hours, which kept me awake all night. Either I dream of injuring others, or others injure me, causing me to wake up all the time.

I think if we want to make the environment better again, we should set off less firecrackers, smoke less, and make our environment as beautiful and charming as before!

Air pollution essay five: Give me back the blue sky

The white clouds are floating in the blue sky. This is our memory of the beautiful sky and the memory of childhood. Nowadays we rarely see such a beautiful "sky", especially in cities or industrial areas, where it is smoky and hazy all day long, which is really unpleasant. Faced with all this, you may not be able to help but sigh: "Fresh, refreshing, and clear atmosphere, where have you been? Quickly cure the "disease" of the atmosphere and give me back the blue sky and red sun!

We do have a lot to do, the most important thing is to try to reduce the emission of pollutants.

Smoke and dust are mainly produced by the incomplete combustion of coal and oil. Improve the combustion method to ensure that the fuel is fully burned. , can greatly reduce the amount of smoke and dust generated.

Try not to burn loose coal, develop coal gasification and liquefaction, and wash and process the fuel containing a lot of ash and sulfur before using it. Pollutants must be recycled, processed, turned into benefits, and reused through absorption, catalysis, adsorption, condensation, etc.

Even pollutants that escape into the atmosphere must be managed to reduce their harm. We must strengthen urban greening, plant more flowers, trees, and open more parks and boulevards.

From the perspective of stopping global warming, we must control the growth of greenhouse gases, especially carbon dioxide gas. , we should try to use natural gas as fuel. If we can eliminate small chimneys in each household and implement centralized heating or joint production of power supply and heating, we can save fuel and reduce carbon dioxide emissions.

The world. If the amount of secondary reuse of aluminum in each country is doubled on the current basis, 1 million tons of pollutants can be reduced into the atmosphere a year.

There are more than 400 million cars in the world every year. Approximately 1.83 billion tons of carbon dioxide will be emitted. In order to reduce greenhouse gas emissions from cars, in addition to limiting the number of cars, saving fuel consumption, and installing purification devices, we must also try relatively clean fuels such as methanol and ethanol, and develop public transportation. Tools and electric vehicles.

Finally, the most fundamental way to reduce air pollution is to develop and utilize clean new energy, such as nuclear energy, solar energy, wind energy, biomass energy, geothermal energy and other clean and abundant reserves. , promising development.

The destruction of the ozone layer is a global problem.

The United Nations Environment Conference decided that by the end of 1995, the production of chlorofluorocarbons, the "primary culprit" for damaging the ozone layer, would be phased out. However, the lifespan of chlorofluorocarbons is 50 to 100 years. Of the 15 million tons of chlorofluorocarbons that have been lost and released into the atmosphere, only a small part has so far damaged the ozone layer. Most of the rest are still acting, and the ozone layer will continue to was destroyed and reached its peak in the first decade of the next century. As for completely returning to normal natural levels, it will take at least a century!

Air pollution is caused by human activities, and ultimately must be solved by humans themselves. It’s just that time waits for no one. We’d better act resolutely from now on, take measures to purify the atmosphere and give us back the blue sky!
