People shouted at the smog:? Lan, go back! You devil, we don't need you! ?

Haze laughed after listening:? Actually, you invited me back! If you hadn't driven cars to emit exhaust gas every day and opened so many factories in the suburbs to emit exhaust gas, I would have strengthened my strength and cut down my most powerful enemy trees and vegetation. I'm not so good, I'm actually your guest! ?

The sun came out, and he couldn't penetrate the thick smog to bring people sunshine.

The sun looked at the thick smog and thought for a long time. Finally, the method of subduing smog was realized.

The sunshine cries to people: Since smog is afraid of trees, plant trees quickly; Since the power of smog comes from automobile exhaust, drive less! Since the smog comes from our polluted environment, let's change the environment! ?

The formation of smog has affected many people. Experts say? Haze is formed by a large number of tiny bacteria such as dust, sulfuric acid, nitric acid and organic hydrocarbons in the air. ?

People leave many traces in the smog, such as automobile exhaust, chemical plant exhaust and chemical plant sewage.

People have left enough for future generations in this world, but now everyone has left a very bad gas for future generations, which is our current smog.

We must all unite against the new reinforcements of the virus, General Lan. We can plant more trees and drive less. We should wear masks every time we go out! We also try to go out as little as possible.

Haze also affects our mood. When driving, you must pay attention to the safety ahead. Don't drive tired because of smog. When you encounter something bad, you should control your emotions, and don't be grumpy and solve it calmly.

In traffic, don't be impatient, because there is fog, there will be fog, so traffic jams and traffic accidents are prone to occur.

So please protect the smog together! Let's act together.

We should all do more exercise together, try not to go out when there is smog, and don't go out unless there is something urgent. We can also do some small sports indoors.

Let's protect the earth and our home together!

Let's leave now. Is this cigarette poisonous? I looked at it and flew away reluctantly. I believe those stupid humans will be punished. I looked at the chemical plant with hatred. Unfortunately, I'm just a sparrow with little strength.

Several months have passed, and the chemical plant is still running, but human beings have paid the price for what they have done. Look at the smog in that city. Does the earth think that mankind has lost? Then release smog to remind people?

Fortunately, people have realized their mistakes, and many people are protecting the environment. But will the spilled water come again? Man can only pay for his actions. If mankind does not know how to repent, then the day when the earth dies will also be the time when mankind dies.
