What I saw and heard in composition 600 on rainy days and bad weather

It's hard to see the blue sky when you wake up in the morning. It is often shrouded in a thick fog, and even the nearby buildings are blurred. This is the bad haze weather in recent days.

In recent days, there have been reports about smog weather in newspapers. Today's newspaper also has an eye-catching headline "Air quality will not improve significantly in the near future". The air quality is really bad The school broadcast said that there was serious toxic pollution, so let's not exercise on the playground. Exercising in the dirty air, we feel like vacuum cleaners.

The weather has become warm these days, but the fog is still lingering. Looking into the distance from the window, I am still confused. The corner of the sky near me seems to have improved a little, showing a little blue, but it is still gray. When I went out for a walk with my grandmother, I felt like I was covered in a huge glass cover and it was very difficult to breathe. When the gas is sucked into the mouth, it smells like disgusting dry powder.

Why do fog and haze linger? What did we do wrong? Is this a punishment from heaven?
