On Sunday morning, I wanted to open the door and look at the blue sky, but I looked up at the sky. What about the blue sky?

It no longer exists. On the contrary, Mother Earth's dusty face.

My father and I went to nearby Shacheng to refuel the car. Just arrived at the gas station, a gust of wind mixed with countless dust hit us, and I almost vomited. What is that smell? Choking, smelling disgusting.

After refueling, I was about to get on the bus and go home, but I was surprised to find that in just a few minutes, the car was covered with countless dust.

Looking ahead, two big chimneys are constantly emitting a lot of smoke into the once beautiful blue sky.

There is a story about the giant and his shadow:

More than 600 years ago, a baby was born on the earth. He is a giant, and the shadow lives with him.

Huge manpower is unparalleled and invincible, but some idiots often do wrong things; Shadows are much smarter than giants. He knows why the wind is chaotic, why it rains, why the sky is flickering and why the earth can't go to the end. He taught the giant many things.

But later, the giant learned a lot. He can shoot flies with missiles and chase rabbits with planes. Live a good life, the giant grows bigger and bigger, but the shadow is malnourished, small enough to hide between the giant's fingers. The giant is getting bigger and bigger. When he opens his mouth, it is seven square kilometers. The world population has reached 5.7 billion, which is about 7 square kilometers according to the area of each person's mouth.

He kept destroying the earth, but his shadow brother was too young to stop him, became smaller and died at last. Giants have been destroying the earth and never stop. He poked a big hole (hole in the Antarctic ozone layer) in the sky.

What will happen to giants?

Objectively speaking, since 500 BC, human beings have made great achievements in natural science, but we have made little progress in humanities, just like giants and shadows in stories.

Humans have gone the wrong way! Looking back, we walked all the way, but behind us was a mess, complaining, and the world behind us was collapsing. How far can we go at this speed? Looking back at human history, we used to have two paths. One is to consciously develop our inner world and strive for spiritual peace and sublimation. One is to transform the material world and strive to occupy more material life. The former road has been mercilessly criticized by modern science, and the latter road is being reflected and doubted by modern people. What's left of the poor human?

Come back, lost lamb! Lawless humans! Please stop and wait for your soul! Give us back the blue sky!
