Essay on the protection of the earth after 500 years

The Earth in 500 Years The Earth in 500 years will no longer be the mother of the human in the blue veil, she has been scarred and turned into the grave of humanity.

On Earth, trees are scarce, the concentration of carbon dioxide in the air is increasing, and the sky is gray and the sun is invisible, and it is impossible to distinguish between day and night. The order of people's lives was disrupted, they went insane, and they were admitted to the hospital. Suddenly, it started raining, and it was acid rain.

The rain fell on people's **, and there was ** disease, causing a moment of chaos. Who's to blame for this? It is the only home that human beings themselves do not protect well.

Ping-pong", there was a loud bang, and soil erosion caused a mudslide. It's just a normal day. The next day, it stopped raining, but the sandstorm swept in, and I don't know how long later, the sandstorm stopped, and the whole city was covered with yellow sand.

People started planting trees, but the sky "surrounded" by carbon dioxide could not get a ray of sunlight, and the plants could not photosynthesize, and they all died. Now, there is no return, but if this continues, the end of the earth is coming.

At an auction, the auction is nothing but the last drop of pure water on earth. It is packed in a special box so that it does not evaporate. At this time, someone bought it at a sky-high price of 10 million yuan.

After that, the second thing came out, a green leaf, and the last green leaf on earth, and of course, it was also sold for a sky-high price. At this time, the alarm sounded in "Dudu": "Listen, everyone, the oxygen on the earth will run out in three years, please leave in our spacecraft in one year; Listen, everyone, ...... in a year"People are gloomy.

yes, what else can people say at this time?

A year, time is like an arrow, and it has come in a blink of an eye. Renmen left the home where he had lived in the spaceship. People say goodbye to Mother Earth again. The earth wiped away its tears and thought: Where are you going, my dear sons and daughters?

Students, take good care of the earth, there is only one earth, and destroying it is equivalent to destroying us human beings. Take care of the planet! Start with me, start now, don't let such a tragedy happen! May the earth live forever.

Yes! The beautiful earth, blue and white, gave birth to human beings, and human beings live happily on the earth ......

With the infinite luxury of human beings, the earth is slowly weakening, and the beautiful earth will no longer belong to us. You see, although the high-rise buildings on the side of the road have risen from the ground, there is countless garbage on the road. At this time, a young man had just finished eating a banana and threw the banana peel into the ground, alas!

If an old man accidentally stepped on a banana peel, the consequences would be unimaginable. Walking into the farmer's market, it was dirty, the ground was full of sewage, people came and went, and the sewage was carried to the road. The vegetable sellers shouted, the vegetable buyers talked about the price, and there was a commotion inside.

When I walked out, I saw plastic bags everywhere, ...... on the ground, in the air, and on sun umbrellasPlastic dolls can be seen. People never pick up plastic bags, and they accidentally float into the air, and they don't care, it's really "obscure"! Walking into the woods, I saw beautiful, tall trees, fragrant flowers, thriving grass, happy frolicking birds, fluttering fallen leaves, and the woods were filled with a joyful atmosphere.

However, the good times did not last long, and after a few days, some money-hungry people came to the woods with axes in their hands. What are they going to do? Yes!

See, they were cutting down the trees with great effort. Both the old and the young trees have suffered misfortunes and lost their lives. When they cut it down, they take it to the market and sell it.

Falling red is not a ruthless thing, turning into spring mud is more protective of flowers". When a flower loses its tree, it has no fallen leaves to fertilize it. What about the grass?

Without a tree, there would be no umbrella to shelter it from the wind and rain. When birds lose their trees, they don't have a comfortable home. The earth, our beautiful home, will be far away from us.

Because of our extravagant hopes, the earth will soon perish. There is only one earth, and if we destroy it, we will not have a stable home, and we will even face the ...... death

The Earth is now disappearing, and in the near future, there will be no more Earth in the solar system. However, as long as we take care of the environment and protect the creatures on the earth, it is still possible to save the earth. Let's save the planet; Let's love the earth; Let's build this beautiful home better.

The earth is protected and we relax.

Changes in the environment.

One day a few years later, I returned to my hometown from out of town, sat in a solar-powered eco-friendly taxi, and learned from the conversation with the driver that the wasteland polluted by garbage and wastewater in my hometown has been transformed into a green space for people to enjoy leisure and entertainment. There is an increasing focus on planting green trees in cities; The exhaust gas and domestic water discharged from the factory are discharged after environmental treatment. Now the air is fresh and sweet, and the sky is getting bluer.

As soon as I got out of the car, I entered the gate of the community and saw a group of people planting trees, including my parents. It turned out to be an annual tree planting activity in the community. I hurriedly put down my bags and went to the event with my parents.

The community is planted with a variety of flowers and trees, the trees are lush, and between the trees, spring flowers, magnolias, chrysanthemums, and moon seasons grow from tree to tree. In the center of the community is a small pond with lotus flowers, and small fish swim leisurely among the lotus flowers.

There is also a small control room in the community, and the domestic garbage is transported to the garbage treatment center through the underground transmission facility for centralized treatment; After the domestic wastewater is automatically processed by the computer, it is discharged to the small pond of the community for fish farming, and the flowers and trees in the community are watered regularly, and the remaining water is put back into the river through the city pipeline.

After dinner, I accompanied my father for a walk around the community. I saw that Longhu, which used to be smoky and overgrown with weeds, has now taken on a new look. My dad and I went to the lookout.

Standing on the lookout and looking around, I exclaimed, "Ah"! It turns out that the stinking and sewage water of the lake has been harmlessly treated by people, and it has become the sparkling and endless lake water that you see in front of you. Standing on the edge of the lake and admiring the small fish swimming in the water, the moist breeze blowing, which is refreshing.

I saw something in the middle of the lake and asked my dad what it was. Dad said, it's a sewage treatment plant. Now I understand why the water in Longhu Lake is as clear as a mirror.

It turned out to be the "credit" of the sewage treatment plant. It was it that treated the dirty water of the lake and turned it into the crystal clear water we have now.

The open space on both sides of the lake is surrounded by carefully designed flower beds, grasslands, bamboo forests, rockeries, and promenades. People come to the lake, and some of them chat about the interesting things of the day on the sand by the lake, while taking a leisurely walk; Some are watching the flowers that are blooming brightly, and a few words of praise come out of their mouths from time to time; There are also grandfathers and grandmothers practicing Tai Chi in the entertainment square, you see how much they are involved, the left punch, the right punch, the fight is good! At this time, there was a familiar sound of "pop, pop" in the distance, what was it doing?

It turned out that they were practicing Tai Chi fans.

Seeing this, I was amazed and envious, the environment of my hometown has become so beautiful!

Probably written. For example, human beings noticed that the earth was to be protected, and then human beings went to plant trees to protect the earth. Since then, human beings have lived happily ever after.

Or maybe some people are still obsessed. continued to destroy the earth, causing the earth to start running out of water and electricity, all resources were gone, and finally the human race became extinct...
