Will Martian immigrants attack the earth?

The earth, our home, was inhabited by dinosaurs hundreds of millions of years ago. Now we humans and many animals live in this beautiful land, just like a fairyland.

In the past, the sky was blue; The water is very clear, and you can see the posture of fish dancing in the water, which is very cute; Trees are growing tenaciously, everywhere is green, and flowers and grass are everywhere all year round. In this green land, everyone has beautiful memories.

But I don't know when people began to cut down trees indiscriminately, which has destroyed the ecological balance of nature. Lack of plant cultivation in science, frequent avalanches; There are no tall and straight trees and lush grasslands on both sides of the approach road, which becomes smoky. Due to people's logging, some forests were originally lush, but only trees were left. Mother Earth's original hairdressing has become very sparse, and dense forests are rarely seen on the mainland. ...

I don't know when people started killing animals for their own benefit, which made them very miserable. As the name implies, a "hunter" is a person who mainly kills animals. They are very cruel, animal killers, cold-blooded and heartless guys. A bullet from the gun in their hand can kill an animal on the spot. If all the animals in the world are extinct, they have nothing to kill. Will they aim their guns at their compatriots?

There are countless examples of people destroying the natural ecological environment. Every time they think about it, their brains will picture how many years later the waves on the earth are unbearable. ...

People! Wake up! To know that the earth is unique, it has provided all our needs for so many years, and we should learn to be grateful. From this moment on, let's join hands and build a green levee to protect our earth!

The elevator stopped at 172 floor, and a man with glasses and a little baldness came in with several stacks of papers.

"Oh, isn't this Mr. Levin?" The device looked very honored and smiled and shouted to the people.

"Yes, Ann, long time no see." Raven interface

"What happened to your crow plan?" Ann is still full of irony.

"How many times have I told you that raven means crow, not crow!" Raven paused, then added with a smile, "Thanks to you, the implementation of the plan is just around the corner."

"Impossible, the government will not approve such a crazy plan." Ann said this, but her heart sank rapidly with the elevator. "that is to let all mankind die ... we only have one earth."

"Ha ha," Raven looked at Ann's environmental report. "We only have one earth, but we also have Mars and Mercury, and ..."

Ding! The elevator door opened and Raven went out without looking back.

I hope it's not true, damn crow ... Well, Project Raven. Ann looked at the beautiful scenery outside the transparent elevator: sunshine, beach, blue sea and blue sky. It is said that this project is called Raven Project because it is a big migration, but even a fool knows the actual reason. Raven is too selfish to name this ridiculous plan after himself, hmm. Ann put her hand on the elevator glass and looked out. What a charming scenery. It would be great if she reached out to feel the mild sunshine in October. But Ann knows this is impossible-the scenery outside is a simulated hologram, and the real scene is likely to close her eyes, which is very frightening.

In the near future, even the author can't tell exactly what year it will be, and the environmental situation of the earth will be seriously polluted and on the verge of destruction, as scientists worry now. Of course, this "edge" is relative to the ancient earth, and it has been several generations for human beings. Humans sometimes discuss this problem, but more often they do their own thing to earn money to support their families. No one believes that they can see the destruction of the earth in their lifetime. The pollution of the earth is really serious, so I put on a gas mask and went out, beginning to feel strange. After a long time, I got used to the scene where everyone was like monsters.

However, the deterioration of environment finally forced people to face it. In the heated discussion, two factions were formed. Radicals argue that since the earth is going to be destroyed, we should step up the transformation of other planets and hold a big relocation; Conservative advocates will naturally try their best to eliminate pollution and restore the beauty of Mother Earth. At first, there were many conservative people, but with the gradual deterioration of the earth's environment and the gradual establishment of the Martian atmosphere, conservative people also fell to the radical side.

The dry land has faded red, covered with thick seaweed and busy with photosynthesis. The polar ice caps are gradually melting and rivers are slowly spreading on land-Mars, once a red planet, is rapidly evolving towards its sister.

The commotion began from that moment.

With a bang, a pot of flowers was heavily placed on the ebony table. Raven looked up in surprise and said, "Ann, is that you?"

The flowers on the table are called blue willow fish. Ann is obsessed with the beauty of flowers and has been carefully maintaining this pot of flowers with strange scientific names. It is said that Ann tried to throw away the gas mask and commit suicide on the day when the government exhausted the earth's resources to power the Mars immigrant ship, but she finally survived because of this flower.

But now, this flower has lost its pure sky blue and turned into blood red.

"Variation!" An Chaorui heard the sound and shouted: "Damn Mars protovirus!"

Raven tried to keep her voice gentle. "Oh, maybe it's someone's prank?"

"no!" Ann patted the table and said, "She keeps changing shape!" "

Like hearing the command, the flowers changed from red to light, and finally the petals as white as paper withered and fell to the ground. At the same time, the stem becomes thick and black, and thorns grow out.

"My God!" When the incoming documents saw this scene, they rushed out of the door.

The commotion spread around at the speed of light, covering the whole planet.

Ann is dead. She went directly to the no-man's land without a protective cover-the earth people moved to Mars for only five months, and many areas were not rebuilt, so the powerful Martian storm left her.

The commotion gradually subsided, but the reason was the spread of the plague.

Two satellites of Mars quietly lit up the office building at the foot of the 25,000-meter-high Mount Olympus, and the only living person in the isolation room of the building was struggling to support it. I'm dying, Raven thought, the original Mars virus ... Raven suddenly thought of Ann's "We only have one earth", smiled bitterly at the direction of the earth and closed his eyes.

Raven walked in the sunny street, but his heart was a little tight. Just now, he watched a disaster film, and human beings were destroyed again among Hollywood directors. But the hero has the same name as me, Raven thought, and he is still a villain! Raven threw the popcorn paper bag on the ground. Time to go home!

Wait a minute. Why does it feel wrong?

Raven looked back, smiled and picked up the dropped paper bag and threw it into the combustible trash can. I feel much more relaxed now.

Environment is closely related to human life. It provides people with all kinds of materials and energy, and is the material basis for human survival and continuation of the race. Because human beings don't cherish the environment, their arbitrary quality is greatly reduced, resulting in environmental problems. The air is polluted, the land is polluted, the water is polluted, the land is polluted, and the beautiful home of mankind is unrecognizable and scarred. The environment's tit-for-tat revenge on human beings is unstoppable, and even seriously threatens human survival. Protecting the environment has become a global topic, and it is urgent. The reason is simple: we only have one earth!

The environment should start from me and start from the side. Although what we do is trivial, if we unite, we will have great power. In view of the actual situation of our family, I think we can strengthen parents' awareness of environmental protection and establish environmental protection concepts. We used to use disposable wooden chopsticks in restaurants, but now we bring our own chopsticks to reduce the felling of trees.

Environmental protection is not a big deal, but it permeates small things. Once, it rained cats and dogs at night, and the rain splashed on the glass. The next day, it cleared up. Go out and have a look, the bird's nest on the branch is gone. The heavy rain last night must have destroyed the birds' homes. I heard the sad cry of the bird, and I lost my old anger, as if to say to me, "Help me!" " I am homeless now. "I thought of this dull pain in my heart and went home. I went home and told my parents. Dad said, "let's build a new home for the birds!" Let them have a new home. "So we started to act. In the afternoon, we just made ten bird's nests. These bird's nests are made of wooden boards and are not easy to be damaged. Birds don't have to worry anymore. Rain will damage the house. After that, I took the bird's nest and put some millet in it. Father carried a ladder, nails and hammer, and we came to the big tree together. Dad climbed the ladder and nailed some nails in the tree. Then hang the bird's nest on it. After a while, birds flew in. Such a simple action is nothing to us, but it is very important to birds. My father, mother and I walked on. We have nailed all ten wooden cases. On the way home, the birds chirped at me, probably thanking us.

I remember I once wrote an essay called "How to sweep the world without sweeping a room", so during the winter vacation, my mother and father set an example and cleaned up the white garbage in our community. When the community is bright, so are our hearts. How I hope everyone can join hands to create our beautiful home. I hope everyone will remember the sentence "We only have one earth".
