"Boom-"There was a loud noise, and the spacecraft had landed safely on Mars. I came to Mars as the fifth batch of immigrants in 2040. At this time, the gentle voice of the staff sounded in the spaceship: "I think everyone knows that due to the over-exploitation of human beings, the earth's resources are exhausted and the environment is deteriorating, so everyone will immigrate to Mars. Ok, please put on your clothes, line up and get off the ship. " Wow, when I got out of the spaceship, a green "grass" came into view. It was so beautiful! There are rows of green "trees" and a garden full of all kinds of "flowers". The environment is really good! Just as everyone was intoxicated with the beautiful scenery in front of us, a tour guide told us: "In fact, it is impossible to grow plants on the land of Mars, so these flowers and plants are all made of chemical synthetic materials-carbon glue. Don't underestimate that although they are synthesized from chemical materials, they all have the characteristics of all plants, such as emitting fragrance and preventing soil erosion, and their service life can be as long as one hundred years! " "

Even plants can imitate so exquisitely, and human wisdom is really endless. "I thought with a smile." But where did the water and food come from? "The person traveling with him asked," Didn't you say it can't be planted on Mars? Where is this plant planted? "

The "guide" pushed his glasses and explained with a smile: "Yes, plants can be planted on the surface of Mars, so why not plant them on the surface?" Look-"We look in the direction of her finger. It's a huge building in the shape of a mushroom." The house is divided into two floors. The lower layer is for scientists to study how to make plants grow rapidly and eat them harmlessly when they mature, and the upper layer is equivalent to their laboratory. All research should be carried out. If the experiment is successful, the seeds of these plants will be sent to nearby high-rise buildings for large-scale planting. The "guide" paused and continued: "Of course, all these foods are still planted in the soil. Everyone will definitely wonder, how can there be soil? In fact, these soils are all shipped from the earth; Of course, before using these soils, they must be purified through complicated procedures and added with sufficient nutrients and fertility, and then used to grow vegetables and fruits! "

"Oh!" Everyone nodded thoughtfully. "As for water, it is also brought from the earth," said the guide. "How is it possible, how can you drink the water on the earth? -"everyone is very strange, noisily talking about. "Well, the drinking water on Mars is actually formed by melting glaciers in the polar regions of the earth. Let's transport the glaciers on the earth to a large water factory on Mars to melt them, and then remove the impurities from the water, so we can drink them. This water is rich in many minerals, just like mineral water, but more nutritious than ordinary mineral water! " The "guide" explained while pacing.

"wow! Awesome! " Everyone clapped their hands involuntarily. At this time, the "guide" smiled mysteriously at us and asked, "I wonder if you have noticed why we can walk so easily and breathe so freely when we get to Mars?" "Yes! Not to mention, I really don't remember. What is this? " I asked curiously. "In fact, thanks to this suit on us! This is an improved version of the spacesuit, which can help us walk as freely as on the earth. It is also a strange air converter, which can convert the thin gas on Mars into air with similar composition to the earth, so that we can breathe freely. " The "guide" patiently explained.

"Well, I think everyone may be tired. Now I'll take you to rest. "

As you can imagine, I will live a happy life on Mars in the future-however, this life will not last long. About two years later, I was "honored" to be the fifth batch of immigrants who were about to set foot on Mercury! Yes, it's also because Mars really can't support the speed of human's' development' and its resources are almost exhausted.

"Oh, my God-"I cried in pain. ""ouch! "I was hit hard on the head. It's my mother. " What are you dreaming in broad daylight? "My mother said a few words to me and walked away. I hurried out of the house. Fortunately, the grass is still there, the trees are still there, and the water is still there. Of course. What happened afterwards? Who can guarantee that nothing will change in the future, and who can guarantee that my dream will not become a terrible reality! I can't help shivering-
