Elementary 3rd Grade Imagination Essay How to write an exam about the global environment in 20 years

Do you want to know what the Earth will look like in 20 years? let’sgo！

20 years ago and today, factories on the earth emitted a large number of sewage gases, sewage and other pollutants, 20 years later, on the earth, after the in-depth study of scientists all over the world, the pollution problem is already a small matter, and the environmental pollution problem can be completely controlled. Because scientists have mastered the most advanced pollution control technology, all the exhaust gas of the factory has been turned into oxygen, and the wastewater has become environmentally friendly tap water. In this way, it will not get sick due to sewage and sewage, and it will also make the urban environment better.

20 years later, the earth's cars do not need to use gasoline, because, scientists have invented an oil-free car, this kind of car is to use the sun's energy to make the car start, if there is no sun that day, it doesn't matter, because the car itself has 98% solar energy, if it is used up, don't be afraid, every car is equipped with this solar bottle, as long as the bottle is aimed at the absorption plate, the lid is opened, the solar energy is absorbed by the solar panel.

20 years later, our school has high tech! Because we have robot teachers in our schools, robots are made by our scientists who contribute to the world, and robots have our human brains, so they can judge and speak for themselves.

You see, 20 years later, the earth has changed so much, doesn't it make us happy and excited?

The earth's environment has been destroyed by human beings, and the original prairie is now also windy and sandy.

In 2032, the Minister of Earth Energy Management, pacing in his luxurious office, occasionally looked up at the dark sky outside the window, and sighed deeply. Suddenly, the office door opened. "Report to the Minister , the earth is completely depleted of oil!

A secretary grieved. "Report to the Minister, the last natural flower of the earth has withered! Another secretary choked up and said, he was thinking, human beings, have finally destroyed the earth?

A teardrop crossed the corner of the energy management minister's eye, walked to the window, and was in pain: "Mother Earth, we hurt you, you created us, but we ......Suddenly, the minister's eyes became ethereal, as if he was recalling his childhood twenty years ago.

At that time, the earth was a blue sky, white clouds were playing in the sky like children, the trees were shady, the breeze was blowing, and the long hair of the willow girl by the river was fluttering in the wind. Walking to the river, the water is crystal clear. The boat came, and the water rippled; In the sun, the water is shining.

The West Lake is beautiful, and the Taihu Lake is beautiful ......

Just like that, I looked at the blackened sky, and I was ...... in a dazeSuddenly, he shook his head and drank to the sky, venting the pain in his heart. "Is the earth really going to be killed by us? As he thought so, his hands clenched into fists and he vented his frustration with the people who were destroying the environment.

Thinking about it, he shook his head again: "Could it be that I used to care for the environment?" ”

Minister! Twenty years ago, the children set up the 'Little Guardians of Environmental Protection' organization, which saved three acres of grass! Minister!

The Little Guardians of Environmental Protection's organization has saved a few square kilometers of trees! Minister! Minister! "The Minister of Energy Management's eyes lit up, twenty years ago, a group of children who were so underestimated by themselves finally saved the earth's energy crisis?

The Minister of Earth Energy Management hurriedly ran to the window and looked at the sky - it was turning blue little by little! Looking down, the wasteland is already covered with tender green grass ......

We are the small members of the "Little Guardians of the Environment" organization. To protect the earth's environment, start from me, start from my side, influence others, and dedicate a love to the environment of our mother earth!

In the blink of an eye, it is already 2025, and although science has developed a lot, human beings have paid attention to the protection of the earth's raw wax. In the future, the earth's resources will gradually multiply from non-renewable to renewable resources.

A clear river flows in front of every house, and it has become a daily affair. The lush forests are full of life, the birds are chirping and flying freely, and the deforestation will be a mystery to humans 20 years later. All products made of wood have been replaced with computer high-fiber, and this high-fiber technology product, in 2025, will beat any wooden product, so that the trees will return to verdant and lush.

In the future, human beings will no longer use air conditioning, and because they know how destructive air conditioning is, people will become more and more cherishing the earth. Since then, the hole of the ozone layer over Antarctica has become smaller and smaller day by day, and finally in 2026, our wonderful ozone layer will close around our earth, and the strong ultraviolet rays will not be able to penetrate our home, and Mother Earth will no longer have to endure hellish torment.

After 20 years, the vehicles no longer run on gasoline, and they all have a maglev function. The "driver" of each car is a computer, and as long as you enter the address you want to go, you will set off immediately. It can be as close as five minutes and as far as twenty minutes.

This feature has multiple benefits: the time is greatly reduced; It does not damage the ...... the environmentWow!

Mother Earth 20 years from now is a ...... of Mother Earth full of smiles

This forest.

It is not only the scene of Europe hundreds of years ago, but also the scene that will appear on a large area of land about 300 years after the disappearance of human beings. What's even more amazing is that in today's Bialowizia Forest, the most primitive bison can still be seen, about 600 of them. In the forest, on the border between Poland and Belarus, the Soviets built a barbed wire fence to prevent nationals from fleeing to Poland.

Although wolves burrowed holes in the barbed wire, which deer were able to cross, the bison – the largest wild mammal colony on the continent – were split in half by the barbed wire, with about 300 on each side, cutting off their opportunity to exchange genes. The barbed wire fence belongs to Belarus today, and the Belarusians have no intention of dismantling it until the statue of Lenin has been removed. As a result, bison suffer from genetic degradation and are less resistant to disease and natural disasters, and are at risk of extinction.

If the bison were to become extinct in Europe, it would be another example of the collective disappearance of large mammals throughout history. Paul Martin, a paleontologist at the University of Arizona in the United States, has stored a pile of well-preserved dried feces in his laboratory, which he found in a cave in the Grand Canyon of the United States. It was left behind by a large sloth weighing about 100 kilograms, which is rare today, but when humans first appeared in the Americas, it could only be considered a sloth"Little man"。

At that time, there were many giant sloths on the American continent, the largest of which was about the size of today's elephants, and there were more than 1,000 sloths roaming the desert of the United States at that time. Biologists call animals that weigh more than 500 kilograms"Behemoth"In primitive times without humans, there were three times as many behemoths in the United States as there are on the entire continent today, when armadillos (small spiky mammals living in the Americas) were five times the size of modern armadillos, bears were twice as large as bears are now, horned, herbivorous arrow-toothed beasts were about the size of rhinoceros today, and tigers were nearly twice the size of tigers today. The behemoths that survived that era also included giant beavers, mammoths, mastodons, and more.

But the giant beasts in a region are always extinct in a short period of time, and extreme climate changes and exotic diseases may be the cause of extinction, but more paleontologists believe that human hunting is the real cause. Paleontologist Martin said"When ancient humans learned to use tools and group hunting, the gates of hell were opened.

He added that anywhere in the world, the timing of human emergence has magically coincided with the mass extinction of behemoths, first 60,000 years ago in Australia, then 13,000 years ago on the African continent, and then 6,000 years ago in the Caribbean islands.

What will the Earth look like in 20 years? What kind of high-tech will it be? Now it's up to me to decipher my imagination for you.

I think the Earth in 20 years will have a lot of high technology.

First, the means of transportation: the sun can be used for three purposes. I will now explain to you the role of this solar tri-purpose ship.

This solar-powered triple-purpose boat absorbs sunlight during the day and moonlight at night. Its three uses are: it can fly in the air, it can gallop on land, and it can dive and swim in the sea.

It's both eco-friendly and practical!

Second, stationery: smart pen. It can help us effectively in our learning, such as:

When we make a typo, it will clear out the wrong word; When we encounter a problem, it will teach us the way; When we can't write, it will become a dictionary for us to look up, and it will turn back into a pen.

Third, food: mood beans. It can do us a favor in moods, such as:

When you are very sad, eat a mood bean and you will be happy; When you are very lonely, eat a mood bean, and a person will come out to chat and play with you; When you are lost, eat a mood bean, and words of comfort will ring in your ears. Mood Beans are best suited for empty nesters and left-behind children.

All these high-tech products, each one is relevant to life, and each one is affordable and durable. In fact, I still have a lot to write, just to give you some room for imagination. Imagination is like a pair of magical wings that allow us to fly freely in the world of imagination.

I'm waiting for you to spread your wings and make the Earth more beautiful in ten years!

Today, 20 years later, October 16, 2024. Earth's technology has already reached its peak. All the countries have merged into the Earth Kingdom, and since then the Earth has no more smoke and consumption of war, thus surpassing other planets.

Since the discovery of the highly intelligent Martians in 2013, people have cooperated with the Martians in science and technology, and technology has quickly caught up. In the end, Earth's technology miraculously surpassed that of the Martians.

Wake up in the morning and hop on the funkiest flying saucer and go to Mars Chinese Restaurant for dinner. The flying saucer arrived at the Mars Chinese restaurant in 18 minutes. When you get there, you're dumbfounded, what if there's nowhere to stop the flying saucer?

Don't worry, I'll teach you, do you see the green button on the wall of the flying saucer? Press it, and the saucer will shrink to the size of clear glue, and you can go to eat with peace of mind! When you're done eating, lift the button and you're ready to recover.

Now that the car is outdated, scientists have captured the cloud in the laboratory, injected organic molecules into the cloud, and the cloud becomes a living thing, you just have to shout: "xx cloud!" "It will fly under your feet, drag you up, and it will go wherever you tell it to go.

At this time, people are already able to ride the clouds!

There are too many miracles created by science and technology in the future world, and the earth in 2024 is really amazing!
