Write a science fiction essay Earth in a Hundred Years .

Ah, I'm so sleepy! "I crouched down at my desk, feeling dizzy, sighed, and fell asleep.

Today is the day of 2113, I am traveling in space in a spaceship, and today I am returning to my cue ball, the earth. Ah, it's exciting, Earth, what will you become?

When I flew to Earth, I was surprised to find that Earth was no longer the beautiful blue planet it used to be. Today, when viewed from the outside, the surface of the earth is full of yellow earth, and from the inside, there is hardly a single green plant, animals and plants are on the verge of extinction, and even the thick atmosphere has been destroyed by high concentrations of carbon dioxide. I was amazed to look at the changes in the earth over the past few decades, and to find that human beings are doing incredible and unforgivable things!

People uncontrollably reclaim land and build high-rise buildings; destroying forests, destroying grasslands, severely destroying green vegetation, but doing nothing; Bombing mines, digging coal mines, blocking and polluting the source of rivers; People are intrigued, openly and secretly, fighting for power and profit, regardless of brotherhood, regardless of the righteousness of husband and wife, only thinking about their own interests, regardless of the life or death of others; The virus seriously endangers human life, but people are still indifferent, and some even say that it is a ...... of "too many people".

Oh, my God! How so? Could it be that human civilization has returned to ancient times? Is it ......How so?

Suddenly, a large hand slapped me. I was awakened. Yes! It turned out to be Dad!

When I woke up, I was deep in thought: If humans continue like this, will this be a dream??? I got it.

That seems pretty good to write, right?

First of all, to protect the earth, there must be something that threatens the earth, and it must be science fiction, which is simple.

To be simple, the climate and environment, what global warming, the glacial age, the hole in the ozone layer, or man-made nuclear war, space war, or aliens.

Then, how do you protect the planet, that's it.

By the way, pay attention to time, this is very important, now when it comes to the issue of protecting the earth, the main plot should take place in the future, and you can add to the past or the present.

For example; To put it simply, nuclear winter.

A short introduction to the first nuclear bomb, plus the time, is as if I saw it, and then now 22 years or something, come to the sentence "The weather forecast says that the weather is good today, the temperature is high, 0 degrees Celsius is 60 degrees Celsius, the wind is 9, it is suitable for going out." "Then start writing about yourself, what is necessary to live in an underground base, and you can also go out with a mecha like Gundam protection, by the way, the nuclear war a hundred years ago, that is, the cause of this nuclear winter, your job can be to plant a nuclear bomb, today is the last one, write a good point here, and then there is a nuclear bomb**," The dust produced by the nuclear explosion is all over the northern hemisphere, and the sunlight absorbed by the earth this year will be last year's, and next year we will usher in summer! The name can be next summer or something.

I love to read science fiction, you can look at the science fiction world, maybe you can directly find one, periodicals, buy at the newsstand, I recommend you an author, my most admired science fiction writer, Liu Cixin, look on the Internet, look at his books, may give you inspiration.
