It was not until the end of the 50s of the last century that human satellites took the first picture of the earth ** above the earth, and mankind was fortunate enough to see the whole picture of the earth. It's a blue planet, a beautiful planet that you won't want to return to, whether you are a celebrity or a mediocre ordinary, all of us live on this not very big blue planet, we are the only home for all of us. In the era of rapid technological development since the beginning of human progress 300 years ago, the development of industry requires a large amount of earth's resources.
Human beings are endlessly demanding from nature, forests are disappearing on a large scale, the air is seriously polluted, and the water bodies are gradually deteriorating. The once blue sky and clear rivers have now become a luxury in many places, and even breathing, the most basic element of human existence, has become so luxurious, and the air pollution has made many people unable to breathe any clean air.
-
Fifty years ago, the air was still fresh, the rivers were blue, the water was crystal clear, and the forests were still patchy. Today, 80% of the Earth's primary forests have been destroyed, countless lakes have shrunk and disappeared for various reasons, and rivers that were once swimmable have become muddy and smelly, and you can no longer see the horizon when you climb to the top.
-
The changes that humans have made to the earth's environment are obvious, 50 years ago it was not as hot as it is now, and now the most difficult season is summer, which is obviously much hotter than a few decades ago, and there are quite a lot of diseases caused by high temperatures today. The cool and suitable weather that used to be is really not many anymore, and extreme weather is increasing year by year, making people's lives more and more difficult. The most direct effect of global warming is the increase in sea levels, and if left unchecked, it is estimated that many low-altitude coastal cities will be threatened by seawater in the future.
-
It can be said that compared to the earth 50 years ago, although science and technology have developed, people's lives have become better, but the earth's environment has become very worrying, only a few decades, the earth's environment has suffered such a huge damage, if not remedied, maybe in another 50 years the earth's environment has been able to accommodate human survival.
-
How has the Earth changed today compared to the Earth 50 years ago? In the past, people did not have all kinds of high-tech products, nor did they have any industrialized equipment, people used primitive tools, whether it was travel or daily life, the energy consumed was relatively green, but with the rise of the industrial revolution, everything changed.
-
In terms of carbon dioxide emissions, in order to facilitate people's travel, people invented the car as a means of transportation, and now the car is a necessary travel tool for every household, and a large number of exhaust gases emitted by cars enter the atmosphere every day, resulting in an increase in the concentration of carbon dioxide in the atmosphere, resulting in a greenhouse effect. Today, the earth is not like 50 years ago, its temperature is gradually rising, resulting in a situation where the winter is not cold, but the summer is very hot.
-
Due to global warming, the snow and ice in the Antarctic and the Arctic are gradually melting, and the sea level is rising, which poses great danger to many coastal cities. Located in the southern Pacific Ocean, Tuvalu is a country of nine coral islands and is also known as the fourth smallest country in the world. Because of the rise in sea level caused by global warming, the people of this place and ** are trying to fight the problem of sea level rise in order to survive, but in the end it still fails, and some experts** will completely disappear in 50 years at most.
-
Today's earth is like this, the environment can no longer be compared with 50 years ago, human damage to the earth can only be saved by human beings, human beings are currently able to restore the original appearance of the earth, it depends on whether human beings can take action as soon as possible.

In the year 2050, the beautiful Earth will no longer have the glorious history it once was, and now I am a citizen of Mars, and now I live in a place called Xingdai! Want to know why? Let me tell you!
Due to the fact that in the past ten years, the earthlings have not taken care of the environment, and the atmosphere has been seriously damaged, and without the protection of the atmosphere, the garbage on the earth is floating in the air.
In the year 2050, the beautiful Earth will no longer have the glorious history it once was, and now I am a citizen of Mars, and now I live in a place called Xingdai!
Want to know why? Let me tell you! Due to the fact that in the past ten years, the people of the earth do not care for the environment, the atmosphere has been seriously damaged, there is no protection of the atmosphere, the garbage on the earth is floating in the air, of course, people are the same, the current earth has become deserted, a few days ago I used the "eye of the sky" to look at the current ...... of the earthIt's terrible, the forest has become an unmanned processing plant, and the sea has become a relentless desert ......
Now that the Martians are hospitable to us humans, I have sent out a super invincible radio on the Martian belt to advise the people of other planets in the universe: protect your planet and not let the tragedy of Mother Earth happen again!
I wish it was a naïve fantasy .........

One night, I was out for a walk alone. Suddenly, a dragon lunged at me, and I fled. After a while, when I saw that the dragon did not move, I approached him, and when I saw that the dragon's gaze was so gentle, I asked him:
What's wrong with you? The dragon said, "I am wounded."
I said, "Come to my house." We can also be friends.
He said, "Okay." After a few days, he said:
I'll give you a moment of planes-traveling dragon scales. With that, he left. I think:
Since you can travel through time and space, let's go to Earth in fifty years.
With that in mind, I wore dragon scales around my neck. Then I said, "Take me to Earth in fifty years."
As soon as I finished speaking, I entered a cave surrounded by blue yin and yin, like a vortex channel. It didn't take long for me to come to a place of great beauty, a paradise, 50 years ago the earth was full of houses, the water was very dirty, the air was not clean, but the sky was high and clear, the air was fresh, and the birds and flowers were everywhere. As soon as I looked down, I saw a river flowing endlessly, and I picked up a handful of water and drank it without saying a word.
I finished drinking the water and walked to the front, when a sudden person really startled me, and I asked him, "Do you live in **?" Why didn't I see it?
The man said, "My name is Jerry, we used to destroy nature arbitrarily, and then the environment became worse and worse, so we started to protect the environment, and finally we lived in a cave, go, I will invite you to have a meal." I said
Good. "Their food is as light as water, but it's filling. After eating, I went home.
Yes! It smells so good! I ran to the kitchen, and with a "dang" the dragon's scales shattered. I thought: Okay, the earth will be so beautiful in 50 years, but the food is still the incense burned by my mother now!

It's unimaginable, the world is changing too fast, and accidents can happen, so it can't be **.

With the changes of the times, human beings have been making continuous progress with the times, from a personal point of view, the current earth, its appearance contrast, before the seventies and eighties of the last century, a face inside has undergone great changes. The reason for this is that human beings have changed nature and insisted on using science and technology to develop human society from the beginning. Especially now that people find that the earth's climate and pollution are getting more and more serious, the gap between the earth and the earth half a century ago is as follows.
1. The color of the sky has changed dramatically. First of all, the first point is that the most impressive thing for us is our sky, in the seventies and eighties, the sky was full of blue sky, so that the sky was considered to be the same color as the sea and the sky. In today's sky, all we have is black smog and factory exhaust fumes, which directly pollute the blue sky we see now.
It is precisely because of this that the air pollution in one of the rings of the earth's interior is extremely serious, which can be found in the change of color of the sky. <>
Second, water resources are becoming more and more depleted. Secondly, and the other point is that with the rapid development of the population and the increasing demand for resources, their groundwater is already facing the problem of depletion in many areas. Because of this, many regions now have a source of water from other regions, whereas in the past there was a small river in each area, but now it has only a waste water ditch.
3. The earth has become potholed. Finally, many areas are now pitted, and the main reason for this is due to the exploitation of mineral resources and the use of petroleum resources. Because human beings have to use these resources, they must constantly exploit the ground, and the protective measures are not particularly good, resulting in many potholes on the ground.
-
Half a century ago, the earth was full of water, there was very little land to live on, deserts everywhere, and there was no green vegetation. Half a century later, the earth's land is slowly increasing, and green vegetation is gradually replacing deserts.
-
According to the comparison of **, we can find that the outer brilliance of the earth is much dimmer, and the surface of the earth is also very different, where it should be surrounded by green, but now it is replaced by yellow.
-
After years of multiplication, the earth and the sea must have undergone many evolutions, and the past half century may have only been primitive and Jurassic, etc., and now that technology is also very advanced, it will naturally be very different from before.
-
At that time, because of the continuous progress of science and technology, human beings will use many ways to solve this problem, such as:
1.At that time, most of humanity will inhabit other planets.
2.There is supposed to be an artificial atmosphere on Earth to block ultraviolet rays.
3.New instruments will be used to replenish the ozone layer over the North and South Poles.
4.Excess CO2 gas from the earth will be pumped out.
5.At that time, the large-scale use of CO2 gas for industrial products will be stopped.
There are many ways to solve this problem. So you don't have to worry about the destruction of the earth in the future.
-
Forty years ago, the earth's environment was good and unpolluted, but now the air is very poor due to industrial influences.
-
Forty years ago, the Earth's atmosphere was cleaner and the air was cleaner, making a big difference.
-
The difference between the earth 40 years ago and the present is the environment, which was much better before.
-
Forty years ago, the earth may have been a little better, but technology was not as advanced as it is now.
-
The earth 40 years ago was similar to it is now, because time is not far away.
-
The earth is more technologically advanced and environmentally friendly than it was 40 years ago.
-
Forty years ago, the earth's environment was very good, but now the air pollution is particularly serious.
-
Forty years ago, the key to the earth was at least much better than it is now.
-
Forty years ago, the earth did not have, and now the earth is so polluted.
-
At that time, the environment would be better than now, with more greenery and animals.
Rats that breed infinitely in a space that is meters long and meters long, have no worries about food and clothing, no natural enemies and no disasters, only space limitations, this place, which John Carr called "the utopia of rats", simulates limited space and other perfect earths, but the final result is the result of just wanting to wait for death slowly.
Based on the determination of the decay rate of radioactive materials on Earth, it is known that our Earth has existed for 4.6 billion years, that is, our Earth was born 4.6 billion years ago. >>>More
A song from 50 years ago? That's the song of the fifties and sixties of the last century? >>>More
I used to be enthusiastic, generous, and helpful, and I did it as if I were my own. Now I have become indifferent and can be appropriate.
Personally, I think it is to remember history well and not forget the national shameOur ancestors used their wisdom and sweat to lay down the current China for usWe must cherish it, cherish the peace that has been won so hard, cherish every policy of the country to benefit the people, and at the same time, we must continue to work hard and continue to work the basis of not forgetting our original intentionThis is an era of rapid development every day, and if you don't advance, you will retreat, so for the sake of the beautiful future of the motherlandWe must continue to work hard. >>>More
