Comparing the earth now with the earth 47 years ago, do you feel scared and worried?

The earth has been the home of human beings for millions of years. In ancient times, people did not know what the earth looked like or whether it was beautiful or ugly. As humans entered the path of scientific and technological development, they soon realized their dream of flying into the sky, and began to explore the universe beyond the earth.

When people step out of the earth and look at the earth from space, they realize that the earth is so beautiful, with blue sky, white clouds, and continuous mountains distributed on this beautiful sphere. I believe many friends have seen photos of the beautiful blue planet on the Internet. It was actually taken by Apollo 17 on December 7, 1972, nearly 5,000 kilometers away from the earth. Through that photo, mankind for the first time completely saw what its own planet looked like in the universe.

Now 47 years have passed, what will the current panorama of the earth look like? Some people may say that it will still be as beautiful as it was 47 years ago. And more people believe that the earth now is no longer the earth it was 47 years ago, and it has long lost its beauty in the past. In fact, many people can feel the changes in the earth from the natural changes around them.

I believe that many friends born in the 60s and 70s feel the deepest. Take the editor as an example when he was a child. The editor was born and grew up in the countryside. When he was young, he would I would go out with my friends. The wilderness at that time was really beautiful, with all kinds of flowers and plants blooming, butterflies flying, and a beautiful pastoral scene.

What is the scene like in the wild today? The two wild conditions have undergone tremendous changes. Nowadays, flowers and plants are rarely seen. There were many wild flowers in the past, but now it is difficult to see them. The editor has not seen beautiful animals like butterflies for several years, so I went there specially this year. In a place farther away with many wild flowers, I was lucky enough to see some butterflies.

Although this is just the scene of the editor, it can cover the whole world. It can be said that there is very little pollution in the countryside where the editor lives. There are no large-scale industries or polluting factories. However, the deteriorating global environment has still affected this once beautiful mountain village. Just imagine that the situation in other places with severe pollution will be even more serious.

When we were children, we looked up at the night sky and could see the sky full of stars. Now when we look up at the night sky, we see only a few stars. It’s not that these stars are gone. They are still running in the universe. It’s just that The pollution of the earth has covered the sky, making it impossible to see more stars.

With the continuous emission of greenhouse gases, the greenhouse effect has caused global temperatures to continue to rise, El Ni?o phenomena occur frequently, and extreme climates such as heavy rains and droughts are becoming more and more frequent. The ice and snow in the Arctic and Antarctic continue to melt, tens of millions of years of frozen layers are beginning to recover, and ancient viruses and bacteria are also beginning to slowly wake up. Nowadays, there are fewer and fewer dense forests, rivers are not as clear as before, and there are very few wild places where birds were singing and flowers were fragrant in the past. The stars that used to fill the sky are now hard to see at night. Now every spring, sandstorms are going crazy, the sky is covered with yellow sand, and the desert is constantly devouring fertile farmland.

When we realize that the earth’s environment continues to deteriorate, the earth is no longer the earth 47 years ago, and the current scene of the earth is no longer as beautiful as it was 47 years ago. Looking at the earth from space now, although it is still There is a blue planet that is different from other planets, but if you look carefully, you will find that the blue color is not as blue as before, and it has some grayish things.

And due to the rapid development of science and technology, space junk generated by satellites, spacecraft, etc. is also increasing day by day. There is now a large amount of space junk distributed in the earth’s orbit. They surround the earth. From space, you will Seeing that these space junks are constantly surrounding the Earth, it is possible that in the future, the Earth we see will be a planet covered with thorns, and we will never see the beautiful blue planet we once had.

For a planet, 47 years is an insignificant time. The earth is 4.7 billion years old. Billions of years of changes have not changed the beauty of the earth. But it only took humans 47 years for a beautiful blue planet to begin to dim. Technology has changed people's lives, changed human civilization, and made human civilization gradually stronger. But at the same time, it has also quietly changed the earth, slowly turning it into an unsurvivable planet.

Of course, it is difficult for us to change these. Although scientists have been working hard to change the earth's deteriorating environment in recent years, they have achieved little. Take the content of carbon dioxide as an example. In the past ten years, scientists have been strengthening standards for carbon dioxide and other emissions. Strict emission standards have emerged one after another in an attempt to restrict greenhouse gas emissions.

However, according to scientists’ detection of carbon dioxide in the earth’s atmosphere this year, the content of carbon dioxide in the earth’s atmosphere has reached a new high in 2019. The reason why this situation occurs is that human technology is developing rapidly. Although we continue to raise the emission standards for automobiles, we will soon enter the National VI standards.

Car exhaust emission equipment is becoming more and more advanced, and the carbon dioxide emitted has indeed reduced. However, the number of fuel vehicles is increasing sharply. There were only so many cars in our country 10 years ago, but now the number of cars is more than 10 It has doubled at least several times a year ago, and the sudden increase in fuel vehicles has only increased carbon dioxide emissions.

Cars are only one aspect of carbon dioxide emissions, and the same is true for other aspects of technology. Rapidly developing technology cannot reduce carbon dioxide emissions.

Therefore, if human beings want to develop rapidly, environmental pollution and ecological damage are inevitable, and the future of human beings can only be placed in space. When our technology is developed enough and we enter interstellar civilization, , we can go out of the earth to explore exoplanets, find a second earth suitable for human survival, and then immigrate to the new earth to live.

With advanced technology, we can move the earth's heavy industry to other planets, such as the moon and Mars. In this way, the earth will have no sources of pollution, and the earth itself has a strong ability to recover itself. As long as the earth has no sources of pollution, the earth's ecological environment will still return to the beautiful scenery of the past after hundreds or thousands of years of self-recovery.
