Return to the earth's home composition

As far as we know, there have been humans on the earth for 5 years. Since the completion of the interstellar migration plan 5 years ago, humans have never set foot on the land of this home planet.

Now, in order to satisfy some people's curiosity, I will lead an expedition team back to the earth and this sad place.

after a tedious and long interstellar journey, our spaceship approached the earth. In our impression, the earth should be a blue ocean dotted with several green jade-like continents, and there is a huge ice sheet at the south pole of the earth. However, the earth before our eyes completely subverts it, and the original blue ocean is gray and lifeless. The mainland has become scattered islands, and the Antarctic ice sheet has completely disappeared.

The spacecraft entered the atmosphere, and the data showed that the carbon dioxide content in the atmosphere was over 65%, and the oxygen content was less than 5%. During the daytime, the air temperature reached 98 degrees Celsius, and there were a lot of toxic pollutants such as cadmium, beryllium, antimony, lead, nickel, chromium, manganese and mercury in the atmosphere. We suspect that the reason for such toxic air may be that the people on the earth discharged industrial waste gas without restraint at that time.

The spacecraft is close to the sea, and there is a thick dark red sulfuric acid mist floating on the sea. Fortunately, the hull of the spacecraft is made of high-density alloy, otherwise it would have been corroded. The seawater sampling shows that there are not only various highly toxic substances in the seawater, but also radioactive elements such as plutonium and uranium. This must be caused by people dumping nuclear waste into the sea.

It finally landed at the peak of the original Alps. The former world peak has become an island. There are no living things on the island, only rocks like monsters with claws and garbage discarded by human beings hundreds of years ago. The turbulent waves seem to talk about the harm done to it by human beings. You know how beautiful and rich it used to be, just like a graceful girl. This beauty lasted for billions of years, but it only took human beings hundreds of years. What a heinous crime

I woke up to find that it was just a nightmare, but it was also a prediction. The Chernobyl incident, the dead lake incident in North America, the oil tanker Cadiz incident, the Rhine pollution incident and so on 2 years ago are not turning the nightmare into reality? Humans should be alert!
