Have you ever wondered what would happen if, one day, all human beings were suddenly wiped from the face of the Earth?
This article is quite a review material for advanced Chinese students. It covers vocabularies from multivarious topics, such as "environmental damage", "nuclear", "animals", and "construction". It is very normal for you to absorb new vocabularies from reading this article.
It can be said that human beings have ruled the earth for over hundreds of thousands of years, but the negative impact of humans on the Earth is far greater than the positive. The extinction crisis of earth creatures, global warming, air pollution, marine pollution, and deforestation have damaged the Earth. So many people have raised the question, if we suddenly disappear from the earth, what will the earth be like?
Many people will think that the earth will slowly return to its original appearance, just as we humans have never appeared before. The traces of our human existence above the earth will be slowly erased.
Once our humans suddenly disappeared from the earth, the various high-tech technologies that were previously controlled by humans, including nuclear reactors, will certainly explode. There are already more than 400 nuclear reactors on the earth. Nuclear reactors will burn, melt, and even explode one by one due to overheating. The explosion will create a nuclear leakage disaster; large amounts of radioactive material will be released into the air, rivers, and oceans. However, after this pollution occurs, the ecological environment on our planet will gradually become better, and the ocean air river will gradually become clean.
In a very short time, nature will regain control of the earth. The number of wild animals will also increase. However, some animals that depend on human survival, such as cows and sheep, will suffer. This also includes microorganisms, viruses, and the like. The HIV virus will also disappear from the earth.
Because there is no human management, all the concrete buildings we built will turn into lying waste. Metal buildings, bridges and towers begin to collapse due to corrosion. Buildings in many cities will collapse in 20 years, cracks will appear on the walls, and roof tiles will fall off. The roads will also lose its original function and turn into the former grassland.
What about plastic bags? Plastic bags can now be called the most devastating invention of all our human inventions. These plastic bags may not completely disappear on the earth for more than 10,000 years, because the chemical is difficult to be decomposed, and the traces of these plastic bags may still be found in the next 100,000 years.
After 10,000 years, our current building may have lost its traces, but the things we made with stone: The Pyramids, The Great Wall, etc., may still be preserved intact. Other than that, our human activity record on the earth will be completely erased, as if we have not been to the planet, which sounds really sad.
