The earth is an excellent ecological earth, and it is precisely because of an excellent ecosystem that life and mankind are born. Therefore, the stability of the ecosystem is very important to human ecology and development.
It has only been around 5,000 years since human beings have entered the civilized era. During this period of time, the ecology of the earth has not changed much, and it has always been more appropriate. But all this has undergone major changes after mankind entered the industrial age.
The industrial age has allowed mankind to embark on the road of science and technology. I believe everyone is very clear about the power of science and technology. It not only makes people’s quality of life higher and higher, but also allows us to walk out of the earth to explore the universe. It can be said that human beings are now inseparable from technology. Although technology has brought us many benefits, everything has two sides, and there are advantages and disadvantages.
The rapid development of science and technology has also brought a crisis to the survival of mankind. This crisis is the emission of a large amount of industrial waste gas, especially the large amount of carbon dioxide emissions. According to research, the concentration of carbon dioxide in the Earth’s atmosphere has increased by 42.8% compared to before the industrial era. This is a very huge increase, and this data is still increasing over time.
The continuous increase in carbon dioxide concentration will bring about the greenhouse effect and make the earth’s temperature continue to rise. At present, the global average temperature has risen by 1 ℃ compared with industrialization. Some people may say that the large amount of carbon dioxide emissions is nothing more than making the earth’s temperature higher and higher, and it will have no other impact on the earth’s ecology. Is this really true?
If you think so simply, you are wrong. The consequences of the growing greenhouse effect are unbearable for us, and such an example happened 230 million years ago. In the process of studying geological evolution, scientists discovered that 230 million years ago, the earth ushered in a heavy rain that lasted for 2 million years.
Rainfall is a common and normal natural phenomenon on the earth, which can maintain and purify the ecological environment of the earth. But if the rainy climate lasts for a very long time, it will also bring a terrible ecological disaster, which will evolve into a mass extinction event.
230 million years is the era of the earth’s biological explosion. It was in the early stage of the Late Triassic, and 20 million years have passed since the third mass extinction. If it evolves according to normal life, there may be nothing about dinosaurs later. But nature is so difficult for people to think about, no one would have thought that a catastrophe is approaching quietly.
I believe my friends can imagine how serious the consequences of rain lasting for 2 million years are, and it can be said that it can completely reverse the ecology of the earth. This is also true. After 2 million years of heavy rain, 96% of species have become extinct. It took millions of years for the new ecosystem to recover, and it was this long rainfall disaster that made the dinosaurs, and the dinosaurs quickly rose to dominate the earth.
So how did this rain that lasted for 2 million years happened? Its occurrence is actually closely related to the massive emission of carbon dioxide. Of course, human beings were not born 230 million years ago, and there was no other intelligent life, so how did the massive carbon dioxide emissions come from? Mainly caused by large-scale volcanic eruptions.
Before the Carnian period, a large-scale volcanic eruption occurred in Langoria in western North America. This eruption process lasted for millions of years. Such a long volcanic eruption has caused a large amount of carbon dioxide to be emitted into the atmosphere, bringing about an increasingly serious greenhouse effect.
In the beginning, the greenhouse effect only brought about the continuous rise of the earth’s temperature, but as time passed, the carbon dioxide content became higher and higher, and the greenhouse effect became more and more serious. Finally, one day, it broke through a certain critical point and brought about a drastic ecological change. We all know that in the Carnian period 230 million years ago, there were no six pieces of land on the earth, only one piece, which we call Pangea.
Pangu Continent is a whole piece of land, and then it split into six major plates. Such a huge land made it difficult for the water vapor in the sea to penetrate into the center of the land. Therefore, except for the coastal areas, most of the land climate at that time was drier, dry and hot.
This climate, coupled with the continuous escalation of the greenhouse effect, finally triggered a drastic ecological change and brought an unprecedented heavy rain, which we call the Carnian flood event. So how did this long heavy rain evolve? In fact, the answer is not complicated. As the earth’s temperature continues to rise, the water in the ocean has also begun to evaporate into the atmosphere.
In this way, more and more water vapor in the atmosphere, as they move, they reach the center of the continent and reach every corner of the continent. We can imagine that a large amount of water in the ocean becomes water vapor and is stored in the atmosphere. Once the temperature of the atmosphere drops, what kind of terrible scene will the water drop down.
The continuous rise of the earth’s temperature has caused more and more ocean water to evaporate into the atmosphere. When this water vapor accumulates in the atmosphere to a certain extent, quantitative changes will cause qualitative changes, and then heavy rain will come. Rainfall will cause the temperature of the atmosphere to drop, which triggers a knock-on effect. The water vapor in the atmosphere continues to fall to the ground in the form of rainfall.
In the process of rainfall, the eruption of the volcano has not stopped, and carbon dioxide is still being emitted into the atmosphere. The temperature above the ocean is still maintaining a very high level, and the water in the ocean is still evaporating into water vapor. In this way, the ocean is constantly evaporating and inputting water vapor into the atmosphere, while the water vapor in the atmosphere is constantly falling on the land, and the evaporation and release lasted for up to 2 million years.
This is the origin of the Carnian flood event. Of course, in this two million years of time, it is not raining every day, and there are periods of rain. It’s just that it rains most of the time. This climate keeps the originally arid land moist for 2 million years.
We can imagine that Pangea was originally a dry land with little rainfall. The organisms living on this land have already adapted to this arid climate, and nature has allowed these terrestrial organisms to adapt to drought in the direction of evolution. land. However, the arrival of this rainfall that lasted for up to 2 million years turned the dry continent into a humid continent. It was difficult for a large number of organisms to adapt to this climate, and the mass extinction of new organisms began.
After the baptism of the Carnian flood event, a large number of ecological niches were vacant. At this time, the dinosaurs adapted to this climate and began to rise, and opened a period of prosperity of 160 million. And this long rain also made the early mammals appear. Unfortunately, it was the age of dinosaurs. The mammals were too weak and could only be hidden, quietly waiting for another opportunity to come.
At this time, it was 160 million years ago. Until 65 million years ago, the asteroid hit the earth again and caused ecological drastic changes again. Dinosaurs could not adapt to the drastically changed environment, a large number of extinctions disappeared, and the dinosaur era ended. In this upheaval, mammals have adapted to the new ecological environment and began to rise, replacing dinosaurs as the new overlord of the earth.
After reading these, I believe that my friends also understand that the large amount of carbon dioxide emissions eventually caused 2 million years of rainfall. And now human industry has also brought about a continuous large amount of carbon dioxide emissions. If such emissions are not controlled, then over time, once the atmospheric carbon dioxide content has also reached the level of 230 million years, then the new A long round of rain may also be staged again.
If there is another rain on the earth that lasts for tens of thousands of years in the future, the ecological niche of the earth will also be reshuffled, and a large number of species will become extinct. Although human beings are intelligent beings with the power of science and technology, in the face of such natural disasters, whether we can survive is still an unknown, unless we have the ability to migrate to other planets.
