The “leaves” 23 million years ago are clearly visible in texture and are sending out warning signals!
Before human civilization, the earth experienced five mass extinctions, and each mass extinction of animals and plants led to a serious setback on the earth, and few lives could enter the next cycle. In order to find the only traces of life, scientists spend their energy digging fossils or remains, trying to understand the changes of the earth. It is of great significance to infer the changes of the earth by mining fossils, because most of the ancient fossils can be preserved and have high research value.
Scientists find leaves 23 million years ago
Recently, a scientific research report shows that scientists have found a complete fossil again, which is suspected to be closely related to climate change. What’s the matter? The fossil looks like a “leaf” that formed about 23 million years ago. It was found in a farm near New Zealand. This area belongs to the leaf fossil deposit area. Because it was once an ancient lake area, the oxygen content was quite low, so it preserved such a perfect structure. The “leaves” 23 million years ago are clearly visible in texture and are sending out warning signals!
Not only this “leaf”, but also other fossils are well preserved. Through the study of this leaf, scientists found a link between atmospheric concentration and carbon dioxide, and made an accurate prediction of future climate change. The texture of this leaf is clearly visible. In addition to some small holes, it may have been bitten by insects. This phenomenon has been extremely common. In this dry lake bottom, scientists have also found other algae, plants, fungi, etc. in ancient times, climate change is a necessary process.
What was the earth like?
At first, the earth’s high temperature spread all over the melt, and then the temperature cooled down, and new life was born. In the evolution period, the earth experienced the baptism of high temperature, and ushered in a small ice age, and the concentration of carbon dioxide also changed. The survival of this ancient leaf needs photosynthesis, so the reference value is still very high. From the other plant residues excavated, we can trace back to the earlier period. At that time, the average temperature of the earth was 3 ~ 7 degrees higher than now, the ice layer gradually disappeared, and it was at the critical point of climate. The concentration of carbon dioxide increased year by year, which was a change process in the early stage of the earth.
From the analysis of these leaves, it can be seen that today’s carbon dioxide concentration is no lower than that in ancient times, which attracts the attention of scientists. It is urgent to protect the earth. This sense of crisis lurks around human beings and has long crossed that boundary. The climate is developing in the direction of extremes, which is ultimately related to human activities. Before the early days of the earth, there were no human beings. In the past, since the existence of human beings, excessive deforestation and emission of the atmosphere led to the increase of carbon dioxide concentration.
With global warming and wildfire raging, it’s time for human beings to worry about the earth’s environment. However, the vast majority of people do not seem to wake up and try their best to find the second earth. No matter whether the second earth can successfully migrate or not, what we should do now is to pay attention to the earth’s environment. What do you think of the 2300 year old leaves unearthed by scientists? You can leave a message for interaction.
