Forest fires have become very common now-a-days. In the last few years, millions of creatures have died due to fire in the forests of Amazon and sometimes Australia. Recently scientists have discovered the world’s oldest wildfire. Evidence of this fire spread 43 million years ago has been found in Poland and Wales.
Millions of years old charcoal found
Researchers at Colby College in Maine, USA, have found 43 million-year-old charcoal in Poland and Wales. Investigation revealed that the forest fire started in the Silurian period. Scientists say that at that time trees and plants were largely dependent on rain water to grow and grow. Very few areas were land or dry.
According to research, where there will be fire, there will be a special type of fungus called prototaxites, not trees. It could grow up to 9 meters i.e. 30 feet in length. Professor Ian Glasspool of Colby College says – it is surprising that at that time there was a fungus the size of the tree. We got this information in the investigation of plant fossils.
It is also necessary to have fire in the forests
According to Glasspool, three things are needed for a fire to start. First – fuel (trees and plants), second source of fire (lightning) and third oxygen to keep the fire burning. At that time the fire spread and there is still charcoal deposited on the earth, this simply means that then the level of oxygen was at least 16%. Today the level of oxygen in the atmosphere is 21%. That is, it also changes with time.
Earlier, the record for the oldest wildfire was 33 million years ago. Glasspool says that like everything else on earth, there is a need for wildfires. It plays an important role in the natural processes occurring on Earth.
