Almost all plants and animals died out due to fallen 252 million years ago of deadly rain
Acid rains may have caused the deaths of almost everyone plants and animals 252 million years ago. Came to this conclusion scientists from the Massachusetts University of Technology. Global extinction occurred in the Permian period of the Paleozoic era and became one of the largest disasters in the history of the planet.
In the international community, the final opinion on the cause extinction of all living is not yet. According to one source, this happened. due to the fall of an asteroid, similar to that which destroyed dinosaurs 186 million years ago. Another version speaks of a sharp lower oxygen levels in the oceans. According to the third variant, increased tectonic activity led to disaster and volcanic eruptions. Massachusetts Specialists University of Technology focused their attention precisely on the third theory. They created several climate models where a large number of volcanoes regularly release various substances, to for example, sulfur, in the atmosphere. As it turned out during the experiments, the level of emissions was so great that acid rain could fully cover the northern hemisphere. “Imagine that you a plant that blooms happily in the Permian period. It’s getting hotter and hotter, but your view, quite possibly, managed to readjust to new temperatures. And then, quite unexpectedly, over the course of a few months it rains from the sky from acids, “one of the authors described what happened millions of years ago. research. In February of this year, a report by scientists on the latter, according to their words, a disaster on Earth. Calculations experts have shown that the sun will increase in volume, incinerating while our planet. The last earthlings will be extremophile bacteria adapted to life at high temperature and low oxygen content. But these microorganisms disappear: in 2.6 billion years the Earth will turn into lifeless hot desert.
