According to US and Australian scientists, 250 million years ago, the Earth has undergone a " mass destruction " that caused about 95% of species to live in the water and 70% of terrestrial species disappear, the structure of species remains. surviving on the oceans is also fundamentally altered. They warn that changes to the current ecosystem created by humans can also lead to similar disasters.

In the recent issue of " Science " magazine, experts said that after classifying and checking aquatic species data for the past 540 million years, they discovered most of the ancient species did not move. or searching for food was largely destroyed after that "mass destruction". More complex species (such as crabs and snails) move for food, surviving the tribulation.

This "biological destruction" occurred around the end of the Permian, about 2,500 million years ago, when the Earth was envisioned to be only one continent with an ocean surrounded.

According to experts, the "mass destruction" of the end of the Permian period changed not only the variety of species but also the structure of the marine ecosystem. These changes can be repeated in this day and age, if people continue to reduce the quality of marine ecosystems to levels of 550 million years before the explosion of animal diversity. This is a warning about the consequences of human behavior for today's ecosystem.
