Sixth Mass Spieces Extinction

After 70 million years, we are sending a more complex life, and it removed the land from the ocean. The extinction of the late Devonian era was not a single event, but a number of small scale extinction cases such as the Kellwasser case and the Hangenberg case combined to create a major major extinction case. The third mass extinction occurred at about 245 mya, known as the Perm-Triassic extinction. "More than half of biological families died, 90% to 96% of marine organisms on Earth disappeared.

As the extinction of the Holocene may be the Ordovician - the extinction of the Silurian, the extinction of the late Devonian, the extinction of the Permits - the Triassic, the Triassic - Miluo incident, so " It is also known as extinction. The sixth annihilation incident after the extinction case, and Cretaceous - the extinction of the Paleogene. Mass extinction is characterized by at least 75% of the species geologically lost during a short period of time. There is no general agreement on the beginning of the Holocene or artificial extinction and the beginning of the quaternary extinction, including climate change that resulted in the end of the last glacial period and its end. Otherwise, it should be treated as a separate event. In many cases, especially on geographically isolated islands, it has been claimed that even with minimal hunting pressure it is sufficient to destroy large fauna. Plants suffered great loss only during recent extinctions.

Due to large volcanic eruptions, large ice age, atmospheric shock, and continental conflict, life on Earth has experienced five extensive biodiversity extinctions in a long history. However, some scientists think that the sixth mass extinction began. It is executed by humans. We became the largest predator of greed worldwide. "Science" magazine says it destroys seeds at 1000 times the speed of nature. 97% of the world's vertebrates are now humans or our farm animals - only 3% are wild animals
