Extinction is the complete demise of a species. It takes place when all individuals of a species die out. Extinction has occurred throughout the history of life on Earth. It is the ultimate fate of all species. In fact, it has been estimated that 99.9% of all species that have ever lived on Earth are now extinct.
They found that the current extinction rate was more than 100 times higher than in periods when Earth was not going through a mass extinction event. Since 1900, the report says, more than 400 more vertebrates had disappeared. Such a loss would normally be seen over a period of up to 10,000 years, the scientists say. The study-published in the Science Advances journal-cites causes such as climate change, pollution and deforestation.
