current geological research from Utah suggests the end-Permian extinction was mainly caused by burning coal,ignited by magma
soil has so far gone through five mass extinction events scientists are worried we’re on course to trigger a sixth – and the deadliest one happened 252 million years ago at the end of the Permian geologic period. In this event, coined “the remarkable Dying, and ” over 90% of marine species and 70% of terrestrial vertebrate species went extinct. It took about 10 million years for life on soil to recover from this catastrophic event.
Scientists have proposed a number of possible culprits responsible for this mass extinction,including an asteroid impact, mercury poisoning, and a collapse of the ozone layer,and acid rain. Heavy volcanic activity in Siberia was suspected to play a key role in the end-Permian event.
Things went from rotten to worse, and you can now begin to understand how life nearly died out. Global warming, and acid oceans,anoxia, not to mention a toxic atmosphere. We are lucky to be alive at all!Continue reading...
