Answer 1

The "great dying," also known as the Permian-Triassic extinction event, was partially caused by bacteria producing large amounts of toxic methane. This event is believed to have been influenced by various factors, including volcanic activity, climate change, and the resulting anoxia in the oceans, which were exacerbated by the metabolism of methane-producing bacteria.
